上海閥盛(sheng)閥門制造有限公司(si)主(zhu)要(yao)生產HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥，可提供HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥價格，HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥說明(ming)書，HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥實物圖，HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥結(jie)構圖，HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥外形(xing)尺寸，HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥執(zhi)行標(biao)準，HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥工作原理，HXF-4接管式呼(hu)(hu)(hu)(hu)吸(xi)(xi)閥作用特點。

HXF-4接管式呼吸閥類似于單向(xiang)止逆閥,它只(zhi)能向(xiang)外呼氣(qi),不能向(xiang)內(nei)(nei)吸氣(qi),當系統(tong)內(nei)(nei)壓(ya)力(li)升高時(shi)(shi),氣(qi)體便經過向(xiang)外放空,保(bao)證(zheng)系統(tong)的壓(ya)力(li)恒定。一(yi)般它被用(yong)在常壓(ya)或低(di)壓(ya)貯罐上。焦炭塔的呼吸閥有兩個用(yong)處：放水時(shi)(shi)吸氣(qi)以(yi)利塔內(nei)(nei)存水順利放出,呼氣(qi)蒸汽趕(gan)空氣(qi)時(shi)(shi),用(yong)以(yi)放凈空氣(qi),脫水放汽時(shi)(shi),用(yong)以(yi)檢查塔內(nei)(nei)是否為正(zheng)壓(ya)。
