一、DY30BX缓开快闭止回阀概述:缓开快闭止回阀它包括阀体内设阀座、阀杆、以及与阀体连接的上阀盖与下阀盖等零件组成。上阀盖与下阀盖之间为隔膜腔,隔膜腔内设隔膜,隔膜与中心轴连接,中心轴另一端连接阀门,阀门与阀座接触。水容器与上阀盖进水、出水控制孔连通,水容器与上阀盖出水为节流连通,水容器与上阀盖进水为单向连通。该阀缓慢开启,防止电流冲击及官网中压力冲击;快速关闭,防止水锤产生。无水质要求,可用于污水、清水及原水系统。产品特点缓开快闭止回阀采用双室驱动装置,Y型结构。介质在定向运动中具有半直线水流,过流量最大,压力损失小,启闭运行平稳、不产生压力波动等优点。双室驱动装置可作为一个整体拆卸,便于检查,膜片采用尼龙强化橡胶制成,合用寿命长,阀瓣密封件可拆卸,维修更方便缓开快闭止回阀工作原理缓开快闭止回阀安装在系统管线上或泵出口端,正常运行中,进口端介质推动大阀盘上移,同时介质通过流量控制器进入中腔,使阀门速度打开,停止运行,出口端介质通过调节阀进入上腔,使驱动装置下移带动大、小阀盘向下运动,快速或缓慢关闭阀门,防止介质倒流。注意事项1、系统运行前应检查主阀上导阀、配管、管件是否严密完整无损2、导阀及配管上的控制阀动作是否正常3、系统运行一段时间后要进行管路维护调节方法1、打开截止阀2、启泵观察阀门进口压力是否正常3、停泵观察水锤是否过大,水泵是否倒转4、如水锤过大则适当关小截止阀5、如水泵倒转则适当开大截止阀缓开快闭止回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缓开快闭止回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缓开快闭止回阀主要连接尺寸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)
