上海(hai)閥(fa)(fa)(fa)盛閥(fa)(fa)(fa)門制造有限(xian)公司(si)主要(yao)生產多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)，可提(ti)供多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)價格，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)說明書，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)實物(wu)圖(tu)，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)結構圖(tu)，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)外形尺寸，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)執行標準，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)工作原理，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)(hu)吸(xi)閥(fa)(fa)(fa)作用(yong)特(te)點。

GFD/Q多功能阻(zu)火呼(hu)吸閥類似(si)于單向(xiang)(xiang)止逆閥,它只能向(xiang)(xiang)外呼(hu)氣(qi),不能向(xiang)(xiang)內吸氣(qi),當(dang)系統內壓(ya)力升高時(shi),氣(qi)體便經過向(xiang)(xiang)外放空,保證(zheng)系統的壓(ya)力恒定。一般(ban)它被用在常壓(ya)或低壓(ya)貯罐上。

焦(jiao)炭塔(ta)的呼吸閥有兩個用處(chu)：放水時(shi)吸氣(qi)以(yi)利塔(ta)內存(cun)水順(shun)利放出,呼氣(qi)蒸汽趕空氣(qi)時(shi),用以(yi)放凈(jing)空氣(qi),脫(tuo)水放汽時(shi),用以(yi)檢(jian)查塔(ta)內是(shi)否為正壓。

GFD/Q多功能呼吸閥閥體的材(cai)質有:鑄鐵、鑄鋼(gang)、不銹鋼(gang)、鋁合金。工作(zuo)壓力(li)0.6-6.4MPA，工作(zuo)溫度-20°C-425C°。閥門口徑從 DN15-DN300。連接方式(shi):法蘭、對夾、絲(si)口或焊接。

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

多功能(neng)呼吸閥適用介質:水、油品、氣、蒸汽(qi)。主要領域(yu)：化工設備、通(tong)用零部件、工業設備、制藥設備、通(tong)用設備、石化設備。
