Abstract
The utility model relates to a gas and liquid two-phase flow meter, which is used for metering on-line split-phase fluid of gas-liquid mixture. The utility model is composed of a volumetric flowmeter (1), a temperature transmitter (2), a pressure transmitter (3) and a corresponding signal output device. When utilized, the utility model can respectively meter the two-phase flow of gas and liquid in the gas and liquid mixed fluid in pipelines; the metering processes of the utility model is irrelevant with fluid state of the mixed fluid. The utility model has the advantages of high metering precision, simple equipment, easy manufacture, etc. The utility model is suitable for industries, particularly petroleum industries.
Description
The utility model relates to a kind of gas-liquid biphase flowmeter amount device that is used for the online phase-splitting metering of gas-liquid mixture fluid.
The online phase-splitting metering of gas-liquid mixture fluid especially has a crucial meaning industrial on petroleum industry.But because the flow velocity of gas phase and liquid phase is different, ratio is indefinite, has caused very big difficulty for the solution of this problem.It is reported that the U.S. has developed a kind of multi-phase flowmeter that is made of volumeter, gamma-ray densitometer, temperature sensor, pressure transducer and signal output apparatus, be used for the online phase-splitting metering of gas-liquid mixture fluid.But this flowmeter has not only caused the complex structure of instrument owing to used gamma-ray densitometer, cost an arm and a leg, and radioelement may produce certain harmful effect to health, therefore can't be entirely satisfactory.
The purpose of this utility model is to provide a kind of improved gas-liquid biphase flowmeter amount device, and this device has been simplified existing equipment, and cost is greatly reduced, and can eliminate the harmful effect of radioelement.
The utility model is realized in the following manner.It is made up of volumeter (1), temperature transmitter (2), pressure unit (3) and corresponding signal output apparatus, its structure and assembling feature are as follows: the top of volumeter (1) housing (10) or cover plate (6) is equipped with temperature transmitter (2) and pressure unit (3) side by side, and the two all extends to the inwall place of flowmeter shell (10) just; On the axle (5) of flowmeter (1) disk (9) is installed, 4 notches on it are corresponding with the position of 4 scraper plates (12) on the rotor (11) respectively, the cover plate (6) of flowmeter (1) is gone up the arc scale (8) that installation one has scale, it is provided with two two fork elements (4), (7) that can slide, and said elements constitutes signal output apparatus.When the two fork of the process of the notch on disk element, produce the signal of giving secondary instrument.The utility model is like this work: gas-liquid mixture fluid enters some airtight chamber between the inner scraper plate of flowmeter by inlet, because the volume of this chamber is time dependent, so can be, and measure the temperature and pressure of gas-liquid mixture fluid respectively in moment corresponding with it by temperature transmitter and pressure unit at two the different cumulative volumes that measure gas-liquid mixture fluid constantly respectively.Utilize the above-mentioned volume of surveying, temperature, pressure parameter and other known parameters to carry out computing, can obtain the volume and the flow of the gas phase and the liquid phase of the instrument of flowing through in a certain period by corresponding secondary instrument.
Advantage of the present utility model is that equipment is simple, be easy to make, and the flow state of metering process and gas-liquid mixture fluid is irrelevant, and measuring accuracy is higher, is suitable for industrial and especially applies on petroleum industry.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 removes partial sectional view behind the cover plate for volumeter.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
In the utility model, volumeter (1) can adopt U.S. Smith (producer) blade flowmeter, and the top of its housing (10) or cover plate (6) is arranged side by side two eyelets that are used for installing temperature transmitter and pressure unit; Disk (9) is installed on the axle of flowmeter (5), is uniformly distributed with 4 notches on the disk (9) along the circumference, corresponding with the position of 4 scraper plates (12) on the rotor (11) respectively; Arc scale (8) is provided with scale, and the centre has the saturating groove of an arc, and two fork elements (4), (7) are installed on the groove and slidably.Temperature transmitter (2), pressure unit (3) can adopt WZP-240 type platinum resistance thermometer sensor, temperature transmitter and BP-800 series diffused silicon pressure transmitter respectively.
Claims (2)
