CONNECTING STRUCTURE BETWEEN HIGH-PRESSURE HOSE AND HOSE JOINT OF PRESSURE REGULATOR, AND PRESSURE REGULATOR

摘要

PROBLEM TO BE SOLVED: To provide a connecting structure between a high-pressure hose and a hose joint of a pressure regulator, capable of reducing the possibility of breakage with time while reducing labor hour in connecting operation, and to provide a pressure regulator.;SOLUTION: In the connecting structure of the hose joint 50 for connecting the high-pressure hose to gas inlet flow passages 4a, 4b of the pressure regulator 1, an O-ring 60 is fitted to a second groove 52a of the hose joint 50 including a base shaft portion 51 having a first groove 51a circumferentially formed thereon and a tip seal portion 52 extended from the base shaft portion 51 toward the tip side and having the second groove 52a circumferentially formed thereon. The tip seal portion 52 is inserted to the gas inlet flow passages 4a, 4b of the pressure regulator 1, and a metallic set member 70 or a quick fastener 80 fixed to the pressure regulator 1 is fitted to the first groove 51a.;COPYRIGHT: (C)2013,JPO&INPIT
