GFD/Q多功能(neng)阻火呼吸閥(fa)類(lei)似于單(dan)向(xiang)止(zhi)逆閥(fa),它只(zhi)能(neng)向(xiang)外(wai)呼氣,不(bu)能(neng)向(xiang)內(nei)吸氣,當系統內(nei)壓(ya)力(li)升高時,氣體便經過向(xiang)外(wai)放(fang)空,保證系統的壓(ya)力(li)恒定(ding)。一(yi)般它被用在(zai)常壓(ya)或低壓(ya)貯罐(guan)上。

焦炭塔的呼吸閥有兩(liang)個用處：放(fang)水(shui)時(shi)吸氣(qi)以利塔內存水(shui)順利放(fang)出,呼氣(qi)蒸汽(qi)(qi)趕(gan)空氣(qi)時(shi),用以放(fang)凈空氣(qi),脫水(shui)放(fang)汽(qi)(qi)時(shi),用以檢查塔內是否為正(zheng)壓(ya)。
