輕型手動(dòng)蝶閥，普遍適用于建材、玻璃、礦山、電力、輕工、造紙等行業(yè)的通風(fēng)、環(huán)保工程等管道系統(tǒng)中。對(duì)管道中氣體介質(zhì)按不同控制信號(hào)調(diào)節(jié)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(jié)構(gòu)特點(diǎn)：
Structure characteristic:
輕型手動(dòng)蝶閥，采用優(yōu)質(zhì)碳素鋼焊接。具有重量輕、結(jié)構(gòu)簡(jiǎn)單、流阻損失小、操作靈活、指示方位明確、維護(hù)方便、使用壽命長(zhǎng)、可任意安裝等優(yōu)點(diǎn)。配用蝸輪傳動(dòng)裝置切換，開關(guān)輕松自如,任意調(diào)節(jié)閥門開度,是調(diào)節(jié)流量的理想設(shè)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.
