Application and principle of electric ventilation butterfly valve

更新時(shí)間:2018.07.20
Electric ventilation butterfly valve work is driven by a motor to drive actuators, make the disc plate freely within the range of 90 ° rotation to achieve the goal of open/close or adjusting medium flow.
At present, fluorine - lined butterfly valve, rubber - lined butterfly valve, as a component used to realize pipeline system on - off and flow control, has been widely used in petroleum, chemical industry, metallurgy, hydropower and many other fields. In the butterfly valve technology known to the public, its seal form mostly USES the sealing structure, the sealing material is rubber, polytetrafluoroethylene and so on.
Due to the limitation of structural characteristics, it is not suitable for high temperature, high pressure, corrosion and wear resistance industries. Currently, a relatively advanced butterfly valve is a three-eccentricity metal hard sealing butterfly valve. The body and seat are connected components. The multi-layer soft-stack sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, this kind of electrically ventilated butterfly valve has the advantages of high temperature resistance, light operation and no friction on opening and closing. It is used in industrial, metallurgy, environmental protection and other pipelines for ventilation and adjustment of medium flow. It has the characteristics of simple structure, light weight, small operating torque, quick opening and closing, flexible movement, large circulation capacity and high adjustment precision. It is suitable for the regulation and control of flue gas, dust, air or suspension and fluid, thick turbidity and slurry fluid.
