Abstract
The utility model belongs to a kind of device applied to indoor assessment drier air-tightness, is specifically changed with time with stability gas nitrous oxide solubility as index, assesses the air-tightness of drier.The device is a Clear glass bottles and jars, is mainly made of six part such as body, bottle cap, stopper, rubber pad, sampling probe, sample tap.Wherein the joint of body and bottle cap is coated with one layer of vaseline, to guarantee that it is seamless that body and bottle cap combine.Bottle cap and stopper are main parts, at the screw top mouth of bottle cap with can rotating stopper can cover on bottle cap, guarantee to provide a closed air-locked environment.Sampling probe protrudes into bottle and on stopper, and wherein sample tap is mounted with a valve, for syringe sampling, to reduce gaseous sample in the loss of sample tap part.It is the key device of a closed air-locked structure that the effect of rubber pad, which is inside guarantee device,.
Description
Technical field
The utility model belongs to a kind of device applied to indoor assessment drier air-tightness, is a kind of quick, safety, height
Effect, device that is accurate, reliably can apply to indoor detection drier air-tightness.
Background technique
Drier is usually used in interior and does stifling experiment, and air-tightness is to guarantee the important prerequisite of fumigating effect.But at present still
Have no the device of reliable testing and evaluation drier air-tightness.Developing quick, safe and efficient, reliable detection method is to comment
Estimate the important process of drier air-tightness, and carries out the primary guarantee of indoor stifling experiment.
Utility model content
Critical issue to be solved in the utility model is: the air-tightness of drier is assessed, with stability gas nitrous oxide
Solubility changes with time as index.Ensure the airtightness of device and the simplicity of sampling and high efficiency, it is characterized in that (1) is dry
Dry device body and bottle cap are evenly coated with vaseline, and body can be made, which to combine closely with bottle cap, prevents gas from leaking;(2) sample tap includes
One Simple valve, there is a rotatable stopper at the lid end screw top mouth of drier, stopper top and the bottom with it is each at sampling probe
There is a rubber pad, enhances air-tightness;
The technical solution of the utility model is: a kind of device applied to indoor assessment drier.
The device is clear glass cylinder shape bottle, mainly there is body, bottle cap, rubber pad, sampling probe, sample tap, stopper etc.
Six parts composition.Wherein body and bottle cap are main parts, and the top tool screw thread of bottle cap guarantees on bottle cap so that stopper can be covered
One closed air-locked environment is provided.Sampling probe passes through stopper, protrudes into inside bottle body, and wherein stopper upper and lower surface respectively installs one
A rubber pad, sampling probe other end connects Simple valve, for syringe sampling, to reduce gaseous sample in the stream of sample tap part
It loses.The effect of rubber pad is to guarantee that device is the key device of a closed air-locked structure.The assembly dia: 20 ㎝ high:
18 ㎝, sampling probe protrude at the 1/2 of bottle height.Body and bottle cap are sealed with vaseline when test, stopper is tightened, from sampling
Mouthful a certain amount of nitrous oxide calibrating gas is injected, from being then shut off valve.
A kind of device applied to indoor detection drier air-tightness, it is characterised in that: body and bottle cap vaseline are equal
Even smearing, slowly screws bottle cap toward the clockwise direction, and body and bottle cap can be allowed to combine closely, guarantee inside device one it is closed
Environment can greatly reduce gas scattering and disappearing in seam crossing.
A kind of device applied to indoor detection drier air-tightness, it is characterised in that: sample tap be mounted with one it is simple
Safety-valve, can be closed rapidly to take sample, can greatly reduce gaseous sample at sample tap scatter and disappear.
A kind of device applied to indoor detection drier air-tightness, it is characterised in that: with stability gas nitrous oxide
Solubility changes with time as index, assesses the air-tightness of drier.When test, a certain amount of nitrous oxide is injected from sample tap
Calibrating gas measures the variation of drier internal oxidition Asia nitrogen solubility in different time points.
Utility model has the advantages that in room conditions can simply, safely, efficiently, fastly assess drier
Air-tightness.
Detailed description of the invention
Fig. 1 is the planar configuration schematic diagram of the utility model.
1, body 2, sampling probe 3, stopper 4, Simple valve
5, sample tap 6, rubber washer 7, bottle cap 8, vaseline coating
Specific embodiment
Below in conjunction with attached drawing and specific embodiment, the utility model is described in further detail.Following embodiment is only
It is only the description that preferred embodiments of the present invention are carried out, is not to be carried out to the conception and scope of the utility model
It limits, under the premise of no disengaging the utility model design conception, those skilled in the art are to the utility model skill
The various transformations and improvement that art scheme is made, should all fall into the protection scope of the utility model, the utility model is claimed
Technology contents are all described in the claims.
Examples of implementation:
We have done the assessment measurement of drier air-tightness in room conditions:
Device inside and outer wall are cleaned up completely first when experiment, are fixed on sample tap valve (4) with from sealer
On sampling probe (2), sampling probe passes through stopper (3) and protrudes into bottle body (1), and stopper (3) top and the bottom are respectively installed with sampling probe (2) contact position
One rubber pad (6) is aligned stopper (3) with bottleneck and tightens, and closes valve (4).It is uniform at the edge of body (1) and bottle cap (7)
One layer of vaseline is coated, screws bottle cap toward the clockwise direction after closing bottle cap, until body and bottle cap are completely combined.Then will
The nitrous oxide calibrating gas that 200ml solubility is 100ppm injects in bottle from sample tap, valve of closing the door rapidly.Three weights are set
It is multiple.Gaseous sample 10ml injection 20ml headspace sampling bottle is extracted from sample tap with air-tightness needle for the first time after 2 hours, using conjunction
Suitable condition utilizes GC-MS test sample.Hereafter it every other day extracts gaseous sample and detects its solubility, the test period is 20 days.
Data analysis statistical is carried out with " SPSS data processing system ", with the percentage of nitrous oxide solubility (mg/kg) (with first time sample
Product concentration is reference, percentage=sample solubility of each time point/first time sample solubility) it is ordinate, it is cross with sample time
Coordinate establishes gas solubility-time changing curve in drier.
In 15 days device for dring inner part nitrous oxide concentration fluctuation less, nitrous oxide high percentage in 93% (93% ±
3.3%), start to be reduced to 86% within the 16th day.Show that 15 days device for dring inner part show good air-tightness.The utility model structure
Simply, manufacturing cost is low, and corrosion resistance is strong, operation visualization, it can be estimated that the air-tightness of drier.
The technical means disclosed in the embodiments of the present invention is not limited to the technical means disclosed in the above technical means, and further includes
The technical solution as composed by the above technical characteristic equivalent replacement.Unaccomplished matter of the invention, belongs to those skilled in the art's
Common knowledge.
