Description

A rapid anti-leakage device for oil pipelines

technical field

The utility model relates to an anti-leakage device, in particular to a rapid anti-leakage device for oil pipelines.

Background technique

At present, oil pipelines have become one of the main transportation tools for oil. 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. Oil pipelines mainly include isothermal transportation, heating transportation and sequential transportation. Pipeline corrosion and how to prevent corrosion are one of the important links in pipeline maintenance. However, in the long-term use process, the oil pipeline will inevitably be damaged, resulting in the leakage of crude oil, which has brought a lot of economic losses. This has resulted in the leakage prevention and plugging device of the oil pipeline. The current structure of the oil pipeline leakage prevention and plugging device is not It is convenient for quick installation, and some need bolts and nuts to fix it, which is not conducive to quickly plugging the oil leakage point, and when the leak is plugged, the leaking part is prone to oil leakage again.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a quick oil pipeline leakage prevention device to solve the above existing technical problems.

In order to achieve the above object, the utility model provides a quick anti-leakage device for oil pipelines, which comprises two arc-shaped splints connected together through the rotation of the rotating shaft and two supporting rods symmetrically fixed on one side of the two arc-shaped splints. A fixed rotating plate is respectively fixed on the upper end of the tight strut, and each fixed rotating plate passes through the rotating shaft and is fixed with two movable rotating plates, and the two movable rotating plates on both sides are respectively fixed on the top tightening thread rods The other end of the tightening threaded rod is opposite to and screwed into the inner threaded sleeve respectively, and the left and right threads in the inner threaded sleeve rotate in opposite directions, and the threaded rotation direction of the tightening threaded rods on both sides is also opposite, and the inner threaded sleeve The periphery of the barrel is fixedly connected with a plurality of breaking rods, and the inner surface of each arc-shaped splint is respectively fixed with an arc-shaped inflatable bag, and the inner arc surface of the inflatable bag is fixedly connected with an arc-shaped elastic pressure plate. The inner arc surface is respectively fixedly connected with a layer of rubber sealing plate.

When a certain part of the oil pipeline leaks, block the leaking part with the rubber sealing plate, and then turn the lever to rotate the inner threaded sleeve. Since the left and right threads in the inner threaded sleeve rotate in the opposite The thread rotation direction of the threaded rod is also opposite. When the internal threaded sleeve is turned, the two tightening threaded rods can only move close to each other or move away from each other at the same time. Then the two arc-shaped splints are moved closer to each other to complete the clamping of the oil pipeline, so that the rubber sealing plate blocks the corresponding oil leakage part. The whole process only needs to rotate the lever, which is convenient for quick operation to block the leakage. Oil parts, and the inflatable bag and elastic pressure plate can make the rubber sealing plate fully fit with the outer wall of the oil pipeline, thereby improving the overall plugging and anti-leakage effect.

Detailed ways

As shown in Figure 1 and Figure 2, a quick anti-leakage device for oil pipelines includes two arc-shaped splints 2 that are connected together through the rotation of the rotating shaft 1 and two top braces symmetrically fixed on one side of the two arc-shaped splints 2 Rod 3, a piece of fixed rotating plate 4 is respectively fixed on the upper end of the supporting rod 3, each fixed rotating plate 4 penetrates through the rotating shaft 1 and is fixed with two movable rotating plates 5, and the two movable rotating plates 5 on both sides One end of the top-tightening threaded rod 6 fixed on both sides respectively, the other end of the top-tightening threaded rod 6 is opposite and screwed into the inner threaded sleeve 7 respectively, and the left and right threads in the inner threaded sleeve 7 rotate in the opposite direction. The threaded rotation direction of the top tightening threaded rod 6 is also opposite, and the periphery of the internally threaded sleeve 7 is respectively fixedly connected with a plurality of moving rods 8, and the inner surface of each curved splint 2 is respectively fixed with an arc-shaped air bag 9, which is filled with air. The inner curved surface of the airbag 9 is fixedly connected with an arc-shaped elastic pressure plate 10, and the inner arc surface of the elastic pressure plate 10 is respectively fixedly connected with a layer of rubber sealing plate 11. The elastic pressure plate 10 is made of 55Si2Mn spring steel, and the 55Si2Mn spring steel has High strength, good elastic limit, high yield ratio, and good toughness after heat treatment. When sealing the oil leakage pipe with a bending degree smaller than the elastic pressure plate 10, the elastic pressure plate 10 can expand and tightly press the rubber sealing plate 11 on the oil leakage. On the pipe, and then play a good role of close covering and sealing, when the utility model is not used, the elastic pressure plate 10 can effectively ensure that the inflatable bag 9 fixedly connected with it is also arc-shaped, and plays the role of setting the inflatable bag 9;

The two ends of the elastic pressing plate 10 are processed into arc surfaces through grinding to prevent the edge of the elastic pressing plate 10 from piercing the inflatable bag 9, and the inflatable bag 9 can be made of flexible and well-tight rubber. The cushioning effect, that is, the effect of the air spring, can better protect the oil pipeline and prevent the oil pipeline from being pinched, and the air inside the inflatable bag 9 has extremely strong fluidity, so it can clamp and block the oil leakage part of the oil pipeline. When leaking, it can disperse the internal pressure more evenly, and then disperse the pressure on both sides of the air bag 9. It has good deformation ability, as shown in Figure 2, which can ensure that the elastic pressure plate 10 and the rubber sealing plate 11 are more completely pressed against the oil pipeline leakage. The oil achieves a better sealing effect and more effectively blocks the oil leakage site;

The outer sides of each top tight strut 3 are respectively provided with a triangular reinforcing plate 12 whose top is connected to the fixed rotating plate 4. The triangular reinforcing plate 12 can greatly improve the firmness of the top tight strut 3, and can also improve the fastening of the top tight strut. 3, when the internally threaded sleeve 7 is rotated, the tightening force exerted by the two stretched tightening threaded rods 6 on the tightening strut 3 can better act on the two curved splints 2, It is beneficial to fully ensure the clamping force of the two curved splints 2, thereby more effectively tightening the rubber sealing plate 11 against the oil leakage part of the oil pipeline.

It should be noted that the radians of the curved splint 2 and the elastic pressure plate 10 can be determined according to the diameter of the oil pipeline, and various specifications of the utility model with different specifications can be made for future use.

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples. Those of ordinary skill in the art can make changes, changes, additions or replacements within the essential scope of the present utility model. Should belong to the protection scope of the present utility model.
