風道止回(huí)閥廣泛适用(yong)于建材、礦山(shan)、電力、輕工、玻(bō)璃等❗行業的(de)通風管路系(xì)統中，進行氣(qì)流單向調節(jiē)及逆向截止(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：

Structure characteristic:

  風(feng)道止回閥結(jié)構設計新穎(yǐng)，傳動獨特，運(yùn)行靈活，體積(ji)小，重🔞量輕。當(dāng)通風時，由風(fēng)壓而使其開(kāi)啟，停止逆風(feng)時⭕，由于葉片(piàn)☁️與重錘的重(zhong)力，閥闆自行(hang)關閉，通過💃調(diao)整重📧錘的位(wei)置來調🧡整氣(qì)流量。T303P-1風道止(zhǐ)回閥裝在水(shui)平管道上，為(wei)圓法蘭連接(jiē)，T303P-2為方法蘭連(lián)🌏接，T303C-1風道止⭐回(huí)閥裝在垂直(zhi)管道上（無重(zhòng)錘），為圓法蘭(lan)連接，T303C-2為方法(fa)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.
