Electric ventilation butterfly valve is composed of electric drive mechanism and valve.Electric actuator USES 220V or 380V power source as the power, drive valve circle butterfly plate in the valve body to do 90 degrees of rotation around the valve shaft, to start and close the valve, ventilation butterfly valve body is made of welding plate, simple structure.The medium is air, dust and other non-fluid media, belongs to the non-sealing butterfly valve, butterfly valve allows the leakage amount is usually less than 1%, widely used in industrial dust, high temperature flue gas pipeline.
Electric ventilation butterfly valve is designed and manufactured by using the new structure form of middle line plate and short structure plate welding, which is compact in structure, light in weight, easy to install, small flow resistance, large flow flux, to avoid the influence of high temperature expansion, and easy to operate.No connecting rod or bolt in the body, reliable operation and long service life.Can be multi - station installation, not affected by the flow of media.
Electric ventilation butterfly valve is mainly used in gold, chemical industry, building materials, power plant, glass and other industries in ventilation, environmental protection engineering dust containing cold air or hot air gas pipeline, as a gas medium to regulate flow or cut off device.The electric ventilation butterfly valve is designed and manufactured by using a new type of structure, that is, the center line plate and the short structure plate are welded together.Electric ventilation butterfly valve is an unsealed butterfly valve, suitable for building materials, metallurgy, mining, electric power and other production process medium temperature ≤300℃ nominal pressure of 0.1mpa on the pipeline, used to connect, open and close or adjust medium quality.
Characteristics of electric ventilation butterfly valve:
1. Novel design, reasonable structure, light weight, quick opening and closing.
2. electric ventilation butterfly valve operating torque is small, easy to operate, labor saving dexterity.
3. electric ventilation butterfly valve USES suitable materials to meet the low, medium and high temperature of different media and corrosive media.
4. The electric ventilation butterfly valve is designed and manufactured by using the new structural form of the midline disc plate and the short structural steel plate welding, which can avoid the influence of high temperature expansion and is easy to operate.
5. no connecting rod, bolts, reliable work, long service life.Can be multi - station installation, not affected by the flow of media.
