Because the lower end of the T-shaped gasket 36 is provided with the gap, air passes through the lower end of the T-shaped gasket 36 from the upper siphon-proof cover 35 and enters the upper end of the valve B, and siphon is prevented from being generated when the valve B is closed.
The working principle of the invention 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, and the water outlet pipe of the valve C is provided with the water replenishing water outlet 20 of the valve C and is connected with the 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 rise simultaneously until the valve B is closed and the air leakage hole 3 above the valve A is closed. Because C stagnant water rim of a cup portion highest position is higher than B stagnant water rim of a cup portion highest position, so when A stagnant water cup and B stagnant water cup water full back C valve continue the moisturizing, unnecessary water flows to the water tank, and the surface of water tank rises this moment, and until being higher than C stagnant water rim of a cup portion highest position, the rivers of water tank flow into C stagnant water cup, close C valve.
2. Press atmospheric pressure button 1, atmospheric pressure passes through pneumatic tube 25 through check valve 2, through air inlet 32, because the hole 3 that loses heart closes, pump membrane 4 promotes push rod 5 forward movement under the effect of atmospheric pressure, sealing washer 7 is opened, the water of A valve upper cover upper segment passes through pressure release hole 8, discharge from pressure release delivery port 24, because the upper cover pressure release hole 23 pressure release on the A valve upper cover, the pressure of A valve upper segment is greater than the pressure of hypomere this moment, water stop pad 11 is opened under hydraulic effect, the A valve is opened, A body delivery port goes out water. Because the setting of the front end outlet pipe of A body delivery port is venturi tube, A shrinks gradually to the B section, and B to C are the short straight tube of throat, that is the position of A valve negative pressure mouth 30, and C to D are the pipeline that enlarges gradually, consequently when A body delivery port goes out water, A valve negative pressure mouth 30 produces the negative pressure, because A valve negative pressure mouth 30 communicates with the bottom of water tank, and the water of water tank the inside is discharged from A body delivery port under the effect of negative pressure. The water level in the cistern begins to drop, so that the adjustable water outlet 28 of the water cup B and the adjustable water outlet 29 of the water cup C start to drain.
At the moment, the water stopping cup A, the water stopping cup B and the water stopping cup C descend simultaneously, and the adjustable water outlet 28 of the water stopping cup B is larger than the adjustable water outlet 29 of the water stopping cup C because the water stopping cup B is communicated with the water stopping cup A.
Because B stagnant water cup is linked together with A stagnant water cup, consequently the A flotation pontoon descends with B flotation pontoon simultaneously, lifts the back pressure pad 21 on the pole and opens, and the hole of disappointing 3 on the relief valve is lost heart, and pump membrane 4 is under the effect of resilience formula silica gel gasket 6 and return spring 34, and push rod 5 and pump membrane 4 return, and sealing washer 7 closes, and pressure release delivery port 24 stops out water, and upper cover pressure release hole 23 stops the pressure release.
3. Because the upper cover 10 of the valve is provided with the diversion trench, the upper section of the upper cover is communicated with the lower section, the pressure of the upper section of the upper cover is higher than that of the lower section, the water stop gasket is closed 11, the valve A stops water outlet, and the water outlet A stops water outlet.
Meanwhile, when the B buoy descends to a certain degree, the pressure of the upper cover pressure relief hole of the B valve is relieved, the pressure of the lower section of the B valve is larger than that of the upper section, the water stop pad 11 is opened under the action of water pressure, the B valve is opened, and the water outlet of the B body is used for discharging water. The T-shaped gasket moves upward under the action of water pressure and is tightly fitted with the anti-siphon upper cover 35.
Meanwhile, when the buoy in the C water stopping cup descends to a certain degree, the pressure of the upper cover pressure relief hole of the C valve is relieved, the lower section pressure of the C valve is greater than the upper section pressure, the water stopping pad 11 is under the action of water pressure, the C valve is opened, and water is discharged from the water outlet of the C body.
4. Because the front end of the water outlet pipe of the valve C is provided with the water replenishing water outlet 20 of the valve C, when the water outlet of the body C is discharged, part of water flows into the water stopping cup B through the water replenishing water outlet 20 of the valve C and the water replenishing water inlet 26 of the water stopping cup B, because the water stopping cup B is communicated with the water stopping cup A, the float bowl A and the float bowl B rise simultaneously to close the air leakage hole 3 above the valve A, and meanwhile, the pressure leakage hole of the upper cover of the valve B is closed, and the water outlet of the body B stops discharging water. At the moment, the T-shaped gasket returns under the action of gravity, and air enters the water outlet of the B body from the hole of the anti-siphon upper cover through the lower part of the T-shaped gasket to prevent the siphon phenomenon.
5. Because the mouth part of the water stopping cup B is lower than the mouth part of the water stopping cup C, after the valve A and the valve B are closed, the valve C continues to replenish water for the water stopping cup B, the redundant water in the water stopping cup B continuously flows into the water tank from the mouth parts of the water stopping cup A and the water stopping cup B, the water surface in the water tank begins to rise at the moment until the water surface is higher than the mouth part of the water stopping cup C, and the valve C is closed at the moment.
According to the invention, the valve A is directly connected with the pressure release valve, the pressure release valve is also connected with the connecting rod opening and closing device, the B, C valve is directly connected with the connecting rod opening and closing device, and the water outlet opening time and closing time of the three valves are controlled by adjusting the mutual cooperation of a plurality of factors, so that the valves are switched freely, the water discharging time is more stable, the switching effect of each valve is more obvious, and the excellent performance of discharging water by stages is achieved; compared with an electromagnetic valve, the electromagnetic valve has the advantages of simple structure, stable product performance, no voltage, spectrum usage, low cost, strong universality and higher production and manufacturing efficiency.
