Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe plugging, and particularly relates to an extrusion type clamping plugging device. Background Art

[0002] The transportation of oil is an important link in today's oil economy, and the safe transportation of long-distance pipelines is the key to this link. Therefore, it is particularly important to ensure the safe operation of the entire pipeline. The patrol line personnel play an extremely important role in the daily safety management of the pipeline. They are the first "executors" to discover and control potential hazards in the line, equivalent to the eyes of a person.

[0003] As a pressure-bearing pipeline, poor corrosion resistance is a relatively common problem in oil pipelines. After long-term use, oil leakage problems will occur. At the same time, the welded joints between the oil pipeline and the line cleaning riser are prone to weld cracking and oil leakage over the years.

[0004] Patrol line personnel often encounter the phenomenon that the welded joints between the oil pipeline and the line cleaning riser are prone to weld cracking and crude oil leakage. For safety reasons at the scene, welding is strictly prohibited, and welding operations cannot be carried out. Patrol line personnel cannot effectively plug the leak.

[0005] Therefore, the existing technology still needs to be improved. Summary of the Invention

[0006] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide an extrusion type clamping plugging device, aiming to solve the problem of ineffective plugging of the welded joints between the oil pipeline and the line cleaning riser.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] In a first aspect, an extrusion type clamping plugging device includes an oil pipeline, a line cleaning riser is welded on the oil pipeline, and further includes:

[0009] A fixing component, sleeved outside the oil pipeline and located on both sides of the line cleaning riser;

[0010] A plurality of fixing bolts, spaced on the fixing component and arranged in a through manner with the line cleaning riser;

[0011] A tubular pressing sleeve, sleeved outside the line cleaning riser, tightly fitted with the oil pipeline, and an accommodation cavity is provided at the contact with the oil pipeline;

[0012] Sealing filler, filled in the accommodation cavity;

[0013] A pressing plate, fixed on the tubular pressing sleeve through the fixing bolt;

[0014] A fixing nut, screwed on the fixing bolt to fix the pressing plate.

[0015] Further, the fixing component is a fixed clamp, and the fixed clamp is sleeved on the oil pipeline and symmetrically arranged on both sides of the pipeline sweeping riser.

[0016] Further, the fixed clamp is composed of two semi-circular clamps, and the two semi-circular clamps are tightened and fixed by set bolts and set nuts.

[0017] Further, the sealing packing uses graphene packing, and the graphene packing is wound around the welded joint of the oil pipeline and the pipeline sweeping riser.

[0018] Further, a plurality of U-shaped grooves are provided on the pressing plate.

[0019] Further, the tubular pressing sleeve is divided into left and right parts, and the left and right parts are connected by bolts.

[0020] The technical solution adopted by the present utility model has the following beneficial effects:

[0021] In this application, for the problem that the leakage point cannot be welded, we use a fixed clamp to build a fixed support in combination with the external structure of the device, and press the sealing packing to the welded seam through a tubular pressing sleeve, without secondary welding, avoiding the explosion phenomenon. At the same time, using the mechanical extrusion principle and adopting a non-welding method to deal with the leakage point is efficient and rapid; this device has the advantages of low cost and rapid and efficient treatment of leakage points, and is especially suitable for on-site emergency and rescue operations.

[0026] To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] In an embodiment of the present utility model, referring to Figure 1 and Figure 2 , an extrusion type clamping and leak plugging device includes an oil transmission pipeline 1, a purging riser 2 is welded on the oil transmission pipeline 1, a fixing assembly is sleeved outside the oil transmission pipeline 1 and is located on both sides of the purging riser 2; a plurality of fixing bolts 4 are spaced on the fixing assembly and are arranged in a through manner with the purging riser 2; a tubular pressing sleeve 6 is sleeved outside the purging riser 2 and is in close fit with the oil transmission pipeline 1, and an accommodation cavity is provided at the contact position with the oil transmission pipeline 1; a sealing filler is filled in the accommodation cavity; a pressing plate 7 is fixed on the tubular pressing sleeve 6 through the fixing bolts 4; a fixing nut 8 is screwed on the fixing bolts 4 to fix the pressing plate 7.

[0028] During use, a fixed support is built by using the fixing assembly on the external structure of the oil transmission pipeline 1 device. The sealing filler is pressed tightly to the welded seam through the tubular pressing sleeve 6, and the tubular pressing sleeve 6 is compacted and fixed through the pressing plate 7, further preventing leakage at the welded seam. At the same time, the mechanical extrusion principle is utilized and the leak point is treated in a non-welding manner, which is efficient and rapid.

[0029] Among them, it should be noted that in this embodiment, referring to Figure 3 , the sealing filler adopts a graphene packing 5. During use, the graphene packing 5 is wound around the welded joint of the oil transmission pipeline 1 and the purging riser 2, and then compacted through the tubular pressing sleeve 6. The graphene packing 5 is composed of various reinforcing fibers and metal wires wound together, has the property of high temperature resistance, is suitable for sealing operations under high temperature conditions, and can achieve a better plugging effect to avoid leakage.

[0030] In this embodiment, referring to Figure 1 and Figure 2 , the fixing assembly is a fixed clamp 3. The fixed clamp 3 is sleeved on the oil transmission pipeline 1 and is symmetrically arranged on both sides of the purging riser 2. Among them, the fixed clamp 3 is composed of 2 semi-circular clamps, and the 2 semi-circular clamps are tightened and fixed through set bolts and set nuts.

[0031] In this embodiment, referring to Figure 1 , a plurality of U-shaped grooves are provided on the pressing plate 7, so that the pressing plate 7 can be inserted from the side to the purging riser 2 and the fixing bolts 4, which is more convenient.

[0032] In this embodiment, referring to Figure 1 and Figure 2 , the tubular pressing sleeve 6 is divided into left and right parts, and the left and right parts are connected by bolts, which is convenient for fixing to the welded joint of the purging riser 2 and the oil transmission pipeline 1.

[0033] Specifically, when the present utility model is specifically implemented, it includes the following steps:

[0034] First, fix the fixed pipe clamp 3 on both sides of the purging riser 2 where the leak occurs. Secondly, wrap the graphene packing 5 around the leak point. Then, press on the bush and the pressing plate 7 in sequence. Finally, use a wrench to tighten the two nuts on the pressing plate 7. Observe the position of the leak point. If there is no liquid leakage, the leak stoppage is successful.

[0035] The technical solution adopted by the present utility model has the following beneficial effects during use:

[0036] 1. Welding-free: Leak stoppage is achieved by using the mechanical extrusion principle, which is especially suitable for on-site emergency and rescue operations, greatly solving on-site problems.
