遠控(kong)(kong)排煙防火(huo)調(diao)節閥(fa)，采用遠控(kong)(kong)執行機構，一般為6米鋼絲(si)繩遠距離控(kong)(kong)制，鍍鋅板閥(fa)體。安裝在通風、空(kong)調(diao)調(diao)節系統的送、回風管道上，起隔煙阻火(huo)作用的閥(fa)門。

越(yue)舜正(zheng)壓(ya)送風閥（口(kou)(kou)）是(shi)用于發生火災時加(jia)壓(ya)送風，通(tong)過正(zheng)壓(ya)送風口(kou)(kou)會(hui)*的(de)對前室進行送風，使(shi)前室維持正(zheng)壓(ya)，保證煙(yan)氣不會(hui)在這個區域蔓延，而給人逃生的(de)空間的(de)。

電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)調(diao)節閥的電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)執行器(qi)有方、圓(yuan)兩種形式。方形電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)執行器(qi)，可以(yi)手(shou)動(dong)(dong)(dong)(dong)脫開電(dian)(dian)(dian)機齒輪，進行手(shou)動(dong)(dong)(dong)(dong)調(diao)節；而圓(yuan)形電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)執行器(qi)不可以(yi)。圓(yuan)形電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)執行器(qi)運(yun)轉較(jiao)平穩(wen)可輸出反饋電(dian)(dian)(dian)信號與自動(dong)(dong)(dong)(dong)控制系統聯鎖。

手(shou)動(dong)(dong)對開多(duo)葉式調(diao)(diao)節(jie)閥適用(yong)(yong) : 對開多(duo)葉風(feng)(feng)量調(diao)(diao)節(jie)閥，一般用(yong)(yong)在空調(diao)(diao) \ 通(tong)風(feng)(feng)系(xi)統管道中，用(yong)(yong)來調(diao)(diao)節(jie)支管的(de)風(feng)(feng)量，也(ye)可用(yong)(yong)于新風(feng)(feng)與回風(feng)(feng)的(de)混合調(diao)(diao)節(jie)。該(gai)閥分(fen)(fen)為手(shou)動(dong)(dong)和電(dian)(dian)動(dong)(dong)兩種(zhong)(zhong)，按密封性(xing)來分(fen)(fen)，還(huan)可分(fen)(fen)成密閉型和普通(tong)型兩種(zhong)(zhong)。電(dian)(dian)動(dong)(dong)可以自動(dong)(dong)控制調(diao)(diao)節(jie)風(feng)(feng)量與自控系(xi)統配套。
