Description
Technical field
The straight-through thermal-collecting tube mechanically-sealing apparatus of high temperature relates to the solar energy utilization technique field in a kind of
Background technology
At present the patent documentation of relevant straight-through thermal-collecting tube has a lot, its basic structure all be with metal tube as endothermic tube, outer cover clear glass outer tube, and be the vacuum insulation space between the pipe.The pipe two ends are the metal connector, carry out the hot melt sealing-in of glass and metal by kovar alloy, perhaps with adhesive seal,, on metal tube or glass outer tube, be connected with expansion joint in order to compensate the stress that metal tube and the linear expansion of glass outer tube after the intensification causes different generations.
Theory and technology scheme from above-mentioned patent documentation is seen in the time of implementing and is relatively easy to.But at present tens families are arranged in enterprise and the unit that the time order and function in nearly ten years is researched and developed this straight pipe.Or heatproof is low or service life short, many deficiencies such as quality instability, none successful commercialization.Its key issue is because metal tube and the expansion of two kinds of materials of glass outer tube cause differently, shrinks that vacuum seal destroys easily in the frequent alternately dynamic stress variation expanding.This has proposed very high making precision techniques requirement for the vacuum seal between metal and the glass outer tube.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of technology simple, scientific and reasonable, be convenient to the industrialization Assembling Production, sealing effectiveness is long-acting lasting, steady quality, stable performance, the straight-through thermal-collecting tube sealing device of high temperature during the alternately dynamic stress variation destruction that can not shrink because of expanding is vacuum-packed.
The technical scheme that its technical problem that solves the utility model adopts is: the straight-through thermal-collecting tube mechanically-sealing apparatus of high temperature in a kind of, comprise metal tube, metal tube is with the glass outer tube outward, it is characterized in that: described glass outer tube two ends have the glass flange of outward flanging, be with annular locking card at glass outer tube two ends, locking card and glass flange near, be added with gasket seal therebetween, added the U-shaped connector at locking card and glass flange, the U-shaped connector is threaded with the locking card, leave the expansion clearance between U-shaped connector and the glass end face of flange, be added with gasket seal between U-shaped connector and the glass flange side.
When the glass outer tube is made up of two or two above axially-aligned, be added with H shape connector between adjacent two glass outer tubes, H shape connector both sides are connected with annular locking card respectively, annular locking is fastened in outside the glass outer tube, H shape connector leaves the expansion clearance respectively and between the glass end face of flange of glass outer tube, is added with gasket seal between H shape connector and the glass flange side.The connector of H shape connects the glass outer tube, can play the effect of support fixation, makes whole device more firm.
The beneficial effect that the utility model had is: technology is simple; scientific and reasonable; be convenient to the industrialization Assembling Production, sealing effectiveness is long-acting lasting, steady quality; stable performance; the alternately dynamic stress that is difficult for shrinking because of expanding destroys vacuum seal, when long tube connects more stable firmly, can better the cover glass outer tube;, be widely used for the solar groove type power field.

Fig. 2 is two of a structural representation of the present utility model;
Wherein: 1, U-shaped connector; 2, locking card; 3, glass outer tube; 4, gasket seal; 5, metal tube; 6, glass flange; 7, H shape connector; 8, gasket seal
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As Fig. 1, the straight-through thermal-collecting tube mechanically-sealing apparatus of high temperature in a kind of, comprise metal tube 5, the metal tube 5 outer glass outer tubes 3 that are with, described glass outer tube 3 two ends have the glass flange 6 of outward flanging, be with annular locking card 2 at glass outer tube 3 two ends, locking card 2 and glass flange 6 near, be added with gasket seal 4 therebetween, outside locking card 2 and glass flange 6, be added with U-shaped connector 1, U-shaped connector 1 is threaded with locking card 2, leaves the expansion clearance between U-shaped connector 1 and glass flange 6 end faces, is added with gasket seal 8 between U-shaped connector 1 and glass flange 6 sides.Gasket seal 4 and 8 also has heat-insulating bridge-cut-off effect and the effect of buffering stress etc. except that sealing function is arranged.Metal tube 5 penetrates flanged (FLGD) glass outer tube 3 after putting into getter, and metal tube 5 is inserted in the same circular centre hole of U-shaped connector 1 then.The moulding one-tenth of glass outer tube 3 two ends glass high temperature melting is to the glass flange 6 that turns up, and the outside is with the screw-threaded coupling card 2 of annular, between locking card 2 and the glass outer tube 3 gasket seal 4 is arranged.Locking card 2 screws in connector 1 screw thread the glass flange is clipped between U-shaped connector 1 and the locking card 2 tightly admittedly.Glass flange 3 is fitted with 1 sealing of U connector.Glass flange 3 is fixed with U-shaped connector 1 inner mechanical grip by annular locking card 2.In the middle of U-shaped connector 1 and the glass flange 3 gasket seal 4 is arranged.Connector penetrates the back welded seal with the middle circular hole of circle at metal tube 5, on U type connector 1 steam vent is arranged, and between metal tube 5 and the glass outer tube 3 getter is arranged.The straight-through thermal-collecting tube that assembles carries out high-temperature exhaust air and getter is activated air to be expanded bleed up to-6MPa vacuum under 400 degrees centigrade and get final product.After the exhaust steam vent sealing can be finished production process.
As Fig. 2, when glass outer tube 3 is made up of two or two above axially-aligned, be added with H shape connector 7 (being equivalent to the opposite U type connector of both direction) between adjacent two glass outer tubes 3, H shape connector 7 both sides are connected with annular locking card 2 respectively, annular locking card 2 is enclosed within outside the glass outer tube 3, H shape connector 7 leaves the expansion clearance respectively and between glass flange 6 end faces of glass outer tube 3, is added with gasket seal 8 between H shape connector 7 and glass flange 6 sides.H shape connector 7 connects glass outer tube 3, can play the effect of support fixation, makes whole device more firm.
Can daub into encapsulant in the screw thread of locking card 2 or H type connector 7 inside threads to improve sealing characteristics.There is not polar fibers etc. as refractory seals glue flexible metal band.
Because adopt mechanical seal not only structural strength height, high temperature resistant, long service life.Cooling constantly produces the expansion shrinkage when heating up; connect the phenomenon that does not produce stress between first-class metalwork and the glass outer tube and make the fragmentation of glass outer tube; and technology is simple; scientific and reasonable; be convenient to the industrialization Assembling Production, sealing effectiveness is long-acting lasting, steady quality; stable performance because the existence of H type connector when long tube is connected more stable more firm can better the cover glass outer tube.
