(Summary description)As a component used to realize the on-off and flow control of the pipeline system, the butterfly valve has been extremely widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. In the well-known butterfly valve technology, its sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitation of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance.

The structure of the butterfly valve and the problems in the use process
As a component used to realize the on-off and flow control of the pipeline system, the butterfly valve has been extremely widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. In the well-known butterfly valve technology, its sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitation of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance.

Treatment of Deflection and Deformation of Large Butterfly Valve Guide
In order to solve the gap between the main and auxiliary butterfly plates of the water intake valve, the deflection of the four guide posts must be eliminated. The water intake valve is installed inside the dam body, and there is no working platform in the valve chamber, and the site does not have the conditions for replacement and hot riveting to assemble the guide post. Since the deflection angle of the guide column is very small and there is no crack in the column body, the method of grinding the part of the guide column that deviates from the normal contour instead of dealing with the part of the normal contour is used to deal with the deflection and deformation defects of the guide column.
