Abstract
The utility model discloses a three-dimensional glass reinforced plastic and steel outer protective tube type precast vacuum direct-buried insulated pipe, comprising an inner work steel tube transferring the high-temperature medium and an outer protective tube. The outer protective tube is composed of the chopped fiber resin of alternating recombination outside the outer protective steel tube and the two-dimensional glass fiber gingham of zero twist. A vacuum insulated layer of multiple screen heat insulation is arranged between the inner work steel tube and the outer protective tube. The vacuum insulated layer of multiple screen heat insulation is orderly superimposed to form by the alternation of the shielding layer of aluminum foil and the superfine centrifugal glass wool. A work steel tube component is arranged the between the inner work steel tube and the outer protective tube. The work steel tube component is composed of a ring frame and a roll shaft arranged on the outside of the ring frame, as well as a slide roller movably arranged on the roll shaft. Having the strongest ability of acid resistance and alkaline resistance, the utility model can be directly used in region with the high ground water level, and the heat insulating effect can be enhanced further under the condition of pumping fine vacuum.
Description
Technical field
The utility model relates to directly buried type heat preservation hot solenoid, the specifically a kind of three-dimensional glass steel/prefabricated vacuum direct-buried insulated pipe of steel outer protective tube type.
Background technique
At present, be energy saving, beautify the environment that direct-buried mode is mostly adopted in laying of heat distribution pipeline.It is complicated to be used for the directly buried type heat distribution pipeline project organization that heat distribution pipe network uses in the prior art, a kind of is to adopt reinforced concrete outer fixing bearing, it is bigger that its deficiency is to take the underground space, increased the civil works expense of engineering, also extended the construction period; Another kind is (rolling) formula of sliding in using or outer (rolling) formula structure of sliding, support, fix by means of external protective steel tube or interior (core) working steel tube, its deficiency is that cold bridge is bigger, or the disconnection (channel) of formation thermal insulating material, the working steel tube heat-insulating property is also undesirable, energy-saving effect is poor, many unsatisfactory parts are in use still arranged, this employing steel bushing steel structure steam direct-buried Manifold technology, particularly steel pipe protects aseptic technic solution comprehensively as yet outward, pipeline, the pipe fitting corrosion water inlet that mostly occurs has reduced adiabatic heat insulating effect, makes the pipe applications life-span short.
The model utility content
The purpose of this utility model is to provide a kind of and is easy to construct, the prefabricated vacuum direct-buried insulated pipe of three-dimensional glass steel/steel outer protective tube type of mechanization or semi-automatic continuous anticorrosion production.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of three-dimensional glass steel/prefabricated vacuum direct-buried insulated pipe of steel outer protective tube type comprises interior working steel tube and the outer pillar of carrying high temperature media, and outer pillar replaces compound chopped strand-resin by the external protective steel tube outside and two-dimentional non-twist glass woven roving constitutes; Interior working steel tube and outside be provided with the multi shields insulation vacuum heat-insulating layer between the pillar, the multi shields insulation vacuum heat-insulating layer is successively by foil shielding layer and ultra-fine centrifugally glass-wool stacked the forming that alternate; Interior working steel tube and outside be arranged with the working steel tube assembly between the pillar; The working steel tube assembly is made up of ring support and the roll shaft and the slide roller wheel of movable set on roll shaft that are installed on the ring support outside.
Between interior working steel tube and working steel tube assembly, be provided with the high-strength heat-insulating material layer; In the working steel tube assembly outside three groups of slip running rollers are installed at least; The multi shields insulation vacuum heat-insulating layer is to operate under the pumping high vacuum condition, its whole vacuum layer that forms.
The beneficial effects of the utility model are:
1. sealing corrosion, strong shock resistance.Because the three-dimensional glass steel that the utility model adopts/steel is as outer pillar, promptly through the external protective steel tube of processing of rust removing outside continuous injection chopped strand-resin with twine alternately the be composited outer pillar of one of non-twist glass woven roving continuously, external protective steel tube has the water-tight function again except that shock resistance, protection insulating structure integrity, rigidity support; And three-dimensional glass steel (the three-dimensional glass steel is meant the chopped strand-resin layer of continuous injection and the non-twist glass grid layer of cloth that twines continuously) is the anticorrosion waterproof protecting layer of steel pipe; self is compound with steel pipe again; improve steel strength, strengthened the whole impact resistance of outer pillar.
2. high insulating effect reduces heat loss rate, obvious energy conservation.Insulating structure of the present utility model is a multi shields insulation radiation vacuum heat-insulating layer, adopts the foil shielding layer and the ultra-fine centrifugally glass-wool of high reflectance alternately to lay at interval, reduces radiative heat transfer, improves insulation efficiency, and during particularly by the hot operation medium, effect is better; In the pumping high vacuum operation, further reduce the heat transfer by convection loss, multi shields insulation radiation insulating structure usefulness is improved, thermal loss is reduced to more low-level.
3. long service life.Because working steel tube assembly of the present utility model is enclosed within on the interior working pipe by rolling running roller and ring support; and between ring support and interior working pipe, add a thermal-protective coating; further stop hot-fluid to be passed to ring support, rolling running roller and outer pillar by interior working pipe heat conduction; the protection external anti-corrosion layer is avoided heat erosion, has prolonged working life.
