一般正壓送風口內部都安裝了正壓送(song)風(feng)(feng)口(kou)，該正壓送(song)風(feng)(feng)口(kou)有什么作(zuo)用(yong)呢(ni)?下(xia)邊簡易(yi)來剖析(xi)一下(xia)：假如發生(sheng)了火(huo)情的(de)狀(zhuang)況，正壓送(song)風(feng)(feng)口(kou)排放煙(yan)霧(wu)離心(xin)(xin)風(feng)(feng)機(ji)(ji)里(li)邊就會獨立打開(kai)正壓力(li)離心(xin)(xin)風(feng)(feng)機(ji)(ji)或是(shi)人力(li)火(huo)情自然災害報警電機(ji)(ji)板(ban)會獨立打開(kai)，正壓送(song)風(feng)(feng)口(kou)打開(kai)房屋頂(ding)端的(de)正數(shu)氣體(ti)壓強的(de)離心(xin)(xin)風(feng)(feng)機(ji)(ji)及(ji)塔出口(kou)，抽走里(li)邊的(de)氣體(ti)，出口(kou)樓梯口(kou)前側屋子的(de)工(gong)作(zuo)壓力(li)。
