Electrically operated valve transmission device based on inner lifting stop valve

The invention relates to the technical field of control valves, and discloses an electrically operated valve transmission device based on an inner lifting stop valve. The electrically operated valve transmission device comprises a stop valve body, a transmission shaft, a motor, an upper cover plate and an inner sleeve. The stop valve body comprises a valve body and an inner lifting valve element. The inner lifting valve element is mounted in a vertical pipe. The inner sleeve is mounted on the upper end surface of the vertical pipe. The upper end of the inner lifting valve element is positioned inside the inner sleeve. The upper cover plate is mounted at an opening in the upper end of the inner sleeve. The motor is mounted at the upper end of the upper cover plate. An output shaft of the motor penetrates through the upper cover plate and is positioned inside the inner sleeve, and is connected with the upper end of the transmission shaft. The lower end of the transmission shaft is connected with an input shaft
