Abstract
The invention discloses a solar vacuum heat collecting pipe with screw threads at the pipe opening, and a connecting device thereof, belonging to the field of solar photo-thermal utilization, and consisting of an outer wall and an inner wall of the vacuum heat collecting pipe, the screw threads at the pipe opening, a screwed end cover, a sealing rubber ring and a guide pipe. The invention is characterized in that during the sintering of the pipe opening part of the vacuum pipe, the plasticity of glass at high temperature is utilized to form necking pressed threads on the outer wall of an outer pipe opening of the vacuum pipe, thus forming the external screw threads of the pipe opening; the screwed end cover is reliably connected with the vacuum pipe by screws, the sealing between the end cover and the vacuum heat collecting pipe is realized by the sealing rubber ring, the screwed end cover is integrated or welded with the homogenous guide pipe, and the guide pipe can be produced into unitized pipe units with different specifications and models. The solar vacuum heat collecting pipe solves the problem of non-bearing of silica gel sealing, improves the bearing property of the solar system, and can realize free and quick connection between the vacuum pipes as well as between the vacuum pipe and other pipelines. The vacuum pipe is not inserted into a case, thus completely utilizing the effective heating length of the vacuum pipe, and simultaneously realizing the close arrangement and installation of the vacuum pipes and increasing effective heat collecting area.
Description
Technical field:
The invention belongs to solar energy heat utilization field, relate to a kind of evacuated solar collecting tube of mouth of pipe band screw thread and connect jockey, it can be widely used in solar water heater, solar energy housing heating, solar energy drying and other Solar Energy Heat Utilization System.
Background technology:
At present, solar utilization technique more and more comes into one's own, vacuum heat collection pipe is owing to can solve heated medium well and extraneous heat convection and heat dissipation problem, Heat-collecting effect is good, in solar water heating system, be widely used, but traditional vacuum tube in use, thermal-collecting tube and header be connected sealing all adopt the elasticity that relies on sealed silicon cushion rubber self and and vacuum tube between frictional force seal heat transfer medium, when heat transfer medium pressure increases, can produce the length travel of leakage problem and vacuum tube, in addition, use the silica gel circle also need regularly replace, cause the inconvenience of use.On the other hand, because this installation and sealing means must leave enough gaps between vacuum tube, simultaneously, vacuum tube must stretch into the certain distance of header could guarantee the sealing installation, thereby causes under the identical daylighting area, and collector area reduces.For addressing this problem, the utility model of number of patent application 97229406.6 has proposed a kind of solar energy vacuum tube seal nipple, it is characterized in that being connected vacuum tube and header inner housing by the seal nipple that a cover is made up of sealing ring, nut, adapter sleeve and sealing gasket, reduce vacuum tube and stretched into the interior length of header, increased effective collector area.But this utility model structure and installation relative complex are difficult for implementing.
Summary of the invention:
Main purpose of the present invention provides a kind of evacuated solar collecting tube and jockey thereof of mouth of pipe band screw thread, not only solve vacuum tube silica gel sealing not pressure-bearing and the big problem of tube pitch, but also can realize reaching between the vacuum tube being connected fast arbitrarily of vacuum tube and other pipelines.
The vacuum heat collection pipe of this mouth of pipe band screw thread and jockey thereof are by vacuum heat collection pipe outer wall (1), vacuum heat-collecting inside pipe wall (2), vacuum heat collection pipe mouth of pipe screw thread (3), and and the matching used thread ending cover of vacuum heat collection pipe mouth of pipe screw thread (4), O-ring seal (5) and mozzle (6) formation.The evacuated solar collecting tube that it is characterized in that the one or both ends opening is when the spout part sintering, plasticity when utilizing glass high temperature, in vacuum tube outer tube mouth of pipe outer wall reducing rolled thread, form mouth of pipe male thread (3), by spiral connection reliably between screw thread and the thread ending cover (4), with the sealing between O-ring seal (5) realization end cap and the vacuum heat collection pipe, thread ending cover (4) is made of one or welds with homogeneity mozzle (6), and mozzle (6) can be made the complete pipe fitting of different size model.Thereby avoid glass and the unmatched difficult point of other materials linear expansion coefficient, solved not pressure-bearing problem of silica gel sealing, improve the pressure-bearing property of solar energy heat distribution system, can realize reaching between the vacuum tube being connected fast arbitrarily of vacuum tube and other pipelines simultaneously.
The present invention has the manufacturing process that sealing is reliable, quick and easy for installation, simplified the header that is attached thereto, because and the connected mode of header changes, vacuum tube does not insert in the case, utilized effective heated length of vacuum tube fully, simultaneously, realize the solid matter installation of vacuum tube, can reduce the tube pitch that vacuum tube is installed significantly, increase collector area 22%.

1, vacuum heat collection pipe outer wall; 2, vacuum heat-collecting inside pipe wall; 3, vacuum heat collection pipe mouth of pipe screw thread; 4, thread ending cover; 5, O-ring seal; 6, mozzle.
The specific embodiment:
As shown in Figure 2, the vacuum heat collection pipe openend is when the spout part sintering, utilize the high temperature plasticity of glass, in vacuum tube outer tube outer wall reducing rolled thread, form mouth of pipe external screw thread (3), by being threaded reliably between screw thread and the thread ending cover (4), with the sealing between O-ring seal (5) realization end cap and the vacuum heat collection pipe, thread ending cover (4) is made of one or welds with homogeneity mozzle (6).Bearing operation (1.0Mpa pressure experiment) under the warm operating mode in can realizing (〉=100 ℃); Mozzle (6) can be made different model and specification pipe fitting, can realize reaching between the vacuum tube being connected fast arbitrarily of vacuum tube and other pipelines.This connected mode can make up the building element type solar heat collector of architecture-integral, is widely used in fields such as solar water heating system, solar energy drying, solar airconditioning refrigeration.
