简介
换向阀是具有两种以上流动形式和两个以上油口的方向控制阀。是实现液压油流的沟通、切断和换向，以及压力卸载和顺序动作控制的阀门。可分为手动换向阀、电磁换向阀、电液换向阀等。
工作时借着阀外的驱动传动机构转动驱动轴，带动摇拐臂，启动阀板，使工作流体时而从左入口通向阀的下部出口，时而从右入口变换通向下部出口，实现了周期变换流向的目的。
这种变换阀在石油、化工生产中有着广泛的应用，在合成氨造气系统中最为常用。此外，换向阀还可作成阀瓣式的结构，多用于较小流量的场合。工作时只需转动手轮通过阀瓣来变换工作流体的流向 [1]  。
优点编辑
动作准确、自动化程度高、工作稳定可靠，但需附设驱动和冷却系统，结构较为复杂；阀瓣式结构则较简单，多用于流量较小的生产工艺上。
在石油、化工、矿山和冶金等行业中，六通换向阀是一种重要的流体换向设备。该阀安装在稀油润滑系统输送润滑油的管道中。通过变换密封组件在阀体中的相对，使阀体各通道连通或断开，从而控制流体的换向和启停。
