Inner leakage prevention valve element structure

The invention discloses an anti-inner-leakage valve element structure, and relates to the technical field of valve elements, the anti-inner-leakage valve element structure comprises a valve seat provided with an inner cavity; the valve element assembly is arranged in the valve seat, and the valve element assembly is in running fit with the valve seat; the valve cage is arranged between the valve seat and the valve element assembly, and the valve cage is in contact fit with the valve seat and the valve element assembly; the sealing assembly comprises a first elastic piece arranged between the valve seat and the valve cage and a second elastic piece arranged between the valve element assembly and the valve seat. Through cooperation of the valve element assembly and the valve cage, friction between the ball valve element and a sealing piece can be reduced when the ball valve element rotates, and the service life is prolonged. In addition, the inner leakage rate of the valve element can be reduced by arranging th
