風道止回(hui)閥廣泛适(shi)用于建材(cai)、礦山、電力(li)、輕工、玻璃(li)等❤️行業的(de)通☀️風管路(lu)系統中，進(jin)行氣流單(dan)向調節及(ji)🧡逆向截止(zhi)。

  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(dian)：

Structure characteristic:

  風道止回(hui)閥結構設(she)計新穎，傳(chuan)動獨特，運(yun)行靈活，體(ti)積小📞，重😘量(liang)輕。當通風(feng)時，由風壓(ya)而使其開(kai)啟，停止逆(ni)風時，由于(yu)葉片與重(zhong)💘錘的重力(li)，閥闆自行(hang)關閉，通過(guo)調整重錘(chui)的位置來(lai)調整氣流(liu)量。T303P-1風道止(zhi)回閥裝在(zai)水平管道(dao)😘上，為圓法(fa)蘭連接，T303P-2為(wei)✍️方法蘭連(lian)🤞接，T303C-1風道止(zhi)回閥裝在(zai)垂直管道(dao)上（無重錘(chui)），為圓法蘭(lan)連接，T303C-2為方(fang)法蘭連接(jie)。

  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.
