[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0030] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] The present utility model provides a pneumatic V-ball valve. Please refer to Figures 1-4 , which includes a valve housing 100, an adjusting component 200, a ball valve component 300, and a filtering component 400;

[0032] Please continue to refer to Figures 1-2 , the valve housing 100 as a connecting base frame has a connecting frame 110 threadedly connected to the top thereof, and a valve seat (not marked in the figure) adapted to the ball valve 330 is connected to the inner side of the valve housing 100 corresponding to the position of the ball valve 330;

[0033] Please continue to refer to Figures 1-4 , the adjusting component 200 is connected to the connecting frame 110 to provide power to drive the ball valve component 300 to act inside the valve housing 100 and control the on-off state;

[0034] The adjusting component 200 includes a pneumatic actuator 210 threadedly connected to the top of the connecting frame 110, and a pneumatic telescopic rod 220 connected inside the connecting frame 110 and connected to the output end of the pneumatic actuator 210. A connecting seat 221 is provided at the end of the pneumatic telescopic rod 220, a sliding seat 230 is connected to the outside of the connecting seat 221, the sliding seat 230 is slidably connected inside the connecting frame 110, and a toothed plate 231 is connected to the outside of the sliding seat 230;

[0035] When the pneumatic telescopic rod 220 works, it drives the connecting seat 221 to act, and then drives the lateral position of the toothed plate 231 to change. Since the toothed plate 231 is in meshing transmission cooperation with the transmission gear 310, during the translation of the toothed plate 231, it will drive the valve stem 320 connected to the transmission gear 310 to act, and then change the direction of the ball valve 330 to achieve the control of the on-off state of the valve body. The connection method of gear meshing transmission has better stability;

[0036] Please continue to refer to Figures 3-4 , the ball valve component 300 is rotatably connected inside the valve housing 100, connected to the adjusting component 200, and acts synchronously with the adjusting component 200;

[0037] The ball valve component 300 includes a valve stem 320 rotatably connected inside the valve housing 100. A transmission gear 310 meshing and drivingly cooperating with a toothed plate 231 is connected to the top end of the valve stem 320. The bottom end of the valve stem 320 is connected to a ball valve 330 and drives the ball valve 330 to rotate inside the valve housing 100. An installation seat 321 is integrally formed at the bottom end of the valve stem 320. Multiple sets of embedding grooves 322 are formed at the bottom of the installation seat 321. An installation groove 331 adapted to the installation seat 321 is formed at the top of the ball valve 330. And an embedding seat 332 engaging and cooperating with the embedding grooves 322 is integrally formed in the installation groove 331. Scrapers 340 are respectively connected to the outer side of the ball valve 330 corresponding to the inlet and outlet ends of the semi-circular channel. The scrapers 340 are arranged in a semi-circular arc shape. During the opening and closing process of the ball valve 330, the particles on the inner wall surface of the valve housing 100 are scraped off by the scrapers 340, reducing the wear of the ball valve 330 and the valve seat sealing surface by the particles and improving the sealing performance.

[0038] The embedding seat 332 engages and cooperates with the embedding grooves 322 to connect the valve stem 320 and the ball valve 330. The engaging and cooperating connection method facilitates the separation or connection of the valve stem 320 and the ball valve 330, and is convenient for subsequent disassembly, replacement and other operations.

[0039] Please continue to refer to Figures 1-2 , to prevent impurities from accumulating in the internal channel of the valve housing 100, connection grooves 120 are formed at both ends of the valve housing 100. A filtering component 400 is connected in the connection grooves 120. The filtering component 400 includes a connecting plate 410 engaging and cooperating with the connection grooves 120. A filter mesh plate 420 is connected inside the connecting plate 410 corresponding to the position of the through hole. The medium passing through the valve body is assisted in filtering by the provided filter mesh plate 420, which can achieve the effect of filtering impurities and protecting the inside of the valve body.

[0040] Furthermore, a linkage snap spring switch 121 is connected to the outer side of the valve housing 100 corresponding to the position of the connection groove 120. Two sets of linkage clamping seats 122 are movably connected in the connection groove 120. The linkage clamping seats 122 are connected to the linkage snap spring switch 121 and move synchronously with the linkage snap spring switch 121. A clamping groove 411 engaging and cooperating with the linkage clamping seats 122 is formed on the outer side of the connecting plate 410.

[0041] Working principle: When the utility model is in use, the pneumatic telescopic rod 220 works, driving the connecting seat 221 to move, and then driving the lateral position of the toothed plate 231 to change. Since the toothed plate 231 is in meshing transmission cooperation with the transmission gear 310, during the translation process of the toothed plate 231, it will drive the valve rod 320 connected to the transmission gear 310 to move, and then change the direction of the ball valve 330, realizing the control of the on-off state of the valve body. The structure of link linkage is converted into the gear meshing transmission cooperation between the toothed plate 231 and the transmission gear 310, with better stability. Moreover, scraping plates 340 are respectively connected to the inlet and outlet ends of the semicircular channel corresponding to the outside of the ball valve 330. During the opening and closing process of the ball valve 330, the particles on the inner wall surface of the valve housing 100 are scraped off by the scraping plates 340, reducing the wear of the particles on the ball valve 330 and the sealing surface of the valve seat, and improving the sealing performance;

[0042] Meanwhile, the medium passing through the valve body is assisted in filtering by the arranged filter mesh plate 420, which can play the role of filtering impurities and protecting the inside of the valve body.

[0043] Although the present utility model has been described with reference to the embodiments above, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
