<p><P>PROBLEM TO BE SOLVED: To provide a pipe joint with a valve comprising a nose and a body, having reduced pressure loss while suppressing the breakage of a seal material. <P>SOLUTION: The body 32 includes a recessed insertion portion 50 into which the nose 12 is inserted. The nose 12 includes a moving valve 14, and the recessed insertion portion 50 includes a moving valve 34. The moving valves 14, 34 have seal members 26, 44, respectively, and the seal members 26, 44 have straightening members 20, 48 on the corner sides, respectively. The straightening members 20, 48 have inclined faces 20 B, 48B whose diameters are enlarged toward the inlet sides and protruded portions 20C, 48C at the front ends of the inclined faces 20B, 48B, respectively. The maximum radii of the outer peripheral faces of the protruded portions 20C, 48C are set to be -5% to +5% of the maximum radii of the outer peripheral faces of the seal members 26, 48. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
