Description

Technical Field

[0001] This utility model relates to the field of pipeline connection, specifically a gas meter and gas pipeline leak-proof connection device for airport logistics. Background Technology

[0002] In gas transmission systems, pipeline leak prevention devices are key equipment to ensure the safe and stable transmission of gas. Their function is to prevent gas from leaking at pipeline connections through specific structural designs and sealing methods, thereby avoiding safety accidents caused by gas leaks, such as fires and explosions. At the same time, they ensure stable pressure during gas transmission, reduce energy consumption, and maintain the normal operation of the entire gas supply network.

[0003] Currently, the most common method for connecting gas meters and gas pipelines is to use flange connections. This method involves fixing the gas meter and the gas pipeline to their respective flanges, then using bolts to tightly connect the two flanges together, and placing a gasket at the connection gap. The elastic deformation of the gasket fills the gap, thereby achieving a sealing effect.

[0004] However, airport gas pipelines are often exposed to the external environment for extended periods. Prolonged exposure to sunlight can affect the gaskets at the flange connection gaps, causing them to age, harden, and lose elasticity, eventually leading to damage and seriously affecting the safety of gas pipelines in transporting gas. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a gas meter and gas pipeline leak-proof connection device for airport logistics, so as to solve the technical problem that the sealing effect of the gas meter and gas pipeline flange connection is poor when using a sealing gasket.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas meter and gas pipeline leak-proof connection device for airport logistics, comprising a gas pipeline, a first pipe fixed to the outer wall of the gas pipeline, a connecting plate at the end of the first pipe, a connector connected to one side of the connecting plate, a second pipe at one end of the connector, a gas meter installed at the end of the second pipe, inner pipes on both sides of the connector, a sealing pipe connected to the end of the inner pipe, multiple sets of protruding rings on the outer wall of the sealing pipe, and grooves on the inner walls of both the first and second pipes.

[0007] By adopting the above technical solution, the problem of poor sealing effect of the gasket at the flange connection between the gas meter and the gas pipeline is solved. The gas inside the first pipeline squeezes the sealing tube outwards, so that the outer wall of the sealing tube is tightly attached to the inner wall of the first pipeline. The convex ring is embedded in the groove, and the convex ring seals the gap between the sealing tube and the first pipeline. In addition, the sealing ring seals the gap between the inner tube and the first pipeline, thereby achieving a secondary seal for the first pipeline. Furthermore, the sealing ring and the sealing tube are located inside the first pipeline, which can prevent the sealing ring and the sealing tube from aging due to sun exposure.

[0008] The present invention is further configured such that a protective block is provided on the inner wall of the first pipe, the protective block is located at the end of the slot, and the diameter of the protective block is equal to the diameter of the sealing pipe.

[0009] Preferably, when the sealing tube is inserted into the first pipe, the end of the sealing tube is tightly fitted to one side of the protective block. The protective block protects the end of the sealing tube, preventing the impact force of the gas when the first pipe is filled with gas from causing the end of the sealing tube to be lifted up.

[0010] The present invention is further configured such that one end of the inner tube is provided with multiple sets of fixing blocks, and the fixing blocks are installed inside the sealing tube.

[0011] Preferably, the fixing block secures the sealing tube to prevent the inner ring of the sealing tube from warping during installation.

[0012] The present invention is further configured such that both the sealing tube and the convex ring are made of rubber, and the diameter of the convex ring is the same as the diameter of the groove.

[0013] Preferably, when the sealing tube is installed inside the first pipe, the convex ring is embedded in the groove, and the convex ring seals the gap between the sealing tube and the first pipe.

[0014] The present invention is further configured such that a sealing ring is fitted on the outer wall of the inner tube, and the diameter of the sealing ring is equal to the inner wall diameter of the first pipe.

[0015] Preferably, the sealing ring seals the gap between the inner tube and the first pipe, thereby achieving a secondary seal for the first pipe.

[0016] The present invention is further configured such that connecting rings are provided on both sides of the connector, and grooves are provided at the ends of the first pipe and the second pipe.

[0017] Preferably, when the connector is installed into the first pipe, the connecting ring of the connector is embedded in the groove on one side of the first pipe. The setting of the connecting ring increases the connection strength of the connector, so that when the connector is installed inside the first pipe, the inner pipe will not break due to external pressure on the connector, thereby increasing the service life of the connector.

[0018] The present invention is further configured such that the outer wall of the connecting ring is provided with four sets of limiting blocks, and a limiting groove is provided at one end of the first pipe.

[0019] Preferably, personnel can precisely install the connector by inserting the limiting block into the limiting groove, so that the holes on the connector are aligned with the holes on the connecting plate at the end of the first pipe, thereby facilitating the installation of the connector onto the connecting plate using bolts.

[0020] The present invention is further configured such that the first pipe, the second pipe and the connector are connected by bolts.

[0021] Preferably, the first pipe, the second pipe, and the connector are provided with four sets of holes, and the connector is connected to the first pipe and the second pipe by bolts.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of poor sealing effect of the gasket at the flange connection between the gas meter and the gas pipeline by setting up a gas pipeline, a gas meter, a connector, a groove, a convex ring, a sealing tube, and a sealing ring. The gas inside the first pipeline squeezes the sealing tube outwards, so that the outer wall of the sealing tube is tightly attached to the inner wall of the first pipeline. The convex ring is embedded in the groove and seals the gap between the sealing tube and the first pipeline. In addition, the sealing ring seals the gap between the inner tube and the first pipeline, thereby achieving a secondary seal for the first pipeline. Furthermore, the sealing ring and the sealing tube are located inside the first pipeline, which can prevent the sealing ring and the sealing tube from aging due to sun exposure.

[0024] 2. By setting a limiting block, a connecting ring, a groove, and a limiting slot, this utility model ensures that when the connector is installed in the first pipe, the connecting ring of the connector is embedded in the groove on one side of the first pipe. The setting of the connecting ring increases the connection strength of the connector, so that when the connector is installed inside the first pipe, the inner pipe will not break due to external pressure on the connector, thereby increasing the service life of the connector.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Please see Figure 1 — Figure 4 The system includes a gas pipeline 1, a first pipeline 2 fixed to the outer wall of the gas pipeline 1, a connecting plate 203 at the end of the first pipeline 2, a connector 5 connected to one side of the connecting plate 203, a second pipeline 4 at one end of the connector 5, a gas meter 3 installed at the end of the second pipeline 4, inner pipes 501 on both sides of the connector 5, and sealing pipes 504 connected to the ends of the inner pipes 501. The outer wall of the sealing pipe 504 is provided with multiple sets of raised rings 505. The inner walls of both the first pipeline 2 and the second pipeline 4 are provided with grooves 202, which solves the problem of poor sealing effect at the flange connection between the gas meter and the gas pipeline using a sealing gasket. The problem is that the gas inside the first pipe 2 squeezes the sealing tube 504 outwards, causing the outer wall of the sealing tube 504 to fit tightly against the inner wall of the first pipe 2. The convex ring 505 is embedded in the slot 202, and the convex ring 505 seals the gap between the sealing tube 504 and the first pipe 2. In addition, the sealing ring 502 seals the gap between the inner tube 501 and the first pipe 2, thereby achieving a secondary seal for the first pipe 2. Furthermore, the sealing ring 502 and the sealing tube 504 are located inside the first pipe 2, which can prevent the sealing ring 502 and the sealing tube 504 from aging due to sun exposure.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The inner wall of the first pipe 2 is provided with a protective block 201. The protective block 201 is located at the end of the slot 202, and the diameter of the protective block 201 is equal to the diameter of the sealing tube 504. When the sealing tube 504 is inserted into the first pipe 2, the end of the sealing tube 504 is tightly attached to one side of the protective block 201. The protective block 201 protects the end of the sealing tube 504 and prevents the impact force of the gas when the first pipe 2 is filled with gas from impacting and lifting the end of the sealing tube 504.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 Multiple sets of fixing blocks 503 are provided at one end of the inner tube 501, and the fixing blocks 503 are installed inside the sealing tube 504. The fixing blocks 503 fix the sealing tube 504 to prevent the inner ring of the sealing tube 504 from warping during the installation process.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 Both the sealing tube 504 and the convex ring 505 are made of rubber. The diameter of the convex ring 505 is the same as the diameter of the groove 202. When the sealing tube 504 is installed inside the first pipe 2, the convex ring 505 is embedded in the groove 202, and the convex ring 505 seals the gap between the sealing tube 504 and the first pipe 2.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The outer wall of the inner tube 501 is fitted with a sealing ring 502, and the diameter of the sealing ring 502 is equal to the inner wall diameter of the first pipe 2. The sealing ring 502 seals the gap between the inner tube 501 and the first pipe 2, thereby achieving a secondary seal of the first pipe 2 by the sealing ring 502.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 Both sides of the connector 5 are provided with connecting rings 507. The ends of the first pipe 2 and the second pipe 4 are provided with grooves 204. When the connector 5 is installed in the first pipe 2, the connecting rings 507 of the connector 5 are embedded in the grooves 204 on one side of the first pipe 2. The setting of the connecting rings 507 increases the connection strength of the connector 5, so that when the connector 5 is installed inside the first pipe 2, the inner tube 501 will not break due to external pressure on the connector 5, thereby increasing the service life of the connector 5.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3The outer wall of the connecting ring 507 is provided with four sets of limiting blocks 506. One end of the first pipe 2 is provided with a limiting groove 205. Personnel can insert the limiting block 506 into the limiting groove 205 to accurately install the connector 5, so that the hole on the connector 5 is aligned with the hole on the connecting plate 203 at the end of the first pipe 2, thereby facilitating personnel to use bolts to install the connector 5 onto the pipe and the connecting plate 203.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The first pipe 2, the second pipe 4 and the connector 5 are connected by bolts. The first pipe 2, the second pipe 4 and the connector 5 are provided with four sets of holes. The connector 5 is connected to the first pipe 2 and the second pipe 4 by bolts.

[0041] In practical operation, when the gas meter 3 is installed on the first pipe 2 on the outer wall of the gas pipeline 1, the sealing tube 504 on one side of the connector 5 is first inserted into the inside of the first pipe 2. When the end of the sealing tube 504 contacts the protective block 201, the convex ring 505 is inserted into the groove 202 on the inner wall of the first pipe 2. When the sealing tube 504 is about to contact the protective block 201, the limiting block 506 on one side of the connector 5 is embedded into the limiting groove 205 at the end of the first pipe 2, so that the connecting ring 507 is inserted into the groove 204, thereby completing the installation connection between the connector 5 and the first pipe 2. Then, the second pipe 4 at the bottom of the gas meter 3 is sleeved on the inner tube 501 on one side of the connector 5, and the connecting ring 507 on one side of the connector 5 is embedded into the groove 204 inside the second pipe 4, thereby installing the gas meter 3 onto the gas pipeline 1.
