The center of the surface of the valve cavity 6 is provided with a through water outlet channel, the surface of the valve cavity 6 is provided with a water inlet channel at the outer ring of the water outlet channel, and the front end of the water outlet channel is provided with a water outlet flap 9. The water outlet flap 9 can move, and when the rear end of the water outlet flap is subjected to water pressure, the water outlet flap moves forwards and is separated from the water inlet channel, so that the water inlet channel is opened, and water is pushed forwards.

A sealing ring 10 is arranged between the front end of the inner wall of the end cover 14 and the front end face of the valve cavity 6, the water inlet 15 is positioned outside the sealing ring 10, and the water outlet 16 is positioned inside the sealing ring 10. The rear end of the surface of the sealing ring 10 is provided with an opening corresponding to the water inlet channel on the surface of the valve cavity 6.

The water inlet 15 is always communicated with an external water inlet pipeline, when water is pumped, water flows into the water inlet 15, flows backwards along the outer edge of the sealing ring 1, enters the water inlet channel of the valve cavity 6 from the opening and flows to the rear of the valve cavity 6, and the air bag on the piston 7 is blown to pump water.

The sealing ring 10 can seal the water outlet passage and the water inlet passage, so as to prevent water from directly entering the front end of the valve cavity 6 after entering the end cover 14, and water is prevented from leaking and seeping due to the fact that the valve core 12 is pushed by water flowing channels 111 on the valve plate 11 to move water to flow out along the water outlet 16.

During operation, the gasbag that motor 1 work drove push pedal 4 and continuously extrudees piston 7 makes it blast and draw water, piston 7 carries water to the front side of valve pocket 6 through the inlet channel at valve pocket 6 center, under the effect of pressure, the play water claps 9 motion and makes the inlet channel open, rivers flow in the front side of valve pocket 6, flow into in water runner 111, under the water pressure effect, case 12 extrudees spring 13 and makes its shrink, case 12 breaks away from with valve plate 11 for water runner 111 opens, water flows out from delivery port 16.

The front port of the piston 7 air bag is provided with a water inlet flap 8. When the water inlet flapper 8 does not work, the water inlet flapper 8 is in a stable state and is in contact with the rear end of the water inlet channel on the valve cavity 6, when the water inlet flapper 8 is driven by the air bag on the piston 7 to move, and water flows to the rear of the valve cavity 6 from the water inlet channel and is pushed by the piston 7 to pump water.

As shown in fig. 5, a protruding chuck is disposed at the rear end of the guide rod 122 of the valve core 12, and is inserted into the rear end of the guide hole of the valve plate 11 to position the valve core 12, so as to ensure sufficient contact between the valve core 12 and the valve plate 11 and avoid leakage.

As shown in fig. 6, the valve plate 11 is a flat plate, the center of which is provided with a water flow passage 111, and the valve core 12 is a plug body capable of blocking the water flow passage 111, so that when water is pumped, the valve core 12 is separated from the valve plate 11 under the action of water pressure, and water flows out from the water flow passage 111. The rear end of the valve core 12 is provided with a positioning block 121, and the front end of the spring 13 is sleeved on the positioning block 121, so that the spring 13 is more stably contacted with the valve core 12, and deviation is prevented.

When the water valve works, water flow enters from the water inlet 15, flows backwards along the outer edge of the sealing ring 1 and enters the water inlet channel of the valve cavity 6 from the opening, the motor 1 works to drive the eccentric wheel 3 to rotate, thereby driving the push rod 17 to rotate, the push plate 4 is pushed by the top end of the push rod 17, the protruding position of the push plate 4 keeps moving, the push plate is sequentially contacted with different air bags on the piston 7, the air bags are extruded to be blown, water flows to the rear part of the valve cavity 6 from the water inlet channel and is blown by the piston 7 to enter the water outlet channel at the center of the valve cavity 6, and the water outlet flap 9 is pushed to be separated from the valve cavity 6, when water enters the water flow channel 111 in the valve plate 11, the valve core 12 moves forwards to be separated from the valve plate 11 under the action of water pressure, the spring 1 is extruded to contract, the water flow channel 111 is opened at the moment, water flows out through the water outlet 16, and when water is not pumped, the valve core 12 is tightly attached to the valve plate 11 under the action of the elastic force of the spring 13, so that water sealing is realized.
