Description

Technical Field

[0001] The utility model relates to the field of valves, and more specifically, it relates to a ball valve filtering structure. Background Art

[0002] In the market, as a common fluid control device, the ball valve of the valve is widely used in fields such as petroleum, chemical industry, and water treatment. It realizes the on-off or flow regulation of the fluid through the rotation of the ball. In practical applications, the fluid often contains impurities or particulate matters. If it directly enters the interior of the ball valve, it may cause wear of the sealing surface, damage to the valve seat, or jamming of the ball, thereby affecting the sealing performance and service life of the valve. Existing ball valves usually adopt an external filtering structure (such as a pre-filter or a filter screen) to intercept impurities in the fluid.

[0003] In the field of valves, the impurity filtration of the valve system has always been a key issue affecting the reliability and service life of the equipment. In traditional designs, the filter screen is usually directly installed at the valve inlet. Although this structure can effectively protect the internal components of the valve, there are obvious defects in actual operation: when the valve is opened, the fluid will directly impact the filter screen, and the filter screen is subjected to a large impact and is easily damaged. And when this situation occurs, the valve and the pipeline are usually already connected, so it is difficult to replace. Therefore, a filtering structure that can reduce the impact on the filter is needed. Summary of the Utility Model
