水泵控制阀(700X)由主阀、电磁导阀、针阀、球阀、单向阀、行程开关、微形过滤器和压力表组成水力控制接管系统。水泵需停止工作时，先由进口压使主阀关闭90%后，水泵停止运转。剩余10%由回水关闭。可防止水锤现象发生。其工作原理是：当水泵工作阀门向下游供水时，电磁导阀全开，针阀调至适当开度，上游水经针阀、单向阀进入主阀控制室，经电磁导阀流出，此时主阀控制室的压力保持主阀处于合适的开度，保持下游正常供水。当水泵停止工作时，电磁导阀先关闭，主阀控制室停止排水，控制室压力升高，主阀开始关闭。当关闭至90%时，主阀上部行程开关输出停泵信号，水泵停止运转。此时下游回水经单向阀进入主阀控制室，控制室压力升高，主阀被关闭。
