英国Bifold泄压阀原厂技术支持
CPR自备通风压力释放阀可直接作用，可从外部调节，适用于低压应用。额定压力高达8 bar，设定点压力根据用户规格在出厂时设定。 设定点可现场调节。阀座采用硅胶面密封，具有出色的再密封特性
泄压阀根据系统的工作压力能自动启闭，一般安装于封闭系统的设备或管路上保护系统安全，当设备或管道内压力X过泄压阀设定压力时，即自动开启泄压，保证设备和管道内介质压力在设定压力之下，保护设备和管道，防止发生意外。
工作原理
泄压阀是由针形阀I、压力表2、主阀3、导阀4及连接管等部件组成。
它是水力控制阀的一种。主阀被隔膜分成上、下两部分，隔膜下腔为水流通道，上腔为控制室，由它来控制主阀阀瓣的启闭。导阀本身就是一个泄压阀，它也有控制室和水流通道，阀瓣启闭由控制室控制。针形阀即节流阀，它控制着连接管中水的流量。
在消防给水系统运行过程中，主管道水流方向自左向右，一路控制水进入导阀控制室，当水的压力小于设定泄压值时，导阀弹簧的推力大于水的压力，导阀阀瓣处于关闭状态。另一路控制水经节流针形阀进入主阀上腔后产生一个静压，上腔的压强和生流道内的压强相等。由于主阀阀瓣上平面大于下平面，所以上腔对阍瓣的压力大于主流道内水对问瓣的推方，使主阀处于关闭状态。如果主管道水流压力升高并X过设定的泄压值，经控制管进入导管控制室的水流压力增加，水的压力大于弹簧推力 此时导阀被打开，主阀上淀开始泄压。由于受节流阀节制，补水不足，造成主阀上腔压力减小，主阀同瓣下髓冰。流推力大于上腔压力，阀瓣上升，主阀打开迅速泄压。由于上述过程是在瞬间完成的，所以室内消防给水系统在发生X压时，不会造成危害。
