上海閥(fa)盛閥(fa)門制造有(you)限(xian)公司主要(yao)生產HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)，可提(ti)供HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)價格，HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)說明(ming)書，HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)實(shi)物圖，HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)結構圖，HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)外(wai)形尺(chi)寸，HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)執(zhi)行標準，HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)工(gong)作原理，HXF-4接(jie)(jie)管(guan)式(shi)(shi)呼(hu)吸(xi)(xi)(xi)閥(fa)作用特點。

HXF-4接管式呼吸(xi)閥(fa)類似于單向止逆閥(fa),它只能向外呼氣(qi),不能向內吸(xi)氣(qi),當系(xi)統內壓(ya)(ya)力(li)升高時(shi)(shi),氣(qi)體(ti)便經(jing)過(guo)向外放(fang)空(kong),保證系(xi)統的壓(ya)(ya)力(li)恒定。一般它被用(yong)(yong)在常(chang)壓(ya)(ya)或低壓(ya)(ya)貯(zhu)罐上。焦炭(tan)塔(ta)的呼吸(xi)閥(fa)有兩個(ge)用(yong)(yong)處：放(fang)水(shui)時(shi)(shi)吸(xi)氣(qi)以(yi)(yi)利塔(ta)內存水(shui)順利放(fang)出(chu),呼氣(qi)蒸汽趕空(kong)氣(qi)時(shi)(shi),用(yong)(yong)以(yi)(yi)放(fang)凈空(kong)氣(qi),脫(tuo)水(shui)放(fang)汽時(shi)(shi),用(yong)(yong)以(yi)(yi)檢(jian)查塔(ta)內是否為正壓(ya)(ya)。
