Description
Technical Field
The invention relates to the field of pipeline sealing, in particular to a magnetic force guide bi-component adhesive pipeline leakage sealing device.
Background
The AB glue is a different name of two-liquid mixed hardening glue, and the AB glue is called a bi-component adhesive. The AB glue can be mixed to realize the bonding performance. The AB glue can be used for strong bonding of metal, plastic, ceramic, glass, wood, stone, hardware, ABS, magnet, acrylic, stainless steel and iron.
The destruction of pipes can be broadly divided into three categories: the first type is a small local failure, such as a small hole or a small crack leak. Such leaks are often caused by localized corrosion or weld defects. The second type is localized destruction, requiring protective sheathing on the outside of the steel pipe or replacement of the destroyed section with a short pipe. Such damage is most common, such as a boat anchor hook. The third category is the large-scale damage that occurs on relatively long pipe sections, resulting in a significant reduction in the axial strength of the pipe. This situation requires the replacement of the damaged portion with a long tube segment.
Local leaks in pipes due to local corrosion or weld defects are the most common failure modes. For such failure modes, the following solutions are proposed in the prior art:
for example, chinese patent CN108458202A discloses a natural gas pipeline leakage stopping device, which comprises a clamping frame and two sets of leakage stopping mechanisms symmetrically arranged on the clamping frame, wherein the leakage stopping mechanisms comprise adjusting screws, positioning rods, and leakage stopping plates, and further comprises a gauze and a rubber tube filled with sealant, the gauze is arranged on a gasket, the gauze is located between the gasket and the pipeline, the gasket is provided with a through hole communicated with the gauze, the rubber tube is arranged on a pressing plate, a glue outlet of the rubber tube is connected with the through hole, when stopping leakage, the sealant in the rubber tube enters the gauze through the through hole, and the infiltrated gauze blocks leakage points; the invention can improve the sealing performance and prevent a small amount of leakage; the service life of the pipeline after plugging is prolonged, and the cost is saved.
If chinese patent No. 200720097226.3 discloses a pipeline U type leaking stoppage card in 2008, 7/30, its technical scheme does pipeline U type leaking stoppage card is by arc steel sheet and the annular connector of U type linking arm lock, the arc steel sheet both ends are equipped with the engaging lug, and the engaging lug is equipped with the bolt via hole, and it has the rubber slab for leaking stoppage to inlay in the arc steel sheet, U type linking arm both ends are equipped with the screw thread. However, in the actual use process, a special tool is needed to fix the plugging card on the pipeline, and the defects of long plugging time and inconvenience in plugging exist.
The self-protection pressure leakage stopping device is disclosed in 2015, 2 and 18 days as the Chinese patent No. 201410598602.1, and the technical scheme is that the pressure leakage stopping device comprises a clamp, a leakage stopping plate and a chain, wherein the clamp hoops the leakage stopping plate on a pipeline through the chain, the clamp tightens the chain by using a lead screw structure, and the leakage stopping plate reduces the pressure of a pipeline leakage part on the leakage stopping plate by using a ball lock structure. However, the following drawbacks still exist in the patent: firstly, the structure of the plugging device is complex, and the cost is high; secondly, the fixing process of the leakage stopping device is complex and is not beneficial to quick leakage stopping; thirdly, because the pipeline is of a circular structure, the chain is difficult to effectively fix the leakage blocking plate due to the reasons of pressure at the leakage part, pipeline vibration, weather change and the like, and the leakage blocking effect of the leakage blocking plate is further influenced.
Chinese patent No. CN 201520182822.6 discloses a pipeline leakage stopping device, including card frame and two sets of symmetrical leaking stoppage mechanisms that set up on the card frame, leaking stoppage mechanism includes adjusting screw, locating lever and leak stopping plate, adjusting screw threaded connection is on the card frame, the one end activity card of locating lever is established in the leak stopping plate, and the other end and adjusting screw threaded connection, during the leaking stoppage, two sets of leaking stoppage mechanisms are fixed on the pipeline through card frame symmetry, and the leak stopping point is stopped up in adjusting screw and leak stopping plate cooperation. The invention can immediately block the leakage point without stopping the transportation when finding the leakage of the pipeline. However, when the leakage plugging plate is matched with the leakage plugging plate to plug the leakage point, the outer wall of the pipeline is exposed to the severe environment outside for a long time, the outer wall is corroded, the leakage plugging plate is not tight in sealing the leakage point, and a small amount of leakage can be caused.
The above-mentioned patent except the problem that exists itself, still has a common short slab, can not realize the bilateral mending-leakage of the inside and outside of pipeline promptly, consequently its extension pipeline live time have certain limitation, only all realize the service life of extension pipeline that the mending-leakage just can be better to the pipeline inside and outside.

The invention utilizes the principle of the first-stage buoyancy and the second-stage buoyancy of the magnetic fluid, namely as shown in figure 1, before coils I and II are not electrified to generate a magnetic field, the first capsule body and the second capsule body can automatically float in the magnetic fluid solution because the permanent magnets are contained in the first capsule body and the second capsule body. When the lower coil II is electrified, the first capsule body and the second capsule body fall down to collide with the crushing cone at the bottom of the frame and are punctured. The A glue and the B glue inside the punctured capsule flow out, and the AB glue exclusively flowing to the inner rubber sheet on the upper right side inside the frame automatically flows out due to the magnetic fluid, and mixing is achieved at the inner rubber sheet. The alternating on and off of the coil I and the coil II can realize the movement of the first capsule body and the second capsule body in the magnetic fluid, so that the glue solution in the first capsule body and the second capsule body can completely flow out.
After AB glue is mixed, the suction pipe is used for sucking from the outer wall of the pipeline, so that the mixed glue solution penetrates through the leakage hole to be sucked to the outer side of the pipeline. After the suction is finished, the guide permanent magnet is moved in a small amplitude, so that the contact surface between the inner film and the inner side of the pipeline can be fully filled with colloid. The inner side and the outer side are fixedly stayed for a period of time to complete the leakage repair of the inner side and the outer side of the pipeline.
The invention has the beneficial effects that: the invention can solve the problem of inner and outer side leakage repair of the leakage part of the pipeline, skillfully utilizes the characteristics of the AB glue, the magnetic fluid and the permanent magnet to complete double-side leakage repair of the pipeline, realizes double insurance for the leakage part of the pipeline and fundamentally prolongs the service life of the pipeline.
