Abstract
The utility model provides an energy-saving vacuum sealing device which comprises an outer protective steel pipe wrapped on the outer periphery, an outer protective steel pipe annular plate, an operating steel pipe annular plate sleeved onto an operating steel pipe, a fixing plate and a seal compensator. The operating steel pipe annular plate is abutted against one end of the seal compensator, and the outer protective steel pipe annular plate is sleeved onto the seal compensator and closely connected with the outer periphery of the outer protective steel pipe. The energy-saving vacuum sealing device has the advantages that the problem of partition during pipeline vacuuming is solved while the cold bridge problem and the operating pipe compensation problem can be solved. Moreover, the energy-saving vacuum sealing device has the advantages of effectiveness in sealing, simple structure, convenience in mounting, convenience and rapidness in maintenance, energy conservation, environment protection, attractiveness and the like.
Description
Technical field
The utility model belongs to steam insulation pipeline pipe fitting field of sealing technology, especially relates to a kind of energy-saving vacuum seal arrangement.
Background technique
Generally in existing technology adopt traditional direct-burried vapour system, have that engineering cost is low, good insulating, long service life, occupation of land less, characteristics such as fast, the environmental protection of construction and safety, become pipework design and construction indispensable material.But there is more technical problem in the direct-buried steam pipeline of domestic present production; Do not reach requirement, fixed support, guiding trestle employing rubber thermal-protective material like its Corrosion Protection; There is serious aging and cold bridge problem or the like; These problems affect the normal operation and the use of pipeline, restricted the application and the popularization of direct-buried steam pipe laying technology.
Summary of the invention
The problem that the utility model will solve provides a kind of prefabricated direct-buried steam insulation pipe vacuum system, relates in particular to the seal arrangement of this vacuum system being realized sealing.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of energy-saving vacuum seal arrangement is provided, comprises being wrapped in peripheral external protective steel tube, external protective steel tube ring flat-plate; And be enclosed within the working steel tube ring flat-plate on the working steel tube; Fixed plate and sealing compensation device, said working steel tube ring flat-plate and said sealing compensation device one end are close to, and said external protective steel tube ring flat-plate is enclosed within on the sealing compensation device and with said external protective steel tube excircle and closely is connected.Be provided with vent panel in the said external protective steel tube, said vent panel is provided with exhaust port.Said sealing compensation device is a corrugated expansion joint.Said working pipe ring flat-plate and said vent panel are close to, and said work ring flat-plate is lived said exhaust port one side seal, and it is sealed.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, pipe insulating layer can be realized vacuumizing, but the water vapor in the discharge conduit outer and inner tube cavity like this; At first avoid Corrosion of Pipeline; Reduce ducted convection heat exchange simultaneously, reduced the thermal loss of pipeline, improved the thermal efficiency of heat supply network; And then reduced the temperature on external protective steel tube surface, under equal insulation thickness, reduce by 8～13 ℃ of outside wall temperatures than air layer structure.In addition, pipeline realizes that vacuum just need not be provided with the humidity discharging pipe, has reduced the damage percentage of outer sleeve, makes pipeline more attractive in appearance along the line.The applicating energy-saving vacuum sealing device can solve the partition problem that pipeline vacuumizes in prefabricated direct-buried steam insulation pipeline; Can solve the compensation problem of cold bridge problem and working pipe again, have good sealing effect, simple in structure, easy for installation, convenient, energy-conserving and environment-protective of maintenance, advantage such as attractive in appearance.

Embodiment
As shown in Figure 1, the energy-saving vacuum seal arrangement of the utility model comprises external protective steel tube 3, external protective steel tube ring flat-plate 6, and be enclosed within working steel tube ring flat-plate 4, fixed plate 7 and the compensator 2 on the working steel tube 1.Fixed plate 7 is fixing with the welding of external protective steel tube 3 inwalls, and working steel tube ring flat-plate 4 one ends and compensator 2 are close to, and with the compensator port sealing, the other end and fixed plate 7 are close to realizes the location.Working steel tube ring flat-plate 4 is lived said exhaust port 5 one side seals, and it is sealed.External protective steel tube ring flat-plate 6 is enclosed within on the compensator 2 and with external protective steel tube 3 excircles and compensator 2 excircles and welds, and realizes the sealing between two steel pipes, and with the segmentation of pipeline vacuum layer.Fixed plate 7 be provided with working steel tube 1 and external protective steel tube 3 between the exhaust port 5 that communicates of space, when equipment when exhaust port is bled, vacuum is pumped in the space that working steel tube 1 and external protective steel tube are 3.Compensator 2 is a corrugated expansion joint, and the quantity of bellows and length are confirmed after will passing through and calculating.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
