电动蝶阀闸阀，再是止回阀，止回阀。最好做弹性支吊架，习惯上顺序为橡胶头，应将橡胶头紧接水泵出口设置，对于闸阀和止回阀还没有个很有说服力的理由决定其顺序。为了防止停泵时产生的水锤对橡胶头产生破坏先是可曲挠橡胶管接头，电动蝶阀

和一般管道安装的阀门和水表用的是同样的子母啊。

建议使用截止阀。要求严格的话，在水泵入口端要有过滤器、关断阀门（截止阀），出口端还要有止回阀。水泵出入口最好有橡胶软接，做*用。

止回阀与PPR管采用两个法兰对夹的连接方式，用螺栓直接将对夹式止回阀及两头管道（带法兰）穿夹在一起。止回阀是指依靠介质本身流动而自动开、闭阀瓣，用来防止介质倒流的阀门，又称逆止阀、单向阀、逆流阀、和背压阀。止回阀属于一种自动阀门，其主要作用是防止介质倒流、防止泵及驱动电动机反转，以及容器介质的泄放。
