[0002] The oil pipeline is composed of oil pipes and their accessories, which are used to complete the tasks of oil loading and unloading and transportation. The pipes of the oil pipeline are generally steel pipes, which are connected into long-distance pipelines using connecting devices such as welding and flanges, and valves are used for opening and closing control and flow regulation.

[0003] The interfaces of oil pipelines are generally flanged, but the interfaces of oil pipelines lack anti-leakage protection structures, resulting in unsatisfactory sealing effects of the oil pipelines and hidden dangers of oil leakage. At present, the oil production pipelines lack effective anti-leakage devices, which makes the oil pipelines have hidden dangers of oil leakage when in use, resulting in certain economic losses. Therefore, the utility model proposes an anti-leakage device for oil production pipelines to solve this problem. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1 and Figure 2 As shown, an oil production pipeline leakage prevention device proposed in an embodiment of the utility model comprises a pipeline 1 and a pipeline 2, wherein a splicing block 1 3 is integrally formed at the end of the pipeline 1, and a splicing block 2 5 is integrally formed at the end of the pipeline 2. The arrangement of the splicing block 1 3 and the splicing block 2 5 facilitates the splicing and assembly between the pipeline 1 and the pipeline 2, and increases the tightness. The splicing block 1 3 and the splicing block 2 5 are both provided with wedge surfaces 4 that match each other. The two wedge surfaces 4 between the pipeline 1 and the pipeline 2 fit each other, and the wedge surfaces 4 can reduce the gap, so that the fit between the pipeline 1 and the pipeline 2 is tighter, and the possibility of oil leakage is reduced. The pipeline 1 is located on one side of the splicing block 1 3, and the pipeline 2 is located on one side of the splicing block 2 5. An annular body 7 is integrally formed, and a connecting flange 8 is arranged on the annular body 7. The arrangement of the connecting flange 8 facilitates the connection and fixation between the pipeline 1 and the pipeline 2. The connecting flange 8 is arranged on the annular body 7 to achieve the fixation of the connecting flange 8.

[0023] like Figure 2 As shown, in some embodiments, the connecting flange 8 at the end of pipeline 1 and the connecting flange 8 at the end of pipeline 2 2 abut against each other, and mounting holes are provided on the connecting flanges 8. The connecting flanges 8 between pipeline 1 1 and pipeline 2 2 abut against each other, and have strong tightness, which can prevent oil leakage and realize the connection and fixation between pipeline 1 1 and pipeline 2 2.

[0024] like Figure 2As shown, in some embodiments, the pipeline 1 is located between the splicing block 1 3 and the annular body 7, and the pipeline 2 is located between the splicing block 2 5 and the annular body 7. The two leak-proof protection grooves 6 are respectively penetrated to the outside of the pipeline 1 and the pipeline 2 2. The leak-proof protection grooves 6 of the pipeline 1 and the pipeline 2 are respectively penetrated to the outside of the pipeline 1 and the pipeline 2. The sealing gasket 9 and the sealing leak-proof ring 10 are arranged. By penetrating the two leak-proof protection grooves 6 to the outside of the pipeline 1 and the pipeline 2, the sealing gasket 9 and the sealing leak-proof ring 10 are facilitated. Assemble, the sealing gasket 9 and the sealing leak-proof ring 10 are distributed from the inside to the outside in the leak-proof protection groove 6, and the sealing performance of this matching method is good; it should be noted that by opening the leak-proof protection groove 6 on both the pipeline 1 1 and the pipeline 2 2, and arranging the sealing gasket 9 and the sealing leak-proof ring 10 at the leak-proof protection groove 6, the sealing gasket 9 and the sealing leak-proof ring 10 are distributed from the inside to the outside in the leak-proof protection groove 6, which can increase the tightness of the matching between the pipeline 1 1 and the pipeline 2 2, reduce the seepage of oil in the gap, and form a good leak-proof protection effect.

[0025] like Figure 2 As shown, in some embodiments, a protrusion is formed at the end of the splicing block 1 3, and the protrusion is adapted to the groove correspondingly opened in the splicing block 2 5; it should be noted that by providing a protrusion at the end of the splicing block 1 3, the setting of the protrusion and the groove can further increase the tight fitting effect between the splicing block 1 3 and the splicing block 2 5, and facilitate the bite connection between the splicing block 1 3 and the splicing block 2 5.

[0026] like Figure 2 As shown, in some embodiments, the annular body 7 and the connecting flange 8 are integrally formed, and the connecting flange 8 is integrally formed on the annular body 7, which has good stability.

[0027] The working principle and use steps of the utility model are as follows: before connecting the pipeline 1 and the pipeline 2, a sealing gasket 9 is placed in the leakproof protection groove 6 of the pipeline 1 or the pipeline 2, and then the sealing leakproof ring 10 is adapted to the outer side of the sealing gasket 9 to achieve the adaptation of the sealing gasket 9 and the sealing leakproof ring 10 at the leakproof protection groove 6, and then the end portions of the pipeline 1 and the pipeline 2 are spliced, so that the splicing block 1 3 is connected to the splicing block 2 5, and the wedge-shaped surfaces 4 between the splicing block 1 3 and the splicing block 2 5 are bite-fitted, so that the sealing gasket 9 and the sealing leakproof ring 10 extend to the other leakproof protection groove 6, and then the pipeline 1 and the pipeline 2 are connected and fixed through the connecting flange 8 between the pipeline 1 and the pipeline 2. When the oil pipeline is actually used, the connection gap can be reduced by the wedge-shaped surface 4 between the splicing block 1 3 and the splicing block 2 5 to prevent oil from seeping out. At the same time, a sealing gasket 9 and a sealing leakproof ring 10 are also arranged at the gap between the pipeline 1 and the pipeline 2 to further increase the leakproof protection effect and prevent oil from leaking out.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
