Abstract
The utility model relates to a sealing joint, which is used for the connection of a solar vacuum tube and an inner housing body in the equipment utilizing the solar vacuum tube to heat liquid or gas. The utility model comprises sealing rings, nuts, and connecting sleeves. The utility model is characterized in that one end of the tubular connecting inner sleeve is connected with the end face compression nut via the tubular connecting outer sleeve, and the other end of the tubular connecting inner sleeve is connected with the nut; the two end faces of the tubular connecting outer sleeve are respectively provided with a sealing ring, and a sealing pad is arranged between the end faces of the tubular connecting outer sleeve and the outer step surface of the end face compression nut. The utility model has the advantages that the sealing is reliable, the installation is convenient, and the heat efficiency of the solar vacuum tube can be improved by about 10%.
Description
The utility model relates to a kind of SEALING FITTING of utilizing solar energy vacuum tube in solar energy vacuum tube heating liquid or the gas apparatus to be connected usefulness with inner housing.
At present, the utilization of solar energy more and more is subjected to various countries and payes attention to widely, and it is a kind of free of contamination natural energy resources; And the exploitation of glass vacuum heat collection tube of solar energy has been opened up a boundless development prospect to better utilization solar energy; Glass vacuum heat collection tube of solar energy can absorb solar energy effectively, and be translated into heat energy, be used to produce the heat supply of domestic hot-water and industrial aspect, but in use, heat collecting pipe is not very good with being connected of inner housing, present SEALING FITTING all adopts the elasticity that relies on seal ring self to seal water or gas, when hydraulic pressure increases or air pressure when increasing, and the problem of leaking, leaking gas with regard to generation.Though the utility model patent of the existing this respect of the inventor in use, feels also very dissatisfied.
It is a kind of easy to use that the purpose of this utility model is to provide, and good sealing effect, can effectively utilize a kind of solar energy evacuated SEALING FITTING of effective daylighting area of glass vacuum heat collection tube of solar energy.
The technical solution of the utility model is: a kind of solar energy vacuum tube SEALING FITTING, comprise seal ring, nut, connecting sleeve, it is characterized in that being with externally threaded tubulose to connect interior cover (8) one ends is connected it by tapped tubulose connection overcoat (6) with end face gland nut (1), the other end of cover (8) linked to each other with nut (10) in tubulose connected, and the both ends of the surface of cover (8) are separately installed with seal ring (7), (11) in tubulose connects; Between the cylindrical step surface of the end face of tubulose connection overcoat (6) and the existing gland nut (1) of end sealing gasket (3) is installed.Monolateral being shaped as in end face gland nut (1) cross section-T type, the end face of solar energy vacuum tube (9) withstand on the step end face of end face seal nut (1) endoporus, and sealing gasket (2) also can be installed between its both ends of the surface.Have one the seal groove of seal ring (11) usefulness is installed in the one end endoporus of nut (10).
The utlity model has the manufacturing process that sealing is reliable, easy for installation, simplified connected bucket, and because the pipe on the bucket seal ring in will being installed in originally, in bucket, moved between the inside and outside bucket, effective heated length of vacuum tube is fully utilized on the basis that does not change original pipe range, has improved the thermal efficiency nearly about 10% of solar energy vacuum tube.
Embodiment of the present utility model is explanation in detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is a structural representation of the present utility model.
The end face seal pad 2 of solar energy vacuum tube 9 withstands on the step surface of end face gland nut 1 endoporus as shown in Figure 1, end face gland nut 1 be with externally threaded tubulose be connected in cover 8 connect overcoat 6 by tubulose and interconnect, in tubulose connects, overlap between 8 both ends of the surface relative seal ring 7 is installed with end face gland nut 1, in connecting, tubulose between the step surface of the other end of cover 8 and nut 10 endoporus seal ring 11 is installed, when swivel nut 10 and end face gland nut 1, by overlapping 8 in connecting with two seal rings 7,11 compress, it tightly is enclosed within on the solar energy vacuum tube 9, thereby has reached sealing effect; In bucket 4 by be installed on the end face gland nut 1 cylindrical step surface sealing gasket 3 be installed in the sealing gasket 5 that tubulose is connected overcoat 6 end faces itself and solar energy vacuum tube SEALING FITTING be tightly connected.
