Description
Technical Field
The utility model relates to a valve equipment field specifically is a wafer formula amortization butterfly valve.
Background
A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve with a closing member which is a disc and rotates around a valve shaft to open and close. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved.
The current butterfly valve has high noise and is not resistant to high temperature, so that aiming at the current situation, the butterfly valve with low noise and high temperature resistance needs to be developed urgently to overcome the defects in the current practical application and meet the current requirements.
