丹富斯500X泄压阀产品概述:
500X泄压/持压阀由主阀、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。 丹富斯泄压/持压阀,泄压阀性能,泄压阀作用
本产品利用水力自动控制,不需要其它装置和能源,保养简便,一阀多用。
本产品广泛应用于高层建筑、生活区等供水管网系统及城市供水工程。

丹富斯500X泄压阀工作原理:
1、作泄压阀:当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,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。

Dan fuss, 500 x relief valve products overview:
500 x pressure relief/holding pressure valve consists of the main valve, pilot valve, needle valve, ball valve, micro shape filter and pressure gauge of hydraulic control of system. Use of hydraulic automatic operation, can make the pressure release valve and can be used for holding pressure valve. As a pressure relief valve, it can maintain water supply way pressure under the TVC of set; For holding pressure valve, can maintain the main valve upstream water pressure above the set value, maintain the main valve upstream water supply pressure.
This product use hydraulic automatic control, do not need other devices and energy, maintenance is simple, one valve is multi-purpose.
This product is widely used in high-rise buildings, living quarters and other water supply pipe network system and urban water supply engineering.
Dan fuss, 500 x relief valve working principle:
1, A pressure relief valve: when the pilot valve is adjusted for the pressure state, water through the needle valve, the main valve control room, ball valve, A pressure relief/holding pressure pilot valve, ball valve B of exports, at this time the main valve is fully open. When the inlet pressure exceeds the TVC of pilot valve set, pressure pilot valve will automatically open, channelled through ball valve C section water, make the line pressure. When the pressure recovery to TVC, pressure relief valve automatically shut down. As a pressure relief valve, ball valve normally open.
2, for holding pressure valve: when the pilot valve is adjusted for holding pressure, as long as the main valve import water pressure is lower than the pilot valve set point, pilot valve is closed. The main control room booster, the main valve closed. When the main valve upstream water supply pressure exceeds pilot valve set pressure, pilot valve to open, the control room of water through the ball valve to the export, the control room main reducing valve open, began to water supply, that maintain the upstream water pressure. For holding pressure valve, ball valve normally closed C or substituted a plug.
