The invention relates to an intelligent breathing valve, belonging to the technical field of oil and gas storage and transportation equipment. The intelligent breathing valve comprises an outer valve body, an inner valve body, a valve element and a driving device, and is characterized in that the inner valve body is fixedly arranged on the outer valve body through an assembly post; the driving device is arranged on one side of the valve element through an ejection cylinder; and the driving device is movably connected with the valve element. The intelligent breathing valve is simple in structure and ingenious in design; and the aim that the inner pressure of a cylinder body can be automatically adjusted so as to be stabilized in a certain range by controlling opening and closing of an upper valve element and a lower valve element is reached. Besides, the upper valve element and the lower valve element are controlled by adopting a link mechanism, so that rotation is flexible and convenient; the problems of easy
