Description

Technical Field

[0001] The invention belongs to the technical field of wall-penetrating pipes, and in particular relates to a sound-absorbing wall-penetrating pipe for building water supply and drainage. Background Art

[0002] Currently, when installing wall-penetrating pipes, they are mostly directly cast and installed inside the wall. This allows the water pipes to be laid concealed through the wall. It is widely used in scenes such as stages, studios, and cinemas. While increasing the aesthetics, it also greatly reduces the installation and connection steps of the water pipes.

[0003] However, since the through-wall pipe is directly buried inside the wall, when the concrete is poured, there are no obstructions on both sides, so it is very easy for a small amount of concrete to enter the pipe and solidify. As a result, impurities in the water flow are easily hung on the solidified concrete during later use. As time goes by, the problem of impurity accumulation occurs. In addition, when the pipe is damaged in the later stage, it is often necessary to demolish a small part of the wall before the pipe can be dismantled due to the casting and fixation. In addition, the through-wall pipe is cast in the wall, so that the outer periphery cannot be wrapped with attracting cotton, resulting in greater water flow noise when the water flows through. In addition, the casting and fixed installation of the through-wall pipe forces it to be unable to vibrate, which allows the water flow to drive the connected water pipe to vibrate while the through-wall pipe cannot vibrate synchronously, resulting in the connection being prone to leakage after long-term use.

[0010] Preferably, a glass wool tube is wrapped on the outer wall of the inner tube, the outer wall of the glass wool tube is in contact with the inner wall of the outer tube, a plurality of storage grooves are symmetrically opened at equal intervals on the inner ring of the glass wool tube, and the interior of the storage grooves is filled with melt water particles.

[0011] Preferably, a sealing ring is fixedly mounted on one side of the positioning plate close to the end of the outer tube, the sealing ring is in contact with the end surface of the outer tube, and the sealing ring is used to fill the gap between the positioning plate and the end of the outer tube.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 2 and Figure 4-Figure 5 As shown, the present invention provides the following technical solutions: a sound-absorbing wall-penetrating pipe for building water supply and drainage comprises an outer pipe 4, the outer pipe 4 is H-shaped, and an inner pipe 6 is arranged inside the outer pipe 4, the length of the inner pipe 6 is greater than the length of the outer pipe 4, and the outer wall of the inner pipe 6 near both ends thereof is symmetrically provided with connecting grooves 17, a positioning plate 8 is fixedly installed on the connecting groove 17, the diameter of the positioning plate 8 is the same as the end diameter of the outer pipe 4, and the positioning plate 8 is in contact with the end face of the outer pipe 4, and the outer ring of the positioning plate 8 and the end of the outer pipe 4 is provided with threads Groove 24, and the outer periphery of the positioning disk 8 and the end of the outer tube 4 is covered with a U-shaped connecting cover 7, the inner wall of the connecting cover 7 is provided with a second thread 3, the positioning disk 8 and the end of the outer tube 4 are fixedly connected with the connecting cover 7 through the threaded connection of the second thread 3 and the thread groove 24, a connecting hole 21 is provided on the positioning disk 8, a spiral groove 22 is provided on the inner wall of the connecting hole 21, a first thread 2 is provided on the side of the connecting groove 17 close to the inner tube 6, and the positioning disk 8 is fixedly connected with the inner tube 6 through the threaded connection of the first thread 2 and the spiral groove 22.

[0024] Through the above technical solution: during installation, the outer tube 4 is first cast and installed inside the wall, and then the inner tube 6 is penetrated and installed inside the outer tube 4, and the two positioning plates 8 are sleeved on the connecting grooves 17 at both ends of the inner tube 6, and the positioning plates 8 are fixed to the two ends of the inner tube 6 through the spiral connection between the spiral groove 22 and the first thread 2. At this time, the side walls of the positioning plates 8 and the side walls of the outer tube 4 are in contact with each other, and the inner tube 6 is fixedly set inside the outer tube 4 by using the two positioning plates 8 to force it to be unable to slide, and then the two connecting covers 7 are screwed on the ends of the outer tube 4, and the inner tube 6 is fixedly set inside the outer tube 4 by using the two positioning plates 8. The second thread 3 and the thread groove 24 are threadedly connected, and the outer tube 4 and the inner tube 6 are fixedly connected through the positioning plate 8 and the connecting cover 7, so that the fixed installation of the wall-penetrating tube is completed. The entire installation procedure is relatively simple. At the same time, since the inner tube 6 is not directly connected to the wall, and the inner wall of the outer tube 4 is not in direct contact with the water flow, when repairing or replacing the wall-penetrating tube, it is only necessary to remove the connecting cover 7 and the positioning plate 8 one by one in sequence and pull out the inner tube 6 inside the outer tube 4. There is no need to dismantle the wall and the outer tube 4, which simplifies the steps and costs when replacing damaged pipes.

[0025] In addition, since the connecting cover 7 and the positioning plate 8 fix the outer tube 4 and the inner tube 6 together, the inner tube 6 is prevented from frequently shaking up and down under the influence of the impact force of the water flow when the water flow impacts the inner tube 6, thereby preventing the occurrence of noise.

[0026] Furthermore, a through hole 18 is provided at the center of the side of the connecting cover 7 away from the inner tube 6, and a connecting water pipe 10 is penetrated in the through hole 18. The end of the connecting water pipe 10 is T-shaped, and the end of the connecting water pipe 10 is sleeved on the connecting groove 17. Through holes 19 are symmetrically provided on the T-shaped end of the connecting water pipe 10. Bolts 14 are symmetrically installed on the side of the positioning plate 8 away from the inner tube 6. The bolts 14 are located inside the through hole 18, and the bolts 14 are penetrated through the through holes 19 on the end of the connecting water pipe 10. A nut 11 is fixed on the bolt 14, and the side wall of the nut 11 is in contact with the end of the connecting water pipe 10.

[0027] Please refer to Figure 1-Figure 2 and Figure 4 Since the connection cover 7 is provided with a through hole 18, the connecting water pipe 10 needs to be embedded in the through hole 18 during installation, and the bolt 14 needs to be passed through the through hole 19 and set on the end of the connecting water pipe 10. At this time, the nut 11 is fixedly installed on the bolt 14 to complete the installation of the connecting water pipe 10. Since the end of the connecting water pipe 10 is engaged with the through hole 18 and is indirectly fixedly connected to the outer pipe 4 cast inside the wall, the end of the connecting water pipe 10 is prevented from vibrating under the influence of water flow, thereby preventing the sealing connection between the connecting water pipe 10 and the inner pipe 6 from gradually decreasing under the influence of vibration.

[0028] Furthermore, a rubber ring 1 is wrapped on one side of the connecting groove 17 away from the outer tube 4, the thickness of the rubber ring 1 is less than the thickness of the first thread 2, and a waterproof sealant 16 is adhered and fixed on the outer ring of the rubber ring 1, the waterproof sealant 16 is in contact with the inner wall of the connecting water pipe 10, a guide groove 9 is provided on the inner wall of the inner tube 6 near its water inlet end, the inner wall of the guide groove 9 is inclined inward, a baffle 12 is provided at the central bottom of the inner wall of the inner tube 6, the baffle 12 is triangular, and a water groove 15 is provided in the middle of the baffle 12, and the water groove 15 is V-shaped.

[0029] Please refer to Figure 1-Figure 2 and Figure 4Before installing the connecting water pipe 10, the seal of the waterproof sealant 16 needs to be torn off, and then the connecting water pipe 10 is sleeved on the rubber ring 1, and the rubber ring 1 and the waterproof sealant 16 are used to increase the connection sealing of the inner tube 6 and the connecting water pipe 10, and the possibility of water leakage is reduced in conjunction with the connecting cover 7. The opening of the guide groove 9 makes it necessary for the water flow to pass through the obstruction of the inclined surface of the guide groove 9 when entering the inner tube 6 from the connecting water pipe 10. While increasing the connection sealing in conjunction with the rubber ring 1 and the waterproof sealant 16, the water flow is preliminarily reduced in velocity before entering the inner tube 6. The reduction in the water flow velocity can effectively reduce the existence of water in the inner tube 6. The bubbles in the water flow are eliminated on the inclined surface of the baffle block 12, thereby achieving the purpose of silencing. When the water flows through the inner tube 6, it contacts the inclined surface of the baffle block 12 due to the influence of inertia, and gradually accumulates on the inclined surface of the baffle block 12, and finally passes through the baffle block 12 through the water groove 15 between the baffle blocks 12 to continue to flow, which slows down the water flow speed for the second time, and makes the bubbles in the water flow be eliminated on the inclined surface of the baffle block 12, and then cooperates with the guide groove 9 to achieve the effect of silencing and noise reduction, minimizes the noise generated inside the inner tube 6, and eliminates the problem of high noise when the water flows through due to the wall-penetrating pipe being cast in concrete and unable to wrap the attraction cotton.

[0030] Furthermore, a glass wool tube 5 is wrapped on the outer wall of the inner tube 6, and the outer wall of the glass wool tube 5 is in contact with the inner wall of the outer tube 4. A plurality of storage grooves 25 are symmetrically arranged at equal intervals on the inner ring of the glass wool tube 5, and the interior of the storage grooves 25 is filled with melt water particles 26. A sealing ring 13 is fixedly installed on one side of the positioning plate 8 close to the end of the outer tube 4, and the sealing ring 13 is in contact with the end face of the outer tube 4, and the sealing ring 13 is used to fill the gap between the positioning plate 8 and the end of the outer tube 4.

[0031] Please refer to Figure 1 Since the outer periphery of the inner tube 6 is wrapped with the glass wool tube 5, when the inner tube 6 is penetrated and installed, the outer wall of the inner tube 6 and the inner wall of the outer tube 4 are blocked by the glass wool tube 5 and will not be rubbed, thus eliminating the problem of friction damage between the inner tube 6 and the outer tube 4 during installation. At the same time, the wrapped glass wool tube 5 not only slows down the change of the pipeline temperature, but also reduces the impact of thermal expansion and contraction on the inner tube 6 in winter, and can also absorb part of the noise of the water flow inside the inner tube 6, and cooperate with the flow block 12 inside the inner tube 6 to achieve a silencing effect.

[0032] In addition, if the inner tube 6 is damaged, the leaked water will directly come into contact with the melted water particles 26 inside the storage tank 25, and then change the color of a portion of the glass wool tube 5 through the melted water particles 26. Subsequent maintenance personnel only need to observe whether the glass wool tube 5 changes color to determine whether the inner tube 6 is damaged or quickly lock the damaged position.

[0033] See also Figure 1-Figure 4As shown, plastic sheets 23 are symmetrically installed at equal intervals on the inner wall of the through hole 18 on the connecting cover 7, and a partition plate 20 is fixedly connected to the end of the plastic sheet 23, and the partition plate 20 is used to control the opening and closing of the through hole 18.

[0034] Please refer to Figure 3 Before pouring and installing the outer tube 4, the operator needs to screw the two connecting covers 7 on both ends of the outer tube 4, and fix them by the screw connection of the second thread 3 and the connecting groove 17. The two ends of the outer tube 4 are blocked by the connecting covers 7 and the spacer 20 to prevent a small amount of concrete from entering the outer tube 4 during concrete pouring. This prevents the problem that a small amount of concrete can easily enter the pipe and solidify due to the lack of obstacles on both sides during concrete pouring, making it impossible for the inner tube 6 to enter.

[0035] When installing the inner tube 6, the operator needs to first rotate the connecting cover 7 and remove the two connecting covers 7 from the two ends of the outer tube 4. After the inner tube 6 and the positioning plate 8 are installed, the connecting cover 7 is screwed back on the end of the outer tube 4, and an outward pulling force is applied to the partition plate 20 through the gap between the connecting cover 7 and the partition plate 20, causing the plastic sheet 23 to break and force the partition plate 20 to detach from the inside of the through hole 18, thereby opening the through hole 18 to pave the way for the subsequent installation of the connecting water pipe 10.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
