The invention relates to a high-speed switching type multifunctional servo valve which belongs to the technical field of hydraulic pressure and automatic control. The high-speed switching type multifunctional servo valve comprises a controller, four high-speed switching valves, four adjustable valves, a manual control disk, an oil pool, an oil cylinder and an oil pump. The high-speed switching type multifunctional servo valve is used for intelligently controlling a servo oil cylinder by sufficiently utilizing the advantages of quick response and long service life of a two-position, two-way and high-speed switching valve combination and the function of flexible programming of a single chip, thus the best control effect on difference control objects can be achieved; by combining the switching function of the manual control disk, the high-speed switching type multifunctional servo valve can realize a manual control mode and an automatic control mode, thereby guaranteeing the continuity of production and improving the production efficiency. In the automatic control state, the filling amount of hydraulic control ends in the adjustable valves can be adjusted by adjusting the opening time of the two-position, two-way and high-speed switching valve, thus an opening position between a valve core and a valve seat is changed to adjust the flow of working oil going in and out of the servooil cylinder and realize the speed-change control of the oil cylinder. The invention can be applied to all electrohydraulic servo systems and has great practicability and economy.
