The utility model relates to the field of valves, in particular to a bidirectional three-eccentric center butterfly valve grinding device which comprises a motor, a coupler, a rotating shaft, a bearing support, a deep groove ball bearing and a one-way thrust bearing. The motor is connected with one end of a rotating shaft through a coupler, and a grinding assembly is arranged at the other end of the rotating shaft. The bearing support is arranged outside the rotating shaft; the one-way thrust bearing and the deep groove ball bearing are sequentially arranged between the bearing support and the rotating shaft from the end close to the motor to the end close to the grinding assembly. According to the bidirectional three-eccentric center butterfly valve grinding device, the machining cost is saved, meanwhile, the grinding precision is guaranteed, the bidirectional pressure test qualification rate reaches 100%, and the machining requirement for bidirectional sealing of products can be met. 本实用新型涉及阀门领域，尤其涉及一种双向三偏心
