Active flow-limiting valve

The utility model provides an active flow-limiting valve, and relates to the field of valves. The active flow limiting valve comprises a valve body, the valve body is divided into an inlet end and an outlet end, a baffle is rotationally connected into the valve body, a center shaft is fixedly installed in the middle of the baffle, the top end of the center shaft penetrates through the valve body and extends to the outer side of the valve body, and a handle is fixedly installed at the end, located on the outer side of the valve body, of the center shaft. According to the active flow limiting valve, the valve is installed in a pipeline, liquid enters the valve through the inlet end, the liquid pushes the blocking piece to rotate inwards after entering the valve, and therefore the liquid can be prevented from flowing through the valve body rapidly, meanwhile, the connecting rod can be dragged through the reset spring to drive the extrusion block to prevent the baffle from rotating, and the pressure sensing plate
