Description

Technical Field

[0001] This utility model relates to the technical field of water pipe plugging devices, specifically a water pipe rupture quick plugging device. Background Technology

[0002] A plug, also known as a clamp or split joint, is a device used for emergency repair of pipeline leaks. It is mainly used for the rapid repair of water supply and drainage, as well as liquid and gas pressure pipelines. Its structure consists of two symmetrical clamping bodies, a sealing ring, and fasteners, which are tightened with bolts and nuts to form a seal.

[0003] Currently, existing plugs are placed outside the leak point during use and then fixed by tightening bolts. However, since the plug needs to withstand the pressure at the leak point during installation, the pressure at the leak point will push the plug away from the pipeline, making the installation difficult. At the same time, since the inner diameter of the plug is constant, a single-size plug cannot meet the maintenance and plugging needs of pipelines of different sizes. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Figures 1-5 The diagram shown is an overall structural schematic of one embodiment of the water pipe rupture quick-sealing device of this utility model. Please refer to [link / reference]. Figures 1-5 This embodiment of a water pipe rupture quick-sealing device includes:

[0031] The main body of the plugging device includes two plugging plates 1 arranged symmetrically in a semi-circular structure. Both ends of the two plugging plates 1 are symmetrically provided with mounting bolts 15. A pressure relief pipe 20 is integrally formed at the center of the outer wall of one of the plugging plates 1. A pressure relief groove 19 is symmetrically opened at the bottom end of the pressure relief pipe 20, and a piston 18 for sealing the pressure relief groove 19 is adjustablely installed in the pressure relief pipe 20.

[0032] The inner lining plate 8 fits the inner wall of the sealing plate 1, and both sides of the outer wall of the inner lining plate 8 are provided with screw holes 9 for connection with the mounting bolts 15.

[0033] In this embodiment, in order to fix the two sealing plates 1 on the damaged water pipe, both ends of the sealing plate 1 are integrally formed with a first protrusion 4. The first protrusion 4 is provided with a plurality of connecting parts 7. A first through hole 6 is opened at the center of the connecting part 7. A fastening bolt 2 is installed at the top of the connecting part 7. The fastening bolt 2 passes through the first through hole 6 and is threaded with a nut 3. After the two sealing plates 1 are fitted on the water pipe, the fastening bolt 2 passes through the first through hole 6 on the connecting part 7 and is threaded with a nut 3. During the tightening process, the nut 3 causes the sealing plate 1 to be squeezed against the damaged part of the water pipe, thereby sealing the damaged part of the water pipe.

[0034] In this embodiment, in order to maintain a seal between the inner liner plate 8 and the outer wall of the water pipe after the sealing plate 1 is installed, the inner wall of the inner liner plate 8 is provided with a first groove 10 on both sides, and a second groove 12 matching the first groove 10 is provided on the connecting part 7. The inner wall of the first groove 10 is integrally formed with equidistant teeth 13, and a sealing plate 5 that fits and is sleeved on the teeth 13 is embedded in the first groove 10. The two ends of the sealing plate 5 are integrally formed with second protrusions 11, which fit and are inserted into the second groove 12. After the two sealing plates 1 are fixed to each other, the sealing plate 1 drives the inner liner plate 8 to press against the outer wall of the water pipe. The sealing plate 5 on the inner wall of the sealing plate 5 is tightly connected to the outer wall of the water pipe, and the second protrusions 11 between the two sealing plates 5 on the same side are tightly connected to each other, so that the two ends of the sealing plate 1 are sealed with the water pipe. The sealing plate 1 and the inner liner plate 8 are both rigid plates, which can avoid deformation when the water pipe is squeezed.

[0035] In this embodiment, in order to achieve the sealing of pipes of different sizes, this application is a preferred solution of the water pipe damage quick sealing device of the present utility model. In this embodiment, the outer wall of the sealing plate 1 has an integrally formed mounting part 14 on both sides. The bottom end of the mounting bolt 15 passes through the mounting part 14 and is threaded into the screw hole 9. The inner wall of the sealing plate 1 has a sealing gasket 16 embedded on both sides. The sealing gasket 16 is tightly connected to the outer wall of the inner liner plate 8. After unscrewing the mounting bolt 15, the inner liner plate 8 in the sealing plate 1 is disassembled. After replacing the inner liner plate 8 with one that matches the outer wall of the water pipe, the inner liner plate 8 is placed on the inner wall of the sealing plate 1. The mounting bolt 15 is threaded into the screw hole 9 to keep the inner liner plate 8 and the sealing plate 1 fixed.

[0036] In this embodiment, to drain the water from the water pipe during the installation of the sealing plate 1, a second through hole 17 is provided at the center of the inner lining plate 8. The second through hole 17 is located between the two sealing gaskets 16 and is connected to the pressure relief pipe 20. A screw 22 is threadedly inserted into the top of the pressure relief pipe 20. The bottom end of the screw 22 is rotatably mounted in the piston 18 via a bearing. A knob 21 is integrally formed at the top of the screw 22. When the sealing plate 1 is installed, the knob 21 is held to rotate the screw 22. During the rotation of the screw 22, the piston 18 is moved upward, causing the piston 18 to move. When the sealing plate 1 is installed above the pressure relief groove 19, the second through hole 17 on the inner liner 8 is aligned with the damaged position of the pipe. Water discharged from the damaged position of the water pipe is discharged from the pressure relief groove 19 along the second through hole 17 and the pressure relief pipe 20. The sealing gaskets 16 on both sides of the inner wall of the sealing plate 1 can block the discharged water flow and prevent water from being discharged from the gap between the sealing plate 1 and the inner liner 8. After the sealing plate 1 is installed, the knob 21 is held to drive the screw 22 to rotate, so that the piston 18 at the bottom of the screw 22 moves downward and is tightly connected to the inner wall of the sealing pipe, so that the bottom end of the pressure relief pipe 20 is sealed.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
