Abstract
This application discloses a kind of heat-insulating pipelines, including protective layer, duct wall and the supporter of centre, which is characterized in that form insulated cavity, supporter uniformly interruption setting in pipe lengths by the fixed support of supporter between protective layer and inner wall of the pipe.
Description
Technical field
The present invention relates to a kind of pipeline more particularly to a kind of heat-insulating pipelines.
Background technique
In life, market needs the loose hot water of medium and long distance, and the energy mediums such as hot vapour are being conveyed and should kept away as far as possible in the process
Exempt from the loss of energy, improves transfer efficiency.Industrial at present and civil pipeline conveys high-temperature medium, frequently with the additional stone of metal tube
The tubing of cotton layer and rubber layer structure, has certain heat insulation, but could be improved.
Summary of the invention
In view of drawbacks described above in the prior art or deficiency, it is intended to provide a kind of heat-insulating pipeline for reducing energy loss.
The present invention provides a kind of heat-insulating pipeline, including protective layer, duct wall and the supporter of centre, which is characterized in that protects
Insulated cavity is formed by the fixed support of supporter between sheath and inner wall of the pipe, supporter is uniformly interrupted in pipe lengths
Setting.
As a further solution of the present invention: it is characterized in that, uniform along pipe lengths in the insulated cavity
Equipped with sealing ring.
As a further solution of the present invention: it is characterized in that, according to one kind described in claims 1 and claim 2
Heat-insulating pipeline, which is characterized in that carbon dioxide gas is full of in insulated cavity.
In conclusion the beneficial effects of the present invention are: a kind of heat-insulating pipeline of the invention, forms heat-insulated sky using supporter
Chamber, supporter are uniformly interruption setting, reduce the cross-sectional area of supporter, and less heat-conducting area reduces energy loss.
Two are full of in seal cavity so that insulated cavity forms seal cavity one by one using the sealing ring of interruption setting simultaneously
Carbon oxide gas, and carbon dioxide gas is the gas that thermal conductivity is minimum in common gas, thermal conductivity is far below normal air, and
Carbon dioxide chemistry property is stablized, and is not easy to react with duct wall and protective layer, plays the role of reducing heat loss.
