The invention discloses a self-checking and self-repairing anti-leakage oil pipeline, which belongs to the field of oil pipelines. The invention uses an oil-absorbing trigger beam to absorb leaked oil to cause self-expansion and deformation, and then punctures an annular water bag to allow water to flow out, and the compound expansion layer When it encounters water, it expands inwardly, driving the repair arc plate to move closer to the oil pipeline, and the repair arc plate gradually fits the outer surface of the oil pipeline. broken, the internal pipeline repair agent flows out and fills between the repair arc plate and the oil pipeline, and enters the leakage point for deep repair. At the same time, the repair arc plate is fixed and sealed on the oil pipeline by the cured pipeline repair agent The outer surface further realizes the sealing of the leakage point and the outside of the oil pipeline. In addition, after the outer tube of the discoloration measuring point contacts with water, a color mark gradually appears on the outer surface, realizing the automatic positioning and detection of the pipeline leakage point.
Description
technical field [0001] The invention relates to the field of oil pipelines, in particular to a self-checking and self-repairing anti-leakage oil pipeline. Background technique [0002] With the rapid development of today's society, energy is an indispensable resource. Petroleum is a kind of naturally stored energy. The exploitation of petroleum requires drilling to extract oil, petroleum smelting, and then transporting it to various sites for use. The transportation of oil is carried out through oil pipelines, and each oil pipeline forms a transmission network to transport oil to various places where it is needed. The pipes of oil pipelines are generally steel pipes, which are connected to long-distance pipelines by welding and flange connection devices, and valves are used for opening and closing control and flow regulation. [0003] During the actual use of oil pipelines, due to material corrosion or other factors, cracks in the pipelines are likely to cause oil leakage,...
