主要特點：?

1、螺線管外殼可自由旋轉360º，便于電纜布局，便于連接布線
    電磁鐵內部構件隨外殼一起旋轉，防止電纜從接線端子中拉出。

2、最廣泛的覆蓋選項（自動復位，彈簧復位手動覆蓋，保持輸出手動覆蓋，手動復位，防篡改手動閂鎖，閂鎖通電）。

3、電磁閥可以任何方向安裝，以簡化安裝。

工作原理

泄壓閥是由針形閥I、壓力表2、主閥3、導閥4及連接管等部件組成。 

它是水力控制閥的一種。主閥被隔膜分成上、下兩部分，隔膜下腔為水流通道，上腔為控制室，由它來控制主閥閥瓣的啟閉。導閥本身就是一個泄壓閥，它也有控制室和水流通道，閥瓣啟閉由控制室控制。針形閥即節(jié)流閥，它控制著連接管中水的流量。 

在消防給水系統(tǒng)運行過程中，主管道水流方向自左向右，一路控制水進入導閥控制室，當水的壓力小于設定泄壓值時，導閥彈簧的推力大于水的壓力，導閥閥瓣處于關閉狀態(tài)。另一路控制水經節(jié)流針形閥進入主閥上腔后產生一個靜壓，上腔的壓強和生流道內的壓強相等。由于主閥閥瓣上平面大于下平面，所以上腔對閽瓣的壓力大于主流道內水對問瓣的推方，使主閥處于關閉狀態(tài)。如果主管道水流壓力升高并超過設定的泄壓值，經控制管進入導管控制室的水流壓力增加，水的壓力大于彈簧推力 此時導閥被打開，主閥上淀開始泄壓。由于受節(jié)流閥節(jié)制，補水不足，造成主閥上腔壓力減小，主閥同瓣下髓冰。流推力大于上腔壓力，閥瓣上升，主閥打開迅速泄壓。由于上述過程是在瞬間完成的，所以室內消防給水系統(tǒng)在發(fā)生超壓時，不會造成危害。 

 

分類

 

泄壓閥結構主要有兩大類：彈簧式和杠桿式。 

彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。

杠桿式是靠杠桿和重錘的作用力。 

隨著大容量的需要，又有一種脈沖式泄壓閥，也稱為先導式泄壓閥，由主泄壓閥和輔助閥組成。當管道內介質壓力超過規(guī)定壓力值時，輔助閥先開啟，介質沿著導管進入主泄壓閥，并將主泄壓閥打開，使增高的介質壓力降低。

 

如果主管道水流壓力繼續(xù)增加，導閥開啟量也隨之加大 使得主閥上腔與下腔的壓差更大，主閥開啟量也越大，系統(tǒng)泄壓更快。反之，如果主管道水流壓力減小(如室內消火栓使用個數(shù)增加或開啟噴頭個數(shù)增多時)，導閥控制室壓力隨之減小，導閥開啟量變小。主閥上腔壓力增大，主閥閥瓣詢下關小，使主管道水流壓力穩(wěn)定在系統(tǒng)設計。

 

特點

1、準確且保持不變的安全穩(wěn)定壓力，一旦超壓，泄壓閥能充分打開及時泄壓。 

2、關閉速度可調，消除壓力波動。 

3、隔膜傳動機構將操作滯后現(xiàn)象減小到最小。

4、它可安裝在任何位置，不用改變壓力設定值或從管路上拆除就可進行維修和檢查。
