Description
Technical field
The utility model proposes building automatic control, heating automation control and the field of industrial automatic control electric controller for various process control links, specifically with the electric actuator of valve stroke automatic detection function.
Background technique
Electric actuator and valve are used in conjunction with, and high-low limit position and the electric actuator of valve must be matched at the scene in debug process, just can make valve complete the operation of whole stroke.Not only in the time of first use, must carry out electric actuator and mate work with the stroke of valve, and also must carry out this work when electric actuator and valve being dismantled or changed at every turn.
Traditional electric actuator need to regulate two angle stroke potentiometers in the time mating with valve simultaneously, starting point and valve stroke are set respectively, this process must just can complete after repeatedly moving adjusting coupling, and need professional workforce to carry out manual tune, not only complex operation, and accuracy rate is low, cause the waste on many manpowers and debug time.
Model utility content
The problem of mating with valve in order to solve electric actuator, the utility model provides the electric actuator with stroke self-checking function.This final controlling element, by circuit setting and control, is realized the self-inspection of electric actuator.Solve the technical problem of electric actuator self-inspection.
The scheme that the utility model technical solution problem adopts is:
Power supply is connected with cpu control circuit by current rectifying and wave filtering circuit, and function dial-up circuit, control signal Acquisition Circuit and stroke are connected with cpu control circuit respectively from detecting button circuit; Feeder loop is connected with cpu control circuit; Cpu control circuit is connected with LED display modular again after being connected with LED drive circuit; After cpu control circuit is connected with motor-drive circuit, be connected with motor again; Motor one end is connected with cpu control circuit with feedback signal Acquisition Circuit via potentiometer.
Good effect, carries out valve stroke coupling when the utility model can be realized electric actuator and mates with valve automatically, has ease for operation and precision is high, is convenient to field adjustable and maintenance, has saved commissioning staff and debug time.The suitable application as electric actuator under various working conditions.
Brief description of the drawings
Fig. 1 is the utility model control panel controlling component and circuit connection diagram
In figure, 1. power supply, 2. current rectifying and wave filtering circuit, 3. function dial-up circuit, 4. control signal Acquisition Circuit, 5. stroke is from detecting button circuit, 6. potentiometer, 7. feedback signal Acquisition Circuit, 8. feedback output circuit, 9.LED drive circuit, 10.LED display modular, 11. motor-drive circuits, 12. motors, 13.CPU control circuit.
Embodiment
According to the figure,
Power supply 1 is connected with cpu control circuit 13 by current rectifying and wave filtering circuit 2, and function dial-up circuit 3, control signal Acquisition Circuit 4 and stroke are connected with cpu control circuit respectively from detecting button circuit 5;
Feeder loop 8 is connected with cpu control circuit;
Cpu control circuit is connected with LED display modular 10 again after being connected with LED drive circuit 9;
Cpu control circuit is connected with motor 12 again after being connected with motor 11 drive circuits;
Motor one end is connected with cpu control circuit with feedback signal Acquisition Circuit 7 via potentiometer 6.
The utility model assembling parts is connected with circuit:
Motor is installed in electric actuator, is connected with driving gear at the downside of motor, driving gear is connected with T shape screw rod transmission, T shape screw mandrel is connected with potentiometer one end by feedback set square triangle, the potentiometer the other end is connected on control panel, and control panel is arranged on motor one side, is connected with motor.
Power supply is supplied with cpu control circuit by current rectifying and wave filtering circuit;
8 bit function position toggle switch are housed on control panel, are connected with cpu control circuit by 8 bit function dial-up circuit;
Control signal is connected with cpu control circuit by control signal Acquisition Circuit;
In a side of control panel, the automatic test button of stroke is installed, and is connected with cpu control circuit by the automatic test button circuit of stroke;
Cpu control circuit is again by motor-drive circuit control motor;
Straight journey potentiometer is housed on control panel, is connected with cpu control circuit by feedback signal Acquisition Circuit;
CUP control circuit is connected with feedback output circuit;
CUP control circuit is connected with LED display modular by LED drive circuit.
Working procedure of the present utility model:
Electric actuator can automatically detect the range of valve after each energising, electric actuator not only has energising automatic detection function, also can be by carrying out at any time stroke automatic detection function from test button manual control electric actuator on panel, when electric actuator is in energising situation, if need from detecting, press the red button on electric actuator circuit board, electric actuator enters automatic detected state.
When electric actuator enters after automatic detected state, the now run indicator of final controlling element flicker, final controlling element axle first stretches out and moves to limit inferior position, then indentation moves to limes superiors position, within approximately 150 seconds, rear indicator light stops flicker, the now automatic detection of final controlling element and valve body finishes, and valve body regulated with coordinating of electric actuator.Now the traffic direction of final controlling element is by control signal control.
This automatic detection function has effectively solved electric actuator because regulating valve stroke manually mates the low technical problem of operation difficulty, precision causing.
Advantage of the present utility model:
1, intellectuality: increase stroke automatic detection function, can make electric actuator automatically detect valve stroke function after each energising.
2, precision is high: automatically carry out the collection of valve high-low limit position by straight journey potentiometer, do not deposit the error that artificial debugging produces, acquisition precision is higher.
3, hommization: not only there is POST brake, only need press automatic test button as carried out stroke automatic detection function in running, can realize stroke and automatically detect, facilitate field adjustable.
4, cost is low: the utility model patent has been saved debugging difficulty and debug time greatly, without field adjustable personnel, saves debugging cost.
