Description

Technical Field

[0001] This utility model belongs to the field of ball control valve technology, and in particular relates to an adjustable ball control 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's axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their V-shaped ball core and hard alloy-faced metal seat, possess strong shearing force, making them particularly suitable for media containing fibers or small solid particles. Multi-port ball valves not only flexibly control the merging, splitting, and switching of flow directions in pipelines, but also allow the closure of any channel while connecting two other channels. These types of valves should generally be installed horizontally in pipelines.

[0003] In the prior art, after the adjustable ball control valve is closed, the regulating switch generally does not have a positioning structure, which makes it easy for the regulating switch to loosen under external influences, affecting the stable use in the later stage. Therefore, an adjustable ball control valve is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable ball control valve to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an adjustable ball control valve, comprising a first valve body and a second valve body. Both ends of the first and second valve bodies are provided with connecting flanges, which are connected to each other. Several connecting bolts are screwed between the two connecting flanges. A connecting seat is welded to the upper surface of the first valve body, and the interior of the connecting seat is connected to the interior of the first valve body. A mounting seat is slidably connected inside the connecting seat. A fixing frame is welded to one end of the upper surface of the connecting seat, and a connecting shaft is installed inside the fixing frame. A rotating plate is rotatably installed on the circumferential side of the connecting shaft.

[0007] Furthermore, threaded holes are provided on both sides of the upper surface of the connecting seat, the interior of the mounting seat is connected to the interior of the connecting seat, and fixing bolts are slidably installed on both sides of the upper surface of the mounting seat.

[0008] Furthermore, the lower ends of both fixing bolts penetrate the upper surface of the mounting base, and the positions of the two fixing bolts correspond to the positions of the two threaded holes.

[0009] Furthermore, the lower ends of the two fixing bolts are screwed and fixed to the threaded holes, and a valve stem is rotatably installed inside the mounting base. The lower end of the valve stem extends into the first valve body through the mounting base and the connecting seat.

[0010] Furthermore, a valve core is welded to one end of the valve stem, the upper end of the valve stem extends to the outside of the mounting base, and a rotating tip is welded to the upper end of the valve stem.

[0011] Furthermore, a positioning frame is welded to one side of the rotating top, and through holes are provided on both opposite surfaces of the positioning frame, with a positioning rod slidably installed between the two through holes.

[0012] Furthermore, one end of the positioning rod passes through the upper end of the rotating plate, and the positioning rod is slidably connected to the rotating plate.

[0013] Furthermore, a connecting sleeve is welded to the other side of the rotating top, and a rotating rod is engaged inside the connecting sleeve.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through its positioning frame, rotating plate, and positioning rod structure, allows the rotating rod to be easily engaged inside the connecting sleeve after the valve has been used. Rotation causes the rotating tip to rotate, which in turn rotates the valve stem, which in turn rotates the valve core to close the valve. At this point, the rotating tip rotates the positioning frame above the fixed frame. The rotating plate is then flipped upwards, with one end rotating on the connecting shaft and the other end rotating to the positioning frame, parallel to the through hole on the positioning frame. This facilitates the insertion and fixation of the positioning rod, ensuring the position of the rotating tip is secure and preventing the valve from loosening due to external forces when closed.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figures 1-4As shown, this utility model is an adjustable ball control valve, including a first valve body 1 and a second valve body 2. Both ends of the first valve body 1 and the second valve body 2 are provided with connecting flanges 3. The connecting flanges 3 on one end of the first valve body 1 and the second valve body 2 are mated together. Several connecting bolts 4 are screwed between the two connecting flanges 3. A connecting seat 5 is welded to the upper surface of the first valve body 1, and the interior of the connecting seat 5 is connected to the interior of the first valve body 1. A mounting seat 7 is slidably connected inside the connecting seat 5. A fixing frame 14 is welded to one end of the upper surface of the connecting seat 5. A connecting shaft 15 is installed inside the fixing frame 14. A rotating plate 16 is rotatably installed on the circumferential side of the connecting shaft 15. Threaded holes 6 are opened on both sides of the upper surface of the connecting seat 5. The interior of the mounting seat 7 is connected to the interior of the connecting seat 5. 7. Fixing bolts 8 are slidably installed on both sides of the upper surface, so that after the valve is used, the rotating rod 12 can be snapped into the connecting sleeve 11 and rotated to make the rotating tip 10 rotate. When the rotating tip 10 rotates, it drives the valve stem 9 to rotate. When the valve stem 9 rotates, it drives the valve core to rotate and close the valve. At this time, the rotating tip 10 drives the positioning frame 13 to rotate above the fixing frame 14. Then, the rotating plate 16 is flipped upward. One end of the rotating plate 16 rotates on the connecting shaft 15, and the other end rotates to the positioning frame 13, parallel to the through hole 17 on the positioning frame 13. This makes it easy to insert and fix the positioning rod 18, and to fix the position of the rotating tip 10 at this time, so as to prevent the valve from loosening due to external force when it is closed.

[0027] The lower ends of the two fixing bolts 8 penetrate the upper surface of the mounting base 7. The positions of the two fixing bolts 8 correspond to the positions of the two threaded holes 6. The lower ends of the two fixing bolts 8 are screwed and fixed to the threaded holes 6. The valve stem 9 is rotatably installed inside the mounting base 7. The lower end of the valve stem 9 extends into the first valve body 1 through the mounting base 7 and the connecting seat 5. Extension ends are provided on both sides of the upper surface of the mounting base 7 to facilitate limiting and installing the fixing bolts 8.

[0028] A valve core is welded to one end of the valve stem 9. The upper end of the valve stem 9 extends to the outside of the mounting base 7. A rotating top end 10 is welded to the upper end of the valve stem 9. A positioning frame 13 is welded to one side of the rotating top end 10. Through holes 17 are opened on both opposite surfaces of the positioning frame 13. A positioning rod 18 is slidably installed between the two through holes 17. The front surface of the positioning frame 13 has an open structure to facilitate the normal rotation of the rotating plate 16. The width of the rotating plate 16 is smaller than the internal width of the positioning frame 13.

[0029] One end of the positioning rod 18 passes through the upper end of the rotating plate 16, and the positioning rod 18 is slidably connected to the rotating plate 16. A connecting sleeve 11 is welded to the other side of the rotating top end 10, and a rotating rod 12 is engaged inside the connecting sleeve 11. One end of the positioning rod 18 passes through a through hole 17 on one side and extends out through the other through hole 17 via the rotating plate 16. (See also...) Figures 1-4As shown, this utility model is an adjustable ball control valve. Its usage is as follows: After the ball valve has been adjusted and used, if it needs to be closed, first, the rotating rod 12 is engaged inside the connecting sleeve 11 and rotated so that the rotating tip 10 rotates. When the rotating tip 10 rotates, it drives the valve stem 9 to rotate, and when the valve stem 9 rotates, it drives the valve core to rotate, closing the valve. At this time, the rotating tip 10 drives the positioning frame 13 to rotate above the fixed frame 14. Then, the rotating plate 16 is flipped upwards. One end of the rotating plate 16 rotates on the connecting shaft 15, and the other end rotates to the positioning frame 13, parallel to the through hole 17 on the positioning frame 13. This facilitates the insertion and fixing of the positioning rod 18, and helps to fix the position of the rotating tip 10 at this time, preventing the valve from loosening due to external forces when closed.
