上(shang)海閥(fa)(fa)(fa)盛閥(fa)(fa)(fa)門制(zhi)造有限公司主要生產多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)，可提(ti)供多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)價格，多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)說明(ming)書，多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)實(shi)物圖，多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)結構圖，多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)外形(xing)尺寸，多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)執行(xing)標準，多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)工作原理(li)，多功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)作用特點。

GFD/Q多功能阻火呼吸閥(fa)類似于單向(xiang)(xiang)止(zhi)逆閥(fa),它只(zhi)能向(xiang)(xiang)外呼氣,不能向(xiang)(xiang)內吸氣,當系(xi)統內壓(ya)(ya)力(li)升高時,氣體(ti)便經過向(xiang)(xiang)外放空,保證系(xi)統的(de)壓(ya)(ya)力(li)恒定。一般它被用在常壓(ya)(ya)或低壓(ya)(ya)貯罐上。

焦炭塔的呼吸閥有(you)兩(liang)個(ge)用處：放(fang)(fang)水(shui)時(shi)吸氣(qi)(qi)以利塔內存(cun)水(shui)順(shun)利放(fang)(fang)出,呼氣(qi)(qi)蒸汽(qi)趕(gan)空氣(qi)(qi)時(shi),用以放(fang)(fang)凈空氣(qi)(qi),脫水(shui)放(fang)(fang)汽(qi)時(shi),用以檢查塔內是否為正壓。

GFD/Q多功(gong)能呼吸(xi)閥閥體的材質有(you):鑄鐵、鑄鋼、不銹鋼、鋁合(he)金(jin)。工作(zuo)壓(ya)力(li)0.6-6.4MPA，工作(zuo)溫度(du)-20°C-425C°。閥門口徑從 DN15-DN300。連(lian)接方式:法蘭、對夾、絲(si)口或焊接。

驅動(dong)(dong)(dong)方式:手動(dong)(dong)(dong)、蝸輪、氣動(dong)(dong)(dong)、電(dian)動(dong)(dong)(dong)。

多功能呼吸閥適用(yong)介(jie)質:水、油品、氣(qi)、蒸(zheng)汽(qi)。主要領域：化工設(she)(she)備(bei)、通(tong)用(yong)零部件、工業(ye)設(she)(she)備(bei)、制(zhi)藥設(she)(she)備(bei)、通(tong)用(yong)設(she)(she)備(bei)、石化設(she)(she)備(bei)。
