Valve control method, device and valve
By acquiring and comparing the target rotation amount and the actual rotation amount of the motor, the problem of difficulty in timely detection of valve core rotation angle accuracy not meeting requirements in electronic valves is solved. This enables precision detection and timely handling of valves during operation, ensuring stable valve performance.

Abstract
The application relates to a valve control method and device and a valve, the valve comprising at least one valve core and a motor corresponding to the valve core, the method comprising: acquiring a target rotation amount and an actual rotation amount of the motor; wherein the target rotation amount is determined based on a target rotation angle of the corresponding valve core in a control instruction, a full stroke angle of the valve core and an actual full stroke rotation amount of the motor; and based on the target rotation amount and the actual rotation amount, whether the actual rotation angle of the valve core meets a first accuracy requirement is determined through a corresponding relationship between the motor rotation amount and the rotation angle of the valve core, the detection of the rotation angle of the valve core is performed in time during the working process of the valve according to the control instruction, and the problem that the accuracy of the rotation angle of the valve core does not meet the requirement and cannot be found in time is solved.
