The invention relates to a torque self-adaptive bidirectional non-clogging rotating threaded rod type motor valve. The torque self-adaptive bidirectional non-clogging rotating threaded rod type motor valve is characterized in that a motor gear is arranged on a motor output shaft and meshed with a large gear on the lower portion of a duplicate gear, and a transmission gear is arranged on a transmission threaded rod and meshed with a small gear on the upper portion of the duplicate gear. The transmission threaded rod is arranged between an upper supporting plate and a lower supporting plate in a limited mode, and the upper portion of the transmission threaded rod extends out of the upper supporting plate to be connected with a valve seal assembly in a matched mode. An internal thread is arranged in the transmission gear, and the transmission threaded rod is provided with a threaded section matched with the internal thread of the transmission gear. An upper spring and a lower spring are arranged outside the tran
