工作时,阀门与管道主机配合,按照水力过渡过程原理,通过预设的启闭程序,有效消除管路水锤,实现管路的可靠截止,起到保护管路系统安全的作用。
液控止回阀适用于介质为水的泵出口管路上,作为闭路止回阀,用来避免和减少管路系统中介质倒流,防止产生过大的水锤,以保护管路系统。
3)关阀:关阀有三种情况,A:人为关阀;B:水泵或阀门自身故障失电关阀;C:外线失电关阀。不管哪种情况关阀,只需让电磁铁失电即可按预定的程序自动关闭,在电磁铁失电瞬间,电磁力即刻同步消失。电磁锁定轴一旦失去电磁力的作用则即刻开锁,机械锁定轴在失去电磁锁定轴的约束后也即可开锁,此时重锤的势能即重锤杆、举臂、阀轴等零件带动碟板按照预先调定的快关、缓冲、慢关程序作关闭运动,整个过程一气呵成。液控蝶阀在关闭过程中,必须排除举升油缸下腔的油液,据此,采取控制并调节举升油缸排油速度的方法,能有效地对阀门的关闭速度进行控制。液控蝶阀的关闭过程有快关、缓冲、慢关三个程序,其快关时间、慢关时间、快关角度、慢关角度都可以调节。
