SPLIT-RING GLAND PIPE COUPLING WITH CORRUGATED ARMOR AND ANNULAR GASKET HAVING PRESSURE ASSIST SLOT |
摘要 |
A pipe coupling for coupling adjacent ends of a pair of pipes includes a sleeve, a split-ring gland positioned around one of the ends of the sleeve, and an annular gasket positioned within the split-ring gland and configured to be compressed by the split-ring gland for sealing one pipe end to the sleeve. The split-ring gland includes two partially circular gland members with spaced ends defining a gap, which is spanned by an armor positioned in the gap to provide a generally closed annular periphery about the gasket. The armor includes a corrugated portion engaging the gasket during compression. The gasket includes a pressure assist slot configured to receive pressurized fluid leaking from the pipes and a plurality of cross grooves ensuring continued fluid communication with the pressure assist slot. The gasket also includes ribs engaging the split-ring gland and the armor to reduce or eliminate added lubrication necessary. |
