Description
Technical field
The present invention relates to a kind of device detecting elbow meter, belong to technical field of measuring equipment.
Background technology
Elbow meter measures product as one, and its advantage has obtained measuring the accreditation on boundary, and is gradually widely used in industry,
Multiple field such as public utilities.The advantage of elbow meter is mainly reflected in that principle is reliable, simple in construction, energy-saving and cost-reducing, maintenance is few
Aspect, the primary sensing element Bending Tube Sensor of elbow meter is applicable to severe industrial environment, for high temperature, high pressure, humidity,
The various severe field condition such as dust, vibrations has good applicability, can be to φ 20-φ 2000mm, and the biggest pipeline is carried out accurately
Flow measurement.Under the cooperation of intelligent instrument specially for same or modular converter, can meet electric power, heating power, metallurgy, iron and steel, oil, chemical industry,
In the flow measurement of the liquid of industry-by-industry, gas and the steam such as machinery, weaving, papermaking, pharmacy, food processing and public utilities
Demand.Its application and prospect is wide.
The operation principle of elbow meter is that fluid flows through a pipeline under a certain pressure condition of a certain temperature, when it flows through bend pipe, and should
Fluid will do corresponding circumference rotary motion.Forcing eddy flow scheduling theory according to fluid, fluid circles with solid in space in pipeline
Circling similar under state, therefore fluid will necessarily produce pressure differential on bend pipe madial wall and lateral wall, this pressure extent with
The factor such as the flow velocity of fluid, the density of fluid and the radius of curvature (the namely radius of curvature of bend pipe) that circles is relevant, in other words,
Fluid flow velocity in pipeline is fluid density, the radius of curvature of bend pipe and bend pipe madial wall and the factor such as the pressure differential that produces on lateral wall
Function.
Wherein bend pipe radius of curvature can obtain by accurately measuring, and the fluid density flowing through bend pipe can be by the temperature of fluid, pressure
Isoparametric mensuration is tried to achieve exactly, and the pressure extent that in bend pipe, outside produces directly can be recorded by high-precision differential pressure transmitter,
Thus can calculate fluid flow velocity in pipeline, then flow velocity is multiplied by the sectional area of pipeline, i.e. can determine that the flow of fluid.
During the making and use of elbow meter, the certainty of measurement of elbow meter and repeatable playback accuracy can be by bend pipe streams
The impact of the quality of gauge own, including the perpendicularity of elbow meter, levelness, torsion resistance, out-of-roundness, the uniformity etc., is also subject to simultaneously
To the impact of installation quality, therefore the calibrating to elbow meter is the requisite important step during making and using.
Existing Flowmeter Verification System is the system for examining and determine straight length flow meter, and pipeline arrangement is linear pattern, i.e. before system
After straight length, calibrating section, system, the axis of straight length is respectively positioned on same straight line, is not specifically designed for the verification system of elbow meter,
Therefore it is highly desirable to design the calibrating installation of a kind of special checking elbow meter.
Summary of the invention
The technical problem to be solved is to provide a kind of device examined and determine elbow meter specially.
The present invention is to realize above-mentioned purpose by following technical solution:
The device of a kind of checking elbow meter, it is made up of water pump, voltage-stablizer, instrumentation, verification table, pond, water pump, voltage stabilizing
Having water-filled pipe connection between device, instrumentation, verification table, pond for circulation line, elbow meter is placed on verification table, two ends
It is connected with instrumentation and pond by water-filled pipe respectively.
The device of above-mentioned checking elbow meter, the axis of the described water-filled pipe (front straight length) being connected with elbow meter front end be perpendicular to
The axis of the water-filled pipe (rear straight length) that elbow meter rear end connects, and in the same plane.
The device of above-mentioned checking elbow meter, there is adpting flange the junction between described water-filled pipe and each several part.
The device of above-mentioned checking elbow meter, between voltage-stablizer and instrumentation, between instrumentation and verification table, verification table and water
It is fitted with valve on water-filled pipe between pond.
The device of this checking elbow meter, can be placed on elbow meter on verification table, and two ends connect instrumentation and water respectively
Pond, starts water pump, and water is circular flow in device, can detect the performance of elbow meter, and this device has been filled up does not has special detection
The blank of the calibrating installation of elbow meter.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Figure mark as follows: water pump 1, voltage-stablizer 2, instrumentation 3, verification table 4, front straight length 5, rear straight length 6, bend pipe stream
Gauge 7, pond 8, water-filled pipe 9, valve 10.
Detailed description of the invention
It is clearly understood to make present disclosure be easier to, below according to specific embodiment and combine accompanying drawing, the present invention is made into one
Step detailed description.
As shown in drawings, the present invention is the device of a kind of checking elbow meter, and it is by water pump 1, voltage-stablizer 2, instrumentation 3, calibrating
