[0002] Gas pipelines are tubular systems specifically designed for transporting various types of gases. They are widely used in energy, industry, municipal, medical and other fields. Their core function is to safely and efficiently transport gases from production sources, storage facilities or processing centers to end users or application scenarios through pipeline networks, meeting the gas supply needs of different industries.

[0003] In some industrial gas transmission pipelines, it is often necessary to ensure the stability of the transmitted gas. In actual transmission, gas instability can easily occur, which can have negative effects in some industrial processes that require pressure stabilization. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a gas pipeline pressure reducing and stabilizing device, addressing the shortcomings mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a gas pipeline pressure reducing and stabilizing device, including an inlet pipeline and a stable delivery pipeline, with a first pressure sensor and a second pressure sensor installed before and after the stable delivery pipeline, and a pressure stabilizing pipeline installed between the inlet pipeline and the stable delivery pipeline.

The pressure relief pipeline is provided with a first flow control valve and a first check valve, and the pressure boosting pipeline is provided with a second flow control valve and a second check valve.

[0007] Furthermore, a booster pump is provided at the end of the booster pipe, and the booster pump is provided with an air supply pipe to facilitate booster operation.

[0008] Furthermore, the pressure relief pipe is equipped with a gas collection device at its end, and the pressure relief pipe extends into the gas collection device where a gas collection tank structure is provided to facilitate pressure relief and storage operations.

[0009] Furthermore, the gas collection tank structure is equipped with a pressure sensor at the top and an exhaust pipe at the bottom, with an exhaust pump on the exhaust pipe to facilitate the discharge operation after depressurization and storage.

[0010] Furthermore, the intake pipe is equipped with a filter structure to facilitate the filtration of intake substances.

[0011] Furthermore, the pressure-stabilizing pipeline is equipped with a pressure-stabilizing orifice plate, which can be used for gas stabilization operations.

[0012] The advantages of this gas pipeline pressure reducing and stabilizing device compared with the prior art are as follows: This device sets up a pressure relief pipe and a pressure boosting pipe through a pressure stabilizing pipe, which can timely boost and reduce pressure when the air intake of the front-end air intake pipe is unstable, thereby achieving pressure stabilization.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-3 A gas pipeline pressure reducing and stabilizing device includes an inlet pipeline 1 and a stable delivery pipeline 3. A first pressure sensor 12 and a second pressure sensor 13 are provided at the front and rear of the stable delivery pipeline 3. A pressure stabilizing pipeline 2 is provided between the inlet pipeline 1 and the stable delivery pipeline 3.

[0019] The pressure stabilizing pipeline 2 is provided with a booster pipeline 5 and a pressure relief pipeline 4 at the top and bottom, respectively. The pressure relief pipeline 4 is provided with a first flow control valve 8 and a first check valve 9. The booster pipeline 5 is provided with a booster pump 6 at the end. The booster pump 6 is provided with a gas replenishment pipeline 7. That is, the pressure values ​​at both ends of the stable delivery pipeline 3 are sensed by the first pressure sensor 12 and the second pressure sensor 13 respectively. When the pressure values ​​at both ends are the same, it indicates that the internal gas is stable. When the pressure value of the front pressure sensor is much lower than the value of the rear pressure sensor, it indicates that the delivery pressure is unstable. The booster pump 6 and the first flow control valve 8 are started to replenish gas to achieve pressure stabilization.

[0020] The pressurization pipeline 5 is equipped with a second flow control valve 10 and a second check valve 11. When the pressure value of the front pressure sensor is much lower than that of the rear pressure sensor, it indicates that the delivery pressure is unstable. The second flow control valve 10 is activated to release the pressure and achieve pressure stabilization.

[0021] The pressure relief pipe 4 is equipped with a gas collection device 16 at its end. The pressure relief pipe 4 extends into the gas collection device 16 and is equipped with a gas collection tank structure 17. The top of the gas collection tank structure 17 is equipped with a pressure sensor 20, and the bottom of the gas collection tank structure 17 is equipped with an exhaust pipe 18. An exhaust pump 19 is installed on the exhaust pipe 18. When the value of the gas being transported is high or it cannot be discharged at will, the gas collection device 16 is installed to collect the leaked gas and periodically discharge it through the exhaust pump 19. The exhaust pump 19 needs to be equipped with a corresponding electrically controlled valve to ensure a daily sealing state.

[0022] The air intake pipe 1 is equipped with a filter structure 14, which can prevent excessive impurities from entering. The pressure stabilizing pipe 2 is equipped with a pressure stabilizing orifice plate 15, which can ensure stable gas delivery.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
