Abstract:
A wellhead pressure control fitting includes a plurality of locks to engage a mating surface of an adapter sealingly seated in a receptacle. The locks each comprise a sensor arranged to measure an amount of movement or rotation of each lock so that full closure of each lock against the adapter is determinable.

Claim (Index 19):
A wellhead pressure control fitting, comprising:\n a generally tubular Pressure Control Equipment (PCE) adapter having first and second adapter ends, the first adapter end configured to mate with pressure control equipment, the adapter providing an annular adapter rib distal from the first adapter end towards the second adapter end; a generally tubular pressure control assembly having first and second assembly ends and a longitudinal centerline, the centerline defining axial displacement parallel to the centerline and radial displacement perpendicular to the centerline, the first assembly end providing a first assembly end interior, the second assembly end configured to mate with a wellhead; the first assembly end interior providing a PCE receptacle for receiving the second adapter end, the second adapter end and the PCE receptacle further each providing cooperating abutment surfaces, the cooperating abutment surfaces forming a pressure seal between the second adapter end and the PCE receptacle when the second adapter end is received into the PCE receptacle; the first assembly end interior further providing a wedge assembly, the wedge assembly including: a plurality of wedges, each wedge having first and second opposing wedge sides, each first wedge side providing protruding top and bottom wedge ribs; a generally hollow wedge receptacle, the wedge receptacle further providing a plurality of shaped wedge receptacle recesses formed in an interior thereof, one wedge receptacle recess for each wedge, the wedge receptacle further having first and second opposing wedge receptacle sides in which the wedge receptacle recesses define the first wedge receptacle side; and wherein each wedge is received into a corresponding wedge receptacle recess so that the first wedge receptacle side and the second wedge sides provide opposing sloped wedge surfaces, wherein axial displacement of the upper receptacle relative to the wedges causes corresponding radial displacement of the wedges; and wherein, as the second adapter end enters the PCE receptacle and engages the cooperating abutment surfaces, axial displacement of the wedge receptacle relative to the wedges causes corresponding radial constriction of the top and bottom wedge ribs around the adapter rib, which in turn restrains the adapter from axial displacement relative to the PCE receptacle; and a sensor arranged to measure a parameter related to an amount of engagement of the wedges with the wedge receptacle.
