Full fluorine-lined ball valve

The utility model discloses a full fluorine-lined ball valve, relates to the field of fluorine-lined valves, and solves the problem of leakage caused by floating of a ball body. The lower valve rod is fixedly connected with the ball body, the lower valve rod is sleeved with a rod outer lining layer integrally connected with the fluorine lining, the rod outer lining layer covers the peripheral wall of the lower valve rod, the periphery of the rod outer lining layer is further movably sleeved with a plastic shaft sleeve, the plastic shaft sleeve and the lower valve rod are coaxially arranged, and the plastic shaft sleeve is installed between the fluorine lining of the left valve body and the fluorine lining of the right valve body in a limited mode. The arrangement of the lower valve rod can greatly reduce the floating amplitude of the ball body, reduce the offset of the ball body, prevent the ball body from extruding the valve seat on the downstream side due to over-long acting force of a medium, reduce the da
