Power station water intaking valve servomotor control hydraulic operated valve

The utility model discloses a power station water intaking valve servomotor control hydraulic operated valve comprises left adjustment pole (1), left end lid (2), control piston 1 (3), main piston (4), flange (5), control piston 2 (6), valve body (7), right adjusting lever (8), right -hand member lid (9) and lock nut (10). The device adjusts the switching speed of servomotor through the motion scope of adjusting lever limitation control piston to the switching time of control water intaking valve. This device main piston tip is circular bead cavity under the prerequisite of proof strength to the less processing degree of difficulty of length of reducing the valve body is and the switching -over impact that buffer can reduce big latus rectum switching -over valve is constituteed to hollow circular bead and end cover. The main piston is equipped with the voltage -sharing through -hole, and little movement resistance guarantees that piston motion is smooth and easy. 本实用新型公开种水电站进水阀接力器控制液动阀由左调整杆(1)、左端盖(2)、控制活塞1(3)
