4WE6D62/EG24N9K4带电磁操作的三位四通方向滑阀

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。

电磁阀线圈的额定电压有DC12V、DC24V、AC24V（50/60Hz）、AC110V（50/60Hz）、AC220V（50/60Hz）、AC380V（50/60Hz）。一般在电气设计时要么采用AC220V（不需加装开关电源，成本低、线路简单而便于维护）、要么采用DC24V（常用的的安全电压、开关电源/电磁阀线圈都易于维修更换）。

检测电磁阀好坏的方法：先给电磁阀通上被控制的介质（带压力的液体、气体<空气>，压力值为电磁阀使用压力范围的中间值），再给电磁阀线圈通电，如果被控制介质有从通到断或从断到通的状态的变化，那么电磁阀就是好的，否则就是有问题的。

4WE6D62/EG24N9K4带电磁操作的三位四通方向滑阀

产品说明

WE 型号的方向阀为电磁线圈操作的方向滑阀。这些阀控制流体的启动、停止和方向。

这些方向阀主要由壳体 (1)、一个或两个线圈 (2)、控制阀芯 (3) 和一个或两个复位弹簧 (4) 组成。

在断电情况下，控制阀芯 (3) 由复位弹簧 (4) 固定在中心位置或初始位置（脉冲阀芯除外）。控制阀芯 (3) 由液压油 (2) 中带湿式插脚的线圈启动。

要确保正常运行，必须注意将线圈的压力腔注满液压油。

线圈 (2) 的力通过推杆 (5) 作用在控制阀芯 (3) 上并将后者从其静止位置推到所需的终端位置。这可实现 P → A 和 B → T 或 P → B 和 A → T 的必要流向。

线圈 (2) 断电后，复位弹簧 (4) 会将控制阀芯 (3) 推回其静止位置。

手动应急操作 (6) 可在线圈不通电的情况下移动控制阀芯 (3)。

不带弹簧复位“O”（仅可使用符号 A、C 和 D）

这种型号为带两个阀芯位置和两个线圈且不带定位设备的方向阀。在断电情况下，阀芯位置不确定。

不带弹簧复位，带有定位设备“OF”（脉冲阀芯，仅可使用符号 A、C 和 D）

这种型号为带两个阀芯位置、两个线圈和一个定位设备的方向阀。它轮流锁定两个阀芯位置，因此线圈无需较好通电。

注意：

由于设计原因，阀门难免会存在内部泄漏，且泄漏量会随着使用寿命的延长而增加。

弹簧微启式安全阀是利用压缩弹簧的力来平衡作用在阀瓣上的力。螺旋圈形弹簧的压缩量可以通过转动它上面的调整螺母来调节，利用这种结构就可以根据需要校正安全阀的开启(整定)压力。弹簧微启式安全阀结构轻便紧凑，灵敏度也比较高，安装位置不受限制，而且因为对振动的敏感性小，所以可用于移动式的压力容器上。
