  輕型手(shǒu)動蝶閥，普遍适(shì)用于建材、玻璃(lí)、礦山、電力、輕✂️工(gong)、造紙等行👨‍❤️‍👨業的(de)通風、環保工程(chéng)等管道系統中(zhōng)。對管道中氣體(tǐ)介質按不同控(kòng)制信号調節流(liu)量大小和切斷(duan)。

  This valve is widely used in the pipe system such as venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal.

結構特點：

Structure characteristic:

  輕型(xíng)手動蝶閥，采用(yong)優質碳素鋼焊(han)接。具有重量輕(qing)、結💚構😄簡單、流阻(zǔ)損失小、操作靈(ling)活、指示方位明(ming)确、維護方便、使(shǐ)用壽命長、可任(ren)意安裝等優點(diǎn)。配用蝸輪🌈傳動(dong)裝🔴置切換，開關(guān)輕松自如,任意(yì)調節閥門開度(du),是調節流🔞量的(de)理想設備。

  The valve is welded in fine carbon steel, having the features of light weight, compact structure, endurance, little in the lost of flow resistance, definite direction, easy to maintenance and long life. It can be installed at any angle. The valve is used with worm gearing device to form a complete set to realize switching freely and adjusting open angle of valve arbitrarily. It is the ideal equipment of adjusting flow.
