As a further description of the above technical solution:
the profiling sealing ring is in a horn shape.
As a further description of the above technical solution:
and an elastic air bag is filled in a gap between the profiling sealing ring and the inner wall of the valve body.
As a further description of the above technical solution:
the elastic sealing ring is formed by stacking a soft layer and a hard layer, the hard layer is in sliding connection with the profiling sealing ring, and the soft layer is propped against the surface of the sphere.
As a further description of the above technical solution:
the hard layer is provided with a plurality of guide posts, the guide posts are slidably arranged in the guide sleeve on the profiling sealing ring, the guide posts are sleeved with springs, and the springs are propped against the hard layer and the profiling sealing ring.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, the present utility model provides a technical solution: the valve with the anti-corrosion function comprises a valve body 1, a ball body 2, a valve rod 3, a profiling sealing ring 4 and an elastic sealing ring 5, wherein the ball body 2 is hinged in the valve body 1, the ball body 2 blocks a flow passage 6 in the valve body 1, a through hole 7 in the ball body 2 is communicated with the flow passage 6, the valve rod 3 is connected with the ball body 2, the profiling sealing ring 4 is arranged in the valve body 1, the profiling sealing ring 4 abuts against the surface of the ball body 2, the elastic sealing ring 5 is connected with the edge of the profiling sealing ring 4, and the elastic sealing ring 5 abuts against the surface of the ball body 2;
