The invention discloses a water conservancy control valve used for water conservancy control. The water conservancy control valve comprises a valve body, a valve element and a water pressure control assembly. Because the water pressure control assembly is arranged in the valve body of the water conservancy control valve disclosed by the invention, the water pressure control assembly is used for controlling the movement of the valve element to open and close the valve element; and the control manner of the water pressure control assembly for the valve element is as follows: when a water pressure of a water inlet port is a certain value greater than a water pressure of a water outlet port, water in the water inlet port can open the valve element, so that an opening pressure of the valve element can be set through the water pressure control assembly, and when the pressure of the water inlet port achieves a pressure needed for opening the valve element, the valve element is opened, so that the water inlet port communicates with the water outlet port, and when the pressure of the water inlet port does not achieve the pressure needed for opening the valve element, the valve element always seals a flow guide channel, and the water inlet port and the water outlet port are cut off by the valve element, so that the valve element can be automatically opened and closed according to the water pressure.
