上海閥(fa)(fa)(fa)盛閥(fa)(fa)(fa)門制造有(you)限公司主要生產多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)，可(ke)提供多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)價格(ge)，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)說明書，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)實物圖，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)結構圖，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)外形尺(chi)寸，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)執行標準，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)工作原理，多(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)作用(yong)特點。

GFD/Q多功(gong)能(neng)阻火呼(hu)吸閥(fa)類似于單向(xiang)(xiang)止逆(ni)閥(fa),它只能(neng)向(xiang)(xiang)外呼(hu)氣,不能(neng)向(xiang)(xiang)內吸氣,當系(xi)統內壓力(li)(li)升高時,氣體便經過向(xiang)(xiang)外放空,保證系(xi)統的(de)壓力(li)(li)恒定(ding)。一般它被用(yong)在(zai)常壓或低壓貯(zhu)罐(guan)上。

焦炭(tan)塔的呼吸閥有兩個用(yong)處(chu)：放(fang)水時(shi)吸氣(qi)以利塔內存水順利放(fang)出,呼氣(qi)蒸(zheng)汽(qi)趕空氣(qi)時(shi),用(yong)以放(fang)凈空氣(qi),脫水放(fang)汽(qi)時(shi),用(yong)以檢查塔內是否(fou)為正壓。

GFD/Q多功(gong)能(neng)呼吸閥閥體的材質有:鑄鐵、鑄鋼(gang)、不銹(xiu)鋼(gang)、鋁(lv)合金。工(gong)作壓力0.6-6.4MPA，工(gong)作溫(wen)度-20°C-425C°。閥門口徑從 DN15-DN300。連接方式(shi):法蘭、對夾、絲口或焊接。

驅動(dong)方式(shi):手動(dong)、蝸(gua)輪、氣動(dong)、電動(dong)。

多功能呼(hu)吸(xi)閥適(shi)用介質:水、油品、氣、蒸(zheng)汽。主(zhu)要(yao)領域：化工設備、通用零部件、工業設備、制(zhi)藥(yao)設備、通用設備、石化設備。
