TRANSLOCATING WEDGE DESIGN FOR PRESSURE-RETAINING SEAL
First Claim
Patent Images
1. A pressure-retaining seal, comprising:
- a generally tubular adapter having first and second adapter ends, the first adapter end configured to mate with pressure-retaining equipment, the second adapter end providing an adapter sloped surface formed thereon;
a generally tubular pressure seal assembly having first and second assembly ends and a longitudinal centerline, the centerline defining an axial direction parallel to the centerline;
the first assembly end providing a seal receptacle for receiving the second adapter end, the second adapter end and the seal receptacle further each providing cooperating abutment surfaces, the cooperating abutment surfaces forming a pressure seal between the second adapter end and the seal receptacle when the second adapter end is received into the seal receptacle; and
a wedge assembly, the wedge assembly configured to engage both the second adapter end and the first assembly end when the second adapter end is received into the seal receptacle, the wedge assembly including at least one wedge having a wedge surface for engagement with the adapter sloped surface;
wherein, when the second adapter end is received into the seal receptacle, translocation of the at least one wedge, as a whole, towards the centerline engages each wedge'"'"'s corresponding wedge surface onto the adapter sloped surface so as to restrain the adapter from axial displacement relative to the seal receptacle.

16. A pressure-retaining seal, comprising:
-
a generally tubular adapter having first and second adapter ends, the first adapter end configured to mate with pressure-retaining equipment, the second adapter end providing an adapter sloped surface formed thereon; a generally tubular pressure seal assembly having first and second assembly ends and a longitudinal centerline; the first assembly end having a first assembly end interior; a seal receptacle formed on the first assembly end interior, the seal receptacle shaped for receiving the second adapter end, the second adapter end and the seal receptacle further each providing cooperating abutment surfaces, the cooperating abutment surfaces forming a pressure seal between the second adapter end and the seal receptacle when the second adapter end is received into the seal receptacle; and a wedge assembly, the wedge assembly configured to engage both the second adapter end and the first assembly end when the second adapter end is received into the seal receptacle, the wedge assembly including at least one wedge surface for sliding contact engagement with the adapter sloped surface; wherein, when the second adapter end is received into the seal receptacle, sliding contact of the at least one wedge surface against the adapter sloped surface compresses the second adapter end into the seal receptacle. - View Dependent Claims (17, 18, 19, 20, 21, 22)
