[0032] 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.

[0033] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a quick-connect sealing assembly for oil and gas storage and transportation pipelines, including a pipe body 1 and a pipe body 2. Pipe body 1 and pipe body 2 are used to connect different pipelines. A connecting ring 3 is fixedly connected to the inner wall of pipe body 2. The connecting ring 3 provides space for opening through grooves 4 and simultaneously connects pipe body 1 and pipe body 2 with a connecting block 11. Two through grooves 4 are opened inside the connecting ring 3. When the two pipelines are connected, the through grooves 4 allow the connecting block 11 to enter the interior of pipe body 1 through the through grooves 4. Fixing rings 5 ​​are respectively fitted onto the exterior of pipe body 1 and pipe body 2. The fixing rings 5 ​​are used to fix and protect the two pipelines after connection. The fixed ring 5 has a connecting groove 6 inside, which cooperates with the limiting block 7 to complete the connection between the fixed ring 5 on the outside of the pipe body 1 and the pipe body 2. Two fixing plates 9 are fixedly connected to the rear side of the fixed ring 5, so that the two fixing plates 9 fit together to complete the fixation of the pipe. Two screws 10 are threaded inside the fixing plates 9 to fix the fixing plates 9. Two connecting blocks 11 are fixedly connected to the inner wall of the pipe body 1. When the two pipes are connected, the connecting blocks 11 pass through the through groove 4 and then rotate the pipe body 1, so that the connecting blocks 11 clamp the left side of the connecting ring 3 to complete the connection. The pipe body 2 has a sealing component inside to seal the pipe connection.

[0034] Reference Figure 2 and Figure 4 Another fixed ring 5 is rotatably connected to a limiting block 7 at its top. The limiting block 7 is used to connect with the connecting groove 6 to complete the connection of the two fixed rings 5. The top of the limiting block 7 is fixedly connected to a lever 8, which allows the operator to use the lever 8 to drive the limiting block 7 away from the connecting groove 6, thereby releasing the connection of the two fixed rings 5.

[0035] Reference Figure 3 and Figure 5The sealing assembly includes a connecting groove 12, which provides fixation and support for spring 13 and provides limiting and guiding functions for sealing ring 14. Multiple springs 13 are fixedly connected to the inner left side of the connecting groove 12. Springs 13 have elasticity and provide elastic support for sealing ring 14. Sealing ring 14 is fixedly connected to the right side of multiple springs 13. During connection, sealing ring 14 and sealing ring 18 are squeezed against each other, thereby deforming and fitting into the interior of sealing groove 16, thus completing the seal.

[0036] Reference Figures 1 to 3 A protruding ring 15 is fixedly connected to the left side of the pipe body 1. During connection, the protruding ring 15 is slidably inserted into the interior of the connecting groove 12. The outside of the connecting block 11 is slidably connected to the interior of the through groove 4. The through groove 4 provides a limiting and guiding function for the connecting block 11. The right side of the connecting block 11 is in contact with the left side of the connecting ring 3. The connecting block 11 fits and is snapped into the left side of the connecting ring 3, completing the connection of the two pipes. A sealing groove 16 is opened inside the protruding ring 15. The sealing groove 16 provides a fixing and supporting function for the second spring 17. Multiple second springs 17 are fixedly connected to the inner wall of the right side of the sealing groove 16. The second spring 17 has an elastic function and provides elastic support for its second sealing ring 18. The outside of the limiting block 7 is in contact with the inner wall of the connecting groove 6. The cooperation between the limiting block 7 and the connecting groove 6 completes the connection of the two fixed rings 5.

[0037] Multiple positioning blocks 19 are fixedly connected to the outside of pipe body 1 and pipe body 2 respectively. The positioning blocks 19 cooperate with the positioning grooves 20 to facilitate the installation of the fixing ring 5. Multiple positioning grooves 20 are opened inside the fixing ring 5. Similarly, the positioning blocks 19 cooperate with the positioning grooves 20 to facilitate the installation of the fixing ring 5. The inner wall of the positioning groove 20 is in contact with the outside of the positioning block 19. After use, the limiting block 7 is disengaged from the connecting groove 6, and the fixing ring 5 can be removed. When in use, the fixing ring 5 can be installed and used by cooperating with the positioning grooves 20 and the positioning blocks 19. Multiple springs 2 17 are fixedly connected to the left side of the sealing rings 2 18. The springs 2 17 provide elastic support for the sealing rings 2 18 and cooperate with the sealing ring 1 14 to complete the sealing.

[0038] The external of the protruding ring 15 is slidably connected to the inside of the connecting groove 12. The right side of the sealing ring 14 and the left side of the sealing ring 18 are in contact. When the two pipes are connected, the protruding ring 15 slides into the inside of the connecting groove 12, and the sealing ring 14 and the sealing ring 18 are squeezed against each other. The sealing ring 14 is elastically supported by the spring 13, and the sealing ring 18 is elastically supported by the spring 17, so that the sealing ring 14 and the sealing ring 18 are squeezed against each other, and thus deformed to complete the connection and seal between the two pipes. The external of the connecting groove 12 is opened inside the pipe body 2, and the pipe body 2 provides space for the connecting groove 12.

[0039] Working principle: When connecting two pipes, align the connecting block 11 of pipe body 1 with the through groove 4, insert it, and then rotate pipe body 1. The connecting block 11 then clamps the left side of the connecting ring 3, achieving initial pipe connection. Then, the fixing rings 5 ​​outside pipe body 1 and pipe body 2 are positioned and installed using the positioning block 19 and positioning groove 20. Then, rotate the limiting block 7 to embed it into the connecting groove 6 of the other fixing ring 5. Finally, tighten the screws 10 on the fixing plate 9. With the synergistic effect of the fixing ring 5 and the fixing plate 9, the pipe connection is secured, ensuring a stable connection and preventing pipe loosening.

[0040] When the pipeline connection is sealed, as the protruding ring 15 of pipe body 1 slides into the connecting groove 12 of pipe body 2, the sealing ring 14 and sealing ring 18 are pressed against each other by the protruding ring 15. Multiple springs 13 provide elastic support for sealing ring 14, and multiple springs 27 provide elastic support for sealing ring 18. Under the elastic action, sealing ring 14 and sealing ring 18 are deformed by pressure and tightly fit into the sealing groove 16, sealing the gap at the pipeline connection in all directions, effectively preventing oil and gas leakage, providing reliable sealing protection for the safe operation of oil and gas storage and transportation pipelines, and ensuring the safe and efficient operation of oil and gas storage and transportation.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
