[0002] When gas lift is used in natural gas extraction, a natural gas gas lift safety protection device is often used. This device injects gas into the liquid to form bubbles and increase the density of the liquid, thereby effectively pumping the liquid to the surface. This process improves the efficiency of extraction.

[0003] Natural gas lift safety protection devices typically consist of a control panel, gas delivery valve, and fire prevention device. When the monitoring system detects an abnormal situation, such as excessive pressure or gas leakage, the control panel can quickly trigger the fire prevention device and emergency shutdown mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a natural gas lift safety protection device, including a base plate 1. A connecting assembly for connection is fixedly connected to the top of the base plate 1. The connecting assembly includes an oil pump 2, which is responsible for effectively capturing and guiding natural gas to ensure its stable and safe transmission throughout the process. The outside of the oil pump 2 is fixedly connected to the top of the base plate 1. A sleeve 7 is fixedly connected to the bottom of the oil pump 2. The outside of the sleeve 7 is outside the inner tube 8 and has good pressure resistance to withstand the pressure of the transmitted gas. A gas delivery assembly for conveying gas is fixedly connected to the outside of the connecting assembly. The gas delivery assembly includes a gas storage tank 6 to ensure the safety of gas storage. The outside of the gas storage tank 6 is fixedly connected to the top of the base plate 1. A gas pump 5 is fixedly connected to the front side of the outside of the gas storage tank 6 to quickly increase the gas pressure. The output end of the gas pump 5 is fixedly connected to the outside of a temperature control assembly. A temperature control assembly for controlling the gas temperature is fixedly connected to the outside of the gas delivery assembly. The temperature control assembly includes a condenser 3 for heating or cooling the gas in the pipeline to meet specific working requirements.

[0033] The condenser 3 is externally fixedly connected to the top of the base plate 1. A gas delivery pipe 4 is also externally fixedly connected to the condenser 3 to deliver pressurized gas. The gas delivery pipe 4 is externally fixedly connected to the output end of the gas pump 5. An inner tube 8 is internally fixedly connected to the connecting assembly for discharging liquid. A gas delivery valve 9 is externally fixedly connected to the inner tube 8. The gas delivery valve 9 is designed to precisely control the gas flow and pressure, ensuring gas delivery within a safe range. Sealing plates 10 are fixedly connected to both the left and right sides of the gas delivery valve 9 to prevent gas leakage and ensure the safety of the device. Two support plates 11 are fixedly connected to the front of the gas delivery valve 9 to ensure the stability of the support structure. Multiple return springs 12 are fixedly connected to the outside of the two support plates 11, allowing for rapid return after being subjected to force. The recovery and reset spring 12 is externally fixedly connected to two support frames 13, which reduces the overall weight of the device. The two support frames 13 are externally slidably connected to the outside of the gas supply valve 9. The curved panel 14 is internally fixedly connected to the two support frames 13. The curved panel 14 is designed in an arc shape to provide a better streamlined effect and reduce the resistance when the gas flows. The toggle block 16 is fixedly connected to the front of the two support frames 13, which can toggle the outside of the gas supply valve 9 to prevent blockage. The front of the gas supply valve 9 is provided with multiple gas supply holes 15 for outputting gas. The outside of the multiple gas supply holes 15 is inside the inner tube 8. The outside of the curved panel 14 is arc-shaped, and its curved surface is outside the gas supply holes 15. The gas output through the gas supply holes 15 can be better opened by force.

[0034] Reference Figure 1 and Figure 4The oil pump 2 is externally fixedly connected to a connecting ring 2 18, and externally slidably connected to a connecting ring 1 17. This sliding connection design allows connecting ring 1 17 to move flexibly on connecting ring 2 18, adapting to different working positions and installation requirements. The external surfaces of connecting ring 2 18 and connecting ring 1 17 are on the top of the base plate 1. Both connecting ring 2 18 and connecting ring 1 17 are internally fixedly connected to sealing rings 20, effectively preventing gas leakage, enhancing overall sealing, and ensuring the safety of gas transmission. The top of connecting ring 2 18 is fixedly... The fixed connection has multiple through blocks 19, which can improve the stability and force distribution of the entire device through multi-directional layout, so that the interaction between the components is more uniform when under pressure. Multiple through slots 22 are opened on the outside of the connecting ring 17. The through slots 22 are designed as long strip slots to facilitate the insertion and fixing of the through blocks 19, ensuring a reliable connection between the two connecting rings. Nuts 21 are threaded on the outside of the through slots 22 to ensure that they are not easy to loosen or fall off during operation. The external threads of the nut 21 are connected to the outside of the through blocks 19 and the connecting ring 17.

[0035] Working Principle: First, when the unit starts up, the oil pump 2 is responsible for effectively capturing and guiding the incoming natural gas. Since the oil pump 2 is fixedly connected to the top of the base plate 1 and the bottom is connected to the casing 7, the casing 7 forms a robust foundation capable of withstanding the pressure generated during gas transportation. The gas enters the inner tube 8 through the casing 7, ensuring unobstructed gas flow. As the gas is transported, the gas storage tank 6 stores a large amount of gas, ensuring rapid release when needed. The gas pump 5 is connected to the gas storage tank 6 and functions to increase the gas pressure to meet operational requirements. The pressurized gas output from the gas pump 5 is heated or cooled by the condenser 3, i.e., the temperature control component, to ensure the gas is transported at a suitable temperature. The gas processed by the condenser 3 is transported to the subsequent system through the gas delivery pipe 4. Inside the inner tube 8, the gas is transported to the section with the gas delivery valve 9. The gas delivery valve 9 precisely controls the flow rate and pressure of the gas, ensuring safe gas transportation to avoid any potential leakage or explosion risks. The sealing plates 10 on both sides of the gas valve 9 effectively prevent gas leakage, further enhancing the system's safety. The gas valve 9 is externally connected to a support plate 11, providing structural stability, and an external return spring 12 ensures that the valve quickly returns to its original position after being subjected to force, thus achieving precise control of gas flow. Therefore, the design of the two support frames 13 not only reduces the overall weight of the device but also provides flexible support. When gas flows to the gas outlet 15, the multiple internal gas outlets 15 enable smooth gas release, while the curved design of the curved panel 14 provides a streamlined effect, reducing gas flow resistance. During operation, the design of the actuating block 16 ensures that any blockages are promptly removed, thereby maintaining smooth gas flow.

[0036] During gas transmission, the sealing rings 20 inside connecting ring 2 (18) and connecting ring 1 (17) play a crucial role in effectively preventing gas leakage, improving overall sealing performance, and ensuring the safe passage of gas through each component. Gas flows smoothly through the top of connecting ring 2 (18) and into the connected structure, which contains multiple insertion blocks 19. These blocks, distributed on the top of connecting ring 2 (18), enhance the stability of the entire device under gas pressure and ensure more uniform interaction between components. Connecting ring 1 (17) has multiple slots 22 on its exterior. These elongated slots facilitate the insertion and fixation of the insertion blocks 19, ensuring a reliable connection between the two connecting rings and preventing loosening or detachment during operation. Nuts 21 connect to the slots 22 via external threads, further reinforcing the connection between connecting ring 1 (17) and the insertion blocks 19 to withstand the impact of gas pressure.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
