Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to an intelligent electric actuator. Background Art

[0002] Currently, more and more factories are adopting automated control, with manual operations being replaced by machinery or automated equipment. Actuators are required to serve as the interface between the control system and the mechanical movement of valves. Furthermore, they are required to enhance safety and environmental performance. In some hazardous situations, automated actuators can reduce personal injury. Certain valves require emergency opening or closing under special circumstances, and valve actuators can prevent the spread of danger while minimizing plant losses. However, existing electric valve actuators still present certain issues, which can make their use somewhat inconvenient. For example, most electric valve actuators operate in ambient temperatures between -20°C and +70°C. They are not easily used in extremely low ambient temperatures, and low outdoor temperatures can hinder their operation and potentially shorten their service life. In other words, traditional electric actuators are not suitable for operation in low temperatures or high humidity environments.

[0003] The above problems are in urgent need of resolution. Utility Model Content
