Abstract

The utility model provides a flow meter turbine sensor which comprises a current pipe. The flow meter turbine sensor is characterized in that the current pipe is orderly provided with a positioning diffluent idler pulley and a screw impeller from the water input end of the current pipe to the water output end of the current pipe. The positioning diffluent guide wheel is composed of a center hub, an outer circumference, and an oriented diffluent impeller connected between the center hub and the outer circumference. The oriented diffluent impeller is used for evenly distributing and forming current in a side direction to push the screw impeller to rotate. The current pipe is positioned on the outer side part of the screw impeller and is provided with a dry reed pipe which is used for sending out measuring signals. The screw impeller is correspondingly provided with an eccentric magnetic block which drives the dry reed pipe to close twice in a rotational period. The device has the advantages of high measuring precision, small volume and simple structure.

Description

The flowmeter turbine sensor
Technical field
The utility model relates to a kind of flowmeter turbine sensor.
Background technology
Flowmeter is used very extensive in daily life and commercial production, as at the membrane type gauging table of gas metering and the mechanical type count table in the metering water meter.A kind of power generating type flow metering head (patent No. is 02246017.9) is disclosed, comprise non-magnetic conductive shell, inductive coil, impeller, p-m rotor, there is the inbound port of going out at the shell two ends, impeller and p-m rotor be in transmission connection and rotating support in the enclosure, inductive coil invests the position of the corresponding p-m rotor in the shell outside, its axle center is vertical with the axle center of p-m rotor, this device utilizes electromagnetic induction principle, air-flow or flow dynamic are changed into the rotation of impeller and p-m rotor, in inductive coil, produce its frequency and the proportional electric impulse signal of flow, though be convenient to utilize electronic technology to realize metering and intelligent management, but electric impulse signal is subjected to external interference easily, thereby can influence measuring accuracy to a certain extent.
Summary of the invention
The utility model purpose provides a kind of measuring accuracy height, volume flowmeter turbine sensor little, simple in structure.
The utility model comprises overflow pipe, it is characterized in that, described overflow pipe is equipped with location shunting guide wheel and helical runner from water intake end successively to the water side, described location shunting guide wheel by center hub, outer border and be connected in center hub and outer border between be used for evenly distribute and form the direction splitter blade that lateral stream rotates in order to the promotion helical runner, the outside portion that described overflow pipe is positioned at helical runner is provided with in order to sending the tongue tube of metering signal, the corresponding eccentric magnetic patch that orders about twice of tongue tube closure in a swing circle that is provided with on the described helical runner body.
The utility model utilizes the mating reaction of tongue tube and magnet, makes tongue tube produce the switch closure effect, thereby produces metering signal.During work, the mobile impeller of water and the rotation of being located at eccentric magnetic patch on the helical runner body, when magnetic patch when the tongue tube, order about the tongue tube closure of often opening, produce electric signal, and then reach the metering effect, and the rotating speed of helical runner and magnetic patch changes along with the size of water flow, and tongue tube correspondingly produces the different electric signal of speed.
Shunting guide wheel in location of the present utility model can make the current of water intake end flow to helical runner equably, helical runner is rotated reposefully, more accurately the reaction water stream flow.
Remarkable advantage of the present utility model is that measuring accuracy height, volume are little, simple in structure.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is that the A of guide wheel is shunted to view in the location among Fig. 1.
Fig. 3 is a location shunting guide wheel working state schematic representation.
Embodiment
The utility model comprises overflow pipe 1, it is characterized in that, described overflow pipe 1 is equipped with location shunting guide wheel 4 and helical runner 5 from water intake end 2 successively to water side 3, described location shunting guide wheel is by center hub 6, outer border 7 and be connected in center hub and outer border between be used for evenly distribute and form lateral stream in order to the direction splitter blade 8 that promotes the helical runner rotation, the outside portion that described overflow pipe 4 is positioned at helical runner is provided with in order to the tongue tube 9 that sends metering signal, the corresponding eccentric magnetic patch 10 that orders about twice of tongue tube closure in a swing circle that is provided with on the described helical runner body.
In order to prevent that current from producing the reverse flow phenomenon because of stopping up or impacting fortuitous event such as excessive, so that promote the helical runner retrograde rotation, influence measuring accuracy, be positioned at the place, water side in the above-mentioned overflow pipe and be provided with reverse water Flow Control ratch 11, described reverse water Flow Control ratch wheel hub perimembranous is provided with the guide vane 12 at the reverse flow direction of guiding middle part, shown in the part of the reverse water Flow Control ratch among Fig. 1, reverse flow direction wheel hub middle part can not produce reverse impetus to helical runner.
When the utility model uses, with this device serial connection in water stream channel, current evenly flow to helical runner through location shunting guide wheel, drive helical runner and place the eccentric magnetic patch in the helical runner body to rotate, in a swing circle, when magnetic patch when the clarinet, drive that often to open clarinet closed and produce electric signal, electric signal is converted to continuous data after treatment.
The utility model is the measuring accuracy height when water flow measurement, and volume is small and exquisite, simple in structure simultaneously.
