[0003] In the prior art, a ball valve controls the fluid by rotating the ball to change the relative position between the passage on the ball and the pipeline. For the convenience of operation, especially in occasions with frequent operation, the ball valve needs to be placed in an easily accessible place. In this way, it is necessary to avoid accidental touch when walking back and forth and avoid unnecessary accidents caused by accidental touch. In view of this, we have proposed a V-type regulating ball valve. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a V-type regulating ball valve, which can solve the problem of avoiding accidental opening or closing of the ball valve.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a V-type regulating ball valve, including a V-type ball valve. The upper surface of the V-type ball valve is fixedly connected with a mounting frame. The control rod of the V-type ball valve rotates through the upper surface of the V-type ball valve. The upper end of the control rod of the V-type ball valve is fixedly connected with a mounting disc. The lower surface of the mounting disc is fixedly connected with a protective cylinder. The outer surface of the protective cylinder is movably sleeved with a driving adjustment ring. The upper surface of the driving adjustment ring is fixedly connected with a mounting cylinder. The upper end of the mounting cylinder movably penetrates through the upper surface of the mounting frame. The upper and lower surfaces of the driving adjustment ring are both fixedly connected with engaging protrusions. The lower surface of the mounting disc is also fixedly connected with an engaging protrusion. A locking groove is formed on the outer surface of the control rod of the V-type ball valve. Two locking rollers are arranged on the outer surface of the control rod of the V-type ball valve. The adjacent side surfaces of the two locking rollers are fixedly connected with locking protrusions adapted to the locking groove. The opposite ends of the two locking rollers respectively slide through the left and right side surfaces of the mounting frame. An anti-accidental-touch component is arranged on the mounting frame.

[0006] Preferably, the anti-accidental-touch component includes two mounting plates, which are respectively fixedly connected to the left and right inner walls of the mounting frame. The upper surfaces of the two mounting plates are both fixedly connected with support rods. A movement groove extending out of its lower surface is formed on the upper surface of the locking roller. The upper end of the support rod extends out of the upper surface of the locking roller through the movement groove. The upper surface of the support rod is fixedly connected with a mounting ring. The upper surface of the mounting ring is rotatably connected with an elliptical ring.

[0007] Preferably, a protrusion is fixedly connected to the upper surface of the locking roller. A positioning groove adapted to the protrusion is formed on the outer surface of the elliptical ring. The upper surface of the elliptical ring is also fixedly connected with an engaging protrusion.

[0008] Preferably, reset plates are fixedly connected to opposite ends of the two locking rollers respectively, and springs are fixedly connected to the surfaces of the two reset plates close to each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] For this V-type regulating ball valve, when it is necessary to rotate the control rod of the V-type ball valve, by pressing the mounting cylinder, the driving adjusting ring is synchronously driven to descend by the mounting cylinder. After the driving adjusting ring descends and contacts the anti-misoperation component, at this time, the mounting cylinder is rotated by 90 degrees, and the anti-misoperation component is used to unlock the accidentally touched control rod of the V-type ball valve. Then, the mounting cylinder is lifted upward to drive the driving adjusting ring to rise, so as to drive the mounting disc to rotate by means of the cooperation between the driving adjusting ring and the engaging protrusion. When the mounting disc rotates, the control rod of the V-type ball valve can be driven to rotate.

When it is necessary to rotate the control rod of the V-type ball valve 1, by pressing the installation cylinder 6, the driving adjustment ring 5 is synchronously driven to descend by the installation cylinder 6. After the driving adjustment ring 5 descends, it contacts the anti-misoperation component. At this time, the installation cylinder 6 is rotated by 90 degrees, and the anti-misoperation component is used to unlock the accidental contact with the control rod of the V-type ball valve 1. Then, the installation cylinder 6 is lifted upward to drive the driving adjustment ring 5 to rise, so that the installation disc 3 is driven to rotate by the driving adjustment ring 5 in cooperation with the engaging protrusions 7. When the installation disc 3 rotates, the control rod of the V-type ball valve 1 can be driven to rotate. Through the above structure, during normal use, the control rod of the V-type ball valve 1 will not be accidentally rotated due to the passing of surrounding staff, and at the same time, passers-by can be prevented from operating the V-type ball valve 1 out of curiosity, improving the safety of the V-type ball valve 1 during use.

[0024] Furthermore, the anti-misoperation component includes two mounting plates 10 which are respectively fixedly connected to the left and right inner walls of the mounting frame 2. The upper surfaces of the two mounting plates 10 are both fixedly connected with support rods 11. A movement groove 12 extending out of its lower surface is formed on the upper surface of the locking roller 9. The upper ends of the support rods 11 extend out of the upper surface of the locking roller 9 through the movement groove 12. An installation ring 13 is fixedly connected to the upper surface of the support rod 11. An elliptical ring 14 is rotatably connected to the upper surface of the installation ring 13. A protrusion 15 is fixedly connected to the upper surface of the locking roller 9. A positioning groove 16 adapted to the protrusion 15 is formed on the outer surface of the elliptical ring 14. A clamping protrusion 7 is also fixedly connected to the upper surface of the elliptical ring 14. The opposite ends of the two locking rollers 9 are respectively fixedly connected with a reset plate 17. The adjacent side surfaces of the two reset plates 17 are respectively fixedly connected with a spring 18. The adjacent ends of the two springs 18 are respectively fixedly connected with the left and right side surfaces of the mounting frame 2. A second installation ring 19 is rotatably sleeved on the outer surface of the installation cylinder 6. A displacement plate 20 is fixedly connected to the outer surface of the second installation ring 19. Sliding grooves 23 are respectively formed on the left and right inner walls of the mounting frame 2. A limiting rod 21 is fixedly connected between the upper and lower inner walls of the sliding groove 23. The displacement plate 20 is slidably sleeved on the outer surface of the limiting rod 21. Second springs 22 are respectively fixedly connected to the upper and lower side surfaces of the displacement plate 20. The opposite ends of the two second springs 22 are respectively fixedly connected with the upper and lower inner walls of the sliding groove 23. After the driving adjustment ring 5 descends and contacts the elliptical ring 14, at this time, rotating the driving adjustment ring 5 drives the elliptical ring 14 to rotate. After the elliptical ring 14 rotates from the short side to the long side, it presses the protrusion 15. The protrusion 15 synchronously drives the two locking rollers 9 to move away from each other. When the locking rollers 9 move away from each other, the springs 18 will be stretched synchronously, thereby completing the unlocking of the control rod of the V-ball valve 1. And the protrusion 15 is clamped into the positioning groove 16 to avoid self-rotation. Subsequently, the driving adjustment ring 5 can be used to cooperate with the mounting disc 3 for normal operation. After the operation is completed, the driving adjustment ring 5 is used again to drive the elliptical ring 14 to rotate, so that the long side of the elliptical ring 14 becomes the short side. At this time, the two locking rollers 9 are reset by means of the springs 18, completing the locking of the control rod of the V-ball valve 1. When the driving adjustment ring 5 moves up and down, its movement track is restricted by the second installation ring 19, the displacement plate 20 and the limiting rod 21. And the two second springs 22 can ensure that the driving adjustment ring 5 can be in the middle position when not driven by an external force and does not contact the elliptical ring 14 and the mounting disc 3. Through the above structure, it can be made that additional operations are required during unlocking, but all operations are carried out through the installation cylinder 6, reducing the operation complexity while ensuring the normal operation of the anti-misoperation function.

[0025] Working principle: When it is necessary to rotate the control rod of the V-ball valve 1, by pressing the installation cylinder 6, the drive adjustment ring 5 is synchronously driven to descend by the installation cylinder 6. After the drive adjustment ring 5 descends, it contacts the anti-misoperation component. At this time, the installation cylinder 6 is rotated by 90 degrees, and the anti-misoperation component is used to unlock the control rod of the misoperated V-ball valve 1. Then, the installation cylinder 6 is lifted upward to drive the drive adjustment ring 5 to rise, so that the installation disk 3 is driven to rotate by the drive adjustment ring 5 in cooperation with the engaging protrusion 7. When the installation disk 3 rotates, the control rod of the V-ball valve 1 can be driven to rotate. After the drive adjustment ring 5 descends and contacts the elliptical ring 14, at this time, the drive adjustment ring 5 is rotated to drive the elliptical ring 14 to rotate. After the elliptical ring 14 rotates from the short side to the long side, the protrusion 15 is thus squeezed, and the protrusion 15 synchronously drives the two locking rollers 9 to move away from each other. When the locking rollers 9 move away from each other, the spring 18 is synchronously stretched, thereby completing the unlocking of the control rod of the V-ball valve 1, and the protrusion 15 is clamped into the positioning groove 16 to avoid self-rotation. Then, the drive adjustment ring 5 is used in cooperation with the installation disk 3 for normal control. After the control is completed, the drive adjustment ring 5 is used again to drive the elliptical ring 14 to rotate, so that the long side of the elliptical ring 14 is changed to the short side. At this time, the two locking rollers 9 are reset by means of the spring 18 to complete the locking of the control rod of the V-ball valve 1. When the drive adjustment ring 5 moves up and down, its movement track is restricted by the second installation ring 19, the displacement plate 20, and the limiting rod 21, and the two second springs 22 can ensure that the drive adjustment ring 5 can be in the middle position when not driven by an external force and does not contact the elliptical ring 14 and the installation disk 3.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
