Abstract
Description
Technical Field
[0001] This application belongs to the field of pipe support technology, specifically relating to a pipe wall-penetrating sealing device and sealing structure, which is a device for allowing pipes to pass through walls or partitions. Background Technology
[0002] During pipeline installation, depending on the equipment structure and site requirements, it is often necessary to pass through components or building walls, which will create holes in the walls. In order to ensure the normal operation of the pipeline and prevent dust, moisture, small animals, etc. from the external environment from passing through the wall holes, it is necessary to seal the wall holes.
[0003] Currently, common sealing methods involve filling and sealing with materials such as fireproof putty and sealant. This method has several drawbacks: 1. Fireproof putty and sealant are prone to cracking and aging after a period of use, leading to decreased sealing performance and requiring regular maintenance and replacement, increasing maintenance costs and workload; 2. During pipeline operation, factors such as pipeline expansion and contraction and vibration can easily cause the sealing material to fall off, affecting the sealing effect; 3. The shapes of the holes vary, and the sealing material for each hole may not completely match the material, shape, and color of the wall, affecting aesthetics.
[0004] Therefore, developing a pipe penetration sealing device with good sealing performance, convenient installation, and strong durability is of great practical significance. Utility Model Content

Detailed Implementation
[0029] The present application will be further described below with reference to specific embodiments and accompanying drawings.
[0030] Example 1
[0031] refer to Figures 1-4 As shown, a pipe penetration sealing device includes a first baffle, a second baffle, a first sealing ring 5, a second sealing ring 6, and a pull-out assembly.
[0032] The first and second baffles are respectively installed on both sides of the wall opening to block and seal it, preventing external dust, moisture, small animals, etc. from passing through. Preferably, the first and second baffles are arranged in a horizontally symmetrical manner, which facilitates the processing and manufacturing of the baffles and also facilitates on-site installation and fixing.
[0033] The first baffle includes a first baffle A1 and a first baffle B2 assembled together as a whole plate. The second baffle includes a second baffle A3 and a second baffle B4 assembled together as a whole plate. That is, each baffle includes two individual units, which are assembled into a whole baffle. The individual unit assembly method facilitates on-site operations. The pipe 7 can be passed through the wall hole first, and then the baffle can be installed.
[0034] The inner tube perforations of the first baffle A1 and the first baffle B2 are each provided with a first sealing ring 5, and the inner tube perforations of the second baffle A3 and the second baffle B4 are each provided with a second sealing ring 6. The gap between the pipe 7 and the baffle is sealed and blocked by the first sealing ring 5 and the second sealing ring 6 to ensure the sealing effect.
[0035] A tie rod assembly is provided between the first and second baffles to achieve a fixed connection between them. The tie rod action between the baffles ensures that the baffles are firmly attached to the wall. Mounting holes can also be pre-drilled on the first and second baffles to fix the baffles to the wall with bolts, or the baffles can be directly fixed to the wall with adhesive.
[0036] Both the first and second baffles are rectangular aluminum alloy plates, which possess high strength, rigidity, and durability. The inner perforations on both the first and second baffles are circular; that is, each aluminum alloy plate has a central through-hole matching the outer diameter of the pipe for pipe passage. Both the first sealing ring 5 and the second sealing ring 6 are made of silicone rubber, which is resistant to high temperatures and aging.
[0037] The first baffle A1 and the first baffle B2 are arranged symmetrically, and the second baffle A3 and the second baffle B4 are arranged symmetrically, which facilitates the processing and manufacturing of the baffles and also facilitates on-site installation and fixing.
[0038] The first baffle A1, the first baffle B2, the second baffle A3, and the second baffle B4 all include a flat plate 101 and a boss 102. A boss 102 with a thickness of 4 cm is provided on the inner side of one end face (the end face closest to the wall) of the flat plate 101. The flat plate 101 and the boss 102 are preferably an integral structure. A semi-circular through hole adapted to the outer diameter of the pipe is opened in the middle of the flat plate 101 and the boss 102. The radius of the semi-circular through hole is the pipe radius plus the thickness of the sealing ring.
[0039] The inner tube perforations of the flat plate 101 and the boss 102 together form a sealing groove 103 for mounting a sealing ring. That is, a sealing strip mounting groove is provided on the inner wall of the semi-circular through hole to realize the mounting of the sealing ring. The flat plate 101 and the boss 102 together form a pull hole 104 perpendicular to the plate surface for pull connection between the opposite plates.
[0040] The flat plate 101 is a rectangular plate, and the boss 102 is a rectangular platform. It is necessary to ensure that the outline of the rectangular plate completely covers the wall opening, and that the outline of the boss can be fully accommodated within the wall opening. The sealing groove 103 is a semi-annular groove with a T-shaped cross-section. The first sealing ring 5 and the second sealing ring 6 are both semi-annular rings with a T-shaped cross-section, allowing the sealing rings to be secured within the sealing groove 103. Pull holes 104 are arranged on both sides of the flat plate 101 and the boss 102 to ensure a balanced and reliable pull action.
[0041] Both the first sealing ring 5 and the second sealing ring 6 include a ring body 105, a retaining edge 106, a protrusion 107, and a support rib 108. The ring body 105 has a semi-annular structure, and the two sides of the ring body 105 are provided with an integral retaining edge 106. The retaining edge 106 is engaged in the sealing groove 103 of the baffle, that is, the outer layer of the sealing ring is a retaining strip structure adapted to the retaining groove of the aluminum alloy baffle, so that the sealing ring can be stably engaged on the baffle.
[0042] The inner end face of the ring body 105 is provided with an integrally structured protrusion 107. A cavity is formed within the protrusion 107, which is the part that directly contacts the pipeline. The cavity allows for a good fit between the protrusion 107 and the pipeline. The cavity within the protrusion 107 is divided into two sections on either side by a support rib 108. The support rib 108 is integrally connected within the cavity, ensuring good resilience of the protrusion 107. In other words, the sealing ring adopts a hollow structure with a reinforcing support structure in the middle, ensuring the elasticity and sealing performance of the sealing ring.
[0043] The pull assembly is a pull screw, which passes through the pull hole 104 in the baffle. The pull action of the pull screw is transmitted to the opposite baffles, so that the baffles are tightly attached to the wall, avoiding leaving a large gap that would affect the sealing effect.
[0044] Example 2
[0045] refer to Figures 1-5 As shown, a pipe penetration wall sealing structure includes a wall and a wall hole in the wall, with a pipe 7 passing through the wall hole, and also includes the pipe penetration wall sealing device of Embodiment 1.
[0046] The first and second baffles are respectively positioned on both sides of the wall opening and fixed to the wall in a horizontally symmetrical arrangement to block and seal the sides of the wall opening. The first and second baffles are fixed to the wall by expansion bolts or adhesive. Pipe 7 passes through the pipe perforation on the inner side of the first and second baffles, and also passes through the wall opening, thus allowing pipe 7 to pass through the wall.
[0047] Pipe 7 contacts the first sealing ring 5 and the second sealing ring 6 respectively. The contact and fit of the sealing rings improves the sealing effect and fills the gap between the pipe and the baffle. The first baffle is connected to the second baffle through a pull assembly. The pull assembly realizes the pull connection between the relative baffles to align the two baffles at the initial connection and initially clamp the baffles to the wall.
[0048] The first baffle A1 and the first baffle B2 are arranged parallel to the second baffle A3 and the second baffle B4, meaning that all four baffle units are arranged horizontally or vertically, creating a one-to-one correspondence between the baffle units. The first baffle A1 is connected to the second baffle B4 via a set of tie rods, and the first baffle B2 is connected to the second baffle A3 via another set of tie rods. This method of installation is relatively simple and quick.
[0049] Alternatively, the first baffle A1 and the first baffle B2 can be arranged perpendicularly to the second baffle A3 and the second baffle B4. That is, the two baffle units of the first baffle are arranged horizontally, while the two baffle units of the second baffle are arranged vertically, creating a one-to-two correspondence between the baffle units. The first baffle A1 is then connected to the second baffle A3 and the second baffle B4 via a set of tie-down components, and the first baffle B2 is connected to the second baffle A3 and the second baffle B4 via another set of tie-down components. This method is relatively complex to install, but the one baffle unit corresponding to two baffle units improves the assembly effect between the baffles.
[0050] Because GIL (Gas Insulated Metal Enclosed Transmission Line) has advantages such as large transmission capacity, low loss, and insensitivity to environmental factors, it is widely used. Therefore, pipeline 7 is preferably a GIL pipeline. Similarly, pipeline 7 can also be other water or gas supply pipelines.
[0051] The workflow of this application is as follows: Assemble four sets of aluminum alloy baffles with installed sealing rings to complete the pipe penetration sealing device assembly. Install two sets of baffles on both sides of the wall opening, with positioning and fixing holes on the baffles ensuring alignment and fixation. Secure the baffles to the wall using adhesive or expansion bolts to complete the installation.
[0052] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.
[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
