Abstract
The utility model relates to an automatic oil-measuring device. A gas liquid inlet is arranged on a gas liquid separator; one side of the gas liquid separator is connected with a differential pressure transmitter through a pipeline; a gas outlet is arranged on the top of the gas liquid separator; the gas outlet is connected with a gas flowmeter; a liquid outlet is arranged below the other side of the gas liquid separator and is connected with an outlet of the gas flowmeter through an electrically operated valve and a tee joint; the differential pressure transmitter, the gas flowmeter and the electrically operated valve are connected with a programmable logic controller (PLC) control cabinet respectively through leads; the PLC control cabinet controls action of the differential pressure transmitter, the gas flowmeter and the electrically operated valve; the daily output of the liquid and the daily output of the gas can be calculated automatically; and when oil in a sealed container reaches a certain height, the differential pressure transmitter transmits a signal to the PLC control cabinet, so that the electrically operated valve is opened. The automatic oil-measuring device has the advantages of simple structure, convenience for operation and maintenance, accuracy in measurement and high automation degree.
Description
Technical field
The utility model relates to a kind of oil jug, particularly a kind ofly is used for the automatic oil-measuring apparatus that petroleum industry calculates day production fluid tolerance automatically.
Background technology
As everyone knows, the metering of oil well industry liquid gas all is the mode that adopts liquid level gauge method manual gaging, and it is big that it exists error, and artifical influence factor is many, and working condition is arduous, defective such as can not repeatedly measure.
Summary of the invention
The utility model provides a kind of and through differential pressure transmitter liquid level signal is passed to PLC (programmable controller) and carry out computing relatively for solving the control problem that exists in the known technology, thereby calculates the automatic oil-measuring apparatus of day production fluid tolerance automatically.
The technical scheme that the utility model is taked for the control problem that exists in the solution known technology is: it is characterized in that: it comprises gas-liquid separator, differential pressure transmitter, gas meter, PLC control box and lead; Have the gas-liquid import on the gas-liquid separator; One side of gas-liquid separator is connected with differential pressure transmitter through pipeline; The top of gas-liquid separator is a gas vent; Gas vent is connected with gas meter; The below of gas-liquid separator opposite side be liquid outlet it be connected with the outlet of gas meter with threeway through motorized valve, differential pressure transmitter, gas meter and motorized valve all are connected with the PLC control box respectively through lead, control differential pressure transmitter, gas meter and motorized valve through the PLC control box.
Advantage and the good effect that the utlity model has are: simple in structure, be convenient to operation and maintenance, and accurate measurement, automaticity is high, can calculate liquids and gases amount made in Japan automatically.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model;
Among Fig. 1: 1. gas-liquid separator, 2. differential pressure transmitter, 3. gas meter, 4.PLC control box, 5. lead, 6. gas-liquid import, 7. gas vent, 8. liquid outlet, 9. motorized valve, 10.A valve, 11.B valve, 12.C valve, 13.D valve, 14. outlets.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows, sees also Fig. 1.
As shown in Figure 1: this detects the oil mass device automatically and comprises gas-liquid separator 1, differential pressure transmitter 2, gas meter 3, PLC control box 4 and lead 5; Have gas-liquid import 6 on the gas-liquid separator 1; Gas-liquid gets in the gas-liquid separator 1 through gas-liquid import 6, and a side of gas-liquid separator 1 is connected with differential pressure transmitter 2 through pipeline, and the top of gas-liquid separator 1 is gas vent 7 and A valve 10; Gas in the gas-liquid separator 1 is discharged from gas vent 7; Gas vent 7 is connected with gas meter 3 through B valve 11, and the below of gas-liquid separator 1 opposite side is that liquid outlet 8 passes through D valve 13, motorized valve 9, threeway and C valve 12, and C valve 12 is connected with the outlet of gas meter 3; Another of threeway mouthful connection outlet 14; Differential pressure transmitter 2, gas meter 3 and motorized valve 9 all are connected with PLC control box 4 respectively through lead 5, through the action of PLC control box 4 control differential pressure transmitter 2, gas meter 3 and motorized valves 9, in closed container when oil mass reach a certain height; Sending signal to PLC control box 4 through differential pressure transmitter 2 through lead 5 opens motorized valve 9; PLC control box 4 also can at last, calculate daily output liquids and gases amount through the gas flow signal controlling gas flow of gas meter 3 automatically.
Its advantage is: simple in structure, be convenient to operation and maintenance, and accurate measurement, automaticity is high, can calculate daily output liquids and gases amount automatically.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
