Abstract
The utility model discloses a vacuum heat-insulation high-temperature pipeline, which comprises an inner sleeve and an outer sleeve. The vacuum insulation high-temperature pipeline is characterized in that a vacuum sandwich structure is formed by the inner sleeve and the outer sleeve; an insulating layer and a reflective layer are arranged on the outer wall of the inner sleeve inside a sandwich layer; a heat insulation supporting ring is arranged between the inner sleeve and the outer sleeve; an inner sleeve flange and an outer sleeve flange are respectively arranged at the two ends of the heat insulation supporting ring and tightened through bolts; a sealing gasket is arranged between the two flanges for sealing; an airtight vacuum unit pipe stack is formed between the inner sleeve and the outer sleeve; a thermal expansion compensator is arranged at one end of the inner sleeve; and a vacuum gauge is arranged on the outer sleeve so as to monitor the vacuum condition inside the unit pipe stack. By adopting the vacuum heat insulation mode, the utility model has the advantages of energy conservation, water resistance, safety and reliability.
Description
Technical field
The utility model relates to the insulation of high-temperature pipe, particularly a kind of vacuum insulation high-temperature pipe.
Background technique
The thermal insulation of high-temperature pipe generally is divided into piles up insulation thermal insulation and vacuum insulation, and what heat distribution pipeline was commonly used at present is to pile up the insulation insulated piping.Piling up the insulation insulated piping is to coat the low thermal insulating material of high thermal conductivity outside pipeline, as glass fibre, foam asbestus, rock wool, silicate aluminum board and insulating brick etc.This kind pipeline is at the beginning of putting into operation or when being interrupted heat supply, airborne moisture and gas molecule can slowly suck its thermal insulation layer inside, thereby reduction thermal insulation property, make heat insulation effect ineffective gradually, As time goes on, the water-soaked situation of whole thermal insulation layer will occur, thereby cause insulation effect thoroughly to lose efficacy.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of vacuum insulation high-temperature pipe, adopts the vacuum insulation mode, and energy-conservation, waterproof is safe and reliable.
The utility model vacuum insulation high-temperature pipe comprises inner sleeve, outer sleeve, it is characterized in that inner sleeve and outer sleeve constitute the vacuum sandwich structure, and the outer wall in inner sleeve in interlayer is added with thermal insulation layer.
Interlayer system between the inside and outside sleeve pipe adopts high vacuum, has effectively stopped the heat transfer by convection that air causes.Can be added with reflecting layer (as the aluminium film etc.) outside the thermal insulation layer in interlayer again, adopt reflecting layer and thermal insulation layer in the interlayer, greatly reduce radiative heat transfer.
Between inner sleeve and outer sleeve, can be provided with heat insulation support ring, two ends are respectively equipped with inner sleeve flange and outer sleeve flange, and by bolton together, between two flanges, have gasket seal to seal, between inside and outside sleeve pipe, form an enclosed vacuum unit pipe group.
End at inner sleeve is provided with thermal expansion compensator, is provided with vacuum gauge with the vacuum condition in the monitor unit pipe group on outer sleeve, can not consider the thermal compensation problem when design and construction, reduces a large amount of design and engineering time.
Can adopt electric welding to connect between each unit pipe group, form the pipeline of long transfer heat.
Advantage of the present utility model:
1, energy-conservation: reduce heat loss more than 70% than traditional insulation pipe, more energy-conservation more than 20% than steel bushing steel insulation pipe.
2, save time: unit pipe group inside is provided with thermal expansion compensator, can not consider the thermal compensation problem when design and construction, reduces a large amount of design and engineering time.
3, province's expense: the outer sleeve of vacuum insulation high-temperature pipe is actionless mutually to external world, and the thrust problem can not be considered on civil engineering fixed support basis, reduces support bracket fastened investment, and improves safety reliability.To compare the outer sleeve caliber little with steel bushing steel direct-buried pipeline, reduces investment, saves steel and thermal insulating material.
4, waterproof: outer sleeve adopts steel pipe, both can also can make somebody a mere figurehead by direct-burried, and flexibility is big, and water-proof performance is good.
