  輕型手動(dong)蝶閥，普遍适(shì)用于建材、玻(bō)璃、礦山、電力(lì)、輕工、造紙等(deng)行業的通風(feng)、環保工程等(děng)管道系統中(zhōng)。對管道中氣(qi)體介質按不(bu)同🧡控制信号(hào)調節流量大(da)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)構特點：

Structure characteristic:

  輕型(xing)手動蝶閥，采(cǎi)用優質碳素(sù)鋼焊接。具有(you)重量輕🧑🏾‍🤝‍🧑🏼、結構(gou)簡單、流阻損(sǔn)失小、操作靈(líng)活、指示方位(wèi)明确、維護方(fang)便、使用壽命(mìng)長、可任意安(ān)裝等優點。配(pei)用蝸輪🌈傳動(dong)裝置切換，開(kai)關輕松自如(rú),任意調節閥(fa)門開度👈,是調(diao)節流量的理(li)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.
