風道(dao)止回閥(fa)廣泛适(shì)用于建(jian)材、礦山(shan)、電力、輕(qīng)工、玻璃(li)等行業(ye)♻️的通風(feng)管路系(xì)統中，進(jìn)行氣流(liú)單向調(diào)節及✏️逆(nì)向🥰截止(zhǐ)。

  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(tè)點：

Structure characteristic:

  風道(dào)止回閥(fá)結構設(she)計新穎(yǐng)，傳動獨(dú)特，運行(hang)靈活，體(ti)積小，重(zhòng)量🤩輕。當(dāng)通風時(shi)，由風壓(yā)而使其(qi)開啟，停(tíng)止逆風(fēng)時，由于(yu)葉片與(yǔ)重🔞錘的(de)重力，閥(fá)闆自行(hang)關閉，通(tōng)過💯調整(zhěng)重💛錘的(de)位置來(lái)調整氣(qì)流📞量。T303P-1風(fēng)道止回(hui)閥裝在(zai)水平管(guan)道上，為(wei)圓法蘭(lán)連接，T303P-2為(wei)方法蘭(lán)連接，T303C-1風(fēng)道止回(huí)閥裝在(zai)垂直管(guan)道上（無(wu)重錘），為(wei)圓法蘭(lán)連接，T303C-2為(wei)方👄法蘭(lán)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.
