Ventilation butterfly valve used in chemical industry, building materials, ventilation, environmental protection engineering in power plant, glass and other industries of dust in the cold or hot gas pipeline, the gas medium to adjust flow or cut off the pipeline control unit. Then we shall generally be installed in this type of valve in the pipeline. Ventilation butterfly valve structure as shown in the following: the first. Adopted the midline type disc plate and short structure is a new type of structure design and manufacture of the steel plate welding, compact structure, light weight, easy installation, small flow resistance, big circulation, avoid the influence of high temperature expansion, convenient operation. In the second. No the connecting rod, bolts, etc. , reliable operation, long service life. Can transfer installation, not affected by the medium flow ventilation butterfly valve USES: ventilation butterfly valve is a kind of closed type butterfly valve, widely used in building materials, metallurgy, mining, power and other production process of medium temperature & le; 300 ℃ nominal pressure of 0. A line 1 mpa, to connect and open/close or adjusting medium quality.
