Flow valve control method and apparatus, and storage medium

A flow valve control apparatus, wherein comprising:

• a teach-in module, used for conducting a median current value teach-in of a flow valve starting from an initial median current value of the flow valve, wherein each process of teach-in comprises:
• controlling a current output to the flow valve, so that the flow valve goes through the following processes successively:
• a flow passes for the first time, the output flow makes a shifting mechanism return, a flow passes again, and the output flow makes the shifting mechanism return again;
• recording current values when the flows pass through the flow valve twice as the maximum median current values;
• and
• acquiring a deviation value of each of the maximum median current values and the initial median current value;
• and
• a correction module, used for correcting a flow-current curve of the flow valve based on the deviation value,
• wherein an initial median current value in the first teach-in process is an default median current value, and an initial median current value in a next teach-in process is a corresponding median current value of the flow valve in the flow-current curve obtained by correction in a previous teach-in process.
