Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described below.
Embodiment 1
Such as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of Novel sleeve type underground pipe, including the interior pipe 6 being coaxially disposed and outer tube 8, exhalant canal 2 is formed between interior pipe 6 and outer tube 8, it is intake tunnel 1 in interior pipe 6, the outside of interior pipe 6 is cased with instlated tubular 7, it is coaxially disposed between instlated tubular 7 and interior pipe 6, the diameter of instlated tubular 7 is more than the diameter of interior pipe 6, air heat-insulation layer 3 is formed between itself and interior pipe 6, the bottom of outer tube 8 is arranged with end socket 5, end socket 5 includes integrated socket portion 502 and sealing 501, socket portion 502 is thin wall type tubular structure, the internal diameter in socket portion 502 is slightly less than the external diameter of outer tube 8, outer tube 8 and socket portion 502 interference fit；Sealing 501 is the shell structure of arc, and it is positioned at the lower surface place in socket portion 502；One end that air heat-insulation layer matches with end socket 5 is provided with sealing lid 10, seal inner core 101 and urceolus 102 that lid 10 includes being coaxially disposed, inner core 101 and urceolus 102 are thin wall type tubular structure, the external diameter of inner core 101 is less than the internal diameter of interior pipe 6, inner core 101 is connected with interior pipe, and the internal diameter of urceolus 102 is more than the external diameter of instlated tubular 7；So, the placed cavity 103 of pipe and instlated tubular in holding just can be formed between outer wall and the inwall of urceolus 102 of inner core 101, the upper end open of placed cavity 103 also matches with interior pipe and instlated tubular 7, the lower end of placed cavity 103 seals, and the air heat-insulation layer 3 between instlated tubular 7 with interior pipe 6 is that is corresponding is positioned at placed cavity 103；In interior pipe 6, the hot water of intake tunnel 1 is entered in end socket 5 by inner core 101, rear hot water enters exhalant canal 2 internal circulation flow now due in the air heat-insulation layer 3 placed cavity 103 between inner core 101 and urceolus 102 along urceolus 102 again, " " type is for backwater channel for U in formation, effectively reduce the heat exchange into water and water outlet, reduce the loss of heat.Interior pipe 6, instlated tubular 7 and outer tube 8 adopt highdensity polyethylene or polypropylene material to make, and have higher heatproof, oil resistivity, resistance to vapour permeability and environmental stress crack resistance.
By the first dividing plate 4 and the fixing connection of second partition 9 between outer tube 8, interior pipe 6 and instlated tubular 7；nullOne end of first dividing plate 4 and second partition 9 is fixing with the inwall of outer tube 8 to be connected，The other end of the first dividing plate 4 and second partition 9 is connected through instlated tubular 7 is fixing with the outer wall of interior pipe 6，The thickness of the first dividing plate 4 and second partition 9 should be as far as possible little，Thus the impact that the current reduced in exhalant canal 2 are to dividing plate 4，First dividing plate 4 is identical with the length of outer tube 8 with the length of second partition 9，Considerably increase the first dividing plate 4 and second partition 9 and outer tube 8、Fastening force between interior pipe 6，Simultaneously，First dividing plate 4 and second partition 9 are directly through instlated tubular 7，By instlated tubular 7 and outer tube 8、Interior pipe 6 connects as a whole，Make interior pipe 6、Instlated tubular 7、More reliable with fixing of outer tube 8，Can effectively bear the active force produced between fluid，The shape of the first dividing plate 4 and second partition 9 can be rectangle、The geometry such as trapezoidal，The present embodiment adopts rectangular configuration，First dividing plate 4 and second partition 9 are centrosymmetric setting；The quantity of dividing plate can be changed according to design strength, reduces the quantity of dividing plate when ensureing bonding strength to reduce production cost as far as possible.
Seal and be fixed together also by the first dividing plate 4 and second partition 9 between lid 10 and interior pipe 6, instlated tubular 7, one end of first dividing plate 4 and second partition 9 traverse instlated tubular is connected also through fixing with inner core 101 after urceolus 102 simultaneously, which improves the job stability sealing lid 10, will not loosen because of the flowing of fluid, cause that air heat-insulation layer 3 is intake, cause cold-hot counteraction phenomenon.
For summer condition, hot water from user side enters underground pipe from intake tunnel 1, arrive after bottom underground pipe, exhalant canal 2 is entered through end socket 5, in exhalant canal 2, hot water and soil heat exchange are cooled, the hot water in intake tunnel 1 is separated by air buffer 3 with the cold water in exhalant canal 2, it is to avoid the cold-hot counteraction phenomenon between fluid.
Embodiment 2
With embodiment 1, institute the difference is that, as shown in Figure 5, first dividing plate 4 and second partition 9 are respectively equipped with several first through hole 401, several second through holes 901, first through hole 401 and the second through hole 901 are all arranged in rows, first through hole 401 and the second through hole 901 can be circular hole, square hole or other geometric holes, the present embodiment adopts circular hole, the existence of the first through hole 401 and the second through hole 901 makes will not seal between the first dividing plate 4 and second partition 9, thus the fluid of both sides also can be mutually communicated, pressure reduction will not be formed in the both sides of the first dividing plate 4 and second partition 9, decrease the compression face of the first dividing plate 4 and second partition 9, serve protective effect.
Schematically the present invention and embodiment thereof being described above, this description does not have restricted, and shown in accompanying drawing is also one of embodiments of the present invention, and actual structure is not limited thereto.So, if those of ordinary skill in the art is enlightened by it, when without departing from the invention objective, design the frame mode similar to this technical scheme and embodiment without creationary, protection scope of the present invention all should be belonged to.
