Abstract
Vacuum glass capable of being vacuumized repeatedly comprises upper and lower layer glass plates, middle supports, peripheral sealing bodies and a pumping hole. The vacuum glass is characterized in that a one-way pumping valve is installed in the pumping hole, and the pumping hole is formed in a piece of plate glass of the vacuum glass plates. When gases in the vacuum glass are required to be pumped, the pumping valve and a vacuum pump are connected through a pipeline, and the vacuum pump is started to pump the gases in the vacuum glass; and when a designed vacuum degree is realized inside the vacuum glass, the pumping valve is closed, and pumping is stopped.
Description
Technical field
The utility model relates to vacuum glass and manufactures field, especially a kind of vacuum glass that can repeatedly vacuumize.
Technical background
Vacuum glass is exactly staggered relatively two blocks of sheet glass, surrounding sealing, and extract the gas between vacuum glass out, and the method vacuumizing has two kinds, and one is to vacuumize with edge sealing once to complete, and this technique is generally to complete in vacuum furnace; Also having one is the sealing-in of two sheet glass surroundings, and then extracts the gas in the middle of sheet glass out from aspirating hole, after withdrawing gas, aspirating hole is sealed.If the vacuum glass gas leakage that above-mentioned two kinds of methods are produced, vacuum glass is also just scrapped and cannot be repaired.
Utility model content
The purpose of this utility model is, a kind of vacuum glass that can repeatedly bleed is provided, and after vacuum glass leaks gas, can carry out secondary pumping to vacuum glass easily.
The technical solution of the utility model is: a kind of vacuum glass that can repeatedly bleed, comprise levels sheet glass, intermediate supports, surrounding sealing member and aspirating hole, and it is characterized in that being provided with in aspirating hole unidirectional evacuating valve.When need in extracting vacuum glass gas time, evacuating valve is connected with vacuum pump pipeline, start vacuum pump, the gas in extracting vacuum glass, when reaching in vacuum glass after the vacuum tightness of design, closes evacuating valve, stops bleeding.
The above-mentioned vacuum glass that can repeatedly bleed, is characterized in that: it is on glass that aspirating hole is opened one flat plate in hollow plate glass.If aspirating hole is opened on side seal body, be inconvenient to install installing when vacuum glass, and need to again bleed time, because edge of vacuum glass is crushed on below plastic-steel window press strip, while bleeding, press strip to be taken down, also inconvenience.Attractive in appearance again in order not affect use, aspirating hole is preferably disposed on four jiaos, apart from Edge Distance 3-5cm place.
Usefulness of the present utility model is repeatedly repeatedly to bleed to vacuum glass, guarantees the heat insulation performance of vacuum glass.
Accompanying drawing explanation
Fig. 1---the vacuum glass schematic diagram that can repeatedly vacuumize.
1-upper strata glass, 2-lower floor glass, 3-upholder, 4-surrounding sealing member, 5-aspirating hole, 6-check valve, 7-seal gum, 8-valve cover.
Specific embodiments
As shown in Figure 1, this is structural representation of the present utility model:
Vacuum glass is by upper lower glass plate 1,2, upholder 3, surrounding sealing member 4, check valve 6 forms, and check valve is according in aspirating hole 5, and check valve 6 is bonded in upper glass plate 1 with seal gum 7, while bleeding, valve cover 8 is taken off, vacuum pump is connected on check valve 6 by pump-line, starts vacuum pump, extract the gas of vacuum glass out, in the time reaching design vacuum tightness, close vacuum pump, take off pump-line, then on valve cover.
When organic gel sealing glass, often gas leakage, but this venting process is very slow, and more than general 2-3.Organic gel is due to seal temperature low (general 150 ℃), while using like this toughened glass to do vacuum glass, can guarantee that toughened glass is unannealed, and sealing technology is simple, product intensity is high, and easy transportation and installation have advantages of very large, by the valve that can repeatedly bleed is installed on vacuum glass, can ensure the normal use of the vacuum glass of secret sealing.
Claims (2)
1. the vacuum glass that can repeatedly vacuumize, comprises levels sheet glass, intermediate supports, surrounding sealing member and aspirating hole, it is characterized in that being provided with in aspirating hole unidirectional evacuating valve.
2. the vacuum glass that can repeatedly vacuumize according to claim 1, is characterized in that aspirating hole is opened one flat plate in hollow plate glass on glass.
