| description | The utility model discloses a universal backflow device. The universal backflow device comprises an upper plate, a backflow end cover, a backflow device, a protection plate and a bridging piece, the upper plate is of a song groove type groove structure, a backflow through hole is formed in one end of the upper plate, and the upper plate is connected with the backflow end cover and the backflow device through a positioning structure. A backflow groove structure is arranged on the backflow end cover; the section of the backflow device is correspondingly consistent with the groove surface of the backflow groove in shape; the backflow groove structure and the backflow device are combined to form a backflow channel, and deflection-free operation of the balls in the backflow channel can be achieved. The backflow groove, the backflow structure and the groove structure form an internal backflow space for reciprocating operation of the balls; the backflow end cover is connected with the bridging piece; the ball smooth |
