A flow control valve for test of electric submersible centrifugal oil pump units comprises a wheel casing, a sealing press part, a flow adjusting lever, a valve body, a connecting pipe, a connecting haft, a positioning shaft, a lower valve plate, a worm wheel, a worm and an upper valve plate. The upper valve plate and the lower valve plate can generate press force. When an upper eccentric hole and a lower eccentric hole are not communicated, a runner can be closed. Communicated channels of the upper eccentric hole and the lower eccentric hole can be adjusted by rotating the flow adjusting lever, so that flow can be adjusted. Rotation of the flow adjusting lever is controlled by the worm wheel and the worm, and is low in speed and laborsaving, so that flow is convenient and accurate to control and stable, test data are real and reliable, performance of the electric submersible centrifugal oil pump units can be accurately judged, delivered electric submersible centrifugal oil pump units are guaranteed to be qualified, and the flow control valve has remarkable economic benefits.
