Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe explosion prevention, in particular to an explosion-proof safety structure of a high-pressure oil pipe. Background Art

[0002] High-pressure oil pipes are components of high-pressure oil circuits. They are required to withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. Therefore, during the use of high-pressure oil pipes, the material of the oil pipes is selected and restricted so that the oil pipes can withstand greater pressure.

[0003] In actual work, the structure and function of the explosion-proof safety structure of the high-pressure oil pipe in the existing technology are relatively complete and can basically meet the needs of daily use, but there are still the following problems:

[0004] During use, the oil pipe will deform under the action of internal high pressure. This deformation process is safe in the short term and is within the tolerance range of the oil pipe material. After long-term use, the safety performance will be reduced due to aging of the material. At this time, it is very easy to cause the pipe to burst, and the broken parts of the oil pipe will splash, causing personal injury. In the case of excessive pressure, the pipe will also burst, which will cause hidden dangers.

[0005] Therefore, the utility model provides a high-pressure oil pipe anti-burst safety structure. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, this embodiment provides a technical solution: an explosion-proof safety structure for a high-pressure oil pipe, comprising two pipe bodies 1, an explosion-proof safety structure 2 is arranged between the two pipe bodies 1; a disassembly and assembly protection structure 3 is arranged between the two explosion-proof safety structures 2; the explosion-proof safety structure 2 comprises two connectors 21, one side of the outer surface of the connector 21 is fixedly connected to one side of the outer surface of the pipe body 1, one side of the outer surface of the connector 21 is fixedly connected to a first annular sleeve 22, one side of the outer surface of the first annular sleeve 22 is fixedly connected to a protection net 23, and the outer surface of the protection net 23 is fixedly connected to a side away from the first annular sleeve 22. By setting the explosion-proof safety structure 2, the protection net 23 cooperates with the first annular sleeve 24. Under the action of an annular sleeve 22 and a second annular sleeve 24, the outer surface of the tube body 1 can be assisted in protection, and then, under the action of the auxiliary cylinder 26 and the circular through hole 25, in cooperation with the sliding rod 28, the buffer spring 210, the connecting plate 29, the connecting rod 211 and the piston block 212 and other components, the high pressure inside the tube body 1 can be assisted in pressure relief operation.

One end of the outer surface of the second threaded clamping rod 39 is fixedly connected to a protective rod 310. Under the action of the round insertion rod 35, it can cooperate with the first threaded clamping rod 37 and the fixed screw hole tube 38, and then cooperate with the second threaded clamping rod 39 to disassemble and assemble components such as the protective rod 310, so that components such as the protective rod 310 can play an auxiliary protective role.
