風道止(zhǐ)回閥廣泛适(shi)用于建材、礦(kuang)山、電力、輕工(gōng)、玻璃😘等行💛業(ye)的通風管路(lù)系統中，進行(hang)氣流單向調(diào)節及逆向截(jie)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(diǎn)：

Structure characteristic:

  風道止回閥(fa)結構設計新(xīn)穎，傳動獨特(te)，運行靈活，體(tǐ)積小，重量輕(qing)。當通風時，由(you)風壓而使其(qí)開啟，停止逆(ni)風時，由于葉(yè)片與重錘的(de)重力，閥闆自(zi)行關閉，通過(guò)調整重錘的(de)位置來調整(zheng)氣流量。T303P-1風道(dào)止回閥裝在(zai)水平管道上(shang)，為圓法蘭連(lian)接，T303P-2為🧑🏽‍🤝‍🧑🏻方法蘭(lan)連接，T303C-1風道止(zhi)回閥裝在垂(chui)直管道上（無(wu)重錘），為圓法(fǎ)蘭連接，T303C-2為方(fang)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.
