VICKERS电磁阀威格士电磁阀样本

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。

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。
