[0002] Once a city's gas companies reach a consolidation agreement, each city will have a single gas supply system. Consequently, the gas pipeline networks previously owned by different gas companies will be merged, creating a single, citywide gas supply network. Prior to the consolidation, small gas companies often operated at insufficient pressure to meet city demand due to limited construction and storage capacity. After the consolidation, the overall operating pressure of these pipelines will need to be increased to meet the needs of urban development.

[0003] Currently, there is no effective solution for boosting the pressure of gas pipeline networks. How to boost the pressure of gas pipeline networks safely and effectively has become a technical problem that needs to be solved urgently.

The test results include at least the service time and operating status parameters of the pipeline sections in each area. The pipeline section in the selected area has the longest service time and the worst operating status.

[0016] In some embodiments, the partial gas pipe section is the pipe section with the least number of users or the least impact on users in the selected area.

[0017] In some embodiments, the step of boosting the voltage of all the zones in stages includes:

[0018] Determine the pipeline operating pressure after the pressure boost is completed at each stage;

[0024] In addition, to achieve the above-mentioned purpose, the present invention further proposes a gas pipe network pressure boosting device, the gas pipe network pressure boosting device comprising:

[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The embodiment of the present invention provides a method for boosting gas pipe network pressure, referring to Figure 1 , Figure 1 This is a flow chart of a first embodiment of a gas network pressure boosting method according to the present invention.

[0040] In this embodiment, the gas network pressure boosting method includes the following steps:

[0041] Step S10: After the design pressure of the pipeline network and the pipeline network-related equipment meet the pressure-boosting requirements, the area of ​​the planned pressure-boosting pipeline network is divided into zones.

[0042] In this embodiment, the executor of this embodiment is a gas pipe network boosting device, wherein the gas pipe network boosting device has functions such as data processing, data communication and program running. The gas pipe network boosting device can be a computer terminal device or other network device, and of course it can also be other devices with similar functions. This embodiment does not limit this.

[0043] It should be noted that once a gas company integration agreement is reached within a city, a one-city, one-company gas supply system will be established. Gas pipelines previously belonging to different gas companies throughout the city will also be merged, forming a single citywide gas supply network. Prior to the integration, small gas companies had limited construction and storage capabilities, and the operating pressure of their gas pipelines often failed to meet the city's needs. After the integration, the operating pressure of this portion of the pipeline network will need to be increased overall to meet the needs of urban development. Currently, there is no effective solution for boosting the pressure of gas pipelines, and how to safely and effectively boost the pressure of gas pipelines has become a pressing technical challenge.

[0044] This embodiment divides the area of ​​the planned boosted pipeline network into zones after the design pressure of the pipeline network and the pipeline network-related equipment meet the boosting requirements; selects part of the gas pipeline section in one area from the divided areas for a boosting test, and restores the gas pipeline section to the original operating pressure after the test is completed; if the selected area meets the boosting test requirements, all areas are boosted as a whole in stages, and the pipeline network is checked for leaks during the boosting process, which solves the problem of insufficient pipeline supply capacity of small gas companies, improves the gas supply capacity of the existing pipeline network, and ensures gas supply safety. The boosting of the gas pipeline network also meets the essential requirements of the intensification and scale of urban gas business, and can be specifically achieved in the following ways.

[0045] In a specific implementation, in this embodiment, before boosting the pressure, it is necessary to first ensure that the design pressure of the pipeline network and the pipeline network-related equipment meet the boosting requirements.

[0046] Specifically, this example illustrates a proposed boosted pipeline network consisting of two components: 8.2 km of LPG steel pipe originally used by a small gas utility and 9.5 km of PE pipe. The LPG pipeline network has a design pressure of 0.3 MPa (medium pressure Grade A: 0.2-0.4 MPa, medium pressure Grade B: 0.01-0.2 MPa), and the PE pipe has a design pressure of 0.4 MPa. The current operating pressure of these two components is 0.07 MPa, and the proposed pressure increase to 0.25 MPa meets the proposed boosting technical requirements (i.e., the network design pressure > operating pressure).

[0047] For pipeline network-related equipment, it is necessary to clarify the number and condition of the pressure regulating equipment, valves, etc. in the existing pipeline network, and then maintain or transform the relevant equipment to meet the pressure increase demand. Specifically, the proposed medium-pressure pipeline network adopts the pressure regulation method of "regional pressure regulation, low-pressure into households". There is no indoor pressure regulator, and it is a building pressure regulating box or building pressure regulating cabinet. The scope of the proposed boosted pipeline network involves 68 in-service valves, 15 condensate cylinders, and 72 pressure regulating equipment. Before the pressure is increased, it is necessary to complete a comprehensive inspection, maintenance, maintenance and transformation of the proposed medium-pressure pipeline network and its ancillary facilities. The specific measures are as follows:

[0048] ① For medium-pressure pipelines to be boosted: Patrol workers will use S660 pipe detectors, and emergency response teams will use laser detectors to conduct a comprehensive inspection of the proposed boosted pipelines and equipment. Laser methane leak detection vehicles will also be deployed to inspect pipelines on the roadway. The goal is to detect and address potential leaks in the pipelines before the actual boost. Two inspections will be conducted, the last a few days before the planned boost.

[0049] ② Valves and condensate tanks: including pumping out water from valve wells and clearing silt, and comprehensively checking valves, flanges, relief ball valves, and threaded connections for leaks, addressing related hidden dangers and keeping records;

[0050] ③ Pressure regulating equipment: Check whether the equipment is leaking, whether the threaded interface of the pressure gauge is loose, whether the pressure regulator, filter, valve body of the pressure regulating equipment, flange gaskets at the connection are aging and leaking, etc. If leaks, suspected leaks, loose interfaces, aging gaskets and other hidden dangers are found, repair them immediately or report the gas outage and replace them. Test the shut-off valves and safety valves of pressure regulating equipment for key users, long-term operation, and frequent failures during daily operation. Replace any problematic equipment parts and keep records;

[0051] ④ Pressure reducing valve installed behind the riser tenon: Check the installation of pressure reducing valve behind the riser tenon of the pipe network, communicate with the user to understand the subsequent gas demand, and seal and remove it if there is no need to use gas anymore, eliminate safety hazards and record them;

[0052] ⑤ Old pipelines without potential users: Several sections of medium-pressure pipelines without potential users in the original pipeline network will be blocked and abolished, the pipeline network layout will be optimized, and potential leakage hazards will be eliminated and recorded.

[0053] Furthermore, after the pressure-boosting demand is met, in this embodiment, the area of ​​the planned pressure-boosting network is divided into zones, and the distribution and equipment connection of the planned pressure-boosting network are specifically determined. The distribution and equipment connection conditions at least include the distribution and connection of pipeline directions and network-related equipment; based on the distribution and equipment connection conditions, the area of ​​the planned pressure-boosting network is divided into zones according to preset area boundaries. The preset area boundaries need to facilitate the investigation of hidden dangers, risk control and rapid positioning during and after pressure boosting. The preset area boundaries may include rivers, railways, main roads and overpasses. In this embodiment, further combined Figure 2 The following example illustrates partitioning. Figure 2 As shown, Figure 2 Only the gas main is shown in the figure. Due to the influence of rivers and railways, in order to ensure the smooth progress of the pressure boosting process, the medium-pressure pipeline network in the boosting area is divided into the following three areas: ① Area 1: south of the river and east of the railway, the pipeline network in this area is LPG steel pipe + PE pipe; ② Area 2: west of the railway, the pipeline network in this area is LPG steel pipe; ③ Area 3: north of the river and east of the railway, the pipeline network in this area is PE pipe.

[0054] Step S20: Select a portion of the gas pipe section in one area from the divided areas to perform a pressure boost test, and restore the gas pipe section to the original operating pressure after the test is completed.

[0055] It should be noted that before the formal pressure boost, in order to verify the reliability and safety of the pressure boosting scheme, test the cooperation of the pressure boosting team, and improve the efficiency of the formal pressure boosting stage, a gas pipeline section with no users in an area is selected for pressure boosting testing in this embodiment.

[0056] Specifically, the pipe sections in each area can be inspected; based on the inspection results, part of the gas pipe sections in one area are selected from several areas for pressure boost testing. The inspection results include at least the service time and operating status parameters of the pipe sections in each area. The pipe sections in the selected area have the longest service time and the worst operating status. It should be noted that pipe sections with long service time and poor condition are selected for pressure boost testing. If these pipe sections meet the test requirements, then other pipe sections also meet the requirements.

[0057] Furthermore, the selected pipe sections in this embodiment are the pipe sections with the least number of users or the least impact on users, so that when the subsequent pressure test is performed, the impact on residents' gas consumption can be minimized to the greatest extent.

[0058] Reference Figure 3 As shown, the specific test plan is as follows: The test plan is as follows: ① Install a pressure regulating gas flow device at branch valve 1, close branch valve 2 as a temporary isolation valve, and install discharge pipes and pressure gauges on both sides of the vent of branch valve 2 to monitor the pressure and record it in detail (Table 1). ② Conduct a three-stage (i.e., 0.07MPa→0.12MPa→0.17MPa→0.25MPa) pressure increase test on the test section of the second gas pipeline in the area through the gas pipe of branch valve 1 (refer to Figure 4 (as shown), check the pipeline network operation, monitor the pressure at Valve 2, and record it in detail (Table 1). ③ After the test is completed, close the gas flow equipment at Valve 1 and gradually discharge the pressure to 0.07 MPa. Open Branch Valve 2. Remove all pressure-regulating gas pipes and discharge pressure monitoring equipment from Valve 1, restore the original gas supply mode (0.07 MPa) for the test section of Area 2 gas pipeline, and complete the pressure increase test.

[0061] Step S30: If the selected area meets the pressure boost test requirements, all areas are pressure boosted in stages, and the pipeline network is tested for leaks during the pressure boost process.

[0062] After the test is completed, all the zones in this embodiment are officially boosted. The specific boosting process is to boost the voltage in stages, for example Figure 5 As shown, this embodiment is divided into the first stage, the second stage and the third stage. Each stage has a pipeline operating pressure after the boost is completed. For example, the first stage corresponds to P1, the second stage corresponds to P2, and the third stage corresponds to P 最终 The pipeline operating pressure after each stage of boosting is determined by the pressure difference between the original pipeline operating pressure and the target pipeline operating pressure in all areas and the preset ratio corresponding to each stage. For example, in the first stage: P 原始→P1, P1=P 原始 +30%(P 最终 -P 原始 ), the second stage: P1→P2, P2=P 原始 +60%(P 最终 -P 原始) , the third stage: P2→P 最终 , P2=P 原始 +100%(P 最终 -P 原始 ), P 最终 -P 原始 The pressure difference is represented by 30%, 60% and 100% as preset ratios. The preset ratio corresponding to the first stage is 30%, the preset ratio corresponding to the second stage is 60%, and the preset ratio corresponding to the third stage is 100%. It should be noted that the ratio is only an example and can be adjusted accordingly according to the actual pressure increase requirements in actual situations. This is not limited in this embodiment.

[0063] This embodiment divides the area of ​​the planned boosted pipeline network into zones after the design pressure of the pipeline network and the pipeline network-related equipment meet the boosting requirements; selects part of the gas pipeline section in one area from the divided areas for a boosting test, and restores the gas pipeline section to the original operating pressure after the test is completed; if the selected area meets the boosting test requirements, all areas are boosted as a whole in stages, and the pipeline network is checked for leaks during the boosting process, which solves the problem of insufficient pipeline supply capacity of small gas companies, improves the gas supply capacity of the existing pipeline network, and ensures gas supply safety. The boosting of the gas pipeline network also meets the essential requirements of the intensification and scale of urban gas business.

[0064] In addition, an embodiment of the present invention further provides a storage medium on which a gas network pressure boosting program is stored. When the gas network pressure boosting program is executed by a processor, the steps of the gas network pressure boosting method described above are implemented.

[0069] The boost module 30 is used to boost the pressure of all the areas in stages if the selected area meets the boost test requirements, and detect whether there is leakage in the pipeline network during the boost process.
