AX742X隔膜式安全泄压阀安装在建筑、给水系统以及其它给水系统的管道上,当给水管路中压力超过泄压阀设定压力时,AX742X隔膜式安全泄压阀自动开启泄压,也可作持压阀用,符合主阀上游的供水压力。当管道从进水端给水时,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;当出口压力降到导阀设定压力时导阀开启,控制室向下游排水,由于导阀的排水量大于针阀的进水量,主阀控制室压力下降,入口压力使主阀开启;稳定状态下,控制室进水、排水相同,开度不变,出口压力不变。调节导阀弹簧可设定出口压力。

工作特点

  • 压力控制稳定。导阀、主阀连续工作,下游压力变化连续、平稳,受入口压力影响小。
  • 操作方便。工作压力调定后,当上游压力或流量变动时主阀自动调节,稳定了下游压力。
  • 阀体采用了全通道、直流式、流线型设计。水力损失小,节能效果好。

Scope of Application

Urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other fields.
