Abstract
The utility model provides a heat preservation pipe which is composed of an outer pipe, an inner pipe, heat insulation and preservation padding and a heat insulation and preservation pipe. The inner pipe is sleeved with the outer pipe, and an annular gap is formed between the inner pipe and the outer pipe. The heat insulation and preservation pipe is arranged in the annular gap, and the space formed by the outer wall of the heat insulation and preservation pipe, the outer wall of the inner pipe and the inner wall of the outer pipe is provided with the heat insulation and preservation padding. The inner pipe of the heat preservation pipe is used for carrying fluid to pass through, and the outer pipe has a protecting and supporting function; air in the heat preservation and insulation pipe arranged between the outer pipe and the inner pipe can have the function of relieving heat conduction; meanwhile, the heat insulation and preservation function of the heat insulation and preservation pipe and the heat insulation and preservation padding is achieved in a cooperation mode, the three functions are matched, heat conduction towards the outer wall of the pipe is relieved, and the good heat preservation effect is achieved. In addition, the structure of the heat insulation and preservation pipe can have a function of reducing the weight of the pipe, transportation is convenient, and therefore the heat preservation pipe has the advantages of being capable of preserving heat and low in weight.
Description
Technical field
The utility model relates to tubing technical field, especially a kind of heat-insulating pipe.
Background technique
The sidewall of current heat-insulating pipe is thermal-protective coating to be set in sidewall to reach the effect of insulation mostly, the thermal-protective coating arranging is mostly solid layer, heat insulation effect is general, and the density that is greater than pipe material in the density of thermal-protective material, can greatly improve the weight of tubing, make troubles to transportation.
Model utility content
The purpose of this utility model is to provide a kind of heat-insulating pipe, and the heat of tubing inside is difficult for to outer pipe wall conduction, high insulating effect.
In order to achieve the above object, the utility model provides following technological scheme: a kind of heat-insulating pipe, formed by outer tube, inner tube, heat-insulation and heat-preservation filler and heat-insulation and heat-preservation pipe, interior pipe box is to outer tube, between inner and outer tubes, form annular space, heat-insulation and heat-preservation pipe is set in described annular space, in the space forming, heat-insulation and heat-preservation filler is set between heat-insulation and heat-preservation pipe outer wall, outer wall of inner tube and outer tube wall.
Further, the quantity of described heat-insulation and heat-preservation pipe is at least 4, and the quantity of heat insulating tube is more, and the quality of heat-insulating pipe is lighter; Certainly the volume that heat-insulation and heat-preservation pipe occupies in annular space can not exceed 80%, that is, need heat-insulation and heat-preservation pipe and heat-insulation and heat-preservation filler to be used in conjunction with, to reach good insulation and the effect of lightweight.
Further, between the outer wall and outer wall of inner tube of described heat-insulation and heat-preservation pipe, and space is all set between the outer wall of heat-insulation and heat-preservation pipe and outer tube wall.
Particularly, the volume of the described heat-insulation and heat-preservation pipe of setting is the 50%-80% of annular space volume.
Optimally, the volume of the described heat-insulation and heat-preservation pipe of setting is 60% of annular space volume.
Particularly, the material of described outer tube adopts the conventional material of current commercially available tubing, and the material of described inner tube adopts the conventional material of current commercially available tubing.
Particularly, described heat-insulation and heat-preservation filler can have for PVC＝polyvinyl chloride etc. the material of heat preservation and insulation.
Particularly, the material of described heat-insulation and heat-preservation pipe can have for PVC＝polyvinyl chloride or other material of heat preservation and insulation.
The inner tube of heat-insulating pipe of the present utility model is passed through for the fluid that delivers, outer tube plays the effect that protection is supported, air in the heat-insulation and heat-preservation pipe arranging between outer tube and inner tube can play the effect that reduces heat conduction, coordinate the thermal insulation function of heat-insulation and heat-preservation pipe and heat-insulation and heat-preservation filler simultaneously, three cooperatively interacts, reduce the conduction of heat to outer pipe wall, play good heat insulation effect, and, the structure of heat-insulation and heat-preservation pipe can play the effect that reduces tubing weight, convenient transportation, therefore, heat-insulating pipe of the present utility model has advantages of insulation and light weight simultaneously.
