Press fitting device of valve body and valve seat of supercharging valve

The invention discloses a press fitting device of a valve body and a valve seat of a supercharging valve. The valve body is provided with a first through hole. The valve seat penetrates through the first through to be tightly matched with the valve body. The press fitting device comprises a centering structure. The centering structure is supported by the bottom of the base. The centering structure and the valve seat form a ball and plane pair. When the press fitting device of the structure exerts pressure on the valve body to achieve press fitting of the valve body and the valve seat, even if the force exerted on the valve body inclines in the vertical direction, it can be guaranteed that the valve body, the valve seat and the centering structure are centered. In this way, compared with traditional manual operation, the potential safety hazards are reduced. Meanwhile, personnel do not need to make contact with parts, and secondary pollution to the parts is not prone to happen. The force exerted by the press f
