Compact water turbine main water inlet ball valve structure

The utility model discloses a main water inlet ball valve structure of a compact water turbine, and belongs to the technical field of water-turbine generator set devices. The structure comprises a valve seat body, the valve seat body is provided with a servomotor used for driving the ball valve to be opened/closed, the servomotor comprises a driving mechanism fixedly assembled on the valve seat and a driven mechanism fixed on a valve pivot, and the driving mechanism is matched with the driven mechanism to enable the driven mechanism to rotate so as to drive the valve pivot to rotate; according to the compact type main water inlet ball valve structure of the water turbine, the structural design of a traditional crank arm or a swing type servomotor is avoided, the compact design of the whole structure is better achieved, and the effects that the stroke of the servomotor is short, and the control response of the ball valve is fast are achieved. 本实用新型公开了一种紧凑式水轮机主进水球阀结构，属于水轮发电机组装置技术领域；该结构包括阀座本体，在阀座本体设置有用于驱动球阀开启/闭合
