Abstract
The utility model provides an evacuating type thermal insulation casing of a steam pipeline, which belongs to improved technology of a steam pipeline thermal insulation tube and structurally comprises an inner thermal insulation layer tube. A thermal insulation casing is fixedly covered on the outer lateral face of the inner thermal insulation layer tube. The thermal insulation casing structurally comprises an inner tube and an outer tube, a support board is arranged between the inner tube and the outer tube with the same space, a cavity among the inner tube, and the outer tube and the support board is a sealed cavity. Both the inner tube and the outer tube are semicircular tubes, edges on the same side of the inner tube and the outer tube are welded on a same sealing board, and the inner tube and the outer tube are buckled into a round tube shape through the sealing board. Compared with the prior art, the evacuating type thermal insulation casing of the steam pipeline has the advantages of being reasonable in design, simple in structure, convenient to use and the like, thereby improving the thermal insulation effect of a steam conveying pipeline, simultaneously prolonging service life of the pipeline, reducing thermal insulation maintaining times and being easy to install.
Description
Technical field
The utility model relates to a kind of improvement technology of steam pipeline heat-insulation pipe, a kind of specifically steam line formula thermal insulation casing of finding time.
Background technique
Steam conveying pipe must be incubated in long distances process, and especially winter and north cold area are very necessary for reducing the heat loss in the course of conveying, improving thermal insulation property.Steam conveying pipe generally all is embedded in underground because be embedded in undergroundly can not take up an area of face, not influence the appearance of the city and urban planning, heat loss is low, long service life, maintenance expenses are low.In recent years, China clearly stipulates, requires municipal heating systems design " hot gas duct is walked underground ", forbids that steam line is built on stilts to lay.The thermal insulation pipe that on the directly buried type steam line, uses at present; Mainly take following method: the outside at service pipe coats two involutory semicircle thermal insulation pipes; Fix with the method for twining, the outside is wrapped one deck galvanized sheet iron again, the outsourcing one deck glass fibre reinforced plastics or the high-density polyethylene plastics that also have again.The existing deficiency of this thermal insulation pipe is: wearing out appears in the thermal insulating material of outsourcing and lapping easily, intensity reduces, the heat insulation effect variation, needs annual preservative treatment again in winter; Though the outsourcing galvanized sheet iron can improve outward appearance and corrosion resistance, in peripheral environment seasonal variations process, expand with heat and contract with cold, along with the prolongation of service time, the heat insulation effect variation; In addition, when sectional repair appearred in pipeline, the heat insulation effect of adjacent position had certain influence.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves existing technology, the formula thermal insulation casing that provides that a kind of heat insulation effect is good, working life is long, steam line that reduce the heat preservation maintenance number of times is found time.
The technological scheme of the utility model realizes by following mode; This steam line formula thermal insulation casing of finding time; Its structure comprises the inner thermal insulating layer pipe, and the outer side surface of said inner thermal insulating layer pipe covers and is fixed with a thermal insulation casing, pipe and outer tube in the structure of this thermal insulation casing comprises; The equidistant dunnage that is provided with between pipe and the outer tube in being somebody's turn to do; Cavity in said between the pipe, dunnage, outer tube is a Seal cage, above-mentioned in pipe, outer tube is the semicircle shape pipe and its homonymy edge joint weld is connected on the same shrouding, pipe in this, outer tube are all cylindrical through the shrouding make-up.
Install between the shrouding of said make-up and be provided with insulation quilt.
The width of said insulation quilt is 3-5mm.
The beneficial effect that the utility model is compared with prior art produced is:
The steam line of the utility model formula thermal insulation casing of finding time has simple in structure, easy to use, characteristics such as be skillfully constructed, and its structure has further reduced the thermal loss that transmission of heat causes owing to adopt the whole sleeve structure that vacuumizes mode; Simultaneously when the temperature variation of external environment condition the time, expanding with heat and contract with cold of technologic material is eased, the gap of thermal insulating material in the minimizing using process; The thermal insulating material of pipeline outsourcing does not directly contact with external environment condition; Reduced the influence of external corrosion; Improve the heat insulation effect of steam conveying pipe, improve working life, minimizing heat preservation maintenance number of times, the easy mounting of thermal insulation casing, have good value for applications.

Embodiment
Below in conjunction with accompanying drawing the steam line of the utility model is found time to specify below the formula thermal insulation casing work.
Shown in accompanying drawing 1, this steam line formula thermal insulation casing of finding time, its structure comprises inner thermal insulating layer pipe 6; The outer side surface of said inner thermal insulating layer pipe 6 covers and is fixed with a thermal insulation casing; Pipe 4 and outer tube 2 in the structure of this thermal insulation casing comprises, the equidistant dunnage 3 that is provided with between pipe 4 and the outer tube 2 in this, dunnage 3 is used for pipe 4 and outer tube 2 in the stretching; Weld top cover labyrinth between the end of interior pipe 4 and outer tube 2; Cavity like this between pipe 4, the dunnage 3, outer tube 2 is a Seal cage 5, above-mentioned in pipe 4, outer tube 2 is the semicircle shape pipe and its homonymy edge joint weld is connected on the same shrouding 1, pipe 4 in this, outer tube 2 are all cylindrical through shrouding 1 make-up.
Install between the shrouding 1 of said make-up and be provided with insulation quilt 7; The width of said insulation quilt 7 is 3-5mm.
The described formula thermal insulation casing of finding time adopts the galvanized sheet iron metallic material to manufacture; Described axially support plate 3 is manufactured for typing light heat insulation material piece; Whole sleeve structure meets the regulation of outsourcing galvanized sheet iron.
