E cB When someone receives a green card in the United States, then they must spend enough time in the country to demonstrate permanent ties to it. If you don’t intend to make the U.S. a permanent residence, then this option may not be the correct choice. If you are found in non-compliance with this stipulation, then your status can get changed to “abandonment.”l hv

产品型号： 500x
产品报价：
产品特点： 500x持压泄压阀利用水力自动操作，即可以作泄压阀用又可作持压阀用
500x持压泄压阀的详细资料：
一、产品概述
500x持压泄压阀由主阀、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。
二、产品工作原理
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。
