[0002] A ball valve is a valve that closes and opens the flow of fluid, primarily through a rotating ball. Ball valves are widely used in various piping systems due to their simple structure, good sealing performance, and low flow resistance.

[0003] However, traditional ball valves still have some problems when in use: the lack of a filtering mechanism cannot effectively filter impurities in the fluid in the pipeline, which can easily cause blockage and failure. In addition, some ball valves require an external filtering mechanism, which increases the overall installation space of the ball valve. Therefore, we propose a ball valve with a filtering function to solve the above problems. Utility Model Content
