Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a gas manifold and gas transmission station. Background Technology

[0002] In the collection and distribution of natural gas, multiple manifolds are required for the collection, distribution and transportation of gas. They are one of the important components in pressure pipelines. A manifold is made by manufacturing several branch pipes on an integral steel pipe or main cylinder. The traditional method of connecting branch pipes to manifolds is usually by drawing. However, the thickness and length of the drawn branch pipes are limited and cannot meet the length requirements of the branch pipes.

[0003] In the prior art, a gas manifold is disclosed, including a pipe fitting and a pipe body. The pipe body has a connection port, and the pipe fitting extends into the connection port and is welded to the outer surface of the pipe body by a butt weld to accommodate branch pipes of different lengths. However, the contact surface between the pipe fitting and the connection port is curved, which results in high stress at the weld between the pipe fitting and the pipe body, which may cause welding hazards and welding defects are prone to occur at the weld. This may lead to gas leakage at the weld or damage to the pipe body or pipe fitting during the welding process, affecting the reliability and stability of the gas manifold. Utility Model Content

[0039] This embodiment provides a gas manifold, such as Figures 1-3As shown, the gas used for collecting and distributing gas in a gas pipeline includes a cylinder assembly 1 and an extension pipe assembly 2. The cylinder assembly 1 includes a main cylinder 11, at least one inlet pipe 12, and at least one distribution pipe 13. Along the axial direction of the main cylinder 11, the opposite ends of the main cylinder 11 are sealed. A gas collecting chamber is provided inside the main cylinder 11. At least one inlet pipe 12 and at least one distribution pipe 13 are formed by drawing from the cylinder wall of the main cylinder 11. At least one inlet pipe 12 and at least one distribution pipe 13 are spaced apart. At least one inlet pipe 12 and at least one distribution pipe 13 are both connected to the gas collecting chamber. The extension pipe assembly 2 includes at least two extension pipe fittings 21. At least two extension pipe fittings 21 have channels inside.

[0040] An air inlet pipe 12 and an air distribution pipe 13 are drawn from the wall of the main cylinder 11, and extension fittings 21 are fixedly connected to both the air inlet pipe 12 and the air distribution pipe 13. The drawn air inlet pipe 12 and the air distribution pipe 13 result in a reasonable structure at the connection between the cylinder wall and the air inlet pipe 12 and the air distribution pipe 13, with uniform stress, good integrity, and high strength. This avoids welding defects in welded connections and ensures the reliability of the gas collection pipe. At the same time, the extension fittings 21 extend the length of both the air inlet pipe 12 and the air distribution pipe 13, meeting the length requirements. It should be noted that the diameter of the main cylinder 11 is not limited.

[0041] Optionally, in this embodiment, the gas in the gas pipeline is natural gas. In other embodiments, the gas in the gas pipeline may also be coal gas, etc. No limitation is imposed here.

The at least two air inlet pipes 12 are spaced apart along the axial direction of the main cylinder 11, and the at least one air distribution pipe 13 is disposed between two adjacent air inlet pipes 12.

[0045] Specifically, such as Figure 1 As shown, in this embodiment, the main cylinder 11 is formed by drawing three air inlet pipes 12 and six air distribution pipes 13. The three air inlet pipes 12 are spaced apart along the axial direction of the main cylinder 11, and the six air distribution pipes 13 are spaced apart along the axial direction of the main cylinder 11. Three air distribution pipes 13 are arranged between two adjacent air inlet pipes 12.

[0049] Furthermore, such as Figure 1 and Figure 2 As shown, the air inlet pipe 12 and the air distribution pipe 13 are arranged at an angle along the circumferential direction of the main cylinder 11.

[0050] Optionally, such as Figure 2 As shown, in this embodiment, the angle between the inlet pipe 12 and the distribution pipe 13 along the circumferential direction of the main cylinder 11 is 180°, meaning that the inlet pipe 12 and the distribution pipe 13 are arranged opposite each other, allowing the gas input from the inlet pipe 12 to be directly discharged from the opposite side, thus optimizing the gas flow direction in the gas collecting chamber. In other embodiments, the angle between the inlet pipe 12 and the distribution pipe 13 can be flexibly adjusted according to different operating conditions, and can be 45°, 90°, or 120°, etc., to achieve the best gas transmission and distribution effect, fully demonstrating the flexibility and adaptability in practical applications.
