高溫安全閥

  2.4先導式(脈沖式)。利用導閥與主閥連在一起,通過導閥的脈沖作用驅動主閥動作。適用于大口徑、大排量及高壓系統。先導式安全閥與導閥采用無縫管接通,由先導閥來感測被控壓力信號并控制主閥的啟閉。其動作過程是: 當安全閥的閥前壓力低于整定壓力時,先導閥整定彈簧將閥芯推向閥座密封面,氣體介質經導閥進口進入主閥閥芯上腔,使閥芯下移貼緊閥座,導閥和主閥都處于無泄漏的關閉狀態;當閥前壓力達到或高于整定壓力時,介質壓力克服整定壓力,彈簧將導閥閥芯推向上移,導閥受力面積由閥芯面積轉化為活塞受力面積,受力面積增加上升力增大,導閥開啟。主閥閥套上腔內的氣體從導閥出口排出,主閥打開,介質迅速排放,活塞行程到大位置。當介質壓力排放到一定壓力時,通過活塞阻尼孔的介質壓力使活塞上下兩端產生面積壓差平衡,啟閉壓差由活塞上下兩端面積壓差平衡實現,當閥前壓力降回到工作壓力以下時,在較小彈簧力作用下,閥芯下移實現其密封。導閥關閉,主閥也就隨之而關閉。
