防(fang)火(huo)閥(fa)和排煙防(fang)火(huo)閥(fa)有(you)什么區別(bie)
出于安全的考慮,房屋一般都會安裝有防火閥,那它和排煙防火閥的區別有哪些?帶大家一起了解下吧。
1、結構(gou)不(bu)同
防火閥(fa)(fa)主(zhu)要由閥(fa)(fa)體(ti)和執(zhi)行機構(gou)(gou)組(zu)成(cheng)。閥(fa)(fa)體(ti)由殼(ke)體(ti)、法蘭、葉(xie)(xie)片及葉(xie)(xie)片聯動機構(gou)(gou)等組(zu)成(cheng)。執(zhi)行機構(gou)(gou)由外殼(ke)、葉(xie)(xie)片調(diao)節機構(gou)(gou)、離合器(qi)、溫度(du)熔(rong)斷器(qi)等組(zu)成(cheng)。
排(pai)煙(yan)防火閥作為消防部件一(yi)般(ban)安裝(zhuang)在(zai)機(ji)械排(pai)煙(yan)系統的管(guan)道上(shang),平(ping)時(shi)呈開(kai)啟狀(zhuang)態,火災時(shi)當排(pai)煙(yan)管(guan)道內煙(yan)氣溫度達到280度時(shi)關閉,并在(zai)一(yi)定(ding)時(shi)間內滿足(zu)漏煙(yan)量和耐(nai)火完整性要(yao)求,起隔煙(yan)阻火作用。主要(yao)材質:碳素鋼,鍍鋅板,不銹鋼。
2、工作原(yuan)理
防(fang)火閥的執行機構(gou)式通過金屬易熔片(pian)(pian)和離合(he)器(qi)機構(gou)來(lai)控制葉(xie)片(pian)(pian)的轉動(dong)。
排煙防火閥是(shi)平時常開,火災時也是(shi)開啟(qi)狀(zhuang)態,但當(dang)煙氣溫度達到280℃時,排煙防火閥自(zi)動(dong)關閉,聯動(dong)已(yi)經開啟(qi)的(de)風機停止運行。
防(fang)(fang)(fang)煙(yan)(yan)(yan)(yan)防(fang)(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)主(zhu)要(yao)(yao)應(ying)用于(yu)通風和空(kong)調(diao)(diao)系(xi)統(tong),防(fang)(fang)(fang)煙(yan)(yan)(yan)(yan)防(fang)(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)一般(ban)安(an)裝在通風系(xi)統(tong)和空(kong)調(diao)(diao)系(xi)統(tong)機(ji)房(fang)(fang)的防(fang)(fang)(fang)火(huo)(huo)分(fen)隔(ge)處(chu),是70攝氏度(du)(du)防(fang)(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa),平時(shi)(shi)常開(kai),當風管(guan)中(zhong)煙(yan)(yan)(yan)(yan)氣溫度(du)(du)達到(dao)70度(du)(du)是自(zi)動(dong)(dong)(dong)關(guan)閉。控(kong)制(zhi)(zhi)方式(shi)為(wei)自(zi)動(dong)(dong)(dong)。排(pai)煙(yan)(yan)(yan)(yan)防(fang)(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)主(zhu)侍雹昌要(yao)(yao)應(ying)用于(yu)機(ji)械排(pai)煙(yan)(yan)(yan)(yan)系(xi)統(tong)中(zhong),是280攝氏度(du)(du)肆吵防(fang)(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa),平時(shi)(shi)為(wei)常閉,火(huo)(huo)災發生時(shi)(shi)受火(huo)(huo)災自(zi)動(dong)(dong)(dong)報警聯動(dong)(dong)(dong)信號自(zi)動(dong)(dong)(dong)開(kai)啟,同時(shi)(shi)具備手(shou)動(dong)(dong)(dong)執行機(ji)構,可(ke)手(shou)動(dong)(dong)(dong)開(kai)啟,也可(ke)在消(xiao)防(fang)(fang)(fang)控(kong)制(zhi)(zhi)中(zhong)心遠程開(kai)啟(即聯動(dong)(dong)(dong)老扒控(kong)制(zhi)(zhi)、手(shou)動(dong)(dong)(dong)控(kong)制(zhi)(zhi)、自(zi)動(dong)(dong)(dong)控(kong)制(zhi)(zhi)三種方式(shi)),一般(ban)安(an)裝于(yu)排(pai)煙(yan)(yan)(yan)(yan)口(kou)、風管(guan)穿(chuan)越防(fang)(fang)(fang)火(huo)(huo)、防(fang)(fang)(fang)煙(yan)(yan)(yan)(yan)分(fen)區分(fen)隔(ge)處(chu)和排(pai)煙(yan)(yan)(yan)(yan)機(ji)房(fang)(fang)風管(guan)穿(chuan)墻處(chu),當風管(guan)中(zhong)煙(yan)(yan)(yan)(yan)氣溫度(du)(du)達到(dao)280度(du)(du)時(shi)(shi)關(guan)閉。
在通(tong)風系統(tong)和排煙系統(tong)中使用的(de)只(zhi)有(you)防煙防火閥和排煙防火閥這兩種閥組(zu)。
