上海(hai)閥盛(sheng)閥門(men)制造有限(xian)公(gong)司(si)主要生(sheng)產HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥，可(ke)提(ti)供HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥價格，HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥說明書，HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥實物(wu)圖，HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥結構圖，HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥外形尺寸(cun)，HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥執(zhi)行標(biao)準，HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥工作(zuo)原理，HXF-4接(jie)(jie)管(guan)(guan)(guan)(guan)式(shi)(shi)呼(hu)(hu)吸(xi)閥作(zuo)用特點。

HXF-4接(jie)管式呼吸閥類(lei)似(si)于(yu)單向(xiang)止逆閥,它只能(neng)向(xiang)外呼氣(qi),不能(neng)向(xiang)內(nei)吸氣(qi),當系統內(nei)壓(ya)力(li)升高時(shi)(shi),氣(qi)體便(bian)經過向(xiang)外放(fang)(fang)空(kong),保證系統的壓(ya)力(li)恒定。一般它被(bei)用(yong)在(zai)常壓(ya)或(huo)低(di)壓(ya)貯罐上。焦炭塔的呼吸閥有兩個(ge)用(yong)處：放(fang)(fang)水時(shi)(shi)吸氣(qi)以(yi)利塔內(nei)存水順(shun)利放(fang)(fang)出,呼氣(qi)蒸汽(qi)趕空(kong)氣(qi)時(shi)(shi),用(yong)以(yi)放(fang)(fang)凈空(kong)氣(qi),脫水放(fang)(fang)汽(qi)時(shi)(shi),用(yong)以(yi)檢(jian)查塔內(nei)是否為正壓(ya)。
