Description

Technical Field

[0001] This utility model relates to the field of gas pipeline technology, and in particular to a through-wall anti-corrosion gas pipe with a locking sleeve structure and its installation structure. Background Technology

[0002] With the widespread use of natural gas in residential and industrial production, the safety and reliability of gas transmission pipelines have become increasingly important. During the laying of gas pipelines, it is often necessary to pass through structures such as walls.

[0003] Traditional gas pipes penetrating walls have many problems, mainly three: Corrosion issues: When ordinary metal gas pipes pass through walls, the complex internal environment of the walls, which may contain moisture, acid and alkali substances, can easily cause corrosion to the gas pipes, reduce the service life of the pipes, and increase the risk of gas leaks.

[0004] Secondly, there is the issue of sealing: the existing sealing structure between the wall sleeve and the gas pipe is often inadequate, failing to effectively prevent the entry of external moisture and impurities, further exacerbating the corrosion of the gas pipe and potentially leading to gas leaks, threatening life and property safety. In some cases, the sealing material in the wall sleeve ages and fails after a period of use, significantly reducing its sealing performance.

[0005] Third, relocation issues: Common problems during construction or homeowner renovation include unsecured pipe sleeves, insufficient length, and relocation, which seriously affect the aesthetics and lifespan of the pipes. This causes numerous inconveniences for later rectification and incurs significant time and labor costs.

[0006] Therefore, it is necessary to design a reasonable gas pipe structure to solve the above problems. Utility Model Content

[0007] To address the aforementioned problems, this utility model provides a through-wall corrosion-resistant gas pipe with a locking sleeve structure and its installation structure, thereby solving the problems of corrosion, poor sealing, inconvenient installation, and displacement of ordinary sleeves in existing gas through-wall pipes.

[0008] The technical solution of this utility model is as follows: A through-wall corrosion-resistant gas pipe with a locking sleeve structure includes a gas pipe, the gas pipe being fitted with a locking sleeve, the locking sleeve including a through-wall sleeve, the through-wall sleeve having a left end cap and a right end cap screwed onto both ends to fit the wall, the gas pipe being covered with a left sealing plug and a right sealing plug that slide at intervals, the left sealing plug and the right sealing plug being inserted into the inner wall of the through-wall sleeve.

[0009] Furthermore, the thread length of the left section of the through-wall sleeve is greater than the thread length of the right section.

[0010] Furthermore, the through-wall sleeve, left end cap, and right end cap are made of plastic.

[0011] Furthermore, the left and right sealing plugs have the same structure, with an axial cross-section in the shape of a T and a radial cross-section in the shape of a C. The main body is cylindrical, with an annular limiting boss on the outer wall near the end of the cylinder, and an opening along the generatrix direction.

[0012] Furthermore, the system includes a wall with an external wall insulation layer. The wall and the external wall insulation layer have a horizontal through-hole at the gas installation inlet. A through-wall sleeve is installed through the through-hole, with both ends extending out. An external sealant layer fills the space between the through-wall sleeve and the through-hole. Left and right end caps with the external sealant layer are screwed onto the extended ends of the through-wall sleeve. The gas pipe passes through the through-wall sleeve, with both ends extending out. An internal sealant layer fills the space between the gas pipe and the through-wall sleeve. Left and right sealing plugs with the internal sealant layer are fitted onto the extended ends of the gas pipe.

[0013] Furthermore, after the left and right sealing plugs are installed, the cylinder section is inserted into the gap between the wall sleeve and the gas pipe, and the limiting boss is tightly attached to the end of the wall sleeve, with the outer diameter of the limiting boss being the same as the size of the wall sleeve.

[0014] Furthermore, protective sealing rings are added between the left end cover and the wall, and between the right end cover and the external wall insulation layer.

[0015] Furthermore, the outer and inner sealing layers are sealed with sealant, which is a sealing material with good adhesion, flexibility and waterproof performance.

[0016] The beneficial effects of this utility model are as follows: 1. This utility model uses a tight-fitting sleeve. The wall sleeve is made of non-metallic anti-corrosion material or metal material that has been treated with anti-corrosion. This avoids the complex environment inside the wall. Even if there is water vapor, acid and alkali substances, it reduces the corrosion of the gas pipe, improves the service life of the pipeline, and reduces the risk of gas leakage. The procurement cost is significantly lower than that of using steel sleeves.

[0017] 2. This utility model adopts a tight-fitting sleeve in conjunction with an outer sealing layer to ensure the seal between the wall-penetrating sleeve and the gas pipe, effectively preventing external moisture and impurities from entering and reducing corrosion of the gas pipe. The working section of the wall-penetrating sleeve and the outer sealing layer are located inside the wall-penetrating hole, so the sealing material is not prone to aging and failure, and the sealing performance is improved.

[0018] 3. This utility model adopts a tight-fitting sleeve during construction or homeowner decoration. The sleeve is easy to fix. The wall sleeve has a left end cap and a right end cap that fit the wall at both ends. By adjusting the left end cap and the right end cap, the effective length can be dynamically adjusted according to the actual thickness of the wall (including the internal decorative layer), adapting to different wall penetration conditions and solving the problems of inconvenient installation and displacement of ordinary sleeves.

[0019] 4. After the wall sleeve of this utility model is filled with an inner sealing adhesive layer between it and the gas pipe, it further prevents external moisture and impurities from entering, reduces corrosion to the gas pipe, and improves the sealing performance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] A wall-penetrating anti-corrosion gas pipe with a locking sleeve structure includes a gas pipe 1, and a locking sleeve is fitted around the gas pipe 1. The locking sleeve includes a wall-penetrating sleeve 2. The wall-penetrating sleeve 2 is screwed with a left end cap 3 and a right end cap 4 that cooperate with the wall from both ends. The gas pipe 1 is covered with a left sealing plug 5 and a right sealing plug 6 that slide at intervals. When working, the left sealing plug 5 and the right sealing plug 6 are inserted into the inner wall of the wall-penetrating sleeve 2.

[0025] Furthermore, the length of the thread 2-1 on the outer wall of the left section of the through-wall sleeve 2 is greater than the length of the thread 2-2 on the outer wall of the right section. Generally, there is also internal decoration inside the wall. The thread on the outer wall of the left section of the through-wall sleeve 2 is adjusted in conjunction with the left end cap 3 to adapt to different through-wall working conditions. It is easy to install and fix and is not easy to move.

[0026] Furthermore, the left sealing plug 5 and the right sealing plug 6 have the same structure, with an axial cross-section in the shape of a T and a radial cross-section in the shape of a C. The main body is cylindrical. The outer wall of the cylindrical body 5-1 near the end is provided with an annular limiting boss 5-2. The cylindrical body 5-1 is provided with an opening 5-3 along the generatrix direction. It is made of flexible silicone material. During installation, it is fitted and wrapped around the gas pipe 1 from the opening end and slid along the gas pipe 1 into the inner wall of the through-wall sleeve 2.

[0027] Furthermore, the system includes a wall 7, with an external wall insulation layer 8 installed on the outside of the wall 7. The wall 7 and the external wall insulation layer 8 are provided with a horizontal through-wall hole at the gas installation inlet. A through-wall sleeve 2 is installed through the through-wall hole, with both ends of the through-wall sleeve 2 extending outwards. An external sealant layer 9 is filled between the through-wall sleeve 2 and the through-wall hole. A left end cap 3 and a right end cap 4, which plug the external sealant layer 9, are screwed onto the extended sections of the through-wall sleeve 9. A gas pipe 1 passes through the through-wall sleeve 2, with both ends of the gas pipe 1 extending outwards. An internal sealant layer 10 is filled between the gas pipe 1 and the through-wall sleeve 2. A left sealing plug 5 and a right sealing plug 6, which plug the internal sealant layer, are fitted onto the extended sections of the gas pipe 1.

[0028] Furthermore, after the left sealing plug 5 and the right sealing plug 6 are installed, the cylinder section is inserted into the gap between the wall sleeve 2 and the gas pipe 1, and the limiting boss 5-2 is tightly attached to the end of the wall sleeve 2. The outer diameter of the limiting boss 5-2 is the same as that of the wall sleeve 2.

[0029] Furthermore, protective sealing rings 11 are added between the left end cover 3 and the wall 7, and between the right end cover 4 and the external wall insulation layer 8, which can further improve the fit between the wall 7, the external wall insulation layer 8, and the through-wall sleeve 2. The left end cover 3 and the right end cover 4 firmly fix the sleeve to the wall (or embed it in the wall or the external wall insulation layer) to prevent it from shaking and shifting.

[0030] Furthermore, the outer sealing layer 9 and the inner sealing layer 10 are sealed with sealant.

[0031] When gas is transported through a gas pipe, the wall-penetrating sleeve 2 acts as an external protective layer, isolating the gas pipe from moisture, acids, alkalis, and other substances in the wall. The left end cap 3, right end cap 4, and sealing layers (outer sealing layer 9, inner sealing layer 10) work together to prevent external substances from entering the gap between the wall-penetrating sleeve 2 and the gas pipe, keeping the inside of the gas pipe 1 clean and dry. The left end cap 3 and right end cap 4 firmly fix the sleeve to the wall (or embed it in the wall or external wall insulation layer), preventing it from shaking or shifting.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
