Description
Technical field
The utility model is related to double glazing preparation field, and in particular to a kind of double glazing constant pressure inflation system.
Background technology
With country about the policy of building energy conservation and the vigorously implementing of regulation, building energy conservation knowledge it is gradually general
And, people's double glazing demand high to energy-conservation configuration is also being continuously increased, and the large-scale production of low radiation coated glass is brought
The market growth relative raising, make it possible that the effective demand amount of high-performance hollow glass is continuously increased.Then occur
Increasingly it is widely applied in terms of preparing low-emissivity coated hollow glass, it is in the ascendant.But the application of low emissivity glass brings me
Before two problems never running into：(1) using offline low-emission coated making double glazing, the requirement to sealing life becomes
Obtain and more protrude；(2) after use low emissivity glass solves the problems, such as heat radiation, the thermal convection current in reduction double glazing cavity just becomes
Obtain very urgent.
Filling inert gas into hollow glass contributes to while improving sealing life and reduction thermal convection current, and inflate double glazing institute
Necessary initial inflation process concentration and air-tightness, are the basic guarantees for solving the problems, such as these two aspects, in general, inflate double glazing
Used inert gas be argon gas, with it is colourless, tasteless, nontoxic the characteristics of, its molecular weight weighs 38%, thermal conductivity factor compared with air
It is smaller than air.
Air that prior art is inflated in air of the technology in by double glazing reaches by way of being replaced as argon gas
The purpose of inflation, because the density ratio air of argon gas is big, therefore, when double glazing is inflated, it is necessary to set two holes, argon gas fills
(entering) stomata goes out (row) stomata in upper end in lower end, air, to displace the air in double glazing, reaches required argon
Gas concentration, this inflation, which is substantially, takes a breath and on-inflatable, and gas replenishment process is substantially that flowing gas is shifted from a kind of motion state
To the process of another state, whether high charge-air mass is produces laminar flow (laminar) with gas or is turbulent flow (turbul
Ence it is) relevant.
Inertia force and viscous force coefficient result when laminar flow and turbulent flow are motion of viscous.Motion of viscous with
The main distinction of perfect fluid motion be the stress of micelle in addition to inertia force, also viscous force.According to the characteristics of both power, it
Influence to fluid micellar motor behavior be different.According to definition, the effect of viscous force is to prevent fluid micellar from occurring phase
To moving, and the effect contrast of the effect of inertia force and viscous force, therefore in viscous fluid flow, the behavior of flowing is determined
The result acted on due to both power.Under action condition of the effect much larger than inertia force of viscous force, gas motion produces layer
Stream, conversely, when the effect of inertia force is much larger than the effect of viscous force, gas motion produces turbulent flow.
Intuitively, as a kind of most simple image of fluid motion, laminar flow can regard adjacent to each other as and have
The fluid layer of " determining material meaning ", or perhaps in the absence of " the fluid line element " of mutual vibration, the one kind for carrying out sliding motion is prolonged
Stretch.Briefly, laminar flow is exactly the laminar flow of fluid.Now, fluid bears newtonian viscous stress in motion, between solid
Revolting the mechanical mechanism for the motion that slips over one another does not have any essential difference.Turbulent flow basic characteristics be have whirlpool property, scrambling, with
Machine, diffusivity and dissipativeness, be it is a kind of by differing in size, the spiral structure that frequency is different constitute, make its physical quantity to the time
Change with space shows irregular randomness.
When inflating double glazing generation turbulent flow, the argon gas that the partial air in double glazing cavity can not be charged all the time is put
Change, accordingly, there exist the requirement that the initial concentration of the inflation double glazing of turbulent flow is extremely difficult to prescribed by standard.In addition, inflation
During produced by turbulent flow, air is still in the middle position of double glazing cavity.When double glazing turbulent flow occurs now
As when, be vented the concentration detected by hole sensor in double glazing, in general, should be higher than that the central turbulent flow of double glazing cavity
Air, and the complete diffusion of the inert gas of double glazing need 6~8 hours.If carrying out on-line checking using this method,
Then measured concentration is apparently higher than the actual concentrations after diffusion.Therefore, we can not be using this detection method as in inflation
The on-line checking means of empty glass.Otherwise, occur in inflation double glazing under the conditions of turbulent flow phenomenon, testing staff can be provided wrong
Judgement by mistake.Such as there is the inflation double glazing of turbulent flow, the position for detecting double glazing using electrion process should be leaned on as far as possible
Closely spaced bar position.Three measurement points advised according to producer, just avoid the turbulent gas of inflation double glazing, i.e. air
Position, given concentration is the concentration of inert gas.Therefore, it is necessary to after inflation double glazing is placed 6~8 hours, obtain
Go out correct concentration numeral.According to investigations, the inflation double glazing initial concentration of some producer's self-inspections is more than 90%, but through the 3rd
Side's measurement actual concentrations are significantly lower than 90%, even less than 70% had.By close to the big inflatable glass of these concentration difference
The outward appearance detection of envelope, we are difficult to find out any seal defect, therefore, it is concluded that one of the reason for this phenomenon occur, is
Caused due to turbulent flow.
But, this detection method belongs to the detection afterwards of product quality.After inflating double glazing placement 6-8 hours, the
Two road fluid sealants solidify substantially, if the concentration of inflation double glazing does not reach requirement, to returning for the double glazing inflated
Work is a thing wasted time and energy.In addition with two kinds of possibility：(1) if not improving inflation method, we still without
Method ensures that the carbonate concentration for the product done over again reaches requirement；(2) common inflation method is used, i.e., inflates and inflates naturally and be strong
Degassing method processed, unavoidably occurs turbulent flow phenomenon, even the glass of random inspection detection reaches concentration requirement, unless we have
Real-time monitoring numeral of the gas replenishment process per sheet glass, otherwise, we also can not definitely ensure the inflatable glass of whole batch
It is qualified.
As can be seen here, unless the charger that we use can be effectively prevented from turbulent flow and occur or remain to fill
The laminar flow of the stabilization of gas process, otherwise, we cannot exclude the true and false of the concentration of on-line checking.Furtherly, in this condition
Under, we ensure that the correct method of the concentration of inflation double glazing, can only be that the production process for inflating double glazing is controlled
System, rather than product quality control.
At present, the charge-air mass of China's double glazing is not high, is largely produced in gas replenishment process disorderly
Caused by stream.It is assumed that the sensor of charger only recognizes the concentration for the inert gas being collected at double glazing steam vent,
And the laminar flow and the inert gas concentration that finally provides of turbulent flow of inflation double glazing also correspond to standard requirement, people are with the naked eye again
It cannot be distinguished from the concentration trend of the inert gas of any piece double glazing after the diffusion.If using electrion process to this kind of inflation
The initial concentration of double glazing carries out on-line checking, and the concentration drawn will be higher by the actual concentrations after diffusion.As a result have two
Kind：If 1) product that producer there will be turbulent flow is judged as client good for delivery or is sent to test in laboratory, the reality after diffusion
Concentration will be lower than starting the concentration of test.2) the inflation double glazing of this concentration significant change can puzzle manufacturer, because
Sealing and zero defect for product, and the simply initial concentration of product test.
