Abstract
The invention discloses a waist wheel flow meter which comprises a rotating shaft, a signal board and a signal generating device. The rotating shaft is connected with a waist wheel rotor in a matched mode, and the rotating shaft and the waist wheel rotor rotate synchronously. The rotating shaft is sleeved with the signal board, the signal board rotates along with the rotating shaft, and multiple concentric holes are evenly formed in the signal board. The signal generating device is correspondingly matched with the concentric holes in the signal board. The waist wheel flow meter is simple in structure, convenient to use, high in output frequency, high in measurement accuracy and low in measurement lower limit, and greatly improves the metering performance of the waist wheel flow meter is improved.
Description
Technical field
Rotz flowmeter of the present invention, is specifically related to a kind of rotz flowmeter utilizing " grating " principle to gather flow signal.
Background technology
See Fig. 1, existing rotz flowmeter is generally made up of signal wheel 101, magnet steel 102 and magnetoelectric transducer 103, its signals collecting is that application magneto-electronic theory rotarily drives a concentric signal wheel 101 (signal wheel 101 having 2 to the magnet steel 102 installed with one heart) at waist wheel rotor, the magnetoelectricity signal that magnetoelectric transducer 103 detection signal wheel 101 sends, and then obtain uninterrupted, realize metering.
Because rotz flowmeter is a kind of volumeter, only have between two waists wheels and be full of medium it just can be made to rotate, the frequency of waist wheel rotor turns is not high, in addition signal wheel 101 only has 2 to (four) magnet steel 102, make it often to rotate and within one week, only have 4 frequency signals, when low discharge, time per unit turns less than a circle, several frequency at zero point can only be exported p.s., due to the relation of mathematics carry, there is many notes or remember phenomenon less, the metering of its lower limit low discharge is caused to there is error large, the drawback that reproducibility error is large.
Summary of the invention
The technical matters that the present invention exists to solve technique scheme, thus the rotz flowmeter that a kind of error is little, measurement range is large and measuring accuracy is high is provided.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of rotz flowmeter, it is characterized in that, described rotz flowmeter comprises:
One turning axle, described turning axle and waist are taken turns rotor engagement and are connected, and described turning axle and waist take turns rotor synchronous axial system;
One signal panels, described signal panels are on the rotary shaft sheathed, and along with turning axle rotation, on described signal panels, even distance is provided with several concentric hole;
Signal generation apparatus, described signal generation apparatus respectively with the concentric hole corresponding matching on signal panels.
In a preferred embodiment of the invention, described signal generation apparatus comprises a mounting bracket, described mounting bracket both sides are vertically provided with the first fixed head and the second fixed head respectively, described first fixed head is provided with the first photoelectric sensor, described second fixed head is provided with the second photoelectric sensor, described first photoelectric sensor and the second photoelectric sensor respectively with the concentric hole corresponding matching on signal panels.
In a preferred embodiment of the invention, described first fixed head and the second fixed head are respectively Liftable type.
By technique scheme, the invention has the beneficial effects as follows:
Structure of the present invention is simple, and easy to use, substantially increase the metering performance of rotz flowmeter, output frequency is high, and accuracy of measurement is high, and measurement lower limit is low.

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of existing rotz flowmeter;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the structural representation of signal panels.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 2 and Fig. 3, a kind of rotz flowmeter provided by the invention, it utilizes " grating " principle to gather flow signal, and can be used for mass rate and the volumetric flow rate of measuring gas, liquid medium in closed conduct, it mainly comprises turning axle 100, signal panels 200 and signal generation apparatus.
Turning axle 100, itself and waist are taken turns rotor engagement and are connected, and it can take turns rotor synchronous axial system with waist.
Signal panels 200, it is one discoid, the through hole 210 matched with turning axle 100 is offered in the middle of signal panels 200, signal panels 200 are set on turning axle 100 by through hole 210, and can rotate together along with turning axle 100, signal panels 200 are by turning axle 100 thus achieve and take turns rotor synchronous axial system with waist.
On signal panels 200, even distance offers a circle concentric hole 220, and the diameter of concentric hole 220 is specially 1mm ~ 5mm, and concentric hole 220 is convenient to match with signal generation apparatus generation voltage pulse signal.
Signal generation apparatus, it comprises a mounting bracket 300, and it is positioned at the bottom side of signal panels 200, is vertically provided with the first fixed head 310 and the second fixed head 320 in mounting bracket 300 frame both sides respectively;
First fixed head 310 and the second fixed head 320 lay respectively at the both sides of signal panels 200, first fixed head 310 is provided with the first photoelectric sensor 311 and first circuit board 312, first circuit board 312 is connected with the first photoelectric sensor 311, second fixed head 320 is provided with the second photoelectric sensor 321 and second circuit board 322, and second circuit board 322 is connected with the second photoelectric sensor 321;
First photoelectric sensor 311 and the second photoelectric sensor 321 are specifically fixed on the upper and lower of signal panels 200 concentric hole 220 circumference same position, when signal panels 200 rotate, when making the line of concentric hole 220 by the second photoelectric sensor 311 and the second photoelectric sensor 321, first photoelectric sensor 311 and the second photoelectric sensor 321 mutual induction will produce photosignal, each concentric hole 220 on such signal panels 200 can a photosignal, signal panels 200 rotate and have tens pulses outputs once enclosing, when low discharge, waist wheel rotor turns less than a circle, also several even tens pulses are had to export, substantially increase specific discharge, the frequency number of unit interval, thus improve accuracy and the repeatability of the flow measurement of rotz flowmeter lower limit, and then widen the measurement range of rotz flowmeter, improve accuracy of measurement grade.
