Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a pipeline plug and a pipeline repairer. Background Art

[0002] Existing water, gas, and water supply pipelines are typically buried underground. Water, gas, and other leaks frequently occur due to pipeline ruptures caused by various reasons. A half joint is a device used to quickly repair damaged pipelines. Because the media within the pipeline is pressurized, a pressure relief hole is typically installed in the half joint. After installation, the pressure relief hole is sealed with a plug, achieving rapid repair of the damaged pipeline.

[0003] The pipe plug includes a threaded mounting portion and a sealing portion located at one end thereof. When there is pressure in the pipe, water and gas will form resistance to the plugging of the plug during the installation process, causing the sealing portion to be unable to be installed in place, resulting in plugging failure. In order to solve the pressure problem, some manufacturers set through holes on the side walls of the threaded mounting portion to relieve pressure during the installation process. However, if the through hole is set too small, the pressure relief effect is not ideal. If the through hole is set too large, the mechanical strength of the threaded mounting portion is affected, which will cause assembly difficulties on the one hand and greatly increase the risk of breakage on the other hand. Therefore, it is necessary to design a new plug structure to ensure the pressure relief effect while ensuring its mechanical strength. Utility Model Content

[0022] like Figures 1 to 5 As shown, Figure 1 This is a top perspective schematic diagram of an embodiment of a pipe plug proposed by the utility model. Figure 2 This is a bottom-up perspective diagram of an embodiment of a pipe plug proposed by the utility model. Figure 3 This is a structural diagram of an embodiment of a pipeline repair device proposed by the utility model. Figure 4 This is a schematic axial cross-sectional view of an embodiment of a pipeline repair device proposed in the present invention. Figure 5 for Figure 4 A partial schematic diagram of .

[0023] Reference Figure 1 and 2 The utility model proposes a pipe plug, comprising: a threaded pipe 1 and a blocking end 2 arranged at one end of the threaded pipe 1; the threaded pipe 1 is provided with a through slot extending from the end away from the blocking end 2 to the middle, and the end of the slot away from the blocking end 2 is provided with a connecting rib 3 arranged across the slot, and the connecting rib 3 is located inside the threaded pipe 1.

[0024] To explain in detail how to use the pipe plug, refer to Figure 3 This embodiment also provides a pipeline repair device including the aforementioned pipeline plug. Specifically, the pipeline repair device of this embodiment further includes an upper shell 10 and a lower shell 20, which are detachably connected via fasteners. Two annular sealing structures 30 are disposed between the upper shell 10 and the lower shell 20 for sealing. The two annular sealing structures 30, the upper shell 10, and the lower shell 20 together form a sealed cavity surrounding the pipeline. The outer wall of the sealed cavity is provided with a pressure relief hole for mounting the aforementioned pipeline plug.

[0025] During the specific operation of the pipeline repair device of this embodiment, refer to Figure 4 and 5 , install the upper and lower shells on either side of the pipeline leak. The two annular sealing structures are located on either side of the leak. Bolts, nuts, and other fasteners secure the upper and lower shells together, forming an annular sealed cavity surrounding the leak. Next, install the pipe plug over the pressure relief hole. During installation, the pipe plug is threaded into the pressure relief hole, allowing pressure within the sealed cavity to escape through the notch, making it easy to install the plug over the pressure relief hole.

[0026] In actual use, the pipe plug of this embodiment can also be directly installed at the position on the pipe that needs to be sealed, such as a leak port or a pipe port, etc., and the threaded tube of the pipe plug and the thread of the installation port can be easily connected, avoiding the defect that the existing pipe plug cannot be installed due to pressure in the pipe.

[0027] In the present embodiment, the proposed pipe plug comprises a threaded pipe and a sealing end arranged at one end of the threaded pipe. The threaded pipe is provided with a through slot extending from the end away from the sealing end to the middle part. The slot is provided with a connecting rib arranged across the slot at the end away from the sealing end, and the connecting rib is located inside the threaded pipe. Through the above-optimized design of the pipe plug, by arranging the slot and the connecting rib at the end of the slot, the mechanical strength of the threaded pipe is ensured, the threaded pipe is easy to assemble, and when the pipe is installed, the water and gas in the pipe can be discharged from the end face and the inside of the threaded pipe at the same time, thereby greatly increasing the effective water and gas discharge area and improving the pressure relief effect.

[0028] In a specific embodiment, the connecting rib 3 has an arc-shaped structure protruding towards the inside of the threaded pipe 1 at the middle part. The connecting rib is bent towards the inside of the threaded pipe, thereby ensuring the support strength at the end of the slot. At the same time, a three-dimensional water and gas discharge space is formed at the position of the slot, and when the threaded pipe is installed at the pipe opening, two water and gas discharge ports are formed at the inner wall and the end face of the threaded pipe, thereby greatly improving the water and gas discharge efficiency.

[0029] In order to improve the mechanical strength at the position of the slot, in other specific embodiments, the two sides of the slot are provided with reinforcing ribs 4 extending towards the inside of the threaded pipe 1, and the two ends of the connecting rib 3 are connected with the two reinforcing ribs 4 respectively. The slot position is reinforced by the reinforcing ribs and the connecting rib.

[0030] In a further specific design, the sealing end 2 is provided with a reinforcing boss 5 near one side of the threaded pipe 1, and the reinforcing ribs 4 extend from the reinforcing boss 5 to the direction away from the sealing end 2 at the two sides of the slot. The reinforcing boss is used to reinforce the bottom of the slot. Specifically, the projection of the connecting rib 3 on the plane of the sealing end 2 is located on the reinforcing boss 5.

[0031] In actual design, a plurality of slots can be arranged on the side wall of the threaded pipe. The threaded pipe 1 comprises a plurality of arc-shaped walls distributed along the circumference thereof, and the slot is formed between two adjacent arc-shaped walls. Specifically, the side wall of the threaded pipe 1 is provided with a plurality of slots uniformly distributed along the circumference.

[0032] In other specific embodiments, in order to facilitate the installation of the plug, the sealing end 2 is provided with a force receiving part 6 for screwing away from one side of the threaded pipe 1. When tightening the plug, the force receiving part 6 can be turned by a wrench to achieve the purpose of saving labor. The force receiving part 6 can be designed as a protrusion or a groove, and the shape can be hexagonal nut-shaped or quadrilateral-shaped.

[0033] Reference Figure 3 In the specific design of the force receiving part 6, the force receiving part 6 can be formed by arching the middle part of the sealing end 2 away from the threaded pipe 1. In this way, a groove structure is formed inside the sealing end, and a water and gas space is formed inside the plug after the plug is installed, thereby increasing the accommodation space for the water and gas not discharged in the pipe.

[0034] In the specific dimensional design, the outer diameter of the plugging end is larger than that of the threaded tube. This allows the plugging end to press against the pipe opening when the pipe plug is screwed onto the pipe opening to be sealed, further improving the seal. Furthermore, the distance from the bottom of the notch to the plugging end 2 is less than the notch depth, placing the bottom of the notch as close to the plugging end as possible. This increases the effective drainage and air venting area while maximizing drainage and air venting during installation.

[0035] In addition, in the specific installation method of the pipe plug, sealing can be achieved by wrapping raw tape around the outside of the threaded pipe. To facilitate operation, the pipe plug may also include a sealing gasket 7, with an opening in the middle of the sealing gasket 7 that cooperates with the threaded pipe 1, and a sealing groove for accommodating the sealing gasket 7 on the side of the plugging end 2 close to the threaded pipe 1. During installation, there is no need to wrap raw tape, and the sealing gasket can be directly used to seal the hand surface. Preferably, the sealing gasket has a rectangular cross-section to ensure that the sealing gasket does not deviate within the sealing groove. At the same time, the contact area with the pressure relief hole position on the hand surface is increased, thereby ensuring sealing reliability.

[0036] In a specific design of the pipeline repair device, the annular sealing structure may adopt a sealing ring, and corresponding sealing grooves are provided on the inner walls of the upper and lower shells.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
