Ventilation butterfly valve is a control device that is widely 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. It is used as a gas medium to regulate flow or cut off pipeline control. . The ventilation butterfly valve is made of the same material as the valve body and is processed into a sealing ring. Its applicable temperature depends on the material selection of the valve body and the nominal pressure. It is generally suitable for ventilation and regulating medium flow in industrial, metallurgical, environmental protection and other pipelines. Its main features are novel and reasonable design, unique structure, light weight and rapid opening and closing.
The operating torque is small, the operation is convenient, labor-saving and dexterous.
Adopt suitable materials to meet different medium temperatures of low, medium and high, as well as corrosive media, etc.
Structural features of ventilation
Butterfly valve
It is designed and manufactured using a new structural form welded by centerline disc and short structural steel plate. It has compact structure, light weight, easy installation and flow. Small resistance, large circulation, avoid the influence of high temperature expansion, easy to operate, no connecting rods, bolts, etc. inside, reliable operation and long service life. It can be installed at multiple stations and is not affected by the flow direction of the medium
The ventilation butterfly valve is made of steel plate welding. It has the characteristics of short structural size, light weight and easy installation. It is widely used in metallurgy, chemical industry, electric power, building materials, mining and other industries. The pipeline controls or regulates the medium gas. The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent jamming caused by thermal expansion and contraction. This valve can be equipped with a variety of driving devices, such as manual devices and worm gear transmissions. Device, pneumatic device, electric device ventilation butterfly valve.
