Description

Technical Field

[0001] The present application relates to the field of gas pipeline networks, and in particular to an intelligent gas pipeline network optimization system. Background Art

[0002] Traditional gas pipeline networks are widely used in the transportation and distribution of natural gas. Their main components include gas storage tanks, pipelines, and various valves. These systems must ensure the safe and stable flow of gas at varying pressures. However, due to the complexity of the system structure and the characteristics of gas, traditional gas pipeline networks often face safety hazards such as uncontrolled pipeline pressure, gas leaks, and pipeline ruptures. Once these problems occur, they can lead to serious accidents and economic losses. Therefore, improving the safety of gas pipeline networks has become a key focus of the industry.

[0003] To improve the safety of gas pipeline systems, existing technologies have proposed a variety of solutions. For example, buffer tanks are installed at key nodes in the pipeline to absorb some pressure fluctuations and reduce the risk of sudden pressure increases. In addition, some technical solutions use stronger materials or increase pipeline wall thickness to enhance the pipeline's pressure resistance and reduce the possibility of safety accidents caused by pipeline damage. At the same time, the use of gas detection systems can detect abnormal changes before leaks occur and issue alarms. These measures have improved the safety of the system to a certain extent.

[0004] While existing technologies have made progress in improving the safety of gas pipeline systems, they still face deficiencies in practical application. For example, increasing pipe wall thickness or using stronger materials can improve the pipeline's pressure resistance, but this often increases system construction and maintenance costs, and can still cause ruptures under extreme pressure conditions. Furthermore, while buffer tanks can absorb some pressure, they still cannot completely prevent explosions caused by excessive internal pressure in the pipeline under rapid pressure changes. Therefore, existing technologies still have certain shortcomings in addressing the problem of explosions caused by excessive internal pressure during operation. Utility Model Content

[0033] The following is combined with Figure 1-4 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] The embodiment of the present application provides an intelligent gas pipeline network optimization system 100, comprising:

[0035] Gas tank 1;

[0036] A gas pipe network structure 2 is connected to the gas storage tank 1, and a return pipe 3 is provided at one end of the gas pipe network structure 2. The return pipe 3 is a triangular structure formed by bending the two ends of a tubular structure. The return pipe 3 includes free ends at both ends. The free ends are welded to the gas pipe network structure 2 and are connected to the gas pipe network structure 2;

[0037] The start-stop structure 4 is provided on the gas pipe network structure 2 and includes a manual stop valve 5 and a gas pressure stop valve 6 which are arranged in parallel.

[0038] Specifically, the intelligent gas network optimization system consists of a gas tank 1, a gas network structure 2, and a start-stop structure 4. The gas tank 1 is used to store and supply gas to ensure a stable source of gas in the system. The gas network structure 2 is connected to the gas tank 1 and is equipped with a return pipe 3 at one end. The tubular structure of the return pipe 3 is bent at both ends to form a triangular structure, and the free end of the return pipe 3 is welded to the gas network structure 2 to ensure the connectivity between the return pipe 3 and the network structure. The triangular design of the return pipe 3 can effectively disperse the pressure fluctuations in the gas flow and reduce the risk of pipeline damage or potential explosion caused by pressure changes. The start-stop structure 4 includes a manual shut-off valve 5 and an air pressure shut-off valve 6 arranged in parallel. The manual shut-off valve 5 provides a manual control option, while the air pressure shut-off valve 6 automatically closes when the system detects a pressure abnormality, thereby preventing excessive pressure from damaging the system. During normal operation, gas is transported from the gas tank 1 through the gas network structure 2. When the system detects an increase in pipeline pressure, the design of return pipe 3 buffers the gas, reducing the pressure within the pipe and preventing potential explosion risks. Simultaneously, pressure shutoff valve 6 automatically closes, cutting off the gas supply and preventing further pressure increases. Manual shutoff valve 5 provides additional manual control in the event of an automatic system failure. This system is suitable for safety-critical applications such as natural gas pipeline networks and industrial gas transportation, ensuring effective system protection in the event of abnormal pressure.

[0039] In a specific example, the gas pipe network structure 2 is a pipe network structure in which multiple pipes are spliced ​​together, and threaded flanges 7 are provided at both ends of the pipes. Multiple pipes are threadedly connected through the threaded flanges 7. The gas pipe network structure 2 includes a first gas pipeline 8 and a second gas pipeline 9. One end of the first gas pipeline 8 is connected to the second gas pipeline 9, and the other end is connected to the gas storage tank 1. A first air pressure shut-off valve 17 is provided at the contact end of the first gas pipeline 8 and the second gas pipeline 9. The return pipe 3 is provided on the first gas pipeline 8, and a start-stop structure 4 is provided at the connection end of the first gas pipeline 8 and the gas storage tank 1.

[0040] Specifically, the gas network structure 2 is a network structure in which multiple pipelines are spliced ​​together, and threaded flanges 7 are provided at both ends of each pipeline, which are connected through threaded flanges 7. The gas network structure 2 includes a first gas pipeline 8 and a second gas pipeline 9, and the first gas pipeline 8 is connected to the second gas pipeline 9, and a start-stop structure 4 is provided at the connection end with the gas tank 1. This design improves the stability and sealing of the pipeline by using threaded flanges 7 to connect the pipelines, and avoids the risk of leakage at the pipeline connection. The setting of the start-stop structure 4 ensures that pressure control and flow management can be performed at the key nodes of the pipeline, thereby improving the overall safety of the system. Through the design of multi-pipe splicing, the network structure can be flexibly adjusted to adapt to different needs. At the same time, the configuration of the start-stop structure 4 ensures effective control of gas flow at key positions. This can reduce the risk of gas leakage and pressure fluctuations, and improve the safety and reliability of the gas network system.

[0041] In a specific example, the second gas pipeline 9 is provided with a gas outlet end 11, which is arranged away from the contact end of the second gas pipeline 9 and the first gas pipeline 8. The gas outlet end 11 is provided with a shunt pipe 13, which is connected to the second gas pipeline 9.

[0042] Specifically, the second gas pipeline 9 is provided with a gas outlet end 11, which is arranged away from the contact end with the first gas pipeline 8, and a diverter pipe 13 is provided on the gas outlet end 11. The diverter pipe 13 is connected to the second gas pipeline 9 and is used to guide the gas flow to other pipelines or equipment. This design allows the gas to be effectively diverted in the pipeline network, improving the flexibility and efficiency of gas transportation, while avoiding the problem of excessive pressure caused by the concentration of gas in a certain pipeline. By providing the gas outlet end 11 and the diverter pipe 13, the gas can be effectively diverted from the second gas pipeline 9 to other parts, optimizing the gas flow path, avoiding excessive load on a single pipeline, and improving the operational flexibility and safety of the system.

[0043] In a specific example, the air pressure shut-off valve 6 includes a sensor 14 provided at one end. The sensor 14 partially extends into the air pressure shut-off valve 6 and is electrically connected to the shut-off valve. The sensor 14 drives the air pressure shut-off valve 6 to open and close.

[0044] Specifically, the air pressure shut-off valve 6 includes a sensor 14 at one end. Sensor 14 partially extends into the air pressure shut-off valve 6 and is electrically connected to the shut-off valve. Sensor 14 monitors the gas pressure within the pipeline in real time. When it detects that the pressure exceeds a set value, sensor 14 drives the air pressure shut-off valve 6 to open and close, promptly shutting off the gas flow and preventing safety hazards caused by excessive pressure. The electrical connection between sensor 14 and the air pressure shut-off valve 6 automates the pressure monitoring and control process, improving the system's response speed and accuracy, and effectively preventing accidents caused by excessive pressure.

[0045] In a specific example, the air pressure shut-off valve 6 includes a pressure gauge 15, which is provided on the sensor 14 and is electrically connected to the sensor 14. When the pressure in the pipe is too high, the shut-off valve cuts off the gas supply from the gas storage tank 1 to the gas pipe network structure 2.

[0046] Specifically, the air pressure shutoff valve 6 includes a pressure gauge 15, which is mounted on and electrically connected to the sensor 14. When the pressure within the pipe becomes excessive, the pressure gauge 15 and sensor 14 work together to accurately detect the pressure change and trigger the pressure shutoff valve 6 to cut off the gas supply from the gas storage tank 1 to the gas pipe network structure 2. This configuration enhances the system's pressure monitoring capabilities and automatic control capabilities, effectively preventing pipeline explosions caused by excessive pressure. The integrated design of the pressure gauge 15 and sensor 14 enables more precise and efficient pressure monitoring and control, effectively improving the safety and reliability of the system.

[0047] In one embodiment, the gas storage tank 1 is made of stainless steel.

[0048] Specifically, gas tank 1 is made of stainless steel, which offers excellent corrosion resistance and strength, effectively resisting the effects of the external environment and the impact of internal pressure, thereby extending the service life and safety of gas tank 1. The use of stainless steel enhances the durability and stability of gas tank 1, reduces safety hazards caused by material degradation, and ensures the long-term stable operation of the gas pipeline system.

[0049] In a specific example, an outer bracket 18 is provided around the outer surface of the gas network pipe structure. One end of the outer bracket 18 is fixedly connected to the gas network pipe structure, and the other end is fixed to the ground.

[0050] Specifically, an external bracket 18 is provided around the outer surface of the gas network structure. One end of the bracket is fixedly connected to the gas network structure, and the other end is anchored to the ground. This design provides additional support and stability, reducing displacement and vibration of the network structure, ensuring stable operation of the system. The provision of the external bracket 18 strengthens the support of the network structure, reduces damage to the network structure caused by vibration or external impact, and further improves the overall safety of the system.

[0051] In a specific example, the manual stop valve 5 includes manual stop valve 5 vents provided at both ends, the manual stop valve 5 vent at one end is connected to the gas storage tank 1, and the manual stop valve 5 vent at the other end is connected to the air pressure stop valve 6.

[0052] Manual shut-off valve 5 features vents at both ends. One end connects to gas storage tank 1, and the other connects to pressure shut-off valve 6. This design allows the user to manually control gas flow when needed. Combined with pressure shut-off valve 6, manual operation can be performed in the event that the automatic control system fails. This design provides an additional control method, improving the system's operational flexibility and emergency response capabilities.

[0053] In a specific example, the air pressure shut-off valve 6 includes air pressure shut-off valve 6 vents provided at both ends, the air pressure shut-off valve 6 vent at one end is connected to the manual shut-off valve 5, and the air pressure shut-off valve 6 vent at the other end is connected to the gas pipe network structure 2.

[0054] Specifically, the air pressure shut-off valve 6 includes vent holes at both ends. One vent hole connects to the manual shut-off valve 5, and the other vent hole connects to the gas pipe network structure 2. This configuration ensures that the air pressure shut-off valve 6 can effectively connect and cooperate with the manual shut-off valve 5 and the pipe network structure, achieving precise control of gas flow. The vent hole design of the air pressure shut-off valve 6 improves the operating efficiency of the air pressure shut-off valve 6 and the safety of the system, ensuring that gas flow remains within the normal pressure range and preventing safety issues caused by abnormal gas pressure.

[0055] In a specific example, a first manual shut-off valve 16 and a first air pressure shut-off valve 17 are provided on the first gas pipeline 8. One end of the first air pressure shut-off valve 17 is connected to the first gas pipeline 8, and the other end is connected to the manual shut-off valve 5. The second manual shut-off valve 22 is connected to the gas storage tank 1.

[0056] Specifically, the first gas pipeline 8 is equipped with a first manual shut-off valve 16 and a first air pressure shut-off valve 17. One end of the first air pressure shut-off valve 17 is connected to the first gas pipeline 8, and the other end is connected to the manual shut-off valve 5. A second manual shut-off valve 22 is connected to the gas tank 1. This configuration enables effective control and management of the first gas pipeline 8, while providing both manual and automatic protection mechanisms. The provision of the manual shut-off valve 5 and the air pressure shut-off valve 6 on the first gas pipeline 8 enhances the system's pressure regulation capabilities and operational flexibility, enabling rapid intervention in the event of an abnormality and improving the safety of the gas pipeline network system.

[0057] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
