[0002] Town gas refers to a system that supplies gaseous fuels to urban residents, industrial and commercial users, etc., through pipelines. It mainly includes natural gas, liquefied petroleum gas (LPG), and manufactured gas.

[0003] In urban gas supply systems, gas pipelines, valves, and other facilities are widely distributed and face numerous safety risks. On the one hand, the inability to cut off overpressure means that gas is continuously delivered to the user end, causing appliances such as stoves and water heaters to operate under overpressure, increasing the risk of deflagration, causing pipeline rupture, resulting in large-scale gas leaks, and even explosions. On the other hand, the inlet and outlet pipes cannot be adjusted and protected at multiple angles, and the rigid connection has no support points. When the pipeline is subjected to external forces, stress is concentrated at the interface, which can easily lead to loosening and rupture of the interface, causing gas leaks. Utility Model Content

An electronic telescopic rod 12 is fixedly connected to the top of the top cover 4. The output end of the electronic telescopic rod 12 extends into the inside of the top cover 4 and is fixedly connected to the top of the pressure cover 10.

[0027] The electronic telescopic rod 12 is connected to a power supply and a control module. The control module controls the length of the electronic telescopic rod 12 according to pressure changes. The specific control method and the specific control module are existing technologies and are not the main technical solutions to be protected in this application. The power supply provides power to the electronic telescopic rod, and the control module has a preset program to ensure that it can control the electronic telescopic rod according to pressure changes.

[0028] In an embodiment of this utility model, in the gas supply of urban residential areas, when gas flows into the gas inlet slot 2 from the gas inlet pipe 19 and the pressure changes, the electronic telescopic rod 12 extends and retracts according to the set program, pushing the pressure cover 10 to adjust the position of the regulating cylinder 8 through the spring 11, so that the sealing plug 9 controls the size of the opening of the through slot 7 to achieve pressure regulation. If the pressure is abnormal, the sealing plug 9 can block the through slot 7 to prevent gas leakage.

[0029] As an optional embodiment, the ends of the air inlet slot 2 and the air outlet slot 3 that are far apart are respectively connected to the air inlet pipe 19 and the air outlet pipe 20 via flanges, and a manual shut-off valve 21 is provided on the outside of the air inlet pipe 19.

[0030] In an embodiment of this utility model, during the maintenance of gas facilities, the staff manually closes the manual shut-off valve 21 on the gas inlet pipe 19 to cut off the gas from entering the pressure regulating valve, ensuring safety during the maintenance process. In daily use, the valve remains open to ensure that gas is delivered normally to the user's home.

[0031] As an optional embodiment, both the intake pipe 19 and the exhaust pipe 20 are provided with a multi-angle adjustable protective mechanism. The multi-angle adjustable protective mechanism includes a lower protective clamp 22, an upper protective clamp 23, a threaded rod 24, an adjusting sleeve 25, and a fixed base 26. The lower protective clamp 22 and the upper protective clamp 23 are used in conjunction with screws to protect the outside of the intake pipe 19 and the exhaust pipe 20. The threaded rod 24 is fixedly connected to the bottom of the lower protective clamp 22. The adjusting sleeve 25 is threadedly connected to the outside of the threaded rod 24. One side of the fixed base 26 is connected to the outside ground or wall, and the other side is rotatably connected to the end of the adjusting sleeve 25 away from the threaded rod 24.

[0032] In this embodiment of the utility model, the height of the threaded rod 24 is changed by rotating the adjusting sleeve 25, so that the air inlet pipe 19 and the air outlet pipe 20 are adjusted to a suitable position. Then, the lower protective clamp 22 and the upper protective clamp 23 are used to fix them. The pipe angle is adjusted by rotating the fixing base 26 to stabilize the protective pipe and prevent damage from external pulling.

[0033] As an optional embodiment, the bottom of the gas pressure regulating valve 1 is threadedly connected to a threaded plug 13, and the bottom of the threaded plug 13 is provided with a bottom groove 14. A filter 15 is provided inside the filter tank 6. The filter 15 is replaced through the threaded plug 13. The bottom groove 14 is a blind groove, which facilitates the installation or removal of the filter. Sealant is provided between the threaded plug 13 and the bottom of the gas pressure regulating valve 1, which is replenished each time it is replaced. The top of the filter abuts against the through groove to ensure that the gas entering the filter tank can be fully filtered.

[0034] In an embodiment of this utility model, after long-term use of gas, the filter 15 becomes dirty due to the interception of impurities. The staff unscrews the threaded plug 13, takes out the old filter 15, puts the new filter 15 into the filter tank 6, and then tightens the threaded plug 13 to ensure that the filter tank 6 is sealed, thereby filtering impurities in the gas and ensuring a clean gas supply.

[0035] As an alternative embodiment, a pressure gauge 16 is fixedly connected to one side of the top of the gas pressure regulating valve 1, and the input end of the pressure gauge 16 extends into the interior of the air inlet slot 2.

[0036] In this embodiment of the utility model, during the gas transmission process, the pressure gauge 16 displays the gas pressure in the gas inlet sump 2 in real time. By observing the value of the pressure gauge 16, the staff can determine whether the working status of the pressure regulating valve is normal. If the pressure rises or falls abnormally, the fault can be investigated in time to ensure the safe and stable gas supply.

[0037] As an alternative embodiment, a protective cover 17 is threaded onto the top of the top cover 4 and located on the outside of the electronic telescopic rod 12.

[0038] In the embodiments of this utility model, in the application scenario of outdoor gas pressure regulating valve 1, the protective cover 17 can prevent rainwater, dust and other substances from entering the interior of the top cover 4, protect the electronic telescopic rod 12 from external corrosion, avoid the normal operation of the pressure regulating valve due to damage to electronic components, and extend the service life of the equipment.

[0039] As an alternative embodiment, a sealing gasket 18 is embedded in the bottom of the top cover 4, and the sealing gasket 18 is in contact with the top of the gas pressure regulating valve 1.

[0040] In the embodiments of this utility model, when installing or repairing the pressure regulating valve, tightening the screws on the top cover 4 causes the sealing gasket 18 to deform under pressure, filling the gap between the top cover 4 and the gas pressure regulating valve 1 to form a seal, preventing gas from leaking from the top and ensuring the overall sealing and safety of the gas pressure regulating valve 1.

[0041] The working principle of this utility model is as follows: When the gas enters the gas inlet slot 2 through the gas inlet pipe 19 during use, the manual shut-off valve 21 controls the inflow of the gas.

[0042] Gas enters the sliding groove 5 from the inlet groove 2, the regulating cylinder 8 slides in the sliding groove 5, and the sealing plug 9 contacts and cooperates with the through groove 7 to regulate the gas flow rate.

[0043] The electronic telescopic rod 12 drives the pressure cover 10 to move up and down, and the spring 11 adjusts the position of the regulating cylinder 8 to ensure stable gas flow.

[0044] Gas enters filter tank 6 through channel 7. Filter 15 filters the gas to remove impurities and particulate matter. The filtered gas is discharged from outlet channel 3 through outlet pipe 20.

[0045] Pressure gauge 16 monitors the gas pressure in the air inlet 2 in real time to ensure the normal operation of gas pressure regulating valve 1;

[0046] The multi-angle adjustable protective mechanism uses the lower protective clamp 22 and the upper protective clamp 23 to protect the air inlet pipe 19 and the air outlet pipe 20, the threaded rod 24 and the adjusting sleeve 25 to adjust the angle of the protective mechanism, and the fixed base 26 to fix the protective mechanism to the ground or wall.

[0047] The threaded plug 13 facilitates the replacement of the filter 15, the protective cover 17 protects the electronic telescopic rod 12, and the sealing gasket 18 ensures the seal between the top cover 4 and the gas pressure regulating valve 1.

[0048] The entire device, through the coordinated operation of the regulating cylinder 8, filter 15, electronic telescopic rod 12, pressure gauge 16, and multi-angle adjustment and protection mechanism, achieves safe management and protection of urban gas, ensuring the stable operation of the gas system.
