换向阀又称克里斯阀，阀门的一种，具有多向可调的通道，可适时改变流体流向。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较为常用。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。

六通换向阀主要由阀体、密封组件、凸轮、阀杆、手柄和阀盖等零部件组成（图1）。阀门由手柄驱动，通过手柄带动阀杆与凸轮旋转，凸轮具有定位驱动与锁定密封组件的开启与关闭功能。手柄逆时针旋转，两组密封组件分别在凸轮的作用下关闭下端的两个通道，上端的两个通道分别与管道装置的进口相通。反之，上端的两个通道关闭，下端两个通道与管道装置的进口相通，实现了不停车换向。
