Mechanical joint connector and joint employing said connector

摘要

A mechanical joint connector and a joint made with the mechanical joint connector are provided for use in connecting the bell ends of fittings and the like, the bell ends being of a mechanical joint-type configuration having an annular gasket-receiving recess extending into the bell from the outer flange surface of the bolt-through flange of the bell, the connector including a cylindrical sleeve and a radially extending flange, with the flange having an annular raised portion extending upwardly from upper and lower surfaces of the flange. The annular raised portions of the flange have upper surfaces which are tapered inwardly from an outer diameter toward the sleeve, such that the raised portion has its maximum height at its outer diameter. The connector and joint employ a pair of annular gaskets which have outer peripheral surfaces adapted to seat in the gasket-receiving recesses of the bell ends of the fittings, and which have inner diameters substantially equal to the outer diameter of the sleeve, and which have a back seating surface which seats against the raised portion of the gasket. The connector and gaskets are inserted between the bell ends and will extend into the bell ends when the joint is drawn up, with the gaskets seating in the gasket-receiving recesses in the bell ends and against the raised portions of the connector flange.
