Connect after Ql and S1, the alternating current 220V voltage between L3 end and N holds after C1 step-down, VS voltage stabilizing, VD rectification and C2 filtering, for detection control circuit provides 12V(Vcc) about DC voltage.Now due to anhydrous in water pot, its internal pressure is lower, the moving contact of pressure gauge Q2 (in) connects with lower limit contact (low), make 2 pin of IC, 3 pin output high level that 6 pin are electronegative potential (lower than Vcc/3), IC, VL2 lights, VT is triggered and conducting, and KM is energized adhesive, and its normally opened contact is connected, diving pump motor M is energized work, starts to draw water in water pot.
Along with the continuous rising of water level in water pot, in tank, pressure also increases gradually, moving contact and the lower limit contact of pressure gauge Q2 disconnect, now because the 6 pin voltages of series connection bleeder circuit to IC of R2, R3 composition carry out clamper control, make it lower than 2Vcc/3,3 pin of IC still export high level, and diving pump motor M continues to draw water in water pot.When in water pot water level raise, make pressure in tank reach pressure gauge Q2 set pressure upper limit time, the moving contact of Q2 and upper limit contacting, 6 pin of IC are made to become noble potential (higher than 2Vcc/3), circuit upset in IC, 3 pin output low levels, make VL2 extinguish, VL1 lights, VT ends, and KM discharges, and diving pump motor M power-off quits work.
User constantly can make water level decreasing in water pot again with water, and when the pressure upper limit that pressure in water pot sets lower than Q2, moving contact and the upper limit contact of Q2 disconnect, but because the 2 pin voltages of IC are still higher than the 3 pin still output low level of V, J3, IC.Until the falling pressure that in water pot, Pressure Drop sets to Q2, the moving contact of Q2 and lower limit contacting, when 2 pin of IC become electronegative potential (lower than Vcc/3), in IC, circuit just overturns, and 3 pin export high level, make VT conducting, KM adhesive, M is energized work, starts again to draw water in water pot.
