电液换向阀

电液换向阀是用控制油路中的压力油推动阀芯，变换流体流动方向的控制阀

电液换向阀是电磁换向阀和液控换向阀的组合，它是用电磁换向阀控制液控换向阀的动作，变换流体流动方向的控制阀。

电液换向阀和液控换向阀主要用在流量超过电磁换向阀正常工作允许范围的液压系统中，对执行元件的动作进行控制，或对油液的流动方向进行控制。

说明事项

1.产品可任意安装，优先考虑水平位置。

2.液压系统所用介质必c须过滤，过滤精度至少20μm。

3.固定螺钉请按样本中所列参数选用。

4.与阀连接的表面，粗糙度要求Ra0.8，平面度要求0.01/100mm

工作原理：。。当两个电磁阀线圈通电时，平衡孔回路关闭，泄流孔回路打开，活塞上腔泄压，活塞上行，阀门打开。反之，活塞下行，阀门关闭。在阀门开启和关闭过程中，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高度上，实现对管道介质流量的控制。

WEH 型阀是一种电动液压驱动的方向滑阀。它控制流的开始、停止和方向。方向阀基本上由带外壳的主阀 (1)、主控制阀芯 (2)、一个或两个复位弹簧 (3.1) 和 (3.2) 以及带有一个或两个回位弹簧的先导控制阀 (4) 组成。螺线管“a”（5.1）和/或“b”（5.2）。

为了正常运行，液压系统必须正确放气。

对于具有 3 个阀芯位置的阀门，主阀中的主控制阀芯 (2) 通过两个弹簧保持在零位或初始位置，对于具有 2 个阀芯位置的阀门，通过加压和弹簧保持在零位或初始位置。在初始位置，两个弹簧腔 (6) 和 (8) 以减压形式通过先导控制阀 (4) 与油箱连接。通过控制管路 (7)，先导控制阀供应先导油。可以在内部或外部（通过端口 X 外部）实现供电。在致动先导控制阀，例如螺线管“a”时，先导控制阀芯 (10) 向左移动，因此弹簧腔 (8) 被先导压力加压。弹簧室 (6) 保持减压状态。先导压力作用在主控制阀芯 (2) 的左侧并使其逆着弹簧 (3.1) 移动。

在关闭电磁阀时，先导控制阀芯 (10) 返回其初始位置（脉冲阀芯除外）。弹簧室 (8) 被卸载到油箱。先导回油在内部（通过通道 T）或外部（通过通道 Y）实现。可选的手动超控 (9) 允许在电磁阀不通电的情况下移动先导控制阀芯 (10)。

阀门的密封性能是指阀门各密封部位阻止介质泄漏的能力，它是阀门重要的技术性能指标。阀门的密封部位有三处：启闭件与阀座两密封面间的接触处；填料与阀杆和填料函的配合处；阀体与阀盖的连接处。其中前一处的泄漏叫做内漏，也就是通常所说的关不严，它将影响阀门截断介质的能力。对于截断阀类来说，内漏是不允许的。
