渝北值得信賴的消防通風設備批發

（1）防火閥使用及安裝（a） 安裝前必須檢查防火閥外觀質量、控制性能和閥門動作，確認正常后配鉆法蘭連接孔。（b） 安裝時防火閥的方向位置應正確，熔斷器（易熔片）應先于葉片軸接觸熱氣流（即位于葉片的迎風側）。自重式防火閥要注意葉片的上下方向氣流方向標志，不得倒置。（c） 防火閥應牢靠地固定在設定的位置上，確保當發生火災時不致因管道變形下塌而影響工作性能，消防通風設備批發必要時應設吊架。（d） 具有風量調節功能的防火閥，應在調試過程中調定閥門開度。（e） 當設計防火閥為吊頂安裝或靠近墻體安裝時，要保證防火閥周圍貿有足夠空間。（f） 安裝防火閥后的施工過程中，要注意值得信賴的消防通風設備不(bu)得(de)使閥(fa)體、操(cao)作裝(zhuang)置等受(shou)到損傷、變形(xing)，以免影響其工作性能（g） 安裝(zhuang)后應(ying)對防(fang)火閥(fa)清掃檢查，閥(fa)體內不(bu)得(de)有雜(za)物，并(bing)進行(xing)操(cao)作試驗，確(que)保閥(fa)體正常工作。
