Description
Technical field
The utility model relates to gas volume, flow measurement storage facilities field, specifically a kind of gas volume, flow measurement Storage Box.
Background technology
Detect at rock pyrolysis air absorbing body flow and volume, detect at aerogenesis chemical reaction, seal in the process such as parts Leakage inspection and the detection of fermentable aerogenesis, need flow and the volume of gas-monitoring, many employings " flowmeter method " detect volume, the flow of gas in the process at present, but this mode existing defects.1, the best gas meter in the world is as U.S. SIERRA, Switzerland E+H/ grace Si Haosi flowmeter, Switzerland SENSIRION high-precision gas mass flowmeter, the nominal of highest detection precision can reach 1 ‰, really be integrated into instrument only 2-3 ‰, if meet 1000ml/ minute, then 1-2ml per minute is precision measure ultimate value, when scene inspection product per hour actual be 1-2ml flow time, flowmeter accuracy is inadequate, and select the range of 100ml/ hour, flowmeter accuracy can reach, but maximum flow 1000ml/ minute, obvious flowmeter outrange is not suitable with maximum flow.2, the demarcation of flowmeter is all demarcate with under elementary gas standard conditions in addition, and spot sampling gas complicated component, volume, the flow of elementary gas demarcation can not be suitable for gas on-site flow monitoring complicated and changeable.3, when detection flow is very little, " flowmeter " inner flow passage hole is very little, and tested gas has ash content, water vapor component, once there be these compositions to pollute in flowmeter, flowmeter detects and departs from normal inefficacy very soon.4, leakage rate is the parameter of the intact situation of constant system sealing day, " flowmeter detection method " just flows, suck-back cannot judge, sometimes do not have actual flow to produce, the gas that just expands with heat and contract with cold in connecting line space breathes heavily shake, and cmf record result is but continuous rising." flow detection method " cannot meet measurement requirement under above 4 kinds of conditions.
Current use glass tube liquid level acquisition method is also a kind of traditional detection method, its measuring equipment adopts the method for pyrolysis cucurbitula, linker artificial equilibrium glass cylinder, there is following shortcoming in measuring method: 1), experimental facilities is huge, measure and often organize parallel connection more, the scattered glass component of assembling carrying is frangible, cannot be inverted, must dismantle, cannot whole Transporting; 2), operation level balance work heavy (hitless operation in artificial 24 hours) is measured; 3), reading typing heavy (uninterrupted typing in artificial 24 hours); 4), measuring period is long, liquid level scale reading low precision (estimate number completion certificate, cannot avoid the spherical surface error that liquid and graduated cylinder produce); 5), hold-up saline solution evaporation in graduated cylinder, absorb and dissolve detected gas or moisture interference final reading book; 6) gas dust of, sampling disturbs; 4), atmospheric pressure interference (height above sea level is relevant with measurement data); 5), environment temperature interference (measurement data is relevant with variation of ambient temperature).
Instantly also useful saturated aqueous common salt bottle atmosphere storage method, the bad equally saline solution of avoiding of the method adsorbs the dissolving of gas, the interference of saline solution self evaporation to gas volume, gas componant.Equally also be not easy to realize unartificial reading, reading is forbidden.Simultaneously also there is vial not turn-over, have leaked liquid, the problem that frangible, carrying is inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of gas volume, flow measurement Storage Box, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of gas volume, flow measurement Storage Box, comprise housing, barrier film is provided with in described housing, and barrier film is fixedly linked by the inwall of gluing device and housing, the upper and lower of barrier film is respectively control chamber and storage chamber, and control chamber is not communicated with mutually with storage chamber, in control chamber, be marked with control liquid; Described control chamber and storage chamber are respectively equipped with control chamber valve and storage chamber valve.
As further program of the utility model: described housing adopts metal or plastics or glass to make.
Compared with prior art, the beneficial effects of the utility model are: the utility model cost is little, cheap, easy to carry, gas purity can be ensured, service condition is not harsh, environment is unrestricted, its accuracy is also higher, relative to existing " flowmeter method measuring equipment ", it is more convenient that the utility model uses, efficiently, precisely, relative to " glass tube liquid level acquisition method ", the removable inversion of the utility model, there is no leaked liquid, volume is little, non-friable, convenient in carrying, liquefied gas is not had to evaporate absorbing phenomenon, liquid does not contact inspection product can not pollute inspection product, reading can pass through electronic-weighing reading, more accurate relative to liquid level scale reading, can realize that spreadsheet is non-artificial to be filled in, people is avoided to be typing mistake etc., reduce labour intensity, raise the efficiency, relative to saturated common salt water bottle atmosphere storage method, the utility model can avoid saline solution to adsorb the dissolving of gas, saline solution self evaporation is to gas volume, the interference of gas componant, equally also can accomplish unartificial reading, reading is accurate, Storage Box can be inverted, there is no leaked liquid, non-friable, convenient in carrying.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of gas volume of the utility model, flow measurement Storage Box.
In figure: 1-housing, 2-barrier film, 3-gluing device, 4-control chamber, 5-storage chamber, 6-control liquid, 7-control chamber valve, 8-storage chamber valve.
