正壓送風口

正壓(ya)送(song)風口當送(song)風體(ti)系(xi)中氣(qi)(qi)體(ti)溫度(du)到(dao)達防火閥(fa)機構上熔(rong)斷器(qi)動(dong)作，閥(fa)門(men)亦敏捷關(guan)閥(fa)切斷煙(yan)氣(qi)(qi)與(yu)火勢沿風管延伸的通(tong)路,樣(yang)在排(pai)煙(yan)體(ti)系(xi)中發生火災時排(pai)煙(yan)閥(fa)敞開進行排(pai)煙(yan)為了(le)截斷高溫煙(yan)氣(qi)(qi)在排(pai)煙(yan)管路中流(liu)動(dong)避免火勢延伸到(dao)另一防火分(fen)區當排(pai)出(chu)的煙(yan)氣(qi)(qi)溫度(du)到(dao)達調節效果在空調體(ti)系(xi)管路設計中。

正壓送風口質量雖然影響運用(yong)，可(ke)是后(hou)期(qi)的設備(bei)(bei)標準也相同(tong)(tong)重(zhong)要，為了到達我(wo)們預期(qi)的運用(yong)效果(guo)，我(wo)們除(chu)掉重(zhong)視材質與質量問題外，還要和施工(gong)單位溝通交流(liu)，確保后(hou)期(qi)的設備(bei)(bei)能滿(man)意市(shi)場(chang)的標準，同(tong)(tong)時滿(man)意不同(tong)(tong)建筑排煙通風的需求(qiu)，只需加工(gong)與設備(bei)(bei)于一(yi)體的質量保證，才能我(wo)們需要產品的目的。
