    500X泄压/持压阀由主阀、泄压/持压导阀针阀、球阀、微形过滤器和压力表组成水力控制接管系统。利用水力自动操作,即可以作泄压阀用又可作持压阀用。 作泄压阀用时,可维持供水路压力在设定的安全值之下;做持压阀用,可维持主阀上游水压在设定值之上,保持主阀上游供水压力。
       本产品利用水力自力控制,不需要其它装置和能源,保养简便,一阀多用。
       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。

SAN、500XXIEYACHIYAFAGONGZUOYUANLI:

   1、作泄压阀:当泄压/持压导阀调整为泄压状态时,水通过针阀、主阀控制室、球阀A、泄压/持压导阀、球阀B流向出口,此时主阀处于开启状态。当进口压力 超过泄压/持压导阀设定的安全值时,泄压导阀会自动开启,通过球阀C放出部分水,使管路泄压。当压力恢复到安全值时,泄压阀自动关闭。作泄压阀时,各球阀 常开。
        2、作持压阀:当泄压/持压导阀调整为持压状态时,只要主阀进口水压低于导阀设定值,导阀即关闭。主要控制室升压,主阀关闭。当主阀上游供水压力超过导阀 设定压力时,持压导阀才能打开,控制室的水经球阀排至出口,控制室降压主阀开启,开始供水,即保持了上游水压。作持压阀用时,球阀C常闭或用丝堵换下。
