The present invention adopts the following technical scheme that：
Accurate measurement gas-liquid ratio method of the present invention is implemented using accurate gas liquid ratio measurement device.The accurate survey
Determine gas liquid ratio device, mainly by pipeline, flow rate fine-tuning valve, rubber stopper, buffering flask, liquid measure meter, liquid nitrogen cooling bath, gas gauge,
Enter gas pipeline, outlet line, pedestal composition.Come from air source to take the general pressure of liquid gas phase higher, if directly passing through pipeline
Into follow-up measuring device, it is easy to which, because the high pressure of fluid, high speed moment burst device, even if not bursting, high velocity stream also can
Seriously affect measuring accuracy.Therefore it needs to find a kind of method being substantially depressured reduction of speed, can be reached by introducing flow rate fine-tuning valve
To the effect.Air source can reduce gaseous pressure and flow velocity after flow rate fine-tuning valve regulation before measuring, obtain pressure it is relatively low,
The slow air source of flow trim increases Security of test and accuracy, therefore introduces existing flow rate fine-tuning valve.It is come out from the valve
Take liquid gas phase via rubber stopper it is fixed enter gas pipeline after, into buffering flask in the middle part of large space can drastically expand, fully
Decrease temperature and pressure, entering cooling liquid in gas pipeline can directly drop in liquid measure meter, and residual fluid can be under the effect of peripheral cooling bath
It is further cooling.Gas-liquid can be made to be completely separated by the method for this abundant decompression cooling, the liquid isolated enters liquid measure meter,
And gas phase enters gas gauge via outlet line.Entire agent set buffering flask, liquid measure meter, the pedestal of measuring is tied using integration
Structure design, close air source after to be measured, the agent sets such as liquid measure meter taken out from liquid nitrogen cooling bath, etc. liquid measures meter, gas
Gauge directly reads data after restoring to room temperature, you can obtains accurate gas liquid ratio.
Compared with existing gas-oil ratio determination techniques and device, it is an advantage of the invention that：
By introducing existing flow rate fine-tuning valve in 1 present invention, it can more finely control take liquid gas by this method
The flow and pressure of phase, keep air source steadily slow, reduce security risk, increase measurement accuracy.
A kind of new method for entering gas pipeline and outlet line controlled at rubber stopper is devised in 2 present invention, is allowed into tracheae
Line extends in the middle part of buffering flask, and outlet line is just passed through rubber stopper, pulls open the vertical distance of two pipelines, this method can prevent two pipelines
Between form convection current, gas phase can be reduced to greatest extent and take liquid to outlet line, measuring accuracy can be greatly improved.
The method for buffering flask volume by expansion in 3 present invention, can drastically expand and take liquid gas phase, and liquid is taken to reduce
Gas phase temperature pressure, and liquid phase is further cooled down by peripheral liquid nitrogen cooling bath, it is convenient for gas-liquid separation, improves measuring accuracy.
Liquid measure meter just can avoid being transferred to other container measurement with scale convenient directly reading, the method in 4 present invention
When the second order error that generates, and liquid measure meter diameter is thinner, can increase liquid phase accuracy of reading, and the method is convenient and efficient and precision
It is high.
