Description
Technical field
The present invention relates to measuring instrument technical field, particularly a kind of magnetic displacement suspended body flowmeter.
Background technology
Present suspended body flowmeter has simple in structurely, but its measuring accuracy is very poor, has precision high, but structure is very complicated.More a kind of magnetic coupling suspended body flowmeter; This flowmeter is equipped with magnet rotor outside Taper Pipe; Attract the displacement of the lines of float is changed into the angular displacement of rotor through the magnet in magnet rotor and float coupling, become the corresponding discharge demonstration to corresponding angular with angular transducer again, and location variation converts angle variable quantity to and can produce nonlinearity erron; Complicated in mechanical structure, poor anti jamming capability.
Summary of the invention
The objective of the invention is for solving the problems of the technologies described above a kind of magnetic displacement suspended body flowmeter that shows flow through the magnetic potential in-migration of invention design.
The present invention realizes as follows: said magnetic displacement suspended body flowmeter, comprise Taper Pipe, and the two ends of Taper Pipe are provided with flange; Overhead gage and lower baffle plate are arranged in the Taper Pipe; Fluid media (medium) can see through two baffle plates up and down, is provided with conduit between two baffle plates, is with float on the conduit; Leave annular space between float and Taper Pipe; Be provided with waveguide filament in the conduit, waveguide filament was connected with interior being connected through lead of the electronic signal process box on being located at overhead gage, and permanent magnet of establishing in the float and waveguide filament and electronic signal process box are formed chromacoder jointly.Produce current impulse during measurement in the electronic signal process box, this current impulse is transmitted in waveguide filament, thereby outside waveguide filament, produces a circumference magnetic field; When intersect in the magnetic field that produces with the movable permanent magnet that is enclosed within on the waveguide filament as change in location when this magnetic field; Owing to can produce a strain mechanical wave pulse signal in the magnetostrictive effect, waveguide, this strain mechanical wave pulse signal is with fixing speed of sound transmission; And detected by the electronic signal process box, calculate respective.
The conduit that waveguide filament is equipped with in said centre also can be arranged on the Taper Pipe outside, and with the parallel axes of Taper Pipe, in the time of can preventing to measure superheated fluid like this for the influence of apparatus for transmitting signal.
The conduit that waveguide filament is equipped with in said centre also can be positioned over Taper Pipe inside, can reduce interference to greatest extent like this, improves signal to noise ratio (S/N ratio).
The inboard of said overhead gage and lower baffle plate is provided with anti-collision ring.
Said Taper Pipe two ends are provided with O-ring seal.
A display is equipped with at said Taper Pipe middle part.
Said Taper Pipe is by manufacturings such as metal, organic glass or glass tubes.
Good effect of the present invention is: the present invention can accurately convert the position of float in the flowmeter in Taper Pipe to signal, has greatly simplified the physical construction of flowmeter, thereby has reduced cost, enhance productivity; And permanent magnet and waveguide filament can effectively reduce interference at the middle part of flowmeter, improves the precision of product; In addition, anti-collision ring can prevent the medium leakage; Antijamming capability of the present invention is strong, can measure multiple medium and high flow rate medium.

Embodiment
As shown in Figure 1, said magnetic displacement suspended body flowmeter comprises Taper Pipe 1; The two ends of Taper Pipe 1 are provided with flange 2, and overhead gage 3 and lower baffle plate 4 are arranged in the Taper Pipe 1, and fluid media (medium) can see through two baffle plates up and down; Be provided with conduit 5 between two baffle plates, be with float 6 on the conduit 5,1 of float 6 and Taper Pipe leave annular space 7; Be provided with waveguide filament 8 in the conduit 5; Waveguide filament 8 is connected through lead with electronic signal process box 9 on being located at overhead gage 2, is provided with permanent magnet 10 in the float 6, and waveguide filament 8 is formed chromacoders with electronic signal process box 9.
The inboard of said overhead gage 3 and lower baffle plate 4 is provided with anti-collision ring 11.
Said Taper Pipe 1 two ends are provided with O-ring seal 12.
A display 13 is equipped with at said Taper Pipe 1 middle part.Display can show instantaneous velocity and integrated flow of flowmeter etc.
Said Taper Pipe 1 is by metal, organic glass or glass tube manufacturing.
During use, when medium flows into the Taper Pipe that upwards enlarges,, form differential pressure between up and down at float by the float throttling, when the lift on the float greater than the weight of float during with the differential pressure resistance, then float rises, on the contrary then decline.Rising along with float; Annular space area between its maximum outside diameter and the Taper Pipe also increases gradually; Make the differential pressure resistance that acts on the float reduce gradually; When the lift on float equals float weight and differential pressure resistance, promptly reach equilibrium of forces, and the flow value of suspended body flowmeter is just represented in float this position in Taper Pipe.At this moment; Intersect in the magnetic field that current impulse produces in the magnetic field of permanent magnet and the waveguide filament; Owing to can produce a strain mechanical wave pulse signal in the magnetostrictive effect, waveguide filament, this strain mechanical wave pulse signal is with fixing speed of sound transmission; And, calculate rate-of flow at last and be presented on the display by the detection of electronic signal process box.
