Abstract

The utility model discloses a sealing structure of a solar water heat vacuum tube and an inner liner inserting hole, which comprises an inserting hole and a sealing ring, wherein the inserting hole is arranged on an inner liner. The edge of the inserting hole is flanged for two times. The flanging height is within 5.8mm to 6.0mm. The sealing ring is configured on the inserting hole. A notch adapted to the flanging height is arranged on the outer wall of the sealing ring. An O-ring is arranged on the inner wall of the sealing ring. The sealing ring is connected with the inserting hole through the notch. The utility model has the advantages that the sealing effect is good, the structure is simple, the installation is easy and convenient, and the quality and the service life of the solar water heater are greatly improved.

Description

The hermetically-sealed construction of solar water heater vacuum-tube and inner bag spliced eye
Technical field
The utility model relates to a kind of solar water heater, particularly the hermetically-sealed construction of solar water heater vacuum-tube and inner bag spliced eye.
Background technology
At present, the hermetically-sealed construction of solar water heater vacuum-tube of selling on the market and inner bag spliced eye has two kinds: a kind of is that the inner bag spliced eye is a flange, the sealing ring of outer wrapping spliced eye in configuration is gone up afterwards.This kind structural strength is relatively poor, scratches sealing ring simultaneously in the assembling process easily and causes seal failure.Another kind is the spliced eye secondary flange of deriving out on a flange basis, and the flange height is between 3.5mm-4.0mm, and the sealing ring of interior outer wrapping spliced eye is gone up in configuration afterwards.Though this kind structure has solved sealing ring to a certain extent and scratched situation about damaging, it is little to seal critical range, and the lubricating requirement height is installed, and often occurs seepage easily.Therefore be badly in need of wanting a kind of spliced eye hermetically-sealed construction of good sealing effect on the market.
The utility model content
The purpose of this utility model is to provide the hermetically-sealed construction of a kind of solar water heater vacuum-tube and inner bag spliced eye, and the sealing sealing structure is effective, installs easy and convenient.
The utility model for achieving the above object, the technical solution of employing is:
The hermetically-sealed construction of solar water heater vacuum-tube and inner bag spliced eye, comprise spliced eye and sealing ring on the inner bag, spliced eye is through twice flange, the flange height is between 5.8mm-6.0mm, dispose sealing ring on the spliced eye, the sealing ring outer wall has and the suitable notch of flange height, and inwall is provided with O type ring, and sealing ring is connected with spliced eye by notch.
The height of above-mentioned sealing ring is three times of spliced eye flange height, and the notch on the sealing ring is opened the centre position at its outer wall.
Above-mentioned sealing ring inwall is provided with three road O type rings.
Above-mentioned sealing ring is the sealing ring of being made by silica gel.
Turnover place of twice flange of above-mentioned spliced eye is an arc chord angle.
The beneficial effects of the utility model:
1, spliced eye flange height has increased the critical range that vacuum tube and inner bag are sealed and matched between 5.8mm-6.0mm, has promoted effective reliability of sealing.
2, turnover place of twice flange of spliced eye is an arc chord angle, has strengthened the rigidity of spliced eye, avoids spliced eye to be out of shape because of stressed effect.
3, spliced eye and silica gel sealing ring form close fit, similar one stifled anti-pierced wall has enlarged the critical range of fitted seal, have also avoided the potential problem of sealing ring scuffing, damage simultaneously.
In addition, that the sealing structure also has is simple in structure, easy and convenient advantage is installed, to the solar water heater quality and all have service life significantly and promote.
Description of drawings
Fig. 1 is the structural representation of inner bag spliced eye.
Fig. 2 is the schematic diagram of solar water heater vacuum-tube and inner bag spliced eye hermetically-sealed construction.
Below in conjunction with accompanying drawing the utility model is elaborated:
The specific embodiment
In conjunction with Fig. 1, Fig. 2, the hermetically-sealed construction of solar water heater vacuum-tube and inner bag spliced eye comprises spliced eye 1 on the inner bag and the sealing ring of being made by silica gel 2.Spliced eye 1 is through twice flange, and the flange height is 5.8mm or 6.0mm, configuration sealing ring 2 on the spliced eye 1, and sealing ring 2 outer walls have and the suitable notch of flange height, and inwall is provided with three road O type rings 3, and sealing ring 2 is connected with spliced eye 1 by notch.The height of sealing ring 2 is three times of spliced eye 1 flange height, and the notch on the sealing ring 2 is opened the centre position at its outer wall.Turnover place of spliced eye 1 twice flange is an arc chord angle.
In the installation process, sealing ring 2 is contained on the spliced eye 1, afterwards vacuum tube is inserted in the sealing ring 2, assembling is finished.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
