EVR 40 NC/NO Hot gas defrostingWith hot gas defrosting it is not normally possible to select a valve from condensing temperature t c and evaporating temperature t e .This is because the pressure in the evaporator as a rule quickly rises to a value near that of the condensing pressure. It remains at this value until the defrosting is finished.In most cases therefore, the valve will be selected from condensing temperature t c and pressure drop ?p across the valve, as shown in the example for heat recovery.Heat recovery The following is given: y Refrigerant = R22/R407Cy Evaporating temperature t e = -30 °C y Condensingtemperature t c = 40 °Cy Hot gas temperature ahead of valve t h = 85 °Cy Heat recovery condenser yield Q h = 8 kWThe capacity table for R22/R407C with t c = 40 °C gives the capacity for an EVR 10 as 8.9 kW, when pressure drop ?p is 0.2 bar.The required capacity is calculated as :Q table = f evaporator x f hot_temperature x Q hThe correction factor for t e = -30 °C is given in the table as 0.95.The correction for hot gas temperature t h = 85 °C has been calculated as 4% which corresponds to a factor of 1.04.Q h must be corrected with factors found: With ?p = 0.2 baris Q h = 8.71 x 0.95 x 1.04 = 8.6 kW.With ?p = 0.1 bar, Q h becomes only 6.19 x 0.95 x 1.04 = 6.1 kW.An EVR 6 would also be able to give the required capacity, but with ?p at approx. 1 bar. The EVR 6 is therefore too small.The EVR 15 is so large that it is doubtful whether the necessary ?p of approx. 0.1 bar could be obtained.An EVR 15 would therefore be too large.Result: An EVR 10 is the correct valve for the given conditions.Capacity Suction (continued)Data sheetSolenoid valve, types EVR 2 ? EVR 40 NC/NOR22/R407CAn increase in hot gas temperature t h of 10 K, based on t h = t c +25 °C, reduces valve capacity approx. 2% and vice versa.A change in evaporating temperature t e changes valve capacity; see correction factor table below.Correction factorsWhen sizing valves, the table value mustbe multiplied by a correction factor depending on evaporating temperature t e .Correction factors for evaporating temperature teCapacity Hot gas。

VICKERS电磁阀/威格士电磁阀样本美国威格士原装正品，假一罚十，可以提供报关证明和原产地证明等文件。

美國威格士VICKERS比例压力溢流阀工作时，是利用弹簧的压力来调节、控制液压油的压力大小。

从图3-50中可以看到：当液压油的压力小于工作需要压力时，阀芯被弹簧压在液压油的流入口，当液压油的压力超过其工作允许压力即大于弹簧压力时，阀芯被液压油顶起，液压油流入，从图示方向右侧口流出，回油箱。

液压油的压力越大，阀芯被液压油顶起得越髙，液压油经溢流阀流回油箱的流量越大o如过液压油的压力小于或等于弹簧压力，则阀芯落下，封住液压油进口。

由于油泵输出的液压油压力固定，而工作油缸用液压油的压力总要比油泵输出液压油压力小，所以正常工作时总会有一些液压油从溢流阀处流回油箱，以保持液压油缸的工作压力平衡、正常工作。

由此可见，直动式溢流阀的作用是能够防止液压系统中的液压油压力超出额定负荷，起安全保护作用。

VICKERS比例压力溢流阀和外装附件组成。

其中，主阀包括阀体、压板及膜片、大阀板、缓闭阀板、阀座、阀杆组件等部件。

缓闭阀板用阀杆组件与压板及膜片连接一起，膜片压紧在阀盖与膜片座之间，膜片的上下运动带动缓闭阀板上下升降。

阀杆穿过大阀板的中心孔，因之大阀板可以在一定的范围内沿阀杆滑动。

平时，大阀板在自重压紧在阀座上，使阀门处于关闭状态。

多功能水泵控制阀的外装附件安装在阀门膜片两侧与阀门进、出水管上，膜片的下腔与阀门进水侧的连接管上装设控制阀、过滤器和一只特制的逆止阀。

膜片的上腔与阀门的出水侧的连接管上只设过滤器和一只控制阀。

主阀内大阀板和缓闭阀板的运动和所处的位置决定了阀门工作状态的变化和启闭。

VICKERS电磁阀/威格士电磁阀样本VICKERS电磁阀的主阀按配合形式不同可分为三级同心、二级同心和滑阀式三类。

其中滑阀式结构工作压力低，控制压力精度不高；三级同心结构虽成熟，目前应用较广，但与二级同心式比较，不及二级同心式动作灵敏，规格相同，行程相同时，二级同心结构的通油能力远大于三级同心结构；二级同心式控制压力稳定，加工工艺性好，二级同心式应用前景广阔，这里以二级同心结构，讨论其结构尺寸设计方法。

It remains at this value until the defrosting is finished.In most cases therefore, the valve will be selected from condensing temperature t c and pressure drop ∆p across the valve, as shown in the example for heat recovery.Heat recoveryThe following is given: y Refrigerant = R22/R407Cy Evaporating temperature t e = -30 °C y Condensing temperature t c = 40 °Cy Hot gas temperature ahead of valve t h = 85 °Cy Heat recovery condenser yield Q h = 8 kWThe capacity table for R22/R407C with t c = 40 °C gives the capacity for an EVR 10 as 8.9 kW, when pressure drop ∆p is 0.2 bar.The required capacity is calculated as :Q table = f evaporator x f hot_temperature x Q hThe correction factor for t e = -30 °C is given in the table as 0.95.The correction for hot gas temperature t h = 85 °C has been calculated as 4% which corresponds to a factor of 1.04.Q h must be corrected with factors found: With ∆p = 0.2 baris Q h = 8.71 x 0.95 x 1.04 = 8.6 kW.With ∆p = 0.1 bar, Q h becomes only 6.19 x 0.95 x 1.04 = 6.1 kW.An EVR 6 would also be able to give the required capacity, but with ∆p at approx. 1 bar. The EVR 6 is therefore too small.The EVR 15 is so large that it is doubtful whether the necessary ∆p of approx. 0.1 bar could be obtained.An EVR 15 would therefore be too large.Result: An EVR 10 is the correct valve for the given conditions.Capacity Suction (continued)R22/R407CAn increase in hot gas temperature t h of 10 K, based on t h = t c +25 °C, reduces valve capacity approx. 2% and vice versa.A change in evaporating temperature t e changes valve capacity;

Main valve plateEVR 32 and EVR 40 (NC)EVR 25 (NC)Design (continued)Note :The drawings are only representative.Function EVR solenoid valves are designedon two different principles:1. Direct operation2. Servo operation1. Direct operationEVR 2 – EVR 3 are direct operated. The valves open directly for full flow when the armature (16) moves up into the magnetic field of the coil. This means that the valves operate with a min differential pressure of 0 bar.The valve plate (18) is fitted directly on the armature (16).Inlet pressure acts from above on the armature and the valve plate. Thus, inlet pressure and spring force act to close the valve when the coil is currentless.2. Servo operationEVR 6 – EVR 22 are servo operated with a "floating" diaphragm (80). The pilot orifice (29) of stainless steel is placed in the centre of the diaphragm. The pilot valve plate (18) is fitted directly to the armature (16). When the coil is currentless, the main orifice and pilot orifice are closed. The pilot orifice and main orifice are held closed by the armature spring force and the differential pressure between inlet andoutlet sides.When current is applied to the coil the armature is drawn up into the magnetic field and opens the pilot orifice. This relieves the pressure above the diaphragm, i.e. the space above the diaphragm becomes connected to the outlet side of the valve. The differential pressure between inlet and outlet sides then presses the diaphragm away from the main orifice and opens it for full flow. Therefore a certain minimum differential pressure is necessary to open the valve and keep it open. For EVR 6 – EVR 22 valves this differential pressure is 0.05 bar.When current is switched off, the pilot orifice closes. Via the equalization holes (73) in the diaphragm, the pressure above the diaphragm then rises to the same value as the inlet pressure and the diaphragm closes the main orifice.EVR 25, EVR 32 and EVR 40 are servo operated piston valves. The valves are closed with currentless coil. The servo piston (80) with main valve plate (84) closes against the valve seat (83) by means of the differential pressure between inlet and outlet side of the valve and the force of the compression spring (76). When current to the coil is switched on, the pilot orifice (29) opens. This relieves the pressure on the piston spring side of the valve. The differential pressure will then open the valve. The minimum differential pressure needed for full opening of the valves is 0.2 bar. EVR (NO) has the opposite function to EVR (NC), i.e. it is open with de-energised coil.EVR (NO) is available with servo operation only.Material specifications EVR 2 – EVR 25Note:The drawings are only representative.Material specifications (continued)EVR 32 – EVR 40Note :The drawing is only representative.With DIN plugs coilWith cable connection coilNet weight of coil 10 W: approx. 0.3 kg12 and 20 W: approx. 0.5 kgWith terminal box coilDimensions [mm] and weights [kg]EVR 2 – EVR 6 NC/NO, solder connection For 3D models, visit /products/categories/Note :The drawings are only representative.。

电磁阀选型应遵从的四项原则德国GSR直动式电磁阀现货特价GSR气动调整阀由执行机构和阀体两部分构成。

不同的生产工艺过程对气动调竹阀有不同的功能需求，因此，为实现这些不同的功能，需要在气动调整阀执行机构配置各种附属装置，来充足生产工艺的需求。

如:为实现失去掌控电源后阀门快关或快开，在执行机构气源管线上安装了GSR电磁阀；为使执行机构翰出较大的力矩，在执行机构气源廿线上安装有压力放大器RELAY；为使阀门快速响应、跟踪掌控信号，安装有流量放大器BOOSTER等。

调竹阀是通过调整流过阀门流体的流量，来实现对工艺系统压力、沮度、流量、液位等工艺参数的掌控。

气动调整阀具有结构简单，调整响应快，性能牢靠等优点，因此在电站中得到了广泛应用。

不同生产厂家生产的气动调整阀，其工作原理各有不同，再加各工艺系统对气动阀不同的功能需求，气动阀的种类、工作原理、调试方法、调试项日及方法千变万化、各不相同，因此，有GSR气动调整阀调试过程中，需针对这些不同和差异，对GSR气动阀的调试方法及项日进行相应地删减。

只有了解系统功能需求，把握了气动调整阀的工作原理，才略作到以不变应万变，对调试方法及项目做到心中有数，调试后的气动调怜阀才略实现“手巧”的日的，搭配调整器的“心灵”完成对工艺系统各参数的精、准、快调150 GSR气动调整阀以压缩空气为能源，具有结构简单、动作牢靠、平衡箱出推力大、价格便宜、维护和修理便利等独特的优点，大大优于液动和电动执行器，因此，在核电站中得到了广泛的应用。

GSR德国气动调整阀常用术语介绍:调整器:又叫掌控器，通过使用某些既定的运算来调怜掌控变量的自动操作装置，在闭环调整系统中又叫PID调怜器。

调竹器的翰入接受关于过程变量状态的信息，然后供给一个相庆的愉出信号弹给终端掌控元件。
