輕型手動蝶閥，普遍适用于建材、玻璃、礦山、電力、輕工、造紙等行業的通風、環(huán)保工程等管道系統中。對管道中氣體介質按不同(tóng)控制信号調節流量大小和切斷。
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:
輕型手動蝶閥，采用優(yōu)質(zhì)碳素鋼焊接。具有重量輕、結構(gòu)簡單、流阻損失小、操(cāo)作靈活、指示方位明确、維護方便、使(shǐ)用壽命長、可(kě)任意(yì)安裝等優(yōu)點。配用蝸輪傳動裝置切換，開關輕(qīng)松自如,任意調節閥(fá)門開(kāi)度,是調節流量的理想(xiǎng)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.
