System.Carry out this work, to ensure product quality, improve production efficiency, the development of the technology that advances science all has important work
With, particularly in energy crisis, current era that industrial production automation degree is the highest, effusion meter is in national economy
Status becomes apparent from effect.In industry spot, the instrument measuring fluid flow is referred to as effusion meter or flow meter.It it is Industrial Measurement
One of most important instrument in amount.Along with industrial expansion, accuracy and area requirement to flow measurement are more and more higher, in order to
Adapting to multiple use, various types of effusion meters are come out one after another, and are widely used in petroleum gas, petrochemical industry, water process, food
Savor the industries such as beverage, pharmacy, the energy, metallurgy, paper pulp papermaking and construction material.At present, common effusion meter is in measuring pipeline
During fluid flow, certainty of measurement is low.For solving this problem, Chinese patent CN 205373782U is public on 07 06th, 2016
Having opened a kind of whirlpool vortex precession flowmeter, including housing, described housing side is inlet, and opposite side is liquid outlet, at described shell
Internal from inlet to liquid outlet, it is disposed with contraction section, throat, expansion segment, described inlet is provided with pipe cyclone,
Described throat is provided with detecting element；Described pipe cyclone is fixed on case inside by packing；The material of described housing is engineering
Plastics；Described enclosure interior is provided with corrosion-resistant coating.But, in existing construction, in order to reduce fluid itself to measurement
Impact, it is desirable at least reserve the straight length into its nominal diameter three times, in some job sites, these conditions before vortex precession flowmeter
It is difficult to meet.
Therefore, based on these problems, it is provided that a kind of can reduce the fluid impact on measuring itself, thus rotation is effectively shortened
Before influent stream gauge, the intelligent vortex precession flowmeter of flow development length has important practical significance.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one can reduce fluid itself to measurement
Impact, thus effectively shorten the intelligent vortex precession flowmeter of flow development length before vortex precession flowmeter.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of intelligence vortex precession flowmeter, described intelligence vortex precession flowmeter includes that housing, described shell one end are inlet, separately
One end is liquid outlet, is disposed with contraction section, throat, expansion segment, described in described housing from inlet to liquid outlet
Inlet is provided with pipe cyclone, and described throat is provided with detecting element, and the front of described pipe cyclone is provided with guide shell, described in lead
The axis of flow cartridge overlaps with the axis of described inlet.
In above-mentioned intelligent vortex precession flowmeter, further, the edges at two ends of described guide shell carries out sharpening process.
In above-mentioned intelligent vortex precession flowmeter, further, the quantity of described guide shell is multiple.
In above-mentioned intelligent vortex precession flowmeter, further, the surface of described guide shell scribbles corrosion-resistant coating.
Advantage of the present utility model and good effect be:
1, this utility model is by being provided with guide shell, plays guide functions, is improved because of outside bending section etc. by fast guiding
Boundary's factor convection cell is measured and is produced impact, thus effectively shortens flow development length before vortex precession flowmeter.
2, the edges at two ends of this utility model guide shell carries out sharpening process, it is to avoid the convection cell of guide shell own produces shadow
Ring.
