[0002] In the modern energy supply system, natural gas, as a clean and efficient energy source, its safe and stable transportation is of great importance. In the natural gas pipeline transportation network, the sub - transmission link is a key node for distributing natural gas to different users or branch pipelines. The pressure balance regulation in this link directly affects the safety and stability of natural gas transportation. If the sub - transmission pressure fluctuates too much, it will not only reduce the transportation efficiency of natural gas, but may also cause safety accidents such as pipeline leakage and equipment damage, and even affect the normal use of end - users.

[0003] However, the traditional natural gas pipeline pressure regulating devices in the market have the following defects:

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4 This utility model provides an automatic pressure balancing and regulating device for natural gas pipeline distribution, which includes a main pipeline 1, a first branch pipeline 2, a second branch pipeline 3, an installation pipeline 4, a pressure regulating structure 5, and a pressure gauge 6.

[0028] The right end of the main pipe 1 is fixedly connected to a first branch pipe 2 and a second branch pipe 3. The upper surface of the first branch pipe 2 and the second branch pipe 3 is provided with an installation pipe 4. The top end of the installation pipe 4 is fixedly connected to a sealing plate 401, and a through hole is opened in the middle of the sealing plate 401.

[0029] The internal structure of the installation pipe 4 is equipped with a pressure regulating structure 5, which includes a motor 501, a first fixing rod 502, a second fixing rod 503, a first rotating shaft 504, a limiting plate 5041, a fixing component 505, a locking block 5051, a second rotating shaft 506, a locking groove 5061, a rotating wheel 507, a threaded rod 508, a pressure plate 509, a spring 5010, a connecting column 5011, and a sealing ball 5012.

[0030] The motor 501 is positioned above the installation pipe 4. A first fixing rod 502 and a second fixing rod 503 are fixedly connected to the upper surface of the installation pipe 4. The first fixing rod 502 and the second fixing rod 503 pass through the motor 501. Nuts are fixed at the connection between the motor 501 and the first fixing rod 502 and the second fixing rod 503. A first rotating shaft 504 is fixedly connected to the output end of the motor 501.

[0031] A limiting plate 5041 is fixedly connected to the bottom end of the first rotating shaft 504. A fixing member 505 is provided on the outer surface of the first rotating shaft 504. The fixing member 505 is sleeve-shaped. The limiting plate 5041 is located inside the fixing member 505. A locking block 5051 is fixedly connected inside the fixing member 505. A second rotating shaft 506 is connected to the bottom end of the first rotating shaft 504. A locking groove 5061 is fixedly connected to the top outer surface of the second rotating shaft 506. The locking groove 5061 and the locking block 5051 fit together. A rotating wheel 507 is fixedly connected to the bottom outer surface of the second rotating shaft 506. A threaded rod 508 is fixedly connected to the bottom end of the second rotating shaft 506.

[0032] The upper outer surface of the threaded rod 508 is threaded, and the lower outer surface of the threaded rod 508 is a sliding rod. A fixing plate 5013 is threadedly connected to the upper outer surface of the threaded rod 508, and a sealing plate 401 is slidably connected to the lower outer surface of the threaded rod 508. A pressure plate 509 is rotatably connected to the bottom end of the threaded rod 508. A sealing ring made of rubber is installed on the outer surface of the pressure plate 509. A spring 5010 is fixedly connected to the bottom end of the pressure plate 509. A connecting post 5011 is fixedly connected to the bottom end of the spring 5010. A sealing ball 5012 is fixedly connected to the bottom end of the connecting post 5011.

[0033] The above structure, controlled by motor 501, rotates the first rotating shaft 504. The fixing member 505 connects and fixes the first rotating shaft 504 and the second rotating shaft 506, causing the first rotating shaft 504 to drive the second rotating shaft 506 to rotate together. This causes the threaded rod 508 to rotate downwards, pressing the pressure plate 509 downwards, causing the sealing ball 5012 to move into the pipe, sealing the pipe and controlling the pressure inside. If motor 501 is damaged, the fixing member 505 can be removed from the second rotating shaft 506, allowing the first rotating shaft 504 and the second rotating shaft 506 to rotate together. The shaft 506 is separated, and then the rotation of the second shaft 506 is controlled by rotating the wheel 507 to control the pressure inside the pipeline. If the motor 501 fails or the worker does not notice the pressure increase in time, the pressure inside the main pipeline 1 will increase. The sealing ball 5012 can be lifted by the spring 5010 to release some pressure and control the pressure inside the main pipeline 1. If the first branch pipeline 2 and the second branch pipeline 3 are to be completely sealed, the spring 5010 can be pressed to the bottom by the pressure plate 509 so that the sealing ball 5012 can completely seal the pipeline.

[0034] A pressure gauge 6 is installed on the right side of the installation pipe 4. A pressure guide pipe 601 is connected to the upper surface of the first branch pipe 2 and the second branch pipe 3. A pressure gauge 6 is connected to the upper surface of the pressure guide pipe 601. The pressure gauge 6 has green, yellow and red markings inside.

[0035] Working principle: The motor 501 controls the rotation of the first rotating shaft 504. The fixing part 505 connects and fixes the first rotating shaft 504 and the second rotating shaft 506, so that the first rotating shaft 504 drives the second rotating shaft 506 to rotate together, and the threaded rod 508 rotates downward, causing the pressure plate 509 to press down, so that the sealing ball 5012 moves into the pipeline, sealing the pipeline and thus controlling the pressure inside the pipeline. If the motor 501 is damaged, the fixing part 505 can be removed from the second rotating shaft 506, so that the first rotating shaft 504 and the second rotating shaft 506 are separated. Then, by rotating the rotating wheel 507, the rotation of the second rotating shaft 506 is controlled to complete the control of the pressure inside the pipeline.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
