[0002] Ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceutical industry, water conservancy, electric power, municipal administration, steel industry and other industries, and play an important role in the national economy. Ball valves are mainly used for cutting off, distributing and changing the flow direction of medium in pipelines. Due to water quality, some liquids contain a large amount of particulate impurities, which not only wear out the internal part of the ball valve and reduce the sealing performance over a long period of time, but also affect the health of the water.

[0003] The existing self-cleaning ball valve usually sets a filter screen to filter the impurities in water, thereby realizing self-cleaning. However, the filter screen is covered with impurities after long-term use, and the existing device lacks a component for cleaning the impurities on the filter screen. In addition, the impurities on the filter screen are scraped by the scraping strip, and part of the impurities can easily squeeze out of the filter screen and enter the valve core side, thereby causing the impurities to be unable to be discharged outside the ball valve body, and when the ball valve is started again, the impurities are washed away with the flowing water, which still causes pipeline pollution and damage to the internal part of the ball valve.
