Description

Technical Field

[0001] This invention relates to the field of wall-penetrating insulation pipe technology, specifically to a wall-penetrating sealing structure for insulation pipes and its installation method. Background Technology

[0002] In actual construction of through-wall insulation pipes, due to poor sealing between the outer diameter of the insulation pipe and the manhole wall, and the thermal expansion and contraction of the insulation pipe due to temperature changes, groundwater can leak into the manhole when the groundwater level is high. This can damage valves, compensators, and other components within the manhole, reducing their service life. Therefore, sealing the insulation pipe is usually necessary to prevent continuous seepage and extend its lifespan. Current through-wall sealing structures typically use simple through-wall sleeves, which offer poor sealing and are not easily adaptable to the changes caused by temperature variations in the pipe. While some insulation pipes are designed for expansion and contraction, and others use corrugated pipes for sealing, after prolonged use, the corrugated pipes may leak due to metal fatigue and other factors. When replacement is needed, the insulation pipe cannot be disassembled. To fit the corrugated pipe, it is usually necessary to cut the corrugated pipe into two halves and then weld them together, which directly affects the service life of the corrugated pipe. Moreover, the welding process is relatively complicated, making it inconvenient to pre-store the expansion and contraction sections of the corrugated pipe, resulting in low replacement efficiency and difficulty in quickly sealing leaks. At the same time, it is difficult to identify the location of leaks when manually inspecting for leaks, and it is not convenient to guide the leaking water in sections.

[0003] Therefore, we propose a wall-penetrating sealing structure for insulated pipes and its installation method. Summary of the Invention

The structure employs an adjusting flange ring on the outer side of the corrugated protrusions on the compensating corrugated pipe, facilitating quick maintenance and repair. In cases where cracks appear due to long-term expansion and contraction, rapid patching and repair are possible, simplifying the process and reducing repair costs. The two-part snap-ring connector facilitates subsequent disassembly without requiring the removal of the already installed insulation pipe body. Furthermore, the adjusting flange allows for the pre-storage of a section of the compensating corrugated pipe for backup, avoiding the need for complete removal and replacement of traditional corrugated pipes in case of leakage. This pre-storage method effectively extends the service life of this structure.

[0016] Using external and internal connectors, and by utilizing their different installation locations, they can be used to collect leakage water between the corrugated pipe sleeve and the well wall, as well as inside the corrugated pipe sleeve. This makes it easier for staff to identify the location of the leak, avoiding tedious subsequent inspections and improving maintenance efficiency. Leakage between the corrugated pipe sleeve and the well wall is usually caused by a poor seal between the sleeve flange end and the well wall; while leakage inside the corrugated pipe sleeve is usually caused by leakage in the compensating corrugated pipe. This allows staff to easily identify the location requiring maintenance. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 10 As shown: This invention provides a technical solution: a wall-penetrating sealing structure for an insulated pipe, comprising a wall-penetrating mounting component 1, a corrugated pipe compensating component 2 mounted on the wall-penetrating mounting component 1, the corrugated pipe compensating component 2 being used for pre-storing compensation distance; a retaining ring connector 3 mounted on the corrugated pipe compensating component 2; the retaining ring connector 3 being used for sealing the corrugated pipe compensating component 2; an outer receiving component 4 and an inner receiving component 5 mounted at the tail of the wall-penetrating mounting component 1; the outer receiving component 4 and the inner receiving component 5 being used for receiving leaking water; the wall-penetrating mounting component 1 includes: an insulated pipe body 101, a corrugated pipe sleeve 102, and a threaded connecting pipe 1021, the outer side of the insulated pipe body 101 being provided with an insulation layer; the outer side of the insulated pipe body 101 being provided with a corrugated pipe sleeve 102; the side of the corrugated pipe sleeve 102 being provided with a hollow cavity; the tail of the corrugated pipe sleeve 102 being fixedly mounted with a threaded connecting pipe 1021; the outer side of the threaded connecting pipe 1021 being provided with threads.

[0021] The through-wall mounting component 1 further includes: a sleeve flange 1022, a cover 103, and a cover flange 1031. The sleeve flange 1022 is fixedly fitted onto the corrugated pipe sleeve 102. Two rubber sealing rings are provided on the inner side of the sleeve flange 1022. Two cover 103s are provided, and the two cover 103s are connected by bolts. Cover flanges 1031 are fixedly installed on the two cover 103s respectively. The two cover 103s are located outside the insulation pipe body 101. The flange holes on the two cover flanges 1031 correspond to the flange holes on the sleeve flange 1022. The two cover flanges 1031 and The casing flange 1022 is attached to each other; the two cover flanges 1031 and the casing flange 1022 are used to be bolted to the well wall; the bellows compensation component 2 includes: a compensation bellows 201 and an end plate 2011, the tail end of the compensation bellows 201 is sleeved in the hollow cavity on the side of the bellows sleeve 102; the compensation bellows 201 is located inside the two covers 103; the end plate 2011 is welded to the outside of the insulation pipe body 101; the end plate 2011 is provided with a ring of threaded holes; the bellows compensation component 2 also includes: an adjusting flange ring 202, which is fixed to the outside of the corrugated protrusions on the compensation bellows 201 respectively. A fixed adjusting flange ring 202 is fitted; the front adjusting flange ring 202 is fixedly installed on the end plate 2011 by bolts; the compensating bellows 201 is used to seal the well wall surface; the compensating bellows 201 can adapt to the expansion and contraction of the insulation pipe body 101 and maintain the sealing quality, while the cover flange 1031 can protect the outside of the compensating bellows 201 to prevent large stones and other impurities from getting stuck on the compensating bellows 201; this structure utilizes the method of setting the adjusting flange ring 202 on the outside of the corrugated protrusion on the compensating bellows 201, which can make it easier for the staff to quickly... When repairing the compensating bellows 201, if cracks or other defects appear in localized areas due to long-term expansion and contraction, splicing and leak repair can be performed quickly. The operation is simple, reduces repair costs, and is faster. If there are leaks in the compensating bellows 201, a cutting machine can be used to circumferentially cut off the section of the compensating bellows 201 with the leak. The cut end of the compensating bellows 201 can be put back into use by fitting two adjacent adjusting flanges 202 together and connecting them with bolts. The operation is simple and convenient, and there is no need to replace the entire compensating bellows 201.

[0022] The retaining ring connector 3 includes: a first retaining ring 301, which is fixedly installed at the end of the bellows sleeve 102 by bolts; the first retaining ring 301 has a threaded hole for connecting bolts; the retaining ring connector 3 also includes: a second retaining ring 302, the end faces of the second retaining ring 302 and the first retaining ring 301 are coated with rubber; the second retaining ring 302 is fixedly installed at the end of the bellows sleeve 102 by bolts; the two ends of the second retaining ring 302 and the first retaining ring 301 are sealed together; the second retaining ring 302 has a threaded hole for connecting bolts; the first retaining ring 302... The first and second retaining rings 301 and 302 are bolted to the adjusting flange 202 on the same side; the end faces of the second retaining ring 302 and the first retaining ring 301 are flush; the retaining ring connector 3 adopts a two-part structure, which facilitates subsequent disassembly without having to disassemble the already installed insulation pipe body 101. Simultaneously, this structure, in conjunction with the adjusting flange 202, allows for the pre-storage of a section of the compensating corrugated pipe 201 for backup, avoiding the need for complete cutting and replacement of traditional corrugated pipes in case of leakage. By pre-storing a spare section, the service life of this structure can be effectively extended. The replacement of the compensating bellows 201 is faster, eliminating the need for cumbersome cutting and welding. Furthermore, in areas with high groundwater levels and humidity, welding quality can be affected. This structure allows for direct adjustment and use of the new compensating bellows 201, making it more rational and suitable for maintenance operations. The compensating bellows 201 located on the right side of the retaining ring connector 3 is a spare section. When the compensating bellows 201 on the left side of the retaining ring connector 3 expands and contracts to adapt to the insulation pipe body 101, the compensating bellows 201 on the right side of the retaining ring connector 3 will not expand or contract, thus preventing metal fatigue. (The last sentence appears to be incomplete and possibly refers to a different section.) If leakage occurs in the left-side compensating bellows 201, and a portion is cut off, requiring the right-side compensating bellows 201 of the retaining ring connector 3 to extend accordingly for compensation, the bolts connecting the second retaining ring 302, the first retaining ring 301, and the bellows sleeve 102 can be removed. Then, the bolts connecting the second retaining ring 302 and the first retaining ring 301 to the original adjusting flange ring 202 can be removed. At this point, the second retaining ring 302 and the first retaining ring 301 can be removed, and a section of the compensating bellows 201 can be manually pulled outwards. The length pulled out is determined according to the requirements.

[0023] In Embodiment 2, based on Embodiment 1, the outer receiving component 4 includes: an external threaded sleeve 401 and an outer receiving shell 402. The external threaded sleeve 401 is threadedly connected to the outside of the threaded connecting pipe 1021; the outer receiving shell 402 is fixedly sleeved on the external threaded sleeve 401; the outer receiving shell 402 has a through groove; the outer receiving shell 402 is used to receive leakage water between the corrugated pipe sleeve 102 and the well wall surface; the outer receiving component 4 also includes: a sealing washer 403, which is fixedly installed at the end of the outer receiving shell 402. A sealing washer 403 is provided, and the sealing washer 403 is used to fit against the well wall surface; the inner receiving component 5 includes: an inner receiving shell 501 and a drainage ring 502, the inner receiving shell 501 is threadedly connected to the end of the threaded connecting pipe 1021; a gap is provided between the inner ring of the inner receiving shell 501 and the outer ring of the insulation pipe body 101; the drainage ring 502 is fixedly installed on the inner receiving shell 501; the inner receiving shell 501 is used to receive leakage water inside the corrugated pipe sleeve 102; using the outer receiving component 4 and the inner receiving component 5, utilizing Depending on their location, they can be used to collect leakage water between the corrugated pipe sleeve 102 and the well wall, as well as inside the corrugated pipe sleeve 102. This makes it easier for staff to locate the leak, avoiding tedious subsequent inspections and improving maintenance efficiency. Leakage between the corrugated pipe sleeve 102 and the well wall is usually caused by a poor seal between the end of the sleeve flange 1022 and the well wall. Leakage inside the corrugated pipe sleeve 102 is usually caused by a leak in the compensation corrugated pipe 2. 01. Leakage can be easily identified by staff to determine the location requiring repair. Simultaneously, the drainage ring 502 can drain excess water from the inner receiving shell 501 downwards, preventing it from overflowing into the outer receiving shell 402 and causing interference. The sealing gasket 403 is used to adhere to the well wall surface, allowing leakage water flowing from the well wall surface to be collected by the outer receiving shell 402, while leakage water flowing from the corrugated pipe sleeve 102 can be collected by the inner receiving shell 501.

[0024] A method for installing a wall-penetrating sealing structure for thermal insulation pipes: 1) Pass the insulation pipe body 101 through the well wall, and the corrugated pipe sleeve 102 also passes through the well wall; 2) The two covers 103 are fastened to the outside of the insulation pipe body 101 and the two covers 103 are connected by bolts. The cover flange 1031 is attached to the casing flange 1022. Expansion bolts are pre-embedded on the well wall and the casing flange 1022 and cover flange 1031 are fastened to the well wall by the expansion bolts.

[0025] The working principle of this embodiment is as follows: First, when installing the insulation pipe body 101, the corrugated pipe sleeve 102 is first fitted into the insulation pipe body 101, and the end plate 2011 is welded to the outside of the insulation pipe body 101. Then, the insulation pipe body 101 can be passed through the well wall, and the corrugated pipe sleeve 102 also passes through the well wall. The two covers 103 are fastened to the outside of the insulation pipe body 101, and the two covers 103 are connected by bolts. Then, the cover flange 1031 is attached to the sleeve flange 1022, and expansion bolts are pre-embedded on the well wall. Then, the casing flange 1022 and the cover flange 1031 are fastened to the well wall using expansion bolts to perform the sealing installation. Subsequently, the external threaded sleeve 401 is manually threaded onto the threaded connecting pipe 1021, ensuring that the sealing gasket 403 is tightly fitted to the well wall. Finally, the inner bearing shell 501 is manually threaded onto the end of the threaded connecting pipe 1021 to complete the installation of this structure. During maintenance, the staff observe whether there is water accumulation inside the outer bearing shell 402 and the inner bearing shell 501 to determine the location of the leak.

[0026] When leakage occurs in the compensating bellows 201 on the left side of the retaining ring connector 3, and a portion needs to be cut off, requiring a corresponding extension of the compensating bellows 201 on the right side of the retaining ring connector 3 for compensation, the bolts connecting the second retaining ring 302, the first retaining ring 301, and the bellows sleeve 102 can be removed. Then, the bolts connecting the second retaining ring 302 and the first retaining ring 301 to the original adjusting flange ring 202 can be removed. At this point, the second retaining ring 302 and the first retaining ring 301 can be removed, and a section of the compensating bellows 201 can be manually pulled outwards. The length pulled out depends on the requirements. Subsequently, the second retaining ring 302 and the first retaining ring 301 can be installed on the bellows sleeve 102 with bolts. Then, the newly pulled-out adjusting flange ring 202 can be connected to the second retaining ring 302 and the first retaining ring 301 with bolts for tightening and sealing. The operation is simple, and the entire process does not require cumbersome welding operations, thus extending the overall service life of the compensating bellows 201.
