style="text-indent:25px">至于排煙類閥門的自動復(fù)位功能，規(guī)范和消防認證要求只要具備復(fù)位功能即可，通常情況只要具備手動復(fù)位功能就可以滿足要求。因為排煙系統(tǒng)使用的概率非常小，就算使用也是其中少數(shù)幾個系統(tǒng)會啟動，為了不確定的其中幾個閥門就讓所有閥門都具備電動復(fù)位功能，顯然是沒有必要的，火災(zāi)完根據(jù)動作信號手動復(fù)位即可，并沒有多大的工作量。當然如果預(yù)算足夠，規(guī)定所有的閥門均具備自動復(fù)位功能也未嘗不可，應(yīng)注意有遠距離復(fù)位功能的閥門，當通電動作后，應(yīng)具有顯示閥門葉片位置的信號輸出防火閥，一般安裝在風(fēng)管穿越防火墻和結(jié)構(gòu)變形縫處，起火災(zāi)控制作用。汕頭防火閥廠商哪家好</p><p

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。三沙防火閥一般多少錢</p><p
