Description
Technical field
The utility model relates to a kind of glass, especially a kind of vacuum glass.
Background technology
The effect that glass plays in the middle of people live is more and more wider, single use under construction, and it is material that a lot of daily necessitiess also adopt glass.Glass commonly used is transparence, can keep daylighting effect preferably, particularly in buildings, generally adopt the double glazing of in door and window, packing into to avoid room temp to be subjected to the influence of external environment in order to be incubated with daylighting, though this method can tissue compartment outer cold-hot air convection but thermal conduction that can not isolation glass self, therefore the effect of its heat-insulation and heat-preservation is not very desirable, and the shared area of the glass on the building is increasing, calorific loss is also bigger, especially when the temperature difference of glass both sides is very big, the energy that consumes is also bigger, for remedying the loss of energy, the energy that just must consume other replenishes, and obviously like this can cause energy dissipation, simultaneously also can cause serious pollution, and its soundproof effect is relatively poor to ecotope.
The appearance of vacuum glass preferably resolves the problems referred to above.At first, vacuum glass has good heat preservation and insulation, uses it as window-glass, the winter room is heated up rapidly, and room heater is difficult for scattering and disappearing, and summer is during indoor use air-conditioning, indoor cold air is difficult for excessive, has reduced the cost of use of heating and air-conditioning, save energy; Secondly, vacuum glass has sound-proofing properties preferably as exterior wall glass, prevents the interference of ambient noise, has realized indoor quiet environment.
At present, the production method of vacuum glass mainly contains two kinds, and a kind of is to preset aspirating hole on the sheet glass plane, and aspirating hole seals aspirating hole, and this method can stay obvious marks on the vacuum glass finished product, had a strong impact on the attractive in appearance and safety of hollow plate glass; Another kind method is to bleed to melt the hollow plate glass of envelope in vacuum chamber, this method can not stay the bleeding point vestige on hollow plate glass, but the time of melting the limit in vacuum chamber is longer, and it is higher to melt the limit cost, yield rate is relatively low, has improved the manufacturing cost of vacuum glass.
The patent No. is 200820163882.3, the name be called " vacuum glass " patent disclosure a kind of vacuum glass, this vacuum glass comprises two isolating glass at least, seal gum between glass and the glass adopts epoxy resin glue, seal gum is along glass periphery sealing one circle, and on seal gum, be provided with aspirating hole, will vacuumize between two glass by aspirating hole.The defective that this vacuum glass exists is: at first, the diameter of aspirating hole is 0.1mm, and its diameter is less, so the pumpdown time is long; Secondly, bleed after the end, also need aspirating hole is sealed, so its operation more complicated; In addition, be coated with in the seal gum process, the height of epoxy resin glue is wayward, and the glue-line height is inhomogeneous, is easy to cause gas leakage, causes vacuumizing inefficacy, and yield rate is low.
The utility model content
The purpose of this utility model is to have proposed a kind of vacuum glass, and this vacuum glass surfacing keeps vacuum tightness effectively, long service life, and production cost is low.
The utility model is to adopt following technical scheme to realize: a kind of vacuum glass, comprise upper glass plates and lower glass plate, the downside of upper glass plates is relative with the upper side of lower glass plate, be provided with point of suppon between upper glass plates and the lower glass plate, it between upper glass plates and the lower glass plate vacuum chamber, the two ends up and down of point of suppon contact with lower glass plate with upper glass plates respectively, wherein, on described, between the lower glass plate and be provided with the ring sealing part of a sealing at least along the edge, four limits of upper glass plates downside and lower glass plate upper side, sealing element is provided with from outside to inside at interval along the edge, four limits of sheet glass.
In the utility model, the outside surface of described sealing element can be coated with paillon foil, also can be covered with paillon foil at the annular outboard face and/or the annular inboard bread of sealing element.
The equal machined grooves of the downside of described upper glass and edge, the upper side of lower glass plate four limit, the shape of groove is corresponding with the shape of sealing element, and sealing element is arranged in the groove, and the degree of depth of groove is 0.1-1mm.
Between the described upper and lower sheet glass and be provided with the ring sealing part of a sealing at least along the edge, four limits of upper glass plates downside and lower glass plate upper side, sealing element is provided with from outside to inside at interval along the edge, four limits of sheet glass.
Described sealing element can be sealing-ring, also can be made up of the sealing-ring and the bar that is tightly connected, and fixedlying connected with the two sides of the bar that is tightly connected in the two ends of sealing-ring, and forms the ring body of sealing.
Be inserted with apparatus for vacuum producing in the described bar that is tightly connected, the diameter of apparatus for vacuum producing is 0.5-1.0mm.
One end of described apparatus for vacuum producing is communicated with cavity between the upper and lower sheet glass, and the other end is connected with vacuum pump.Described apparatus for vacuum producing also can be three-limb tube, and the one end inserts in the bar that is tightly connected, and is communicated with cavity between the upper and lower sheet glass, and second end is connected with vacuum pump, and the 3rd end is connected with the container that inorganic seal gum is housed is airtight.
When this vacuum glass is produced, make sealing element crimp by pushing upper and lower sheet glass, the recoverable deformation of sealing element makes between the upper and lower sheet glass and forms annular seal space, annular seal space is vacuumized make this cavity become vacuum chamber.Usually under the state, have a lot of minute apertures in the elastic sealing element, this moment, sealing element easily produced micro-leakage under certain pressure reduction, can't make the permanently effective maintenance vacuum of cavity between two sheet glass; But under bigger squeeze effect, minute aperture in the sealing element is squeezed into wire, a large amount of minute apertures is sealed, the gas molecule is difficult to infiltrate, therefore can play the better seal effect, the airproof paillon foil that the sealing element outside surface coats can remedy the seepage and the gas release performance of sealing element, thereby keeps the vacuum tightness in the vacuum chamber.
The beneficial effects of the utility model are: compare with existing vacuum glass, at first, this vacuum glass surfacing, good looking appearance; Secondly, its good airproof performance, the yield rate height guarantees vacuum tightness effectively, good airproof performance, long service life, and played the effect of heat-insulation and heat-preservation and noise isolation.
