Ball cock with ball plug connected to spindle - has metal seat rings and housing seat rings whose contacting bearing faces are spherical.

摘要

The longitudinal axis of the seat rings runs through the centre point (22) of the plug (7) and forms with the longitudinal axis (3) of the connecting flange (2) an angle equalling the angle of incline of the seat rings (18). The radius of curvature of the housing seat rings (4) equals that of the surface of the plug (7). The seat rings are inherently resilient and each ring preferably comprises two ring parts connected by a lamella plate. USE/ADVANTAGE - Ball cock in which sealing force of seat rings is produced by plug pressing them against housing seat rings producing higher specific pressure and thus better sealing action.
