Under the solenoid 2108 no power state of switching valve 21, motor drives piston 6, and when the long-pending increase of piston endosome, in piston, pressure is less than ambient pressure, forms negative pressure；Now, check valve B, check valve C are closed, and check valve A, check valve E are in open mode.This negative pressure is through upper liquid mouth 2006, it is delivered to switch the switching outlet B of valve, owing to switching the solenoid no power of valve, piston make elastomer act under action of reset spring before valve seat, valve C is made to be closed, and valve D is in open mode, valve pocket B and valve pocket A keeps through, and negative pressure is thus delivered to valve pocket A.Be equivalent to the pressure in the detergent A box 4 of atmospheric pressure more than the pressure in valve pocket A, detergent in detergent A box flows into valve pocket A through check valve A, the parameter designing of back-moving spring ensures that it be enough to the valve C that makes the pressure of elastomer that the atmospheric pressure overcoming detergent B box 9 and the difference of negative pressure in valve pocket B cause and remains off, thus the detergent in detergent B box cannot flow into valve pocket B.When the long-pending reduction of piston endosome, in piston, pressure is more than ambient pressure；Now, check valve E closes, and check valve B opens.Liquid in piston is extruded, and liquid flows into main channel by the negative pressure mouth of venturi negative pressure generator, finally flows into washing tube.Once, the detergent amount extracted out from detergent A box is certain to piston reciprocating, only need to control the number of times of piston reciprocating, can control the injected volume of detergent.When the detergent injected volume of metering reaches target setting value, closure piston motor, i.e. stop detergent A suction and throw in.Open water intaking valve 1, perform aforementioned flushing action, the detergent A in the stream including switching valve and piston can be rinsed well after continuing for some time.
Three, putting detergent B
Under the solenoid "on" position of switching valve, motor drives piston 6, and when the long-pending increase of piston endosome, in piston, pressure is less than ambient pressure, forms negative pressure；Now, check valve B is closed, and check valve E is in open mode.This negative pressure is through upper liquid mouth, it is delivered to switch the switching outlet B of valve, solenoid energising due to switching valve, piston overcomes the active force of back-moving spring to make elastomer act on rear valve base under electromagnetic attraction effect, and valve C opens, and valve D closes, the passage of valve pocket B and valve pocket A is cut off, therefore negative pressure can only be delivered to valve pocket B, and the pressure be equivalent in the detergent B box of atmospheric pressure flows into valve pocket B more than the pressure in valve pocket B, the detergent in detergent B box.When the long-pending reduction of piston endosome, in piston, pressure is more than ambient pressure；Now, check valve E closes, and check valve B opens.Liquid in piston is extruded, and liquid flows into main channel by the negative pressure mouth of venturi negative pressure generator, finally flows into washing tube.Once, the detergent amount examination being drawn out of detergent box B is certain, only need to control the number of times of piston reciprocating, can control the injected volume of detergent for piston reciprocating.When the detergent injected volume of metering reaches target setting value, close motor and drive piston, i.e. stop detergent B suction and throw in.
In stream, detergent B's rinses like the flushing with above-mentioned detergent A.
