Hammer flip valveThe valve plate of the heavy hammer tilting valve opens automatically under the action...The ventilation butterfly valve is divided into manual and electric transmission, which can be driven by an electric motor or a turbine to drive the actuator, so that the butterfly plate can freely rotate within 90° to achieve the purpose of opening and closing or regulating the flow of medium.
Because the gap between the butterfly valve and the valve body is large, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by temperature changes, and will not produce the phenomenon of dead butterfly plate.Common butterfly valve has a variety of driving modes, manual drive, electric drive and pneumatic drive, etc., the choice of the very large.Because of the material, this butterfly valve also has the characteristics of high temperature resistance, when the switch will not have friction, the service life is very long.Ventilation butterfly valve is a kind of valve made of steel plate welding, it has the characteristics of small size, light weight and easy to install, and because of its small flow resistance, flow flux, will not be affected by high temperature expansion.Its drive torque is small, the switch is very flexible, so it is very easy to operate.By the industry insiders love.
The structure of the ventilation butterfly valve is welded by the middle line butterfly plate and the short structure steel plate, so there is no connecting rod and bolt and other components inside it, and some component problems will not occur in the use process, so the failure rate is very low.It's easy to use.It is a reliable valve device.And because its sealing system is closed by metal, although the sealing effect is not as good as the elastic seal, but the service life is longer than the elastic seal, and has the characteristics of high temperature resistance.So in building materials, electric power, metallurgy and other industries have a wide range of applications.In the temperature is not higher than 300 degrees in the medium transmission pipeline, can realize the connection and close regulation.This butterfly valve can also be customized according to the needs of customers, very human.
