輕型(xíng)手動蝶閥(fá)，普遍适(shì)用(yòng)于建(jiàn)材、玻(bō)璃、礦山、電(diàn)力、輕(qīng)工、造(zào)紙等行業(yè)的通風、環保工程(chéng)等管道系統中。對管道(dào)中氣體(tǐ)介(jiè)質按不同控制信号(hào)調節流量(liàng)大小和切(qiē)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(tè)點：
structure characteristic:
輕型(xíng)手動蝶(dié)閥，采用(yòng)優質碳素鋼(gāng)焊接(jiē)。具有重量(liàng)輕(qīng)、結(jié)構簡(jiǎn)單、流阻損(sǔn)失小(xiǎo)、操作靈(líng)活、指示(shì)方位明确(què)、維(wéi)護(hù)方便(biàn)、使用(yòng)壽命長、可任意安裝(zhuāng)等優點。配用蝸(wō)輪(lún)傳動裝置切換，開關(guān)輕松自(zì)如,任意調節閥門開度,是(shì)調節(jiē)流量的理想設備。
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.
