Description

Technical Field

[0001] This utility model relates to the field of building water supply and drainage pipeline technology, specifically to a condensation prevention structure for building water supply and drainage pipelines. Background Technology

[0002] The core purpose of anti-condensation is to prevent water vapor in the air from condensing into liquid water on the surface of the pipe when the outer surface temperature is lower than the dew point temperature of the surrounding air. This avoids condensation water from polluting ceilings, walls, floors, equipment, etc., causing economic losses and hygiene problems. Currently, anti-condensation is mainly achieved by wrapping the outer surface of the pipe with an insulation layer. The existing treatment for the joints of the insulation material is usually to use tape or sealant. However, in actual use, insufficient overlap of the tape or poor adhesion will allow water vapor to penetrate the insulation layer, which will then affect the pipe or cause hygiene problems. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a condensation prevention structure for building water supply and drainage pipes. This solves the current problem of mainly preventing condensation by wrapping the outer surface of the pipe with an insulation layer. The existing treatment for the splicing of insulation materials is usually to use tape or sealant to connect them. However, in actual use, insufficient overlap of the tape or poor adhesion will allow water vapor to penetrate the insulation layer, thereby affecting the pipe or causing hygiene problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a condensation prevention structure for building water supply and drainage pipes, comprising a pipe body, the outer side of which is coated with a protective coating, and an insulation layer is sleeved on the outer side of which a plastic connector is installed on the outer side of the insulation layer, and a heat insulation layer is bonded below the plastic connector. Both the outer side of the plastic connector and the insulation layer are provided with a moisture-proof layer, and fixing bolts are inserted and installed on both sides of the plastic connector.

[0005] The beneficial effects of this utility model are as follows: the protrusions on the inner side of the insulation layer increase the friction between the insulation layer and the heat preservation layer, and the protrusions in the middle of the plastic connector can fill the joint between the heat preservation layers. In this way, the sealing of the joint between the heat preservation layers can be effectively guaranteed, thereby effectively preventing water vapor intrusion caused by poor overlap between the heat preservation layers, thus reducing the impact on the pipeline and hygiene problems.

[0006] To increase the friction between the insulation layer and the thermal insulation layer:

[0007] As a further improvement to the above technical solution: the inner circumferential side of the insulation layer is provided with protrusions.

[0008] The beneficial effects of this improvement are: the plastic connector pushes the insulation layer to squeeze the heat preservation layer, and the protrusions on the inner side of the insulation layer increase the friction between the insulation layer and the heat preservation layer.

[0009] To fill the joints between insulation layers:

[0010] As a further improvement to the above technical solution: the middle part of the plastic connector is integrally formed with a protrusion, and the cross-section of the protrusion is trapezoidal.

[0011] The beneficial effect of this improvement is that the protrusions, which are integrally molded, can fill the joint between insulation layers, thereby increasing the sealing performance at that location.

[0012] To facilitate the fixing of the insulation layer:

[0013] As a further improvement to the above technical solution: the plastic connector is semi-circular, and there are two plastic connectors.

[0014] The beneficial effects of this improvement are: the two semi-circular rings allow the plastic connectors to clamp the insulation layer from both the top and bottom, ensuring the efficiency and effectiveness of the plastic connectors in fixing the insulation layer.

[0015] To ensure easy installation of the plastic connectors:

[0016] As a further improvement to the above technical solution: a rubber pad is installed at the connection between the plastic connectors.

[0017] The beneficial effects of this improvement are: the rubber pad can seal the connection between plastic connectors, ensuring the sealing performance of the connection between plastic connectors.

[0018] To ensure aesthetic appeal:

[0019] As a further improvement to the above technical solution: the two ends of the plastic connector are inclined.

[0020] The beneficial effects of this improvement are: the inclined design at both ends makes the connection between the two ends of the plastic connector and the insulation layer smoother, making the plastic connector more aesthetically pleasing.

[0021] To ensure a tight seal:

[0022] As a further improvement to the above technical solution: the thermal insulation layer and the plastic connector are arranged with their axes coincident.

[0023] The beneficial effects of this improvement are: the overlapping axis setting makes it easier for the insulation layer to be used with plastic connectors to seal the joints of the insulation layer. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0031] like Figure 1-5As shown, a condensation-proof structure for building water supply and drainage pipes includes a pipe body 1. The outer side of the pipe body 1 is coated with a protective coating 11, and an insulation layer 2 is fitted over the outer side of the pipe body 1. A plastic connector 3 is installed on the outer side of the insulation layer 2, and a thermal insulation layer 31 is adhered below the plastic connector 3. Both the plastic connector 3 and the insulation layer 2 have moisture-proof layers 21 on their outer sides. Fixing bolts 4 are inserted and installed on both sides of the plastic connector 3. Protrusions on the inner side of the thermal insulation layer 31 increase the friction between the thermal insulation layer 31 and the insulation layer 2. Simultaneously, the plastic connector... The protrusion in the middle of the connector 3 can fill the connection between the insulation layers 2 and 2. The bottom of the plastic connector 3 fits against the pipe body 1. This method can effectively ensure the sealing of the connection between the insulation layers 2, thereby effectively preventing water vapor intrusion caused by poor overlap between the insulation layers 2 and 2, thus reducing the impact on the pipe and hygiene problems. The inner circumferential protrusion of the insulation layer 31 is provided with a protrusion. The plastic connector 3 pushes the insulation layer 31 to squeeze the insulation layer 2 and cooperates with the protrusion on the inner side of the insulation layer 31 to increase the gap between the insulation layer 31 and the insulation layer 2. Friction is addressed by an integrally formed protrusion in the middle of the plastic connector 3, which has a trapezoidal cross-section. This protrusion fills the connection between the insulation layers 2, increasing the seal at that location. The plastic connector 3 is semi-circular, and there are two of them. These two semi-circular rings allow the plastic connector 3 to clamp the insulation layer 2 from both ends, ensuring efficient and effective fixation of the insulation layer 2. The connection between the plastic connector 3 is secure. Equipped with rubber pads, the rubber pads can seal the connection between plastic connectors 3 and plastic connectors 3, ensuring the sealing performance of the connection between plastic connectors 3 and plastic connectors 3. The two ends of the plastic connectors 3 are inclined, which makes the connection between the two ends of the plastic connectors 3 and the insulation layer 2 more gradual and makes the plastic connectors 3 more aesthetically pleasing. The insulation layer 31 and the plastic connectors 3 are arranged with their axes coincident, which makes it easier for the insulation layer 31 to cooperate with the plastic connectors 3 to seal the connection between the insulation layer 2 and the insulation layer 2.

[0032] The working principle of this utility model is as follows: When using this device, the insulation layer 2 is sleeved on the outside of the pipe body 1, and the plastic connector 3 is sleeved on the outside at the connection between the insulation layers 2 and the insulation layer 2. Then, the plastic connector 3 is fixed with the fixing bolt 4. When fixing, the plastic connector 3 pushes the insulation layer 31 to squeeze the insulation layer 2 and cooperates with the protrusions on the inner side of the insulation layer 31 to increase the friction between the insulation layer 31 and the insulation layer 2. At the same time, the protrusion in the middle part of the plastic connector 3 can fill the connection between the insulation layers 2 and the insulation layer 2. In this way, the sealing of the connection of the insulation layer 2 can be effectively guaranteed, thereby effectively preventing water vapor intrusion caused by poor overlap at the connection between the insulation layers 2 and the insulation layer 2, thus reducing the impact on the pipeline and hygiene problems.
