The high-frequency one-way sine flow control valve comprises a sine flow valve, a proportional throttle valve and a fixed differential pressure reducing valve, the sine flow valve is provided with a first oil outlet hole, and the proportional throttle valve and the sine flow valve are connected and matched to form a first overflowing channel and a second overflowing channel which are connected in parallel; constant first flow Q1 which is equal to B is conveyed to the first oil outlet hole through the first flow passing channel, meanwhile, second flow Q2 which is changed according to a sine function curve is conveyed to the first oil outlet hole through the second flow passing channel, Q2 is equal to Asin omega t + A, and finally the flow Q of the first oil outlet hole is equal to Asin omega t + A + B, the flow control valve can output one-way sine flow signals, the technical problem that in the prior art, a flow control valve cannot output one-way sine flow signals is solved, and the beneficial effects that h
