Description
Technical field
The present invention relates to the improvement structure of a kind of slot light collection solar energy with straight through heat collecting vacuum tube connector, simplified on-the-spot installation effectiveness, improved the reliability of installing.
Background technology
The structure that tradition is used for the light-concentrating solar heat-collection vacuum tube is inside and outside two-layer, and internal layer is the metal tube of oily medium, and the skin that is contained within metal tube is glass tube, and the end that is connected to each other of glass tube and metal tube carries out vacuumizing after adhering and sealing at the construction field (site).Existing adhering and sealing method is to adopt at the wherein metal tube at position, two a metal tube butt ends end of welding bellows radially, and the other end of bellows be included in the glass tube welding of another metal tube after form sealing and it vacuumized, become vacuum tube.Be subjected to cold and hot flexible expansion in atmosphere when metal tube after, regulate the damage of avoiding glass tube by bellows.In addition, while also due to traditional glass tube with vacuum, with metal tube, being connected, the welding at two positions is carried out at the needs scene, this has more increased the difficulty of construction,, as bellows and metal tube, glass tube welding to each other, also will punch and vacuumize hot-melting sealed glass tube after welding.Therefore, have an installation effectiveness low, poor reliability, also can have influence on service life simultaneously.
Summary of the invention
In view of above-mentioned present situation, the invention provides a kind of slot light collection solar energy with straight through heat collecting vacuum tube connector, carry out fast straight cutting by the heat collecting vacuum pipe connector and connect, eliminated the job site welding sequence, have installation effectiveness, reliability is high, it is convenient safeguard to change.
Technical solution of the present invention is: a kind of slot light collection solar energy straight through heat collecting vacuum tube connector, comprise pipe joint, this pipe joint center has the through hole for the grafting metal tube, be positioned at the annular blind hole that axially has the grafting glass tube of through hole periphery along the two ends of pipe joint, also comprise on through hole and annular blind hole and be separately installed with sealing ring, be provided with two at pipe joint staggered position radially and vacuumize hole, this vacuumizes hole and communicates with annular blind hole, and is arranged on the described sealing-plug that vacuumizes in hole.During installation, forms in metal tube is inserted the through hole of sealing along the pipe joint two ends respectively and be tightly connected, then glass tube is inserted and seals in annular blind hole, make glass tube inside airtight, mutually UNICOM not.After glass tube vacuumizes, will vacuumize the hole sealing.
In the present invention, the related interior sealing ring of annular blind hole that is arranged on pipe joint, be mounted on the outer shroud of annular blind hole, or be arranged on interior ring.
In the present invention, mentioned pipe joint is to adopt metal material or nonmetallic materials to make.
Further, also be included in the through hole of pipe joint and be provided with collet.Insert in collet by metal tube like this, avoid the heat conduction.
In a word, slot light collection solar energy provided by the invention straight through heat collecting vacuum tube connector, have that project organization is simple, cost of manufacture is low, install job site, change that convenient, fast efficiency is high, connected mode is safe and reliable, and help to improve service life.
Description of drawings
Fig. 1 is topology view of the present invention;
Fig. 2 is another embodiment of Fig. 1.
The specific embodiment
Embodiment is further described the present invention below in conjunction with accompanying drawing.
Slot light collection solar energy shown in Figure 1 straight through heat collecting vacuum tube connector, comprise and adopt the compressing pipe joint 1 of nonmetallic materials, there is a through hole 6 at this pipe joint 1 center, by the two ends of through hole 6, inserts metal tube 7, makes metal tube 7 two ends of insertion leave one section distance of stretch out and draw back.This metal tube 7 is for conducting oil medium, so the three seals circle 8 for sealed metal tube 7 is installed on through hole 6.In the present invention, two ends along pipe joint 1 are positioned at the annular blind hole 3 of axially having of through hole 6 peripheries,, along annular blind hole 3 two ends grafting glass tubes 5, install while coordinating and relate to equally sealing problem, and the two seals circle 4 of sealed glass tube 5 is installed on the external diameter of annular blind hole 3.The outside that is positioned at glass tube 5 of sealing circle 4.In addition, will form vacuum tube after glass tube 5 is installed, therefore, two that are provided with at described pipe joint 1 staggered position radially vacuumize hole 2, and this vacuumizes hole 2 and communicates with annular blind hole 3, and annular blind hole 3 is communicated with glass tube 5.Therefore, after glass tube 5 and pipe joint 1 are installed, by at two, vacuumizing 2 places, hole, vacuumize, after glass tube 5 forms vacuum, by sealing-plug 9, with two, vacuumize hole 2 sealings.
In the present invention, mentioned pipe joint 1 except adopting nonmetallic materials, can also adopt metal material to make.
In addition,, except above-mentioned road sealing ring 4 is arranged on the external diameter of annular blind hole 3, two seals circle 4 can also be arranged on the internal diameter of annular blind hole 3, like this, make sealing ring 4 be positioned at the inboard of glass tube 5.
The connector tube joint 1 of above-described embodiment adopts nonmetallic materials as once compressing in the bakelite composite.During installation, the interior insertion heat absorption of centre through hole 6 metal tube 7, by sealing ring 8 sealings, make metal tube 7 inner airtight not with outside UNICOM, in the annular blind hole 3 that glass tube 5 inserts with sealing ring 4, make glass tube 3 inner airtight, inside and outside not UNICOM, vacuumize and form negative pressure and namely complete and be connected and installed by vacuumizing hole 2 finally.Can save the Site Welding operation, have and connect simply, installation effectiveness is high, and reliability is high, and cost is low, safeguards the characteristics easily of changing.
Fig. 2 has provided another example structure of Fig. 1.It is to have done corresponding variation on the architecture basics of Fig. 1.What it was different from Fig. 1 is to be provided with collet 10 in the central through hole 6 of described pipe joint 1.This kind mode is mainly to be to adopt metal material to make for pipe joint 1.The effect of this collet 10 is to avoid between the pipe joint of metal tube 7 and metal 1 forming the heat conduction, and glass tube 5 is brought adverse influence.
