500X泄压持压阀产品简介
500X泄压阀、持压阀主要用于消防或其它供水系统中，以防止系统超压和维持消防供水系统的压力。消防泵关闭后还可以减少水锤的冲击。也用于大型供水系统的水锤消除装置，当给水管路中超过泄压阀设定压力时，泄压阀及时泄压，保护管线安全。也可做持压阀用，保障主阀上游的供水压力。
本产品利用水力自动控制，不需其他装置和能量，保养简单，一阀多用。
本产品广泛用于高层建筑，生活等供水管网以及城市供水管网系统。
500X泄压持压阀产品工作原理
做泄压阀用，当导阀调整泄压阀状态时，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，当进口压力超过导阀设定的安全值时，泄压阀会自动开启，通过球阀C放出部分水，使管路泄压。当管路恢复到安全值时，泄压阀自动关闭，做泄压阀时，各球阀常开。
做持压阀，当导阀调整为持压阀状态时，只要主阀进口水压力低于导阀设定压力值时，导阀即关闭，主阀控制室压力升高，主阀关闭。当主阀上游压力超过主阀设定压力时，主阀才能打开，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，即保护上游水压，做持压阀时，球阀常闭或用丝堵换下。
