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。

液控的 CVU -**-EPQ 阀，必须由一个单独的比例电磁铁控制的先导阀控制。

这种推荐的先导阀包括在样本中。

规格 3 先导阀带有内置放大器，阀的型号是 KBSDG4V-3，允许与用户的控制三通功能通过闭式过渡特性提供在工作油口 “A” 和进油口 “P” 或出油口 “T”之间（根据阀芯位置）完全可控的节流作用。

在正常工况（即无液压先导压力）阀芯在弹簧作用下给出流道 “A ” 至 “T” ，这可用来作为 “故障保险” 工况。

这些阀供开环和闭环控制系统使用，这里给出的性能数据是当这些阀用于这类系统并采用合适的威格士先导阀和电控器时才具有的。

闭环压力控制主阀芯的零正遮盖工况使 EPQ 阀用于压力控制模式，通过检测压力传感器出油口 “A ” 处的压力使控制回路闭环。

单/双先导控制型式 EPQ 1来自远程先导阀 “A” 口的控制压力是通过安装接口中的 “X” 口，作用在阀芯顶部的整个面积上，阀芯位置则是由输入（指令）信号和 LVD T 位置反馈信号之间的关系来确定。

型式 EPQ 2先导压力除了通过油口 “X”, 还由先导阀的 “B” 口通过三通插装阀中的第二个先导控制口 “B” 连接到阀芯的环状面积，这样阀芯在两个方向的移动都受到先导压力的控制。
