900X紧急关闭阀产品简介
900X紧急关闭阀，是一种用于消防用水与生活用水并联的供水系统中，用来调配水方向的阀门，当火灾发生时，消防急需大量用水，900X紧急关闭阀立即切断生活用水，确保主够的消防用水，当消防停止用水，压力减小时，阀门自动打开，呈现常开状态，恢复生活供水。该阀使系统无需另设专门的消防单独供水管网，大大节约了建设成本和用水量。阀门控制灵敏度高，**可靠，调试简便，使用寿命长。
900X紧急关闭阀工作原理
当主阀出口压力低于导阀设定的压力时，导阀此时处于开通状态，主阀上腔压力与主阀出口压力相等，进口与吃口存在压差，水流经阀口出口流出，当消防泵气泵时，或变平泵压力升高时，超过导阀设定压力，由主阀进口向导阀管控制室压力升高，作用在弹簧压力增大，向下压紧，带动阀芯下移，使导阀关闭，此时主阀进口压力通过节流阀补充到主阀阀盖上腔，因阀瓣受到向下压力大于向上推力，主阀关闭
值得注意的是，进口压力小于设定压力是，主阀处于开启状态，进口压力大于设定压力，阀瓣关闭。
