Abstract
The utility model relates to a double-way circulating vacuum glass heat collecting pipe, which comprises an inner glass pipe, an outer glass pipe, a connecting sleeve, a small screw cover and a big screw cover, wherein the connecting sleeve is connected with the left ends of the inner glass pipe and the outer glass pipe or the right ends of the inner glass pipe and the outer glass pipe, wherein the small screw cover and is tightly connected with the left end of the connecting sleeve through a small O-shaped ring which is tightly sheathed on the inner glass pipe. The left end of the outer glass pipe is butted with a boss which is arranged in the middle of the connecting sleeve, and the big screw cover is tightly connected with the right end of the connecting sleeve through a big O-shaped ring which is tightly sheathed on the outer glass pipe. A vacuum layer is arranged between the inner glass pipe and the outer glass pipe. The double-way circulating vacuum glass heat collecting pipe of the utility model has the advantages of convenient operation and installation, low cost, safety, no explosion of pipes, high thermal efficiency, etc.
Description
1, technical field
The utility model relates to evacuated solar collecting tube, specifically a kind of bilateral circulating vacuum glass heat collection tube.
2, background technology
Existing evacuated solar collecting tube is divided into two classes, one class is the full glass solar vacuum heat collection pipe, one class is exactly a glass metal structure thermal-collecting tube, because glass metal structure thermal-collecting tube is made up of glass outer tube and metal inner pipe, with respect to the full glass solar vacuum heat collection pipe, cost increases, technology is numerous and diverse, operation increases, and the full glass solar vacuum heat collection pipe can also be divided into two kinds of single-pass and bilaterals, the evacuated solar collecting tube of single-pass since water inlet and water outlet all at one end, Hot swapping efficient is very low, the use of also can't connecting easily produces dirt, not easy-clear on the inner tube wall, make troubles to the user, and existing bilateral evacuated solar collecting tube, the two ends of interior pipe respectively with the two ends sealing-in of outer tube because glass is fragile material, interior pipe causes bursting of thermal-collecting tube easily because of the length variations that expansion causes, and when being connected with casing with any pipeline, not easy to operate, connect very built on the sand with firm.
3, summary of the invention
Technical assignment of the present utility model provides a kind of bilateral circulating vacuum glass heat collection tube, effectively solved the low and bilateral pipe bombing of the single-pass pipe thermal efficiency in the prior art, has been difficult for the defective of attaching.
The technical scheme that its technical problem that solves the utility model adopts is: bilateral circulating vacuum glass heat collection tube, structure comprises inner glass tube, outer glass pipe, adapter sleeve, minor thread lid and major thread lid, interior, the left end of outer glass pipe is or/and right-hand member is connected with adapter sleeve, wherein at left end, minor thread lid closely is connected the left end of adapter sleeve by tightly being enclosed within little O type circle on the inner glass tube, the left end of outer glass pipe withstands on the boss place in the middle of the adapter sleeve, major thread lid closely is connected the right-hand member of adapter sleeve by tightly being enclosed within big O type circle on the outer glass pipe, is vacuum layer between inner glass tube and the outer glass pipe.The setting of little O type circle, make inner glass tube and adapter sleeve tighten together, sealing is very good, the two ends of outer glass pipe withstand on the boss place in the middle of the adapter sleeve, major thread lid is connected the right-hand member of adapter sleeve by tightly being enclosed within big O type circle on the outer glass pipe, in like manner, outer glass pipe and adapter sleeve also are closely linked, and the adapter sleeve of solar vacuum glass thermal-collecting tube by two ends makes and self install more easily and place.
Bilateral circulating vacuum glass heat collection tube of the present utility model is compared with prior art, has easy to install and use, characteristics such as cost is low, safe pipe explosion, thermal efficiency height, the scope of application are wide, thereby, have good value for applications.
4, description of drawings
Accompanying drawing 1 is the structural representation of bilateral circulating vacuum glass heat collection tube.
Among the figure: minor thread lid (1), little O type circle (2), adapter sleeve (3), major thread lid (4), big O type circle (5), outer glass pipe (6), inner glass tube (7), vacuum layer (8).
5, the specific embodiment
With reference to explaining below 1 pair of bilateral circulating vacuum glass heat collection tube work of the present utility model of Figure of description.
Bilateral circulating vacuum glass heat collection tube of the present utility model, structure comprises inner glass tube (7), outer glass pipe (6), adapter sleeve (3), minor thread lid (1) and major thread lid (4), interior, the left end of outer glass pipe is or/and right-hand member is connected with adapter sleeve (3), wherein at left end, minor thread lid (1) closely is connected the left end of adapter sleeve (3) by tightly being enclosed within little O type circle (2) on the inner glass tube (7), the left end of outer glass pipe (6) withstands on the boss place in the middle of the adapter sleeve (3), major thread lid (4) closely is connected the right-hand member of adapter sleeve (3) by tightly being enclosed within big O type circle (5) on the outer glass pipe (6), is vacuum layer (8) between inner glass tube (7) and the outer glass pipe (6).
Bilateral circulating vacuum glass heat collection tube of the present utility model also can be used on the single-pass vacuum glass heat collection tube, and promptly an end of single-pass vacuum glass heat collection tube is equipped with this adapter sleeve.
Claims (1)
1, bilateral circulating vacuum glass heat collection tube, it is characterized in that structure comprises inner glass tube, outer glass pipe, adapter sleeve, minor thread lid and major thread lid, at the left end of inside and outside glass tube or/and right-hand member is connected with adapter sleeve, wherein at left end, minor thread lid closely is connected the left end of adapter sleeve by tightly being enclosed within little O type circle on the inner glass tube, the left end of outer glass pipe withstands on the boss place in the middle of the adapter sleeve, major thread lid closely is connected the right-hand member of adapter sleeve by tightly being enclosed within big O type circle on the outer glass pipe, is vacuum layer between inner glass tube and the outer glass pipe.
