Description
The utility model is a kind of electromagnetism water valve with new Design of Mechanical Structure and automatic control circuit.Be mainly used in family, hotel and some need the public place of water.
Tradition electromagnetism water valve mainly contains two classes: a class is directly to drive the irony valve core with conical surface by the electromagnetic force that electromagnetic coil produced to stop up osculum; Another kind of is to drive the cylindricality rotation valve core that the water port is arranged by stepper motor to open and close osculum.The major defect of tradition electromagnetism water valve is that volume and weight is big, cost is high, function singleness, use are installed trouble.This enters family just for the electromagnetism water valve and extensive use brings difficulty.
The purpose of this utility model is to provide a kind of functional price than high and civilian electromagnetism water valve easy to use.
Automatic control electromagnetism water valve described in the utility model is to utilize hydraulic pressure in the water pipe, goes to control the switching of water valve branch road flexible pipe with electromagnetic coil with very little electromagnetic energy, handles the function that water valve opens and closes to reach.
The utility model compares with existing traditional electromagnetism water valve, has the following advantages:
1, volume is little, and is in light weight.
2, power consumptive province, cost are low.
3, Perfect in shape and function, installation, easy to use, automaticity is high.
Below in conjunction with accompanying drawing automatic control electromagnetism water valve described in the utility model is described further.

Embodiment:
Accompanying drawing (1) has provided the structure principle chart of the utility model mechanical part.
With reference to accompanying drawing (1): constituent element be water valve housing (1) with main flow path and diverter branch, branch road flexible pipe (2), armature (3) electromagnetic coil (4),, elastic strip (5), elastic bellows (6), connecting rod (7), osculum (8), rubber bulb stopper (9).
The machinery action process: in electromagnetic coil (4) electric current is arranged, under the effect of electromagnetic force, armature (3) overcomes the restraining force of elastic strip (5), unclamps the branch road flexible pipe (2) of original clamping.Because P0 point hydraulic pressure is greater than the P1 point, current flow into elastic bellows (6) by branch road flexible pipe (2) and make its tympanites, drivening rod (7) jack-up bulb stopper (7).At this moment, make electromagnetic coil (4) dead electricity by control circuit (seeing accompanying drawing (3)), armature (3) compresses branch road flexible pipe (2) again and interrupts current under the restraining force of elastic strip (5), to keep the hydraulic pressure in the elastic bellows (6).This moment, water valve was in open mode, and water flows out water valve by osculum (8).
Switch on once more when electromagnetic coil (4), another opens branch road flexible pipe (2).Because this moment, water valve was in open mode, there are flowing out.So P0 point hydraulic pressure is less than the P1 point.Elastic bellows (6) shrinks under himself elastic restoring force effect, and water flows to the P0 point by the P point through branch road flexible pipe (2).When elastic bellows (6) contraction returned to original state, control circuit made electromagnetic coil (4) dead electricity, and armature (3) compresses branch road flexible pipe (2) bulb stopper again because of losing support force upwards under elastic strip (5) effect, fallen by water impact.The hydraulic pressure that P0 is ordered in the water valve raises gradually, and last bulb stopper (9) is blocked anhydrous outflow in osculum (8) water valve.Thereby finish the overall process of a water valve switching.
Accompanying drawing (2) and (3) have provided principle of work and power skeleton diagram of the present utility model and circuit theory diagrams.
With reference to accompanying drawing (2) and (3), this circuit is a pulse generating circuit, by six part picture groups:
(1) sensing circuit: form by triode BG3, potentiometer W, resistance R b3, Rc3, photoresistor (cds).
(2) trigger circuit: form by capacitor C 3, resistance R 6.
(3) monostable circuit: by three utmost point BG1, BG2, capacitor C 1, C2, C3,, resistance R b1, Rb2, Rc1, Rc2, R5 form.
(4) see-saw circuit: form by triode BG4, resistance R c4, RE4.
(5) actuating circuit: form by bidirectional triode thyristor SCR, electromagnetic coil L.
(6) power circuit: by transformer B, triode BG0, diode D1, D2, D3, D4, voltage-stabiliser tube D5, capacitor C 0, resistance R 0, R1, R2, R3, R4, REc form.
Under day ordinary ray irradiation, photoresistor CDS internal resistance is very little, and VDC+E acts on the BG3 base stage by (A), the output of (B) two ends through W, Rb3 dividing potential drop, makes the low potential of BG3 conducting and collector electrode.The input of trigger circuit input end (C) some no signal.This moment, monostable circuit was not overturn, keep BG to be high petential by (E) point, BG2 conducting (D) point acts on the BG4 base stage for the initial steady state of low potential (E) some high petential, making its conducting and collector electrode (F) point is low potential, bidirectional triode thyristor SCR control end triggerless pulse input, SCR is in being in off-state, no current in the electromagnetic coil L, and armature is failure to actuate.
As object process on photoresistor CDS, in the △ T time, block the light that shines on the CDS, the resistance of CDS is changed from small to big, because the resistance hypotensive effect of CDS makes the BG3 base potential again from high to low.So just produced a positive pulse at (C) point.This pulse acts on monostable circuit input end (D) point through C3, acts on the BG1 base stage through capacitor C 2, and its current potential is uprised by low, and BG is by by becoming conducting, and collector electrode (E point) current potential is by high step-down, and the BG2 conducting becomes and ends.The potential change of (E point) acts on the BG4 base stage, BG4 is become by conducting to be ended, its collector potential is uprised by low, act on (F) point, trigger two-way controlled SCR and make it conducting, exchange 220 volts of voltages and act on electromagnetic coil L5,6 terminals, coil electricity, armature (3) action through transformer B, bidirectional triode thyristor SCR.
After the triggering positive pulse in the input of (C) point disappeared, because C1 is charged by voltage+Ec in the BG1 side in advance, so BG2 one ends, BG1 base stage moment ground was+Ec that the on state of BG1 is also being kept after defeated trigger impulse finishes.But the BG2 base potential rises to initial value again after capacitor C 1 is by BG1, power supply+E, the discharge of Rb2 loop, BG2 is conducting once more, and trigger circuit return to reset condition.So, the BG1 collector electrode can obtain by parameters C 1, Rb2 ,+the pulse ts of the certain width of Ec, E size decision.Ts is converted to expansion (contraction) attitude needed time when elastic bellows (6) by shrinking (expansion) attitude.
Ts can be determined by following formula:
ts＝Tln（ (E)/(E
C) －1）
Wherein: T=Rb2 * C1.
