[0036] The first control unit 5 is fixedly connected to the outer upper part of the extension arm 13. On both sides of the upper part of the main body 1, a first accommodation cavity 11 and a second accommodation cavity 12 are respectively provided.

The second lifting rod 91, the second lifting rod spring 92, and the second control unit 8 cooperate to control the opening and closing of the second water stop assembly 7. The second control unit 8 is an active trigger type, and its triggering method can be a wire rope type, a mechanical pressing type, a pneumatic control type, or an electric control type.

[0039] An independent water passage 111 and a water passage 121 are provided on the main body 1. The water passage 111 communicates with the middle hole of the first water stop surface 112, and the water passage 121 communicates with the middle hole of the second water stop surface 122; the water outlet cover 33 is fixedly connected to the main body 1. The water outlet cover 33 is provided with a first water outlet 31 and a second water outlet 32. The first water outlet 31 communicates with the water passage 111, and the second water outlet 32 communicates with the water passage 121. The anti-siphon gasket 34 is arranged between the main body 1 and the water outlet cover 33 to provide sealing and anti-siphon functions.

[0040] The water outlet assembly 3 includes the water outlet cover 33 and the anti-siphon gasket 34: The water outlet cover 33 is fixedly connected to the main body 1. The water outlet cover 33 is provided with a first water outlet 31 and a second water outlet 32. The first water outlet 33 communicates with the first water passage 111, and the second water outlet 32 communicates with the second water passage 121. The anti-siphon gasket 34 is arranged between the main body 1 and the water outlet cover 33 to provide sealing and anti-siphon functions.

[0041] Further, the first control unit 5 is composed of an outer floating bucket 51, an inner floating bucket 52, and a one-way valve 53. The movement of the inner floating bucket 122 is controlled by the water level in the water tank. It moves up and down with the change of the water level, thereby driving the first lifting rod 62 and the first lifting rod connecting arm 61 to rotate, and further controlling the opening and closing of the first water stop assembly 4.

[0042] Further, a water outlet cover positioning hole 331 is provided on the side of the water outlet cover 33, and a water outlet cover positioning buckle 115 is provided at the corresponding position of the main body 1 to cooperate with it for fixation.

[0043] Further, the second water stop assembly 7 respectively includes: a water stop fixing seat 71, a water stop pad 72, a water stop protection pad 73, a water stop cover 74, a sealing ring 75, a water stop seal cover sealing ring 76, and a water stop seal cover 77, which cooperate with each other. The structures of the first water stop assembly 4 and the second water stop assembly 6 are the same and will not be described in detail.

[0044] During operation: When the water level in the water tank drops, the inner floating bucket 52 drops with the water level drop, thereby driving the first lifting rod connecting arm 61 and the first lifting rod 62 to rotate. The water stop pad opens (here the water stop pad is the water stop pad in the first water stop assembly 4), and water flows into the middle hole of the water stop surface 112 from the gap between the water stop pad and the water stop surface 112, and then enters the first water passage 111 of the main body 1, and finally flows out from the first water outlet 31; When the water level in the water tank rises, the inner floating bucket 52 rises with the water level rise, thereby driving the first lifting rod connecting arm 62 and the first lifting rod 61 to rotate in the opposite direction, and the water stop pad closes (here the water stop pad is the water stop pad in the first water stop assembly 4) to stop water outflow. The up and down movement of the inner floating bucket 52 is passive and changes correspondingly with the up and down change of the water level in the water tank.

[0045] When the second control unit 8 is actively triggered, the second control unit 8 controls the rotation of the second lifting rod 91 and compresses the second lifting rod spring 92, and the water stop pad 72 (here the water stop pad is the water stop pad in the second water stop assembly 7) is opened. Water flows into the middle hole of the water stop surface 122 from the gap between the water stop pad 72 and the water stop surface 122, thus entering the main body second water outlet channel 121 and finally flowing out from the second water outlet 32. When the triggering of the second control unit 8 stops, the second lifting rod 91 rotates in the reverse direction under the elastic force of the second lifting rod spring 92, and the water stop pad 72 (here the water stop pad is the water stop pad in the second water stop assembly 7) closes to stop the water flow. The second control unit 8 is an actively triggered type, and its triggering method can be a wire rope type, a mechanical pressing type, a pneumatic control type or an electric control type.

[0046] The water inlet valve of the present utility model adopts a dual independent control system and can provide two independent water outlet modes.

[0047] In addition to the conventional passively triggered floating bucket control system, an actively triggered control system is also provided, which can be used for the opening of the drain valve, active precise water replenishment, active flushing, etc. Among them, the actively triggered control system can adopt a wire rope type, a mechanical pressing type, a pneumatic control type or an electric control type. When the actively triggered control system is used to open the drain valve, the control system can be conveniently set at any position without being restricted by the position of the drain valve. Both accommodating cavities are arranged on the main body and can be set at different angles, so that although there is one more set of control system compared with the traditional water inlet valve, the overall structure is compact, the external dimension does not increase, and the installation is more convenient.
