手動翻闆(pan)式三杆蝶閥，廣泛(fan)适用于建材、玻璃(lí)、礦山、電力、輕工、造(zào)紙等行業的能源(yuán)輸送管道的煤氣(qì)、天然氣、通風、環保(bǎo)工程等管道系統(tǒng)中。對管道中氣體(tǐ)👉介質按不同控制(zhì)信号調節流量大(da)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.

Structure characteristic:

  手動翻闆式三(san)杆蝶閥具有結構(gou)獨特、耐磨損、流阻(zu)損⛷️失小、密♈封❄️性強(qiang)、自鎖性可靠、操作(zuo)靈活、指示方位明(míng)确、維護方便、密封(fēng)面無磨損、使用壽(shòu)命長等優點，尤其(qí)傳動軸部分采用(yong)🏃🏻外部密封，易調整(zheng)、易更換無需停機(ji)，從而有效地杜絕(jué)外漏🌐。采用多種密(mi)封形式能适應不(bu)同的介質，特别适(shi)用于調節切斷和(he)要求✨快速自保的(de)場合。配用蝸輪傳(chuan)動裝置，可實現啟(qi)閉操作，是調節流(liú)量的理想設備。

  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.
