description The invention discloses a low-fluid kinetic energy loss type multifunctional pump control valve, and relates to the technical field of multifunctional pump control valves, the low-fluid kinetic energy loss type multifunctional pump control valve comprises a valve body with a liquid inlet pipe and a backflow pipe, a pump body, a diaphragm, a valve rod, a small valve clack, a large valve clack and a supporting plate with a flow channel opening are arranged in an inner cavity of the valve body, a liquid leakage hole is formed in the axis of the large valve clack, and the flow channel opening is communicated with the liquid leakage hole. And the through-flow unit is used for reducing the contact area of high-pressure water flow and the lower end face of the large valve clack after the valve body is opened, so that the blocking effect of the large valve clack on the high-pressure water flow is reduced. According to the pump control valve, when the large valve clack ascends, through the abutting effect of the abutt
