Abstract
The utility model discloses a vacuum insulation pipe, including inlayer pipe and outer pipe, be equipped with the vacuum layer between inlayer pipe and the outer pipe, scribble metallic reflective coating on the intraformational pipe wall in vacuum. Vacuum insulation pipe can set up the structure into multiple layer vacuum. Low, effectual, the long service life of keeping warm of vacuum insulation pipe thickness, construction convenience and low cost.
Description
Technical field
The utility model relates to a kind of pipeline heat insulation device, is specifically related to a kind of vacuum heat-preserving tube.
Background technique
At present, the insulation of material transferring pipeline mainly adopts the mode of parcel heat-preservation cotton, and the cotton thickness of conventional vacuum is high, heat insulation effect is poor, and large losses heat energy in transmitting procedure, causes the waste of resource.Existing vacuum insulation need arrange thermal insulation layer at internal layer, and cost is higher, and implementation process is comparatively complicated, reflecting layer adopt metal foil, reflecting effect is poor, and metal foil in use likely tilt affect vacuum heat-preserving effect.
Model utility content
The utility model is for the proposition of above problem, and a kind of vacuum heat-preserving tube of research and design, solve the shortcoming that in prior art, heat insulation effect is poor, cost is high and use is complicated.The technological means that the utility model adopts is as follows:
A kind of vacuum heat-preserving tube, comprises inner tube and external pipe, is provided with vacuum layer between described inner tube and external pipe, the tube wall in described vacuum layer scribbles metal reflective coating.
Further, the two-layer above vacuum layer that interlayer is divided into is provided with between described inner tube and external pipe.
Further, described metal reflective coating is silver-colored electrodeposited coating, electroplated aluminum layer or magnesium electrodeposited coating, and electrodeposited coating is arranged on the outer wall of inner tube.
Further, the thickness of described vacuum layer is 1 ~ 10mm.
Further, the thickness of described vacuum layer is 2 ~ 8mm.
Further, the thickness of described vacuum layer is 5 ~ 7mm.
Further, the thickness of described vacuum layer is 6mm.
Further, the length of vacuum heat-preserving tube is 0.2 ~ 10m.
Further, vacuum heat-preserving tube is made up of metal, plastics or glass.
Further, vacuum heat-preserving tube is made up of steel, plexiglass, PC, PE or glass, preferred glass.
Compared with the prior art, vacuum heat-preserving tube thickness described in the utility model low, high insulating effect, long service life, easy construction and with low cost.

Embodiment
As Figure 1-5, a kind of vacuum heat-preserving tube, comprise inner tube 1 and external pipe 2, be vacuum layer 3 between described inner tube 1 and external pipe 2, at utmost reduce convection current and conduct the heat loss brought, tube wall in described vacuum layer 3 scribbles metal reflective coating, reduces the heat loss that thermal radiation brings.During use, vacuum heat-preserving tube is sheathed on outside delivery line, between vacuum heat-preserving tube and delivery line, buffer gasket 4 can be set, reduce the damage to thermal insulation pipe, when delivery line is longer, more piece vacuum heat-preserving tube can be connected and use, and the thermal insulating material such as asbestos or felt can be set in joint, reduce the heat loss of joint.
The two-layer above vacuum layer 3 that interlayer is divided into is provided with between described inner tube 1 and external pipe 2, in actual mechanical process, due to can not perfect vaccum be reached, when requiring higher to thermal insulation property, the form of multi-layer vacuum can be adopted, improve thermal insulation property further.
Described metal reflective coating is silver-colored electrodeposited coating, electroplated aluminum layer or magnesium electrodeposited coating, and electrodeposited coating is arranged on the outer wall of inner tube 1, and plated reflective layer is evenly distributed, reflectivity is comparatively strong, can reduce the thermal loss that thermal radiation brings to greatest extent.
The thickness of described vacuum layer 3 is 1 ~ 10mm.
The thickness of described vacuum layer 3 is 2 ~ 8mm.
The thickness of described vacuum layer 3 is 5 ~ 7mm.
The thickness of described vacuum layer 3 is 6mm.
The length of vacuum heat-preserving tube is 0.2 ~ 10m, and concrete length is determined according to concrete pipeline, is generally 1 ~ 4m, can arranges the different sizes such as 1m, 2m, 4m.
Vacuum heat-preserving tube is made up of metal, plastics or glass, specifically carries out the selection of thermal insulation pipe material according to the medium temperature in delivery line.
Vacuum heat-preserving tube is made up of steel, plexiglass, PC, PE or glass, preferred glass.Existing glass types is various in the market, and technical maturity, especially toughened glass, intensity is very high, can meet construction requirement.
Fig. 1 and Fig. 2 is the structural representation of the utility model one embodiment, and the present embodiment is individual layer vacuum layer structure, comprises inner tube 1 and external pipe 2, is vacuum layer 3 between described inner tube 1 and external pipe 2.
Fig. 3 and Fig. 4 is the structural representation of another embodiment of the utility model, and the present embodiment is double-layer vacuum Rotating fields, comprises inner tube 1, external pipe 2 and middle tube 5, and there is two-layer vacuum layer 3 centre.
As shown in Figure 5, under enforcement state, vacuum heat-preserving tube is sheathed on outside delivery line 6, and is provided with buffer gasket 4 between vacuum heat-preserving tube and delivery line 6, and buffer gasket 4 can be the various packing ring with shock-absorbing capacity such as rubber washer or cotton pad circle.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and inventive concept thereof and replace or change, all should be encompassed within protection domain of the present utility model.
