管道伸縮器、止回閥類
風道止回閥

風道止回閥廣泛適用于建材、礦山、電力、輕工、玻璃等行業的通風管路系統中,進行氣流單向調節及逆向截止。

This valve is widely used in the venting pipe system in building material, mining, power, light industry and glass industries etc. it is used to adjust the air flow in single direction and stop in negative direction.

 

 

結構特點:

Structure characteristic:

風道止回閥結構設計新穎,傳動獨特,運行靈活,體積小,重量輕。當通風時,由風壓而使其開啟,停止逆風時,由于葉片與重錘的重力,閥板自行關閉,通過調整重錘的位置來調整氣流量。T303P-1風道止回閥裝在水平管道上,為圓法蘭連接,T303P-2為方法蘭連接,T303C-1風道止回閥裝在垂直管道上(無重錘),為圓法蘭連接,T303C-2為方法蘭連接。

The valve has the features of novel design, special transmission, flexible operation, small volume and light weight. The valve will be opened on the pressure of wind when ventilate. The valve disc will close automatically on the effect of blade and heavy hammer gravity when stop adverse wind. Adjust air flow amount by adjusting the position of heavy hammer. Type T303p-1 valve is installed on the horizontal pipe, which is round flange connection, type T303p-2 is square flange connection. Type T303C-1 valve is installed on the vertical pipe without heavy hammer, which is round flange connection, T303C-2 is square flange connection.
