风道止回阀-湖北澳星环保成套设备有限公司手机版

详细介绍

风道止回阀广泛适用于建材、矿山、电力、轻工、玻璃等行业的通风管路系统中，进行气流单向调节及逆向截止。

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.

结构特点：

Structure characteristic:

风道止回阀结构设计新颖，传动，运行灵活，体积小，重量轻。当通风时，由风压而使其开启，停止逆风时，由于叶片与重锤的重力，阀板自行关闭，通过调整重锤的位置来调整气流量。T303P-1风道止回阀装在水平管道上，为圆法兰连接，T303P-2为方法兰连接，T303C-1风道止回阀装在垂直管道上（无重锤），为圆法兰连接，T303C-2为方法兰连接。

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.
