Description

Technical Field

[0001] This utility model relates to the field of gas pipe technology, specifically a gas pipe with strong aging resistance. Background Technology

[0002] Gas pipes are pipeline facilities used to transport natural gas. They are crucial in people's lives and industrial production, safely and efficiently delivering natural gas, coal gas, and other gas-using gases to households and various gas-consuming locations. Gas pipes are made of various materials, the most common being steel pipes and polyethylene (PE) pipes. Steel pipes are high-strength and pressure-resistant, suitable for long-distance and complex environments; PE pipes are corrosion-resistant and flexible, often used for urban gas connections. To ensure safety, the design, installation, and maintenance of gas pipes are subject to strict regulations, requiring regular inspections to prevent leaks and other problems, ensuring a stable gas supply and the safety of users' lives and property.

[0003] After prolonged use, gas pipes inevitably age due to oxidation in the air, leading to a reduced lifespan. However, adding a protective structure to the surface of the gas pipe makes it inconvenient to disassemble later. Therefore, a structure that facilitates gas pipe aging and easy disassembly is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a gas pipe with strong aging resistance, including a main pipe, a protective film on the surface of the main pipe, a flange fixedly connected to the right end of the main pipe, an mounting plate fixedly connected to the side of the flange near the main pipe, a threaded sleeve fixedly connected to the top of the mounting plate, a threaded rod threadedly connected inside the threaded sleeve, a handle fixedly connected to the top of the threaded rod, a connecting plate one fixedly connected to the bottom of the threaded rod, a limit sleeve fitted on the surface of the connecting plate one, a connecting plate two fitted inside the limit sleeve, and an arc-shaped pressing plate fixedly connected to the bottom of the connecting plate two.

[0005] The above technical solution involves setting a protective film and wrapping it around the surface of the main pipe. Then, by rotating the handle, the threaded rod rotates, and the handle moves under the action of the threaded sleeve until the bottom of the first connecting plate contacts the top of the second connecting plate. Continuing to rotate the threaded rod, the surface of the arc-shaped pressing plate contacts the surface of the protective film, fixing the protective film to the surface of the main pipe and protecting it. At the same time, the threaded rod also facilitates the subsequent removal of the protective film.

[0006] As a further improvement to the above scheme, the number of flanges is set to two, and the two flanges are evenly distributed on the surface symmetrically around the top center of the main pipe. The number of mounting plates is set to three, and the three mounting plates are distributed in a circle around the side of the flanges closest to the main pipe.

[0007] With the above technical solution, the two flanges are symmetrically and evenly distributed on the surface around the top center of the main pipe. This symmetrical distribution makes the connection more stable and the stress more even. The three mounting plates are circumferentially distributed around the side of the flanges closest to the main pipe, which makes the connection structure more robust. The protective film is supported and fixed from multiple directions, and the stress is evenly distributed to ensure its stability.

[0008] As a further improvement to the above solution, the threaded rod passes through the bottom of the mounting plate, the second connecting plate is located below the first connecting plate, and the arc-shaped pressing plate is concentric with the main pipe.

[0009] Through the above technical solution, the threaded rod penetrating the mounting plate can ensure the stability when the arc-shaped pressing plate moves up and down by rotating the handle. The second connecting plate is located below the first connecting plate and the arc-shaped pressing plate is concentric with the main pipe, which can ensure that the pressing of the arc-shaped pressing plate on the protective film is uniform and accurate, avoiding eccentric pressing that causes local deformation or wear of the main pipe, which is conducive to maintaining the structural integrity of the main pipe and thus enhancing the aging resistance.

[0010] As a further improvement to the above solution, an installation groove is provided at the end of the flange away from the main pipeline, and a sealing gasket is snapped into the installation groove.

[0011] The above technical solution ensures that the sealing gasket inside the installation groove prevents gas leakage and guarantees the internal sealing of the gas pipe. A well-sealed environment reduces the entry of external impurities into the pipe, preventing accelerated aging of the main pipe due to chemical reactions or physical wear between impurities and gas.

[0012] As a further improvement to the above solution, the height of the sealing gasket is greater than the height of the mounting groove.

[0013] The above technical solution ensures that the gasket height is greater than the mounting groove height, allowing the gasket to be fully compressed during connection. This better fills the gaps in the connection area, improves the sealing effect, further protects the internal environment of the main pipeline, and reduces the impact of aging factors.

[0014] As a further improvement to the above solution, an upper pressing plate is sleeved on the surface of the main pipe, and a lower pressing plate is hinged to the bottom of the upper pressing plate. Bolts are provided inside the upper pressing plate.

[0015] As a further improvement to the above solution, the bottom of the bolt penetrates through the bottom of the lower pressing plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention involves setting a protective film, which is wrapped around the surface of the main pipe. Then, by rotating the handle, the threaded rod rotates, and the handle moves under the action of the threaded sleeve until the bottom of the first connecting plate contacts the top of the second connecting plate. By continuing to rotate the threaded rod, the surface of the arc-shaped pressing plate contacts the surface of the protective film, fixing the protective film to the surface of the main pipe and protecting it. At the same time, the threaded rod also facilitates the subsequent removal of the protective film.

[0018] This invention utilizes a sealing gasket to seal the connection between two flanges when connecting pipes, ensuring the safety of gas flow within the pipe. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5This embodiment of a gas pipe with strong aging resistance includes a main pipe 1, a protective film 2 on the surface of the main pipe 1, a flange 3 fixedly connected to the right end of the main pipe 1, an mounting plate 4 fixedly connected to the side of the flange 3 near the main pipe 1, a threaded sleeve 5 fixedly connected to the top of the mounting plate 4, a threaded rod 6 threadedly connected inside the threaded sleeve 5, a handle 7 fixedly connected to the top of the threaded rod 6, a connecting plate 8 fixedly connected to the bottom of the threaded rod 6, a limiting sleeve 9 fitted on the surface of the connecting plate 8, a connecting plate 10 fitted inside the limiting sleeve 9, and an arc-shaped pressing plate 11 fixedly connected to the bottom of the connecting plate 10. The protective film 2 is wrapped around the surface of the main pipe 1. Then, by rotating the handle 7, the handle 7 drives the threaded rod 6 to rotate. The rotation of the handle 7 moves under the action of the threaded sleeve 5 until the bottom of the connecting plate 8 contacts the top of the connecting plate 10. Then, by continuing to rotate the threaded rod 6, the surface of the arc-shaped pressing plate 11 contacts the surface of the protective film 2, fixing the protective film 2 to the surface of the main pipe 1 and protecting the main pipe 1.

[0028] There are two flanges 3, which are symmetrically and evenly distributed on the surface around the top center of the main pipe 1. There are three mounting plates 4, which are distributed in a circle around the side of the flanges 3 closest to the main pipe 1.

[0029] The threaded rod 6 passes through the bottom of the mounting plate 4, the second connecting plate 10 is located below the first connecting plate 8, and the arc-shaped pressing plate 11 is concentric with the main pipe 1.

[0030] The flange 3 has an installation groove 12 at the end away from the main pipe 1, and a sealing gasket 13 is snapped into the installation groove 12.

[0031] The height of the sealing gasket 13 is greater than the height of the mounting groove 12.

[0032] The surface of the main pipe 1 is fitted with an upper pressing plate 14, and the bottom of the upper pressing plate 14 is hinged to a lower pressing plate 15. Bolts 16 are installed inside the upper pressing plate 14.

[0033] The bottom of bolt 16 penetrates the bottom of the lower pressing plate 15.

[0034] The implementation principle of a gas pipe with strong aging resistance in this application embodiment is as follows: Before installing the gas pipe, the protective film 2 is first wrapped around the surface of the main pipe 1. Then, by rotating the handle 7, the handle 7 drives the threaded rod 6 to rotate. The handle 7 rotates and moves under the action of the threaded sleeve 5 until the bottom of the connecting plate 1 8 contacts the top of the connecting plate 2 10. Then, the threaded rod 6 is rotated continuously, and the surface of the arc-shaped pressing plate 11 contacts the surface of the protective film 2, fixing the protective film 2 to the surface of the main pipe 1 to protect the main pipe 1. At the same time, the threaded rod 6 also facilitates the subsequent disassembly of the protective film 2.

[0035] After the protective film 2 is fixed, the upper pressing plate 14 and the lower pressing plate 15 are connected by bolts 16, and the inner surfaces of the upper pressing plate 14 and the lower pressing plate 15 are brought into contact with the protective film 2 to fix the protective film 2 a second time.

[0036] When connecting pipes, the gasket 13 seals the connection between the two flanges 3, ensuring the safety of gas flow inside the pipe.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
