The invention discloses a low-temperature ball valve seat anti-rotation device and a using method thereof, and relates to the technical field of valves. The low-temperature ball valve seat anti-rotation device comprises a valve body and a bottom plate, and further comprises a fixing mechanism which is arranged on the bottom plate and used for fixing the valve seat body in the assembling process, and the fixing mechanism comprises two first mounting plates which are fixedly connected to the bottom plate and are symmetrically arranged; first electromagnets are arranged on the sides, away from the bottom plate, of the two fixing plates, and first slopes are arranged at the ends, close to each other, of the two fixing plates. According to the low-temperature ball valve seat anti-rotation device and the using method thereof, through the arrangement of the fixing mechanism, under the driving effect of the driving mechanism, the fixing plate is moved to abut against the valve seat body, so that under the magnetic ef
