一、多功能水泵控制阀结构特点和用途:700X多功能水泵控制阀由主阀、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。二、多功能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。三、多功能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0-801.62.41.762.53.752.75四、多功能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型圈丁腈橡胶阀杆2Cr13弹簧50CrVA针型阀铜合金球阀铜合金浮球阀铜合金*过滤器不锈钢五、多功能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、电磁向导阀六、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多功能水泵控制阀
