Ventilation butterfly valve use:
Ventilated butterfly valve is a kind of non-sealed butterfly valve, which is widely used in pipelines with nominal pressure of 0.1Mpa in the production process of building materials, metallurgy, mining, power, etc. to connect, open and close or adjust the amount of medium.
The main performance of the ventilation butterfly valve:
Nominal pressure: 0.05~0.1Mpa Applicable temperature: -10~300°C, -30~500°C, Drive mode: Manual, Electric, Pneumatic, Hydraulic, Electrohydraulic Applicable medium: Dust gas, air, gas and Dust gas leak rate: <3%
Ventilation butterfly valve structure features:
1. The vented butterfly valve is made of welded steel plates and has the characteristics of short structure, light weight and easy installation. The valve has small drive torque, flexible opening and closing, and easy operation. The valve body is provided with an oil seal retaining ring, there is no visible gap between the seal pairs, and the leakage rate is small. The large expansion gap between the butterfly plate and the valve body can effectively prevent the phenomenon of seizing due to thermal expansion and contraction. The valve can be equipped with a variety of drive devices, such as manual devices, worm gears, pneumatic devices, and electric devices.
2, there is no connecting rod, bolts, etc., reliable, long service life. Can be installed in multiple stations without being affected by the flow of media.
