Beschreibung
Zusammenfassung:	The utility model relates to the technical field of valve reverse blocking, and discloses a multi-fan parallel check valve reverse blocking mechanism which comprises an input pipeline, one end of the input pipeline is connected with a flow dividing head, two ends of the flow dividing head are connected with input flow dividing pipes, one end of each input flow dividing pipe is connected with a fan, and a reverse blocking mechanism is installed in each input flow dividing pipe. One end of the output shunting pipe is connected with filtering equipment, a one-way valve is mounted on the axial surface of the output shunting pipe, and one end of the filtering equipment is connected with an output pipeline. According to the multi-fan parallel one-way valve reverse blocking mechanism, the rotating rod is loosened by unscrewing the fixing pin, then the rotating handle is rotated to drive the rotating rod to rotate, the rotating rod drives the reverse blocking piece to rotate, the reverse blocking piece can be closed
