Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing equipment technology, and in particular to a rubber-sealed pipe leak-stopping device. Background Technology
[0002] Pipelines are widely used in industry, urban infrastructure construction, energy, and agriculture, playing a vital role in production and daily life. However, after long-term use, pipelines can leak due to corrosion, material and manufacturing defects, or third-party damage. To quickly reduce and eliminate the impact of pipeline leaks on production and daily life, emergency sealing of the leak point is necessary. Currently used emergency sealing methods include half-joint sealing and wrapping sealing, but these have the following drawbacks: Half-joint sealing requires high compatibility with the pipeline, and half-joints are usually rigid structures, which can easily loosen under pipeline vibration or displacement, leading to re-leakage. Wrapping sealing relies on the wrapping technique and material quality for its sealing effect, and it is not suitable for pipelines with large leaks or high-pressure environments because materials such as tape cannot withstand high pressure, and their performance may deteriorate and lose its sealing effect under special conditions such as high temperatures. Summary of the Invention

[0026] Example 1:
[0027] like Figs. 1-6 A rubber-sealed pipe sealing device includes one or two fixed structures 1 and a sealing pipe that cooperates with them. The fixed structure 1 includes a first half-hoop 5 and a second half-hoop 6 that cooperate to form a full enclosure. The first half-hoop 5 and the second half-hoop 6 have the same structure. The two ends of the first half-hoop 5 and the second half-hoop 6 are connected by a first fastener 9. A sealing sleeve structure that cooperates with the first half-hoop 5 and the second half-hoop 6 is provided between the two. The sealing sleeve structure is sleeved on the outer layer of the sealing pipe. Multiple sets of pressure plates 18 are symmetrically arranged on both sides of the sealing sleeve structure. The symmetrically arranged pressure plates 18 are connected by a second fastener 19.
[0028] In a preferred embodiment, the sealing sleeve structure includes a first sealing half sleeve 12 and a second sealing half sleeve 14 that fit together to form a full enclosure. The first sealing half sleeve 12 is provided with an assembly groove 13, and the second sealing half sleeve 14 is provided with an assembly head 15 that mates with the assembly groove 13. The inner sidewalls of the first sealing half sleeve 12 and the second sealing half sleeve 14 are both provided with positioning grooves 17.
[0029] In a preferred embodiment, the outer walls of the first sealing half-sleeve 12 and the second sealing half-sleeve 14 are provided with limiting holes 16, which cooperate with limiting heads 8 provided on the inner walls of the first half-hoop 5 and the second half-hoop 6.
[0030] In a preferred embodiment, the first half-hoop 5 and the second half-hoop 6 are provided with a groove 7 that mates with the sealing sleeve structure.
[0031] In a preferred embodiment, the sealing tube includes a single rubber sealing ring 2 that mates with a fixed structure 1, and a positioning protrusion 20 that mates with a positioning groove 17 is provided at the middle position of the outer layer of the single rubber sealing ring 2.
[0032] In a preferred embodiment, the sealing tube includes a double rubber sealing ring 3 that cooperates with two fixed structures 1, and the outer layer of the double rubber sealing ring 3 is symmetrically provided with positioning protrusions 20 that cooperate with positioning grooves 17.
[0033] In a preferred embodiment, both the first half-hoop 5 and the second half-hoop 6 are provided with sliding mounting grooves 10, and the sliding mounting grooves 10 are provided with positioning elements 11 that are slidably installed therewith. The positioning elements 11 on two adjacent first half-hoops 5 or second half-hoops 6 are connected and fixed by a third fastener 4.
[0034] In a preferred embodiment, the single rubber sealing ring 2 and the double rubber sealing ring 3 can be various models of rubber sealing rings, such as DN100, DN80, DN70 and DN50, depending on their diameter.
[0035] In a preferred embodiment, the first sealing half-sleeve 12 and the second sealing half-sleeve 14 are made of rubber.
[0036] In a preferred embodiment, the fixing structure 1 can be used in pairs.
[0037] Example 2:
[0038] like Figs. 1-2 The installation and fixing method of the single sealing ring leak sealing device is as follows: the first half-hoop 5 and the second half-hoop 6 are wrapped around both sides of the pipeline leak point and locked by the first fastener 9; the single rubber sealing ring 2 is put on the leak point, and its positioning protrusion 20 is aligned with the positioning groove 17 of the first sealing half-sleeve 12. Then, the assembly head 15 of the second sealing half-sleeve 14 is inserted into the assembly groove 13 to complete the fastening; the sealing sleeve is embedded into the clamping groove 7 as a whole, so that the limiting head 8 is inserted into the limiting hole 16; the pressure plate 18 is symmetrically installed and gradually tightened by the second fastener 19, so that the sealing ring expands radially to fill the leak gap.
[0039] Example 3:
[0040] like Figs. 3-4 In the installation and fixing method of the double sealing ring leak sealing device: two fixing structures 1 are installed on both sides of the pipeline leak point, and the spacing is adjusted by the sliding positioning part 11 and then fixed by the third fastener 4; the positioning protrusions 20 at both ends of the double rubber sealing ring 3 are respectively embedded into the positioning grooves 17 of the sealing sleeves on both sides to form a double sealing barrier; the remaining steps are the same as in embodiment 2, and finally the pressure plate 18 is used to evenly press it, which is suitable for high pressure or long crack conditions.
[0041] The method of using this utility model is as follows:
[0042] The first fastener 18 applies pressure, forcing the inner wall of the sealing sleeve to fit tightly against the pipe surface. Under pressure, the rubber material fills the tiny bumps and depressions, forming the first seal. The engagement of the positioning protrusion 20 and the positioning groove 17 prevents the sealing sleeve from sliding axially, and the limiting head 8 and the limiting hole 16 cooperate to prevent radial displacement. The clamping groove 7 evenly transmits the clamping pressure to the sealing sleeve, and the pressure plate 18 further enhances the local clamping force through the second fastener 19, ensuring that there is no gap between the sealing layer and the pipe. The fixing structure 1 applies pressure as a whole to the sealing pipe, and the sealing pipe is fitted onto the crack in the pipe.
[0043] Rubber sealing rings undergo elastic deformation when the pipeline vibrates or experiences temperature changes, continuously compensating for the gap between the sealing surfaces and preventing seal failure due to material creep.
[0044] The advantages of this utility model are: modular and split design, which can adapt to complex routes of different pipe diameters and also adapt to multi-pipe parallel scenarios; multiple sealing protections, preventing axial movement of the sealing sleeve and avoiding radial movement between the sealing sleeve and the clamp; quicker and more convenient disassembly and assembly, easy maintenance, uniform pressure application and stable pressure resistance, and strong practicality.
