摘要： The plug-in socket joint secured against sliding movement is intended for socket pipes manufactured by centrifugal casting, in which the spigot end of one pipe may be inserted with radial play into the socket end of the other pipe. In this joint, a sealing ring and a clamping ring structurally separate therefrom are arranged, said clamping ring being composed of a plurality of clamping segments spaced from one another in peripheral direction. The latter have a spherical outer shell surface, are connected to each other in peripheral direction by means of a moulded-on intermediate layer of rubber or similar and each have a toothing on their inner surface. A holding part, which may be fixed in the area of the socket face end and supporting same, is formed on the clamping ring and comprises a connecting section extending to the clamping ring and tapering approximately conically, and may be expanded together with the clamping ring in dependence on the outer dimensions of the spigot end to be inserted and may thus be extended in axial direction. To prevent the toothing of the clamping segments from corroding as a result of penetrating moisture and oxygen, the connecting section is provided in its area extending from the clamping ring with the clamping segments to the holding part with at least one ring-shaped sealing edge protruding radially inwards and elastically enclosing the spigot end of the inserted pipe.

摘要： The spigot-and-socket point which is secured against sliding is designated for moulded parts and for socket pipes (1) produced by the centrifgual casting technique, with the spigot end (3) of the one pipe adapted to be slid, with radial play, into the socket end (2) of the other pipe. In the socket end there are arranged a sealing ring (8) and a separate clamping ring (14) comprising a plurality of circumferentially extending, spaced clamping segments (15) having a spherically convex outer surface (17) and, on their inner surface (18), a tooth system (19) which, in the presence of axial forces, presses radially onto the spigot end (3) as the spherically convex surface (17) cooperates with a pipe socket's inner surface (18) which tapers conically towards the end. An elastomer support member (20), which can be fixed in its position at the socket face end and supports the same, is provided on the clamping ring (14). A form, which ensures proper retention also in the case of increased rated widths, is obtained when the support member's annular disk-shaped portion (23), which bears on the socket front face (22), comprises a reinforced transition region (26) of increased flexural strength in the region of the inner edge of the socket front face, with the portion (24) connecting to the clamping ring (14 issuing therefrom, and when the socket front face (22) has at its inner edge a recess matching the cross section of the reinforced transition region (26). There a steel ring (28), which increases the flexural strength and can be optionally inserted via an axial insertion slit (29), is cooperating with the reinforced transition region (26) of the support member.
