Abstract

The invention provides an electric valve actuator and a control method. The electric valve actuator comprises an electric valve actuator and a control device, wherein the control device comprises a single-chip microcomputer, a control input module, a control interface module, a power supply module, a self-reset power supply module, a driving module, a stepping motor, a digital-to-analogue conversion module, and an RS485 communication module; the single-chip microcomputer is used for acquiring temperature signals, current input signals, voltage input signals, pressure transmitter signals and reset control signals; the control interface module is used for displaying the valve state and outputting user control signals to the single-chip microcomputer; the single-chip microcomputer outputs control instructions to the driving module according to the received signals, and outputs the current output signals and the voltage output signals to the digital-to-analogue conversion module; the control instructions include control driving instructions and reset instructions; and the power supply module is used for supplying electricity to the single-chip microcomputer and the driving module. According to the electric valve actuator disclosed by the invention, the route switch of the electric valve actuator is changed along with the change of input voltages, current, temperature and voltages, so that the electric valve actuator has a self reset function.

Description

technical field [0001] The invention relates to the technical field of electric actuators, in particular to an electric valve actuator and a control method. Background technique [0002] An electric actuator is a driving device that uses a certain driving energy and provides linear or rotary motion under the action of a certain control signal, because it has the advantages of convenient energy access, fast signal transmission speed, long transmission distance, and convenient centralized control. , It is often used to form an electric valve or an electric regulating valve to form a complete set of various valves. At present, the existing electric actuators used for matching valves are usually connected between the motor and the single-chip microcomputer through a temperature sensor in the control device. control, and cannot freely control the opening of the valve, and cannot actively reset when encountering special circumstances during use, and has defects and problems such ...
