ZSFS 高压细水雾雨淋控水阀 PistonDelugevalve ZSFS高压细水雾雨淋控水阀组由雨淋控水阀、水力警铃、防复位阀、电磁阀和控制腔供水管路、雨淋报警开启管路、报警管路、排水管路、压力表等部件组成。 高压细水雾雨淋控水阀中有控制腔、供水腔、和管网腔。依靠活塞带动密封封住供水口。控制腔的加压和泄压改变活塞位置，决定雨淋阀的开启或关闭。电磁阀动作或打开紧急手动球阀都可以起动雨淋报警阀。防复位阀的作用是当控制腔泄压雨淋报警阀开启后，封住控制腔进水通道，防止因控制腔增压雨淋报警阀复位断水，在雨淋报警阀关闭时，打开控制腔进水通道补压，防止雨淋报警阀开启造成误喷事故。 ZSFSpistondelugealarmvalvegroupincludesdelugealarmvalve,watermotoralarm,anti-repositionvalve,solenoidvalve,startingpipingofdelugealarmvalve,alarmpiping,drainagepiping,pressuregaugeandetc. Insidethepistondelugealarmvalvetherearecontrolchamber,watersupplychamberandpipenetworkchamber.Thevalvecansealthewaterinletbydependingonthepiston.Theaddingorreleasingpressureofcontrolchambercanchangethepistonposition,todecidetheonoroffofthedelugealarmvalve.Thedelugealarmvalvecanbestartedbybothsolenoidvalvemovementandopentheemergencymanualballvalve.Thepurposeofanti-repositionvalveissealingthewaterinletwayofcontrolchambertoavoidthewaterdisconnectionofdelugealarmvalverepositioncausedbypressureaddingofcontrolvalve,whenthedelugealarmvalveofcontrolchamberpressurereleasinghasbeenopened.Whilethedelugealarmvalveisshutoff,itcanopenthecontrolchamberwaterinlettoaddpressure,inordertoavoidaccidentswhenthedelugealarmvalveisopened.
