[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a technical solution: a high-strength leak-proof connection structure for a butterfly valve, including a butterfly valve body 1, connecting pipes 2 on both sides of the butterfly valve body 1, and a connecting assembly between the butterfly valve body 1 and the connecting pipes 2. The connecting assembly includes a first fixing ring 3 fixedly sleeved on the surface of the butterfly valve body 1, a movable ring 4 on one side of the first fixing ring 3, an L-shaped connecting block 5 on one side of the movable ring 4, a through groove 7 on the side of the first fixing ring 3, a connecting rod 8 slidably connected inside the through groove 7, the end of the connecting rod 8 being fixedly connected to the side of the movable ring 4, and a bending spring 9 being provided between the connecting rod 8 and the through groove 7. A second fixing ring 10 is fixedly sleeved on the surface of the connecting pipe 2. The second fixing ring 10 has an L-shaped connecting groove 6 on its side that matches the L-shaped connecting block 5. A limit post 12 is provided on the side of the connecting pipe 2 near the butterfly valve body 1. A limit hole 11 is provided on the side of the butterfly valve body 1 near the connecting pipe 2 that matches the limit post 12. The first fixing ring 3, the movable ring 4, the L-shaped connecting block 5, and the second fixing ring 10 are all made of aluminum alloy, making the device more durable and stronger. Sealing rings are provided on the sides of the butterfly valve body 1 and the connecting pipe 2 that are close to each other, ensuring a tight seal after the butterfly valve body 1 and the connecting pipe 2 are connected. Better and more effectively prevents liquid leakage; when it is necessary to connect the butterfly valve body 1 to the connecting pipe 2, the operator first holds the movable ring 4 and then rotates it outward. At this time, the movable ring 4 drives the connecting rod 8 to slide along the inner side of the through groove 7. At this time, the bending spring 9 is forced open, and the movable ring 4 simultaneously drives the L-shaped connecting block 5 to move. When the movable ring 4 reaches the appropriate position, the operator places the butterfly valve body 1 on one side of the connecting pipe 2, so that the limiting post 12 is inserted into the inner side of the limiting hole 11, and at the same time, the L-shaped connecting block 5 is also inserted into the inner side of the L-shaped connecting groove 6. Then the operator releases the movable ring 4. At this time, the bending spring 9 is no longer forced and contracts, so that the movable ring 1... The moving ring 4 returns to its original position, and the movable ring 4 drives the L-shaped connecting block 5 to move simultaneously, so that the L-shaped connecting block 5 is engaged inside the L-shaped connecting groove 6, completing the connection between the butterfly valve body 1 and the connecting pipe 2. Existing butterfly valves are connected via flanges during installation, requiring multiple tightening of screws, which is cumbersome and reduces installation efficiency. By designing the butterfly valve body 1, connecting pipe 2, and connecting components, personnel can quickly connect the butterfly valve body 1 and connecting pipe 2, effectively improving installation efficiency. The overall structure is compact and easy to operate, bringing convenience to personnel during installation.
[0018] In this embodiment, preferably, please refer to... Figure 1 , Figure 2As shown, it also includes a reinforcing component, which includes a first n-shaped block 13 fixedly installed at the bottom of the first fixing ring 3. A rotating rod 14 is rotatably connected to the inner side of the first n-shaped block 13. A threaded rod 15 is fixedly connected to the surface of the rotating rod 14. A fastening nut 16 is threadedly fitted onto the surface of the threaded rod 15. A third fixing ring 18 is also fixedly fitted onto the surface of the connecting pipe 2. A second n-shaped block 17 is fixedly connected to the bottom of the third fixing ring 18. The first n-shaped block 13 and the second n-shaped block 17 are on the same horizontal axis, so that the threaded rod... When subjected to force, 15 can be effectively engaged inside the second n-shaped block 17. By designing a reinforcing component, after the butterfly valve body 1 and the connecting pipe 2 are connected, the operator can rotate the bottom end of the threaded rod 15 around the rotating rod 14, so that the threaded rod 15 is inside the second n-shaped block 17. Then, the operator can rotate the fastening nut 16, so that the side of the fastening nut 16 abuts against the side of the second n-shaped block 17, and fix the butterfly valve body 1 and the connecting pipe 2 again, so that the connection between the butterfly valve body 1 and the connecting pipe 2 is more secure.
