The working principle of the utility model is as follows:

1. the water inlet 14 of the body is opened, the valve B and the valve C are in an opening state at the moment, the water outlet of the body B and the water outlet of the body C simultaneously discharge water, the water outlet pipe of the valve C is provided with a water replenishing water outlet 20 of the valve C and is connected with a water replenishing water inlet 26 of the water stopping cup B, and the water stopping cup A is communicated with the water stopping cup B, so that the buoy A and the buoy B ascend, the air release hole 3 of the pressure release valve on the valve A is closed, the valve B is closed, the valve C continues to discharge water at the moment, water which is excessive after the water stopping cup A and the water stopping cup B are full flows into the water stopping cup C from the flow control hole 37, at the moment, the buoy C and the buoy D ascend, the valve C is closed, and the air release hole 29 of the pressure release valve B is closed.

2. According to the technical scheme, the air pressure button 1 is pressed, air pressure passes through the one-way valve 2 through the air pressure pipe 25A and passes through the air inlet 32A, the air leakage hole 3 is closed, the pump membrane 4 pushes the push rod 5 to move forwards under the action of the air pressure, the sealing ring 7 is opened, and the pressure is released through the pressure release hole 8. The water of A valve upper cover upper segment passes through pressure release hole 8, discharges from pressure release delivery port 24, because A valve upper cover pressure release hole pressure release, the pressure of A valve upper segment is greater than the pressure of hypomere this moment, and water stop pad 11 is opened under hydraulic effect, and the A valve is opened, and A body delivery port goes out water.

3. Meanwhile, the air pressure also passes through the air pressure pipe 25B, the one-way valve 2B and the air inlet 32B of the pressure release valve B, and the pressure release hole of the pressure release valve A is opened in the same way. The water in the water stopping cup B starts to flow into the water tank from the pressure relief water outlet 24, the water stopping cup A is communicated with the water stopping cup B, the buoy A and the buoy B start to fall simultaneously, the backpressure pad on the lifting rod is opened, the air leakage hole 3 of the pressure relief valve A leaks air, the pump membrane 4 returns to the pump membrane 4 under the action of the rebound sealing sheet 6 and the return spring 34, the push rod 5 and the pump membrane 4 return, the sealing ring 7 is closed, the pressure relief opening 8 stops water outlet, and the pressure relief hole of the upper cover of the valve stops pressure relief.

Because the valve upper cover 10 is provided with the diversion trench 22, the upper section of the upper cover is connected with the lower section, the pressure of the lower section of the upper cover is greater than that of the upper section at the moment, the water stop gasket 11 is closed, the valve A stops water outlet, and the water outlet of the body A stops water outlet.

Meanwhile, when the B buoy descends to a certain degree, the pressure relief hole of the upper cover of the B valve starts to relieve pressure, the pressure of the upper section of the B valve is larger than that of the lower section, the water stop gasket 11 is opened under the action of water pressure, the B valve is opened, the water outlet of the B body discharges water, and the T-shaped gasket 36 is attached to the air hole of the upper anti-siphon cover 35 under the action of water pressure.

4. Because the C water stopping cup is connected with the D water stopping cup, a flow control hole 37 is arranged between the C water stopping cup and the B water stopping cup, and the speed of water in the C water stopping cup flowing to the B water stopping cup is controlled.

Therefore, when the C water stopping cup and the D water stopping cup fall to a certain degree, the C buoy and the D buoy start to fall simultaneously, the pressure of the pressure releasing hole of the upper cover of the C valve is released, the upper section pressure of the C valve is larger than the lower section pressure, the water stopping pad 11 opens the C valve under the action of water pressure, and the water outlet of the C body is used for discharging water.

Because the front end of the water outlet of the C body is provided with the water replenishing water outlet 20 of the C valve, when the water outlet of the C body is discharged, part of water flows into the water replenishing water inlet of the water stopping cup through the water replenishing port of the C valve, and water is replenished to the A, B water stopping cup. Because A, B stagnant water cup is linked together, float A rises with B float simultaneously this moment, and float A will lose heart hole 3 and close, and B upper cover pressure release hole closes simultaneously, and B valve closes.

5. The C body delivery port front end is provided with the venturi reason pipe, and A shrinks gradually to the B section, and B is the short straight tube to C for the throat, for the position of C valve negative pressure mouth, and C is the pipeline that enlarges gradually to D, consequently when C body delivery port goes out water, C valve negative pressure mouth produces the adsorption, because, C valve negative pressure mouth and water tank bottom are linked together, and the water of water tank the inside is discharged from C body delivery port under the adsorption of negative pressure, and the water tank surface of water begins to descend, ensures next duty cycle.

And simultaneously, the buoy is descended, the air leakage hole of the pressure release valve B is leaked, and the pressure release hole of the pressure release valve B stops releasing pressure under the action of the rebound silica gel piece and the return spring.

After the water in the water stopping cup A and the water stopping cup B is filled, redundant water flows into the water stopping cup C and the water stopping cup D from the water stopping cup B through the flow control hole between the water stopping cup C and the water stopping cup B, so that the buoy C rises, the valve C is closed, the buoy D rises, and the air leakage hole of the pressure release valve B is closed.

The utility model discloses directly connect A valve and A relief valve, A relief valve is connected with connecting rod headstock gear again, B valve, C valve then directly connect the connecting rod headstock gear, the bottom of B connecting rod headstock gear is equipped with B relief valve, B relief valve is connected with D connecting rod headstock gear, through adjusting the mutual cooperation of a plurality of factors, the play water opening time and the closing time of three valve are controlled from this, make to switch more freely between each valve, the drainage time is more stable, the switching effect of each valve is more obvious, reach the stage effluent of excellent performance; compare the solenoid valve, the utility model discloses simple structure, product property can be stable, need not voltage, uses the music score, and is with low costs, and the commonality is strong, and it is higher to produce manufacturing efficiency moreover.
