截止閥閥門尺寸#特選借鑒

1、詳細介紹：國家標準法蘭截止閥的開閉是圓柱形襟翼，密封面是平面或圓錐形，襟翼沿流體中心線直線運動。國家標準截止閥僅適用于全開和全關，一般不控制流量，在定制時允許調(diào)整和節(jié)流。在標稱壓力1.6MPa-16.0MPa、作業(yè)溫度-29 550 的石油、化學、制藥、肥料、電氣工業(yè)等各種條件下切斷或打開管路介質(zhì)。驅(qū)動方式包括手動、齒輪傳動、電氣、氣動等。國家標準法蘭截止閥產(chǎn)品功能1、結(jié)構(gòu)簡單，制造和維護更加方便2、小作業(yè)日程，短開閉時間3、密封性好，密封面之間的摩擦力小，壽命長國家標準法蘭截止閥執(zhí)行標準設計規(guī)范：GB/T 12235結(jié)構(gòu)長度：GB/T 12221凸緣連接：JB/T 79測試和測試：JB/T
