Abstract
The invention relates to a heat preservation tile, which comprises an inner tile shell and an outer tile shell which are respectively composed of an upper tile shell and a lower tile shell, and is characterized in that the inner surface and the outer surface of the tile shell respectively form a continuous inner convex-concave structure and a continuous outer convex-concave structure, and a certain matching relation and a certain size relation are met, so that when the heat preservation tile is continuously buckled, the front tile and the rear tile are mutually buckled or are mutually buckled with two inner tile shells which are connected with the front tile and the rear tile through the outer tile shell, the corresponding buckled interface of the upper tile shell and the lower tile shell can be a plane or an inclined plane, and the upper tile and the lower tile shell can be provided with an upper concave-lower convex structure, thereby having the effects of preventing an axial heat dissipation gap and preventing liquid from entering the.
Description
Technical field
The present invention relates to be used for pipe or the adiabatic device of piping, relate in particular to a kind of prevent to produce axial heat radiation gap and the insulation tile that prevents liquid entering pipeline surface.
Background technique
Existing insulation tile for energy-conservation, adopts one save symmetrical half-watt and be buckled in up and down and block heat bridge or cold bridge on the pipeline, reaches heat insulation or separated cold purpose.Its deficiency is: because the coefficient of thermal expansion and contraction of insulation tile is different with pipeline; Usually produce the pipeline swell increment produces axial slits greater than the swell increment of insulation tile phenomenon, also usually produce pipeline shrinkage amount greater than cold insulation watt and make cold insulation watt compressed phenomenon.Like caliber is DN350, the pipeline of 1000 meters of length, 550 ℃ of serviceability temperatures, and normal temperature (like 20 degree) is down by dress; About 7.5 meters of swell increment after coming into operation, the insulation tile swell increment is about 1.5 meters, and then the exposed length of pipeline is 6 meters; 15 ℃ of considerations of environment mean temperature per year, its thermal loss is 25746.73W
Its another deficiency is: insulation tile shell radial end face is a level, and its water proofing property is bad, and water can be in end face flow ipe watt shell, thereby accelerates Corrosion of Pipeline.In addition, the existence of liquid on tube wall can be taken away energy.
ZL200620093712.3 discloses a kind of waterproof thermal-insulated watt, has solved the problem of radially intaking, but the water inlet problem between the unresolved adjacent insulation tile slit.
Summary of the invention
In view of the above-mentioned deficiency of existing in prior technology, the present invention aims to provide a kind of insulation tile that prevents to produce axial heat radiation gap and prevent liquid entering pipeline surface that has.
Technical solution of the present invention is achieved in that
A kind of insulation tile; Comprise internal tile shell and external tile shell; Said internal tile shell and external tile shell are to be fastened by two part watt shells up and down respectively and the tubular structure of the hollow that forms, it is characterized in that having on the said internal tile shell an above outer ring groove, form continuous outer convex-concave structure; Annular groove in having more than one on the said external tile shell forms continuous interior convex-concave structure; Said outer ring groove and interior annular groove are coaxial with the tubular structure of said internal tile shell and external tile shell respectively;
The external diameter of the outer convex section of said internal tile shell tubular structure and the internal diameter of said interior annular groove form Spielpassung or transition fit; Projecting inward section the internal diameter of said external tile shell tubular structure and the external diameter of outer ring groove form Spielpassung or transition fit; Then when said insulation tile fastened continuously, said external tile shell buckled with two internal tile shells that head and the tail link simultaneously each other;
The axial length of said each outer convex section of internal tile shell is respectively less than the axial length of annular groove in corresponding each section of said external tile shell; Less than the axial length of corresponding each section outer ring groove of said internal tile shell, its residual quantity is not less than corresponding said insulation tile and is buckled in the poor of its interior the expand with heat and contract with cold amount of pipeline under the pipeline operating temperature each axial length of projecting inward section of said external tile shell respectively.
Generally, outer watt intensity is high, is not easy to tramp; Neva intensity is low, and its thermal conductivity is low accordingly, thereby has guaranteed heat insulation effect.
Two corresponding separating surfaces that fasten of part watt shell up and down of described internal tile shell and/or external tile shell can be the planes, also can be the inclined-plane, and the inclined-plane are low inside and high outside.
The groove and the convexity that axially connect and/or connect along its radially outward along it are arranged respectively on the corresponding separating surface that fastens of watt shell of two parts up and down of said internal tile shell and/or external tile shell; Be that top watt shell has the groove that axially connects and/or connect along its radially outward along it on its separating surface; Corresponding, bottom watt shell has the convexity that axially connects and/or connect along its radially outward along it on its separating surface.
The excircle of the tubular structure of said internal tile shell and/or external tile shell is provided with the hoop groove that is used for fixing, and cooperates spring clamp, steel band or buckle to fix.
The interior annular groove of the bottom of said external tile shell watt shell below has a weep hole perpendicular to ground.
The interior annular groove of the bottom of the said external tile shell watt shell internal surface of below axially has a drainage groove along it, and the two ends of said drainage groove are connected to the both sides of interior annular groove of the bottom watt shell of said external tile shell respectively.
Compared with prior art, beneficial effect of the present invention is following:
The design of the disclosed insulation tile of the present invention has concurrently and prevents to produce axial heat radiation gap and prevent that liquid from getting into the effect of pipeline surface.In heat preservation energy-saving, insulation tile produces the thermal loss that axial clearance causes when having avoided heat expansion, prevents and alleviated the possibility of inflow insulation tile inwalls such as rainwater, snow-broth and condensed water simultaneously effectively; Thereby slowed down Corrosion of Pipeline, improved working life, reduced maintenance cost; Saved installation cost, avoided liquid inflow tube wall and increased energy consumption, thereby brought better economic benefit; In addition, can save the on-the-spot cost expenditure that the outer galvanized sheet iron of watt shell is installed, easy for installation.
