三通阀的用法

三通阀的用法
三通阀是一种常用的控制阀门，它可以用于实现流体的分流、混合和转向等功能。

具体的用法如下：
1. 分流功能：将一个进口流体分流到两个或多个出口。

在这种情况下，三通阀的一个入口连接到流体源，另外两个出口分别连接到需要分流的管道。

通过调节阀门开度，可以控制流体经过哪个出口流出，实现流量的分配。

2. 混合功能：将两个或多个进口流体混合起来。

在这种情况下，三通阀的两个入口连接到两个不同的流体源，一个出口连接到需要混合的管道。

通过调节阀门开度，可以控制两个流体的混合比例，实现流体的混合功能。

3. 转向功能：用于改变流体的流向。

在这种情况下，三通阀的一个入口连接到流体源，一个出口连接到需求方，另外一个出口不连接任何管路。

通过调节阀门开度，可以控制流体的流向，实现流体流向的转换。

总之，三通阀可以根据不同的需要实现不同的控制功能，广泛应用于液压、气动、化工、能源和工业设备等领域。

1E-mail:*************************23-Way & 4-Way Valves, 2 & 3 PositionGENERAL DESCRIPTIONWafer SealingWafer type elastomer sealingprovides leakproof and low frictionoperation throughout entire pressure range.Versa’s C-Series, C5, C7 & C9, valves are multi-purpose three and four-way, 2 and 3 position, solenoid/pilot, pilot and manually operated pneumatic valves consisting of two body types; side ported and manifold mounted. All the C-Series solenoid valves utilize a high performance solenoid pilot design. This design takes advantage of the available media pressure/force to shift valve assuring positive shifting. A low power solenoid controls the pilot signal which provides the positive force for shifting the valve spool. Solenoid/pilot supply can be either Inpilot or Expilot.Double solenoid/pilot 2 position models feature detented offset positions. Double solenoid/pilot 3 position models feature a spring return to the unactuated center position with all ports blocked or exhaust ports open in the center position or cylinder ports open to inlet.A balanced, packed spool is the flow controlling element of each valve. The balanced spool allows the force necessary to shift the valve to remain independent of the pressure of the medium being controlled. The use of elastomer sealing provides bubble tight operation thus enabling positive positioning of 3 position devices and thrift of operation due to no waste of leaking air.Features: ValveEpoxy molded coilsFor moisture resistance & heat dissipation.Air-Assisted Spring Return Air boosts spring for positive valve return.Anodized Aluminum And Stainless Steel Construction All wetted parts resist damage due to corrosion.ValvesSelector chart, Valves .....................................................................................................................Page 5 Solenoid Operated (side ported and manifold mounte d) ................................................................Page 6 Pilot Operated ................................................................................................................................Page 6-7 Palm button ....................................................................................................................................Page 7-8 Rotary .............................................................................................................................................Page 8-9 Lever ..............................................................................................................................................Page 9-10ElectricalGeneral Purpose Solenoids ...........................................................................................................Page 11 Hazardous Location Solenoids.......................................................................................................Page 12-13 Recommended Hazardous Location Solenoid Option Packages ...................................................Page 14ManifoldsManifold Selector (Plug-In) .............................................................................................................Page 15 Manifold Selector (Rack Mounted) .................................................................................................Page 19 Manifold Accessories (Plug-In) .......................................................................................................Page 16-18 Manifold Accessories (Rack Mounted) ...........................................................................................Page 19Repair kits ...........................................................................................................................................Page 4Specifications .....................................................................................................................................Page 4Dimensions .........................................................................................................................................Page 20012022C SeriesViton SealingProvides superior wear and temperature protection.Life CycleRated for 20 million bubble tight cycles in lubricated service (10 million in non-lubricated service).Balanced SpoolForces required to actuate the valve are unaffected by the controlled pressure.Bubble Tight serviceProvides leak tight sealing reducing cost due to wasted air and positive positioning of actuated device when utilizing 3-position valves.33-WAY VALVE & RACK MOUNT MANIFOLDComplete range of AC & DC voltages.Circuit boardwith integral wiring terminal strip provides fast and easy installation.Junction box doors and screws are captive, reducingthe chance of losing parts, therefore simplifying installation.Plug-InIndicator Lights The indicator light option allows electricalset-up, test and troubleshooting capabilities, simplifying installation.

气动三通阀门使用说明书及维修手册

TFMQ气动阀门（三通）使用说明书及维护手册无锡市中良设备工程有限公司目录一、气动阀门（三通）简图二、气动阀门（三通）的基本结构三、结构性能四、气动阀门（三通）的使用与保养五、故障的检查与维修六、气缸的安装与使用七、气缸的维护与保养二、气动阀门（三通）的基本结构气动三通阀门主要有箱体、翻板、摆杆、气缸、行程开关等组成。

三、结构性能阀门的箱体是阀门的主体，要有足够的刚度和强度，以保证与进料管和出料管的联结和承受自重和物料重，因此由8—10mm厚的钢板焊接而成，同时要保证翻板在其内不受刮、碰影响的翻转，供物料通过。

翻板是关闭和开通物料流量的主要部件，因此要求有足够的刚度、强度和耐磨性，因此选用8--14mm厚的钢板制成，为了保证耐磨性，在阀门体内侧板、翻板两面衬挂耐磨性好的聚氨脂板或65Mn 板，为了降低料流在翻板上的流速，在其上加横档板以降低流速，减少磨损。

四、气动三通阀门的使用与保养气动三通阀门在使用前，首先检查其内部有无异物，卡刮翻板，气源压力应达到额定气压，管路应严密无泄漏，压缩空气应干净，应有过滤器和油雾器，活塞杆、连杆应灵活自如。

连接点螺栓、螺母不得有松动，气缸不得有泄露，检查行程开关控制的位置是否合适，如不正确应调整行程开关的位置。

五、故障的检查与维修见下表：六、气缸的安装和使用要求1、气缸在安装前应首先检查气缸在运输时是否损坏，连接部件是否松动，调整好后再行安装。

2、安装时气缸活塞杆不得承受偏心载荷或横向载荷，应使载荷方向与活塞杆轴线一致。

3、无论采用何种安装型式，都必须保证缸体不变形，气缸的安装底座要有足够的刚度，不允许负载和活塞杆的连接用电焊焊接。

4、气缸水平安置时，特别是长行程气缸，用水平仪进行三点位置（活塞杆全部伸出、中间及全部退回）检验。

5、速度调整，首先将速度控制阀（单向节流阀）的开度放在调整范围的中间位置，随后逐渐调节减压阀的输出压力，当气缸接近预定速度时，即可确定工作压力，最终速度不至撞击气缸盖为宜。

工作条件温度：-25℃~+55℃相对湿度：5%~100%二、工作原理和结构ZJHX/Q气动薄膜三通调节阀由气动薄膜执行机构和三通阀两部份组成。

（如图1）外来的气动信号压力输入薄膜室后，在波纹膜片上产生推力，此力压缩弹簧组，使推杆移动而带动阀杆使阀芯开关，直至推力与弹簧组被压缩后的反力平衡而稳定在某个行程上为止。

依照上述原理，阀芯的行程大小与输入信号压力的大小形成一定的比例关系。

气动多弹簧薄膜执行机构按作用方式可分为正作用式和反作用式两种。

当信号压力增加时，推杆往伸出膜室的方向动作的执行机构为正作用式，型号为ZHA型。

See the valve types table below for the standard variations which are available.Installation• All connections are made with ¼” pipe threadfittings.• Apply a quality thread sealant such as Loctite TM Pipe Sealant to pipe thread connections, but do not permit it to enter the valve passages.• Teflon thread sealing tape may be used butmust be applied so that shreds of the tape donot enter the valve.• Avoid over-tightening fittings on the valve port bosses as they may be cracked, especially when Teflon thread sealing tape is used.• All 4057D/4457A valves may be bracket mounted; most are also suitable for panel mounting.Valve CharacteristicsOperator, finish and thread1 If your operator, finish and thread code does not correspond with the given values, please contact the facility to confirm your operator, finish and thread code.How to OrderOptions• All valves may be bracket mounted; most are also suitable for panel mounting. • A satin chrome nut, part number: 3496L001 is available as an option, and it substitutes for the standard nut to improve the appearance for the front of a panel mounting.• Red knob: part number 681L001 is available for types CA, CB, CD or CE as a substitute for the standard black knob.Valve Characteristics ContinuedSpecification4057D4457AMetric units English units Metric units English unitsBody materialAnodized aluminum Stainless steel Standard spool and internal materials Anodized aluminum Anodized aluminum Standard seal materials Viton Viton Maximum temperature 120°C 248°F 120°C 248°F Flow coefficientKv = 1.04Cv = 1.2Kv = 1.04Cv = 1.2Maximum pressure at ports 1, 2 or 38.62 bar 125 psi 8.62 bar 125 psi Maximum pressure at ports A or B 10.3 bar 150 psi 10.3 bar 150 psiMaximum pressure at port C (types CT & SB ONLY)8.62 bar 125 psi Not available Net weight0.3-0.9 kg 0.6-2 lbs0.8-2.6 kg1.7-5.7 lbs Accreditations availablePEDSuitable for Group 1 & 2 liquids & gases (Ensure materials are compatible)ATEXII 3G TX X4057D Complies with all relevant EU directivesDimensionsType CA: Manual operated - 2.27 kg (5 lbs) force requiredType CB: Manual pull spring return - 6.8 kg (15 lbs) force requiredType CD: Manual or pressure operated manual return - 0.69 bar (10 psi) pressure or 2.72 kg (6 lbs) force required Type CE: Manual or pressure operated spring return - 1.79 bar (26 psi) pressure or 7.26 kg (16 lbs) force required Type CG: Pressure operated spring return - 1.79 bar (26 psi) pressure required2 1/8” (54.0)1 1/16” (27.0)3/4”(19.1)1 1/2” (38.1)1 3/4” (44.5)1 1/32” (26.2)1 1/32” (26.2) 1 1/8” (28.6)9/32” (7.1) DIA2 HOLES4 1/8” (116.1)13/16”(20.6)13/16” (20.6)1 3/8” (34.9)1/2” (12.7)3/8” (9.5)1” (25.4)PANEL OPENING 7/8” (22.2) DIA1/2” (12.7)5/8” (15.9)1” (25.4)ROTATED 90°2 7/8” (73.0)6” (152.4)1 1/8” (28.6)Dimensions - inches (mm)Type CP: Manual latch or pressure operated spring return when released - 1.8 bar (26 psi) pressure required Type CT: Adjustable pressure operated spring return - Adjustable from 0.3 to 1.03 bar (5 to 15 psi) pressure requiredType CF: Double pilot operated - 0.69 bar (10 psi) pressure requiredType C2: Double pilot operated spring return in one direction - 0.69 bar (10 psi) and 1.79 bar (26 psi) pressure required2 7/8” (73.0)7 1/2” (190.5)2 7/8” (73.0)6” (152.4)8 1/4” (210.0)9/16” (14.3)2 9/16” (65.1)6 13/16” (173.0)7/8” (22.0)Dimensions ContinuedType SB: Manual latch or pressure operated spring return when released - 0.9 bar (13 psi) pressure requi red Dimensions - inches (mm)2 1/8”(54.0)3/4”(19.1)1 1/2” (38.1)13/4”(44.5)9/32” (7.1) DIA2 HOLES13/4”(44.5)1”(25.4)1”(25.4)29/16”(65.1)51/2”(140.0)7 5/8”(193.7)9/16”(14.3)11/8”(28.6)11/8”(28.6)3”(76.2)1 1/16”(27.0)Maintenance and Service PartsService kits are available with seals and diaphragm required to service the valve. Order service kits by the service kit model number which is identified by the basic valve model and operator, finish and thread code found in the AMOT valve part number. Refer to the AMOT valve part number printed on the valve nameplate and the AMOT valve part number structure in the how to order section on page 4.Over time, exposure to foreign chemicals and particulate matter as well as prolonged operation at extreme conditions may reduce the effectiveness of the valve. At such time, AMOT Pilot Valves can be restored to original performance simply by installing an AMOT pilot valve service kit. Service kits include all new seals and diaphragm required for normal maintenance.When these valves are used in safety control systems, it is recommended that the system be checked MONTHLY for proper functioning. The unit must be kept clean and free of dust. The end cap is to be regularly inspectedfor signs of damage or rust and replaced if necessary. Ensure that regular inspections of the valve and end cap are carried out to ensure that it is kept clean and free from wear, damage or rust. If the valve shows signs of process fluid leakage, examine the seals. If the valve is subjected to prolonged periods of high vibration at low temperatures, it is possible that wear may occur to the disc assembly and it is recommended that the valve is isolated and safely removed from the system, and returned to AMOT for examination.AMOT designs and tests all its products to ensure that high quality standards are met. For good product life, carefully follow AMOT’s installation and maintenance instructions; failure to do so could result in damage to the equipment being protected or controlled.How to order service kitsService kit model number structure1) Identify the basic valve model, located in the Basic model (A) section of the AMOT valve part number .2) Identify the operator , finish and thread code, located in the Operator , finish and thread (B) section of the AMOT valve part number .3) Use those codes in the service kit identification table below to identify the proper service kit needed to service the valve.
