摘要

A ring-packed pipe spigot-and-socket connection in which an elastic rubber packing ring having an essentially V-shaped cross section is disposed in an annular groove provided in the inside wall of a socket in such a way that prior to the insertion of the spigot end, one of the two legs of the V-shaped packing ring lies substantially axially aligned and turned toward the outlet of the socket, while the other leg extends substantially radially into the interior of the socket. After insertion of the spigot end, the two legs of the V-shaped packing ring provide a seal at the external wall of the spigot end. In the process, the segment of the packing ring facing the two sealing legs, i.e. the "foot segment", seals against the bottom of the annular groove. The annular groove has the shape of a substantially shallow V-shaped chamber and is of such a width that it can accommodate the spread-out packing ring completely when the spigot end has been inserted in the socket. On its two axially opposite ends, the annular groove is bound by radially extending circular ring surfaces, whose radially innermost edge is defined by the intersection of the surface with the cylindrical inside wall of the socket. The foot segment of the packing ring is of toroidal design in the manner of the ball of a ball-and-socket joint and rounded off relatively flatly or shallowly. It lies in a recess whose profile is complementary to the profile of the foot segment and which has been provided axially approximately in the center of the circular groove having been designed in a shallow V-shape. This recess acts as an annular socket like that in a ball-and-socket joint for the foot segment of the packing ring. It accommodates and blocks the foot segment of the packing ring against axial displacement, but permits flexure of the ring in the recess of the groove. The recess is preferably slightly undercut in the direction toward the base of the socket.
