[0002] Ball valves with wear-resistant and corrosion-resistant nano-coatings have wide application values in industrial and civil fields.

This technology tightens and unscrews an annular nut from a connecting part by tightening the annular nut on the connecting part. Among them, the annular nut wrench tool is accommodated in the control handle in the idle position and can move from the idle position to the working position located outside the control handle. And in the working position, the annular nut wrench tool can be combined with the annular nut. However, this patent has the following defects.

[0015] Technical effects and advantages of the present invention: 1. The present invention adopts a linkage positioning component. After the controller sets the positioning position and number of times, the hand holds and rotates the socket handle. Since the inner wall of the valve housing and the outer wall of the valve ball core are made of nano - coating material, they have better wear and corrosion resistance. During rotation, the socket handle drives the pointed groove to act on the pointed block in turn. When the pointed groove aligns with the second pointed block, under the resilience of the elastic piece, the top of the second pointed block contacts the distance sensor, and at the same time, the electromagnet is triggered to magnetically lock, realizing multi - point precise positioning of the top tip and two inclined surfaces of the second pointed block. This technology enables the socket handle to perform multi - point precise positioning with a single manual rotation, with simple operation, improved efficiency, and greatly improved the manual adjustment accuracy of the nano - coating ball valve.

[0016] 2. Through the linkage positioning component of the present invention, when the second pointed block rotates and positions, multi - point precise positioning is performed on the top tip and two inclined surfaces of the second pointed block. This process also avoids the situation where the socket handle rotates excessively or fails to reach the specified position and needs to be adjusted back and forth multiple times, reducing the wear caused by frequently adjusting the position of the valve ball core, significantly reducing the number of wear times of the valve ball core in the valve housing, and remarkably improving the durability of the valve ball core inside the valve housing.

[0017] 3. The present invention adopts an inclined - side positioning component, and at the same time uses the magnetic attraction of the electromagnet to make the magnetic attraction block tilt upward, thereby making the horizontal and vertical inclined insertion blocks tilt upward and insert into the positioning inclined groove, performing horizontal and vertical inclined linkage positioning on the side of the second pointed block, firmly fixing the second pointed block in the pointed groove, preventing the socket handle from driving the rotating shaft to continue rotating, ensuring that the rotating shaft and the valve ball core are accurately rotated to the specified position, preventing the valve ball core from rotating excessively or not reaching the position, and being able to achieve multi - point precise positioning through the inclined side after a single manual rotation of the socket handle, making the operation simpler, more efficient, and greatly improving the manual adjustment accuracy of the nano - coating valve ball.

[0018] In summary, through the mutual influence of the above - mentioned multiple functions, first, the pointed groove aligns with the second pointed block, making the top of the second pointed block contact the distance sensor, triggering the electromagnet to magnetically lock. At the same time, using the magnetic attraction of the electromagnet to make the magnetic attraction block tilt upward, performing horizontal and vertical inclined linkage positioning on the side of the second pointed block. In summary, this technology enables the socket handle to perform multi - point precise positioning with a single manual rotation, with simple operation, improved efficiency, and greatly improved the manual adjustment accuracy of the nano - coating ball valve.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] As attached Figure 1 - Attachment Figure 8A ball valve with a wear-resistant and corrosion-resistant nano-coating is shown. A linkage positioning component and an inclined-side positioning component are provided on the ball valve with the wear-resistant and corrosion-resistant nano-coating. The setting of each component realizes the multi-point precise positioning of the top tip and two inclined surfaces of the second pointed block 6. This technology enables multi-point precise positioning with a single manual rotation of the socket handle, which is simple to operate, improves efficiency, and greatly enhances the manual adjustment accuracy of the nano-coated ball valve. The specific structural settings of each component are as follows.

[0030] In this embodiment, as Figure 1 - Figure 4 shown, a socket handle 2 is rotatably installed above the valve housing 1. A linkage positioning component is provided at the bottom end of the socket handle 2. The linkage positioning component includes: a pointed groove 5 opened at the bottom end of the socket handle 2. An electromagnet 3 is provided at the top end of the inner wall of the pointed groove 5. A distance sensor 4 is provided on one side of the electromagnet 3. Both the electromagnet 3 and the distance sensor 4 are fixedly connected to the socket handle 2; a plurality of pointed blocks 6 are all located below the socket handle 2. A guide post 7 is fixedly connected to the bottom end of each pointed block 6. Elastic sheets 8 are provided on both sides of the guide post 7. The top end of the elastic sheet 8 is fixedly connected to the pointed block 6. The outer wall of the guide post 7 is slidably connected with an arc-shaped strip 10. A limiting block 9 is fixedly connected to the bottom end of the guide post 7; a convex strip 11 is fixed on the outer wall of the guide post 7. The convex strip 11 is slidably connected with the arc-shaped strip 10. A controller 12 is installed on the upper surface of the socket handle 2. An inclined-side positioning component is provided on the lower surface of the electromagnet 3 for inclined-side positioning of the side surface of the pointed block 6. The plurality of pointed blocks 6 are arranged in an arc and equally spaced distribution. One of the pointed blocks 6 is slidably connected with the socket handle 2; both the electromagnet 3 and the distance sensor 4 are electrically connected to the controller 12, so that the socket handle 2 drives the pointed groove 5 to rotate. After the pointed groove 5 and the first pointed block 6 are squeezed and moved down to complete the separation operation, then the socket handle 2 continues to rotate and squeeze the second pointed block 6. The second pointed block 6 is squeezed and drives the guide post 7 to move down. The second pointed block 6 drives the top ends of the two elastic sheets 8 to move downward. The bottom ends of the elastic sheets 8 are squeezed on the arc-shaped strip 10 to generate deformation. The guide post 7 drives the limiting block 9 to move downward. When the pointed groove 5 at the bottom of the socket handle 2 is aligned with the second pointed block 6, then the two elastic sheets 8 squeeze the second pointed block 6 to move upward. When the distance sensor 4 senses that the distance between the pointed block 6 and the distance sensor 4 is zero, it can be sensed once, and immediately the controller 12 turns on the electromagnet 3 to magnetically lock the top end of the second pointed block 6, which can precisely position and lock the two inclined surfaces and the top tip position of the second pointed block 6.

[0031] In this embodiment, as Figure 2As shown, the bottom end of the elastic piece 8 is fixedly connected to the arc-shaped sleeve strip 10. The two elastic pieces 8 are symmetrically arranged with respect to the guide post 7, and the arc-shaped sleeve strip 10 is fixedly connected to the valve housing 1. The inner wall of the valve housing 1 is sprayed with a nano-coating, so that the second pointed block 6 drives the top ends of the two elastic pieces 8 to move downward. The bottom end of the elastic piece 8 is extruded on the arc-shaped sleeve strip 10 to generate deformation, and at the same time, the guide post 7 can be positioned and guided along the inner wall of the arc-shaped sleeve strip 10 to ensure that the guide post 7 moves vertically according to the specified position. Moreover, the inner wall of the valve housing 1 is a nano-coating, so that the valve housing 1 is more wear-resistant and corrosion-resistant when contacting the valve ball core 24.

[0032] In this embodiment, as Figure 5 - Figure 6 As shown, the inclined-side positioning assembly includes: an inclined sleeve strip 13 fixedly installed on the lower surface of the electromagnet 3. The inner wall of the inclined sleeve strip 13 is connected with a socket block 14, and the top end of the socket block 14 is fixedly connected with a magnetic attraction block 15. The upper surface of the magnetic attraction block 15 is provided with an inclined surface 16; a horizontal and inclined insertion block 17 fixedly connected to the bottom end of the socket block 14. The upper inclined surface of the horizontal and inclined insertion block 17 is fixedly connected with a vertical and inclined insertion block 18. A positioning inclined groove 19 is provided on one side of each pointed block 6, and the positioning inclined groove 19 is used for synchronously inclining and positioning the vertical and inclined insertion block 18 and the horizontal and inclined insertion block 17. The inclined sleeve strip 13 is slidably connected with the socket block 14. The outer wall of the inclined sleeve strip 13 and the inner wall of the socket block 14 are both smooth surfaces. The top end of the vertical and inclined insertion block 18 is processed with a rounded corner, and the top end of the horizontal and inclined insertion block 17 is processed with a rounded corner; an inclined column 20 is slidably connected to the inner wall of the socket block 14, and both ends of the inclined column 20 are fixedly connected to the same inclined sleeve strip 13. So as to utilize the magnetic attraction force of the electromagnet 3 to generate an upward moving force on the magnetic attraction block 15. The magnetic attraction block 15 drives the socket block 14 to incline and move upward. The socket block 14 inclines and moves upward along the inner wall of the inclined sleeve strip 13. At the same time, the socket block 14 inclines and moves upward along the outer wall of the inclined column 20. The vertical and inclined insertion block 18 and the horizontal and inclined insertion block 17 both incline and move upward and are inserted into the positioning inclined groove 19, which can perform horizontal and vertical inclined linkage positioning on the side surface of the second pointed block 6, and firmly position the second pointed block 6 in the inner wall of the pointed groove 5.

[0033] In this embodiment, as Figure 5 As shown, one side of the magnetic attraction block 15 is fixedly connected with an elastic rope 21, and the elastic rope 21 is fixedly connected to the inclined sleeve strip 13. So that when the magnetic attraction block 15 inclines and moves upward, the magnetic attraction block 15 will pull the top end of the elastic rope 21, and the inclined sleeve strip 13 supports the bottom end of the elastic rope 21. In this way, the elastic rope 21 can provide a magnetic attraction pulling force for the magnetic attraction block 15. When the electromagnet 3 is turned off later, under the action of the return force of the elastic rope 21, the magnetic attraction block 15 inclines and moves downward, and the magnetic attraction block 15 can perform a reset operation.

[0034] In this embodiment, as Figure 7 - Figure 8As shown in the figure, a rotating shaft 22 is fixedly connected to the inner wall of the socket handle 2, and the rotating shaft 22 is rotatably connected to the valve housing 1; a sealing gasket 23 is installed in the gap between the rotating shaft 22 and the valve housing 1, and the sealing gasket 23 is rotatably connected to the rotating shaft 22. The bottom end of the rotating shaft 22 is fixedly connected to a valve ball core 24, and sealing rings 25 are rotatably connected to the outer wall of the valve ball core 24 near both ends thereof. A nano-coating is sprayed on both the inner wall and the outside of the valve ball core 24, and the outer wall of the sealing ring 25 is fixedly connected to the valve housing 1. A cavity is formed inside the valve ball core 24, and the vertical cross-sectional shape of the cavity is circular, so as to facilitate the socket handle 2 to drive the rotating shaft 22 to rotate inside the valve housing 1. The sealing gasket 23 performs rotary sealing on the outer wall edge position of the rotating shaft 22. Under the action of the rotating force of the rotating shaft 22, the valve ball core 24 performs sealed rotation inside the two sealing rings 25. The inner wall of the valve housing 1 and the outer wall of the valve ball core 24 are made of nano-coating material, which is more wear-resistant and corrosion-resistant.

[0035] The working principle of the ball valve with a wear-resistant and corrosion-resistant nano-coating of the present invention is as follows: First, when the present invention is installed and docked, one end inner wall of the valve housing 1 is threadedly installed on the pipeline for conveying liquid, and the other pipeline is threadedly docked on the other end inner wall of the valve housing 1. In this way, the liquid enters the cavity inside the valve ball core 24 through the inside of the valve housing 1, and then is guided and conveyed along the cavity inside the valve ball core 24.

[0036] Second, when the present invention performs tip linkage positioning, set the position of the next positioning and the number of positioning times to one on the controller 12. Then, hold the socket handle 2 by hand, and the socket handle 2 drives the rotating shaft 22 to rotate inside the valve housing 1. The rotating shaft 22 rotates inside the sealing gasket 23. At the same time, the sealing gasket 23 performs rotary sealing on the outer wall edge position of the rotating shaft 22. At the same time, the rotating shaft 22 drives the valve ball core 24 to rotate, and the valve ball core 24 rotates inside the valve housing 1. At the same time, the valve ball core 24 rotates inside the two sealing rings 25. And the inner wall of the valve housing 1 and the outer wall of the valve ball core 24 are made of nano-coating material. Therefore, the valve ball core 24 has better wear resistance and corrosion resistance. At the same time, the socket handle 2 drives the pointed groove 5 to rotate. After the pointed groove 5 and the first pointed block 6 are squeezed and moved downward to complete the separation operation, then the socket handle 2 continues to rotate and squeeze the second pointed block 6. The second pointed block 6 is squeezed and drives the guide post 7 to move downward. The second guide post 7 drives the convex strip 11 to move downward. And the second pointed block 6 drives the top ends of the two elastic pieces 8 to move downward. The bottom end of the elastic piece 8 is squeezed on the arc-shaped strip 10 to generate deformation. And the guide post 7 drives the convex strip 11 to move downward along the outer wall of the arc-shaped strip 10. And the guide post 7 drives the limit block 9 to move downward.

[0037] When the pointed groove 5 at the bottom of the socket handle 2 is aligned with the second pointed block 6, under the resilience of the two elastic pieces 8, the elastic pieces 8 squeeze the second pointed block 6 to move upward. The top end of the second pointed block 6 squeezes and contacts the sensing end of the distance sensor 4. When the distance sensor 4 senses that the distance between the second pointed block 6 and the distance sensor 4 is zero, it senses once. Immediately, the electromagnet 3 is turned on through the controller 12. The electromagnet 3 can magnetically lock the top end of the second pointed block 6. In this way, the top tip of the second pointed block 6 is firmly positioned with the inner wall top end of the pointed groove 5 in the socket handle 2. At the same time, the two inclined surfaces of the second pointed block 6 are firmly positioned with the two inclined surfaces of the inner wall of the pointed groove 5 respectively.

[0038] At the same time, when the present invention performs two-way oblique-side linkage positioning, the magnetic suction force of the electromagnet 3 is used to generate an upward force on the magnetic suction block 15. In this way, the magnetic suction block 15 obliquely moves upward under the action of the magnetic suction force. The magnetic suction block 15 drives the socket block 14 to obliquely move upward. The socket block 14 obliquely moves upward along the outer wall of the inclined column 20 and obliquely moves upward along the inner wall of the inclined sleeve bar 13. The socket block 14 drives the horizontal oblique insertion block 17 to obliquely move upward. The horizontal oblique insertion block 17 drives the vertical oblique insertion block 18 to obliquely move upward. Both the vertical oblique insertion block 18 and the horizontal oblique insertion block 17 obliquely move upward and are inserted into the positioning oblique groove 19. Thus, the horizontal oblique insertion block 17 and the vertical oblique insertion block 18 perform horizontal and vertical inclined linkage positioning on the side surface of the second pointed block 6, and the second pointed block 6 can be firmly fixed in the pointed groove 5 inside the socket handle 2 according to the positioning position. In this way, it is avoided that the socket handle 2 drives the rotating shaft 22 to continue rotating, ensuring that the rotating shaft 22 can be manually rotated to the specified position, and the rotating shaft 22 can drive the valve ball core 24 to rotate to the specified position, avoiding excessive rotation of the valve ball core 24 or the valve ball core 24 not rotating to the specified position. It can be realized that after the socket handle 2 is manually rotated to the specified position at one time, multi-point precise positioning of the top tip double sides and inclined sides of the second pointed block 6 is performed until it is positioned to the specified position. This not only makes the operation simple and more efficient, but also greatly improves the accuracy of the nano-coated valve ball during manual adjustment.
