Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of oil-water metering precision high outlet profit two-phase flow measurement system.

The purpose of this utility model is achieved in that outlet profit two-phase flow measurement system, comprises the transverse tube of first electronic balance, second electronic balance and a horizontally set, on first electronic balance storage tank is set, and on second electronic balance water tank is set; The top of described transverse tube connects vertical level balance pipe, intermediate glass pipe and the glass trap tube that is provided with, the upper end of level balance pipe is provided with the glass valve, the upper end of intermediate glass pipe is provided with loam cake, on cover and place common electrode, the upper end of glass trap tube connects first glass tube and second glass tube, the middle part of first glass tube and second glass tube is connected by the 3rd glass tube, the second glass tube internal fixation connects trigger electrode, the lower end of trigger electrode is higher than the lower end of described common electrode, and the second glass tube external fixation connects photoelectric sensor; Connect flowline on described second glass tube, an end of flowline is arranged between the lower end of photoelectric sensor and trigger electrode, and the other end of flowline is arranged in the described storage tank; First pneumatic valve and oil well pump are set on the described flowline, and the signal output part of photoelectric sensor is connected with first pneumatic valve; Also connect drainpipe on the described transverse tube, the other end of drainpipe is arranged in the water tank, and second pneumatic valve is set on the drainpipe.

Based on oil, water-mass density difference, oil, water are separated in real time in meter.Utilize the smart electronics liquid-level controller (LLC), the High Accuracy Control oil-water separation interface.The output water conservancy is discharged with second pneumatic valve, by the second electronic balance calculating correction values output; Output oil is controlled first pneumatic valve by photoelectric sensor, by first electronic balance measure oil mass what, again by the accurate oil well pump of system controlled by computer, both precision measurement oil offtake that combine.Output oil measurement precision 0.1ml of the present utility model, output water measuring accuracy 0.01ml, data of the present utility model all can be passed through computer data acquisition, the overall process full-automation, alleviate personnel labor intensity, and have simple to operation, measuring accuracy is high, be not subjected to factor affecting such as oil sample temperature, density, reduces advantages such as personal error.

After making things convenient for off-test the water in the meter is discharged, the below of transverse tube connects blow-down pipe, connects atmospheric valve on the blow-down pipe.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Among the figure, 1 second electronic balance, 2 water tanks, 3 first electronic balances, 4 storage tank, 5 oil well pumps, 6 first pneumatic valves, 7 photoelectric sensors, 8 second glass tubes, 9 trigger electrodes, 10 first glass tubes, 11 the 3rd glass tubes, 12 level balance pipes, 13 glass valves, 14 loam cakes, 15 common electrodes, 16 transverse tubes, 17 intermediate glass pipes, 18 blow-down pipes, 19 atmospheric valves, 20 second pneumatic valves, 21 drainpipes, 22 flowlines, 23 glass trap tubes.

Embodiment

As shown in Figure 1, be outlet profit two-phase flow measurement system, comprise being provided with on storage tank 4, the second electronic balances 1 on transverse tube 16, the first electronic balances 3 of first electronic balance 3, second electronic balance 1 and a horizontally set water tank 2 is set.The top of transverse tube 16 connects the vertical level balance pipe 12 that is provided with, intermediate glass pipe 17 and glass trap tube 23, the upper end of level balance pipe 12 is provided with glass valve 13, the upper end of intermediate glass pipe 17 is provided with loam cake 14, place common electrode 15 on the loam cake 14, the upper end of glass trap tube 23 connects first glass tube 10 and second glass tube 8, the middle part of first glass tube 10 and second glass tube 8 is connected by the 3rd glass tube 11, second glass tube, 8 internal fixation connect trigger electrode 9, the lower end of trigger electrode 9 is higher than the lower end of common electrode 15, and second glass tube, 8 external fixation connect photoelectric sensor 7.Connect flowline 22 on second glass tube 8, an end of flowline 22 is arranged between the lower end of photoelectric sensor 7 and trigger electrode 9, and the other end of flowline 22 is arranged in the storage tank 4.First pneumatic valve 6 and oil well pump 5 are set on the flowline 22, and the signal output part of photoelectric sensor 7 is connected with first pneumatic valve 6.Also connect drainpipe 21 on the transverse tube 16, the other end of drainpipe 21 is arranged in the water tank 2, and second pneumatic valve 20 is set on the drainpipe 21.The below of transverse tube 16 connects blow-down pipe 18, connects atmospheric valve 19 on the blow-down pipe 18.

Principle of the present utility model is: in advance by level balance pipe 12 with fills with water in the transverse tube 16, make intermediate glass pipe 17 fills with water.Oil and water enter from first glass tube 10, because the effect of density, oil float is above water.When liquid level rises to photoelectric sensor 7 inductions place, and oil water surface is positioned at the below of trigger electrode 9 lower ends, opened by photoelectric sensor 7 controls first pneumatic valve 6, thereby oil well pump 5 begins oil pumping, because the top is oil, can be by the fuel-displaced quality of first electronic balance, 3 meterings; And after oil water surface rises to certain altitude, make common electrode 15 and trigger electrode 9 connect, trigger second pneumatic valve 20 to open, thereby pass through the quality that second electronic balance 1 measures water.
