Intelligent control valve for pressure swing adsorption nitrogen making device and control method of intelligent control valve

The invention relates to an intelligent control valve for a pressure swing adsorption nitrogen making device and a control method thereof, and the intelligent control valve comprises an input module which is used for receiving a purity electric signal corresponding to oxygen purity measured by an oxygen analyzer in unit time; the logic module is used for converting the received purity electric signal into a corresponding control electric signal; the control module is used for generating a valve control electric signal according to the received control electric signal; the valve execution module is used for adjusting the opening degree of the valve; and the proportional control module is used for controlling the valve execution module to work according to the valve control electric signal. According to the invention, qualified nitrogen can be produced within 3 minutes after starting up, so that the nitrogen yield is effectively improved, the waste is reduced, and the nitrogen production efficiency can be impro
