主要特点：​

1、螺线管外壳可自由旋转360º，便于电缆布局，便于连接布线
    电磁铁内部构件随外壳一起旋转，防止电缆从接线端子中拉出。

2、最广泛的覆盖选项（自动复位，弹簧复位手动覆盖，保持输出手动覆盖，手动复位，防篡改手动闩锁，闩锁通电）。

3、电磁阀可以任何方向安装，以简化安装。

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超过设定的泄压值，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超压时，不会造成危害。 

 

分类

 

泄压阀结构主要有两大类：弹簧式和杠杆式。 

弹簧式是指阀瓣与阀座的密封靠弹簧的作用力。

杠杆式是靠杠杆和重锤的作用力。 

随着大容量的需要，又有一种脉冲式泄压阀，也称为先导式泄压阀，由主泄压阀和辅助阀组成。当管道内介质压力超过规定压力值时，辅助阀先开启，介质沿着导管进入主泄压阀，并将主泄压阀打开，使增高的介质压力降低。

 

如果主管道水流压力继续增加，导阀开启量也随之加大 使得主阀上腔与下腔的压差更大，主阀开启量也越大，系统泄压更快。反之，如果主管道水流压力减小(如室内消火栓使用个数增加或开启喷头个数增多时)，导阀控制室压力随之减小，导阀开启量变小。主阀上腔压力增大，主阀阀瓣询下关小，使主管道水流压力稳定在系统设计。

 

特点

1、准确且保持不变的安全稳定压力，一旦超压，泄压阀能充分打开及时泄压。 

2、关闭速度可调，消除压力波动。 

3、隔膜传动机构将操作滞后现象减小到最小。

4、它可安装在任何位置，不用改变压力设定值或从管路上拆除就可进行维修和检查。
