Description
Technical field
The utility model relates to steam insulation pipe, particularly relates to a kind of new and effective direct buried steam pipeline.
Background technique
Along with the development of China's cities and towns centralized heating project, the particularly development of thermoelectric cold triple supply industry, the construction of high temperature steam pipeline is by increasing, beautifying requirement usually restriction conduit being built on stilts of environmental protection and cities and towns is laid, especially the many pipe networks in underground, old city town interleaved arrangement in length and breadth, bring a lot of difficulty to in-duct installation, development directly-buried layout is more suitable approach.Along with the development of domestic and international Heat Supply Engineering technology, defeated stripping temperature and increasing pressure high, caliber is increasing; Environmental requirement is more and more stricter; Add the development of thermal insulating material and heat preservation technology in recent years, the aggravation of market competition, raising need be improved to prior art.Object reduces costs, and increases the service life, and improves energy-saving benefit.
The directly buried installation of high temperature steam pipeline is comparatively maked somebody a mere figurehead to lay and is compared, and have more characteristic and technological difficulties, the hot water of less than 130 DEG C widely applied at present and low pressure steam pipeline generally adopt the cruel foam thermal insulation of poly-ammonia to add high density polyethylene (HDPE) jacket structure; And the high temperature steam pipeline majority of 130 ~ 320 DEG C adopts inorganic combination with organic phase or pure inorganic compound insulation structure.Wherein the inorganic insulating structure practical application effect be combined with organic phase is pretty good, but there is the problem that too much, the axial gas permeability of seam is poor, operating expenses is high, cost is higher.
Model utility content
Technical problem to be solved in the utility model is, provides that a kind of seam is few, speed of application is fast, cost is low and the new and effective direct buried steam pipeline of good permeability.
The utility model solves the technological scheme that its technical problem adopts: a kind of new and effective direct buried steam pipeline, comprises steam tube, calcium silicate supporting component, glass fibre cotton shell, aluminosilicate fiber cotton composite pipe shell, aluminium foil reflecting layer, polyurethane insulation coating, outer protective layer; Drag reduction layer is provided with between described calcium silicate supporting component and steam tube; Described glass fibre cotton shell is wrapped on steam tube, and glass fibre cotton shell is surrounded by one deck aluminosilicate fiber cotton composite pipe shell outward again; Described glass fibre cotton shell and glass fibre cotton shell stacked after and calcium silicate supporting component be spaced on steam tube; Described aluminosilicate fiber cotton composite pipe shell and calcium silicate supporting component outer surface are also provided with polyurethane insulation coating, and polyurethane insulation coating outer surface is wrapped in outer protective layer.
Described glass fibre cotton shell and aluminosilicate fiber cotton composite pipe shell are main thermal insulation layer.
Glass fibre cotton shell and glass fibre cotton shell stacked after and calcium silicate supporting component be spaced on steam tube, steam tube uses compartment structure, glass fibre cotton shell calcium silicate supporting component hard insulating material supports, and intensity is high, and thermal insulation layer can be prevented to be out of shape.
Improve further as the utility model, described aluminosilicate fiber cotton composite pipe shell outer surface adds one deck aluminium foil reflecting layer.
Improve further as the utility model, between described glass fibre cotton shell and aluminosilicate fiber cotton composite pipe shell, add one deck aluminium foil reflecting layer, form Low emissivity heat transfer structure, improve insulating efficiency.
The utility model, the structure that a kind of new and effective direct buried steam pipeline adopts highdensity glass fibre cotton shell alternate with hard calcium silicate shell with aluminosilicate fiber cotton composite pipe shell can improve the speed of application installing thermal insulation pipe greatly, ensure that the radiation loss of seam contact is consistent with integral heat insulation pipe, can prevent the weight because of working pipe from causing thermal insulation layer to be out of shape, insulation insulation effect is good, and can effectively reduce overall cost.One deck aluminium foil reflecting layer is added at aluminosilicate fiber cotton composite pipe shell outer surface, under equivalence insulation prerequisite, can thinning insulation layer thickness, save the consumption of external thermal insulation temperature-resistant material and outer protective layer and other external protective material, can reduce costs.
The structure composition of the new and effective direct buried steam pipeline advantage of hard and semi-rigid bi-material, both hard material intensity had been played high, can support works tubular loading and thermal insulation layer guide function, play again that semi-rigid material seam is few, speed of application is fast, cost is low and the advantage of good permeability, the double effects improving performance and reduce cost can have been reached.
