An energy-saving building heating pipe

Abstract

The invention discloses a heating pipe for energy-saving buildings, which includes an inner pipe, a protective pipe, a cladding structure, a guide block, a gear ring, a screw, a rotating shaft, a thermal insulation layer, a fixing structure and a fixing screw. The beneficial effects of the invention are: By setting the protective tube outside the inner pipeline, when the thermal insulation layer is placed between the inner pipeline and the protective tube, the protective tube can prevent the thermal insulation layer from being corroded by the external environment, thereby prolonging the service life of the thermal insulation layer. And at the same time improve the heat preservation effect of the inner pipe, and the two ends of the inner pipe are provided with a gear ring that is rotatably connected with the inner pipe, and a guide block is fixedly connected to the gear ring, and the two ends of the insulation layer can be fixed through the guide blocks at both ends , and through the rotation of the screw, the gear ring is driven to rotate around the inner pipe, and finally the insulation layer can be evenly and tightly coated on the surface of the inner pipe, so as to achieve the effect of heat preservation on the inner pipe, and at the same time facilitate the rapid replacement of the insulation layer .

Description

technical field [0001] The invention relates to a heat supply pipeline, in particular to a heat supply pipeline for an energy-saving building, and belongs to the technical field of building heat supply. Background technique [0002] The heat pipe network, also known as the heat pipe, starts from the boiler room, direct-fired machine room, heating center, etc., and leads from the heat source to the heat supply pipe of the building's heat entrance. Multiple heating pipes form a pipe network. The design pressure of the heating hot water medium is less than or equal to 2.5MPa, and the design temperature is less than or equal to 200°C; the design pressure of the heating steam medium is less than or equal to 1.6MPa, and the design temperature is less than or equal to 350°C. In order to keep the heating pipes warm, insulation materials are usually wrapped on the outside of the heating pipes to prevent heat loss from the heating pipes too quickly. [0003] When the heat-supply pip...

AI Technical Summary

Problems solved by technology

[0003] When the heating pipe is insulated by covering the surface of the heating pipe with an insulation layer, the insulation layer coated on the outside of the pipe is easy to rot due to moisture, resulting in a decline in the insulation effect, and it is inconvenient to replace
