　　Ball valve is a widely used valve equipment, which is widely used in various fields such as petroleum, chemical, power, metallurgy, and steel. Ball valves are mainly used on pipelines to cut off, distribute, and change the direction of medium flow. The opening and closing component of a ball valve is a sphere, which rotates 90 degrees around the axis of the valve shaft to achieve the purpose of opening and closing. The sealing of existing ball valves is achieved by squeezing the valve seat with a ball, but the material hardness of the existing valve seat is high and the rebound is poor. In order to achieve valve sealing, it is necessary to increase the valve interference fit, which results in high valve torque, increases the overall cost of the valve, and leads to a relatively short service life of the valve.
