Description

Technical Field

[0001] This utility model relates to the field of flange ball valves, specifically a novel flange ball valve. Background Technology

[0002] Ball valves and gate valves belong to the same type of valve. The difference is that the closing element of a ball valve is a ball, which rotates around the valve body's centerline to open and close the valve. Ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of media, while flanged ball valves are made by installing flanges at the inlet or outlet of a regular ball valve, thus facilitating connection to external pipelines.

[0003] In the prior art, in order to facilitate the opening and closing of the ball valve body, the handle is connected to the rotating end of the ball valve body, so that the ball valve body can be opened and closed by rotating the rotating end through the handle.

[0004] However, when the handle is used to rotate the rotating end of the ball valve body, the vibration generated by the ball valve body after long-term use may cause the handle to loosen, which may lead to loosening of the internal closure of the ball valve body and affect the use of the ball valve body. Therefore, this utility model proposes a new type of flange ball valve to solve the above-mentioned technical problems. Utility Model Content

[0007] The traction plate has a placement groove on its end face, a positioning groove on the end face of the placement groove, a guide plate at the bottom of the traction plate, and a moving opening on the side of the guide plate.

[0008] The auxiliary plate has a handle at one end, a metal block on the side, and a limit plate at the other end.

[0009] Preferably, the fixing grooves are provided in multiple sets, and the multiple sets of fixing grooves are arranged in a regular circular pattern about the center of the positioning ring surface, and the positioning ring is fixedly connected to the surface of the ball valve body.

[0010] Preferably, the traction plate is fixedly connected to the surface of the rotating end, and a guide opening is provided on the side of the placement groove, which is connected to the moving opening.

The limiting plate has an overall square plate structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The novel flange ball valve proposed in this utility model allows for the following operation: when the handle is rotated on the rotating end of the ball valve body, the handle can be pulled to disengage the limiting plate from the positioning groove. Then, the auxiliary plate is rotated to move the metal block downwards along the moving port, thereby making the auxiliary plate and the handle perpendicular to the surface of the positioning ring. Finally, the limiting plate can be inserted into the fixing groove to fix the handle, thus preventing the handle from rotating due to vibration. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a novel flange ball valve, comprising: a ball valve body 1, a rotating end 2 on the surface of the ball valve body 1, a positioning ring 3 on the surface of the ball valve body 1, and a fixing groove 4 on the surface of the positioning ring 3; a traction plate 5, a placement groove 16 on the end face of the traction plate 5, a positioning groove 6 on the end face of the placement groove 16, a guide plate 7 at the bottom of the traction plate 5, and a moving opening 8 on the side of the guide plate 7; and an auxiliary plate 9, a handle 10 at one end of the auxiliary plate 9, a metal block 11 on the side of the auxiliary plate 9, and a limit plate 12 at the other end of the auxiliary plate 9.

[0024] When the handle 10 is used to rotate the rotating end 2 of the ball valve body 1, the handle 10 can be pulled to disengage the limiting plate 12 from the positioning groove 6. Then, the auxiliary plate 9 is rotated to move the metal block 11 down along the moving port 8, so that the auxiliary plate 9 and the handle 10 are perpendicular to the surface of the positioning ring 3. Then, the limiting plate 12 can be inserted into the fixing groove 4 to fix the handle 10, thereby preventing the handle 10 from rotating due to vibration.

[0025] Example 2: Based on Example 1, in order to facilitate the rotation of the rotating end 2, a traction plate 5 and a handle 10 are provided inside the ball valve body 1 for opening and closing. The traction plate 5 is fixedly connected to the surface of the rotating end 2. A guide port 13 is opened on the side of the placement groove 16. The guide port 13 is connected to the moving port 8. A first magnet 14 is provided on the end face of the guide port 13. Two sets of first magnets 14 are provided. The two sets of first magnets 14 are symmetrically distributed about the positioning groove 6.

[0026] In use, the metal block 11 is first moved through the guide port 13. Then, the limiting plate 12 set on the end face of the auxiliary plate 9 can be inserted into the positioning groove 6. Then, the metal block 11 is attracted and fixed by the first magnet 14, so as to prevent the limiting plate 12 from directly detaching from the positioning groove 6. Then, the rotating end 2 can be rotated by the cooperation of the handle 10 and the traction plate 5.

[0027] Example 3: Based on Example 2, in order to facilitate the fixing of the rotating traction plate 5, an auxiliary plate 9 is provided. Multiple sets of fixing grooves 4 are provided, and the multiple sets of fixing grooves 4 are arranged in a regular circular pattern about the center of the surface of the positioning ring 3. The positioning ring 3 is fixedly connected to the surface of the ball valve body 1. A second magnet 15 is provided on the end face of the moving port 8. The metal block 11 is slidably connected to the moving port 8 and the guide port 13. The metal block 11 has a square plate structure. The auxiliary plate 9 has a square plate structure. The limiting plate 12 is fixedly connected to the end face of the auxiliary plate 9. The handle 10 is fixedly connected to the end face of the auxiliary plate 9 by positioning bolts. The limiting plate 12 has an overall square plate structure.

[0028] When in use, after rotating the rotating end 2 to a suitable position, the auxiliary plate 9 can be pulled to move the metal block 11 above the moving port 8. The width of the moving port 8 is greater than the width of the metal block 11, so that the metal block 11 can be rotated in the moving port 8. Then, the metal block 11 can be moved along the moving port 8, so that one end of the limiting plate 12 is inserted into the fixing groove 4. The second magnet 15 is used to attract and fix the metal block 11, increasing the stability of the limiting plate 12 inserted into the fixing groove 4. In addition, the auxiliary plate 9 and the handle 10 can be folded for easy storage of the ball valve body 1 later.

[0029] In actual use, the handle 10 can be used to rotate the rotating end 2 of the ball valve body 1, and then the handle 10 can be pulled to disengage the limiting plate 12 from the positioning groove 6. Then, the auxiliary plate 9 can be rotated to move the metal block 11 down along the moving port 8, so that the auxiliary plate 9 and the handle 10 are perpendicular to the surface of the positioning ring 3. Then the limiting plate 12 can be inserted into the fixing groove 4 to fix the handle 10, thereby preventing the handle 10 from rotating due to vibration.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
