Abstract
The utility model discloses a high temperature evacuated collector tube of high life with low costs, the one end that metal internal tube is the same with the glass outer tube is all sealed, the equal opening of the other end of metal internal tube and glass outer tube, it is provided with the elastic expansion pipe to be located between glass outer tube and the metal internal tube of blind end, and install the end cover on the glass of open end outer tube, the outside of end cover is provided with pressure relief device, pressure relief device includes the inflation lid of being connected with the end cover, the inflation lid is connected with the one end of relief pipe, and the other end of relief pipe is connected with fixed lid, and be provided with the ring spring between inflation lid and fixed lid, the outside of fixed lid is connected with the end cap. This high temperature evacuated collector tube of high life with low costs, simple structure, the cost is lower, through setting up pressure relief device, can weaken glass outer tube and the metal internal tube deformation that the shrinkage produced because heat rises, prevents that the glass outer tube from breaking or taking place the leakage, great increase the life -span of thermal -collecting tube.
Description
Technical field
The utility model relates to thermal-collecting tube technical field, is specially the high-temperature vacuum heat-collecting tube of a kind of cost low high life.
Background technology
Due to the waste of resource, so countries in the world are all at searching new forms of energy, solar energy is exactly the energy of an environmental protection, and it is inexhaustible, so someone has invented solar water heater, this serves very large convenience for daily life, solar water heater absorbs heat primarily of thermal-collecting tube and carries out heat exchange, but owing to there is the coefficient of expansion difference in glass glass outer tube and metallized metal between pipe in current thermal-collecting tube, the junction that will produce pipe in glass glass outer tube and metallized metal when winter or cold weather will deform because expanding with heat and contract with cold, cause the junction of pipe in glass glass outer tube and metallized metal that leakage occurs and cause uninsulated phenomenon, also can there is breaking of glass glass outer tube in serious, make the life-span of thermal-collecting tube not high, and cost is high.
Utility model content
The purpose of this utility model is the high-temperature vacuum heat-collecting tube providing a kind of cost low high life, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: the high-temperature vacuum heat-collecting tube of a kind of cost low high life, comprise outer glass tube, the internal sleeve of described outer glass tube is provided with metal inner pipe, one end that described metal inner pipe is identical with outer glass tube is all closed, the equal opening of the other end of metal inner pipe and outer glass tube, elastic expansion pipe is provided with between the outer glass tube and metal inner pipe of blind end, and on the outer glass tube of openend, end cap is installed, the outer setting of described end cap has decompressor, described decompressor comprises the expanding lid be connected with end cap, described expanding lid is connected with one end of relief pipe, the other end of relief pipe is connected with fixed cap, and between expanding lid and fixed cap, be provided with ring spring, the outside of described fixed cap is connected with plug.
Preferably, the outer surface of described outer glass tube is provided with tempering film.
Preferably, the surface of described elastic expansion pipe is wavy.
Preferably, the inwall of described outer glass tube is provided with one-way reflecting film.
Compared with prior art, the beneficial effects of the utility model are: the high-temperature vacuum heat-collecting tube of this cost low high life, structure is simple, cost is lower, by arranging decompressor, the deformation that outer glass tube and metal inner pipe produce due to rising-heat contracting-cold can be weakened, prevent outer glass tube from breaking or leak, adding the life-span of thermal-collecting tube greatly, by arranging elastic expansion pipe, further can weaken the deformation that the rising-heat contracting-cold between interior, outer glass tube produces.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 outer glass tube, 2 metal inner pipes, 3 elastic expansion pipes, 4 end caps, 5 decompressors, 51 relief pipes, 52 expanding lids, 53 fixed caps, 54 ring springs, 6 plugs.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides the high-temperature vacuum heat-collecting tube technical scheme of a kind of cost low high life: the high-temperature vacuum heat-collecting tube of a kind of cost low high life, the high-temperature vacuum heat-collecting tube of a kind of cost low high life, comprise outer glass tube 1, the outer surface of outer glass tube 1 is provided with tempering film, and the inwall of outer glass tube 1 is provided with one-way reflecting film, one-way reflecting film can prevent light from reflecting away, increase the efficiency of heat absorption, the internal sleeve of outer glass tube 1 is provided with metal inner pipe 2, one end that metal inner pipe 2 is identical with outer glass tube 1 is all closed, metal inner pipe 2 and the equal opening of outer glass tube 1 other end, annular sealing ring is provided with between metal inner pipe 2 and outer glass tube 1, elastic expansion pipe 3 is provided with between the outer glass tube 1 and metal inner pipe 2 of blind end, the surface of elastic expansion pipe 3 is corrugated, by arranging elastic expansion pipe 3, further can weaken the deformation that the rising-heat contracting-cold between metal inner pipe 2 and outer glass tube 1 produces, and end cap 4 is installed in openend, the outer setting of end cap 4 has decompressor 5, decompressor 5 comprises the expanding lid 52 be connected with end cap 4, expanding lid 52 is connected with one end of relief pipe 51, the other end of relief pipe 51 is connected with fixed cap 53, and between expanding lid 52 and fixed cap 53, be provided with ring spring 54, expand with heat and contract with cold between outer glass tube 1 and metal inner pipe 2 occur deformation time, deformation power passes to expanding lid 52 by end cap 4, power is passed to ring spring 54 by expanding lid 52, thus deformation is eliminated, by arranging decompressor 5, the deformation that outer glass tube 1 and metal inner pipe 2 produce due to rising-heat contracting-cold can be weakened, prevent outer glass tube 1 from breaking or leaking, add the life-span of thermal-collecting tube greatly, the outside of fixed cap 53 is connected with plug 6, plug 6 is used for fixing fixed cap.
Operation principle: during use, the temperature difference extraneous and inner when thermal-collecting tube is larger, when there is deformation between outer glass tube 1 and metal inner pipe 2, deformation power passes to expanding lid 52 by end cap 4, power is passed to ring spring 54 by expanding lid 52, thus deformation is eliminated, the pipe of elastic expansion simultaneously 3 also can slacken deformation further.
