九龍坡值得信賴的風機通風管批發

在空(kong)調送(song)風(feng)(feng)系(xi)統(tong)中(zhong)，空(kong)調送(song)風(feng)(feng)機(ji)送(song)出(chu)的風(feng)(feng)必(bi)須通(tong)過(guo)主(zhu)干(gan)管分配(pei)到支管中(zhong)；在排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)系(xi)統(tong)中(zhong)，煙(yan)(yan)(yan)氣(qi)(qi)由(you)支管到主(zhu)干(gan)管后，進入(ru)排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)風(feng)(feng)機(ji)排(pai)(pai)(pai)(pai)出(chu)。當(dang)建筑物內發(fa)生火(huo)災時，在通(tong)風(feng)(feng)、空(kong)調系(xi)統(tong)中(zhong)，為了(le)防(fang)止火(huo)勢(shi)通(tong)過(guo)送(song)風(feng)(feng)系(xi)統(tong)蔓延(yan)，當(dang)送(song)風(feng)(feng)系(xi)統(tong)中(zhong)氣(qi)(qi)體溫度達到70℃時，防(fang)火(huo)閥(fa)(fa)機(ji)構上熔(rong)斷器(qi)動作，閥(fa)(fa)門(men)亦迅速關(guan)閥(fa)(fa)，切斷煙(yan)(yan)(yan)氣(qi)(qi)與火(huo)勢(shi)沿風(feng)(feng)管蔓延(yan)的通(tong)路。同樣，在排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)系(xi)統(tong)中(zhong)，發(fa)生火(huo)災時，排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)閥(fa)(fa)開啟，進行(xing)排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)，為了(le)截斷高溫煙(yan)(yan)(yan)氣(qi)(qi)在排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)管路中(zhong)流動，防(fang)止火(huo)勢(shi)蔓延(yan)到另一防(fang)火(huo)分區，當(dang)排(pai)(pai)(pai)(pai)出(chu)的煙(yan)(yan)(yan)氣(qi)(qi)溫度達到280℃時，排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)防(fang)火(huo)閥(fa)(fa)、排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)口上熔(rong)斷器(qi)動作，閥(fa)(fa)門(men)必(bi)須自動關(guan)閉，阻止排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)。由(you)此可見，防(fang)火(huo)閥(fa)(fa)、排(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)閥(fa)(fa)做到了(le)該(gai)通(tong)則通(tong)，該(gai)斷則斷的隔煙(yan)(yan)(yan)阻火(huo)作用。
