Screw fitting attached to valve nozzle, has peripheral bead which is inwardly engaged with threaded ring by projecting collar, so as to transmit tensile strength of screw ring on fitting

摘要

The fitting (10) has a peripheral bead (18) which is radially inwardly engaged with threaded ring (12) by projecting collar (16), so as to transmit tensile strength of the screw ring on the fitting. The threaded ring is divided into two ring portions (20) which are spaced apart from each other. A sleeve (30) is inserted into a receiving opening (26), so as to serve as an anchoring element (28).
