The communicating pipe 5 and the sealing cover 8 are fixed and sealed by a sealant 9; the sealant 9 can be structural adhesive or other materials with fixing and sealing functions. The length of the communicating pipe 5 extending into the rigid air port 7 is less than the length of the rigid air port 7, so that the communicating pipe 5 is prevented from puncturing the flexible air bag 6 or the flexible air bag 6 blocks the communicating pipe 5. In other embodiments of the present application, the flexible air bag may also be an aluminum plastic bag, an aluminum foil bag, a plastic bag, a rubber bag or a silicone bag.

Example 3
The present embodiment provides a pressure-adjustable hollow glass, the main structure of which is the same as that of embodiment 1, and the details of the same parts are not repeated. The present embodiment is different from embodiment 1 in that:
referring to fig. 6 and 7, in the present embodiment, the hollow glass includes 3 glass plates 1, which sandwich two hollow cavities 2, a circle of supporting frame 3 is disposed around each hollow cavity 2, and an airtight structural adhesive layer 4 is disposed outside the supporting frame 3.
In this embodiment, the communicating pipe 5 is made of an aluminum alloy pipe having a diameter of 0.5 mm.
In the present embodiment, two flexible airbags 6 are provided, and the two hollow cavities 2 are connected to one flexible airbag 6 through one communicating tube 5. The two flexible air bags 6 can be arranged on the same side of the hollow glass or on two sides of the hollow glass respectively.
In the above embodiments, the volume V of the flexible airbag 6Bag (CN)The design (i.e., the volume of gas that can be contained after the flexible airbag is fully inflated) needs to be divided into the following two cases:
(1) v if the flexible airbag needs to be used for a long time after the hollow glass is installedBag (CN)The following conditions need to be satisfied:
wherein, VBag (CN)Indicating the volume of the flexible air pocket, VChamberIndicating the volume of the hollow cavity, T0Denotes the production temperature, P, of the hollow glass0Indicating the air pressure of the hollow glass production; t is2maxRepresents the highest temperature of the hollow glass in use; t is2minRepresents the lowest temperature of the hollow glass; p2The atmospheric pressure used for the hollow glass is shown.
For example, the production place is Tianjin, the altitude of the production place is 35m, and the standard atmospheric pressure is 101300 Pa; the production temperature is as follows: 10 ℃, namely 283K; the use site is as follows: in Lanzhou, the altitude of the land is 1635m, the air pressure is 85300Pa, the highest temperature of the land is 30 ℃ or 303K, and the lowest air temperature is-10 ℃ or 263K.
VBag (CN)≥2*｜（303*101300）/（283*85300）-1｜* VChamber=0.54VChamber
VBag (CN)≥2*｜（283*85300）/（263*101300）-1｜* VChamber=0.19VChamber
For 1m by 2m hollow glass, the thickness of the cavity is 12mm, VChamber= 24L, the flexible airbag volume VBag (CN)≥0.54*24=12.96L，VBag (CN)≧ 0.19 × 24=4.56L, the larger of the two, namely VBag (CN)≥12.96L。
(2) If the flexible air bag is taken off after the hollow glass is installed and only the air pressure adjustment during transportation is considered, VBag (CN)The following conditions need to be satisfied:
wherein, VBag (CN)Indicating the volume of the flexible air pocket, VChamberIndicating the volume of the hollow cavity, T0Denotes the production temperature, P, of the hollow glass0Indicating the air pressure of the hollow glass production; t is1Indicating the temperature of the hollow glass in the transportation process; p1The air pressure during transportation of the hollow glass is shown.
Theoretically, the condition in the case (2) is also satisfied in the case (1) described above. However, in general, due to small temperature difference change in the transportation process, if only the air pressure adjustment in the transportation process is considered, the calculation result of the volume of the flexible air bag is smaller than that calculated according to long-term use; therefore, according to the result of calculation of long-term use, the pressure regulation requirement in the transportation process can be met.
Furthermore, it is noted herein that the maximum volume of the flexible airbag generally need not be limited; however, in the actual production process, the length and width of the flexible air bag when it is empty will be generally smaller than the length and width of the glass plate so as not to affect the glass packing. Additionally, the volume of gas within the flexible air bag does not exceed the volume 2/3 at most.
It will be appreciated by those skilled in the art that the hollow cavity volume in the above equation for the flexible airbag volume calculation refers to the volume of the hollow cavity connected to the flexible airbag, and for a flexible airbag of the type described in example 2 connecting two hollow cavities, the hollow cavity volume V in the equationChamberI.e. the sum of the respective volumes of the two hollow cavities.
The application utilizes the principle of a communicating vessel to communicate the rigid hollow cavity with the flexible air bag through the communicating pipe; when the external air pressure of the glass changes due to the change of the altitude or the temperature, the flexible air bag deforms, the air pressure in the hollow cavity is adjusted, the air pressure in the hollow cavity is balanced with the external air pressure, the glass plate of the hollow glass is prevented from deforming, and the quality of the hollow glass product is ensured. This application is adjusting cavity glass atmospheric pressure in-process, and external aqueous vapor does not get into well cavity, and the intracavity argon gas of cavity is not revealed, ensures the U value. Especially to long, the time of transporting, humidity is big, when cavity intracavity gas is the gas (such as argon gas etc.) except air, the effect of this application is more obvious.
The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept.
