发明名称 Socket pipe seal for concrete pipes
摘要 A socket seal for a tubular member defining a socket having an open end delimited by a free edge, an inner wall extending from the free edge and a base remote from the open end, and into the open end of which socket a further member is to be inserted to form a sealed connection, the seal being composed of a sealing ring made of an elastomer material and including a holding portion embedded in the tubular member in the region of the outer edge of the socket, a band-shaped fastening portion joined to the holding portion, and a sealing portion joined to the fastening portion and having a configuration such that it has a greater thickness at a point spaced from the fastening portion than at the location where it is joined to the fastening portion. The sealing portion is movable by bending relative to the fastening portion toward the base of the socket from an installation state to an operating state, the ring being configured such that in the operating state one surface of the sealing portion bears against the inner wall of the socket, and in the installation state the sealing ring delimits the free edge of the socket and the one surface of the sealing portion is approximately flush with the inner wall of the socket.
