防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)、排(pai)(pai)(pai)(pai)煙(yan)(yan)閥(fa)(fa)(fa)是通(tong)(tong)風(feng)、空(kong)(kong)調(diao)、排(pai)(pai)(pai)(pai)煙(yan)(yan)系統(tong)的(de)(de)重(zhong)要組(zu)成部分。通(tong)(tong)風(feng)空(kong)(kong)調(diao)、排(pai)(pai)(pai)(pai)煙(yan)(yan)系統(tong)中所有離心(xin)風(feng)機(ji)和消防(fang)(fang)專用排(pai)(pai)(pai)(pai)煙(yan)(yan)軸流風(feng)機(ji)安裝(zhuang)調(diao)試時(shi),為(wei)安全起見,電(dian)機(ji)啟動(dong)電(dian)流Z小,一(yi)般為(wei)空(kong)(kong)載啟動(dong),通(tong)(tong)過閥(fa)(fa)(fa)門臨(lin)時(shi)切斷管(guan)道(dao)實現。同樣,在(zai)(zai)排(pai)(pai)(pai)(pai)煙(yan)(yan)系統(tong)中,發(fa)生(sheng)火(huo)(huo)災時(shi),打開排(pai)(pai)(pai)(pai)煙(yan)(yan)閥(fa)(fa)(fa)進行排(pai)(pai)(pai)(pai)煙(yan)(yan)。為(wei)了切斷高溫煙(yan)(yan)氣在(zai)(zai)排(pai)(pai)(pai)(pai)煙(yan)(yan)管(guan)道(dao)中的(de)(de)活動(dong),防(fang)(fang)止火(huo)(huo)勢(shi)蔓延到另一(yi)個防(fang)(fang)火(huo)(huo)分區,當排(pai)(pai)(pai)(pai)煙(yan)(yan)溫度達到280℃時(shi),排(pai)(pai)(pai)(pai)煙(yan)(yan)防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)和排(pai)(pai)(pai)(pai)煙(yan)(yan)口(kou)(kou)上的(de)(de)保(bao)險絲必須自(zi)動(dong)關閉(bi),以防(fang)(fang)止排(pai)(pai)(pai)(pai)煙(yan)(yan)。通(tong)(tong)風(feng)設備工程(cheng)中,防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)包(bao)括(kuo)重(zhong)力防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)、防(fang)(fang)火(huo)(huo)調(diao)節(jie)閥(fa)(fa)(fa)、防(fang)(fang)火(huo)(huo)風(feng)口(kou)(kou)、氣動(dong)防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)、防(fang)(fang)煙(yan)(yan)防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)、電(dian)子自(zi)控防(fang)(fang)煙(yan)(yan)防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)等(deng)產(chan)品;排(pai)(pai)(pai)(pai)煙(yan)(yan)閥(fa)(fa)(fa)包(bao)括(kuo)排(pai)(pai)(pai)(pai)煙(yan)(yan)防(fang)(fang)火(huo)(huo)閥(fa)(fa)(fa)、板式排(pai)(pai)(pai)(pai)煙(yan)(yan)口(kou)(kou)(天花板)、豎井排(pai)(pai)(pai)(pai)煙(yan)(yan)口(kou)(kou)等(deng)產(chan)品。建筑(zhu)物(wu)發(fa)生(sheng)火(huo)(huo)災時(shi),在(zai)(zai)通(tong)(tong)風(feng)、空(kong)(kong)調(diao)系統(tong)中。
為防(fang)止火(huo)(huo)(huo)災(zai)(zai)通(tong)(tong)過送(song)(song)風(feng)系(xi)(xi)(xi)統(tong)蔓延(yan),當通(tong)(tong)風(feng)管(guan)道(dao)內氣(qi)體(ti)溫度達(da)到(dao)(dao)70℃時,保(bao)險絲在防(fang)火(huo)(huo)(huo)閥(fa)機構上(shang)移(yi)動,閥(fa)門(men)也迅速關閉(bi)閥(fa)門(men),堵塞煙氣(qi)和火(huo)(huo)(huo)災(zai)(zai)沿風(feng)管(guan)蔓延(yan)的通(tong)(tong)道(dao)。在通(tong)(tong)風(feng)、空調系(xi)(xi)(xi)統(tong)管(guan)道(dao)設計中(zhong)(zhong),雖然計算,但如果(guo)實(shi)際工程運行條件發生變化,需要(yao)通(tong)(tong)過防(fang)火(huo)(huo)(huo)閥(fa)調節系(xi)(xi)(xi)統(tong)各部門(men)的風(feng)量,進行系(xi)(xi)(xi)統(tong)調試,固定閥(fa)門(men)開度,公平分配,以滿足設計要(yao)求(qiu)。在送(song)(song)風(feng)系(xi)(xi)(xi)統(tong)中(zhong)(zhong),送(song)(song)風(feng)機送(song)(song)出的風(feng)必須通(tong)(tong)過主管(guan)分配到(dao)(dao)支(zhi)(zhi)管(guan)中(zhong)(zhong);在排煙系(xi)(xi)(xi)統(tong)中(zhong)(zhong),煙氣(qi)從支(zhi)(zhi)管(guan)到(dao)(dao)主管(guan)后,進入排煙風(feng)機排出。由(you)此(ci)可見(jian),防(fang)火(huo)(huo)(huo)閥(fa)、排煙閥(fa)達(da)到(dao)(dao)了通(tong)(tong)則通(tong)(tong)、斷則斷的防(fang)火(huo)(huo)(huo)效果(guo)。
