Description
Technical field
The utility model relates to the technical fields of multiphase flow rates measurement, measure more particularly to using differential pressure type measuring principle
The measurement technology of moisture two phase flow.
Background technique
In the industrial process such as natural gas acquisition, conveying, the liquid mediums such as condensate and water flooding are often accompanied by pipeline.When
Gas phase is continuous phase, and when liquid phase is discrete phase, flow regime is moisture.The accurate metering tool of each phase flow rate in moisture flowing
There is important realistic meaning.Flow-measuring method based on differential pressure type principle is widely used.In traditional pressure vessel structure, lead
Pressure pipe is connect with the single pressure port on tube wall or ring casing.By taking venturi as an example, " cut with circle is mounted on according to GB/T2624.4
Differential pressure device in facial canal road measures the 4th part of full packages fluid flow: Venturi tube ", pressure bore dia is in 4mm~10mm range
It is interior and related to caliber, Throttling ratio, such as the upstream pressure bore dia of DN50 venturi only allows between 4mm~5mm.On
The measurement that traditional pressure vessel structure is suitable for monophasic fluid flow is stated, and is not suitable for vertical wet gas measurement.It is seen by experiment
It examines, when moisture flows through the DN50 ring casing pressure venturi for meeting the standard vertically, height is formd in connecting pipe at any time
The fluid column of variation brings error to the measurement of differential pressure.
Utility model content
The utility model provide it is a kind of for use throttling set measurement flux of moisture pressure vessel, be suitable for throttling set
Any pressure sensor location, which can prevent connecting pipe from being blocked by liquid and generate fluid column, to ensure that pressure and differential pressure
Reliable measurements.In order to solve the above technical problems, the technical solution adopted in the utility model is:
It is a kind of for measuring the throttling set pressure vessel of flux of moisture, suitable for the measurement of flux of moisture in vertical pipeline,
Pressure vessel shell and built-in connecting pipe including coating throttling set pressure position, which is characterized in that pressure position is close to be taken
The lower part of depressor shell offers the pressure slot being evenly distributed or porous radial pressure tappings for one week around pressure position, is taking
There are annular pilot channel, the pressure slot or pressure tappings to save between throttling set at splenium position and pressure vessel shell
It flows and is interconnected between medium channel and annular the pilot channel in device；It is offered in pressure vessel shell and the annular
The built-in connecting pipe that pilot channel is connected.
Preferably, annular pilot channel bottom be equipped with for accelerate the reflux of liquid and reduce dirt deposition step
Or slope.
The utility model is on the cross section of required pressure, using elongated pressure slot or porous radial pressure tappings pressure,
Packet is on the outside of pressure tappings with annular pilot channel, and passes through built-in connecting pipe and pressure, differential pressure pick-up in pilot channel roof
The measurement of pressure and differential pressure is realized in connection.Its working principle is that increasing pressure tappings by the length or quantity that increase pressure tappings
Sectional area, the liquid to enter pilot channel by pressure tappings provides the chance for flowing back to pipeline；Annular pilot channel have compared with
Big sectional area, equally can be to avoid the blocking of liquid, and the bottom of the channel is equipped with step or slope, for accelerating the reflux of liquid,
And reduce the deposition of dirt；The volume in pilot channel is larger, and pressure fluctuation caused by can rushing in, flowing out to liquid provides buffering and makees
With；There was only gas phase media at the top in pilot channel, its pressure is led to pressure/differential pressure sensor and realizes survey by built-in connecting pipe
Amount.
