Abstract
The invention discloses a sandwich high-pressure pipe which comprises an outer metal pipe, a hollow pipe and an inner metal pipe. The inner metal pipe is arranged on the innermost layer, the hollow pipe is sleeved on the inner metal pipe, the outer metal pipe is sleeved on the outside of the hollow pipe, the inner metal pipe is an aluminum alloy pipe, the outer metal pipe is a stainless steel pipe, a portion between the outer wall and the inner wall of the hollow pipe is hollow, and a plurality of support frames are arranged between the outer wall and the inner wall of the hollow pipe. The sandwich high-pressure pipe in the design has the advantages that the temperature of liquid in the pipe can be effectively kept, and the sandwich high-pressure pipe is safe and reliable.
Description
Technical field
The present invention relates to tubing manufacturing technology field, relate in particular to a kind of interlayer high-voltage tube.
Background technique
Nowadays high-voltage tube has been widely used in all trades and professions, yet some industry has higher requirement to the temperature of managing interior fluid transfer, too large variation can not be arranged, yet current pipeline is freeze proof and the high temperature resistance effect is scarcely desirable, is difficult to reach requirement.
Summary of the invention
The invention provides a kind of interlayer high-voltage tube, hollow tubular is set as interlayer, carrys out effective thermal insulation in high-voltage tube.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of interlayer high-voltage tube is characterized in that: comprise outer metal tube, hollow tubular and interior metal tube, described interior metal tube is located at innermost layer, and on it, cover has hollow tubular, and outside hollow tubular, cover has outer metal tube.
Preferably, described interior metal tube is Al-alloy pipe, and described outer metal tube is Stainless Steel Tube.
Preferably, between described hollow tubular outer wall and inwall, be hollow, between outer wall and inwall, be provided with some supporting frames.
Preferably, support frame as described above is 4.
Preferably, the internal diameter of described interior metal tube is 20mm, and outer metal tube external diameter is 26mm.
Preferably, the pipe thickness of described outer metal tube and interior metal tube is 2mm.
The beneficial effect that the present invention reaches is: with traditional high-voltage tube, compare, the present invention utilizes heat-insulated character that air is good can effectively keep the temperature of institute's fluid transfer in high-voltage tube.
The accompanying drawing explanation
Fig. 1 is the structural representation in a kind of interlayer high-voltage tube of the present invention cross section.
Embodiment
In order to further describe technical characterstic of the present invention and effect, below in conjunction with the drawings and specific embodiments, the present invention is described further.
With reference to Fig. 1, a kind of interlayer high-voltage tube, comprise outer metal tube 1, hollow tubular 3 and interior metal tube 2, described interior metal tube 2 is located at innermost layer, and its internal diameter is 20mm, in order to improve the thermal insulation effect of high-voltage tube, cover has hollow tubular 3 on interior metal tube 2, and in order further to reinforce, cover has outer metal tube 1 outside hollow tubular 3, its external diameter is 26mm, and the pipe thickness of interior metal tube and outer metal tube is 2mm.Because air has good thermal insulation effect, so be made as hollow between described hollow tubular 3 outer walls and inwall, between outer wall and inwall, supported by 4 supporting frames 4, durable in use in order to make tubing, outer metal tube 1 adopts Stainless Steel Tube, and interior metal tube 2 adopts Al-alloy pipe.
Above-described embodiment does not limit the present invention in any form, all take to be equal to replace or technological scheme that the form of equivalent transformation obtains, within all dropping on protection scope of the present invention.
