<p><P>PROBLEM TO BE SOLVED: To provide a swivel pipe joint of a compact and easy-to-assemble simple structure used for connecting crossing pipes, and capable of stably making various fluids flow without a flow rate variation. <P>SOLUTION: This swivel pipe joint is formed by relatively rotatably joining a female joint 10 and a male joint 20. The female joint 10 has a first hole part 13 connecting the male joint 20 and a second hole part 14 communicating with the first hole part in a crossing state. The male joint 20 is formed as a cylindrical base part 22 whose its end part has the length of not closing the second hole part 14 and inserted into the first hole part 13. An annular packing groove 22A for installing a seal ring 30 brought into close contact with an inner peripheral surface of the first hole part 13 and an annular holding groove 22B for installing a slipping-out preventive ring 40 expandable in the radial direction, are formed on the outer periphery of the base part 22. An annular lock groove 13A corresponding to the holding groove 22B and receiving an outer peripheral part of the slipping-out preventive ring 40, is formed on the inner periphery of the first hole part 13. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
