E5HP4-TA/EI/40V-D24K1电液换向阀

液压阀是用来控制液压系统中油液的压力、流量和液体流动方向。

二、液压阀的分类

按功能分:

方向控制阀(单向阀、换向阀)

压力控制阀(溢流阀、减压阀、顺序阀、压力继电器)

流量控制阀(节流阀、调速阀)

按操纵方式分:

手动和脚踏、机动、电动、液动、电液动等。

共同点

(1) 在结构上，所有的阀都有阀体、阀芯(转阀或滑阀)和驱使阀芯动作的部件(如弹簧、电磁铁)组成。

(2)在工作原理上，所有阀的开口大小，阀进、出口压差以及流过阀的流量之间的关系都符合孔口流量公式，仅是各种阀控制的参数各不相同而已。

三、对液压阀的基本要求

(1)动作灵敏，使用可靠，工作时冲击和振动小。

(2)油液流过的压力损失小。

(3)密封性能好。

(4)结构紧凑，安装、调整、使用、维护方便，通用性大。

电液阀是由一个主阀和两个电磁阀组成，主阀响应速度的控制是两个柱塞阀，安装于主阀的入口和出口。通过两个柱塞阀细微调节主阀的启闭速度。调整这些装置（柱塞阀）以控制流入和流出活塞上方介质的流量。达到主阀启闭速度能基于介质的粘度及压力调整的目的。

常开（N.O）和常闭（N.C）电磁阀分别安装在主阀的进油回路和出油回路中，用于控制主阀的动作，当两电磁阀通电时，进油孔（上游阀）回路关闭，先导孔（下游阀）回路打开，活塞上腔泄压，活塞上行，主阀打开。反之，活塞下行，主阀关闭。在主阀开启和关闭过程中，可将流量（流速）信号及阀塞位置信号传送给计算机，经过计算机处理后发出相应的指令，控制两个电磁导阀的通、断电状态，使活塞的上下腔的液压差产生变化，从而将活塞控制在所需的开启度上，实现对管道介质流量的控制。

止回阀是指启闭件为圆形阀瓣并靠自身重量及介质压力产生动作来阻断介质倒流的一种阀门。属自动阀类，又称逆止阀、单向阀、回流阀或隔离阀。阀瓣运动方式分为升降式和旋启式。升降式止回阀与截止阀结构类似，仅缺少带动阀瓣的阀杆。介质从进口端(下侧）流入，从出口端（上侧）流出。当进口压力大于阀瓣重量及其流动阻力之和时，阀门被开启。反之，介质倒流时阀门则关闭。旋启式止回阀有一个斜置并能绕轴旋转的阀瓣，工作原理与升降式止回阀相似。止回阀常用作抽水装置的底阀，可以阻止水的回流。
