Abstract
The application discloses a low-temperature environment electric actuator in the technical field of electric actuators, which comprises a valve body, a ball valve arranged on the valve body, a drive shaft arranged on the valve body and penetrating through the valve body, an electric actuator body, an installation cylinder arranged on the outside of the drive shaft and at the bottom of the electric actuator body, the installation cylinder being arranged on the valve body, a heat preservation shell arranged on the outside of the electric actuator body and on the installation cylinder, a temperature control switch arranged in the heat preservation shell, a motor arranged in the heat preservation shell, and a heating assembly connected with the output end of the motor. Through rotation of the push plate, the air between the heat preservation shell and the electric actuator body can be pushed to rotate along the circumference, so that the air heated by the electric heating wire can be quickly mixed with other cold air, so that the air between the heat preservation shell and the electric actuator body can be quickly heated, and the electric actuator body can be uniformly heated.
