换向阀
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。
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。
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,时而人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。
阀板式的优点是动作准确、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。
