The part between the pipeline and the outside shielding layer is successively provided with a hard insulating layer, a reflecting layer and soft insulating and reflecting layer from inner to outer, wherein, the hard insulating layer is composed of fastened heat preservation tiles made of hard high temperature resistant insulating material. The reflecting layer is composed of high temperature resistant fiber fabric which is compounded with metal foil. The soft insulating and reflecting layer is composed of a soft insulating layer and a reflecting layer which are made of soft high temperature resistant insulating material. The utility model has the advantages of high intensity and good anti-deformability of the pipeline because the utility model is provided with the soft insulating layer and the hard insulating layer simultaneously. The utility model is characterized in that the utility model can preserve the heat of the pipeline simultaneously by obstructing the heat transfer of the heat conduction, the heat convection and the heat radiation, because the reflecting layer which is provided with good obstructing effect on heat transfer is arranged in the utility model.
Description
Affiliated technical field
The utility model relates to a kind of improved insulating structure, particularly relates to a kind of improved high-temperature pipe insulating structure.
Background technique
At present, the insulating structure of existing high-temperature pipe is divided into two kinds on soft insulating structure and hard heat-insulated structure; Wherein soft insulating structure exists the low defective of intensity, when it is subjected to the bump of external force or pushes, is easy to distortion and subsides, thereby have a strong impact on its heat preservation effect; And the defective of many, the anti-pipe deforming poor performance in slit between being existed watt by hard heat-insulated watt of hard heat-insulated structure that constitutes when pipeline is subjected to thermal stretching, can produces bigger slit between hard heat-insulated watt watt end face and reduce its thermal insulation property greatly; And existing hard heat-insulated structure and the soft insulating structure that is used for high-temperature pipe insulation usefulness all can only come high-temperature pipe is incubated from stoping the angle that heat transfer by heat conduction and thermoconvection are conducted heat, and conducts heat powerless to thermal radiation.
Summary of the invention
The purpose of this utility model provides a kind of intensity height, and anti-pipe deforming performance is good, and the improved high-temperature pipe insulating structure that can conduct heat and effectively intercept heat transfer by heat conduction, thermoconvection heat transfer and thermal radiation simultaneously.
The purpose of this utility model is achieved in that a kind of improved high-temperature pipe insulating structure, comprise pipeline and outermost protective coating, wherein between pipeline and outermost protective coating, also be disposed with hard heat-insulated layer, reflecting layer and soft insulation reflection stratum conjunctum from the inside to the outside; The insulation tile that wherein hard heat-insulated layer is made by the usefulness hard refractory thermal insulating material of mutual fastening is formed; The reflecting layer is made up of the high-temperature-resistant fiber fabric that is compounded with metal foil; Soft insulation reflection stratum conjunctum is made of jointly soft thermal insulation layer made from soft high-temperature-resistant thermal-insulation material and reflecting layer.
Owing to include soft thermal insulation layer and hard heat-insulated layer in the utility model simultaneously, and the hard heat-insulated layer that the utility model will have good strength is arranged on internal layer, and the soft thermal insulation layer that will have good resistance pipe deforming performance and sealability is arranged on skin, so the utility model has the high and good characteristics of anti-pipe deforming of intensity simultaneously; In addition, owing to also be provided with the reflecting layer that has metal foil that the thermal radiation heat transfer is had the good barrier effect among the utility model, the utility model can be incubated pipeline from the angle that intercepts heat transfer by heat conduction, thermoconvection heat transfer and thermal radiation heat transfer simultaneously.
