性能

(1)调压范围：它是指减压阀输出压力P2的可调范围，在此范围内要求达到规定的精度。调压范围主要与调压弹簧的刚度有关。

(2)压力特性：它是指流量g为定值时，因输入压力波动而引起输出压力波动的特性。输出压力波动越小，减压阀的特性越好。输出压力必须低于输入压力—定值才基本上不随输入压力变化而变化。

(3)流量特性：它是指输入压力—定时，输出压力随输出流量g的变化而变化的持性。当流量g发生变化时，输出压力的变化越小越好。一般输出压力越低，它随输出流量的变化波动就越小

减压阀

减压阀是利用液流流过缝隙产生压力损失，使其出口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。

定值减压阀的结构原理

减压阀起减压作用且保证出口压力为定值的条件是:当出口压力大于减压阀的调定压力，使其先导阀开启。

直动式减压阀

减压阀的功用与特点：

减压阀用在液压系统中获得压力低于系统压力的二次油路上

与溢流阀比较:

减压阀是出口压力控制，保证出口压力为定值;溢流阀是进口压力控制，保证进口压力为定值。

DR 型压力阀是由二次回路控制的先导式减压阀。

减压阀基本上由带主阀芯插件 (3) 的主阀 (1) 和带调节型的先导控制阀 (2) 组成。

在静止位置，阀门打开。液压油从通道 B 通过主阀芯插件 (3) 无限制地流入通道 A。施加到通道 A 的压力作用于下主阀芯侧。同时，压力通过喷嘴 (4) 施加到主阀芯 (3) 的弹簧加载侧，并通过通道 (5) 施加到先导控制阀 (2) 中的球 (6)。它还通过喷嘴 (7)、控制管路 (8)、止回阀 (9) 和喷嘴 (10) 作用于球 (6)。根据弹簧 (11) 的设置，压力会在球 (6) 前面、通道 (5) 和弹簧腔 (12) 中积聚，从而将控制阀芯 (13) 保持在打开位置。通道 B 中的液压流体可以通过主阀芯插件 (3) 不受限制地流向通道 A，直到通道 A 中的压力升高，超过弹簧 (11) 上设置的值并打开球 (6)。控制阀芯 (13) 向关闭方向移动。

当通道 A 中的压力与弹簧 (11) 上设定的压力之间处于平衡状态时，就会实现所需的减压。

先导油从弹簧腔 (14) 返回总是通过控制管路 (15) 从外部进入油箱。

对于从通道 A 到通道 B 的自由回流，可选择安装止回阀 (16)。

压力表连接 (17) 允许控制通道 A 中的减压。

顺序阀

顺序阀是一种利用压力控制阀口通断的压力阀。

按控制油来源不同分内控和外控，按弹簧腔泄漏油引出方式不同分内泄和外泄。

顺序阀的四种控制方式

通过改变上盖或底盖的装配位置可得到内控外泄、内控内泄、外控外泄、外控内泄四种类型。

内控外泄顺序阀

内控外泄顺序阀与溢流阀非常相象:阀口常闭，进口压力控制，但是该

阀出口油液要去工作，所以有单独的泄油口。

内控外泄顺序阀用于多个执行元件顺序动作。其进口压力先要达到阀的调定压力，而出口压力取决于负载。当负载压力高于阀的调定压力时，进口压力等于出口压力，阀口全开;当负载压力低于调定压力时，进口压力等于调定压力，阀的开口一定。
