Description

Technical Field

[0001] The present application relates to a temporary pipeline repair device. Background Art

[0002] After a metal pipe is damaged, in order to maintain normal use, it is sometimes necessary to temporarily repair it in the operating state. For the adsorption of metal pipes, an external extrusion component is now mostly used to seal the damaged position through the extrusion component to achieve the purpose of repair. The existing extrusion component generally adopts a plug-in structure, which is fixed by external clamping. The final sealing effect is average, and the maintenance time is also short. The operation difficulty during the sealing is also relatively large. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a temporary pipeline repair device, including two pressing pieces arranged opposite to each other, a connecting portion is arranged at the edge of the pressing piece, an arc-shaped cavity is arranged in the middle of the pressing piece, and the arc-shaped cavity is arranged to bulge outward in the direction away from the other pressing piece; a flexible cushion layer is arranged on the inner side of the pressing piece, and the flexible cushion layer extends to the position of the connecting portion. The present application forms an integral pressing structure through the flexible cushion layer and the pressing piece, and then the arc-shaped cavity forms a space for accommodating the pipeline, so that the temporary repair of the pipeline can be better completed by applying force to the flexible cushion layer through the side connecting portion. During use, the damaged part is generally arranged in the arc-shaped cavity to increase the sealing contact area as much as possible.

[0004] Preferably, the flexible cushion layer includes a raised portion arranged in the middle of the pressing piece, and extends from the raised portion to the edge of the connecting portion and the pressing piece, and the thickness gradually becomes thinner. The flexible cushion layer of the present application adopts a method of being raised in the middle and extending and thinning on the outside. This shape allows better sealing during the extrusion process, preventing the internal fluid from leaking to the outside, and completing the sealing at the damaged edge.

[0005] Preferably, the flexible cushion layer is a silicone layer, and the thickest part of the raised portion of the silicone layer is not less than 1.5 mm.

[0006] Preferably, an indium plate is further provided between the silicone layer and the pressing member, and the indium plate is a plate of uniform thickness, and the thickness of the indium plate is not less than 0.5 mm.

[0007] Preferably, the indium plate is laid in abutment in the arc cavity. The indium plate and the silicone layer are used in the present application to seal high-pressure pipes. When the pressure is about 1MPa or exceeds 1MPa, the silicone layer has poor sealing effect. The addition of the indium plate can better ensure the sealing effect.

[0008] Preferably, the connecting portion includes a plurality of connecting plates arranged on the pressing piece, corresponding connecting bolt holes are arranged on the connecting plates, locking bolts are arranged in the connecting bolt holes, and locking nuts are respectively arranged on both sides of the locking bolts corresponding to the pressing piece.

[0009] Preferably, arc-shaped grooves are provided between adjacent connecting plates.

[0010] Preferably, the length of the pressing member is not less than 25 cm.

[0011] This application can bring the following beneficial effects:

[0012] 1. The present application forms an integral pressing structure through a flexible cushion layer and a pressing piece, and then an arc-shaped cavity forms a space for accommodating the pipeline, so that the temporary repair of the pipeline can be better completed by applying force to the flexible cushion layer by the side connection part. During use, the damaged part is generally arranged in the arc-shaped cavity to increase the sealing contact area as much as possible.

[0013] 2. The flexible cushion layer of the present application is convex in the middle and extends and thins on the outside. This shape allows for better sealing during the extrusion process, preventing the internal fluid from leaking to the outside and completing the sealing at the damaged edge.

[0014] 3. The present application adopts the method of auxiliary setting of indium plate and silicone layer, which is suitable for sealing high-pressure pipelines. When the pressure is around 1MPa or exceeds 1MPa, the sealing effect of the silicone layer is poor, and the addition of indium plate can better ensure the sealing effect.

[0021] In order to clearly illustrate the technical features of the present solution, the present application is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0022] In the first embodiment, if Figure 1 As shown, a temporary pipeline repair device comprises two pressing pieces 1 arranged opposite to each other, a connecting portion 2 is arranged at the edge of the pressing piece 1, an arc-shaped cavity 3 is arranged in the middle of the pressing piece 1, and the arc-shaped cavity 3 is arranged to bulge outward in the direction away from the other pressing piece 1; a flexible cushion layer 4 is arranged on the inner side of the pressing piece 1, and the flexible cushion layer 4 extends to the position of the connecting portion 2.

[0023] When in use, select a pressing piece that is 30 cm longer than the damaged position, set the damaged position in the middle, then match the middle of the pressing piece with the damaged position, and then dock the connecting parts. Through the connection between the connecting pieces, squeeze the flexible cushion layer 4 so that the medium of the flexible cushion layer can penetrate into the damaged position, and then squeeze the external flexible cushion layer 4 to complete the temporary repair of the pipeline by the pressing piece.

[0024] In the second embodiment, if Figure 1-5 As shown, a temporary pipeline repair device includes two pressing pieces 1 arranged opposite to each other, a connecting portion 2 is arranged at the edge of the pressing piece 1, and an arc-shaped cavity 3 is arranged in the middle of the pressing piece 1, and the arc-shaped cavity 3 is arranged to bulge outward in the direction away from the other pressing piece 1; a flexible cushion layer 4 is arranged on the inner side of the pressing piece 1, and the flexible cushion layer 4 extends to the position of the connecting portion 2. The flexible cushion layer 4 includes a bulge 5 arranged in the middle of the pressing piece 1, and extends to the connecting portion 2 and the edge of the pressing piece 1 with the bulge 5 as the center, and the thickness gradually becomes thinner. The flexible cushion layer 4 is a silicone layer, and the thickest part of the bulge 5 of the silicone layer is not less than 1.5 mm. An indium plate 6 is also arranged between the silicone layer and the pressing piece 1, and the indium plate 6 is a plate of equal thickness, and the thickness of the indium plate 6 is not less than 0.5 mm. The indium plate 6 is laid in abutment in the arc-shaped cavity 3. The connecting portion 2 includes a plurality of connecting plates 7 arranged on the pressing member 1, and corresponding connecting bolt holes 8 are arranged on the connecting plates 7, and locking bolts 9 are arranged in the connecting bolt holes 8. Locking nuts 10 are respectively arranged on both sides of the locking bolts 9 corresponding to the pressing member 1. An arc groove 11 is arranged between adjacent connecting plates 7.
