Description

Technical Field

[0001] This utility model relates to electric valve actuators, and more particularly to a quick disassembly device for an electric valve actuator and a valve body. Background Technology

[0002] Electric valve actuators are key devices in industrial automation control. Their core function is to convert electrical energy into mechanical energy to drive valves to complete opening, closing, or regulating actions. Depending on the application scenario, they are mainly divided into fluid control types (such as electric gate valve actuators) and air system control types (such as electric damper actuators), which differ in principle and structure. Electric gate valve actuators: A motor drives a reducer to convert high-speed rotation into low-speed, high-torque output, driving the valve to open and close. Limit switches monitor the valve opening degree, while limit switches cut off the motor power when the valve reaches the fully open / fully closed position, achieving precise positioning. Electric damper actuators: Powered by single-phase AC power, they receive DC control signals (such as DC 0-10V) and output angular displacement (usually 0-90 degrees) to regulate the damper. Some models are equipped with a fail-safe reset spring, automatically resetting to a preset position upon power failure, improving system safety. Currently, electric valve actuators are cumbersome to disassemble when connecting pipe interfaces. Utility Model Content
