  輕型手(shǒu)動蝶閥(fá)，普遍适(shi)用于建(jian)材、玻璃(li)、礦山、電(dian)力、輕工(gong)🚩、造紙等(děng)行業的(de)通風、環(huán)保工程(chéng)等管道(dào)系統中(zhōng)。對管道(dào)中氣體(tǐ)介質按(an)✊不同控(kong)制信号(hào)調節流(liu)量大小(xiao)😘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.

Structure characteristic:

  輕型(xing)手動蝶(die)閥，采用(yòng)優質碳(tan)素鋼焊(hàn)接。具有(yǒu)重量輕(qīng)、結🌂構簡(jian)🥰單⭐、流阻(zu)損失小(xiǎo)、操作靈(ling)活、指示(shì)方位明(míng)确、維護(hù)方🔞便、使(shǐ)用壽命(mìng)長、可任(rèn)意安裝(zhuang)等優點(dian)。配用蝸(wō)輪傳動(dong)裝置切(qiē)換，開關(guan)輕☀️松自(zì)如🔆,任意(yi)調節閥(fa)門開度(dù),是調節(jiē)流量的(de)理想設(she)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.
