Product Description

一、工作原理


500X持压泄压阀一般安装在泄水旁路上,与主管道并联安装。上游压力低于导阀设定值,导阀关闭;上游压力作用在主阀膜室腔内,使主阀维持关闭。一但上游压力逐渐上升到超过导阀设定值,导阀就会开启,泄放主阀系统侧的压力水;此时主阀开启,大量泄水降压至设定值时,才缓慢平稳关闭,不产生二次水锤。适用于消除因流量供大于需而逐渐增大过高压力,当管道压力值低于阀门设定值后自动关闭;持压泄压阀的动作压力连续可调。


二、产品介绍


持压泄压阀由主阀、导阀、针阀、过滤器、压力表及连接管路组成。主阀为隔膜式结构。通过调节导阀的设定值及针阀开度,可以方便的设定阀门的动作压力;并通过接管系统和膜室腔来稳定出口压力。我公司生产的 持压减压阀技术成熟,做工精细,制造精良,且具有工作性能稳定,动作灵敏,维护方便,使用可靠等优点。被用于各类应用水灭火的场所,且有多种规格可供选择。 500X-16/25Q 持压泄压阀


三、产品用途


500X持压泄压阀广泛用于消防、给排水、石化、电厂等行业中。保护系统管网的稳定工作,防止水压过高造成系统故障。
