Through the above design, the present invention can be brought the following benefits: a kind of automation organic gas, which fills, adopts dress
It sets, solves the problems, such as that flow accurate cannot be controlled when filling gas production, and be combined as a whole inflation with gas production, reduce difference
The instrument error generated between metering device effectively raises the accuracy of detection.The valve is solenoid valve, flow control
Device is gas mass flow controller, and automation organic gas fills device for picking using solenoid valve control valve opening and closing, utilizes flow
The quality of controller calculating gas.
In a preferred embodiment of the present invention, described device pipeline communicates, and inflation, gas production can be run simultaneously, does not do mutually
It disturbs, the gas production simultaneously of double gas circuits can be controlled separately the opening and closing of each solenoid valve, realize segmentation leak detection.
In a preferred embodiment of the present invention, gas culture storehouse be totally-enclosed working environment, sample gas not by
The influence of air pressure, temperature and external environment.
Compared with prior art, the beneficial effects of the invention are as follows the effective accuracy for improving detection of the invention, reduce
The instrument error generated between different metering devices, inflation, gas production run simultaneously, do not interfere with each other, the gas production simultaneously of double gas circuits, device
The opening and closing of each solenoid valve is individually controlled, realizes segmentation leak detection, totally-enclosed gas culture storehouse effectively avoids sampler bag from bursting sack
Problem, device automatic collection, without artificial, application prospect is extensive.
