The course of work of these two parts is such:
At first, introduce liquid liquid level trigger tube;
The liquid level trigger tube can just be put in application, also can put upside down.The liquid level trigger tube E that is installed in the lower limit place in automatic, manual control of liquid level and alarm is for putting upside down, and F is for just putting, and trigger tube E and F are on same horizontal line, and the liquid level trigger tube G that is installed in upper limit place is for putting upside down.Owing in the trigger tube gas is housed, under the effect of liquid buoyancy or trigger tube self gravitation, movable post 3 movable plates 4 trigger sheet 5 can produce relative motion with stator 1 together.Trigger sheet 5 and trigger electrode and pick out end 2 and just be path in a, b two ends when contact when liquid buoyancy or the effect of trigger tube self gravitation make, do not pick out when holding 2 to contact a, b just for opening circuit with trigger electrode when buoyancy or the effect of trigger tube self gravitation make triggering sheet 5.
Secondly, the introduce liquid liquid level is automatic, manually control and alarm circuit;
Automatic function: when beginning not have liquid, it is path that the liquid level trigger tube E that is putting upside down at lower limit place does not have buoyancy.It is path that the liquid level trigger tube G that is putting upside down at upper limit place does not have buoyancy.After the energising, by semifixed resistor R

3Losing forward bias voltage is ended by saturated becoming.The back circuit quits work because of stopping power supply, and circuit stops feed flow, and work shows light emitting diode VD
3Stop luminous making and stop the feed flow demonstration.When the liquid level in the flow container descended some owing to a variety of causes after, the liquid level trigger tube G that is putting upside down at upper limit place loss of buoyance again became path by open circuit.BG
3Obtain forward bias voltage by by becoming saturatedly, the back circuit gets electric, but because when beginning electricly, monostable circuit IC
2-1, bistable circuit IC
2-2Output terminal all be low level, and liquid level trigger tube E keeps open circuit, so circuit continue to keep stopping the feed flow state.When liquid level dropped to bottom limit level always, the trigger tube E loss of buoyance of putting upside down at lower limit place became path by open circuit.BG
1Obtain forward bias voltage by saturated by becoming, circuit will repeat above process.
Manual function:, just can give bistable circuit IC as long as press trigger button AN again and again
2-2Trigger end CP
2End input positive one by one by R
5The trigger pulse of restriction makes bistable circuit IC
2-2Wheel doubles commentaries on classics, Q
2The end wheel turns over the high and low level of output, thereby the pass of control VS, disconnected makes the original liquid level Control work state of circuit do once to change.Liquid level is manually controlled like this.The liquid level trigger tube F of just putting is installed in the bottom limit level place, with the trigger tube E that is putting upside down at lower limit place on same horizontal line.When liquid level to down in limited time, the trigger tube F loss of buoyance of just putting becomes open circuit, manual function is stolen to go out circuit, manual function at this moment is invalid, circuit will continue to keep the water inlet duty of automatic function under controlling.Be lower than upward in limited time when liquid level is higher than lower limit, trigger tube F obtains buoyancy and becomes path, the manual function access circuit, and manual function is effective.When liquid level is prescribed a time limit to last, because BG
3End, the back circuit is stopped power supply, thereby manual function at this moment is also invalid, if at this moment will can not continue to go up liquid by the manual function circuit.VD
2Be for preventing that manual function from setting up the influence of charging circuit.
Automatic function can work independently in the circuit, and manual function also can work independently, but automatic function and manual function cooperating also.IC
2-1, IC
2-2Belong to an ic chip together
2Two d type flip flops.
