Description

Technical Field

[0001] The utility model relates to the technical field of building equipment, and more specifically to a sound-absorbing wall-penetrating pipe for building water supply and drainage. Background Art

[0002] Wall-penetrating sleeve is also called wall-penetrating pipe, waterproof sleeve, wall embedded pipe. Waterproof sleeve is divided into rigid waterproof sleeve and flexible waterproof sleeve. The two are mainly used in different places. Flexible waterproof sleeve is mainly used in civil defense walls, pools and other places with high requirements. Rigid waterproof sleeve is generally used in basements and other places where pipes need to be passed through. Wall-penetrating pipes are used in building water supply and drainage to guide and discharge water flow. Wall-penetrating sleeves are often affected by the vibration of water supply and drainage pipes and generate noise, which will cause great noise pollution in the building. Therefore, a sound-absorbing wall-penetrating pipe for building water supply and drainage is needed.

[0003] The existing design of wall-penetrating pipes for building water supply and drainage is relatively traditional. When water is discharged through the wall-penetrating pipes in building water supply and drainage, it is easy to generate large noise inside the pipes when water flows through the inside of the pipes. The noise is transmitted through the walls, and the inside of the pipes has insufficient noise-absorbing capacity to reduce the impact of noise pollution from water supply and drainage pipes on buildings.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sound-absorbing wall-penetrating pipe for building water supply and drainage comprises an outer sleeve, an inner sleeve is arranged inside the outer sleeve, the shape of the inner sleeve is set to be a circular tube, a sound-absorbing mechanism is arranged outside the inner sleeve, the sound-absorbing mechanism comprises two shock-absorbing sleeves sleeved outside the inner sleeve, the two shock-absorbing sleeves are sleeved outside with a fixed sleeve, the shock-absorbing sleeves and the fixed sleeves are arranged inside with sound-absorbing cotton, the inner wall of the outer sleeve is provided with a plurality of slots, the interiors of the plurality of slots are provided with sound insulation layers, a shock absorber is arranged on one side of the fixed sleeve, one side of the shock absorber is connected to the slot, and the inner walls of the outer sleeve and the inner sleeve are provided with sound-absorbing cotton. The above technical scheme is adopted to improve the sound-absorbing effect of the device.

[0007] As a further description of the above technical solution: flanges are provided at both ends of the outer sleeve, a sealing gasket is provided between the flange and the outer sleeve, a plurality of bolts are provided on the surface of the flange, the outer sleeve and the flange are both made of stainless steel, the shock-absorbing sleeve is made of plastic foam material, and the fixing sleeve is made of stainless steel. The above technical solution is adopted to increase the stability of the installation of the device.

[0008] Technical effects and advantages of the utility model:

[0009] 1. By setting up the silencing mechanism and the coordinated use of the silencing cotton, compared with the prior art, when the device vibrates and needs to be silenced, the sound-absorbing cotton on the inner wall of the outer sleeve and the inner sleeve is used for initial sound absorption. The shock-absorbing sleeve made of plastic foam can play a good buffering and silencing role. In addition, the buffering and silencing effect of the shock absorber can minimize the impact of noise on the building. When the shock absorber is connected to the card slot of the outer sleeve, the noise generated between the shock absorber and the outer sleeve can be reduced by the sound insulation layer inside the card slot, so that the device has excellent silencing function, which can effectively reduce the impact of noise pollution from water supply and drainage pipes on buildings;

[0010] 2. By setting up the coordinated use of sealing gaskets, flanges and bolts, compared with the prior art, during installation, the outer sleeve can be first passed through the reserved holes in the wall, and then flanges can be welded at both ends of the outer sleeve, and then the flanges can be fixed to the wall by bolts passing through the mounting holes. The sealing gasket set at the outer sleeve can increase the sealing of the device. Through this fixing method, the outer sleeve can be fixed to the wall to prevent the device from falling, thereby increasing the stability of the installation. BRIEF DESCRIPTION OF THE DRAWINGS
