Description
Technical field
This utility model belongs to Pilot Unit, is specifically related to a kind of environmental test chamber.
Background technology
Calibrating gas environmental test chamber is environmental cabinet (the hereinafter referred to as environmental test that can control to export certain concentration gas
Case), for some, it can require that the experiment with certain background concn provides suitable experimental situation.
Artificial producing has certain density gaseous environment, scientific research, produce, the field such as detection has and widely should
With.In existing environmental test chamber preparation process, the gas concentration in environmental test chamber is needed can quickly to reach experiment
The ambient concentration required, thus part wastes too many calibrating gas and time in the metamorphosis stage of environmental test chamber.Ring to be made
Gas in the proof box of border reaches to test required stable concentration, and traditional method is to use calibrating gas and pure air pre-
First make the gas (abbreviation object gas) of desired concn, then respectively connect a pipeline at the two ends of environmental test chamber, one
As admission line, one as outlet pipe.Object gas is constantly filled with in environmental test chamber by admission line, case
Interior gas is discharged outside environmental test chamber by outlet pipe, by original sky in the method removal environmental test chamber of displacement
Gas, general this replacement process requires that the gas volume being filled with is greater than more than 7 times of the internal volume of environmental test chamber.If
The object gas being filled with in case is gas costly, and the operating cost of the environmental test chamber of this substitute mode is the highest
Hold high.
Meanwhile, the encapsulant improper use of casing also can affect composition and the concentration of gas in environmental test chamber, tradition
Encapsulating method for processing cost and the consideration of actual environment, be usually use medical grade silicon rubber as sealing ring.But silicon
The pollutant discharging comparison of ingredients complexity of rubber meeting trace itself, including formaldehyde, benzene and various VOC (volatile organic
Compound) gas.If experiment itself is higher to the concentration requirement of gas in case, or require the comparison of ingredients list of gas in case
In the case of one, experiment then can be exerted an adverse impact by silicone rubber O-ring.
Therefore, complete ventilation the most quickly, frugally to environmental test chamber, avoid the material of manufacturing environment proof box simultaneously
Case internal object gas is polluted, is current those skilled in the art's problem demanding prompt solution.
Summary of the invention
This utility model aims to overcome that the deficiencies in the prior art, it is provided that a kind of environmental test chamber.
Above-mentioned purpose is achieved by the following technical solution:
A kind of environmental test chamber, including casing, sampling bottle and three breathers connecting casing and sampling bottle；Casing is provided with
Escape pipe inside and outside connection casing, is provided with displacement air bag in casing, displacement air bag is connected with outside casing by displacement trachea, displacement
Trachea is provided with the first valve, and escape pipe is provided with the second valve；The two ends of described three breathers respectively with casing and sampling bottle
Connection, the one end connected with casing is provided with the 3rd valve, and the one end connected with sampling bottle is provided with the 4th valve, and residue one end is inspection
Surveying end, test side is provided with the 5th valve；Sampling bottle, in addition to connecting with three breathers, is also communicated with sampling air inlet pipe.
Further, described casing is provided with observation window.
Further, described casing is provided with operation window.
Further, described casing is provided with a spike.
Operation principle:
Before filling object gas in casing, first passing through displacement trachea will after displacement airbag aeration, displacement airbag inflation
In casing, original air is discharged by escape pipe, and now, the first valve, the second valve are opened, the 3rd valve closing.In casing
When filling object gas, the sampled air inlet pipe of object gas enters sampling bottle, then in three breathers enter casing, now, the
Four valves, the 3rd valve, the first valve are opened, the second valve, the 5th valve closing.Need the gas in casing is detected
Time, then after displacement airbag aeration, displacement airbag inflation, the target gas in casing is passed through three breathers by displacement trachea
Test side discharge detect, now, the first valve is opened, the second valve closing, and the 3rd valve is opened, and the 5th valve is beaten
Open, the 4th valve closing.
The beneficial effects of the utility model:
The environmental test chamber that this utility model provides can effectively replace the original gas in casing, effectively saves and is used for filling
The amount of the object gas in cartonning body, object gas expensive for research, that be not easy to obtain is significant.
