A moving ring seat of a mechanical seal device

Abstract

The invention discloses a movable ring base of a mechanical sealing device. The movable ring base comprises a movable ring base body (1); the movable ring base body (1) is provided with a movable ring sleeving cavity (3) for sleeving a movable ring (2); multiple first radial convex edges (4) are peripherally distributed at the edge of the movable ring base body (1); a second radial convex edge (5) is arranged on the edge of the movable ring base body (1) between the first radial convex edges (4); the outer diameter of the second radial convex edge (5) is smaller than the outer diameters of the first radial convex edges (4); the second radial convex edge (5) is connected with the side part of one adjacent first radial convex edge (4), and has a spacing distance from the other adjacent first radial convex edge (4); and straight transmission inner walls (3.1) are peripherally distributed on the inner side wall of the movable ring sleeving cavity (3). The movable ring base can effectively shorten the axial assembly length, and can transfer the torque.

Description

technical field [0001] The invention relates to the technical field of mechanical seal components, in particular to a dynamic ring seat of a mechanical seal device. Background technique [0002] At present, most of the mechanical seals for pumps are assembled by end-to-end connection, especially the connection between the moving ring seat and the spring seat, and the connection between the moving ring seat and the moving ring. The connection length is too long, and positioning pins need to be set separately to transmit the torque, resulting in an increase of parts and the structure cannot be simplified. For this reason, the specific structural design of the moving ring seat is a key component to effectively shorten the overall axial length of the mechanical seal device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a moving ring seat of a mechanical seal device that can effectively shorten the axial fitting le...
