Description
Technical field
The present invention relates to flow detection technology, it is related to a kind of spinner flowmeter.
Background technology
Spinner flowmeter, also known as suspended body flowmeter, is one kind of variable area formula flowmeter, at one from bottom to top
In the vertical Taper Pipe for expanding, float is enclosed within the centre pilot bar of metal bar, and the gravity of float is moved by liquid
Power is born so that float can in Taper Pipe freely raising and lowering.During measurement, in flow velocity and buoyancy
Effect is lower to move up and down, and after float weight balance, passes to dial by magnetic coupling and indicates flow.
Spinner flowmeter is to be only second to the most broad class flowmeter of differential pressure flowmeter range of application, is especially existed
Small, micrometeor aspect plays the role of very important.But in measurement, the transmission change of float position signal
Link is more, and rotary magnetic steel is coupled in its variation up and down for passing through float magnet steel, is allowed to anglec of rotation change, together
When could change out the position of float with reference to the cooperation of the mechanical parts such as counterweight, pointer.Due to there is rotary magnetic steel
Presence, the stroke of float can only be complete by the mechanical couplings between magnetic and magnetic in the sphere of action of magnet steel power
Into metering, therefore traditional flowmeter can only carry out small-range measurement, and the precision of its response location is also impossible to essence
Really, thus certainty of measurement also will not be high.
Thus prior art could be improved and improve.
The content of the invention
In view of above-mentioned the deficiencies in the prior art part, it is an object of the invention to provide a kind of spinner flowmeter,
It is not high with the spinner survey precision for solving prior art, the small problem of range.
In order to achieve the above object, this invention takes following technical scheme：
A kind of high accuracy spinner flowmeter, it includes flowtube, electronics storehouse, waveguide rod, magnetic float and survey
Amount storehouse, the waveguide rod 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 in the measurement storehouse；It is inverted and is installed in the flowtube in the measurement storehouse
In.
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 bending predetermined angular that the waveguide rod is connected with electronics storehouse.
In described spinner flowmeter, the predetermined angular is 90 degree.
Compared to the spinner flowmeter that prior art, the present invention are provided, magnetic float is sheathed on the waveguide
On bar, and the magnetic float and waveguide rod are located in inverted measurement storehouse, replace existing by using waveguide rod
The centre pilot bar of some metal bars, makes spinner flowmeter react sensitiveer, and metering is more accurate, and magnetic
The stroke of property float is not limited by the magnetic force of existing rotary magnetic steel, increased the sensitivity and survey of spinner flowmeter
Amount range.Meanwhile, the simple structure of spinner flowmeter of the invention, low cost.
Brief description of the drawings
Fig. 1 is the structural representation of spinner flowmeter of the present invention.
Specific embodiment
The present invention provides a kind of high accuracy spinner flowmeter, has taken into account the accuracy and resistant to damage of sensor measurement
Sexual function, the flow for measuring pipeline transmission medium (such as liquid or gas), its simple structure, range
It is unrestricted, it is a blank product for filling up market.
To make the purpose of the present invention, technical scheme and effect clearer, clear and definite, develop simultaneously referring to the drawings
The present invention is described in more detail for embodiment.It should be appreciated that specific embodiment described herein is only used to
The present invention is explained, is not intended to limit the present invention.
The spinner flowmeter that the present invention is provided includes that flowtube 10, electronics storehouse 20, waveguide rod 30, magnetic are floated
Son 40 and measurement storehouse 50, the measurement storehouse 50 is conical pipe, and inversion is installed in the flowtube 10,
I.e. measurement storehouse 50 is the round table-like body for expanding from bottom to top.Certainly, the measurement storehouse can also use other geometry
Shape, the surface of the flowtube is provided with scale strip, and the range of the scale strip is 0-100.
Using the small magnetic float of magnetic force, it is sheathed in the waveguide rod 30 magnetic float 40,
The flowtube 10 is stylostome, and the magnetic float 40 and waveguide rod 30 are located at the measurement storehouse 50
In, magnetic float 40 is fluctuated in storehouse 50 is measured.Also, the quality of the magnetic float 40
Can be designed according to range designation with profile.
The present invention has adopted magnetostriction position survey technology, accurately and can not measured magnetic by what range was limited
The position of float 40, flow number is calibrated so as to foundation.Because the stroke of magnetic float was not revolved in the past
Turn the magnetic force limitation of magnet steel, therefore the range of the present technology of range ratio of the 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 electrically connects.During specific implementation, one end bending one that the waveguide rod 30 is connected with electronics storehouse 20
Stretched into after one predetermined angular of one end bending of predetermined angular, i.e. waveguide rod 30 in electronics storehouse 20, it bends
Angle be preferably 90 degree (that is, described predetermined angulars be 90 degree), other angles are alternatively certainly.
In the present embodiment, the magnetic float 40 is inverted conical magnetic float, i.e., in measurement storehouse 50
Upwards, the summit of magnetic float 40 is downward for the bottom surface of middle magnetic float 40.The present invention sets magnetic float 40
Inverted cone is set to, both beneficial to the flowing of liquid, upward balance thrust can be also produced, so as to make
Magnetic float 40 fluctuates more accurate.
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 two ends of the flowtube 10 are provided with mounting flange 60 such that it is able to
Spinner flowmeter is arranged on object under test, is such as arranged on testing liquid haulage vehicle.
In further embodiment, display screen can be set on the electronics storehouse 20, the display screen can be directly perceived
Display measurement data, the present invention by being provided with electronics storehouse 20 corresponding control circuit, by float
Buoyancy be converted into measurement data, eliminate the complicated mechanical rotating mechanism in existing spinner flowmeter,
So that spinner flowmeter structure is simpler, cost is lower.And because spinner flowmeter of the invention does not have magnetic
Rotating mechanism, therefore without big magnetic force, so that in the absence of the absorption affinity to liquid magnetisable material, so be not required to
Installing magnetic filter, further saves cost.
In sum, the spinner flowmeter that the present invention is provided, magnetic float is sheathed in the waveguide rod,
And the magnetic float and waveguide rod are located in inverted measurement storehouse, and existing gold is replaced by using waveguide rod
Belong to the centre pilot bar of bar, and used magnetic float, spinner flowmeter is reacted sensitiveer, metering is more
Accurately, and the stroke of magnetic float is not limited by the magnetic force of existing rotary magnetic steel, increased spinner flowmeter
Range.Meanwhile, the simple structure of spinner flowmeter of the invention, low cost.
It is understood that for those of ordinary skills, can be with technology according to the present invention scheme
And its inventive concept is subject to equivalent or change, and all these changes or replacement should all belong to institute of the present invention
Attached scope of the claims.
