The control circuit consists of capacitance step-down rectifier circuit,electro connecting pressure gauge,555 trigger circuit,SCR control circuit. Capacitance step-down rectifier circuit provides DC voltage for the whole control circuit.When there is no water in the water control, the electro connecting pressure gauge P's internal pressure is low,the movable contact l in table and lower contact 3 are closed,so that IC (555) ② pin is low level,the corresponding 555 is set,the high level output by 3-pin makes the semiconductor control rectifier SCR trigger conduct,CJ pulls in, pump D fetches water inside the water control,the pressure in the pressure gauge increases.
