What are the structural characteristics of the ventilation butterfly valve?

Valves have different effects according to their structure. Today, let the editor of Tianjin butterfly valve manufacturer show you the structural characteristics of ventilation butterfly valve.   Ventilation butterfly valve is a valve made of steel plate welding. It has the characteristics of small size, light weight and easy installation, and because of its small flow resistance and large flow, it will not be affected by high temperature expansion. Its driving torque is small and the switch is very flexible, so it is very convenient to operate. It is deeply loved by people in the industry.   The structural characteristics of the ventilation butterfly valve. The structure of the ventilation butterfly valve is welded by the centerline butterfly plate and the short structural steel plate, so there are no components such as connecting rods and bolts inside, and there will be no components during use. Problem, so the failure rate is very low. It is very convenient to use. It is a reliable valve device.   And because its sealing system uses metal sealing, although the sealing effect is not as good as the elastic seal, the service life is longer than that of the elastic seal, and it has the characteristics of high temperature resistance. Therefore, it is widely used in building materials, electric power, metallurgy and other industries. In the medium conveying pipeline whose temperature is not higher than 300 degrees, the connection and closing adjustment function can be realized. This butterfly valve can also be specially customized according to the needs of customers, which is very user-friendly.   Because the gap between the butterfly plate and the valve body of the ventilation butterfly valve is large, there is enough room for expansion, so it can effectively prevent thermal expansion and contraction caused by temperature changes during use, and it will not produce butterfly The board is stuck. Common butterfly valves have a variety of drive methods, including manual drive, electric drive and pneumatic drive, etc., and the choice is very large. Because of the material, this butterfly valve also has the characteristics of high temperature resistance, there is no friction when switching, and the service life is extremely long.
