Description

Technical Field

[0001] This utility model relates to the field of oil connection pipeline technology, and in particular to an oil wellhead pipeline connector. Background Technology

[0002] Oil extracted from oil wells needs to be transported through external oil pipelines. Traditional oil pipelines are directly connected to the wellhead pipeline. Because the oil extracted directly from the wellhead pipeline has a large impact force, it will have a large impact on the inside of the oil pipeline, causing severe wear and tear on the oil pipeline and significantly reducing the service life of the oil pipeline.

[0003] Existing oil pipelines are prone to internal oil ejection during pumping. Therefore, to address the problem that current wellhead oil pumping and transportation pipelines cannot effectively reduce pressure on the oil, this invention provides an oil wellhead pipeline connector. Utility Model Content

[0004] The purpose of this application is to provide an oil wellhead pipe connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an oil wellhead pipeline connector, comprising a connecting pipe, with pressure-reducing pipes on both sides of the connecting pipe, the top and bottom ends of each pressure-reducing pipe communicating with the connecting pipe, a fixing sleeve inside each pressure-reducing pipe, transmission plates symmetrically arranged on the outer side of each fixing sleeve, each transmission plate being fixedly connected to the fixing sleeve, a sealing block symmetrically arranged on one side of each transmission plate, one side of each sealing block being fixedly connected to the transmission plate, the outer side of each sealing block being inserted into the inner wall of the pressure-reducing pipe, a movable rod penetrating the pressure-reducing pipe being fixedly connected to each fixing sleeve, a protective plate being fixedly connected to one end of each movable rod, an installation plate being fixedly connected to the other end of each movable rod, a buffer spring being fixedly connected to one side of each installation plate, and one end of each buffer spring contacting the inner wall of the connecting pipe.

[0006] Preferably, a blowout shield is fixedly connected to one side of each of the mounting plates.

[0007] Preferably, a fixed cylinder is fixedly connected to one side of each pressure-reducing pipe, and a leak-proof cotton sleeve is provided inside each fixed cylinder. The outer side of each movable rod is slidably connected to the inner wall of the right port of the fixed cylinder.

[0008] Preferably, the outer side of each of the movable rods is slidably connected to the inner side of the leak-proof cotton sleeve.

[0009] Preferably, each of the movable rods is slidably connected to the connecting tube.

[0010] Preferably, the two blowout preventers are arranged symmetrically.

[0011] Preferably, the outer side of each of the transmission plates is slidably connected to the inner wall of the pressure reducing pipe.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This invention, by incorporating a blowout preventer, avoids direct oil extraction, allowing oil to enter the bottom of the pressure-reducing pipeline. The oil compresses the sealing block, which in turn pushes the transmission plate. The transmission plate drives the fixed sleeve, which in turn moves the movable rod. The movable rod then moves the mounting plate, which in turn compresses the buffer spring, allowing oil to flow through the pressure-reducing pipeline. This controls the oil extraction speed, prevents blowouts, and improves the safety of on-site operations. Attached Figure Description

[0022] Example: Reference Figure 1-2The diagram illustrates an oil wellhead pipe connector comprising a connecting pipe 1, with pressure-reducing pipes 6 on both sides of the connecting pipe 1. The top and bottom ends of each pressure-reducing pipe 6 are connected to the connecting pipe 1. Each pressure-reducing pipe 6 has a fixing sleeve 11 inside, and transmission plates 5 are symmetrically arranged on the outer side of each fixing sleeve 11. Each transmission plate 5 is fixedly connected to the fixing sleeve 11. A sealing block 4 is symmetrically arranged on one side of each transmission plate 5, and one side of each sealing block 4 is fixedly connected to the transmission plate 5. The outer side of each sealing block 4 is inserted into the inner wall of the pressure-reducing pipe 6. A movable rod 7 penetrating the pressure-reducing pipe 6 is fixedly connected to each fixing sleeve 11. A protective plate 9 is fixedly connected to one end of each movable rod 7, and an mounting plate 3 is fixedly connected to the other end of each movable rod 7. A buffer spring 2 is fixedly connected to one side of each mounting plate 3, and one end of each buffer spring 2 contacts the inner wall of the connecting pipe 1. This novel structure is reasonable, effectively extending the service life of the device and reducing oil spills.

[0023] With the above structure, a blowout preventer 12 is fixedly connected to one side of each of the mounting plates 3, and the blowout preventer 12 prevents oil and the gas in the oil from being directly extracted.

[0024] With the above structure: a fixed cylinder 10 is fixedly connected to one side of each pressure reducing pipe 6, a leak-proof cotton sleeve 8 is provided inside each fixed cylinder 10, and the outer side of each movable rod 7 is slidably connected to the inner wall of the right port of the fixed cylinder 10. The leak-proof cotton sleeve 8 prevents some oil from leaking from the pressure reducing pipe 6.

[0025] With the above structure, the outer side of each of the movable rods 7 is slidably connected to the inner side of the leak-proof cotton sleeve 8.

[0026] With the above structure, each of the movable rods 7 is slidably connected to the connecting tube 1.

[0027] With the above structure, the two blowout preventers 12 are arranged symmetrically.

[0028] With the above structure, the outer side of each of the transmission plates 5 is slidably connected to the inner wall of the pressure reducing pipe 6.

[0029] The working principle of this embodiment is as follows: When in use, the device is threadedly connected to the wellhead pipeline. The blowout preventer 12 installed inside the device prevents oil from being directly extracted and disperses the internal gas and oil, reducing the possibility of a blowout. This allows the oil to enter the bottom of the pressure reducing pipeline 6. The oil squeezes the sealing block 4, which pushes the transmission plate 5. The transmission plate 5 drives the fixed sleeve 11, which in turn drives the movable rod 7 to move. The movable rod 7 then drives the mounting plate 3 to move, which in turn squeezes the buffer spring 2, allowing oil to flow through the inside of the pressure reducing pipeline 6 and controlling the oil extraction speed.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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 still 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.
