Description

A kind of spinner-type flowmeter
Technical field
The utility model relates to flow detection technology, relates to a kind of spinner-type flowmeter.
Background technology
Spinner-type flowmeter claims again suspended body flowmeter, be a kind of of variable area formula flowmeter, in a vertical Taper Pipe expanding from bottom to top, float is enclosed within on the centre pilot bar of metal bar, the gravity of float is born by hydrodynamic, thereby makes float in Taper Pipe, freely rise and to decline.During measurement, under flow velocity and buoyancy, move up and down, after float weight balance, by magnetic coupling, pass to index dial indication flow.
Spinner-type flowmeter is to be only second to the class flowmeter that differential pressure flowmeter range of application is the broadest, especially aspect little, micrometeor, has very important effect.But when measuring, the transmission of float position signal variation link is many, and rotary magnetic steel is coupled in its change up and down by float magnet steel, makes it the anglec of rotation and changes, the position that could change out float in conjunction with the cooperation of the mechanical parts such as counterweight, pointer simultaneously.Owing to there being the existence of rotary magnetic steel, the stroke of float can only complete metering by the mechanical couplings between magnetic and magnetic in the reach of magnet steel power, therefore traditional flowmeter can only carry out small-range measurement, the precision of its response location also can not be accurate, therefore measuring accuracy also can be high.
Thereby prior art need to improve.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of spinner-type flowmeter, not high to solve the spinner survey precision of prior art, the problem that range is little.
In order to achieve the above object, the utility model has been taked following technical scheme:
A kind of spinner-type flowmeter, it comprises flowtube, electronics storehouse, waveguide rod, magnetic float and measurement storehouse, described waveguide rod is connected with described electronics storehouse, and described magnetic float is sheathed in described waveguide rod, and described magnetic float and waveguide rod are arranged in described measurement storehouse; Described measurement storehouse is inverted and is installed in described flowtube.
In described spinner-type flowmeter, the two ends of described flowtube are provided with mounting flange.
In described spinner-type flowmeter, described magnetic float is inverted conical magnetic float.
In described spinner-type flowmeter, described electronics is provided with display screen on storehouse.
In described spinner-type flowmeter, the crooked predetermined angular in one end that described waveguide rod is connected with electronics storehouse.
In described spinner-type flowmeter, described predetermined angular is 90 degree.
Compared to prior art, the spinner-type flowmeter that the utility model provides, magnetic float is sheathed in described waveguide rod, and described magnetic float and waveguide rod are arranged in inverted measurement storehouse, by using waveguide rod to replace the centre pilot bar of existing metal bar, make spinner-type flowmeter reaction sensitiveer, measure more accurate, and the stroke of magnetic float do not limit by the magnetic force of existing rotary magnetic steel, increased the sensitivity of spinner-type flowmeter and measured range.Meanwhile, spinner-type flowmeter of the present utility model simple in structure, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spinner-type flowmeter.
Embodiment
The utility model provides a kind of spinner-type flowmeter, accuracy and the anti-damageability function of sensor measurement have been taken into account, for the flow of measuring channel transmission medium (as liquid or gas), it is simple in structure, range is not limited, is a blank product of filling up market.
For making the purpose of this utility model, technical scheme and effect clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The spinner-type flowmeter that the utility model provides comprises flowtube 10, electronics storehouse 20, waveguide rod 30, magnetic float 40 and measures storehouse 50, described measurement storehouse 50 is tapered tube, inversion is installed in described flowtube 10, measures the round table-like body of storehouse 50 for expanding from bottom to top.Certainly, this measurement storehouse also can adopt other geometric configuration.
Described magnetic float 40 adopts the small magnetic float of magnetic force, and it is sheathed in described waveguide rod 30, and described flowtube 10 is stylostome, and described magnetic float 40 and waveguide rod 30 are arranged in described measurement storehouse 50, and magnetic float 40 is fluctuated in measuring storehouse 50.And the quality of described magnetic float 40 and profile can design according to range designation.
The utility model has been adopted magnetostriction position survey technology, can be accurately and the position of measuring magnetic float 40 that is not subject to limit of range, thus can be according to calibrating flow number.Because the stroke of magnetic float is not limited by the magnetic force of rotary magnetic steel in the past, therefore the range of the present technology of range ratio of the present utility model is large.
Described waveguide rod 30 is connected with described electronics storehouse 20, and one end of waveguide rod 30 is electrically connected to described electronics storehouse 20.During concrete enforcement, the crooked predetermined angular in one end that described waveguide rod 30 is connected with electronics storehouse 20, stretches in electronics storehouse 20 after the crooked predetermined angular in one end of waveguide rod 30, and (its crooked angle is preferably 90 degree, described predetermined angular is 90 degree), certainly also can be other angle.
In the present embodiment, described magnetic float 40 is inverted conical magnetic float, and in measuring storehouse 50, the bottom surface of magnetic float 40 makes progress, and the summit of magnetic float 40 is downward.The utility model is set to inverted taper shape by magnetic float 40, has both been beneficial to flowing of liquid, also can produce balanced thrust force upwards, thereby it is more accurate to make magnetic float 40 fluctuate.
Please continue to refer to Fig. 1, the two ends of described flowtube 10 are provided with mounting flange 60, thereby spinner-type flowmeter can be arranged on object under test, as are arranged on testing liquid haulage vehicle.
Further in embodiment, on described electronics storehouse 20, display screen can be set, this display screen is display measurement data intuitively, the utility model by being provided with corresponding control circuit on electronics storehouse 20, the buoyancy of float is converted into measurement data, removed the complicated mechanical rotating mechanism in existing spinner-type flowmeter from, made spinner-type flowmeter structure simpler, cost is lower.And because spinner-type flowmeter of the present utility model does not have magnetic rotation mechanism, therefore there is no large magnetic force, thus there is not the absorption affinity to liquid magnetisable material, so do not need to install magnetic filter, further provide cost savings.
In sum, the spinner-type flowmeter that the utility model provides, magnetic float is sheathed in described waveguide rod, and described magnetic float and waveguide rod are arranged in inverted measurement storehouse, by using waveguide rod to replace the centre pilot bar of existing metal bar, and used magnetic float, make spinner-type flowmeter reaction sensitiveer, measure more accurately, and the stroke of magnetic float do not limit by the magnetic force of existing rotary magnetic steel, increased the range of spinner-type flowmeter.Meanwhile, spinner-type flowmeter of the present utility model simple in structure, cost is low.
Be understandable that; for those of ordinary skills; can be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, and all these changes or replacement all should belong to the protection domain of the appended claim of the utility model.
