Description

Technical Field

[0001] The utility model relates to the technical field of pipeline anti-leakage, in particular to a plugging device for a heat pipe passing through a wall in a heat well chamber. Background Art

[0002] At present, when a heat pipeline passes through a wall and enters a well chamber, if there is no proper sealing measure, the waterproof layer around the wall-piercing hole is likely to be damaged due to reasons such as thermal expansion and contraction, vibration or improper installation, resulting in water leakage. This not only affects the thermal efficiency of the pipeline, but also may cause damage to the wall structure and the surrounding environment.

[0003] Currently, the existing sealing methods for wall-piercing pipelines often cannot completely prevent water leakage. Especially in a heat well chamber, due to the large temperature difference between the inside and outside and frequent thermal expansion and contraction, the sealing between the wall and the pipeline is not tight, resulting in frequent water leakage. This not only wastes water resources, but also causes wall erosion and reduces structural safety. Specifically, the commonly used glue injection sealing method in the prior art depends on the physical and chemical properties of the sealant. When in a high-temperature environment for a long time, the sealant is prone to aging, hardening and cracking, losing the sealing effect. In addition, the glue injection process requires waiting for the colloid to solidify, which prolongs the construction period and increases the construction cost. Moreover, the differences in the quality of the colloid and the construction process will affect the reliability and durability of the seal.

[0004] Therefore, a plugging device for a heat pipe passing through a wall in a heat well chamber is needed to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a plugging device for a heat pipe passing through a wall in a heat well chamber. Through the multi-layer sealing design of the first seal, the second seal and the third seal, the utility model ensures a tight seal between the wall and the pipeline, effectively solving the water leakage problem caused by poor sealing in the heat pipeline passing through the well chamber. This not only avoids the waste of water resources, but also prevents the wall and the foundation structure from being eroded by water, and prolongs the service life of the building and the pipeline.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a plugging device for a heat pipe passing through a wall in a heat well chamber, including a sealing device, and the sealing device is installed between the inner wall of the wall and the outer protection pipe;

[0007] The sealing device includes expansion bolts, a first flange gland, a second flange gland, a first seal, a second seal and a third seal;

[0008] One end of the expansion bolt is fixedly connected inside the wall. The first flange gland and the second flange gland are both fixedly connected to the expansion bolt. The first seal is installed between the first flange gland and the inner wall. The second flange gland is arranged on one side of the first flange gland. The second seal is fixedly connected to the first flange gland. The third seal is installed between the second seal and the second flange gland.

[0009] Furthermore, a first baffle is fixedly connected to the side of the second flange gland close to the first flange gland. A first top plate is fixedly connected to the lower end of the first baffle. The first top plate contacts the third seal and presses the third seal and the second seal tightly against each other.

[0010] Furthermore, a second baffle is fixedly connected to the side of the first flange gland close to the inner wall. A second top plate is fixedly connected to the lower end of the second baffle. The second top plate contacts the first seal.

[0011] Furthermore, gaps are left between the first flange gland and the outer protection pipe, and between the second flange gland and the outer protection pipe.

[0012] Furthermore, the first flange gland and the expansion bolt are mutually limited and fixed by a first limit nut, and the second flange gland and the expansion bolt are mutually limited and fixed by a second limit nut.

[0013] Furthermore, both the first flange gland and the second flange gland are made of Q235 steel.

[0014] Furthermore, the first seal, the second seal and the third seal are all elastic non-metallic parts.

[0015] The advantages of the present utility model are as follows:

[0016] 1. Effectively waterproof and prevent leakage: Through the multi-layer sealing design of the first seal, the second seal and the third seal, the strict sealing between the wall and the pipeline is ensured, effectively solving the water leakage problem caused by poor sealing in the heat pipeline through-wall shaft. This not only avoids the waste of water resources, but also prevents the moisture from eroding the wall and the foundation structure, and prolongs the service life of the building and the pipeline.

[0017] 2. Protect the insulation layer and maintain the pipeline efficiency: This device does not need to damage the insulation layer of the insulated pipeline for installation, avoiding the water leakage phenomenon and the carbonization failure of the polyurethane material caused by the damage of the insulation layer, thus ensuring the insulation performance of the pipeline, reducing the heat loss, and improving the overall energy efficiency of the heat system.

[0018] 3. Avoid heat conduction damage: Through the non-direct contact design between steel components (such as the first flange gland and the second flange gland) and the working pipe, the heat conduction path is isolated, protecting the wall and non-steel components from the high temperature of the thermal pipeline, reducing heat loss and potential safety hazards.

[0019] 4. Adapt to pipeline displacement and prevent structural damage: Since there is a gap reserved between the first flange gland, the second flange gland and the outer protection pipe, it allows the pipeline to naturally expand and contract with temperature changes without causing extrusion or tensile damage to the leak stoppage device itself, enhancing the stability and durability of the device.

[0020] 5. Simplify construction and improve efficiency: Compared with the traditional glue injection sealing method, this device adopts a combined component form, eliminating the need to wait for the sealant to cure, greatly simplifying the installation process, shortening the construction time and reducing the labor cost. At the same time, it avoids the problem of sealant aging and failure due to long-term high temperature, ensuring the durability of the leak stoppage effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1:

[0035] Figure 1 It is a schematic assembly structure diagram of the present utility model. Figure 2 It is an enlarged structural schematic diagram of the sealing device in the present utility model. As Figure 1 shown in Figure 2 the heat well chamber wall-piercing pipeline leakage plugging device, which includes a sealing device 5. The sealing device 5 is installed between the inner wall 302 of the wall 3 and the outer protection pipe 2.

[0036] The sealing device 5 in the present utility model includes an expansion bolt 501, a first flange gland 502, a second flange gland 503, a first seal 504, a second seal 505 and a third seal 506; one end of the expansion bolt 501 is fixedly connected inside the wall body 3. The expansion bolt 501 serves as the fixed foundation of the entire leak plugging device. One end of it is fixed inside the wall body 3, providing a stable support point, ensuring that the device is stable and does not shift, and being able to withstand various stresses during the operation of the pipeline; both the first flange gland 502 and the second flange gland 503 are fixedly connected to the expansion bolt 501. The first flange gland 502 and the second flange gland 503 together constitute the core framework of the sealing structure. By being fixed to the expansion bolt 501, they not only provide an installation platform for multiple seals, but also can achieve precise limiting through the limit nut, ensuring the pressure balance of multiple seals in different directions, thereby enhancing the sealing effect.

[0037] The first seal 504 in the present utility model is installed between the first flange gland 502 and the inner wall 302. By the first seal 504, the possible gap between the wall body 3 and the pipeline is directly blocked, preventing water from seeping from one side of the wall body 3, playing a basic waterproof barrier role. The second flange gland 503 is arranged on one side of the first flange gland 502. The second seal 505 is fixedly connected to the first flange gland 502. The second seal 505 further strengthens the sealing effect of the middle part; the third seal 506 is installed between the second seal 505 and the second flange gland. The third seal 506 is installed between the second seal 505 and the second flange gland 503 and interacts with the first top plate 507 to form a more airtight sealing layer, ensuring a good sealing state even under extreme working conditions.

[0038] In the present utility model, a first baffle 508 is fixedly connected to the side of the second flange gland 503 close to the first flange gland 502. A first top plate 507 is fixedly connected to the lower end of the first baffle 508. The first top plate 507 is in contact with the third seal 506 and presses the third seal 506 and the second seal 505 tightly together. This combination of the first baffle 508 and the first top plate 507 increases the reliability of the seal by tightly pressing the third seal 506 and the second seal 505 together, especially playing an important role in preventing the tiny gaps caused by thermal expansion and contraction, and improving the overall waterproof performance.

[0039] On one side of the first flange gland 502 close to the inner wall 302 of the utility model, a second baffle 510 is fixedly connected. At the lower end of the second baffle 510, a second top plate 509 is fixedly connected. The second top plate 509 is in contact with the first seal 504. Similarly, the combination of the second baffle 510 and the second top plate 509 enhances the seal on the side of the wall 3 by directly contacting the first seal 504, preventing water from penetrating in this direction and protecting the thermal insulation layer 4 from being squeezed.

[0040] In the utility model, a gap is left between the first flange gland 502 and the outer protection tube 2, and between the second flange gland 503 and the outer protection tube 2. The pipeline provides necessary space for thermal expansion and contraction, avoiding seal damage caused by pipeline displacement, and increasing the flexibility and durability of the device.

[0041] In the utility model, the first flange gland 502 and the expansion bolt 501 are mutually limited and fixed by a first limit nut 511, and the second flange gland 503 and the expansion bolt 501 are mutually limited and fixed by a second limit nut 512. The first limit nut 511 and the second limit nut 512 are respectively used to limit the positions of the first flange gland 502 and the second flange gland 503. Through precise adjustment, it can ensure that while applying appropriate pressure to the whole device, the correct alignment between components is maintained, improving the overall stability and seal reliability.

[0042] Both the first flange gland 502 and the second flange gland 503 in the utility model are made of Q235 steel, ensuring structural strength and corrosion resistance; the first seal 504, the second seal 505 and the third seal 506 are all elastic non-metallic parts, which can not only effectively seal but also adapt to the minor deformation of the pipeline, improving the adaptability and reliability of the whole device.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
