G200X沟槽先导式减压阀是水力控制阀门中的减压阀,是一种利用介质自身能量来调节与控制管路压力的职能型阀门。此阀门针对高层建筑设计,通过调节减压导阀,即可调节主阀的出口压力。出口压力不因进口压力、进口流量的变化而变化,安全可靠地将出口压力维持在设定值上,并可根据需要调节设定值以达到减压目的。该阀减压, 性能稳定、安全可靠、安装方便,使用寿命长,主要用于解决高层建筑生活用水、消防用水系统中,要求流量大、灵敏度高等场合,取代中间水箱,节约建筑中间水箱的费用,扩大建筑物的使用面积。被广泛适用于高层建筑、工业给水、消防供水及生活用水管网系统及城市供水工程领域。

Working Principle

当阀门从进口端给水时,水流过针阀进入主阀控制室,出口压力通过导管作用到导阀上。当出口压力高于导阀弹簧设定值时,导阀关闭。控制室停止排水,此时主阀控制室内压力升高并关闭主阀,出口压力不再升高。当阀门出口压力降到导阀弹簧设定压力时,导阀开启,控制室向下游排水。由于导阀系统排水量大于针阀的进水量,主阀控制室压力下降。进口压力使主阀开启。在稳定状态下,控制室进水、排水相同,主阀开度不变,出口压力稳定。

Product Features

G200X沟槽先导式减压阀由主阀、导阀、针阀、球阀、微型过滤器和压力表组成水力控制接管系统。使用时,当调定出口压力后,能自动保持稳定出口压力。本产品利用导阀自力控制,不需要其它装置和能源,保养简便,压力控制准确度高,受进口压力和流量影响小,减压稳压可靠。
