Use of ventilation type butterfly valve: The ventilated butterfly valve is a non-closed butterfly valve, which is widely used in pipelines with a nominal pressure of 0.1Mpa in the production process of building materials, metallurgy, mining, electric power, etc., for connecting, opening and closing or adjusting the amount of medium. Main performance of ventilated butterfly valve: Nominal pressure: 0.05~0.1Mpa Applicable temperature: -10~300°C, -30~500°C, Drive mode: manual, electric, pneumatic, hydraulic, electro-hydraulic. Suitable medium: dusty flue gas, air, gas and Dust gas leakage rate: <3% Structural features of the ventilated butterfly valve: 1. The ventilated butterfly valve is made of steel plate welding and has the characteristics of short structure, light weight and convenient installation. The valve has small driving torque, flexible opening and closing, and convenient operation. An oil seal retaining ring is arranged on the valve body, and there is no visible gap between the seal pairs, and the leakage rate is small. The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent the jamming caused by heat expansion and contraction. The valve can be equipped with a variety of driving devices, such as manual devices, worm gears, pneumatic devices, and electric devices. 2, no connecting rods, bolts, etc., reliable operation and long service life. Can be installed in multiple stations, independent of the flow of media.
