Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, and in particular to a pipe-wrapping construction tool for eliminating pipeline leaks. Background Technology

[0002] In the oil refining and chemical industry, when pipelines experience corrosion and thinning during production and operation, resulting in leaks, for localized leak points, when the pipeline system cannot be shut down, pressurized leak sealing methods are usually used to treat the leaks, such as pipe clamping or clamping.

[0003] The pipe clamp method mainly includes semi-circular or full-circular clamps, sealing gaskets, and fastening devices. Currently, the existing pipe clamp method is generally suitable for leaks with small leakage points. For leaks with longer cracks, it is difficult to plug them. Moreover, during installation, the medium inside the pipe can easily spray out from around the clamp, which not only affects operational safety but also increases the difficulty of subsequent cleaning. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the sealing surface is small and the medium inside the pipe will spray out from around the pipe clamp, increasing the cleaning burden. Therefore, this invention proposes a pipe-wrapping construction tool for eliminating leaks in pipelines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe sealing construction tool for eliminating leaks includes a second hoop plate with a semi-circular structure. The length of the second hoop plate extending along the axial direction is greater than its diameter. A second sealing gasket is provided on the inner wall of the second hoop plate. A pressure relief pipe with a valve is detachably installed on the second hoop plate. An avoidance groove is opened on the second sealing gasket, and the crack is located in the avoidance groove. One end of the pressure relief pipe is connected to the avoidance groove, and the second hoop plate is fixed to the pipe through a connecting part.

[0007] To facilitate fixing the second hoop to the pipe, preferably, the connecting part includes a first hoop with a semi-circular structure, one side of the second hoop is rotatably connected to the first hoop, the other side of the second hoop is fixedly connected to the first hoop by bolts, and a first sealing gasket is provided inside the first hoop.

[0008] To ensure reliable rotation between the second hoop and the first hoop, a rotating plate is fixedly provided on one side of the second hoop, and a rotating seat is fixedly provided on one side of the first hoop, with the rotating plate and the rotating seat being rotatably connected.

[0009] Furthermore, a second fixing plate is fixedly installed on the other side of the second hoop, and a first fixing plate is fixedly installed on the other side of the first hoop. Both the first fixing plate and the second fixing plate have through holes, and one end of the bolt passes through the through hole and is threadedly connected to a nut.

[0010] To facilitate the installation of the sealing gasket, the inner walls of both the first hoop and the second hoop are provided with installation grooves, and both the first sealing gasket and the second sealing gasket are placed in the installation grooves, with the thickness of both the first sealing gasket and the second sealing gasket being greater than the depth of the installation groove.

[0011] Preferably, the second sealing gasket is made of polytetrafluoroethylene.

[0012] Compared with the prior art, this utility model provides a pipe wrapping construction tool for eliminating pipeline leaks, which has the following beneficial effects:

[0013] 1. This pipe leak-eliminating and sealing construction tool uses a pressure relief pipe with a valve installed on the second hoop plate. A second sealing gasket is installed on the inner wall of the second hoop plate, and an avoidance groove is opened on the second sealing gasket. The crack is located in the avoidance groove. The second sealing gasket with an appropriate length of avoidance groove can be selected according to the length of the crack, which is convenient for sealing longer cracks. Moreover, during the tightening of the second hoop plate, most of the leaked medium is discharged to the outside through the pressure relief pipe, reducing the amount sprayed from the perimeter of the second hoop plate, which can effectively reduce the operational risk and the difficulty of subsequent cleaning.

[0014] 2. The pipe leak-eliminating casing construction tool has installation grooves on the inner walls of both the first and second clamp plates. The first and second sealing gaskets are placed in the installation grooves, which can ensure the reliable position of the first and second sealing gaskets, reduce movement within the first and second clamp plates, improve the sealing effect, and when the first and second clamp plates are pushed to move on the pipeline, the first and second sealing gaskets can be moved together, making it convenient for transfer.

[0015] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model provides a pressure relief pipe with a valve on the second hoop plate, installs a second sealing gasket on the inner wall of the second hoop plate, and provides an avoidance groove on the second sealing gasket. The crack is located in the avoidance groove. The second sealing gasket with an avoidance groove of appropriate length can be selected according to the length of the crack, which is convenient for sealing longer cracks. Moreover, during the process of tightening the second hoop plate, most of the leaked medium is discharged to the outside through the pressure relief pipe, reducing the amount sprayed from all sides of the second hoop plate, which can effectively reduce the operational risk and the difficulty of subsequent cleaning.

[0023] Example:

[0024] Reference Figures 1-4A pipe sealing construction tool for eliminating leaks includes a second hoop plate 2 with a semi-circular structure. The length of the second hoop plate 2 extending along its axis is greater than its diameter. The length of the second hoop plate 2 is 10-500mm, preferably 100mm. A second sealing gasket 301 is provided on the inner wall of the second hoop plate 2. A pressure relief pipe 4 with a valve is detachably installed on the second hoop plate 2. The pressure relief pipe 4 is preferably threaded to the second hoop plate 2. The threaded connection between the pressure relief pipe 4 and the second hoop plate 2 is preferably a sealing pipe thread. A sealing gasket is provided at the connection between the pressure relief pipe 4 and the second hoop plate 2 to ensure a sealing effect at the connection. An avoidance groove 302 is provided on the second sealing gasket 301. The length of the second sealing gasket 301 is preferably 99mm, and the length of the avoidance groove 302 is 70mm. The crack is located within the avoidance groove 302. During use, a suitable valve is selected according to the length of the crack. The second sealing gasket 301 of the length relief groove 302 can seal longer cracks and improve the performance. One end of the pressure relief pipe 4 is connected to the relief groove 302, and the second clamp 2 is fixed to the pipe through the connecting part. In use, by installing the second sealing gasket 301 in the second clamp 2, opening the valve on the pressure relief pipe 4, and then covering the leaking pipe with the second clamp 2, the leak point is located in the relief groove 302. At this time, most of the leaking medium is discharged to the outside through the pressure relief pipe 4. Then, the connecting part is used to gradually fix the second clamp 2 to the pipe. A collection device, such as a bucket, is connected to the end of the pressure relief pipe 4 away from the second clamp 2 to collect the leaking medium, reduce waste, and reduce the amount of medium sprayed from around the second clamp 2, thereby improving safety and reducing cleaning difficulty. After the second clamp 2 is completely fixed to the pipe, the valve on the pressure relief pipe 4 is closed.

[0025] In use, a pressure relief pipe 4 with a valve is installed on the second hoop 2, and a second sealing gasket 301 is installed on the inner wall of the second hoop 2. A relief groove 302 is provided on the second sealing gasket 301, and the crack is located in the relief groove 302. The second sealing gasket 301 with a relief groove 302 of appropriate length can be selected according to the length of the crack, which is convenient for sealing long cracks. Moreover, during the process of tightening the second hoop 2, most of the leaked medium is discharged to the outside through the pressure relief pipe 4, reducing the amount sprayed from all sides of the second hoop 2, which can effectively reduce the operational risk and the difficulty of subsequent cleaning.

[0026] Reference Figures 1-3The connecting part can be fixed to the pipe using clamps or similar means. Here, we design the connecting part as a first clamp 1 with a semi-circular structure. The materials of both the first clamp 1 and the second clamp 2 are preferably stainless steel. One side of the second clamp 2 is rotatably connected to the first clamp 1, and the other side of the second clamp 2 is fixedly connected to the first clamp 1 by bolts. A first sealing gasket 3 is provided inside the first clamp 1. In use, the second clamp 2 is placed over the leak in the pipe, and then the first clamp 1 is flipped over so that it also covers the outer wall of the pipe. Then, the second clamp 2 is connected to the first clamp 1 with bolts, and the bolts are tightened to fix the second clamp 2 and the first clamp 1 to the pipe. Moreover, the first sealing gasket 3 is provided on the inner wall of the first clamp 1, which can not only further improve the sealing effect, but also reduce the pressure damage to the outer wall of the pipe and improve the performance.

[0027] Reference Figures 1-3 A rotating plate 201 is fixedly installed on one side of the second hoop 2, and a rotating seat 101 is fixedly installed on one side of the first hoop 1. The rotating plate 201 and the rotating seat 101 are rotatably connected. In use, by fixing the rotating plate 201 on the second hoop 2 and the rotating seat 101 on the first hoop 1, the rotation effect between the second hoop 2 and the first hoop 1 can be guaranteed.

[0028] Reference Figures 1-3 A second fixing plate 202 is fixedly installed on the other side of the second hoop plate 2, and a first fixing plate 102 is fixedly installed on the other side of the first hoop plate 1. Both the first fixing plate 102 and the second fixing plate 202 have through holes, with two to six sets of through holes. Here, we prefer three sets. One end of the bolt is threaded through the through hole and connected to a nut. In use, the first fixing plate 102 is fixedly installed on the first hoop plate 1, and the second fixing plate 202 is fixedly installed on the second hoop plate 2. Both the first fixing plate 102 and the second fixing plate 202 have through holes, which facilitates the connection with bolts, ensuring reliable fixation and convenient assembly and disassembly.

[0029] Reference Figure 3 The first hoop plate 1 and the second hoop plate 2 are both provided with mounting grooves. The first sealing gasket 3 and the second sealing gasket 301 are both placed in the corresponding mounting grooves. The thickness of the first sealing gasket 3 and the second sealing gasket 301 is greater than the depth of the mounting groove. In use, by providing mounting grooves in the inner walls of the first hoop plate 1 and the second hoop plate 2, the first sealing gasket 3 and the second sealing gasket 301 can be placed in the mounting grooves, which can ensure the reliable position of the first sealing gasket 3 and the second sealing gasket 301, reduce movement within the first hoop plate 1 and the second hoop plate 2, and improve the sealing effect. Moreover, when the first hoop plate 1 and the second hoop plate 2 are moved on the pipeline, the first sealing gasket 3 and the second sealing gasket 301 can be moved together, which is convenient for transfer.

[0030] Reference Figures 1-3 The second sealing gasket 301 is made of polytetrafluoroethylene (PTFE), and the first sealing gasket 3 is also made of PTFE. PTFE has excellent chemical stability, hardly reacts with any chemical substances, and has a wide operating temperature range, maintaining good performance between -200°C and +260°C to ensure the requirements of use.
