Description

Technical Field

[0001] This utility model relates to the field of gas pipeline installation technology, and more specifically to a gas pipeline through-wall sealing device. Background Technology

[0002] Gas pipeline wall penetration sealing devices are an important component of gas transmission and distribution systems, and their design rationality and reliability directly affect the long-term safe operation of gas pipelines. With the increasing penetration rate of urban gas and the expansion of pipeline laying areas, it is necessary to ensure the performance of wall penetration sealing devices.

[0003] As shown in the prior art disclosed in CN222911002U, although this prior art, through an outer sleeve with a through-hole structure and a rubber inner liner, can maintain a sealed and fixed connection with the wall after the sealing material is filled, the gas pipe installed inside the rubber inner liner does not directly contact the sealing material, thus avoiding the problem of direct adhesion to the sealing material; the end cap units at both ends are easy to install and remove, maintaining the sealing function; overall, the device is easy to install and remove, avoiding the problem of gas pipe adhesion hindering disassembly, and facilitating maintenance and disassembly operations. However, this prior art cannot promptly assess the performance of the gas pipe encased in the wall, meaning that workers cannot promptly detect gas leaks, posing a certain safety hazard and affecting the practicality of the prior art. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a gas pipeline through-wall sealing device. Through the connection between the vent and the gas chamber, leaked gas can enter the gas chamber through the vent and then enter the warning gas bag through the gas pipe. The warning gas bag expands to form a visible warning sign, thereby alerting the gas pipeline inside the wall to a leak. This enables rapid investigation and timely notification for maintenance, thereby reducing safety hazards and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas pipeline through-wall sealing device, including an inner tube, an air cavity is opened inside the inner tube, and a plurality of air holes are opened on the inner side wall of the inner tube in a ring array, the air holes being connected to the air cavity; Both ends of the inner tube are equipped with air tubes, and the air tubes are connected to the air chamber. The end of the air tube away from the inner tube is fixedly connected to a warning airbag.

[0006] In a preferred embodiment, both ends of the inner tube are fitted with outer tubes, and both outer tubes can have multiple fixing holes arranged in a ring array on their outer surfaces; A connecting ring is provided between the two outer pipes. The connecting ring is fixed to one of the outer pipes, and a connecting groove is opened on the side of the other outer pipe near the connecting ring. The connecting ring is located inside the connecting groove and is threadedly connected to the connecting groove. The outer pipe shields and protects the outside of the inner pipe, thereby preventing the grouting material from directly adhering to the outside of the gas pipeline. The threaded connection between the connecting ring and the connecting groove facilitates the assembly and connection of the two outer pipes.

[0007] In a preferred embodiment, each of the two outer tubes has an assembly ring on its far side, and a connecting ring is installed on the side of the assembly ring closest to the outer tube. The connecting ring is sleeved on the outside of the outer tube, and a plurality of fastening bolts arranged in a ring array are provided on the outside of the connecting ring. The fastening bolts pass through the connecting ring and extend into the inside of the outer tube. The fastening bolts are threaded to the outer tube, and the outer tube is connected to the assembly ring by the fastening bolts. Then, the assembly ring is connected to the wall to ensure the stability of the inner and outer tubes.

[0008] In a preferred embodiment, the assembly ring has multiple assembly holes on its outer side, which are arranged in a ring array. A grouting pipe is fixedly connected to the bottom end of the assembly ring away from the connecting ring. The assembly holes facilitate the operation of the fastening equipment by the workers to connect it to the wall, and then grouting is performed through the grouting pipe, thereby enhancing the stability of the outer and inner pipes within the wall.

[0009] In a preferred embodiment, the inner diameter of the assembly ring is smaller than the outer diameter of the inner tube, and the inner diameter of the inner tube is smaller than the inner diameter of the assembly ring. By setting the inner diameter of the assembly ring to be larger than the diameter of the inner tube, and the inner diameter of the inner tube to be smaller than the inner diameter of the assembly ring, the assembly ring can limit the inner tube and the outer tube, preventing the inner tube and the outer tube from separating from the assembly ring, thereby ensuring the stability of the overall structure.

[0010] In a preferred embodiment, a sealing ring is installed on the side of the inner tube near the assembly ring. The sealing ring is located inside the assembly ring and is sleeved on the outside of the air tube. By setting the sealing ring, the inner tube can be shielded to prevent external impurities from adhering to the outside of the inner tube and causing damage.

[0011] The technical effects and advantages of this utility model are as follows: By connecting the vent and the gas chamber, leaking gas can enter the gas chamber through the vent and then enter the warning gas bag through the gas pipe. The warning gas bag expands to form a visible warning sign, which can alert the gas pipeline inside the wall to the discovery of a leak, achieving the effect of rapid investigation and timely notification for maintenance, thereby reducing safety hazards.

[0014] 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.

[0015] Refer to the instruction manual appendix Figure 1-5 This utility model provides a gas pipeline through-wall sealing device, including an inner tube 1, an air cavity 2 is opened inside the inner tube 1, and a plurality of air holes 3 are opened on the inner side wall of the inner tube 1 in a ring array, the air holes 3 are connected to the air cavity 2; gas pipes 4 are installed at both ends of the inner tube 1, and the gas pipes 4 are connected to the air cavity 2, and a warning airbag 5 is fixedly connected to the end of the gas pipe 4 away from the inner tube 1.

[0016] When using the aforementioned equipment to enclose four gas pipes through a wall, the worker first installs the inner pipe 1 onto the outside of the four gas pipes. To ensure the stability and strength of the inner pipe 1, it is necessary to limit its movement. Therefore, outer tubes 6 are fitted around both ends of the inner tube 1. Multiple fixing holes 7 arranged in a ring array are formed on the exterior of each outer tube 6. A connecting ring 8 is provided between the two outer tubes 6. The connecting ring 8 is fixed to one of the outer tubes 6, and a connecting groove 9 is formed on the side of the other outer tube 6 near the connecting ring 8. The connecting ring 8 is located inside the connecting groove 9 and is threadedly connected to the connecting groove 9. This allows the two outer tubes 6 to be fitted around the inner tube 1, and the threaded connection between the connecting ring 8 and the connecting groove 9 facilitates the connection of the two outer tubes 6 into a single unit, thus ensuring the stability of the two outer tubes 6.

[0017] Furthermore, to facilitate the fixing of the inner tube 1 and outer tube 6 to the interior of the wall, the outer tube 6 is connected to the assembly ring 10 using fastening bolts 12, thereby ensuring a tight connection between the assembly ring 10 and the inner and outer tubes 1 and 6. The assembly ring 10 has multiple assembly holes 13 arranged in a circular array on its exterior, and a grouting pipe 14 is fixedly connected to the bottom end of the assembly ring 10 away from the connecting ring 11. This allows workers to use external fastening equipment to connect to the wall through the assembly holes 13, achieving the effect of fixing the entire device inside the wall. Then, the grouting material is filled into the wall through the grouting pipe 14, and the grouting material will fill the fixing hole 7 on the outer pipe 6, thereby enhancing the tightness of the connection between the outer pipe 6 and the wall and preventing the outer pipe 6 from becoming loose.

[0018] The inner diameter of the assembly ring 10 is smaller than the outer diameter of the inner tube 1, and the inner diameter of the inner tube 1 is smaller than the inner diameter of the assembly ring 10. A sealing ring 15 is installed on the side of the inner tube 1 closest to the assembly ring 10. The sealing ring 15 is located inside the assembly ring 10 and sleeved on the outside of the air tube 4. This allows the assembly ring 10 to limit and fix the inner tube 1 and the outer tube 6, thus preventing the inner tube 1 from separating from the assembly ring 10. The sealing ring 15 fills the gap between the inner tube 1 and the assembly ring 10, thus preventing impurities from entering the inner tube 1 and causing contamination.

[0019] After the inner pipe 1, outer pipe 6, and assembly ring 10 are installed, the connection between the vent 3 and the gas chamber 2 allows the leaking gas from gas pipe 4 to enter the gas chamber 2 through the vent 3, and then through the gas pipe 4 into the warning airbag 5. The warning airbag 5 inflates to form a visible warning sign, thus alerting workers to the presence of a leak in gas pipe 4 within the wall, requiring timely inspection and maintenance. This reduces safety hazards.

[0020] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
