通用阀门计算小软件
化工工艺设计涉及计算的软件介绍
化工工艺设计涉及大量的计算，主要的有工艺流程的模拟，管道水力学计算，公用工程管网计算，换热器设计计算，容器尺寸计算，转动设备的计算和选型，安全阀泄放量和所需口径的计算，火炬泄放系统，控制阀Cv计算和选型，等等。
这些计算过程通常都有专用的商业软件或者是工程公司自行开发的软件或者计算表格。
大的设计公司通常也会指定公司用于以上设计过程的软件或经过确认的表格。
下面就我的经验来看看常用的一些软件。
1.工艺流程模拟：ASPEN PlusPro IIHYSYS2.管道水力学计算通常是工程公司自备的EXCEL表格，没必要使用专用软件。
当然，也可以自己编制，一般来说使用CRANE手册提供的公式就足够了。
两相流的水力学计算相当复杂，自己编制费力不讨好，用公司内部经过验证的表格就可以了。
3.公用工程管网计算我用过Pipe 2000，肯塔基大学教授的出品，包括Gas 2000, Water 2000, Steam 2000等一系列。
Pipenet也是不错的选择。
有人用SimSCI的InPlant。
没用过，有用过的朋友可以介绍一下。
4.换热器设计计算HTRIHTFS这两个软件都可以。
常见的介质用HTRI更好，因为它的物性数据是经过实验得到的。
HTFS使用了ASPEN或HYSYS的物性数据，很多都是计算得到的，所以精度可能稍差。
5.压力容器尺寸计算（长度与内径）工程公司往往使用自制的EXCEL表格来计算容器尺寸。
内构件一般要提交供货商来设计。
计算容器尺寸首先要确定容器的用途：气液分离，液液分离，还是气液液三相分离。
然后要确定容器是卧式还是立式。
最后要根据物料属性，考虑是否使用Wire Mesh或其他内构件来除去微小雾滴。
以上三项是影响计算的主要因素。
6.塔设备计算塔设备的计算和内构件的计算通常要由主要的供货商来进行。
软件比如说Koch-Glitsch的KG-Tower和Sulzer 的SULCOL。
工程公司一般只提供过程模拟的结果。

It is important that you analyze all aspects of your application, including consequences of any failure, and review the information concerning the product or system in the current product catalog. Due to the variety of operating conditions and applications for these products or systems, the user, through its own analysis and testing, is solely responsible for making the final selection of the products and systems and assuring that all performance, safety and warning requirements of the application are met.The products described herein, including without limitation, product features, specifications, designs, availability and pricing, are subject to change by Parker Hannifin Corporation and its subsidiaries at any time without notice.Carefully read installation, operation and maintenance procedures prior to installing or servicing valve.Do not use valve as a safety shut-off valve when making repairs. Do not install a valve before depressurizing system down to atmospheric pressure.Care must be taken to ensure that the valve materials selected are suitable for the media being handled. Parker assumes no liability for damage caused by improper material selection.Caution: Do not, at any time, make any alteration or modifications to any valve without the express and written approval of Parker’s Fluid Control Division.DESCRIPTIONThese valves are 3-way direct operated valves. The 304 series valve product line are available as Normally Closed (N.C.), Normally Open (N.O.), or universal (U) valves. The direct acting valves operate with zero pressure differential.Valves may be ordered with either NEMA 2, 4, 4X integrated coils for ordinary locations. Additional solenoid coils and enclosures are offered as described in our catalog.FLUID CODESListed below are the common fluid codes. The codes for the approved fluids for use with each valve are printed on the outside of the individual packaging.CODE FLUIDA - Air or nontoxic, nonflammable gasesAC - AcetyleneG - City gas supplied by public utilieisGA - GasolineHO - Petroleum based oils having viscosities up to 400SSU at 38°F02 No1 and No 2 fuel oils with viscosities lessthan 40SSU at 38°COX - OxygenW Water or other aqueous nonflammable liquidsFor the maximum fluid temperatures, as well asvalve ambientlimitations, check the valve part number on the nameplate and refer to the catalog.TORQUE CHARTINSTALLATION INSTRUCTIONS Installation must be done according to all applicable Safety Codes and Standards and by qualified personnel.Inspect valve prior to installation. Damaged valves oractuators must not be installed.Mounting position and pressure limits: Valves can bemounted directly on piping or by using the two #8-32 UNF threaded holes in the bottom of the valve body for the 1/8” NPT valves. Two #10-32 UNF threaded holes for the 1/4” NPT valves. The valves are designed to operate in any position. The valve may be installed in any line regardless of the direction in which the line runs. However, for optimum life and performance, the valve should be mounted vertically upright so as to minimize wear and reduce the possibility of foreign matter accumulating inside the sleeve area. Line pressure, voltage and frequency must conform to nameplate rating. Allow adequate clearance above valve for removal of coil. WARNING: Do not install a valve whose permitted pressure / temperature ratings are inadequate to meet the operating conditions. Piping: Remove protective closures from the ports. Connect line pressure to the inlet port and apparatus piping to the outlet port. Use of Teflon™ tape, threaded coumpounds or sealants is permissible but should be applied sparingly to male pipe threads only. CAUTION : Do not allow foreign particles, Teflon tape, or thread compound to enter valve. Only the wrench flats provided on the body ports should be used in applying the torque. Ports should not be subjected to excessive torque by use of an oversized wrench, wrench extension or by impacting the wrench handle. Do not use the valve to “stretch” or “align” the pipe. Tightening torque should not exceed 100 in-lbs for 1/8” NPT valves and 175 in-lbs [20,0 Nm] for 1/4” NPT valves. Do not use sleeve or enclosure as a lever when applying torque.Media filtration: For protection of the valve, install a suitable strainer or filter in the inlet side as close to the valve as possible. Dirt or foreign material in the media may cause excessive leakage, wear, or in exceptionalcases, malfunction. Clean periodically depending on service conditions. Lubrication: Lubrication is not required although air linelubrication will substantially increase valve life. Electrical connection: Electrical supply must conform to nameplate rating. Connect coil leads or terminals to the electrical circuit using standard electrical practices in compliance with local authorities and the National Electrical Code. Do not power coil until it has been fitted over sleeve and the retaining nut has been installed to prevent possible coil damage from overheating. WARNING : Turn off electrical power before connecting the valve to the power source. If the coil assembly is located in an inconvenient orientation, it may be reoriented to facilitate installation. Loosen coil assembly nut, rotate coil assembly to desired position, then retighten the retaining nut with an input torque per chart. COIL ASSEMBLY Position coil (as described below) on the sleeve, position and tighten retaining nut into the top of the sleeve assembly using a 5/32” or 5mm hex wrench with an input torque per chart. If the coil orientation needs to be repositioned to meet installation wiring needs, simple loosen the retaining nut usi ng a 5/32” or 5mm hex wrench , then rotate the coil to the required position and tighten the retaining nut. NOTE : The one-piece integrated coil assembly contains top and bottom o-ring seals to prevent moisture ingressioninto the sleeve area. The o-ring seals must be installed correctly for proper functionality. PORT MARKING ARRANGEMENTDe-Energized Energized11 33333One-Piece Integrated Coil. The conduit coil meets NEMA 2, 4, 4X classification for ordinary location requirements. Use suitable electrical cabling and conduit materials and components meeting applicable NEMA recommendations.For both the conduit and leaded one-piece coils, slide one o-ring over and down the sleeve assembly until the o-ring rests on the valve body., Slide the coil over the valve sleeve. Place the second o-ring into the recess located on top of the coil. Affix retaining nut to sleeve and tighten per torque chart. Use suitable electrical cabling for wiring connection.WARNING: Both the conduit coil and leaded one-piece coil contain a green “grounding” wire that must be secured to a proper ground location. The grounding wire is welded to the internal coil frame providing the approved ground path for the total valve assembly.DO NOT cut off the green ground wire. Doing so could negate a proper ground path and leave the valve assembly unprotected or “hot”.One-Piece DIN Coil and various cable option terminations:Loosen cable screw and remove plastic housing from DIN coil. Do not remove the gasket from the DIN spades on the coil. Separate the plastic block from the housing with a small screwdriver to expose the elecctrical terminations. Feed the lead wires through the conduit hub and attach them to the appropriate screw terminal. For electrical connection within the terminal box, use field wire that is rated for 90o C or greater. Snap the plastic block back into place inside the metal enclosure. Replace the cover and hand-tighten the cover screws. Place the gasket over the DIN spades on the coil and press the terminal box and coil together. Secure the terminal box to the coil using the mounting screw provided.Slide one o-ring over and down the sleeve assembly until the o-ring rests on the valve body. Slide the DIN coil over the valve sleeve. Place the second o-ring into the recess located on top of the coil. Affix retaining nut to sleeve and tighten per torque chart.Two-Piece Yoke & Spade Coil with 1/4” tabs: With coil inserted inside of U-shaped metal yoke, slide coil over sleeve.

Two Piece Grommet Housing & Taped 2 Wire Coil: With the taped coil inserted inside the metallic housing, slide coil over sleeve. Affix retaining nut to sleeve and tighten per torque chart. Use suitable electrical cabling for wiring connection.Coil/enclosure temperature:The direct acting valves are supplied with coils designed for continuous duty service. Normal free space must be provided for proper ventilation. When the coil is energized continuously for long periods of time, the coil assembly will become hot. The coil is designed to operate permanently under these conditions. Any excessive heating will be indicated by smoking and/or odor of burning coil insulation.For the maximum valve ambient conditions, as well as the fluid temperatures, check the valve part number on the nameplate and refer to the product catalog to determine the maximum temperatures.MAINTENANCENote: While the valves are design to operate over millions of cycles, depending on service conditions, fluid being used, filtration, and lubrication, it may be required to periodically clean and/or replace worn components to ensure optimum quality performance. See Disassembly Instructions.CAUTION:Do not expose plastic or elastomeric materials to any type of commercial cleaning fluid. Parts should be cleaned with a mild soap and water solution.If a valve is to be removed from a pipeline carrying hazardous media, the parts of the valve in contact with the hazardous media must be properly cleaned and decontaminated before repairs are performed.DISASSEMBLY INSTRUCTIONSWARNING:Depressurize system and turn off electrical power to the valve before attempting repair. The coil must not be energized unless it is installed on the valve. Otherwise, the coil will overheat and burn out.The valve body need not be removed from the line.CAUTION:When removing or replacing the sleeve assembly, it may be necessary to provide proper support to prevent the valve from rotating thereby causing damage to piping.To remove the coil assembly:Using a 5/32” or 5mm hex wrench, unscrew the top retaining nut of the coil assembly. The coil assembly can be lifted off the sleeve tube.To disassemble the pressure vessel:Use the same 5/32” or 5mm hex wrench turning counterclockwise to remove the sleeve tube.

音标通用阀门标准
音标通用阀门标准一、前言嘿，今天咱们来唠唠音标通用阀门标准这个事儿。
你看啊，在工业领域里，阀门那可是相当重要的部件，就像人体里的血管开关一样。
不管是石油化工行业，还是给排水系统，或者是供热供暖方面，阀门都起着控制流量、压力等关键作用。
但是呢，如果没有一个统一的标准，那就乱套啦。
各个厂家生产的阀门规格不一、质量参差不齐，这在安装、维修和替换的时候就会带来很多麻烦。
所以音标通用阀门标准就应运而生了，它就像是一把尺子，用来衡量阀门是否合格，让整个阀门市场更加规范有序。
二、适用范围（一）工业管道系统在大型的工业管道系统里，音标通用阀门标准可是非常实用的。
比如说炼油厂，那里有大量的原油、成品油在管道里流动。
不同的生产流程需要不同类型的阀门来控制。
按照音标通用阀门标准生产的阀门，就能很好地适配这些管道。
例如，在原油输送管道上的截止阀，必须满足这个标准里对于抗压能力、密封性能等方面的要求，这样才能保证原油在管道里安全、稳定地流动，不会出现泄漏或者堵塞的情况。
（二）建筑给排水系统咱们住的房子里也离不开阀门。
从自来水的入户管到卫生间、厨房的各种用水设备，都有阀门在默默工作。
音标通用阀门标准在这里也同样适用。
像家里马桶水箱下面的角阀，如果不符合这个标准，可能就会出现漏水的情况，不仅浪费水，还可能把家里的地板泡坏呢。
而且在整栋建筑物的给排水主管道上，大口径的闸阀或者蝶阀也得遵循这个标准，这样物业在进行维护和管理的时候才方便，不然光是判断阀门有没有问题就得费好大劲儿。
（三）暖通空调系统再说说暖通空调系统吧。
暖气管道里热水的循环、空调制冷管道里制冷剂的流动，都需要阀门来调节。
音标通用阀门标准能确保这些阀门在温度变化、压力波动等情况下正常工作。
比如在北方的集中供暖系统中，小区换热站里的调节阀如果不符合标准，就可能导致某些住户家里暖气不热或者过热，这可关系到大家冬天的舒适度呢。
三、术语定义（一）公称通径这就好比是阀门的一个“身份证号码”，是用来表示阀门规格大小的一个数值。

化工工程计算安全阀泄放面积计算帮助文档API易算云科技
易算云安全阀的设计计算API 520 —20231. 易算云计算软件简介安全阀是容器安全泄放装置的一种，重要配备于压力容器上，应对容器也许出现的超压情况。
安全阀一般由弹簧作用，当入口处静压超过其设定压力时，阀瓣上升以泄放被保护系统的超压。
本计算合用于安装单个泄放装置，不涉及两相流泄放。
2. 易算云计算软件参考标准API 520, Sizing, Selection, and Installation of Pressure-relieving Devices API 521, Pressure-relieving and Depressuring SystemsAPI 526, Flanged Steel Pressure-relief Valves3. 易算云计算过程3.1 安全阀设定压力安全阀设定压力（P S）系指，当安全阀入口处的静压达成该值时，安全阀将动作。
安全阀保护的系统内有也许存在两个以上的压力设备，再考虑到其中的管道和阀门，安全阀的设定压力规定不大于被保护系统内的最低设计压力。
此外，若已知设备或管道的最高允许工作压力（Maximum Allowable Working Pressure, MAWP），可用最高允许工作压力来替代设计压力。
3.2 允许超压与泄放压力超压指超过泄压装置设定压力的压力，在压力泄放装置排放期间，允许容器内压力超过容器的最大允许工作压力（或者是设计压力），该压力的增值即是允许超压（Accum%），通常用百分数来表达。
依据API 520之规定，对于单阀泄放系统而言，火灾事故工况的允许超压为21%，其他为10%。
泄放压力（P1）系指安全阀阀芯升到最大高度后，阀入口处的压力。
泄放压力等于设定压力加允许超压。
P1= P S X (1 + Accum%) (1) 对于单阀泄压系统，安全阀与容器有关的压力如下：表1 安全阀与容器的压力关系表 1 表白了不同情况下，被保护系统设立安全阀的最大泄放压力、最大设定压力与被保护系统的最低设计压力之间的数值关系。

For solenoid operated 3-position valves, the gasket between the pilot body and the adapter is a custom molded shape. For remote air operated 3-position valves there is no adapter and the gasket provided may be discarded. (See Illustration #1 for the correct gasket.) For custom molded shapes, the seal should be lightly pressed into the gasket track, pushing knob projections into operator slot.7.Apply a light film of grease to operator piston bores and all surfaces ofpiston seals. Install seals to piston with the lips of the seals facing away from the piston end where the nose enters into the main valve body bore. Install the piston/seal assemblies into the operator bores,taking care to assure the lips of the seals pass smoothly onto the bores. For solenoid operated valves, take care to assure the spring (Item #23) enters the pocket of the molded shape in the mechanism.Refer to illustration for proper part orientation. (If the spring (Item #23)was removed from the poppet seal, it should be reinstalled with the end with more tightly wound coils against the poppet seal.)8.Reassemble the operators to the main valve body using two (2) screwsfor each operator, assuring the operator is on the same end as before.Assure the sides of solenoid pilot bodies with the manual override hole, and the sides of air pilot operators with ports are on the same side of the main valve body as the ports marked #2 and #4. Tighten the screws to 12 inch-pounds torque. (If the solenoid has been removed,reassemble the solenoid components in their original orientation. The solenoid to pilot body o-ring should be assembled into the solenoid coil counterbore. The solenoid screws should be tightened to 6-8 inch-pounds torque. For more complete information on disassembly and reassembly of solenoid components, refer to instruction sheet V373P .)9.Turn on air pressure and electrical power source.

调节阀选型计算软件 调节阀计算 选型 使用
调节阀选型计算软件调节阀计算选型使用导读：就爱阅读网友为您分享以下“调节阀计算选型使用”的资讯，希望对您有所帮助，感谢您对92to 的支持! 定位器工作不正常，其气路节流口堵塞是最常见的故障。
因此，带定位器工作时，必须处理好气源，通常采用的办法是在定位器前气源管线上安装空气过滤减压阀。
4）增大节流间隙法如介质中的固体颗粒或管道中被冲刷掉的焊渣和锈物等因过不了节流口造成堵塞、卡住等故障，可改用节流间隙大的节流件—节流面积为开窗、开口类的阀芯、套筒，因其节流面积集中而不是圆周分布的，故障就能很容易地被排除。
如果是单、双座阀就可将柱塞形阀芯改为“V”形口的阀芯，或改成套筒阀等。
例如某化工厂有一台双座阀经常卡住，推荐改用套筒阀后，问题马上得到解决。
5）介质冲刷法利用介质自身的冲刷能量，冲刷和带走易沉淀、易堵塞的东西，从而提高阀的防堵功能。
常见的方法有：①改作流闭型使用；②采用流线型阀体；③将节流口置于冲刷最厉害处，采用此法要注意提高节流件材料的耐冲蚀能力。
6）直通改为角形法直通为倒S流动，流路复杂，上、下容腔死区多，为介质的沉淀提供了地方。
角形连接，介质犹如流过90℃弯头，冲刷性能好，死区小，易设计成流线形。
因此，使用直通的调节阀产生轻微堵塞时可改成角形阀使用。
4.3 密封性能差的解决方法（5种方法）1）研磨法细的研磨，消除痕迹，减小或消除密封间隙，提高密封面的光洁度，以提高密封性能。
2）利用不平衡力增加密封比压法执行机构对阀芯产生的密封压力一定,不平衡力对阀芯产生顶开趋势时,阀芯的密封力为两力相减,反之,对阀芯产生压闭趋势,阀芯的密封力为两力相加，这样就大大地增加了密封比压,密封效果可以比前者提高5～10倍以上.一般dg≥20的单密封类阀为前一种情况,通常为流开型,若认为密封效果不满意时,改为流闭型,密封性能将成倍增加.尤其是两位型的切断调节阀,一般均应按流闭型使用。
3）提高执行机构密封力法提高执行机构对阀芯的密封力，也是保证阀关闭，增加密封比压，提高密封性能的常见方法。

通用型FPSO阀门选型及分类方法
通用型FPSO阀门选型及分类方法徐江果;徐健【摘要】FPSO阀门结构类型、材料防腐耐久性能、生产质量等都会影响阀门的使用寿命.针对FPSO管路系统特点,分析该船型常用阀门和分类方法,将阀门信息汇集成通用阀门数据表集,方便相同船型项目中阀门的快速、准确选用设计.【期刊名称】《中国海洋平台》【年(卷),期】2019(034)004【总页数】8页(P93-100)【关键词】阀门选型;标准化;VBA;阀门数据表集【作者】徐江果;徐健【作者单位】上海外高桥造船有限公司,上海200137;上海外高桥造船有限公司,上海200137【正文语种】中文【中图分类】TE9730 引言在海洋油气开发工程中，FPSO以其生产系统投产快、投资低、承重能力和抗恶劣环境能力强、储油能力大、应用灵活、移动方便等优势被广泛使用。
出于经济性考虑，FPSO通常长期服役于深海进行不间断生产。
一般FPSO的设计使用寿命为25 a，对防腐耐久性措施要求十分严格。
由于FPSO集油气生产、储存外输、生活起居等众多功能于一身，其管线系统众多，阀门作为全船流体输送系统的控制部件，是管网的关键组成部分，对FPSO阀门的要求远高于普通船舶，选型正确与否直接影响系统可靠性。
因此，阀门的选型设计应在设计标准、结构形式、材料等各个方面作全面的考量，对阀门进行细致、科学的分类，以便在相同船型项目中进行阀门的快速、准确选用设计。
目前在FPSO上使用的阀门产地众多，生产质量参差不齐，虽然有阀门设计标准和各类国际规定作为约束，但仍存在一定的弹性空间，导致相同船型的阀门质量良莠不齐。
本文细化阀门数据表，从设计源头对阀门生产质量作清晰的要求，保证阀门质量符合FPSO的使用要求。
