[0001] The invention relates to the technical field of gas supply, and in particular to a gate station delivery system. Background Art

[0002] The gate station is the gas source point of the urban transmission and distribution system, and is also the gas distribution station where the long-distance natural gas pipeline enters the urban gas network. Its task is to receive the gas transmitted by the long-distance pipeline, filter, pressure regulate, meter, odorize, and distribute it in the station, and then safely and stably transmit the gas that meets the standards to each user. The existing gate station transmission system usually uses a main pipe extending from the gate station to the outside, and distributes gas through multiple branch pipelines when approaching the user area. Although this transmission system simplifies the gate station transmission system, there are the following problems in actual operation:

[0003] 1. The transmission system has complicated and numerous branch lines; the huge branch network increases the workload of daily management and maintenance, resulting in low management efficiency.

[0004] 2. The dispatch response is slow and the emergency handling capabilities are insufficient. When a branch experiences insufficient or interrupted gas supply, it is difficult to make quick adjustments, affecting user experience and safety.

[0005] 3. Since gate stations are usually located in the suburbs of cities and are geographically remote, the cost and technical difficulty of accessing the power grid increase, and they are easily affected by the external environment, resulting in unstable power supply, affecting the safe and stable operation of the gate station transportation system and increasing maintenance costs. Summary of the invention

[0019] Beneficial effects: Each outbound pipeline is equipped with a regional metering control cabinet to facilitate the separate management and monitoring of gas usage in different areas, which helps to improve operational efficiency, realize the refined management of gas supply in different areas, and adjust the gas supply strategy according to the needs of different areas. Intelligent control valves are set on the gas branch pipes to achieve independent control of different gas branch pipes. A third pressure monitoring device is set near the end of each pipeline to monitor the pressure of the entire gas transmission system, fully grasp the pressure distribution in the system, and promptly detect possible pressure anomalies.

The gate station controller 13, the regional metering control cabinet 16, the third intelligent control valve 17, and the third pressure monitoring device 18 are respectively connected to the intelligent control system through wireless connection. The wireless connection method can be connected using a wireless local area network. The regional metering control cabinet 16 adopts a DMA regional metering control cabinet, and the DMA regional metering control cabinet is integrated with flow monitoring units, pressure monitoring units, data transmission units and other equipment, which can collect and transmit gas pipeline data in real time. The third intelligent control valve 17 includes a valve well, and a valve is arranged in the valve well.

The first intelligent control valve 6 is located on the odorized liquid pipeline, and the amount of odorized liquid added is controlled by controlling the opening of the first intelligent control valve 6.

[0035] Here’s how to use it:

[0036] High-pressure gas is delivered to the gate station through the inlet pipeline 1, filtered and impurities are removed through the filter 2, and enters the gate station transmission pipeline through the electric control valve 3. The pressure and flow monitoring device of the electric control valve 3 sends the real-time pressure and flow of the high-pressure gas entering the station to the gate station controller 13. The high-pressure gas is depressurized by the intelligent pressure regulating valve 4, mixed with the odorizing liquid through the mixer 7, and the odorized gas enters the manifold 10 through the transmission pipeline in the gate station and then is delivered to different areas through the outlet pipeline 19. At the same time, the pressure of the pipeline in the gate station is monitored in real time by the first pressure monitoring device 8, and the pressure of the outlet pipeline 19 is monitored in real time by the second pressure monitoring device 12, and gas allocation is realized through the gate station controller 13. The gas supply in the area is controlled by the DMA area metering control cabinet 16.

[0037] In this embodiment, three outlet pipelines 19 are provided on the manifold 10, namely the first outlet pipeline 1901, the second outlet pipeline 1902, and the third outlet pipeline 1903. The first outlet pipeline 1901 is an industrial pipeline, and the second and third outlet pipelines are civil pipelines. The diameter of the first outlet pipeline 1901 is larger than the diameters of the second and third outlet pipelines. The second pressure monitoring devices 12 respectively provided on the first, second and third outlet pipelines send the pressure information of each outlet pipeline to the gate station controller 13 in real time. When the gas usage in the area connected to the first outlet pipeline 1901 increases sharply and the pressure in the first outlet pipeline 1901 drops to the set value, the gate station controller 13 first adjusts the opening of the second intelligent control valve 11 of the first outlet pipeline 1901 to restore its pressure to the set value; if the pressure in the first outlet pipeline 1901 does not reach the set value, the opening of the second intelligent control valve 11 of the second and third outlet pipelines is adjusted to ensure that the pressure in the second and third outlet pipelines 1903 is within the set value range while the remaining gas is allocated to the first outlet pipeline 1901; if the pressure in the first outlet pipeline 1901 still does not reach the set value, the electric control valve 3 and the intelligent pressure regulating valve 4 are adjusted to increase the pressure in the manifold 10, thereby making the pressure in the first outlet pipeline 1901 reach the set value. At the same time, the DMA area metering control cabinet 16, the third intelligent control valve 17, and the third pressure monitoring device 18 on the first outlet pipeline 1901 and the downstream pipeline will send real-time monitoring data to the intelligent control system, which will monitor the entire gate station transportation system through the intelligent control system to prevent leakage.
