Beschreibung
Zusammenfassung:	The invention discloses a multistage porous flow-limiting orifice plate device, and relates to the technical field of orifice plate devices, the multistage porous flow-limiting orifice plate device comprises a flow-limiting pipe, flange rings are fixed at two ends of the flow-limiting pipe, and a pressure sensor and a flow control assembly are arranged on the outer surface of the flow-limiting pipe. According to the multi-stage porous flow-limiting pore plate device, when resistance entering a multi-stage porous flow-limiting pore plate needs to be improved, firstly, pressure entering the multi-stage porous flow-limiting pore plate is detected through a pressure sensor, then a forward and reverse motor is started, and small holes in the surface of the first flow-limiting pore plate are shielded by a rotating frame through rotation of the rotating frame; when the resistance entering the multi-stage porous flow-limiting pore plate needs to be reduced, a driving motor is started, a buffer barrel communicates wit
