[0001] The invention relates to the technical field of ball valves, in particular to a ball valve with a sterilization function. Background Art

[0002] A ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing. It is particularly suitable for media containing fibers, tiny solid particles, etc. Ball valves are widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries.

[0003] The existing ball valve has a relatively simple function and can generally only be used for fluid regulation and control. The medium will be mixed with some bacteria during the flow process and the quality is not high. If you want to achieve the function of sterilization and disinfection, you generally need to use an ultraviolet lamp. However, the ultraviolet lamp is in contact with the medium for a long time and its surface needs to be cleaned regularly. The ultraviolet lamp is generally inside the valve body, which is troublesome to clean. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention
