Screw 61 is connect the inward flange of flexible gland 3 is pressed on interior casing seal joint face so as to realize by annular pressing plate 51
The sealed connection of flexible gland and inner housing, wherein, it is provided with interior casing seal at the inside edge of annular pressing plate 51
The interior position limiting structure of joint face extension, interior position limiting structure are used to limit between annular pressing plate 51 and interior casing seal joint face
Distance avoids the inward flange of flexible gland from being overly compressed, beyond flexible close to limit the compress variation of flexible gland
The deformation limit of big envelope and follow the string, it is impossible to play sealing effectiveness, in the present embodiment, interior position limiting structure is located at annular pressure
Turned edge on the inside of the inside edge of plate 51, periphery and flexible gland of the outer peripheral face that the inner side turns edge i.e. away from axis side
Periphery block close to axis direction side is brought into close contact with merging, and inner casing is pressed on by annular pressing plate in flexible gland
When on body sealed connection face, the periphery of the close axis direction side of flexible gland is pressed on the outer peripheral face that inner side turns edge
On, sealing effectiveness is played, in other embodiments, interior position limiting structure is the knot that turns edge at annular pressing plate outer ledge
Structure, certainly, interior position limiting structure are also not limited to as the structure that turns edge, or between circumference inside edge or outer ledge
Every the spacing preiection of setting.
It is correspondingly provided with the inward flange and interior casing seal joint face of flexible gland for preventing flexible gland and interior
The interior concaveconvex structure that housing seal joint face relatively moves, in the present embodiment, interior concaveconvex structure is interior casing seal connection
The inner housing annular groove and the inside edge of flexible gland 3 set on face sets corresponding with inner housing annular groove
Inward flange annular convex edge, realized and flexible sealing is enclosed on radially by the inserting of inner housing annular groove and inward flange annular convex edge
Direction it is spacing, avoid in inner housing radial floating, the relative of radial direction occurs for flexible gland and interior casing seal joint face
It is mobile.
The outward flange of flexible gland 3 is tightly connected with shell body 2, and the right-hand member of shell body 2 is provided with turn edge, the turn edge
Right flank be to be tightly connected face for the shell body that is tightly connected with flexible gland, the outward flange of flexible gland passes through outer
Housing connection member and outer ring pressing plate are connected on shell body sealed connection face, and in the present embodiment, shell body connector is shell
Body attachment screw 62, similar to the attachment structure of flexible gland to inner housing, shell body sealed connection face is provided with and shell
The screwed hole that body attachment screw 62 connects, shell body attachment screw 62 is by outer ring pressing plate 52 by the outside of flexible gland 3
Edge is pressed on so as to realize the sealed connection of flexible gland and shell body on shell body sealed connection face, wherein, outer ring pressure
