(2) in sampler bag, the clean gas no less than 1000L it is filled with；
(3) heating sampler bag, to accelerate the rate of release of volatile organic matter；
(4) after some period of time, the gas in gas bleeding sampler bag, and test VOC content therein.
In experimentation, for ensureing the accurate of result, before carrying out (3rd) step, need to repeat aerofluxus and the inflation of more than four times, and during last inflation, need accurate meter gaseous volume.For ensureing air-tightness, sampler bag typically uses the teflon valve that bore is less.This causes above-mentioned technique to have the disadvantages that
(1) inflation and the aerofluxus different pipeline of use, causes needing in aerofluxus to be replaced as frequently as pipeline filling repeatedly, not only expends a large amount of manpower, and efficiency is low；
(2) during frequently changing pipeline, needing often to operate valve, cause valve easy to wear, its sealing and reliability reduce；
(3) gas flow of Artificial Control gas replenishment process, causes there is bigger error, affects experimental result.
Utility model content
The purpose of this utility model is to provide a kind of gas automatically to fill arranging device, and it uses same set of pipeline to be inflated and aerofluxus, saves the manpower changing pipeline, improves work efficiency, and not easily leads to the abrasion of valve.
A kind of gas fills arranging device automatically, it is characterized in that: include into trachea, escape pipe and the tubing connecting into trachea and escape pipe, described tubing includes two arms in parallel, article one, described arm is provided with flow controller, another described arm is provided with shut-off valve system, and the pipeline directly connected with the two ends of described shut-off valve system is provided with electromagnetic valve；Described entering also is provided with electromagnetic valve on trachea and escape pipe；Described electromagnetic valve is all connected with control panel with flow controller.
Gas of the present utility model automatically fills the trachea that enters of arranging device and is connected with gas cylinder, and stop valve is connected with sampler bag.When inflation, first pass around flow controller from the gas entering trachea, then enter sampler bag by stop valve；When aerofluxus, the gas from sampler bag enters pipeline by stop valve, and through flow controller, by gas outlet separating device.Controlled the folding of electromagnetic valve by control panel, the opening and closing of pipeline can be controlled, thus control the trend of gas, it is achieved inflation, the switching of exhaust flow path.Control panel can also control the gas flow through flow controller and flow velocity simultaneously so that it is keeps constant, to ensure the accurate of experimental result, improves efficiency and the safety of test.In one preferred embodiment, described control panel has display screen, and it can show the flow velocity and data on flows that flow controller detects in real time, it is simple to staff is adjusted according to experiment needs.
This utility model can also make following improvement: described gas outlet is connected with centrifugal blower or dry pump, and described centrifugal blower or the relay switch of dry pump are connected with described control panel.
Control panel sends signal, controls relay switch, and then controls gas outlet centrifugal blower or the opening and closing of dry pump.Automatically filling arranging device at gas to break down, do not operate for a long time or during off-test, relay switch can be automatically switched off, and cuts off centrifugal blower or the power supply of dry pump, it is ensured that the safety of experiment, it is to avoid energy waste.
Preferably, described shut-off valve system comprises two or more stop valve, be parallel relationship between described stop valve, and each described stop valve can individually control folding.
Arrange multiple stop valve can multiple sampler bags be inflated or aerofluxus simultaneously simultaneously, improve the efficiency of experiment.The quantity of stop valve can need to adjust according to concrete experiment.In one preferred embodiment, described stop valve is four.
This utility model can also make following improvement: described control panel is connected with siren.
During the fault such as leak air when control panel monitors system, gas cylinder air pressure is low, siren can send alarm automatically, reminds the attention of experimenter, it is to avoid security incident occurs.
Beneficial effect:
This utility model can switch between inflation loop and exhausting loop by adjusting the switch of electromagnetic valve, and inflation and aerofluxus all use same set of set of tubes system, greatly improve efficiency, have saved manpower；By each electromagnetic valve of control panel centralized Control, effusion meter and the break-make of electromagnetic valve, decrease substantial amounts of manual steps, solve pipe line parts abrasion, air-tightness, bad stability, the problem that Artificial Control gas flow error is big.
