[0005] Furthermore, a positioning hole is provided on the outer baffle, the positioning hole corresponds to the connecting bolt, and the positioning hole is located outside the annular protrusion.

[0006] Furthermore, the annular protrusion is coaxially arranged with the annular body.

[0007] Furthermore, the diameter of the inner baffle is smaller than that of the outer baffle.

[0008] Furthermore, the main shaft flow channel hole and the annular body are both circular.

[0009] Furthermore, the annular body, the outer baffle, the annular protrusion and the inner baffle are an integrally formed structure.

[0010] Beneficial effects of the utility model:

[0011] The ferrule-type sealing ring of the utility model forms a card-mounted structure through the cooperation of the outer baffle plate, the inner baffle plate and the annular body, so that the ferrule-type sealing ring is card-mounted at the flow channel hole of the main shaft without bonding and fixing, and a line seal is achieved with the sector-shaped filter plate through the annular protrusion; at the same time, the ferrule-type sealing ring is further positioned through the cooperation of the positioning hole and the connecting bolt, and the ferrule-type sealing ring will not fall off or be misplaced when the sector-shaped filter plate is disassembled, thereby preventing the sealing leakage between the sector-shaped filter plate and the main shaft and facilitating the installation of the sector-shaped filter plate.
