良工阀门集团有限公司浙江温州 325000摘要：高压金属硬密封固定球球阀对密封性具有严格要求，在球阀应用前需要做好密封性分析工作，确保球阀的密封效果。
基于此，本文将从模型简化、边界条件、网格无关性验证、泄漏分析、响应面分析、优化分析六个方面对固定球球阀密封性进行研究，使球阀能够更好地应对压力环境，降低泄漏问题的影响。
关键词：固定球球阀；硬密封；边界条件；泄漏分析引言：球阀操作简单、易于控制的特点，需要具有完善的结构设计，对流体实现有效的密封，使其能够稳定地工作。
球阀通常应用于化工生产环境，因而对密封性具有较高的要求，否则将会对身生产的安全性造成影响。
为此，需要对球阀密封效果进行分析，使球阀的结构更加的完善，进而增强球阀的密封性。
1高压金属硬密封固定球球阀密封原理硬密封固定球球阀需要具有良好的密封性，对阀体泄漏问题进行控制，提高球阀的防漏能力。
球阀泄漏主要由塑性形变现象引起，一旦阀体发生这种形变变化，将会影响接触面之间的闭合作用，导致接触面无法紧密接触，进而导致泄漏现象发生。
阀体、阀座、阀杆等均可发生泄漏问题，需要从密封原理上解决球阀泄漏问题，使球阀结构得到有效地优化。
在球阀内部，主要通过密封环、O型圈对流体进行阻断，当阀门处于闭合状态时，内部压力越大，密封处的闭合效果就会越紧，形成良好的密封作用。
在球阀阀座上装有弹簧，可以对流体的流通产生作用力，受力主要为弹簧受力F和流体压力P。

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.

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 the actuator while in a hazardous location. Removal of the coverwhile 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.11Electric Actuators Performance Rating MAINTENANCE/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.
