Plane sealed self-operated flow control valve

The invention provides a plane sealed self-operated flow control valve. The valve comprises a valve body, wherein a liquid inlet and a liquid outlet are formed on the valve body and are separated from each other by a plane friction pair structure consisting of a plane movable sheet and a plane fixed sheet; both the movable sheet and the fixed sheet are provided with a through flow hole; and the axial direction of the movable sheet is fixedly connected with a valve shaft. The movable sheet is driven by the valve shaft, the overlapping area of the through flow holes of the fixed sheet and the movable sheet is changed through relative displacement, and overflow sectional area is changed, so that the flow of a medium passing through fluid is changed, and the flow of the medium can be completely cut off when the valve is needed to be closed. A member with a flow setting and adjusting function of the self-operated flow control valve is mainly improved, so that the flow setting and adjusting function is ideal, and t
