Beschreibung
Zusammenfassung:	The utility model discloses a sealing anti-leakage ball valve structure which comprises a ball valve body, a first sealing assembly and a second sealing assembly, the top end of the ball valve body is rotationally connected with a valve rod used for rotating a ball body in the ball valve body, a feeding end is arranged on the left side of the ball valve body, and a discharging end is arranged on the right side of the ball valve body. The first sealing assembly is used for sealing the position of the valve rod, the first sealing assembly is located on the outer side of the valve rod, the second sealing assembly is used for sealing the position of the feeding end and the position of the discharging end, and the second sealing assembly is located on the surface of the feeding end and the surface of the discharging end. The first sealing ring can be attached to the ball valve body all the time, so that the situation that after long-time use, a gap is likely to occur between the first sealing ring and the ball val
