PLUG-IN SOCKET JOINT SECURED AGAINST SLIDING MOVEMENT

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.
