[0002] With the development of economy and the acceleration of industrialization, the consumption of oil products is also increasing rapidly. Oil products are highly volatile, and a large amount of oil and gas will inevitably evaporate during the loading and unloading process, and the accompanying oil and gas pollution problem is becoming increasingly serious. According to statistics, tens of tons of oil and gas are discharged into the atmosphere every year. On the one hand, this leads to a large amount of waste of oil and gas resources and reduces the economic benefits of enterprises. On the other hand, it leads to serious environmental pollution, endangering the safe production of enterprises and directly affecting the health of operators and people in the surrounding environment. Therefore, in the process of oil loading, oil and gas recovery and treatment are particularly important, and sealing oil and gas recovery is a very important link.

[0003] During the installation and disassembly of oil products, pipelines are used to transport oil products. However, the most common pipeline connection method currently adopts direct flange connection. This connection method has poor sealing performance and is prone to leakage at the connection point, leading to safety accidents. Utility Model Content

However, the common pipeline connection method currently mostly adopts direct connection with flanges, which has poor sealing performance and is prone to leakage at the connection parts, leading to the problem of safety accidents.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pipeline connection structure for an oil and gas recovery device comprises a pipeline connector and butt pipes arranged at both ends of the pipeline connector, the pipeline connector comprises a connecting ring, fastening pipes are symmetrically arranged on both sides of the connecting ring, the diameter of the fastening pipes gradually decreases from one end close to the connecting ring to the end away from the connecting ring, a sealing ring is coaxially arranged at one end of the fastening pipe close to the connecting ring, a plurality of evenly distributed sliding grooves are opened on the fastening pipe outside the sealing ring, a sliding rod is slidably connected in the sliding groove, a stop plate located in the sliding groove is arranged at one end of the sliding rod, and the other end of the sliding rod extends to the outside of the sliding groove and is fixedly connected to the connecting ring.

[0007] As a preferred technical solution of the utility model, a tension spring is sleeved on the outer side of the slide rod between the connecting ring and the fastening tube.

[0008] In order to ensure the sealing effect of the connection between the pipeline connector and the butt pipe, sealing grooves for the sealing retaining ring to be inserted are provided on the end surfaces on both sides of the connecting ring.

[0009] In order to further improve the sealing effect of the connection between the pipeline connector and the butt pipe, a plurality of sealing rings are installed on the inner wall of the sealing retaining ring and the outer wall of the sealing retaining ring.

When the guide column is plugged into the bottom of the guide groove, the sealing retaining ring on the fastening tube is plugged into the bottom of the sealing groove. During the plugging process, the fastening tube continuously squeezes the stretching spring for compression, so that the outer wall of the fastening tube is tightly fitted with the inner side surface of the limiting sealing ring in the docking tube, thereby avoiding leakage at the connection part of the docking tube and the pipe connecting piece, which leads to safety accidents and greatly improves the sealing and safety of the connection between the docking tube and the pipe connecting piece. Finally, the connecting bolt is inserted into the connected first connecting hole and the second connecting hole for fixing, and the installation is completed. BRIEF DESCRIPTION OF THE DRAWINGS
