Description

Technical Field

[0001] The present application relates to the technical field of wall-piercing pipelines, and particularly to a wall-piercing node for a heat-insulating air duct or water pipe. Background Art

[0002] A wall-piercing pipeline refers to a pipeline installed in a building that needs to pass through a wall to achieve fluid transportation or other functional connections between different spaces. It is usually made of metal (such as steel pipes, cast iron pipes, etc.), plastic (such as PVC pipes, PE pipes, etc.) or other materials. Different materials of pipelines have different characteristics and are suitable for different application scenarios.

[0003] Wall-piercing pipelines will generate certain noises during the process of transporting gas and liquid, which may interfere with the indoor environment. For some noise-sensitive places, it affects people's life and work. At the same time, due to the influence of the position of the pipeline part inside the wall, the low-temperature resistance and heat-insulating effect of the wall-piercing pipeline are insufficient. Therefore, it is necessary to provide a wall-piercing node for a heat-insulating air duct or water pipe, which adopts a double treatment process of heat insulation and sound absorption to effectively improve the low-temperature resistance and heat-insulating effect of the pipeline, effectively suppress the noise, and at the same time adopts a double-sided clamping plate structure to reinforce and cover the wall-piercing pipeline and the wall position, improving the stability of the wall-piercing pipeline and the aesthetic degree of the connection position.

[0030] Embodiment 1:

[0031] Combined with Figures 1-4 , an embodiment of the present application discloses a heat-insulating air duct or water pipe wall-piercing node, which includes a pre-embedded pipe sleeve 1 penetrating the wall. The surface of the pre-embedded pipe sleeve 1 is filled with cement mortar 8, and the cement mortar 8 evenly wraps the surface of the pre-embedded pipe sleeve 1. A wall-piercing pipe 2 is inserted into the inner cavity of the pre-embedded pipe sleeve 1. An acoustic absorption layer 3 is arranged in the inner cavity of the pre-embedded pipe sleeve 1. Three anti-displacement plates 7 fixedly connected thereto are annularly distributed on both sides of the pre-embedded pipe sleeve 1. Both sides of the acoustic absorption layer 3 are in close contact with the anti-displacement plates 7 on both sides. Through the arrangement of the anti-displacement plates 7, a limiting effect is exerted on the acoustic absorption layer 3, so that the acoustic absorption layer 3 can be stably clamped in the inner cavity of the pre-embedded pipe sleeve 1, thereby avoiding the acoustic absorption layer 3 being displaced during the insertion process of the wall-piercing pipe 2. The acoustic absorption layer 3 is polyester fiber acoustic absorption cotton. A heat-insulating layer 4 is arranged on the surface of the wall-piercing pipe 2. The heat-insulating layer 4 is a rubber and plastic heat-insulating sleeve. Both the acoustic absorption layer 3 and the heat-insulating layer 4 are respectively pasted on the inner wall of the pre-embedded pipe sleeve 1 and the surface of the wall-piercing pipe 2 through white latex. Sealing covers 5 are arranged on both sides of the pre-embedded pipe sleeve 1, and an installation component 6 is arranged between the sealing covers 5 and the pre-embedded pipe sleeve 1.

[0032] Embodiment 2:

[0033] Combined with Figures 1-4, the installation component 6 includes a circular card slot 61 opened in the inner cavity of the cover 5. The circular card slot 61 is sleeved on the surface of the embedded pipe sleeve 1. Three threaded seats 65 integrally formed by injection molding are annularly distributed in the inner cavity of the circular card slot 61. Three arc-shaped positioning grooves 62 are annularly opened on both sides of the surface of the embedded pipe sleeve 1. The threaded seats 65 are engaged in the inner cavities of the arc-shaped positioning grooves 62. Three circular grooves 63 are annularly opened on the side of the cover 5 away from the embedded pipe sleeve 1. A bolt 64 is threadedly connected in the inner cavity of the circular groove 63. One end of the bolt 64 penetrates through the cover 5 and is threadedly connected with the threaded seat 65. Through the arrangement of the installation component 6, the threaded seats 65 and the arc-shaped positioning grooves 62 play a role in positioning and clamping the cover 5. At the same time, the circular grooves 63 and the bolts 64 are used in cooperation to play a role in connecting and fixing between the embedded pipe sleeve 1 and the cover 5, so that the cover 5 can be stably installed on the surface of the embedded pipe sleeve 1 to seal and shield the embedded pipe sleeve 1 and the materials on its surface.

[0034] Working principle: When the utility model is used, the user first embeds the embedded pipe sleeve 1 in the wall through the cement mortar 8 during the civil engineering stage. Then, the sound-absorbing layer 3 is adhered to the inner wall of the embedded pipe sleeve 1 through white latex. Then, the user adheres the heat-insulating layer 4 to the surface of the wall-piercing pipe 2 through white latex and penetrates the wall-piercing pipe 2 into the inner cavity of the embedded pipe sleeve 1, so that the surface of the wall-piercing pipe 2 is in close contact with the sound-absorbing layer 3. Then, two covers 5 are sleeved on the surface of the wall-piercing pipe 2, so that the two covers 5 are respectively located on both sides of the wall. Then, the user pushes the cover 5 so that the circular card slot 61 is sleeved on the end of the embedded pipe sleeve 1, and the threaded seat 65 is engaged in the inner cavity of the arc-shaped positioning groove 62 to position the cover 5. Finally, the user inserts the bolt 64 into the inner cavity of the circular groove 63 and rotates the bolt 64 so that the bolt 64 is threadedly connected in the inner cavity of the threaded seat 65 to install and fix the cover 5, so that the cover 5 can be closely attached to the surface of the wall to shield the embedded pipe sleeve 1 and the surrounding materials. During the use process, the sound-absorbing layer 3 can adsorb the noise generated in the inner cavity of the wall-piercing pipe 2 to reduce the sound. At the same time, through the arrangement of the heat-insulating layer 4, heat preservation protection is carried out on the wall-piercing pipe 2 to avoid frostbite caused by the wall-piercing pipe 2 in winter.

[0035] To sum up: For this heat-insulated air duct or water pipe wall-piercing node, through the combined use of the sound-absorbing layer 3 and the heat-insulating layer 4, sound absorption and heat preservation protection are carried out on the surface of the wall-piercing pipe 2. At the same time, through the arrangement of the installation component 6, the cover 5 is installed and fixed, so that the cover 5 can stably clamp and fix the embedded pipe sleeve 1 and shield the sound-absorbing layer 3 and the heat-insulating layer 4, and the purpose of reliable installation, stability and effective protection of the pipe can be achieved.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
