伺服阀使用说明书
伺服阀使用说明书伺服阀是DEH控制系统中电液转换的关键元件，它可将电调装置发出的控制指令，转变成相应的液压信号，并通过改变进入油动机油缸液流的方向、压力和流量，来达到驱动阀门、控制机组的目的。
1 结构特点伺服阀是一个由力矩马达、两级液压放大及机械反馈所组成的系统。
第一级液压放大是双喷嘴挡板系统；第二级放大是滑阀系统。
其基本结构如图1所示。
1.1 力矩马达：一种电气—机械转换器，可产生与电指令信号成比例的旋转运动，用在伺服阀的输入级。
力矩马达包括电气线圈、极靴和衔铁等组件。
衔铁装在一个薄壁弹簧管上，弹簧管在力矩马达和阀的液压段之间起流体密封作用。
衔铁、挡板和反馈杆刚性固接，并由薄壁弹簧管支撑。
1.2 先导级：挡板从弹簧管中间伸出，置于两个喷嘴端面之间，形成左、右两个可变节流孔。
衔铁的偏转带动挡板，从而可改变两侧喷嘴的开启，使其产生压差，并作用于与该喷嘴相通的滑阀阀芯端部。
1.3 功率放大级：由一滑阀系统控制输出流量。
阀芯在阀套中滑动，阀套上开有环行槽，分别与供油腔P和回油腔T相通。
当滑阀处于“零位”时，阀芯被置于阀套的中位；阀芯上的凸肩恰好将进油口和回油口遮盖住。
当阀芯受力偏离“零位”向任一侧运动时，导致油液从供油腔P流入一控制腔（A或B），从另一控制腔（B或A）流入回油腔T。
阀芯推动反馈杆端部的小球，产生反馈力矩作用在衔铁挡板组件上。
当反馈力矩逐渐等于电磁力矩时，衔铁挡板组件被移回到对中的位置。
于是，阀芯停留在某一位置。
在该位置上，反馈力矩等于输入控制电流产生的电磁力矩，因此，阀芯位置与输入控制电流的大小成正比。
1.4 特点：●衔铁及挡板均工作在中立位置附近,线性好●喷嘴挡板级输出驱动力大●阀芯基本处于浮动状态,不易卡住●阀的性能不受伺服阀中间参数的影响,阀的性能稳定,抗干扰能力强,零点漂移小2 工作原理：当力矩马达没有电信号输入时，衔铁位于极靴气隙中间，平衡永久磁铁的磁性力。
当有欲使调节阀动作的电气信号由伺服放大器输入时，力矩马达的线圈中有电流通过，产生一磁场，在磁场作用下，产生偏转力矩，使衔铁旋转，同时带动与之相连的挡板转动，此挡板伸到两个喷嘴中间。

伺服阀使用说明书
伺服阀使用说明书伺服阀是DEH 控制系统中电液转换的关键元件，它可将电调装置发出的控制指令，转 变成相应的液压信号， 并通过改变进入油动机油缸液流的方向、压力和流量，来达到驱动阀门、控制机组的目的。
1结构特点伺服阀是一个由力矩马达、两级液压放大及机械反馈所组成的系统。
第一级液压放大是 双喷嘴挡板系统；第二级放大是滑阀系统。
其基本结构如图 1所示。
i.i 力矩马达：一种电气一机械转换器，可产生与电指令信号成比例的旋转运动，用在伺服 阀的输入级。
力矩马达包括电气线圈、极靴和衔铁等组件。
衔铁装在一个薄壁弹簧管上，弹 簧管在力矩马达和阀的液压段之间起流体密封作用。
衔铁、挡板和反馈杆刚性固接，并由薄壁弹簧管支撑。
1.2先导级：挡板从弹簧管中间伸出， 置于两个喷嘴端面之间， 形成左、右两个可变节流孔。
衔铁的偏转带动挡板， 从而可改变两侧喷嘴的开启， 使其产生压差，并作用于与该喷嘴相通 的滑阀阀芯端部。
1.3功率放大级：由一滑阀系统控制输出流量。
阀芯在阀套中滑动，阀套上开有环行槽，分 别与供油腔P 和回油腔T 相通。
当滑阀处于“零位”时，阀芯被置于阀套的中位；阀芯上 的凸肩恰好将进油口和回油口遮盖住。
当阀芯受力偏离“零位”向任一侧运动时， 导致油液 从供油腔P 流入一控制腔（A 或B ），从另一控制腔（B 或A ）流入回油腔 T 。
阀芯推动反 馈杆端部的小球，产生反馈力矩作用在衔铁挡板组件上。
当反馈力矩逐渐等于电磁力矩时， 衔铁挡板组件被移回到对中的位置。
于是，阀芯停留在某一位置。
在该位置上，反馈力矩等 于输入控制电流产生的电磁力矩，因此，阀芯位置与输入控制电流的大小成正比。
1.4 特点： 衔铁及挡板均工作在中立位置附近 , 线性好 喷嘴挡板级输出驱动力大 阀芯基本处于浮动状态 , 不易卡住 阀的性能不受伺服阀中间参数的影响 , 阀的性能稳定 , 抗干扰能力强 , 零点漂移小 圃定节流口 F芯阀F駅肝—— 控轴畫的出逵电插2 工作原理：当力矩马达没有电信号输入时，衔铁位于极靴气隙中间，平衡永久磁铁的磁性力。

伺服阀使用说明书
伺服阀使用说明书伺服阀是DEH控制系统中电液转换的关键元件，它可将电调装置发出的控制指令，转变成相应的液压信号，并通过改变进入油动机油缸液流的方向、压力和流量，来达到驱动阀门、控制机组的目的。
1 结构特点伺服阀是一个由力矩马达、两级液压放大及机械反馈所组成的系统。
第一级液压放大是双喷嘴挡板系统；第二级放大是滑阀系统。
其基本结构如图1所示。
图11.1 力矩马达：一种电气—机械转换器，可产生与电指令信号成比例的旋转运动，用在伺服阀的输入级。
力矩马达包括电气线圈、极靴和衔铁等组件。
衔铁装在一个薄壁弹簧管上，弹簧管在力矩马达和阀的液压段之间起流体密封作用。
衔铁、挡板和反馈杆刚性固接，并由薄壁弹簧管支撑。
1.2 先导级：挡板从弹簧管中间伸出，置于两个喷嘴端面之间，形成左、右两个可变节流孔。
衔铁的偏转带动挡板，从而可改变两侧喷嘴的开启，使其产生压差，并作用于与该喷嘴相通的滑阀阀芯端部。
1.3 功率放大级：由一滑阀系统控制输出流量。
阀芯在阀套中滑动，阀套上开有环行槽，分别与供油腔P和回油腔T相通。
当滑阀处于“零位”时，阀芯被置于阀套的中位；阀芯上的凸肩恰好将进油口和回油口遮盖住。
当阀芯受力偏离“零位”向任一侧运动时，导致油液从供油腔P流入一控制腔（A或B），从另一控制腔（B或A）流入回油腔T。
阀芯推动反馈杆端部的小球，产生反馈力矩作用在衔铁挡板组件上。
当反馈力矩逐渐等于电磁力矩时，衔铁挡板组件被移回到对中的位置。
于是，阀芯停留在某一位置。
在该位置上，反馈力矩等于输入控制电流产生的电磁力矩，因此，阀芯位置与输入控制电流的大小成正比。
1.4 特点：●衔铁及挡板均工作在中立位置附近,线性好●喷嘴挡板级输出驱动力大●阀芯基本处于浮动状态,不易卡住●阀的性能不受伺服阀中间参数的影响,阀的性能稳定,抗干扰能力强,零点漂移小2 工作原理：当力矩马达没有电信号输入时，衔铁位于极靴气隙中间，平衡永久磁铁的磁性力。
当有欲使调节阀动作的电气信号由伺服放大器输入时，力矩马达的线圈中有电流通过，产生一磁场，在磁场作用下，产生偏转力矩，使衔铁旋转，同时带动与之相连的挡板转动，此挡板伸到两个喷嘴中间。

WE20梳型阀门规格及安装操作说明书
Series WE20 Butterfly ValveSpecifications - Installation and Operating InstructionsBulletin V-WE20The Series WE20 Butterfly Valve is offered in lug or wafer body styles and is equipped with a PTFE or EPDM liner. The most critical aspect of the Series WE20 Butterfly Valves is the cartridge seat design, which alleviates installation problems associated with common “dove tail design” seats. Valve torques are lower and more consistent as the seat dynamics are not dependent on being coupled between two flanges. Precision machining of the disc and body allow the cartridge design to maintain a tighter disc to seat tolerance, providing a perfect low torque seal each and every time the valve is cycled. The seat to disc seal is independent of flange support and capable of full rated dead end service.Actuators are directly mounted creating a compact assembly for tight spaces. Limit switches are able to be mounted directly to the valves allowing for remote position indication.The Series WE20 can be configured with either an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position or modulating control. Two-position actuators use the supply voltage to drive the valve open or closed, while the modulating actuator accepts a 4-20 mA input for valve positioning. Actuators feature thermal overload protection and permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports, with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve, and internally loaded springs return the valve to the closed position.The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Also available is the SV3 solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion freeservice.WE20-EDA06-LEWE20-CDA04-WP-AA07VALVE DIMENSIONAL DRAWINGWAFER STYLE“WF”LUG STYLE“LT”AUTOMATED VALVE DRAWINGSWafer Valve withPneumatic ActuatorWafer Valve withElectric ActuatorWafer Valve withExplosion-Proof ActuatorLug Valve withPneumatic ActuatorLug Valve withElectric ActuatorLug Valve withExplosion-Proof ActuatorPNEUMATIC ACTUATORNote: For optimal operation, pneumatic actuators should be run with a supply of clean, lubricated air.Spring Return Actuator OperationAir to PORT 2 (the left hand port) causes the actuator to turn counterclockwise (CCW). Loss of air to PORT 2 causes air to exhaust and the actuator turns clockwise (CW). This is the FAIL CLOSE operation.Double Acting Actuators OperationAir to PORT 2 (the left hand port) causes the actuator to turn counterclockwise (CCW). Air to PORT 1 (the right hand port) causes the actuator to turn clockwise (CW).Pneumatic Actuator MaintenanceRoutine maintenance of pneumatic actuator:• Keep the air supply dry and clean• Keep the actuator surface clean and free from dust• Periodic checks should be done to make sure all fittings are tight • P neumatic actuators are supplied with lubrication to last the entire life span ofthe actuator under normal operating conditions. The outer surface of the pneumatic actuator should be clean to avoid friction or corrosion. All fittings and connections should be tight to prevent leaks during operation. Check the bolts mounting the valve to the actuator to make sure they have not come loose during shipping or installation. Make sure the valve and actuator are not rubbing or jamming against other components during operation. The actuator should be inspected annually to make sure all fittings and bolts are tight and nothing has come loose during operation.Disassembling Pneumatic ActuatorsBefore beginning disassembly, ensure that the air supply to the actuator has been disconnected, all accessories have beenremoved, and that the actuator has been disassembled from the valve.1. L oosen the end cap fasteners (23) with a wrench (size varies depending onactuator model). On the spring return actuator, alternate 3 to 5 turns on each fastener until the springs are completely decompressed. Use caution when removing the cap since the springs are under load until the fasteners are fully extended.2. R emove the pinion snap ring (13) with a lock ring tool. The indicator (12) maynow be removed.3. T urn the pinion shaft (2) counter clockwise until the pistons are at the full end oftravel. Disengage the pistons (15) from the pinion. (Note: Low pressure air--3 to 5 psi MAXIMUM--might be required to force the pistons completely from the body.) Note the position of the pistons before removing them from the actuator body. 4. R emove the pinion through the bottom of the actuator. The actuator is nowcompletely disassembled.Be sure the actuator surfaces are free of debris and scratches before reassembling.1. Apply a light film of grease to all O-rings and the pinion before replacing.2. P ut the pinion (2) back through the actuator with the flats of the pinion shaftrunning parallel with the body.3. W hen reassembling the actuator, make sure that the piston racks are square tothe actuator body and returned to their original orientation. (Note: The normal operation of all spring return pneumatic actuators is FAIL CLOSED. To change the orientation to FAIL OPEN, rotate the racks 180º to create a reverse operation.4. W hen replacing springs in a spring return actuator, ensure that the springs arereplaced in their identical position in the end cap from which they were removed. (Note: In some circumstances, you might want to change the standard 80 pound spring set to fit your application and available air pressure.5. Seal the end caps with a petroleum lubricant and bolt to actuator body.6. C heck the seal of the actuator by covering seal areas (pinion, end caps) withsoapy water and using low pressure air to the actuator to ensure that no bubbles are produced.Reassembling Pneumatic ActuatorsWhen working on the Actuator/Valve assembly, disconnect the air or power supply to the actuator. Spring return actuators/valves may change position if power fails or is removed. Never insert any object or body part into the valve body. Severe injury may occur.Pneumatic Actuators Bill of MaterialsELECTRIC ACTUATORSElectric Installation1. Operate valve manually and place in the open position.2. R emove any mechanical stops the valve might have. (DO NOT REMOVE ANYPARTS NECESSARY FOR THE PROPER OPERATION OF THE VALVE, SUCH AS THE PACKING GLAND, PACKING NUT, ETC.)3. E nsure that the actuator output shaft and valve stem are aligned properly. If theyare not, operate the valve manually until they are correct.4. Remove actuator cover.5. B ring power to the actuator. CAUTION: Make sure power is OFF at the mainbox.6. W ire the actuator per the diagram attached to the inside of the cover. Specialactuators (those with positioner boards, etc.) will have diagrams enclosed inside the cover.7. S ecurely tighten bolts used to mount the actuator to a mounting bracket ordirectly to the valve mounting pad if it is ISO5211 compliant.8. C ycle the unit several times and check the open and closed positions of thevalve. Cams are pre-adjusted at the factory; due to the variety of valve designs and types however, slight adjustments might be required.9. Replace cover and tighten screws.To Set The Open Position1. C ycle the valve to the open position by applying power to terminals. The top camand switch control this position. In the open position, the set screw in the top cam will be accessible.2. If the valve is not open completely:A. Slightly loosen the set screw on the top cam.B. R otate the cam clockwise (CW) by hand until the switch makes contact.Contact is made when a slight click can be heard. By making incremental CW movements of the top cam, the valve can be positioned precisely in the desired position.C. When the top cam is set, tighten the set screw securely.3. If the valve opens too far:A. A pply power to terminals. This will begin to rotate valve CW. When valve isfully open and in the exact position desired, remove power from actuator.B. Loosen the set screw in the top cam.C. R otate the top cam counterclockwise (CCW) until the switch arm drops offthe round portion of the cam onto the flat section. A slight click can be heard as the switch changes state.D. Continue applying power to terminals until valve is in the desired position.To Set The Closed Position1. A pply power to terminals to move the valve toward the closed position. Thebottom cam and switch control the closed position. In the closed position, the set screw in the bottom cam will be accessible.2. If the valve is not closed completely:A. Slightly loosen the set screw on the bottom cam.B. R otate the cam counterclockwise (CCW) by hand until the switch makescontact. Contact is made when a slight click can be heard. By making incremental CCW movements of the bottom cam, the valve can be positioned precisely in the desired position.C. When the top cam is set, tighten the set screw securely.3. If the valve closes too far:A. A pply power to terminals. This will begin to rotate valve CCW. When valve isfully closed and in the exact position desired, remove power from actuator.B. Loosen the set screw in the top cam.C. R otate the top cam clockwise (CW) until the switch arm drops off the roundportion of the cam onto the flat section. A slight click can be heard as the switch is no longer making contact with the round part of the cam.D. Continue applying power to terminals until valve is in the desired position.Electric Actuators Wiring Diagram: ACT-TH & ACT-MHWiring Diagrams forTH03-A to TH11-A: 110 VAC, TH03-B to TH11-B: 220 VAC, TH03-C to TH11-C: 24 VACHOTALVE ALVEWiring Diagrams for TH03-D to TH11-D: 24 VDCOPERATION:POWER TO 1 & 2 FOR CCW ROTATION POWER TO 3 & 4 FOR CW ROTATION TERMINALS 5 & 6 FOR FIELD LIGHT INDICATION CONNECTIONSW.#1 SW.#2SWITCH #1 OPEN SWITCH SWITCH #2 CLOSE SWITCHWiring Diagrams forMH03-A to MH11-A: 110 VAC, MH03-B to MH11-B: 220 VAC, MH03-C to MH11-C: 24 VACSW. 1, CLOSESW. 2, OPEN .SW. 3, CLOSE SW. 4, OPEN Wiring Diagrams forMH03-D to MH11-D: 24 VDCSW. 1, CLOSESW. 2, OPEN .SW. 3, CLOSE SW. 4, OPENElectric Actuators Wiring Diagram: ACT-TD & ACT-MDWiring Diagrams forTD02-A to TD07-A: 110 VAC, TD02-B to TD07-B: 220 VAC,TD02-C to TD07-C: 24 VACWiring Diagrams forTD02-D to TD07-D: 24 VDCWiring Diagrams forMD02-A to MD07-A: 110 VAC, MD02-B to MD07-B: 220 VAC,MD02-C to MD07-C: 24 VAC Note: To speed up installation of the control wires to the ACT-MDXX modulating actuator, it is recommended to remove the control module from the actuator. The control module can be removed by removing the two mounting screws on the left and right of the control module. Install the control wires to the correct terminal points and then reinstall the control module.Electric Actuator MaintenanceOnce the actuator has been properly installed, it requires no maintenance. The gear train has been lubricated and in most cases will never be opened.Duty Cycle Definition“Duty Cycle” means the starting frequency.Formula: Running Time ÷ (Running Time + Rest Time) x 100% = duty cycle–> Rest Time = Running Time x (1 - duty cycle) ÷ duty cycleFor example: The running time is 15 seconds30% duty cycle 15 x [(1 - 30%) / 30%] = 35 –> The rest time will be 35 seconds 75% duty cycle 15 x [(1 - 75%) / 75%] = 5 –> The rest time will be 5 seconds If the duty cycle is higher, the rest time will be shortened, which means the starting frequency will be higher.Thermal OverloadAll actuators are equipped with thermal overload protection to guard the motor against damage due to overheating.Mechanical OverloadAll actuators are designed to withstand stall conditions. It is not recommended to subject the unit to repeated stall conditions.Explosion-Proof Electric Actuators1. DO NOT under any circumstances remove the cover of theactuator while in a hazardous location. Removal of the cover while in a hazardous location could cause ignition of hazardous atmospheres.2. D O NOT under any circumstances use an explosion-proof electric actuator in ahazardous location that does not meet the specifications for which the actuator was designed.3. A lways verify that all electrical circuits are de-energized before opening theactuator.4. A lways mount and cycle test the actuator on the valve in a non-hazardouslocation.5. W hen removing the cover, care must be taken not to scratch, scar of deform theflame path of the cover and base of the actuator, since this will negate the NEMA rating of the enclosure.6. W hen replacing the cover, take care that the gasket is in place to assure properclearance after the cover is secured.7. A ll electrical connections must be in accordance with the specifications for whichthe unit is being used.8. S hould the unit ever require maintenance, remove from the hazardous locationbefore attempting to work on the unit. If the actuator is in a critical application, it is advisable to have a standby unit in stock.Electric Actuators Performance RatingMAINTENANCE/REPAIRUpon final installation of the Series WE, only routine maintenance is required. The Series WE is not field serviceable and should be returned if repair is needed. Field repair should not be attempted and may void warranty.WARRANTY/RETURNRefer to “Terms and Conditions of Sale” in our catalog and on our website.

Remove four phillips-head screws from each end section and detach.2. While holding body assembly by the bushings, slide the spool out of the body assembly. Reverse the spool end-for-end and replace it in body assembly.3. Reassemble end sections to opposite ends of body from which they were removed. Tighten screws 1.5 to 2.0 Nm (13 to 18 in-lbs).Internal to External PilotT o operate solenoid valves below their minimum operating pressure, on vacuum, or for dual pressure applications, the valve must be converted to external pilot as follows:1. Remove 1/8" pipe plug and rubber disc from solenoid end(s).2. Remove four phillips-head screws holding solenoid actuating end(s) to body.3. Replace the o-ring with the rubber disc on the exposed end of valve body (disc over thru hole).4. Reassemble solenoid end section(s) to body. Tighten screws 1.5 to 2.0 Nm (13 to 18 in-lbs).5. Attach external pilot supply line(s) (35 PSIG min.) where the 1/8" pipe plug(s) were removed.Service Kits:Valve Seal Kit(Contains all seals found in 3 & 4-Waybodies and all actuator styles) .................................52000 8050 (Fluorocarbon) .........................................................52000 8500Body Service Kit (Contains bushings, springs,retainers and shells for all body styles) ...................52001 8005CAUTION: Foot operated valves must be protected against inadvertent operation that can cause serious bodily injury. Use of a pedal guard is strongly recommended as it will reduce the likelihood of inadvertent operation. If this is not suitable in your application, utilize equivalent protection.Installation & Operating Instructions:Valve should be installed with reasonable accessibility for service whenever possible – repair service kits are available. Keep pipe or tubing lengths to a minimum with inside clean and free of dirt and chips. Pipe joint compound should be used sparingly and applied only to the male pipe, never to the female port. Do not use PTFE tape to seal pipe joints – pieces have a tendency to break off and lodge inside the unit, possibly causing malfunction.Air to the valve must be filtered to realize maximum component life.CAUTION: It is recommended that double solenoid and double remote air pilot operated valves be mounted so that the axis of the valve spool is in the horizontal plane. The valve may be rotated 360° around the axis for mounting convenience.Life Expectancy – Normal multi-million cycle life expectancy of these valves is based on the use of properly filtered air at room temperature.Lubrication – For maximum service life use clean, lubricated air. Valves are shipped pre-lubricated and can be operated without additional lubrication with reduced service life.Recommended Lubricant – Use F442 oil. This oil is specially formulated to provide peak performance and maximum service life from all air operated equipment. Otherwise, use a straight paraffin base mineral oil of viscosity 100-200 SSU @ 100°F and an aniline point greater than 200°F . CAUTION: DO NOT use synthetic, reconstituted, or oils with an alcohol content or detergent additive.CAUTION: This valve shall not be used to actuate a punch press. DO NOT use this valve on punch presses or press brakes. See OSHA 1910.217.Wiring Instructions:Solenoid operators are on the same end as depicted in the ANSI diagrams. Either wire may be “Hot”.NOTE: In addition to above instructions, follow all requirements for localand national electrical codes.Subbase Port Connections:1. Connect inlet air supply to Port 1.2. Connect mufflers (or plumb exhaust) to Ports 3 and 5.3. Connect cylinder Ports 2 and 4 to ends of cylinder or other device to be supplied with air.4. For pilot operated valves connect pilot signal air to Ports 12 and 14.!!!!。

1、入口阀（见图一）入口阀阀体呈直通式，外置活塞式结构和手轮强制关闭系统。
给水从阀座上方一侧引入，从另一侧进入高压加热器，阀上方有两个旁路弯道与止回阀旁路弯道相连接。
阀门有上下两个密封面，高压加热器正常运行时，入口阀开启，阀瓣上浮，与上密封面接触，当高压加热器发生故障时，凝结水则通过快速启闭阀进入活塞上方，使阀瓣下落，关闭阀门。
给水通过两旁路管道直接进入锅炉省煤器，而不经过高压加热器，使高压加热器解列。
入口阀主要由阀体、支架、阀瓣、阀杆、活塞、手轮关闭装置等组成。
阀体有上下两个阀座，下阀座焊在阀体上，上阀座由阀盖通过内套压紧。
阀瓣上下两个密封面均采用硬质合金堆焊而成，阀杆表面经氮化处理，抗擦伤、耐腐蚀。
活塞缸为焊接件，缸体内表面经Ni 基合金镀层处理，有良好的防腐及耐磨性。
活塞由“ O“型环密封，支架起支撑活塞缸及连接阀体的作用。
手轮关闭系统中装有推力球轴承和钢球，使关闭时省力方便。
上部有一螺孔和一焊接法兰，前者为凝结水进口，后者为排除凝结水出口。
阀体下部进出口侧各有一个管接头来连接向高压加热器内注水的管道。
2、止回阀（见图二）止回阀与入口阀一样，阀体呈直通式，有三个进口，一个出口，上部有两个旁路进口与入口阀旁路管相连，下部一端与高压加热器出口相连，另一端为出口，该出口支管与锅炉给水管道相连。
止回阀主要由阀体、阀盖、支架、阀瓣、阀杆等组成。
阀体中镶焊阀座，阀座和阀瓣密封面采用硬质合金堆焊而成，阀杆表面经氮化处理，具有良好的抗擦伤性和耐腐蚀性。
手轮其作用是当高压加热器解列，给水旁路供给锅炉时下阀口应关闭，若阀瓣不下来时需转动手轮，使阀杆向下运动，顶下阀瓣把阀门关闭。

五、主要零件材料
六、使用与安装说明
1、入口阀与止回阀必须垂直安装，阀门与管道焊好后，应清洗干净，清除焊渣与污物。
2、冷凝水通道应为不锈钢材质，在进口处装设过滤网或过滤器。
3、投入使用时，入口阀与止回阀的手轮均应将阀杆旋到最高位置。
4、启动运行的一般步骤如下：
1) 启动时，先操作两阀上的手轮，使阀杆升起，仅留1~2 个丝扣；
2) 开启活塞上下的放气、放水阀，此时缸内有一股来自节流孔板(孔径
一般为φ1.5mm左右)的细流通过。
3) 开启注水阀往管系中注水，当管系内的压力接近或达到给水压力
时，由于面积差而使作用在阀瓣上下的力不同，使阀瓣开启，与上阀座接触并密封,关闭给水通往旁路的通道。
4) 给水通过入口阀进入高加管系内，流经各台高加管系以后流向出口
阀进入省煤器。
5) 高加水侧投入后，关闭注水阀和活塞上的放气阀
6) 缓开抽汽阀投运汽侧，高压加热器投入正常运行。
