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，***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。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。水泵控制阀主要技术参数公称压(Mpa)壳体试验压力(MPa)密封试验压力(MPa)适用介质介质温度(℃)1.01.51.1水0-801.62.41.762.53.752.75水泵控制阀主要零件材料零件名称零件材料阀体阀盖WCB阀座阀盘铜合金密封圈O型圈丁晴橡胶阀杆2Cr13弹簧50CrVA针型阀铜合金球阀铜合金浮球阀铜合金微型过滤器不锈钢水泵控制阀部件列表：1、电器控制开关2、针阀3、球阀4、主阀5、压力表6、单向阀7、电磁向导阀水泵控制阀连接尺寸DNLAA1HH1FDmmD1mmD2mmn-ΦdmmmmmmmmmmmmPN1.0PN1.6PN2.5PN1.0PN1.6PN2.5PN1.0PN1.6PN2.5PN1.0PN1.6PN2.5201802921363422471161051051057575755858564-13.54-13.54-14251802921363422471161151151158585856868654-13.54-13.54-14321802921363422471161401401401001001007878764-17.54-17.54-18402403301553952781701501501501101101128888844-17.54-17.54-1850240330155395278170165165165125125125102102994-17.54-17.54-18652503501654052981801851851851451451451221221184-17.54-17.58-18802853651754303132102002002001601601601331331328-17.58-17.58-181003604101955103502752202202351801801901581581568-17.58-17.58-221254004552205603653102502502702102102201841841848-17.58-17.58-261504554752305854203552852853002402402502122122118-228-228-262005855302556754504603403403602952953102682682748-2212-2212-2625065062330073047050039540542535035537032032033012-2212-2612-3030080070034076049058044546048540041043037037038912-2212-2616-3035086084041584052664050552055546047049043043044816-2216-2616-3340096088043091057071556558062051552555048248250316-2616-3016-364501075930460103061078061564067056558560053255054820-2620-3020-365001075980490113566583067071573062065066058558560920-2620-3320-3660012301060530127072592078084084572577077068568572020-3020-3620-3970016501130560146086598089591096084084087580080082024-3024-3624-428001750123061016409751050101510251085950950990905905928524-3324-3924-48水泵控制阀安装示意图)
