Description

technical field [0001] The invention belongs to the field of the Internet of Things and intelligent heating, and in particular relates to a flow calibration method and device for an intelligent valve. Background technique [0002] It is an effective way to improve the comfort of heating and realize the efficient use of energy by adjusting the flow of the heating pipeline through intelligent temperature control valves, and then realizing the self-adaptive adjustment of the indoor temperature. [0003] Accurate adjustment of the flow rate of intelligent temperature control valves is the key to realize high-precision indoor temperature adjustment. [0004] In engineering, the flow adjustment is generally realized by adjusting the opening of the valve. However, this method has the following disadvantages: ① There is a nonlinear relationship between the valve opening and the flow rate, and accurate adjustment of the flow rate cannot be realized; ② The influence of multiple facto...
