阀门操作维护保养手册

1、手动阀门的正确操作手动阀门是设备和装置上使用很普遍的一种阀门，它是通过手柄、手轮来操作的。

一般情况下手柄、手轮顺时针旋转规定为关闭方向，逆时针旋转规定为开启方向。

但有的阀门启闭方向与上述相反，故操作前应注意检查启闭标志后再操作手动阀门，其手柄、手轮的大小是按正常人力设计的。

因此，在阀门使用上规定：不允许操作者借助杠杆和长扳手启、闭阀门。

同时，手柄长度、手轮直径小于320mm的，只允许一个人操作；直径等于或超过320mm的手轮，允许两人共同操作，或者允许一人借助适当的杠杆(一般长度不超过0．5m)操作。

但隔膜阀、非金属阀门是严禁使用杠杆或长扳手操作的，也不允许用过大、过猛的力关闭阀门有的操作者习惯使用杠杆和长扳手操作手动阀门，认为关闭力越大越好，其实不然。

这样会造成阀门过早损坏，甚至酿成事故。

实践证明：除撞击式手轮外，过大过猛地操作阀门容易损坏手轮、手柄，擦伤阀杆和密封面，甚至压坏密封面。

其次，手轮、手柄损坏或丢失后，应及时配齐，不允许用活扳手代用。

闸阀和截止阀之类的阀门，关闭或开启到头(即下死点或上死点)时要回转1/4～1/2圈，使螺纹更好密合，以有利操作时检查，以免拧得过紧损坏阀门。

较大口径的蝶阀、闸阀和截止阀，有的设有旁通阀。

旁通阀的作用是平衡进出口压差，减少开启力矩。

开启时，应先打开旁通阀，然后再开启大阀门。

开启蒸汽阀门前必须先将管道预热，排出凝结水。

开启时要缓慢，以免产生水锤现象，损坏阀门和设备。

开闭球阀、蝶阀、旋塞阀时，当阀杆顶面的沟槽与通道平行时，表明阀门在全开启位置；当阀杆向左或向右旋转90。

时，沟槽与通道垂直时，表明阀门在全关闭位置。

有的球阀、蝶阀、旋塞阀以扳手与通道平行为开启，垂直为关闭。

三通、四通阀门的操作应按开启、关闭、换向的标记进行，操作完毕后应取下活动手柄。

对有标尺的闸阀和节流阀，应检查调整好全开或全闭的指示位置。

明杆闸阀、截止阀也应记住它们全开和全闭的位置，这样可以避免全开时顶撞死点。

The sides of the unit should be at least one foot away fromthe wall or soft goods.·Do NOT cover an operating machine.·The appliance is not to be used by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.·Children being supervised not to play with the appliance.·Use the Vulcan only as prescribed, any other use may cause fire, shock or injury to persons.·Always unplug unit when not in use. See proper shutdown procedure in this manual.·SAVE THESE INSTRUCTIONSOperating InstructionsUnpacking: Check unit for damage. Do not operate this unit if damaged.1.Inspect Vulcan and the power cord for any damages before using. Do not use the system or the cords if damaged. Read Caution statement.2.Locate the unit in safe DRY area. See WARNINGS and CAUTIONS on page 2.3.Turn all heater switches OFF and Temperature Control switch to MAN.4.Plug your unit into 230VAC/1 phase, 30 or 50 amp power supply. POWER light will come ON.5.Note: Use only power source with ground and over-current protection. Recommended EDPCORDKIT: Dryer/Range, 4 prong, 8’6/3-8/1 125/250VAC 30/50 Amp plug.6.Turn AIRFLOW controller knob from OFF to your required speed and the AIRFLOW status light will turn ON.7.When AIRFLOW light is on and internal heater temperature is less than 180° F, the SAFETY light will turn ON.8.Turn ON the individual heating elements, starting with #1. For 30 amp power supply only #1, 2 & 3 elements (20,500 BTU) can be ON. For 50 amps, all 6 heaters (37,000 BTU) can be turned ON.Auto Temperature ControlSwitch temperature control switch to AUTO position. On Temperature Controller, use up/down arrows to set the desired temperature Set Point (SP) up to 160° F. Locate the thermocouple end in measured area or targeted material. The Temperature Controller will display the measured temperature and selected set point SP. When SP temperature is reached, Temperature Controller will turn heating elements Off and automatically restart when temperature drops 10° F below the SP. Change your SP as needed at any time.After the heater stabilizes at your required temperature, check the operation of the heating elements. If the Temperature Controller is frequently turning the heaters OFF/ON, reduce the number of active heaters or increase the air flow.Manual Temperature ControlTemperature Control switch should be in MAN position. To regulate the heater temp., activate only number of heating elements required for the heat rise. Increasing airflow will decrease the exhaust air temperature.Internal heater temperature is limited to 160° F. When this high limit is reached, thermo switch TS-2 turns all active heaters off and automatically restarts at 135° F. Note: The exhausted air temp. may be considerably higher then 160°F.If the 160°F thermo switch is frequently turning the heaters OFF/ON, reduce the number of heating elements or increasethe air flow to stay below 160° F.Shut Down ProcedureThe heat energy stored in the heating elements could heat up the outer surface of the unit if it is shut down without any cooling down period. To prevent this and to maximize the life of the heating elements, follow this procedure:1.Place into manual mode, and switch all heating elements to OFF position2.Allow blower to run for at least five minutes or until air flow has cooled3.Switch blower to OFF position4.Disconnect cords and store the unitOperation TipsFor the Vulcan model, ensure thermocouple is plugged into the unit before powering on. For the Vulcan RT model, ensure the remote is plugged into the unit before powering on.To minimize the On and Off cycling of the heaters, balance the airflow and the number of active heaters by watching the heater switch lights to see the ON/OFF operation.The temperature Safety switch will turn the heaters Off and ON between 180° and 150° F. This is a safety cutoff and heater should not operate this hot.When the safety switch shuts the heaters down, the SAFETY light also turns off.When internal heater temperature reaches 160° F limit, the exhaust air temperature would be around 180° F. Take this in consideration when ducting hot air to a remote containment area.Vulcan delivers up to 37,000 BTU and at 400 cfm of air flow at temperatures from ambient to 160° F. The heater outlet can be ducted to deliver heat where needed. The air intake could be open to ambient air or ducted from a dehumidifier.At air flow of 350 cfm, operating with all 6 heaters, the temperature rise is 95° F above the ambient air. When operating on 30 amp circuit with 3 heaters, the temperature rise is 55° F. At lower air flow, the heat rise will be higher. At 475 cfm, the heat rise is 75° F with 6 elements on.Vulcan is designed for indoor use only and it is important to locate heater in dry, safe location. Heater exhaust must be 3 feet or more from a wall or any soft material. When ducting hot air to a remote area, using a shorter duct reduces heat losses.Please read Safety warnings before starting to operate your new Vulcan.Unit may be operated in horizontal or upright position with exhaust aiming up. Do NOT lay unit on air intake side or block the outlet.The Heater must be plugged in to a 250 VAC power supply equipped with over-current protection. The heater unit blower must be running before the safety interlock circuit enables the heater elements to be turned on. Depending on the 30 or 50 amp power supply, 3 or 6 heating elements can be selected. Since there are many variables from project to project, we recommend setting your air flow first and then start to turn the heating elements on. Depending on your ambient temperature, selected airflow and required temperature rise, the number of operating heating elements will vary.The Vulcan offers maximum versatility with variable airflow and 6 heating elements which can be individually turned on as needed. After manually setting the air flow and number of heating elements, the heater temperature could be regulated inMAN (Manual) or AUTO mode. In MAN, the High temperature switch is set to shut off heating elements when internal heater temperature is 160º F and restart at 135º F. In AUTO mode the Temperature Controller measures remote air or material temperature with a thermocouple connected to the temperature controller.The measured temperature is compared with selected Set Point which cannot be higher than 160° F. Temperature Controller automatically turns selected heating elements on and off to maintain the set point.The Safety circuit protects the unit from overheating. If the heater loses a minimum required air flow, all the heaters will shut down until the airflow is restored. Also, if the internal heater temperature reaches 160° F, the safety thermo switch TS-1 shuts the heating elements down and restarts automatically at 150° F.Electrical Requirements: Vulcan unit requires 250 VAC/ 1 Phase power source with over-current protection rated at 50 amp maximum. It can be plugged into a dryer/range outlet, generator or hardwired into an electrical panel by a certified electrician. The amperage draw will depend on the number of elements engaged. Each element drawsabout 8 amps. For maximum heat gain, use all 6 heating elements. Note: Heater can operate on 208 VAC at reduced heat output.Operator’s Controls1.On the Vulcan model, air flow is controlled by changing speed of the blower. Turn the control knob from OFF to anywhere onthe dial and check that AIRFLOW light turns ON. On the Vulcan RT model, air flow is a fixed speed when the unit is on.2.The digital hour meter measures the cumulative time the unit is running to tenths of an hour. It stores and displays the totaltime when the unit is disconnected from power supply.3.Temperature Controller displays measured temperature, Set Point and provides automatic ON/OFF heaters control.Temperature Controller is programmed to maintain user selected set point temperature when AUTO mode is selected and remote thermocouple is connected to thermocouple on the control panel (figure 1 point 4). Place the sensor end incontainment area to monitor air or materials temperature to prevent overheating delicate parts of structure.4.Thermocouple connector for K-type sensor5.Temperature Control mode selector switch with MAN/AUTO positions.6.Heaters switches 1 to 6 - ON/OFF switch with internal light. Lights illuminate as each heating element is activated. If theelement is not activated, the switch light will not be illuminated.7.Blower speed controller with OFF and Max provides adjustable airflow settings.8.Temperature Controller Plug (for remote control), remotely displays measured temperature, provides automatic ON/OFFheaters control.Status lights:•POWER - Red light indicates power to the unit is On.•AIRFLOW - Amber light indicates blower is operating and the air flow switch is closed.•SAFETY– Amber light indicates the air flow is safe and the heater internal temperature is below 180° F.HEATER ELEMENTS - Each heating element switch illuminates when switched ON and active.Maintenance of the VulcanThe blower and motor do not require any maintenance when the heater is operated with MERV 11 filter in place. Replace filteras needed. If filter becomes clogged with debris it will reduce the performance of the unit.ALWAYS UNPLUG FROM POWER BEFORE OPENING THE UNIT.ALWAYS FOLLOW YOUR ESTABLISHED HAZMAT PROCEDURES.TroubleshootingThis guide may identify easy to correct problems in Vulcan operation and does not require opening the unit. Only qualified maintenance person should replace internal heater parts. Removable control panel provides easy access to panel mounted components. The heating elements and blower motor can be accessed by removing cover panels on the bottom.Note: Start testing with Temperature Control switch in MAN position.

GS调节阀(COPES-VULCAN)

The SD-Severe Duty valve is SPX’s premium severe duty and critical service control valve design. The SD-Severe Duty line is the next generation of control valves designed specifically for severe duty applications. It is the preferred style of valve for applications such as pump recirculation, feedwater control and feedwater start-up, flashing or cavitating service, critical pressure drop gas and steam service, and any potentially noisy or vibration-prone service. It is also widely used for nuclear “N” stamp and seismic applications.The SD-Severe Duty line incorporates a number of improvements such as:• Quick disconnect between valve stem and actuator yoke on most models that greatly simplifies service and inspection.• An extensive array of standard trims is available including many previously offered only as custom designs.• Shorter lead times/quicker delivery of both entire valve assemblies and replacement parts.Improvements such as these, coupled with SPX’s innovative yet sound engineering practices, and a reputation for building the best control valves possible, assures that the SD-Severe Duty line is destined to become the new industry standard for severe duty and critical service applications.For applications requiring pressure classes of 600 and below refer to Copes-Vulcan’s GS Series valves.D e s cr i pti on an D pr i n ci ple of ope rati onSD-Severe Duty control valve assemblies feature a straight through globe and angle style body design with single web internal construction. The valve body is designed with high structural integrity, large interior flow passageways and a large capacity bowl to accommodate an extensive variety of trim designs while allowing maximum recovery within the valve. The massive amount of body and bonnet material utilized and the thick cross sectional areas allow the SD valve to withstand the most severe operational conditions.The valve is available in sizes .75–20” (20–500mm) and ASME pressure classes 150 through 4500 standard. Larger sizes are available as required. T ypically of cast construction, all standard castable materials are available. When necessary, dueto customer preference or technical requirements, forgings are utilized for both body and bonnet. Depending upon size and pressure class, ends are available as threaded, flanged or welded.The most important sub-assembly of a control valve is the trim. It must control the fluid process, often under extremely high pressure drop conditions, without unduedamage due to flashing, cavitation, wire drawing, noise vibration or instability.4actUal gas e oU s floW tH r oU g H raVe n tr i M.raVe n™ tr i MRaven trim incorporates a unique advanced design that is superbat limiting flowing velocities to low levels resulting in valvesproviding service that is quiet, non-cavitating and non-erosive.Raven’s low velocities are achieved through the use of trim cagemade by bonding together a series of individual discs. Each dischas a pattern of carefully controlled orifices and channels with amultitude of sharp turns etched into its surface. As the trim’s plugtravels within the cage the fluid is throttled and forced to travelan extremely torturous path with each turn effecting a stage ofpressure drop.The combined effect of numerous narrow flow channels, each withmany sharp turns and a continually expanding flow path, removeskinetic energy from the fluid while gradually lowering its pressure.In doing so, abrupt velocity increases that are the source of noiseare avoided. The additional benefit for liquid flow is the eliminationof cavitation and the damage it can do to a valve, its trim and thedownstream piping.By its very design Raven trim allows for many more stages of dropthan conventional torturous path trims.Superior to other velocity control trims, Raven, through the use of aconsistent narrow wall design, typically is more efficient at passingflow or allowing more turns or stages of drop in a given valve size.Most Raven trims contain multiple relief points in the flow path as astandard feature. These relief points allow entrained debris to clearthe main fluid flow, or in the case of significant path blockage, theyprovide an effective bypass route for the fluid. With the benefits ofthe relief points, the actual fluid flow streams still remain virtuallyseparate or discrete from each other for best velocity control.By manufacturing the flow channels to extremely closetolerances, Raven’s calculated or predicted versus actualpressure drops are significantly more accurate thancompetitors. Hence, velocities are more uniform throughoutthe entire trim, further guarding against noise, erosion andcavitation.Ultimately, each Raven trim is specifically designed toprovide the finest severe duty valve service by Reducing andAttenuating Velocity, Erosion and Noise.proven superior technologyNote the highly visible attachment phenomenon wherein the flowstream hugs or clings to each obstruction in its path, effectivelytaking the path of least resistance. Also, despite multiple reliefpoints in the flow path it can be clearly seen that the fluid doesnot recombine with the Raven trim, rather the flow streamsremain virtually separate or discrete from each other for bestvelocity control.45tan D e M tr i MThe T andem Trim is designed primarily for high pressure differential applications where tight shutoff is essential. Such applications include steam and water pressure reduction, steam throttling to atmosphere or to a condenser, isolation, supercritical boiler startup and a variety of other uses in steam and water control systems. Refer to Bulletin 109 for detailed information.gaD™ tr i MThe Port Throttling GAD trim was developed to meet the rigorous requirements of feedwater startup control. Designed to give optimum flexibility in power operated control valves, the trim is available in double seat, balanced single seat, and tandem versions.The GAD trim is equally suitable for use with steam and many other fluids. It has been successfully used on high pressure water applications involving pressure of up to 5075 psi (34970 kPa)and pressure differential of up to 3625 psi (24980 kPa).StemPiston Rings (2)Balancing Chamber Main ValvePilotValveSeat Ring Retainer with Soft SeatStrainerexclU s iVe s oft s eate D H U s H™ tr i M Soft Seated HUSH Trim is designed for new or replacement trim in Copes-Vulcan valves as well as valves of other manufacturers. Any liquid control valve taking a pressure drop up to 5000 psi (34450 kPa) that spends more than 90% of the time in the closed position must use Soft Seated HUSH Trim to maintain zero leakage. Refer to Bulletin 142 for detailed information.HUSH ® Trim is an advanced concept in control valve trim for high presssure-drop liquid, gas and steam applications.It is a cage guided type trim that provides excellent control for compressible and noncompressible fluid applications by directing the flow through a series of staged pressure drops. This unique trim eliminates cavitation in liquid flow and provides multiple pressure breakdown for noise attenuation in critical pressure drop compressible fluide applications.H U s H ® tr i MTrim T ypesA wide variety of trims is available for SD-Severe Duty Control Valves. They are designed to match virtually any severe duty/ critical service operational requirement. All SD trims feature a quick-change design to reduce downtime for inspection, maintenance or change out, and most are cage guided, further ensuring smooth, accurate operation. The majority of the trim line is interchangeable between like sizes, and many reduced trims are also available as standard.6The trims shown in this bulletin represent the more common selections available. Additional standard, special and customengineered trims can be supplied as required.Standard stocked trim materials are 300 series and 400 series stainless steel.

调节阀手册

调节阀手册第一章概述O.P.小洛维特在现代化工厂的自动控制中，调节阀起着十分重要的作用，这些工厂的生产取决于流动着的液体和气体的正确分配和控制。

这些控制无论是能量的交换、压力的降低或者是简单的容器加料，都需要靠某些最终控制元件去完成。

最终控制元件可以认为是自动控制的“体力”。

在调节器的低能量级和执行流动流体控制所需的高能级功能之间，最终控制元件完成了必要的功率放大作用。

调节阀是最终控制元件的最广泛使用的型式。

其他的最终控制元件包括计量泵、调节挡板和百叶窗式挡板（一种蝶阀的变型）、可变斜度的风扇叶片、电流调节装置以及不同于阀门的电动机定位装置。

尽管调节阀得到广泛的使用，调节系统中的其它单元大概都没有像它那样少的维护工作量。

在许多系统中，调节阀经受的工作条件如温度、压力、腐蚀和污染都要比其它部件更为严重，然而，当它控制工艺流体的流动时，它必须令人满意地运行及最少的维修量。

调节阀在管道中起可变阻力的作用。

它改变工艺流体的紊流度或者在层流情况下提供一个压力降，压力降是由改变阀门阻力或"摩擦"所引起的。

这一压力降低过程通常称为“节流”。

对于气体，它接近于等温绝热状态，偏差取决于气体的非理想程度（焦耳一汤姆逊效应）。

在液体的情况下，压力则为紊流或粘滞摩擦所消耗，这两种情况都把压力转化为热能，导致温度略为升高。

常见的控制回路包括三个主要部分，第一部分是敏感元件，它通常是一个变送器。

它是一个能够用来测量被调工艺参数的装置，这类参数如压力、液位或温度。

变送器的输出被送到调节仪表一一调节器，它确定并测量给定值或期望值与工艺参数的实际值之间的偏差，一个接一个地把校正信号送出给最终控制元件一一调节阀。

阀门改奕了流体的流量，使工艺参数达到了期望值。

在气动调节系统中，调节器输出的气动信号可以直接驱动弹簧－薄膜式执行机构或者活塞式执行机构，使阀门动作、在这种情况下，确定阀位所需的能量是由压缩空气提供的，压缩空气应当在室外的设备中加以干燥，以防止冻结，并应净化和过滤。

阀门操作、维护和使用手册说明(阀门投标专用)

阀门储存、操作、维护和使用说明概述阀门是用来关闭和开启管道中介质。

切断阀没有节流的功能。

该类阀门顺时针旋转手轮，直到完全将通道切断，阀门关闭。

逆时针旋转手轮，直到碰到阻挡，阀门打开。

对于电动装置阀门，在断电等紧急情况下，可以使用备用手轮打开和关闭阀门。

注意!截止阀在不超过10%开启状态连续节流会对阀瓣和阀座引起剧烈振动、噪音、磨损和损坏。

止回阀作为控制管道介质单向流动的元件，当介质顺流时由管线自身压力的作用开启阀门，当介质倒流时依靠阀瓣自身重量、弹簧力和介质回流的压力作用在阀瓣背部，使阀瓣与阀座形成密封，达到止回截流的目的。

警告！禁止用夹泵的方式对阀门进行泵验。

2.3 薄膜执行机构的优缺点优点：
结构简单、可靠。缺点：
①膜片承受的压力较低，最大膜室压力不能超过250KPa，加上弹簧要抵消绝大部分的压力，余下的输出力就很小了。
第三十六页，共180页。
②为了提高输出力，通常作法就是增大尺寸，使得执行机构的尺寸和重量变得很大；另一方面，工厂的气源通常是500～ 700KPa，它只用到了250KPa，气压没充分利用，这是不可取的，活塞执行机构解决了此问题。

GSGeneral ServiceControl ValvesGS-General Service Valves The GS-General Service Valves continue Copes-Vulcan’s tradition of designing and manufacturing control valves that provide both exceptional service and great value. Representing significant refinement in design and performance for general service globe style control valves, the GS-General Service Valves combine themost advanced levels of body configuration, trims and actuation to produce a valve assembly capable of premium performance at a competitive price.Suitable for controlling water, steam, gas and most otherfluids, GS-General Service Valves deliver a new standard of versatility, rugged dependability and cost effectiveness that will serve the power and process industries well into the 21 st century.Copes-Vulcan GS-General Service Valves are ideally suited for non-severe flow control of most liquids, steam and gases. They provide reliable, economical performance in heater drains, gas and fuel oil control, feedwater control, steam/gas pressure reduction and many other power and process flow control operations.For applications involving extreme environments, especially hostile fluids, or pressure classes greater than ANSI 600, specify Copes-Vulcan SD-SevereDuty Control Valves.2Description andPrinciple of OperationGS-General Service Valve assemblies feature a straight-through globe style body design with streamlined precisioncast bodies to provide smooth contours and transition areas.The result is minimized flow restriction and maximizedcapacity. Computer calculated cross sections and wallthicknesses assure high structural integrity while maintaininga very favorable strength-to-weight ratio. The GS-GeneralService Valves are available in .75–8” (20–200mm) sizesas standard, ANSI pressure classes of 125–600, and moststandard castable material choices, with either flanged,welded or threaded end connections.GS-General Service Valves can be equipped with an extensivearray of standardized trims to meet virtually any generalservice requirement. A number of high performance trims,such as Raven, HUSH, Tandem, and GAD are also availableand can be used to control occurrences of cavitation,flashing or noise. All trims are quick change to assure easeof maintenance. All trims are fully interchangeable betweenlike sizes to ensure maximum flexibility and reduced inventoryrequirements.A complete range of 700 series pneumatic diaphragmactuators that can handle supply air pressure as high as 80psig (550 kPag) provides performance usually associatedwith much more expensive actuation systems. Copes-Vulcan pneumatic actuators are known worldwide for highperformance and reliability.The design is in accordance with ANSI B16.1, B16.5, B16.11,B16.25, B16.34. Copes-Vulcan also holds the followingcertifications that can be applied to the GS-Style Globe valve:ASME Section I, ASME Section III ‘N’ & ‘NPT’, 97/23/EC-PED-CE and is also ISO-9001 certified.3Trim TypesA broad variety of trims is available for the GS-General Service control valves. They are designed to match virtually anygeneral service operational requirement. All GS trims feature a quick-change design to reduce downtime for inspection, maintenance or change out, and most are cage guided, further ensuring smooth, accurate operation. The entire trim line is interchangeable between like sizes, and many reduced trims are also available as standard offerings. Array* Class VI requires use of soft seat.4The trims shown in this bulletin are a partial representation of the standard trim selection. Additional standard, special and custom trims are available as required.Standard stocked trim materials are 300 series and 400 series stainless steel. Other materials are available as required.* Class VI requires use of soft seat.5Trim Types (Cont.)67ActuatorsSeries 700 actuators are pneumatic diaphragm opera-tors that have spring return in both direct and reverse acting styles, offering fail open and fail closed models respectively. The pressed steel diaphragm case con-struction along with the nylon reinforced Buna-N rubber diaphragm permits a maximum allowable air supply pressure of 80 psig (550 kPag).Series 700 ActuatorThis pre-formed diaphragm provides a constant effec-tive area throughout the full extent of travel.With effective diaphragm areas ranging from 60-160 in 2 (385-1030 cm 2). Series 700 actuators can provide the necessary stem force to meet virtually any operat-ing requirement.Series 700 ActuatorsSeries 800 Manually Operated ActuatorsSeries 500 ActuatorsAn optional top mounted handwheel is available on both direct and reverse acting actuators, permitting manual operation of the valve should a loss in sup-ply air pressure occur. Force is exerted directly on the actuator stem, making manual positioning smooth, easy and precise.The top mounted handwheel will operate the valve in one direction. For direct acting units, the hand-wheel will extend the actuator stem; and for reverse acting units, the stem will be retracted. Side mounted hand-wheels are also available for Series 700 actuators. Contact Copes-Vulcan for details.Copes-Vulcan 500 Series spring opposed diaphragm actuators are designed to provide dependable opera-tion for a wide range of on/off and modulating control valves. This actuator offers many features which are made possible by use of multiple springs about the stem centerline.Refer to Bulletin 500 for details and dimensions.Copes-Vulcan offers handwheel operated actuators for applications where an automated valve is not required or where compressed air service is unavailable. Series 800 actuators are suitable for both on/off and modulat-ing service. Since they are attached to the valve bonnet and stem using the same arrangement as the Series 700, future conversion to an automated actuator canbe accomplished.Series 700 Actuator (Shown with Optional Top-Mounted Handwheel)Reverse Acting (Spring-to-Close)Actuator Size 60100160160LL 21.0653628.0671332.3882240.811037M 11.5029215.1238418.0045718.00 457N 6.50165 6.50165 6.25159 6.38162O 6.7217111.3828911.5629417.19437P10.0025418.0045718.0045718.00457Direct Acting (Spring-to-Open)Actuator Size 60100160160LL 20.5052128.1271432.3182139.751010M11.5029215.1238418.0045718.00 457N 7.561929.382389.3123611.81300O 5.811489.442409.5024115.19386P10.0025418.0045718.0045718.00457GS Valve Body/Bonnet AssemblyFor more information about our worldwide locations, approvals, certifications, and local representatives, please visit our website.Web Site: E-Mail: Copes.Vulcan@5620 West.

Relieve all pressure from the valve and remove it from the system.2. Turn valve stem to full open position.3. Loosen the packing gland locking device.4. While holding the valve body secure, use a torque wrench to tighten the packing gland to the value shown on the attached Installation Summary Chart. If a torque wrenchis not available, tighten the packing gland approximately 1/16 turn.5. Pressurize the valve to the maximum operating pressure and check for leaks.6. If the packing still leaks, relieve all pressure in the valve and repeat steps 4 and 5. If the packing does not seal after several attempts, it needs replaced (refer to Section 3.0).7. Reinstall the packing gland locking device.Section 3.0Packing or Stem Replacement1. Relieve all pressure from the valve and remove it from the system.2. Turn valve stem to full open position.3. Remove the packing gland locking device.Model # Order # Serial # Mfg. DateDrawing #3Parker Autoclave Engineers Instrumentation Products Division Erie, PA USA | Cat. 02-0024ME4. While holding the valve body (or housing for HT and LT valves) secure, unthread and remove the packing gland. The packing will stay on stems that have a larger stem tip below the packing (see Fig. 3: SW8, 10/20SM9, 10/20SM12, 10/20SM16).Note: For HT and LT valves, the housing must be removed where the stem tip is larger than the body cone ring ID (SW6, SM12 and SM16 valves). Remove the housing locking device and unscrew the housing from the valve body.5. Autoclave Engineers manual valves have three different type of stems; one piece non-rotating (figure 2), two piece pinned non-rotating (figure 4) and rotating (figure 5). Follow steps 6-9 for one piece non-rotating stems, steps 10-11 for two piece pinned non-rotating stems andstep 12 for rotating stems.One piece non-rotating stem 6. For stems without a larger stem tip, remove the bottom washer, packing and packing washer in the body. Place the bottom washer, packing and packing washer in the body. If the stem does not require replacement, screw the packing gland back into the body and tighten the packing gland to the value in the Installation Sum- mary Chart.7. Remove the handle by loosening the set screw(s) located in the larger hole of t he handle (use a 5/32 hex wrench for the 3" long handle, a 3/16 hex wrench for the 4" and 10-1/4" long handle) and remove it from the stem sleeve. Unscrew the stem from the packing gland. Remove the two nuts and thrust washer from the top of the stem assembly. Remove the stem from the stem sleeve. Remove the bottom thrust washer from the stem. For SW8, 10SM9 and 20SM9 valves, remove the stem collar by unscrewing it clockwise. For stems with a larger stem tip, remove the packing washer and packingfrom the stem.8.Clean thrust washers and all surfaces which mate with thrust washers with a clean cloth. Apply non-hardening lubricant (Jet-Lube SS-301 or similar) lightly to both faces of the thrust washer and the sleeve threads.9. For stems with a larger stem tip, place the bottom washer, packing and packing washer on the stem (remove the bottom washer from from the old stem if the stem is being replaced). For SW8, 10SM9 and 20SM9 valves, place the stem collar on the stem by threading it counter-clockwise. Place first thrust washer on the stem and slide stem into stem sleeve. Place second thrust washer on the stem sleeve. Replace hex nut lightly against the upper thrust washer and thread the stem assembly fully into the packinggland. Screw the packing gland into the body and tightento the value in the Installation Summary Chart. Open the valve completely, then close it one turn to remove the play. Finger tighten the hex nut, then use a wrench to tighten it approximately 1/8 of a turn. Install the lock nut and finger tighten it in place. While holding the lock nut secure, loosen the hex nut from the top washer and tighten it against the lock nut approximately 1/16 of a turn. Replace the handle by lining the hex socket set screw up against the flat spot on the stem sleeve and tightenit in place (DO NOT OVERTIGHTEN). In order to have a nonrotating stem, a slight amount of free play must exist between the stem sleeve and shaft. The handle should have a 10 degree maximum free play for "backlash". If the free play is excessive, it will be necessary to remove the handle and loosen the lock nut and tighten the hex nut further against the thrust washer. Tighten the lock nut as indicated above and check for free play. When the desired "backlash" is achieved, replace the handle as described above. Re-install the locking device.Two piece pinned non-rotating stems10.

Copes-Vulcan阀门技术解密

Copes-Vulcan阀门技术解密Cascade 隔板节流型阀芯•锥型阀塞上的凹凸槽相当于多级节流板，使流体压降分多级进行，配合锥形的流道及阀座可产生高达200:1的调节比，非常适用于微量控制狭长的密封面使阀门关闭更严密。

•应用场合：减温水；压差较高及汽蚀场合GAD Trim (GAD阀芯)•适用于大流量、大压差的给水控制和给水启动控制。

•细分为三种：双阀座型、平衡单座型级联阀塞型和单级Hush，适用于不同的工况。

Port Throttle Single Seat 窗式节流单阀座•该阀芯为笼套导向型阀芯，通过阀塞的上下运动来改变阀窗的流通面积来实现液体流量和压力的调节。

可以通过改变阀窗的数量来满足不同的工况要求。

•分为平衡型和不平衡型两种。

根据流体温度的不同，平衡型又可细分为普通型和高温型两种。

Port Throttle Tandem Trim 窗式节流双阀芯•主阀塞与导向阀塞以级联方式工作，这样只需要较小的执行机构就可紧密关断，可以满足较大的调节比。

•应用于大压降、关闭严密的地方•蒸汽系统Single Stage Hush 单级降压•减少噪音, 闪蒸, 汽蚀•可调比 35-100:1•线性Hush 多级降压•将单股高能量流体分散成多股小能量的流体，降速降噪，通过孔径错位实现逐级降压，消除汽蚀。

末级套筒使流体沿切线方向离开，不直接面对阀体，减少对阀体的冲刷。

•宏观角度: 将单股高能量流体分散成多股小能量的流体，降速减压；•圆柱型套筒且孔径错位重叠的多级结构分别承担总压降；•计算相邻两级的孔径错位重叠面积,来控制每一级的压降，不让气蚀出现•套筒的级数,套筒的节流孔数,错位面积严格按照工况设计；•流道按一定规律呈螺旋上升排列,在任一个截面上均有流量，具有光滑的流动特性。

工况变化时可以使给水泵“无级变速”，有利于给水泵的正常稳定工作；•每层套筒的节流孔的数量,直径严格按照工况设计；双阀塞双阀座多级Hush降压•给水泵再循环•除了具备Hush阀芯的优点外，通过金属密封（内阀塞和金属阀座）实现节流，软密封（外阀塞和软阀座）实现零泄漏，且内外阀塞联动保证软阀座不被冲刷，保证长期的关闭效果。
