上海(hai)閥(fa)(fa)盛閥(fa)(fa)門制造有限(xian)公司(si)主要生產多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)，可提供多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)價格，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)說明書，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)實物圖，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)結構(gou)圖，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)外形尺寸(cun)，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)執行標準，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)工作原理(li)，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥(fa)(fa)作用(yong)特(te)點。

GFD/Q多功(gong)能阻火呼(hu)吸閥(fa)類似于單向止逆閥(fa),它只能向外呼(hu)氣,不能向內吸氣,當系統內壓(ya)力升高時,氣體便經過向外放空,保證系統的壓(ya)力恒定。一般它被用在常壓(ya)或低壓(ya)貯罐上。

焦炭塔(ta)的呼吸閥有兩個(ge)用處：放水(shui)(shui)時(shi)吸氣以(yi)利塔(ta)內存(cun)水(shui)(shui)順(shun)利放出(chu),呼氣蒸(zheng)汽(qi)趕(gan)空(kong)氣時(shi),用以(yi)放凈空(kong)氣,脫水(shui)(shui)放汽(qi)時(shi),用以(yi)檢(jian)查塔(ta)內是否為(wei)正壓。

GFD/Q多功(gong)能呼吸閥(fa)閥(fa)體的材(cai)質有:鑄(zhu)鐵、鑄(zhu)鋼、不銹鋼、鋁合金(jin)。工(gong)作壓力(li)0.6-6.4MPA，工(gong)作溫度(du)-20°C-425C°。閥(fa)門口(kou)徑從 DN15-DN300。連接方式:法蘭、對夾、絲(si)口(kou)或焊接。

驅動(dong)(dong)方式:手動(dong)(dong)、蝸輪、氣(qi)動(dong)(dong)、電動(dong)(dong)。

多功能呼吸閥適用(yong)介(jie)質:水(shui)、油品、氣、蒸汽(qi)。主要領域：化工(gong)設(she)(she)備(bei)、通(tong)用(yong)零部(bu)件、工(gong)業設(she)(she)備(bei)、制藥設(she)(she)備(bei)、通(tong)用(yong)設(she)(she)備(bei)、石化設(she)(she)備(bei)。
