上海閥盛閥門制(zhi)造有限公司主要(yao)生產電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥，可提供電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥價格，電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥說(shuo)明書(shu)，電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥實物圖，電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥結構(gou)圖，電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥外形尺寸(cun)，電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥執行標準，電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥工作原理，電(dian)(dian)(dian)(dian)動(dong)耐(nai)(nai)(nai)磨截(jie)止(zhi)(zhi)(zhi)(zhi)閥作用特點。

電動(dong)耐(nai)磨截止閥的啟閉件是塞形的閥瓣，密封(feng)面(mian)(mian)呈(cheng)平面(mian)(mian)或錐(zhui)面(mian)(mian)，閥瓣沿流體的中(zhong)心線作直線運動(dong)。閥桿的運動(dong)形式(shi)，有(you)升(sheng)(sheng)降桿式(shi)（閥桿升(sheng)(sheng)降，手(shou)輪(lun)不升(sheng)(sheng)降），也有(you)升(sheng)(sheng)降旋轉桿式(shi)（手(shou)輪(lun)與閥桿一起(qi)旋轉升(sheng)(sheng)降，螺(luo)母設在閥體上）。電動(dong)耐(nai)磨截止閥只適用(yong)于全開和(he)全關，不允許作調節和(he)節流。
