Problems solved by technology

[0003] For example, a digital intelligent linear stroke electric actuator with a publication number of "CN109915642A" discloses an electric actuator capable of self-diagnosis and reduced maintenance frequency. In the event of power loss, the motor has no power after power loss, and the actuator cannot open or close the valve, which is likely to affect the process flow

Abstract

The invention discloses an intelligent electric actuator capable of being switched on and switched off after power failure. The intelligent electric actuator comprises a pipeline butt joint valve, a protective cover and a butt joint pipe, wherein the pipeline butt joint valve is connected with the protective cover through a butt joint pipe, and a conduction cavity opened and closed by an opening and closing execution mechanism is formed between the liquid inlet end and the liquid outlet end of the pipeline butt joint valve; the opening and closing execution mechanism comprises a sinking and floating bottle, a piston disc body installed in the sinking and floating bottle, an extending rod piece connected with the bottom end of the sinking and floating bottle and a flow blocking plug arranged at the end of the extending rod piece, wherein the sinking and floating bottle is provided with an elastic assembly driving the sinking and floating bottle to reset, and a threaded part is arranged on the outer edge of the extending rod piece. The threaded part is meshed with a bevel gear installed in the butt joint pipe to achieve manual adjustment, and the bevel gear is provided with a shaft rod coaxial with the bevel gear. According to the intelligent electric actuator capable of being switched on and swtiched off after power failure, after power loss, the spring resets to enable the valve to be closed, safety protection of the field technological process is achieved, and accidents are completely eradicated.

Description

technical field [0001] The invention belongs to the technical field of electric actuators (H02K7 / 10), and in particular relates to an intelligent electric actuator which can be switched after power failure. Background technique [0002] Electric actuators, also known as electric actuators, have the broadest definition for actuators: a drive device that can provide linear or rotary motion, which uses a certain driving energy and works under the action of a certain control signal. An actuator uses liquid, gas, electricity or other energy and converts it into drive action through a motor, cylinder or other device. Its basic types include three driving modes: Part-Turn, Multi-Turn and Linear. [0003] For example, a digital intelligent linear stroke electric actuator with a publication number of "CN109915642A" discloses an electric actuator capable of self-diagnosis and reduced maintenance frequency. In the event of power loss, the motor has no power after power loss, and the ...
