Description

Technical Field

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

[0002] As a common fluid control device, the ball valve in valves on the market is widely used in fields such as petroleum, chemical industry, and water treatment. It realizes the on-off or flow regulation of fluid through the rotation of the ball. In practical applications, the fluid often contains impurities or particulate matters. If directly entering 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, but this design has many deficiencies. First, the aperture of the filter screen of the external filter is fixed and cannot flexibly adjust the filtering accuracy according to the particle size or concentration of impurities in the fluid, resulting in poor adaptability. Second, the filter is usually independently installed outside the valve body. When replacing or cleaning, it is necessary to disassemble the pipeline or the valve, which is cumbersome to operate and may affect the normal operation of the system. In addition, the external filter increases the complexity and occupied space of the pipeline system, especially limited in applicability in a compact installation environment. Therefore, there is an urgent need for a filtering structure integrated inside the ball valve, with adjustable filtering ability and convenient maintenance, to solve the problems of fixed filtering performance and inconvenient replacement in the prior art.
