[0044] The utility model will be further described in detail below with reference to the embodiments shown in the drawings.

[0045] The valve for irrigation in this embodiment comprises:

[0046] A valve body 1, which has at least two input interfaces 2 and at least one output interface 3, and the input interfaces 2 and the output interface 3 are in communication.

[0047] A valve core assembly 5 is arranged in the valve body 1 to control the mutual connection or closing between two or more input interfaces 2 and one or more output interfaces 3. In the process of using the control valve, two or more different fluids can enter the valve body 1 from the two or more input interfaces 2, and then the valve core assembly 5 can be used to output only the fluid from one of the input interfaces 2 through the output interface 3, or output the mixed fluids from the multiple input interfaces 2 through the output interface 3, so as to realize the water and fertilizer mixing effect. The above process only needs to control the valve core assembly 5, compared with the prior art, the number of components to be controlled is greatly reduced, and the control cost is reduced. In the embodiment, the input interfaces 2 are not limited to two, and generally three or more are arranged. Correspondingly, multiple output interfaces 3 can be arranged to realize the effect of multiple output.

[0048] Further, the valve core assembly 5 comprises:

[0049] A fixed valve plate 51 is fixedly arranged in the valve body 1, and the fixed valve plate 51 is provided with at least two through holes corresponding to the at least two input interfaces 2.

[0050] A movable valve plate 52 is rotatably arranged on the fixed valve plate 51, and the movable valve plate 52 is provided with at least one flow guide hole corresponding to the output interface 3. The movable valve plate 52 rotates on the fixed valve plate 51, and the straight-through channel is opened or closed by whether the flow guide hole coincides with the through hole of the fixed valve plate 51. In operation, when the flow guide hole coincides with the through hole of the fixed valve plate 51, the straight-through channel is open, and the fluid can pass through; when the flow guide hole does not coincide with the through hole of the fixed valve plate 51, the straight-through channel is closed. In the embodiment, the fixed valve plate 51 and the movable valve plate 52 are combined into a planar valve structure, and the opening and closing of the flow channel are controlled by whether the flow guide hole coincides with the through hole. In addition, the flow rate of the flow channel can be accurately controlled by partially overlapping the flow guide hole and the through hole. A plurality of through holes can be arranged on the fixed valve plate 51 to realize the effect of controlling multiple channels by one valve assembly 5, so that two or more fluid inputs can be adjusted by using the least components.

[0051] Further, the fixed valve plate 51 is provided with a blind hole, and the straight-through channel is closed by whether the blind hole coincides with the flow guide hole. When the blind hole coincides with the flow guide hole, the fluid is blocked. The blind hole design can realize the closing effect of the valve, and can also effectively store the foreign matter scraped off by the movable valve plate 52 on the fixed valve plate 51 during operation, so as to avoid the problem that the foreign matter is stuck between the movable valve plate 52 and the fixed valve plate 51 to cause the valve assembly 5 to fail to operate.

[0052] Further, the blind hole is directly formed on the fixed valve plate 51, or a through hole is formed on the fixed valve plate 51, and a closed cavity 6 is arranged in the valve seat body 4, and the through hole and the closed cavity 6 are combined to form the blind hole. In actual application, the fixed valve plate 51 and the movable valve plate 52 are most suitable for ceramic plates, and the blind hole is designed to be combined with the through hole on the fixed valve plate 51 and the closed cavity 6 on the valve body, which can effectively facilitate the production of the fixed valve plate 51.
