Insulating pipe

Abstract

The invention relates to a thermal insulation pipe, which includes a straight-through inner tube of the thermal insulation tube, and a heat insulation cavity that wraps the outer wall of the inner tube of the heat insulation tube. The heat insulation cavity is located in a closed shell, and the inside of the heat insulation cavity is a vacuum Or filled with insulating medium. Further, it also includes the outer pipe of the heat preservation pipe, the inner diameter of the outer pipe of the heat preservation pipe is larger than the outer diameter of the inner pipe of the heat preservation pipe, and the two ends of the outer pipe of the heat preservation pipe are closing places, and the closing places are sealed and connected to the outer wall of the inner pipe of the heat preservation pipe, so that The closed shell is composed of the outer tube of the thermal insulation tube, the inner tube of the thermal insulation tube and the closing part. The insulation pipe of the present invention has a vacuum layer between the inner pipe and the outer pipe or is filled with a heat insulating medium, which can reduce the heat loss of the internal material and realize heat preservation. Because the pipe does not need to be wrapped with an insulation layer, there will be no outside of the traditional heat preservation pipe. The insulation material is easily damaged, especially suitable for places with relatively chaotic order such as construction sites.

Description

technical field [0001] The invention relates to a pipe with heat preservation function. Background technique [0002] Pipes are common parts in production and life, which can be used to transport liquid or gas. When it is necessary to insulate the material inside the pipe, such as the hot water delivery pipe of a solar water heater, an insulation pipe is required. Existing insulation pipes are realized by wrapping insulation materials on the periphery of ordinary pipes, such as wrapping insulation sponge and aluminum foil on the outside of metal pipes. Sponge and aluminum foil can slow down the outward diffusion of heat in the container and realize the insulation function. [0003] However, both aluminum foil and sponge are materials that are relatively easy to break, which causes this insulation pipe to lose its original insulation function due to the damage of the external insulation material when it is used in places with many people.
