Heat supply pipeline for energy-saving building

Abstract

The invention discloses a heat supply pipeline for an energy-saving building. The heat supply pipeline comprises an inner pipeline, a protective pipe, a coating structure, guide blocks, gear rings, ascrew rod, a rotating shaft, a heat insulation layer, a fixing structure and a fixing screw rod. The heat supply pipeline has the beneficial effects that the protective pipe is arranged on the outer side of the inner pipeline, when the heat insulation layer with a heat insulation effect is arranged between the inner pipeline and the protective pipe, the protective pipe can prevent the heat insulation layer from being corroded by the external environment, so that the service life of the heat insulation layer is prolonged, and the heat insulation effect on the inner pipeline is improved at the same time; and the gear rings rotationally connected with the inner pipeline are arranged at the two ends of the inner pipeline, the guide blocks are fixedly connected to the gear rings, the two ends of the heat insulation layer can be fixed through the guide blocks at the two ends, the gear rings are driven to rotate around the inner pipeline through rotation of the screw rod, finally, the heat insulation layer can evenly and tightly wrap the surface of the inner pipeline, the heat preservation effect on the inner pipeline is achieved, and meanwhile the heat insulation layer can be conveniently and rapidly replaced.

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
