压力低于进口压力的压力控制阀。
按调节要求不同，有定值减压阀，定差减压阀，定比减压阀。其中定值减压阀应用最广，又简称减压

减压阀由压力先导阀和主阀组成。出口压力油引至主阀芯上腔和先导阀前腔，当出口压力大于减压阀

的调定压力时，先导阀开启，主阀芯上移，减压缝隙关小，减压阀才起减压作用且保证出口压力为定值。

(1)静止状态，减压阀阀口常开，溢流阀阀口常闭;
(2)减压阀控制出口压力稳定，而溢流阀控制进口压力稳定;
(3)减压阀阀口随出口压力的升高而关小，溢流阀阀口随进口压力的升高而开大;
(4)减压阀进出油口都是压力油路，经先导阀的回油必须单独引回油箱，而溢流阀则和出口合并一同流

三、顺序阀
功能顺序阀的功能在于利用液压系统中的压力变化，控制油路通断来控制多个执行元件的顺序动作。
特点按照结构，顺序阀也有直动式和先导式两种。直动式顺序阀结构简单，动作灵敏，但调定压力较

低，较高压力时宜采用先导式顺序阀。根据控制压力来源的不同，顺序阀有内控式和外控式之分，请注意

两者图形符号的区别。内控式顺序阀在进油路压力达到设定压力之前，阀口一直是关闭的，达到设定压力

后阀口打开，使压力油进入油路;外控式顺序阀阀口的开闭与油路进口压力无关，仅取决于控制油路压力的

大小。DGMPC-3-D-ABM-41欢迎您的询价！公司询价联系人：何女士。电话

顺序阀与溢流阀的主要区别为：
(1)顺序阀只有开启和切断两种状态，不象溢流阀那样有自动稳压调节作用;
(2)顺序阀进出油口都是压力油路，所以它的泄油口必须单独引回油箱，而溢流阀则和出口合并一同流

(3)顺序阀的进、出油口一经接通，油液通过该阀的压力损失较小，而溢流阀处于溢流状态时，压力损

失一般较大。

压力继电器是利用液体压力信号控制电气触点通断的液压电气转换元件，当油液的压力达到其设定压

力时，压力继电器发出电信号，以控制电气元件动作，实现执行元件的顺序动作或系统的安全保护和动作

互锁。欢迎您的询价！公司询价联系人：何女士。电话18934630908/15072720048.

按结构特点分为柱塞式、弹簧管式和膜片式。主要零件包括柱塞调节螺帽和电气微动开关。压力油作

用在柱塞下端，液压力直接与弹簧力比较。当液压力大于或等于弹簧力时，柱塞向上移压微动开关触头，

接通或断开电气线路。反之，微动开关触头复位。威格士放大板EEA-PAM-571-A--32
