The specific embodiment
Please refer to the Fig. 1 in the Figure of description, be oil gas metering device embodiment flow chart.The oil gas metering device that the utility model proposed utilizes eliminator to separate gas-liquid automatically with the float linkage, adopt bivalve to control the gas-liquid discharging respectively, gas-liquid adopts the flow meter metering respectively, this oil gas metering device comprises gas-liquid inlet valve 6, gas liquid outlet valve 7 and bypass valve 8, and this oil gas metering device also comprises: float linkage, eliminator 1, gas flowmeter 5, fluid flowmeter 9, gas phase control valve 11 and liquid phase control valve 10.Eliminator 1 is connected with gas-liquid inlet valve 6.Gas flowmeter 5 is connected with eliminator 1 upper end.Fluid flowmeter 9 is connected with eliminator 1 lower end.Gas phase control valve 11 two ends are connected with gas flowmeter 5 and gas liquid outlet valve 7 respectively.Liquid phase control valve 10 two ends are connected with fluid flowmeter 9 and gas liquid outlet valve 7 respectively.
This float linkage comprises connecting rod 3, valve rod 1, valve rod 2 15, float 2 and counterweight 4.Valve rod one 14 two ends are connected with connecting rod 3 and liquid phase control valve 10 respectively, are used to control liquid phase control valve 10.Valve rod 2 15 two ends are connected with connecting rod 3 and gas phase control valve 11 respectively, are used to control gas phase control valve 11.Float 2 is connected with connecting rod 3 one ends, is arranged in the eliminator 1.Counterweight 4 is connected with connecting rod 3 other ends.
As shown in Figure 1, the gas-liquid mixture of oil well output through gas-liquid inlet pipeline 12, enters eliminator 1 by the gas-liquid inlet valve of opening 6, relies on density contrast to carry out gas-liquid separation in eliminator 1.Before normally liquid level was not set up, gas measured through gas flowmeter 5 along the tracheae of eliminator 1 upper end, and discharge from gas liquid outlet valve 7 through gas phase control valve 11 on gas road, metering back, and the spool of liquid phase control valve 10 is in closed condition at this moment.After liquid level rises above the liquid level lower limit gradually, along with the continuation of liquid level is risen, the float linkage clockwise rotates the rotating shaft of connecting rod 3, the valve rod 1 of liquid phase control valve 10 is upwards mentioned, then the spool of liquid phase control valve 10 is opened gradually, liquid measures through fluid flowmeter 9 along the fluid pipeline of eliminator 1 lower end, discharge from gas liquid outlet valve 7 through liquid phase control valve 10 on liquid road, metering back, simultaneously, the valve rod 2 15 of gas phase control valve 11 moves down, the spool of gas phase control valve 11 turns down and sets up the needed pressure of discharge opeing gradually, the liquid level of eliminator 1 and pressure will enter normal duty thereupon, and float 3 moves up and down under the effect of liquid level and pressure, impel liquid phase control valve 10 and gas phase control valve 11 to open and closure, gas-liquid is discharged in circulation.Gas and liquid flow to gas liquid outlet pipeline 13 after gas liquid outlet valve 7 is discharged.
The oil gas metering device that the utility model proposed utilizes the float linkage to regulate the gas-liquid two-phase liquid level, and two valve rods that have on the connecting rod are controlled the motion of gas, two spools of liquid simultaneously, has realized the interlock adjusting.Gas, liquid two-phase are discharged by gas phase control valve 11 and 10 two separate valve of liquid phase control valve respectively, and valve body structure is simple, for the liquid phase control valve 10 of easy pollution, is convenient to unpick and wash and safeguard.Large-minded and liquid measure is little, narrow-minded and liquid measure big, tolerance is all big with liquid measure, tolerance is all little with liquid measure, even tolerance is few or go to zero and under the big various operating modes of liquid measure, liquid level can both obtain steadily reliable control.The gas of discharging, liquid two-phase are respectively by gas flowmeter 5 and fluid flowmeter 9 meterings, accurate measurement.The gas-liquid separation process is to separate automatically, need not manual monitoring and regulates, and manages convenient.
Eliminator 1 can adopt various forms such as spiral-flow type and gravity.The float linkage can be designed to the float linkage of drive gas phase control valve, liquid phase control valve, also can be designed to drive simultaneously the association type float linkage of gas phase control valve, liquid phase control valve.Gas flowmeter and fluid flowmeter can be selected universal flow for use.In addition, bypass valve 8 is directly connected between gas-liquid inlet pipeline 12 and the gas-liquid outlet valve 7, and bypass valve 8 cuts out under this device normal operating conditions, and bypass valve 8 can be opened when needed, has increased the flexibility of device, is beneficial to maintenance, safeguards circulation safety.
Though technology contents of the present utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this skill person; do not breaking away from spirit of the present utility model a little change and the retouching done; all should be covered by in the category of the present utility model, therefore protection domain of the present utility model is as the criterion when looking claims person of defining.
