Description
Technical field
The present invention relates to environmental chamber sampling technique fields, more specifically to a kind of environmental chamber sampling apparatus.
Background technology
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 sizes of detection artificial board, furniture, auto parts and components etc. meet national standard.This method it is main excellent
Putting is：Measurement data can directly reflect material release formaldehyde and the present situation of VOC, and obtaining data and environmental pollution states has directly
Connect correspondence.It is the external method generally used such as European Union that use environment test chamber, which measures material formaldehyde VOC burst size methods,.
Under environmental chamber test environment, a ring, the sampling of traditional environmental chamber are very important to the sampling of gas in cabin
Mouthful, exactly opening up an osculum in environmental chamber nacelle, and a siphunculus is drawn by osculum, multiple air flues is opened up on pipe,
And multiple thief hatch are connected to being detected by gas by multiple air flues, there is difference in the gaseous environment that more X air flues are adopted
Different, error is larger.
Invention content
In view of the deficiencies of the prior art, the present invention intends to provide a kind of environmental chamber sampling apparatus.
To achieve the above object, the present invention adopts the following technical scheme that：A kind of environmental chamber sampling apparatus, including it is connected to cabin
Sampling air inlet on body and the sampling unit being connected on sampling air inlet, the sampling air inlet is equipped with air inlet sampling connection
Pipe, the air inlet sampling connecting tube are equipped with sampling pipe, and the sampling pipe is equipped with the outer silk Sampling Interfaces 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 air bleeding valve.
Preferably, the air bleeding valve is venting ball valve.
The present invention compares has the following advantages compared with the prior art：Silk Sampling Interface outside multiple VOC is connected by sampling pipe
It is connected on air inlet sampling connecting tube, and connecting tube is sampled by air inlet and is connected to indoor environment so that the outer silk Sampling Interfaces of multiple VOC
The air inlet environment of acquisition is consistent, and the numerical error that detected is greatly reduced compared to traditional technology.
