Description
Technical field
The invention belongs to air-liquid separate measurement technical fields more particularly to a kind of gas-liquid two-phase of normal pressure state to count in real time
Measure device.
Background technology
Air water two-phase flow measurement is to be badly in need of solution and long-term unsolved problem in many industrial productions.Biphase gas and liquid flow
Two-phase in body all has deformable boundary, and wherein gas phase and liquid phase has compressibility again, this is other various types
Two phase flow (gas solid, liquid liquid, liquid are solid) do not have, such as saturated vapor metering, in mutually synthermal, liquid under pressure ingredient
Ratio can be from 0% (dry saturated steam) to 100% (wet saturated steam), and fluid density changes very greatly, and tradition is mended according to temperature, pressure
The method for repaying determining density can not accurately calculate density.But due to not finding feasible method, it can only assume that a steam is wet
Degree, this is very big on flowmeter accuracy influence, and humidity is bigger, and error is bigger, this so that the quantitative study of gas-liquid two-phase is more each than other
Class two-phase flow is increasingly complex.

The air water two-phase flow measurement device used can not be applied directly in laboratory scientific research flow；
(2) using moisture trap by air water two-phase laminated flow into single-phase gas and liquid, and then using gas mass flow
The flow that gauge and electronic balance measure each phase respectively is the metering method that current laboratory scientific research flow is most widely used.It should
Although method has many advantages, such as that reliability is high, precision is high, this method real-time is poor, is not suitable for decomposition of hydrate reality
It tests, rock core displacement test etc. is to the flow of real-time measuring requirement harshness；

It is equipped with corresponding stop configurations.The setting of connecting rod 25 pushes plug 24 to be used for for assisting reading data and pushing plug 24
Enter the gas in the first volume weight tube of preceding discharge in fluid.Counterweight 23 is lifted on 25 lower section of connecting rod by a lead, is used for
Pass through frictional force, the first volume weight tube 2 between the O-ring and the first volume weight tube 2 on the gravity of 23 dummy piston of counterweight itself, piston
Vacuum section is to the suction of plug 24 so that first piston 5 is in the state of a stress balance, the gas-liquid that upstream is come at this time
When fluid-mixing enters the first volume weight tube 2, micro fluid can cause first piston 5 to move downward；If the fluid entered is
Interruption, then, will since there are vacuum degrees inside the first volume weight tube 2 after the fluid of entrance causes first piston 5 to move downward
Stop motion and restore force balance state again quickly.Above-mentioned setting avoids for first piston 5 to be made to realize stress balance
Fluid is caused stress, its volume size is influenced, further reduces error.

Setting, not only realize the real time measure of gas-liquid two-phase fluid, while can also be realisation according to its range of the flow-rate adjustment of fluid
By force, reliability is high, precision is high；
2nd, measurement is not being changed by the setting of the second mixing weighing device and the second load-bearing machine substantially respectively in the present invention
The measurement range of small-range and wide range is increased in the case of precision, further improves the accurate of gas-liquid mixture fluid metering
Property；
3rd, above device is integrated, is combined into plurality of optional range by the setting of three two position three-way valves in the present invention, and
With hop controller, realize the present apparatus automatically control and the automatic adjustment of range；
4th, in the present invention, quick coupling 19 is set by the entrance in air inlet pipe, user is made not need to tool just can be real
Existing pipeline unicom or disconnection reduce the experimental work amount of user；
5th, in the present invention, by the O-ring on the setting gravity of dummy piston itself of counterweight 23, piston and volume weight tube it
Between frictional force, container vacuum part is to the suction of piston so that piston is in a force balance state, reduces and gas-liquid is mixed
Close the influence of fluid volume；
6th, in the present invention, by crossing the setting of cannot restrain one's anger 11 device of decanter of water, in further purification ＆ isolation gas
Liquid component so that the precision of measurement is more accurate.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe is described in detail the present invention with reference to foregoing embodiments, it will be understood by those of ordinary skill in the art that：Its according to
Can so modify to the technical solution recorded in foregoing embodiments either to which part or all technical features into
Row equivalent replacement；And these modifications or replacement, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
