  輕型(xíng)手動蝶閥，普遍(biàn)适用于建材、玻(bo)璃、礦山、電力、輕(qing)🔴工⛷️、造紙💯等行☔業(yè)的通風、環保工(gōng)程等管道系統(tǒng)中。對管道中氣(qi)體介質按不同(tong)控制信号調節(jiē)流量大小和切(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.

結構特點：

Structure characteristic:

  輕(qing)型手動蝶閥，采(cǎi)用優質碳素鋼(gāng)焊接。具有重量(liang)輕、結構♌簡單、流(liú)阻損失小、操作(zuò)靈活、指示方位(wei)明确、維護方便(biàn)、使用壽👅命長、可(kě)任意安裝等優(you)點。配用蝸輪傳(chuan)動裝🈲置切換，開(kai)關輕松自如,任(ren)意調節閥門開(kāi)度🌈,是調節流😘量(liang)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.
