Description
Technical Field
The utility model particularly relates to a two eccentric spraying aluminium oxide butterfly plates.
Background
At present, butterfly valves are widely used in many fields such as petroleum, chemical engineering, metallurgy, and hydroelectric power as a component for realizing the on-off and flow control of pipeline systems. In the pipe network, the butterfly valve replaces the heavy, bulky, big gate valve of opening and closing power with simple structure, small, light in weight, opens and close convenient, rapid, laborsaving advantage. The valve plate of the existing butterfly valve swings due to oscillation to cause the butterfly plate and the valve rod to loosen, so that leakage is generated. A large amount of tap water flows outwards, water sources are wasted, and normal operation of a pipe network cannot be guaranteed.
