Embodiment:
The present embodiment: as shown in Figure 1, 2, 3, magnet steel 2 is arranged on the feedback rod 1 in a kind of valve position sensor, including feedback rod 1,
Valve in 2 induction range of magnet steel reaches a position setting upper limit Hall switch 3, and the valve in induction range closes in place
Lower limit Hall switch 4 is arranged in position, and the upper limit Hall switch 3 and lower limit Hall switch 4 generate under the magnetic action through magnet steel 2
Potential difference after amplifier amplifies trigger switch circuit is connected.
Since using magnet steel is arranged on the feedback rod, the valve in the magnet steel induction range is reached in a position setting
Hall switch is limited, the valve in induction range closes position in place and lower limit Hall switch is arranged, and the upper limit Hall switch is under
Limiting potential difference of the Hall switch through generating under the magnetic action of magnet steel trigger switch after amplifier amplifies is connected circuit, due to
Valve position sensor is using magnetic switch --- bipolarity Hall switch is set as the conversion of valve event position signal to electric signal
2 bipolarity Hall switch that are standby, integrating on signal processing circuit board are located at the position of " valve reaches position " and " valve close
At position in place ", after valve position sensor is fixed to above diaphragm valve, valve switch related connecting column movement, feedback when acting
The magnet steel on bar top also moves, and when the valve is open, feedback rod is driven to move up, when valve reaches, feedback rod top
Magnet steel it is close and rest at the bipolarity Hall switch of " valve reaches position ", generate electricity so as to cause bipolarity Hall switch
Potential difference is amplified through the amplifier in signal processing circuit board integrated circuit, and valve body is reached a state and changed by trigger circuit conducting
Controller is sent at electric signal.When the valve is closed, feedback rod is driven to move down, magnet steel leaves the bipolarity of " valve reaches position "
It is 0 so as to cause the potential difference that bipolarity Hall switch generates, disconnecting circuit, valve reaches a signal and loses near Hall switch
It loses.It at the bipolarity Hall switch that magnet steel moves down into " valve closes in place " with feedback rod and stops, at this moment bipolarity Hall
Switch generates potential difference in magnetic action, after amplifier amplifies, trigger circuit conducting, valve close in place signal just by success
It is converted into electric signal and issues controller, therefore, this sensor is suitable for controlling opening of valve or adjusts feedback switch position.
The Hall switch is bipolarity Hall switch.
Due to using the Hall switch for bipolarity Hall switch, valve position sensor uses magnetic switch --- bipolarity
Conversion equipment of the Hall switch as valve event position signal to electric signal, bipolarity Hall switch are usually that Hall is applied to imitate
The semiconductor answered.Hall wafer there are four leading-out terminal, wherein two be Hall element bias current input terminal,
Another two be Hall voltage output end.Bias current is passed at wafer both ends, and is applied in the vertical direction of thin slice
Uniform magnetic field will generate potential difference then on the direction perpendicular to electric current and magnetic field, be Hall voltage, and through integrated circuit
In amplifier amplification, the voltage amplification can be made to being enough to export stronger signal.Bipolarity Hall switch is opened than common mechanical
Close simple structure, small in size, light-weight, small power consumption, speed height, long working life;And compared with electronic switch, it has anti-again

Now valve event signal is changed, is extracted conducive to signal, magnet steel is fixed on valve connection top end, follows connecting column dynamic
Make.In valve opening or closing process, magnet can be rested on the position of corresponding adjustable position inductor, to touch
The movement of adjustable position inductor is sent out, and electric signal is issued into controller.
Corresponding position indicator 6 is triggered after the upper limit Hall switch 3 and lower limit Hall switch 4 are sensed respectively.
Due to triggering corresponding position instruction respectively after using the upper limit Hall switch and lower limit Hall switch sensed
Lamp, since the upper and lower position indicator light (two faces) that signal processing circuit board integrates is made of LED light emitting diode, when " valve is opened
When bipolarity Hall switch in place " is influenced circuit conducting by magnet steel, two faces, one light emitting diode sends out a warning, when " valve pass is arrived
When the bipolarity Hall switch of position " is influenced circuit conducting by magnet steel, another light emitting diode in two faces gives a green light.Two faces before and after use
The upper and lower position indicator light of LED light emitting diode facilitates site operation early period under the premise of no normal controller is run, existing
Field instruction valve opening adjusts feedback switch position, and the two face upper and lower positions Jun You refer to before and after upper and lower position indicator light (two faces)
Show lamp, in place, two-sided upper indicator light shows red light to valve "ON", conversely, showing green light, has two on signal processing circuit board
Face upper and lower position indicator light, it may be determined that polarity and feedback lamp instruction.
The valve position sensor junction is sealed through O-ring 7.
Due to being sealed using the valve position sensor junction through O-ring, due to the composition of the parts such as O-ring, O-ring master
It is used for the sealing of equipment each section junction, has prevented water from entering equipment, so that equipment normal operation is influenced, with waterproof
Feature.
Due to being used for feedback device being fixed on valve body using pedestal, fixed function is played, guarantees that device and valve are steady
Fixed effectively connection, shield (shell) are used for water proof and dust proof, guarantee that equipment operates normally environment, and therefore, this sensor has knot
Structure is compact, light-weight: can be mounted on extremely limited space, extremely be applicable in micromodule equipment, long working life: do not adopted cunning
Dynamic element is not in the metal fatigue phenomenon to degrade by metal, it is ensured that actually limitless mechanical service life and precision
It is high.
