Abstract
The utility model relates to a flow meter, in particular to an improved precession vortex flow meter. The improved precession vortex flow meter comprises a shell body (1). A detection area (10), a Venturi effect area (11) and a vortex eliminating area (12) are arranged start from one end of the shell body in sequence. The improved precession vortex flow meter is characterized in that a first piezo-electric crystal sensor (6), a second piezo-electric crystal sensor (7), a third piezo-electric crystal sensor (8) and a fourth piezo-electric crystal sensor are respectively arranged at two ends of two diameter lines which are mutually vertical on different sections in the detection area. The improved precession vortex flow meter has the advantages of being simple in structure, high in metering accuracy, shake-proof and capable of reducing gas pulsation.
Description
Technical field
The utility model relates to a kind of flowmeter, specifically a kind of improved precession spiral flowmeter.
Background technology
In the existing precession spiral flowmeter product, antivibration, poor anti jamming capability, crushing be large, can't eliminate interference, the accuracy of measurement that extraneous mechanical vibration or internal gas flow produce reduces, even can't be practical.
The utility model content
For the above, the utility model aim to provide a kind of simple in structure, the accuracy of measuring is high, reduced the improved precession spiral flowmeter of the interference of antivibration and gas.
For achieving the above object, a kind of improved precession spiral flowmeter of the present utility model, comprise housing, described housing one end begins to be followed successively by detection zone, Venturi effect district and racemization district, in detection zone not on the same cross section and mutually perpendicular two diameter line two ends on the first piezoeletric quartz sensor, the second piezoeletric quartz sensor are set respectively, the 3rd piezoeletric quartz sensor, the 4th piezoeletric quartz sensor.
Described housing opens the top setting and plays spigot.
Described spigot is spiral fashion.
Go back set temperature sensor and pressure transducer on the described housing.
Described racemization district end arranges the despinner assembly.
Adopt the improved precession spiral flowmeter of this programme, since in detection zone not on the same cross section and mutually perpendicular two diameter line two ends on the first piezoeletric quartz sensor is set respectively, the second piezoeletric quartz sensor, the 3rd piezoeletric quartz sensor and the 4th piezoeletric quartz sensor, also be that enclosure interior respectively arranges a piezoeletric quartz sensor at the diameter two ends, other one vertical with above-mentioned straight warp and not the diameter two ends on same cross section a piezoeletric quartz sensor respectively is set, be mutually 90 ° according to the housing central axis and evenly distribute thereby form four piezoeletric quartz sensors.Under the duty, adopt four and be mutually 90 ° of equally distributed piezoeletric quartz sensors, while test fluid vortex precession signal and pipe vibration and Pulsating Flow noise signal, the signal that transmits according to four piezoeletric quartz sensors, by the front panel processing circuit processes, output signal has become four times of signal on the original single-sensor, effectively weakens the interference that extraneous mechanical vibration cause.
So the utlity model has, the beneficial effect that the accuracy of measuring is high, reduced the interference of antivibration and gas.
Description of drawings
Fig. 1 is axial, cross-sectional view of the present utility model.
Fig. 2 is that Figure 1A-A is to the half-twist sectional view.
Embodiment
As depicted in figs. 1 and 2, a kind of improved precession spiral flowmeter of the present utility model, comprise housing 1, described housing one end begins to be followed successively by detection zone 10, Venturi effect district 11 and racemization district 12, described housing opens top spiral helicine spigot 2 is set, in detection zone not on the same cross section and mutually perpendicular two diameter line two ends on the first piezoeletric quartz sensor 6 is set respectively, the second piezoeletric quartz sensor 7, the 3rd piezoeletric quartz sensor 8 and the 4th piezoeletric quartz sensor 9, go back set temperature sensor 4 and pressure transducer 3 on the described housing 1, described racemization district 12 ends arrange despinner assembly 5.
In actual the use, air-flow is forced to rotation by playing spigot, make air-flow form eddy-currents, through piezoeletric quartz sensor, four piezoeletric quartz sensors are distributed in the housing intermediate detection district, and described four piezoeletric quartz sensors are responded to the cross section perpendicular to the whirlpool of conduit axis and are fixed on the housing.Four piezoeletric quartz sensors are mutually 90 ° according to the housing central axis and evenly distribute.Under the duty, adopt four and be mutually 90 ° of equally distributed piezoeletric quartz sensors, while test fluid vortex precession signal and pipe vibration and Pulsating Flow noise signal, the signal that transmits according to four piezoeletric quartz sensors, by the front panel processing circuit processes, output signal has become four times of signal on the original single-sensor, effectively weakens the interference that extraneous mechanical vibration cause.Eliminate the gas signal, and crushing lowers.
The useful result of this novel practical has improved the accuracy of measuring, and has effectively weakened the interference of antivibration and gas, have simple in structure, compact to design, specious, easy for installation, the advantage of long service life.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering technical personnel in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
