Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline maintenance, and in particular relates to a pipeline repair component. Background Technology

[0002] Pipeline repair refers to the use of various techniques to restore damaged or leaking pipelines to their normal function. Depending on the type of pipeline material and its purpose, there are many different repair methods, among which welding and chemical bonding are the most common.

[0003] After years of operation, pipelines inevitably suffer various damages and leaks due to corrosion, poor operation and management, etc., resulting in serious economic losses. Therefore, pipeline repair is necessary. When repairing gas pipelines, repair agents are usually used for bonding. However, the strength of the repair agent is limited, the repair life is limited, and the gas pressure also affects the solidification effect of the repair agent during the pressurized repair process.

[0005] This utility model embodiment is implemented as follows: a pipe repair component includes a gas pipe, a cover plate installed on the outside of the gas pipe, a reinforcing cloth wrapped around the surface of the gas pipe, and a fixing component clamped on the outside of the cover plate. The surface of the gas pipe is damaged. The cover plate includes two plates and a sealing gasket. One side of the two plates is hinged to each other and installed on the outside of the gas pipe. The other side of each of the two plates is fixedly provided with an installation plate. The sealing gasket is fixedly installed on the inner edge of the plate. One plate has a liquid injection port on its surface. The middle part of the reinforcing cloth is wrapped around the surface of the gas pipe.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model provides a pipe repair component. By setting a fixing component, the plate is fixedly installed on the outside of the gas pipe. A repair agent is filled into the gap between the plate and the gas pipe through a set injection port. The sealing gasket is set to improve the sealing effect and prevent the repair agent from seeping out. The reinforcing cloth set can improve the solidification speed of the repair agent and also increase the strength of the repair agent after solidification.

[0013] This utility model provides a pipe repair component that clamps the two ends of a reinforcing fabric using clamping plates one and two, and a rotating adjustment unit tightens the reinforcing fabric to the damaged surface.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1 to 4 As shown, an embodiment of this utility model provides a pipe repair component, including a gas pipe 1, a cover plate 2 installed on the outside of the gas pipe 1, a reinforcing fabric 3 wrapped around the surface of the gas pipe 1, and a fixing component 4 clamped on the outside of the cover plate 2. The surface of the gas pipe 1 has a break 11. The cover plate 2 includes two plates 21 and a sealing gasket 22. The two plates 21 are hinged to each other on one side and installed on the outside of the gas pipe 1. The other side of each of the two plates 21 is fixedly provided with a mounting plate 211. The sealing gasket 22 is fixed. Installed on the inner edge of the plate 21, one of the plate 21 has a liquid injection port 214 on its surface, the middle part of the reinforcing cloth 3 is wrapped around the surface of the gas pipe 1, and the two ends of the reinforcing cloth 3 extend through the gap between the two mounting plates 211 to the outside of the mounting plates 211. The fixing assembly 4 includes two fixing plates 41, two clamping bolts 42 and two nuts 43. The two clamping bolts 42 are squeezed and clamped on the outside of the two mounting plates 211, and the clamping bolts 42 and nuts 43 are fixedly installed at both ends of the two clamping bolts 42.

[0024] In one embodiment of this utility model, the plate 21 is fixedly installed on the outside of the gas pipeline 1 by setting the fixing component 4. The repair agent is filled into the gap between the plate 21 and the gas pipeline 1 through the set liquid injection port 214. The sealing gasket 22 is used to improve the sealing effect and prevent the repair agent from seeping out. The reinforcing cloth 3 can improve the solidification speed of the repair agent and also increase the strength of the repair agent after solidification.

[0025] like Figure 2 As shown, in another embodiment of this utility model, the sealing gasket 22 includes an arc-shaped gasket 221 and a straight gasket 222. Both the arc-shaped gasket 221 and the straight gasket 222 are made of elastic material. The arc-shaped gasket 221 and the straight gasket 222 are connected as a whole. The arc-shaped gasket 221 is fixedly installed at both ends of the inner side of the plate 21. The plate 21 has a sealing gasket groove 212 on the inner side corresponding to the straight gasket 222. The straight gasket 222 is fixedly installed in the sealing gasket groove 212.

[0026] In one embodiment of this utility model, the sealing effect of the plate 21 is improved by the mutual compression of the arc-shaped pad 221 and the straight pad 222, thereby preventing the repair agent from leaking and ensuring the stability of the gas pressure inside the plate 21, thus reducing the impact of gas ejection at the damaged 11 points on the solidification of the repair agent.

[0027] like Figure 2 As shown, in another embodiment of the present invention, the reinforcing fabric 3 is made of fiber material, and a tensioning component 5 is provided at the end of the reinforcing fabric 3. The tensioning component 5 includes a first clamp 51, a second clamp 52 and an adjustment unit 54. The first clamp 51 and the second clamp 52 are squeezed and clamped on the outer sides of both ends of the reinforcing fabric 3.

[0028] Specifically, the first clamping plate 51 is movably mounted with fixing bolts 53 at both ends, and the second clamping plate 52 has threaded holes at both ends corresponding to the fixing bolts 53. The lower end of the fixing bolts 53 movably passes through the first clamping plate 51 and is fixedly installed in the threaded holes at the top of the second clamping plate 52. The first clamping plate 51 and the second clamping plate 52 have multiple threaded through holes on their sides corresponding to the adjustment unit 54. The adjustment unit 54 movably passes through the first clamping plate 51 and the second clamping plate 52. The adjustment unit 54 includes an adjustment bolt 541 and a rubber pad 542. The rubber pad 542 is fixedly installed at one end of the adjustment bolt 541.

[0029] In one embodiment of this utility model, the two ends of the reinforcing cloth 3 are clamped by the clamping plate 51 and the clamping plate 52, and the rotating adjustment unit 54 is used to tighten the reinforcing cloth 3 on the surface of the damaged 11. As a result, after the reinforcing cloth 3 absorbs and solidifies the repair agent, a better surface condition can be obtained, ensuring that the strength is the same in all parts of the surface.

[0030] like Figure 4As shown, in another embodiment of the present invention, a tensioning strip 213 is fixedly provided on the inner side of the plate 21, the tensioning strip 213 presses against the outer side of the reinforcing cloth 3, and the outer side of the tensioning strip 213 is provided with rounded corners.

[0031] In one embodiment of this utility model, by pressing the reinforcing cloth 3 with the tensioning strip 213 and then tightening the reinforcing cloth 3 with the tensioning component 5, the reinforcing cloth 3 can be made to completely wrap the surface of the gas pipeline 1 as much as possible.

[0032] like Figure 3 As shown, in another embodiment of the present invention, a sealing ring 23 is fixedly installed at the end of the injection port 214, and the sealing ring 23 is made of an elastic material.

[0033] In one embodiment of this utility model, by setting a ground sealing ring 23, the overall sealing effect can be improved when the repair agent is injected into the plate 21, and the repair agent can be prevented from flowing out from the injection port 214 during the injection process.
