  手動通風(feng)蝶閥，普遍适(shi)用于建材、玻(bo)璃、礦山、電力(lì)、輕工、造紙✏️等(deng)行業的通風(fēng)、環保工程等(děng)管道系統中(zhong)。

  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.

結構特點：

Structure characteristic:

  手(shǒu)動通風蝶閥(fa)，采用優質碳(tan)素鋼焊接。具(jù)有結構合理(li)、耐磨損、流🔞阻(zu)損失小、操作(zuò)靈活、指示方(fang)位明确、維護(hù)方♉便、使用壽(shòu)命長等優點(diǎn)。可水平安裝(zhuāng)或垂直安裝(zhuang)。配用蝸輪傳(chuán)動裝置,開關(guān)輕松自如,任(rèn)意調節閥門(mén)開度,是調節(jie)流量的理想(xiǎng)設備。

  The valve is welded in fine carbon steel, having the features of compact structure, endurance, little in the lost of flow resistance, definite direction, easy to maintenance and long life. It can be installed in horizontal or vertical. 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.
