Description
Technical field
The present invention relates to conveying equipment for fluid substances technical field, be specifically related to a kind of long distance vacuum insulation conveyance conduit.
Background technique
At present, the gas line network of rock gas not yet covers all regions, some non-pipe networks areas in the suburb in such as city and rural area etc., need the supply technology adopting compressed natural gas, be transported to non-pipe network region by after natural gas compressing by Special type transportation vehicle, then use being transferred to each user after natural gas depressurization.In the process discharged by compressed natural gas pressure-reducing gas, rock gas can need to draw amount of heat, causes the temperature of natural-gas to decline.In the delivery application standard of gas distributing system, ducted natural gas temperature generally can not lower than-4 DEG C, simultaneously because the pipeline of gas distributing system often adopts the steel pipe containing carbon element, because it can show fragility at low temperatures, so operating temperature can not lower than-20 DEG C.So in the prior art, normal employing arranges heating equipment in natural gas relief device, before carrying out pressure adjusting to rock gas, first heats to it, makes the rock gas exported after decompression can meet the transmission requirement standard of gas distributing system.Its shortcoming is, in natural gas relief device, heating equipment is set, need additionally to provide a large amount of heat energy electric power to work on request to make heating equipment, thermal source has electric power, also there is hot water etc., cause a large amount of energy consumptions, improve cost of production, device for simultaneous heating its need to arrange a series of auxiliary facilities such as power distribution station, the wasting of resources is caused to the design and construction of Production Regional.
Oil is in oil recovery process, because oil is too high containing cured amount, carry oil concentration large, often cause oil transport pipeline oil transportation difficulty, especially in cold season, heating on petroleum pipeline is needed to solve the problem of oil transportation difficulty, existing electric heater for petroleum pipeline is generally be arranged on petroleum pipeline outer wall, and petroleum pipeline is in order to be incubated, often petroleum pipeline many employings inner core, thermal insulation layer and urceolus, although the setting of thermal insulation layer can reduce scattering and disappearing of the interior oil heat of pipe, but heat insulation effect is not good enough, and it is not corrosion-resistant, working life is short, particularly general inside and outside two-tube between, namely also need between outer tube body internal surface and interior tube body outer surface to set up necessary safeguard structure, to rectificate stability far away later.
With steam during industrial enterprise produces, hot water, in the engineerings such as cities and towns central heat supplying, conveyance conduit one adds external thermal insulation by hot fluid steel pipe and wraps up with glass cloth, thermal insulation layer adopts comparatively single thermal insulating material, the thermal insulation property of the thermal insulating material usually chosen is not good, in order to can the high temperature of steam medium in resistance to pipeline, must ensure that the thickness of thermal insulation layer is enough large, thus cause outside protective pipe diameter needs to strengthen accordingly, cause the raising of cost, and thermal insulation layer is low for service life, through being exposed to the sun, high temperature, the reasons such as rain erosion can cause thermal insulation layer to come off, thus the thermal insulating material causing the cost of maintenance maintenance higher and discarded also can to environment.The foaming of another kind high-density polyethylene external protective pipe, rigid poly urethanes is thermal insulation layer and fluid steel pipe composition, triplicity becomes an entirety closely, although certain heat insulating effect can play in this mechanism, but in course of conveying, the consume of heat is still a large amount of scatters and disappears, and this heat loss is not only distributed by conveyance conduit itself.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, provide a kind of long distance vacuum insulation conveyance conduit, high insulating effect, installation and maintenance are conveniently, cost is lower, the life-span is long, can the various cold fluid and hot fluid of long-distance sand transport.
The present invention is the deficiency solved the problems of the technologies described above, the technological scheme adopted is: a kind of long distance vacuum insulation conveyance conduit, described conveyance conduit is in series by multiple piping unit, piping unit comprises interior pipe, outer tube and annular seal head, described interior pipe is located in outer tube, and setting is stretched out from outer tube in the two ends of interior pipe, annular seal head is set in two external parts of interior pipe, the inner ring of annular seal head and outer shroud are tightly connected with inner and outer tubes respectively, and annular seal head offer multiple vent; The interior seal of tube docking of adjacent two piping units, and joint is arranged with adapter sleeve, the two ends of adapter sleeve are tightly connected with the outer tube of two piping units respectively, multiple piping units of conveyance conduit are arranged at intervals with the vacuum pump connecting head be communicated with interlayer between the internal layer of its piping unit and skin.
Temperature in order to avoid inner and outer tubes is different and cause body to expand with heat and contract with cold to be cracked by weld bond, outer tube is provided with multiple bellows segment, the thermal stress change that reply body causes due to temperature variation.
Because body is longer, be provided with spacer dimple ring in interlayer between the inner and outer pipe sections, spacer dimple ring is equivalent to a support ring, stablizes the spacing between inner and outer tubes.
In order to isolated heat radiate in pipe, the outer wall of interior pipe is also provided with antiradiation separation layer, this antiradiation separation layer can be aluminium foil or cellophane.
beneficial effect
Fluid-transporting tubing of the present invention is made up of multiple piping unit, actual fed requirement complicated and changeable can be met, each piping unit all has vacuum sandwich, and the vacuum sandwich of whole piping units after series connection is interconnected, this vacuum sandwich keeps its degree of vacuum by spaced vacuum pump, there is high insulating effect, installation and maintenance are convenient, cost is lower, the life-span is long, can the advantage of the various cold fluid and hot fluid of long-distance sand transport.
