Butterfly dampers are used in dusty cold air or hot air pipelines in ventilation and environmental protection projects in chemical, building materials, power stations, glass and other industries, as a pipeline control device for regulating flow or cutting off gas media. This type of valve should generally be installed horizontally in the pipeline.
1. It is designed and manufactured by adopting a new structural form welded by centerline butterfly plate and short structural steel plate. It has compact structure, light weight, easy installation, small flow resistance, large flow rate, avoids the influence of high temperature expansion, and is easy to operate
2. There are no connecting rods, bolts, etc. inside, reliable operation and long service life. It can be installed in multiple positions without being affected by the flow direction of the medium.
The Structure of the Butterfly Damper
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 component problems during use, 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, it can realize the function of connecting and closing regulation. This kind of 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 space for expansion. This allows it to effectively prevent thermal expansion and contraction caused by temperature changes during use, ensuring that the butterfly plate does not get stuck. Common butterfly valves have a variety of drive methods, including manual drive, electric drive and pneumatic drive, etc. The choice is very large. Because of the material, this butterfly valve also has the characteristics of high temperature resistance, there will be no friction when switching, and the service life is extremely long. Ventilation butterfly valve is a valve made of steel plate welding. It has the characteristics of small size, light weight and easy installation. Moreover, because of its small flow resistance and large flow rate, 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 and loved by people in the industry.
