Description

Technical Field

[0001] The utility model relates to the technical field of compressed air systems, and more specifically to a device for stabilizing pressure at the end of a gas system pipeline. Background Art

[0002] Compressed air systems are widely used in various fields such as petroleum, chemical industry, metallurgy, thermal power, chemical fiber, etc. After the air is pressurized by the air compressor, it is transported to the gas-using equipment at each end through the compressed air pipeline network.

[0003] Many existing compressed air systems do not respond to fluctuations in gas consumption at the terminal gas-using equipment and adopt direct open-type gas supply. As a result, once there is a significant fluctuation in terminal gas consumption, the entire pipeline network will be affected, causing fluctuations in the entire compressed air system.

[0004] In order to solve the above problems, the utility model patent with publication number CN207750742U discloses a terminal gas optimization device which is beneficial to the pressure stabilization of the compressed air main network. The utility model collects the pressure values ​​of the main network and the gas tank in real time, compares them with the preset pressure values, and fully utilizes the surplus compressed air in the local gas tank within the gas supply requirements of the terminal equipment to cope with the sudden change in gas volume demand of the terminal gas-using equipment. By adjusting the opening of the electric control valve, the impact of the change on the main network is reduced and mitigated.

[0005] However, when the above-mentioned terminal gas optimization device is actually used, it may be necessary to replace tanks of different volumes during the process of regulating the pressure at the end of the pipeline. When replacing the tank, staff are required to assist in alignment and then connect it through flanges, which greatly affects the installation efficiency. Utility Model Content

[0042] Reference Figure 2 As shown, specifically, a direct-flow stop valve 18 is fixedly connected to the right side of the three-way pipe 1, and a pressure gauge 19 is installed on the outside of the three-way pipe 1 to accurately detect the air pressure of the pipeline.
