Description
Technical field
The present invention relates to flow detection technology, is related to a kind of spinner flowmeter.
Background technology
Spinner flowmeter is also known as suspended body flowmeter, is one kind of variable area formula flowmeter, expands from bottom to top at one
In vertical Taper Pipe, float is enclosed on the centre pilot bar of metal bar, and the gravity of float is born by hydrodynamic, so that float
Can in Taper Pipe freely raising and lowering.During measurement, move up and down under flow velocity and buoyancy, balanced with float weight
Afterwards, dial is passed to by magnetic coupling and indicates flow.
Spinner flowmeter is to be only second to the most broad a kind of flowmeter of differential pressure flowmeter application, especially small, micro-
Play the role of in terms of flow very important.But in measurement, the transmission change link of float position signal is more, and it passes through float
Rotary magnetic steel is coupled in the variation up and down of magnet steel, anglec of rotation change is allowed to, in combination with matching somebody with somebody for the mechanical parts such as counterweight, pointer
The position of float could be changed out by closing.Due to there is the presence of rotary magnetic steel, the stroke of float can only be in the sphere of action of magnet steel power
It is interior, metering is completed by the mechanical couplings between magnetic and magnetic, therefore traditional flowmeter can only carry out small-range measurement, its response location
Precision be also impossible to accurately, therefore measurement accuracy also will not be high.
Thus prior art could be improved and improve.
The content of the invention
In view of in place of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of spinner flowmeter, to solve
The problem of spinner survey precision of prior art is not high, and range is small.
In order to achieve the above object, this invention takes following technical scheme：
A kind of high-precision spinner flowmeter, it includes flowtube, electronics storehouse, waveguide rod, magnetic float and measurement storehouse, the waveguide
Bar is connected with the electronics storehouse, and the magnetic float is sheathed in the waveguide rod, and the magnetic float and waveguide rod are located at
In the measurement storehouse；The measurement storehouse, which is inverted, to be installed in the flowtube.
In described spinner flowmeter, the flowtube is provided with aerator.
In described spinner flowmeter, the magnetic float is inverted conical magnetic float.
In described spinner flowmeter, display screen is provided with the electronics storehouse.
In described spinner flowmeter, one end that the waveguide rod is connected with electronics storehouse bends predetermined angular.
In described spinner flowmeter, the predetermined angular is 90 degree.
Compared to prior art, spinner flowmeter provided by the invention, magnetic float is sheathed in the waveguide rod, and
The magnetic float and waveguide rod replace the center of existing metal bar by using waveguide rod in inverted measurement storehouse
Guide rod, spinner flowmeter is set to react sensitiveer, metering is more accurate, and the stroke of magnetic float is not by existing rotary magnetic steel
Magnetic force limits, and adds sensitivity and the measuring range of spinner flowmeter.Meanwhile the structure letter of spinner flowmeter of the invention
Single, cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of spinner flowmeter of the present invention.
Embodiment
The present invention provides a kind of high-precision spinner flowmeter, has taken into account the accuracy and resistant to damage work(of sensor measurement
Can, for measuring pipeline transmission medium（Such as liquid or gas）Flow, its is simple in construction, range is unrestricted, is a fill up
The blank product in market.
To make the purpose of the present invention, technical scheme and effect clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.It should be appreciated that specific embodiment described herein is not used to only to explain the present invention
Limit the present invention.
Spinner flowmeter provided by the invention includes flowtube 10, electronics storehouse 20, waveguide rod 30, the and of magnetic float 40
Storehouse 50 is measured, the measurement storehouse 50 is conical pipe, and inversion is installed in the flowtube 10, that is, measures storehouse 50 to expand from bottom to top
Big round table-like body.Certainly, the measurement storehouse can also use other geometries, and the surface of the flowtube is provided with scale
Bar, the range of the scale strip is 0-100.
The magnetic float 40 is using the small magnetic float of magnetic force, and it is sheathed in the waveguide rod 30, the flow
Pipe 10 is that stylostome, the magnetic float 40 and waveguide rod 30 are measured in storehouse 50 positioned at described, makes magnetic float 40
Fluctuated in storehouse 50 is measured.Also, the quality and profile of the magnetic float 40 can design according to range designation.
The present invention has adopted magnetostriction position survey technology, accurately and not can be measured magnetic float 40 by what range was limited
Position, so as to according to calibrating flow number.Because the stroke of magnetic float is not limited by the magnetic force of conventional rotary magnetic steel,
Therefore the range of the present technology of range ratio of the present invention is big.
The waveguide rod 30 is connected with the electronics storehouse 20, i.e. one end of waveguide rod 30 and the electronics storehouse 20
Electrical connection.When it is implemented, one end that the waveguide rod 30 is connected with electronics storehouse 20 bends a predetermined angular, i.e. waveguide rod
30 one end is stretched into electronics storehouse 20 after bending a predetermined angular, and its angle bent is preferably 90 degree（That is, it is described pre-
Angle is determined for 90 degree）, other angles are alternatively certainly.
In the present embodiment, the magnetic float 40 is inverted conical magnetic float, i.e., magnetic is floated in storehouse 50 is measured
The bottom surface of son 40 is upward, and the summit of magnetic float 40 is downward.Magnetic float 40 is arranged to inverted cone by the present invention, both sharp
In the flowing of liquid, upward balance thrust can be also produced, it is more accurate so as to make magnetic float 40 fluctuate.
Described aerator includes air blower and aeration cylinder, and described air blower is connected with aeration cylinder.
Please continue to refer to Fig. 1, the both ends of the flowtube 10 are provided with mounting flange 60, so as to by rotor

Measurement data, the present invention survey by being provided with corresponding control circuit on electronics storehouse 20, by the buoyancy of float to be converted into
Data to be measured, eliminate the complicated mechanical rotating mechanism in existing spinner flowmeter so that spinner flowmeter structure is simpler, into
This is lower.And because the spinner flowmeter of the present invention does not have magnetic rotation rotation mechanism, therefore without big magnetic force, so as to which convection current be not present
The absorption affinity of matter magnetisable material, so being not required to install magnetic filter, further save cost.
In summary, spinner flowmeter provided by the invention, magnetic float is sheathed in the waveguide rod, and the magnetic
Property float and waveguide rod positioned at it is inverted measurement storehouse in, by using waveguide rod replace existing metal bar centre pilot
Bar, and used magnetic float, makes that spinner flowmeter reaction is sensitiveer, and metering is more accurate, and the stroke of magnetic float not by
The magnetic force limitation of existing rotary magnetic steel, add the range of spinner flowmeter.Meanwhile the structure letter of spinner flowmeter of the invention
Single, cost is low.
It is understood that for those of ordinary skills, can be with technique according to the invention scheme and its hair
