Description

Technical Field

[0001] This invention relates to the field of ball valve technology, specifically to a high-strength, corrosion-resistant ball valve. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their strong shearing force between the V-shaped ball core and the metal seat with hard alloy overlay, are particularly suitable for media containing fibers or small solid particles. Multi-port ball valves can flexibly control the merging, splitting, and switching of flow directions in pipelines, and can also close any channel while connecting the other two. These valves should generally be installed horizontally in pipelines. A ball valve consists of a valve body, valve stem, ball, and valve seat. The valve stem is connected to the ball, and rotating the valve stem opens and closes the ball. The ball is circular with a central through-hole to allow fluid to pass through. The opening and closing of the ball is achieved by rotating it. A sealing ring is typically installed on the side of the valve seat near the ball to ensure a tight seal between the ball and the seat, preventing fluid leakage.

[0003] In existing technologies, ball valves often accumulate dirt on their inner walls during use. This dirt reacts chemically with the valve body, leading to corrosion and affecting its service life. Furthermore, when the medium flows, it comes into direct contact with the flow channel, and impurities and particles in the medium can scour the valve body, further increasing corrosion and impacting its lifespan. Therefore, we propose a high-strength, corrosion-resistant ball valve. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] I. This invention uses a medium to drive the vortex fan to rotate, which in turn drives the rotating shaft to rotate. The limiting rod causes the outer wall of the limiting wheel to fit into the groove. The groove limits the position of the limiting wheel, and the limiting wheel reduces friction. As the vortex fan rotates, under the action of centrifugal force, the three sliding rods move away from the rotating shaft. When the sliding rods move, they drive the connecting frame. When the limiting wheel rotates, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the driving gear. The driving gear drives the driven gear through its teeth. The driven gear drives the cleaning brush to rotate. Thus, the cleaning brush rotates around the rotating shaft and also rotates on its own axis. The cleaning brush can clean the impurities adhering to the inner wall of the valve body, preventing medium residue from adhering to the flow channel of the valve body, reducing corrosion of the valve body, and extending the service life of the valve body.

[0020] Second, this invention filters impurity particles in the medium using a filter cartridge, preventing these particles from eroding the valve body and improving its service life. Because the cross-shaped limiting block and the cross-shaped limiting groove are engaged, when the rotating shaft rotates, the cross-shaped limiting block drives the sliding shaft to rotate, which in turn drives the mounting base to rotate. The mounting base then drives the scraper to clean the impurity particles filtered by the filter cartridge, thus preventing impurity particles from adhering to the filter cartridge and avoiding filter cartridge blockage. Furthermore, under the pull of the second tension spring, the sliding shaft and the rotating shaft remain connected, increasing the stability of the structure. Attached Figure Description

[0031] Please see Figure 1-8 This invention provides a technical solution: a high-strength corrosion-resistant ball valve, comprising a cleaning assembly 101, which includes a rotating shaft 11, three limiting rods 12, a sliding rod 13, a cleaning brush 14, two fixing sleeves 16, a vortex fan 17, a sliding groove 18, a driven gear 19, a first tension spring 20, two guide rods 21, a driving gear 22, two limiting rings 31, a valve body 32, two limiting wheels 35, a groove 36, a rotating rod 37, and two connecting brackets 38;

[0032] The outer walls of the two limiting rings 31 are symmetrically fixed to the inner wall of the valve body 32. A groove 36 is formed on the inner wall of the limiting rings 31. The opposite ends of the three limiting rods 12 are symmetrically fixed to the outer wall of the fixing sleeve 16. A sliding groove 18 is formed inside the limiting rods 12. The two ends of the guide rod 21 are symmetrically fixed to both sides of the inner wall of the sliding groove 18. A first tension spring 20 is sleeved on the outer wall of the guide rod 21. A sliding rod 13 is slidably connected to the outer walls of the two guide rods 21. A vortex fan 17 is fixedly connected to... Two fixed sleeves 16 are symmetrically fixedly connected to the outer wall of the rotating shaft 11. The limiting wheel 35 is rotatably connected to the end of the limiting rod 12 away from the fixed sleeve 16.

Under the action of centrifugal force, the three sliding rods 13 move away from the rotating shaft 11. When the sliding rods 13 move, they drive the connecting frame 38. Since the limiting wheel 35 is in contact with the inner wall of the groove 36, the limiting wheel 35 rotates. When the limiting wheel 35 rotates, it drives the rotating rod 37 to rotate. When the rotating rod 37 rotates, it drives the driving gear 22. The driving gear 22 drives the driven gear 19 through its teeth. The driven gear 19 drives the cleaning brush 14 to rotate. Then the cleaning brush 14 rotates around the rotating shaft 11. At the same time, with the cooperation of the rotating rod 37, the driven gear 19 and the driving gear 22, the cleaning brush 14 rotates. Then the cleaning brush 14 can clean the impurities adhering to the inner wall of the valve body 32.

[0034] In this embodiment, the cleaning component 101 specifically includes a cross-shaped limiting groove 15, a scraper 23, three L-shaped clamping plates 25, a filter cartridge 24, a limiting plate 26, a mounting base 27, a second tension spring 28, a sliding shaft 29, a cross-shaped limiting block 30, and three clamping grooves 39.

[0035] A cross-shaped limiting groove 15 is formed at one end of the rotating shaft 11. A cross-shaped limiting block 30 is fixedly connected to one end of the sliding shaft 29. The sliding shaft 29 is slidably connected to the inside of the mounting base 27 via a spline. A second tension spring 28 is sleeved on the outer side wall of the sliding shaft 29. Three slots 39 are symmetrically formed on the inner side wall of the valve body 32. The outer side wall of the filter cartridge 24 is fitted against the inner side wall of the valve body 32. Scrapers 23 are symmetrically fixedly connected to the outer side wall of the mounting base 27. A limiting plate 26 is fixedly connected to the sliding shaft 29 away from the cross-shaped limiting block 30. One end of the second tension spring 28 is fixedly connected to the limiting plate 26, and the other end of the second tension spring 28 is fixedly connected to the mounting base 27. The side of the mounting base 27 away from the second tension spring 28 is rotatably connected to the inner wall of the filter cylinder 24. One side of the scraper 23 is attached to the inner wall of the filter cylinder 24. The sliding shaft 29 is located inside the filter cylinder 24. The sliding shaft 29 is slidably and rotatably connected to the filter cylinder 24. Under the pull of the second tension spring 28, the sliding shaft 29 is connected to the rotating shaft 11, thereby increasing the stability of the structure.

[0036] In this embodiment, specifically, the outer wall of the cross-shaped limiting block 30 is slidably connected to the inner wall of the cross-shaped limiting groove 15, and three L-shaped clamping plates 25 are symmetrically fixedly connected to one side of the filter cartridge 24. The outer wall of the L-shaped clamping plate 25 is attached to the inner wall of the clamping groove 39. The filter cartridge 24 can be conveniently installed through the L-shaped clamping plate 25, and the L-shaped clamping plate 25 can be hidden and installed through the clamping groove 39.

[0037] In this embodiment, specifically, a control component 501 is installed on the outer side wall of the valve body 32. The control component 501 includes two valve seats 33, a sealing ring 34, a handwheel 51, a fixed seat 52, a valve cover 53, a valve stem 54, a ball 55, two support rods 56, a limiting sleeve 57, and a limiting shaft 58.

[0038] The valve stem 54 is mounted on the top of the outer wall of the ball 55, and the limiting shaft 58 is mounted on the top of the outer wall of the ball 55. The ball 55 is located inside the valve body 32 and is rotatably connected to the valve body 32. Two valve seats 33 are symmetrically mounted inside the valve body 32, and the ball 55 is located between the two valve seats 33. The sealing ring 34 is embedded inside the valve seat 33, and the outer wall of the ball 55 is in contact with the outer wall of the sealing ring 34. The valve cover 53 is fixedly connected to the top of the outer wall of the valve body 32 by bolts, and the ball 55 is rotatably connected to the inside of the valve body 32. The outer wall of the ball 55 is rotatably connected to the inner wall of the limiting sleeve 57, and the limiting shaft 58 is rotatably connected to the inside of the valve body 32. The bottom ends of the two support rods 56 are symmetrically fixed. The valve cover 53 is attached to the upper surface. The fixing seat 52 is fixedly connected to the outer wall of the limiting sleeve 57. The top ends of the two support rods 56 are fixedly connected to the fixing seat 52 by bolts. The handwheel 51 is installed on the top of the valve stem 54. The ball 55 is connected to the valve body 32. The bottom end of the limiting sleeve 57 is fixedly connected to the upper surface of the valve body 32. The valve seat 33 is in contact with the outer wall of the ball 55 through the sealing ring 34. The sealing ring 34 can seal the ball 55. The fixing seat 52 can limit the position of the limiting sleeve 57. The limiting sleeve 57 can limit the position of the valve stem 54, thereby enhancing the strength of the valve stem 54. When the valve stem 54 is subjected to external force, it will not bend.

[0039] Working principle: Connect both ends of the valve body 32 to the pipeline. The ball valve controls the opening and closing of the pipeline. By rotating the valve stem 54 clockwise, the valve stem 54 drives the ball 55 to rotate. The through hole inside the ball 55 connects with the flow channel inside the valve body 32, thus allowing the pipeline to pass. When the valve stem 54 is rotated counterclockwise, the through hole inside the ball 55 forms a 90-degree angle with the flow channel, thus closing the pipeline. The valve seat 33 fits against the outer wall of the ball 55 through the sealing ring 34, which seals the ball 55. The fixed seat 52 limits the position of the limiting sleeve 57, which in turn limits the position of the valve stem 54, thereby enhancing the strength of the valve stem 54. When the valve stem 54 is subjected to external force, it will not bend.

[0040] When the medium flows in the pipeline, the medium drives the vortex fan 17 to rotate, which in turn drives the rotating shaft 11 to rotate. The rotating shaft 11 then drives the limiting rod 12 to rotate, causing the outer wall of the limiting wheel 35 to engage with the groove 36. The groove 36 limits the position of the limiting wheel 35, and the limiting wheel 35 reduces friction. As the vortex fan 17 rotates, the rotational speed of the rotating shaft 11 increases. Under the action of centrifugal force, the three sliding rods 13 move away from the rotating shaft 11. When the sliding rods 13 move, they drive the connecting frame 38, which in turn drives... The cleaning brush 14 rotates because the limiting wheel 35 is in contact with the inner wall of the groove 36. When the limiting wheel 35 rotates, it drives the rotating rod 37 to rotate. When the rotating rod 37 rotates, it drives the driving gear 22. The driving gear 22 drives the driven gear 19 through its teeth. The driven gear 19 drives the cleaning brush 14 to rotate. Thus, the cleaning brush 14 rotates around the rotating shaft 11. At the same time, with the cooperation of the rotating rod 37, the driven gear 19 and the driving gear 22, the cleaning brush 14 rotates on its own axis. Thus, the cleaning brush 14 can clean the impurities adhering to the inner wall of the valve body 32.

[0041] During the flow of the medium, since the filter cartridge 24 is located in the flow channel of the valve body 32, impurity particles in the medium can be filtered through the filter cartridge 24, preventing impurity particles from scouring the valve body 32 and improving the service life of the valve body 32. Since the cross limit block 30 is engaged with the cross limit groove 15, when the rotating shaft 11 rotates, the cross limit block 30 drives the sliding shaft 29 to rotate, the sliding shaft 29 drives the mounting seat 27 to rotate, and the mounting seat 27 drives the scraper 23 to clean the impurity particles filtered by the filter cartridge 24, thereby preventing impurity particles from adhering to the filter cartridge 24 and preventing the filter cartridge 24 from becoming clogged. Under the pull of the second tension spring 28, the sliding shaft 29 and the rotating shaft 11 remain connected, thereby increasing the stability of the structure.
