Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building water supply and drainage, in particular to an anti-frost pipeline for building water supply and drainage. Background Art
[0002] Water supply and drainage pipes are one of the important and indispensable components of building construction. Their main function is to transport and distribute industrial water supply, domestic drinking water, and collect, transport and discharge industrial wastewater, domestic sewage and rainwater. When laying the pipes, due to limited conditions, some of them will be laid in the open. In this way, frost will occur inside the water supply and drainage pipes when the weather is cold, which will seriously affect the use of the water supply and drainage pipes. Although anti-frost pipes for building water supply and drainage are proposed in the prior art, they still have some shortcomings. For example, on winter nights, the temperature drops rapidly, and the anti-frost pipes cannot effectively cope with such situations, resulting in frost inside the pipes. Moreover, most of the anti-frost pipes in the prior art only use a passive insulation layer to carry out anti-frost treatment of the pipes. For this reason, we propose an anti-frost pipe for building water supply and drainage. Utility Model Content
[0003] The utility model aims to provide a building water supply and drainage anti-frost pipeline to solve the problems raised in the above background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A building water supply and drainage anti-frost pipeline comprises an external insulation layer, an outer protective pipe is sleeved on the inner wall of the external insulation layer, a heating sleeve is sleeved on the inner wall of the outer protective pipe, grooves are transversely arranged around the outer wall of the heating sleeve, heating plates are installed in the grooves, a sound-absorbing layer is sleeved on the inner wall of the heating sleeve, an insulation layer is sleeved on the inner wall of the sound-absorbing layer, a drainage pipe is sleeved on the inner wall of the insulation layer, and an anti-corrosion coating layer is evenly sprayed on the inner wall of the drainage pipe.
[0006] Furthermore: the outer wall of the external thermal insulation layer is sequentially sleeved with reinforcement ropes from left to right, and the outer wall of the external thermal insulation layer is provided with a waterproof protective layer.
[0007] Furthermore: a wiring hole is arranged at the top right side of the outer protective tube, and a matching through hole is arranged at a position corresponding to the wiring hole at the top right side of the outer thermal insulation layer.
[0008] Furthermore: a plurality of groups of arc-shaped grooves are arranged at positions corresponding to the grooves around the inner wall of the heating sleeve, and a plurality of groups of air holes are evenly arranged between the arc-shaped grooves.
[0009] Furthermore: the sound-absorbing layer is arranged as a sound-insulating sponge layer, and the inner wall and the outer wall of the sound-insulating sponge layer are both arranged with metal wire fabric mesh.
[0010] Furthermore: the heating plates are all configured as waterproof heating plates, and the openings of the grooves are all provided with matching cover plates.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The anti-frost pipe for water supply and drainage of this building has an insulation layer, a heating sleeve and an external insulation layer arranged on the outer wall of the drainage pipe from the inside to the outside. The insulation layer can perform insulation treatment from the inside of the overall pipe to prevent the external temperature from affecting the inside of the overall pipe. The heating sleeve has heating plates arranged through grooves around its outer wall. When the heating plates are turned on, they can generate heat, thereby heating the inside of the drainage pipe to avoid frosting. This can actively prevent frost. The external insulation layer can reduce the impact of the external temperature on the inside of the pipe, and also reduce the temperature loss inside the pipe. At the same time, it can effectively protect the drainage pipe in conjunction with the external protective pipe. BRIEF DESCRIPTION OF THE DRAWINGS
