Two, background technique
At present, oilfield metering or the general method that adopts separate measurement of production metering.The pressure control of separate measurement method two phase separator generally adopts level pressure control or transformation controlling method.Level pressure control is with self-erecting type modulating valve control separator pressure, liquid level with float liquid level modulating valve control separator, the pressure of separator and liquid level are two-way control, this controlling method shortcoming is that flow process complexity, installation and maintenance workload are big, and when the gathering network pressure surge, need manually the adjust pressure of self-erecting type modulating valve brings inconvenience to production management.Transformation control adopts float liquid level oil gas modulating valve to control the pressure and the liquid level of separator simultaneously, float liquid level oil gas modulating valve is by ball float, linkage mechanism and interflow three-way control valve are formed, this controlling method advantage is that flow process is simple, production management is convenient, its shortcoming is that float liquid level oil gas modulating valve is connected the nearly 30kg flange of DN300 of needs and 16 M27 bolts with separator, float is installed in the separator, when the ball float corrosion, shrivel, maintenance and installation workload were very big when the fly rod bar fractureed, and float liquid level oil gas modulating valve and separator installation dimension are bigger, and the whole skid volume of measuring apparatus is bigger.
Three, summary of the invention
The purpose of this utility model is to adopt connecting pipe principle to design a kind of floating-tube type oil gas modulating valve, and on float, set up magnetic patch, on floating drum, set up magnetic and turn over the pearl scale plate, the supporting use of this valve and deaerator, realize the automatic control of separator pressure and liquid level, pressure control is transformation control, and can show level change on the spot.
The technical solution of the utility model realizes in the following manner:
A kind of floating-tube type oil gas modulating valve that is used for oilfield metering separator and production separator pressure, automatic control of liquid.It is characterized in that being provided with air valve seat (gas outlet) in the upper end portion of floating drum, be provided with fluid valve seat (liquid outlet) in the underpart of floating drum, the week side is provided with gas inlet in the bottom of air valve seat, the week side is provided with liquid-inlet on the top of liquid valve seat, two imports in one plane are connected with deaerator gas, liquid outlet respectively; Is provided with gas valve core in the floating drum, the middle part is provided with the magnetic float, and the bottom is provided with the liquid spool, is connected one with valve rod between spool and the float, and the gas outlet is connected with air pipe, and liquid exports and is connected floating drum, valve seat, spool and float coaxial line with liquid pipeline.
The gas of floating-tube type oil gas modulating valve, liquid spool, valve rod and float all adopt removable connection, and valve seat is threaded with the floating drum employing or flange is connected, and gas, liquid modulating valve are equal percent regulating characteristic, establish magnetic patch in the float, and floating drum peripheral hardware magnetic turns over the pearl scale plate.
The utility model floating-tube type oil gas modulating valve is compared with existing float liquid level oil gas modulating valve has following characteristics:
1, has pressure, liquid level control function, have the liquid level function for monitoring again;
2, floating-tube type oil gas modulating valve volume is little;
3, with deaerator, the supporting use of measuring instrument, its integral installation size is little, and flow process is very simple, is easy to realize the miniaturization of Oil-gas Separation measuring apparatus;
4, set up magnetic patch in the float, be provided with on the floating drum and turn over the pearl monitor board, can observe the separator liquid level.
5, adopt flange or be threaded between deaerator and the floating-tube type modulating valve, form tandem product easily, and can combination in any.

Five, embodiment
For further disclosing the technical solution of the utility model, below in conjunction with the explanation accompanying drawing, by
Embodiment elaborates.
A kind of floating-tube type oil gas modulating valve that is used for oilfield metering separator and production separator pressure, automatic control of liquid.It is characterized in that being provided with air valve seat 12 (gas outlet 1) in the upper end portion of floating drum 3, be provided with liquid valve seat 6 (liquid outlet 5) in the underpart of floating drum 3, the week side is provided with gas inlet 2 in the bottom of air valve seat 12, being provided with liquid-inlet 4, two imports in the top of liquid valve seat 6 week side is connected with deaerator gas, liquid outlet respectively; Be provided with gas valve core 11 in the floating drum 3, the middle part is provided with magnetic float 9, and the bottom is provided with liquid spool 7, is connected one with valve rod 8,10 between spool 7,11 and the magnetic float 9, and gas outlet 1 is connected with air pipe, liquid
Floating-tube type oil gas modulating valve utilizes connecting pipe principle and designs, with the supporting use of deaerator, modulating valve gas import 2, liquid-inlet 4 and separator gas outlet, liquid outlet are respectively with flange or be threaded, magnetic float 9 in the floating-tube type oil gas modulating valve is with (decline) rise (decline) of rising of liquid levels (being the separator liquid level) in the floating drum 3, drive the motion of gas valve core 11, liquid spool 7 simultaneously and change gas, flow quantity, and magnetic turns over the pearl scale plate and changes with the separator liquid level.When the turnover liquid measure of separator and tolerance were constant, liquid level stabilizing was on a certain position; When the liquid measure that enters separator or tolerance change, and when liquid level is risen, the float come-up, drive on gas, the liquid spool and move, the gas outlet turns down and the liquid outlet is opened greatly, air displacement is reduced and lifting rate increases, liquid level descends, and float is stabilized on the higher relatively liquid level again; When the liquid measure that enters separator or tolerance change, and when liquid level is descended, float drive spool moves down the gas outlet is opened greatly, the liquid outlet turns down, air displacement is increased and lifting rate reduces, when liquid measure and the tolerance of turnover separator equates, liquid level will be stabilized on the original low position again.Along with liquid measure that enters separator or tolerance change, float drives spool and produces corresponding action, thereby liquid level is kept relative stability like this.
