style="text-indent:25px">閥門的閥體和葉片基本大同小異，不同功能的閥門主要區(qū)別在于執(zhí)行機構(gòu)，所以要弄清楚防火閥的功能，就需要了解執(zhí)行機構(gòu)的基本原理。實現(xiàn)手動、溫控、電動動作的防火閥。溫感器遇高溫斷開，彈簧由拉伸狀態(tài)變?yōu)檎顟B(tài)，帶動杠桿和凸輪脫開，凸輪轉(zhuǎn)動帶動閥片轉(zhuǎn)動，實現(xiàn)溫度控制閥門動作；類似的，電磁鐵通電實現(xiàn)遠(yuǎn)程電動動作。常開和常閉是閥門出廠時的狀態(tài)，其差別只是閥門葉片和凸輪的安裝角度不同而已，比如0°時是常開，那么調(diào)成90°就是常閉。通風(fēng)管是火災(zāi)時不使用的到70度時關(guān)閉防火閥起到阻止火災(zāi)蔓延的作用。</p><div
