Pipeline heat-insulation device for heat supply

Abstract

The invention discloses a pipeline heat-insulation device for heat supply. A filling material is arranged below a top cover, and a right-side cover wall is fixed to the right side of the top cover; aleft-side cover arm is fixed to the left side of the top cover; a heat-insulation pipe is connected below a pipe cover, and fixed slopes are arranged at the left end and the right end of the heat-insulation pipe separately; a bottom cover is fixed below the fixed slopes, and a bottom groove is inlaid in the inner surface of the bottom cover; a pipe pad is installed at the bottom end of the heat-insulation pipe, and a fixing hole is formed below the pipe pad; a flame-retardant, heat-insulation and heat-isolation layer is arranged in the heat-insulation pipe, and a vacuum layer is arranged in the flame-retardant, heat-insulation and heat-isolation layer; and a heat-conducting layer is arranged in the vacuum layer. The heat-conducting layer, the vacuum layer and the flame-retardant, heat-insulation and heat-isolation layer are arranged; the heat-conducting layer is capable of absorbing a part of heat in a heat supply pipe and then transferring the heat to the flame-retardant, heat-insulation and heat-isolation layer; then the flame-retardant, heat-insulation and heat-isolation layer transfers the accumulated heat to the surrounding to avoid surface icing in the case of a low temperature; and moreover, the vacuum layer is capable of slowing down the transferring for the heat, so that the heat is reserved at the maximum efficiency.

Description

technical field [0001] The invention relates to the technical field of pipeline insulation devices, in particular to a pipeline insulation device for heating. Background technique [0002] The heat preservation effect of the existing heating pipes is poor. In order to avoid the internal heat loss of the heating pipes due to the low external temperature or the heat exchange with the air when the temperature is low, it is necessary to install an insulation device for the heating pipes. . The current heating pipe insulation device generally uses on-site manual splicing of the outer shell of the heating pipe, the insulation efficiency is not high, the service life is limited, and the deformation buffer absorption capacity of the heating pipe is not strong; when the direction of the heating pipe line changes, it cannot Repeated use; easy to freeze, poor heat preservation effect, serious heat loss, resulting in the problem that the liquid temperature drops during the transportati...
