Abstract

The invention discloses a device capable of achieving automatic switching between electric control and manual control of an electric valve. The device comprises an intelligent controller, a rotary mechanism and the electric valve. The rotary mechanism is arranged on the electric valve and connected with the intelligent controller. The rotary mechanism rotates under the control of first control signals sent by the intelligent controller to achieve the switching between the electric control mode and the manual control mode of the electric valve. Due to the fact that the automatic switching between the electric control and the manual control of the electric valve is achieved, the administration authority of switching of working modes of the electric valve is improved, the randomness of manual switching is avoided, and some improper behaviors can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a device for automatically switching electric control and manual control for an electric valve. Background technique [0002] At present, there are two types of electric valves: electric control and manual control. The switch between electric control and manual control is switched through a handle. This is very convenient for most cases, but in some special cases, the electric valve needs to be operated with authority, such as the opening and closing of the valve requires authority to operate, and the handle can not achieve effective authority management by switching between electric control and manual control. . Contents of the invention [0003] The invention provides a device for automatically switching between electric control and manual control for an electric valve, which is used to realize the automatic switching between electric control and manual control, i...
