Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a pneumatic fluorine-lined discharging ball valve. Background Technique

[0002] A fluorine-lined ball valve uses a sphere with a circular through-hole as the opening and closing part. The sphere rotates around the center line of the valve body with the valve stem to realize the opening and closing of the valve, and can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between the V-type ball core and the metal valve seat surfacing with hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. At present, there is no filtering structure inside the ball valve. After the ball valve is used for a long time, more particulate matters will be adsorbed on the inner wall of the valve body and the surface of the sphere. When the particulate matters accumulate too much, the permeability of the ball valve will be reduced, resulting in unsmooth discharge of materials. However, the disassembly and maintenance of the ball valve are troublesome and cumbersome, affecting the efficiency of disassembly and maintenance, and also affecting the service life of the ball valve.

[0003] As in the prior art, the Chinese utility model content with the publication number: CN220302807U discloses a pneumatic fluorine-lined discharging ball valve, including a valve body and a cylinder. The bottom of the cylinder is connected with a transmission box, the transmission box is fixed on the top of the valve body, and a sphere is rotatably fixed inside the valve body, and the sphere is connected with the transmission box. This utility model is provided with a limiting ring and a scraping strip. The scraping strip is rotatably fixed inside the sphere through the limiting ring. When the ball valve needs to be cleaned, the sewage discharge cover on the side of the valve body can be opened, and then the scraping strip is rotated to scrape off the sundries adhered to the inner wall of the sphere, and the sundries are discharged from the sewage discharge cover. Through this setting, there is no need to disassemble and clean the whole valve body, and the cleaning process is simple, fast and labor-saving. The filter box can filter the particulate matters in the fluid to prevent the particulate matters from blocking the inside of the valve body. By providing a brush plate located outside the filter cylinder, the handle can be rotated to make the brush plate brush off the particulate matters outside the filter cylinder, thereby preventing the filter cylinder from being blocked.

[0004] However, although the above pneumatic fluorine-lined discharging ball valve can filter the particulate matters inside the fluid and reduce the blockage of the inside of the valve body by the particulate matters, during use and maintenance, affected by the external filter box, when the filter cylinder is damaged, it is inconvenient to disassemble and maintain the filter cylinder, and there is a certain inconvenience in replacement. Therefore, we need to propose a pneumatic fluorine-lined discharging ball valve. Content of the Utility Model
