[0001] The utility model relates to the technical field of pipeline sealing rings, in particular to a natural gas pipeline sealing ring which is easy to disassemble. Background Art
[0002] A natural gas pipeline is a pipeline that transports natural gas from the mining site to the user. When laying a natural gas pipeline, a sealing ring needs to be installed at the connection between the two pipes to ensure the sealing of the connection.
[0003] At present, the existing sealing ring (such as patent publication number: CN220102276U) discloses a sealing ring and a pipe assembly, which realizes the deflection of the two pipes at any angle by arranging a first sealing part and a second sealing part on a ring surface on one side of the connecting part, and an angle is formed between the first sealing part and the second sealing part. When the deflection amount is large, the angle between the first sealing part and the second sealing part is changed, which can ensure good sealing at the joint of the two pipes and at the same time play a buffering role.
[0004] However, during the implementation of the above technical solutions, it was found that at least the following technical problems exist: the sealing rings are mostly single-layer designs, and the inner side of the sealing rings are easily worn after long-term use, resulting in air leakage. During maintenance, since the leakage point is inside, it cannot be discovered and replaced in time. Utility Model Content

During maintenance, since the leakage point is inside, it cannot be discovered and replaced in time.
[0007] (2) Technical solution
[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0009] A natural gas pipeline sealing ring that is easy to disassemble includes a pipeline body, a first sealing plate is provided on the surface of the pipeline body, a second sealing plate is provided on the surface of the pipeline body, two first rubber strips are fixedly installed inside the first sealing plate, two second rubber strips are fixedly installed inside the first sealing plate, two sleeves are fixedly installed on the top end of the first sealing plate, and a conical push plate is slidably installed inside each sleeve.

[0020] The embodiment of the present application provides a natural gas pipeline sealing ring that is easy to disassemble, which effectively solves the problem that most sealing rings are of single-layer design and the inner side of the sealing ring is easily worn after long-term use, resulting in air leakage. During maintenance, since the leakage point is inside, it cannot be discovered and replaced in time. By rotating the two bolts, the bolts are rotated inside the first fixing plate, and at the same time the bolts rotate into the inside of the second fixing plate, the first fixing plate and the second fixing plate are squeezed and fixed, and the pipeline body and the first sealing plate are fixed and installed at the same time, and the pipeline is sealed by the first rubber strip. At the same time, two second rubber strips are installed on the inner side of the pipeline body, and a certain gap is left between the first rubber strip and the second rubber strip. Through the cooperation of the first rubber strip and the second rubber strip, when the connection end leaks, the gap between the first rubber strip and the second rubber strip intercepts the leaked gas, and the gas is concentrated inside the pipeline body and the first sealing plate. The double protection prevents leakage.
[0021] Example
[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the sealing ring is mostly designed as a single layer. After long-term use, the inner side of the sealing ring is easily worn, resulting in air leakage. During maintenance, since the leakage point is inside, it is difficult to find and replace it in time. The overall idea is as follows:
[0023] In response to the problems existing in the prior art, the utility model provides a natural gas pipeline sealing ring that is easy to disassemble, including a pipeline body 11, a first sealing plate 12 is provided on the surface of the pipeline body 11, a second sealing plate 13 is provided on the surface of the pipeline body 11, two first rubber strips 19 are fixedly installed inside the first sealing plate 12, and two second rubber strips 21 are fixedly installed inside the first sealing plate 12. The pipeline body 11 and the first sealing plate 12 are fixedly installed at the same time, and the pipeline is sealed by the first rubber strip 19. At the same time, two second rubber strips 21 are installed on the inner side of the pipeline body 11, leaving a certain gap between the first rubber strip 19 and the second rubber strip 21. The first rubber strip 19 and the second rubber strip 21 have the same size. Through the cooperation of the first rubber strip 19 and the second rubber strip 21, when the connection end leaks, the gap between the first rubber strip 19 and the second rubber strip 21 intercepts the leaked gas, and the gas is concentrated inside the pipeline body 11 and the first sealing plate 12. Two sleeves 22 are fixedly installed on the top of the first sealing plate 12, and a conical push plate 26 is slidably installed inside each sleeve 22.
[0024] A fixing ring 24 is fixedly installed inside each sleeve 22, a compression rod 25 is fixedly installed at the bottom end of each fixing ring 24, a sliding sleeve 23 is fixedly installed at the top end of each sleeve 22, a docking groove 17 is opened at the bottom end of the first sealing plate 12, two sealing blocks 18 are fixedly installed at the top end of the second sealing plate 13, and the first fixing plate 14 is fixedly installed at both side ends of the first sealing plate 12. The conical push plate 26 moves upward, and a metal sheet is installed at the top end of the conical push plate 26 to push the sliding sleeve 23 to slide on the top end of the sleeve 22. The conical push plate 26 moves inside the sleeve 22. When air deflation occurs, the top of the conical push plate 26 applies a thrust to the sliding sleeve 23 through the movement of the conical push plate 26, so that the sliding sleeve 23 is stretched at the top of the sleeve 22. The expansion of the sliding sleeve 23 serves as a reminder. During inspection and maintenance, the first sealing plate 12 and the second sealing plate 13 can be replaced as a whole in time. Two bolts 16 are rotatably installed inside each first fixing plate 14, and second fixing plates 15 are fixedly installed on both side ends of the second sealing plate 13.
[0025] Working principle:
[0026] The first step is to use the first sealing plate 12 and the second sealing plate 13 by moving them. A docking groove 17 is provided at the bottom end of the first sealing plate 12. At the same time, two sealing blocks 18 are installed on the top end of the second sealing plate 13. By moving the first sealing plate 12 and the second sealing plate 13, the first sealing plate 12 and the second sealing plate 13 are docked. The first sealing plate 12 and the second sealing plate 13 are assembled and installed. The first sealing plate 12 and the second sealing plate 13 respectively drive the first rubber strip 19 to fit with the pipe body 11. By pushing the pipe body 11 and the first sealing plate 12, they can slide on the surface of the pipe body 11, align the two first rubber strips 19 with the connecting ends of the pipe, and rotate the two bolts 16 to make the bolts 1 6 rotates inside the first fixing plate 14, and at the same time, the bolt 16 rotates into the inside of the second fixing plate 15, squeezing and fixing the first fixing plate 14 and the second fixing plate 15, and fixing the pipe body 11 and the first sealing plate 12 at the same time. The pipe is sealed by the first rubber strip 19. At the same time, two second rubber strips 21 are installed on the inner side of the pipe body 11, leaving a certain gap between the first rubber strip 19 and the second rubber strip 21. Due to the cooperation between the first rubber strip 19 and the second rubber strip 21, when the connection end leaks, the gap between the first rubber strip 19 and the second rubber strip 21 intercepts the leaked gas, and the gas is concentrated inside the pipe body 11 and the first sealing plate 12. The double protection prevents the occurrence of leakage.
[0027] In the second step, two conical push plates 26 are installed inside the pipe body 11, and the inside of the sleeve 22 is connected to the inside of the pipe body 11. When natural gas leaks, the natural gas enters the inside of the pipe body 11 and pushes the end of the conical push plate 26. The conical push plate 26 slides inside the sleeve 22, allowing the conical push plate 26 to move upward. At the same time, the conical push plate 26 squeezes the end of the compression rod 25, forcing the compression rod 25 to be compressed inside the sleeve 22. The conical push plate 26 moves upward, and the conical A metal sheet is installed on the top of the push plate 26, which pushes the sliding sleeve 23 to slide on the top of the sleeve 22. The conical push plate 26 moves inside the sleeve 22. When gas leakage occurs, the top of the conical push plate 26 applies a thrust to the sliding sleeve 23 through the movement of the conical push plate 26, so that the sliding sleeve 23 is stretched on the top of the sleeve 22. The expansion of the sliding sleeve 23 serves as a reminder. During inspection and maintenance, the first sealing plate 12 and the second sealing plate 13 can be replaced as a whole in time to prevent leakage of natural gas.
[0028] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
