手動翻闆式三杆蝶閥，廣泛(fàn)适用于建材、玻璃、礦(kuàng)山(shān)、電力、輕工、造紙等行業(yè)的能源輸送管道的煤氣、天(tiān)然氣、通風、環保工程等管道(dào)系(xì)統中。對管道中氣體介質(zhì)按不同控制信(xìn)号調節流(liú)量大小和切斷。

  This valve is widely used in the pipe system transporting coal gas, natural gas, venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. The technique is introduced from foreign Company. It can change the flow and cut off gas medium in the pipe by the different control signal.

結構特點(diǎn)：

Structure characteristic:

  手動翻闆式三杆(gǎn)蝶閥具有結構獨(dú)特、耐磨損、流阻損失小、密封性強、自(zì)鎖性可靠、操作靈活、指示方位明确(què)、維護方便、密封面無磨損、使用壽命(mìng)長(zhǎng)等優點，尤其傳(chuán)動軸部分采用外部密封，易調整、易更換無需停機，從而有效地杜絕(jué)外漏。采用多種密封形式能适應不同(tóng)的介質，特别适用于調(diào)節切斷和要求快速自保的場合。配用蝸輪傳動裝置，可實現啟閉操作，是調節流量(liàng)的理想設備。

  The valve has the features of compact structure, endurance, little in the lost of flow resistance, good seal, reliable self-locking, flexible operation, definite direction, easy to maintenance and long life. The seal of driving shaft is out seal, which is easy to be adjusted and changed without stopping, so the out leakage is avoided effectively. All kinds of seal type can suit different medium. It is especially suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with worm gear driving device to form a complete set to realize open-close operation. It is the ideal equipment of adjusting flow.
