Description

Technical Field

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

[0002] Ball valves, whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve, can also be used for regulating and controlling fluids. 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 overlay, which is particularly suitable for media containing fibers, tiny solid particles, etc. The valve core of the hard-sealed ball valve is alloy steel spray welding, and the sealing ring is alloy steel overlay, so the hard-sealed ball valve will not produce too much wear when opening and closing. Ball valves are a common structure among valves, and ball valves can well control the on and off of gas or liquid flowing in the pipeline.

[0003] In some special environments, valves are equipped with filters for filtering. However, the filters of existing valves cannot adjust the filtering size and cannot meet the filtering needs in different situations. Different filters need to be replaced by disassembly to cope with different situations, which is cumbersome and time-consuming. Therefore, a ball valve filtering structure that is easy to adjust is needed. Utility Model Content
