Description
Technical field
The utility model relates to environmental chamber sampling technique fields, more specifically to a kind of environmental chamber sampling apparatus.
Background technique
Environmental test chamber is actually a kind of test equipment of feasible simulation indoor environmental condition, in the cabin service condition
Under, the formaldehyde and VOC burst size of detection artificial board, furniture, auto parts and components etc. meet national standard.This method it is main excellent
Point is: measurement data can directly reflect material release formaldehyde and the status of VOC, and obtaining data and environmental pollution states has directly
Connect corresponding relationship.Use environment test chamber measurement material formaldehyde VOC burst size method is the external method generallyd use such as European Union.
Environmental chamber is tested under environment, is very important a ring, the sampling of traditional environmental chamber to the sampling of gas in cabin
Mouthful, exactly opening up an osculum in environmental chamber cabin, and a siphunculus is drawn by osculum, multiple air flues is opened up on pipe,
And connect multiple thief hatch by multiple air flues and detected to by gas, there is difference in the gaseous environment that more X air flues are adopted
Different, error is larger.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of environmental chamber sampling apparatuses.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of environmental chamber sampling apparatus, including connection
Sampling air inlet in cabin and the sampling unit being connected on sampling air inlet, the sampling air inlet is equipped with air inlet sampling
Connecting tube, the air inlet sampling connecting tube are equipped with sampling pipe, and the sampling pipe is equipped with the outer silk Sampling Interface of multiple VOC.
Preferably, being arranged with lagging casing on the sampling pipe, it is equipped with and protects between the sampling pipe and lagging casing
Warm layer, the insulating layer are filled with thermal insulation material.
Preferably, the sampling pipe top, which is equipped with, samples outer warehouse lid.
Preferably, the sampling pipe top is equipped with exhaust valve.
Preferably, the exhaust valve is venting ball valve.
The utility model is compared compared with the prior art to be had the advantage that silk Sampling Interface outside multiple VOC passing through sampling
Pipe is connected to air inlet sampling connecting tube, and samples connecting tube by air inlet and be connected to indoor environment, so that the outer silk sampling of multiple VOC
The air inlet environment that interface obtains is consistent, and the numerical error that detected is greatly reduced compared to traditional technology.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model environmental chamber sampling apparatus embodiment 1；
Fig. 2 is the structural schematic diagram of the utility model environmental chamber sampling apparatus embodiment 2.
In figure, 1- samples the outer silk Sampling Interface 5- heat preservation of air inlet 2- air inlet sampling connecting tube 3- sampling pipe 4-VOC

3, sampling pipe 3 is equipped with the outer silk Sampling Interface 4 of multiple VOC, and lagging casing 5 is arranged on sampling pipe 3, and sampling pipe 3 and heat preservation are outer
Insulating layer 6 is equipped between shell 5, insulating layer is filled with thermal insulation material, and 3 top of sampling pipe is equipped with venting ball valve (not shown),
It is installed on the pipeline of discharge directions.
In the present embodiment, silk Sampling Interface outside multiple VOC is connected to air inlet by sampling pipe and samples connecting tube, and is passed through
Air inlet sampling connecting tube is connected to indoor environment, so that the air inlet environment that the outer silk Sampling Interface of multiple VOC obtains is consistent, detects
The numerical error come is greatly reduced compared to traditional technology.
In the present embodiment, sampling apparatus and venting ball valve are combined, so that each sensor can in sample detecting
To obtain circulated gases, the possible environmental error of not circulated gases is avoided.
Environmental chamber sampling apparatus in the present embodiment is primarily adapted for use in the measurement of atm number.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model, should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
