Adjustable ultrahigh-pressure flow valve for synchronous action of jack cluster

The invention provides an adjustable ultrahigh-pressure flow valve for jack cluster synchronous action. The adjustable ultrahigh-pressure flow valve comprises a lower valve body, a sliding valve element, a throttling opening, a spring, an adjusting rod and an upper valve body. A through hole cavity is formed in the position of the axis in the lower valve body, the sliding valve element is installed in the cavity and can linearly slide along the cavity, a center penetrating oil channel is formed in the position of the center axis of the sliding valve element, and a spring limiting step is arranged at the top of the sliding valve element. One end of the spring abuts against the limiting step surface, and the other end abuts against the bottom of the adjusting rod; the throttling opening is in threaded connection with the lower end of the sliding valve element, a small hole is formed in the side wall of the valve element and communicated with an axis hole of the sliding valve element, an annular groove is formed
