700X水泵控制阀产品简介:
700X水泵控制阀由主阀、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。
本产品利用电磁导阀控制,不需要其它装置和能源。节约能源,保养简便,停泵平稳。电磁阀可采用交流电220V或直流电24V。
本系列阀门产品广泛用于高层建筑、生活区等供水管网系统及城市供水工程。
■700X水泵控制阀工作原理:。
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。
