AI Technical Summary

Technical Problem

Existing actuators are prone to output shaft jamming when controlling the opening and closing of linear stop valves, limiting their applicability and making it impossible to achieve both manual and electric operation simultaneously.

Method used

A manual-electric actuator was designed, comprising an electric drive component and a manual component. Through the cooperation of a gear structure and an elastic element, reliable movement of the output shaft is achieved, and automatic opening and closing is realized through a micro switch and a transmission gear system, adapting to linear stop valves of different specifications.

Benefits of technology

It achieves anti-jamming of the output shaft, expands the scope of application, and provides a dual choice of manual and electric operation, ensuring the reliability and flexibility of the actuator.
