Series WE06 3-Piece NPT钢球阀值说明书
Series WE06 3-Piece NPT Stainless Steel V-Ball ValveSpecifications - Installation and Operating InstructionsBulletin V-WE06The Series WE06 3-Piece NPT Stainless Steel V-Ball Valve incorporates a V-port ball valve for impressive flow rates with minimal pressure drop. Quarter turn control ball valves are compact, lighter weight and much less expensive than comparable sized globe valves and segmented control valves. They also offer bubble tight shut off with zero leakage and can withstand high pressure drops. The 60° and 90° balls offer an equal percentage flow characteristic. W. E. Anderson’s V-port ball valves have been designed to offer maximum flow characteristics that are substantially higher than comparably sized globe valves. The natural flow pattern of ball valves increases flow rates and in many applications valves smaller than pipeline size can be used. Actuators are directly mounted creating a compact assembly for tight spaces. Limit switches can be mounted directly to the valves allowing for remote position indication. The Series WE06 can be configured with an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position modulating control.Two-position actuators use the supply voltage to drive the valve open or close, while the modulating actuator accepts a 4-20 mA input for valve positioning. Actuators feature thermal overload protection and a 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. 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.WE06-DHD00-TWE06-DDA01-TWE06-DTD01-T-AWE06-DDA01-T-AA01WE06-CTI01-T-AVALVE BILL OF MATERIALSVALVE DIMENSIONAL DRAWINGCv Valve Charts90° V-PORT – Cv60° V-PORT – Cv Pressure/Temperature Rating ChartAUTOMATED VALVE DRAWINGSWITH PNEUMATIC ACTUATORWITH ELECTRIC ACTUATORWITH EXPLOSION-PROOF ELECTRIC 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. I f 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. W hen 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.

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.

弹簧薄膜式减压阀工作原理
弹簧薄膜式减压阀工作原理弹簧薄膜式减压阀，这听起来好像是个高大上的科技名词，其实它在我们的生活中可是扮演着很重要的角色。
想象一下，水管里流出的水，如果没有个好地方把它控制住，那可就乱了套了，哗啦哗啦地喷得满天都是，简直就像是个水龙头发了狂。
不过，有了这个减压阀，事情就完全不一样了，它就像是个守门员，严谨而又可靠，确保水流的压力在一个安全的范围内，避免那些惊险刺激的意外。
这个减压阀究竟是怎么运作的呢？先说说它的结构，里面有一个弹簧和一片薄膜，听起来很简单，但实际上却是个精密的搭配。
弹簧就像是个忠实的守卫，始终保持着一定的压力。
薄膜则负责感应，水流的压力一旦超过了设定的值，薄膜就会被迫移动，像是被惊吓的小猫咪，赶紧回去找它的安全感。
这时候，弹簧会施加力量，帮助薄膜重新归位，保持压力在合理的范围内。
是不是有点儿像猫和弹簧的故事，俩人相互斗智斗勇？说到这里，你可能会想，这样的机制有什么好处呢？大家都知道，控制压力是非常重要的。
如果水流压力太高，管道就可能爆裂，家里的大场面可就闹得天翻地覆，水漫金山。
不过，有了减压阀，咱们就能放心大胆地使用自来水，不用担心这些意外情况。
能有效延长设备的使用寿命，真是一举多得。
还有呢，减压阀在工业领域也是大显身手。
那些大型设备，像是锅炉、压缩机等，都离不开它的保护。
它能让工艺流程更加稳定，减少故障发生的几率，这可不是小事，绝对是企业的“护航神”。
工人们工作时心里也能多一份踏实，别看这小小的阀门，却是整个生产线的重要环节。
减压阀的维护也不可忽视。
毕竟，任何东西都需要照顾，阀门也是一样。
定期检查，确保弹簧和薄膜的状态良好，就像给小车子做保养，不能等到坏了才想起来。
要是有个小故障，及时处理，不然小问题变成大问题，那可真是得不偿失。
说到这里，不禁让我想起了那句老话，预防胜于治疗，真是一针见血！说到减压阀的应用，其实它不止用在水管上，很多地方都能看到它的身影。
像是天然气输送、蒸汽系统，甚至还有一些高科技的实验室设备，都离不开这个小家伙的帮助。

25p先导式薄膜蒸汽减压阀,工作原理
25p先导式薄膜蒸汽减压阀,工作原理
25P先导式薄膜蒸汽减压阀的工作原理是：
通过导阀调节弹簧设定出口压力，导阀薄膜感知出口压力的变化，并反馈动作给主阀，控制其开度，改变节流面积，保持阀后压力稳定。
启动前，导阀弹簧处于自由状态，主阀和导阀处于关闭状态。
当由导阀流入的蒸汽大于由控制孔流出的蒸汽时，主隔膜室中的控制压力增大，打开主阀。
随着蒸汽流过主阀，下游压力的增量经由感应管反馈，作用在导阀膈膜下，平衡隔膜上部的弹簧压力，使导阀逐渐关闭节流，维持主隔膜室中的压力，控制主阀开度输送适量的蒸汽。
以上信息仅供参考，建议查阅先导式薄膜蒸汽减压阀的产品说明书或者咨询相关技术人员，以获取更准确的信息。
