Seal Construction For Bell And Spigot Pipe
View pageUS Patent:
48565610, Aug 15, 1989
Filed:
Nov 10, 1987
Appl. No.:
7/119143
Inventors:
Joseph P. Zicaro - Corona CA
Assignee:
Hydro Conduit Corporation - Corona CA
International Classification:
F16L 918

US Classification:

Abstract:
A section of pipe includes a first body of material disposed in a bell and spigot pipe configuration having a bell portion extending to a bell end, which bell portion defines a radially inwardly facing annular seal groove in which to place a sealing ring to be engaged by a spigot portion of another section of pipe inserted into the bell portion. The seal groove is disposed between first, second, and third circumferentially-extending surfaces, the first surface facing radially inwardly and extending axially between the second and third surfaces, the second surface facing axially toward the bell end and extending radially inwardly from the first surface, and the third surface facing axially away from the bell end and extending radially inwardly from the first surface on an inclined away from the bell end as it extends from the first surface. The third surface engages an inclined third annular surface of a mating sealing ring placed in the seal groove, to thereby inhibit sealing ring displacement by a spigot portion of another section of pipe that engages the sealing ring. One form of the sealing ring includes a fin portion that the spigot portion engages, and a space contiguous the fin portion for fin deformation without sealing ring displacement and development of excessive pressure on the bell portion.
