<p><P>PROBLEM TO BE SOLVED: To easily and inexpensively install a strainer to an inner ring without increasing cost and an installation space. <P>SOLUTION: This pipe joint is composed of a tubular part 6 having a male screw 9 at the external periphery and protruding from a pipe joint body 1, a sealing inner ring 4 having an annular large-diameter part 11a which is bulged to the external diameter side, and a union nut 3 formed with a female screw 18. A seal part S is formed which tightly causes at least either a clearance between the annular large-diameter part 11a of the inner ring 4 and a tube 2A, or a clearance between the external periphery of the tube 2A and the internal periphery 6N of the tubular part 6 to adhere to a clearance between the external peripheral face 4G of the inner ring 4 and the internal periphery 6N of the tubular part 6 by the fastening of the tubular part 6 of the union nut 3 in a state that the end 2a of the fluorine-resin made tube 2A is fitted thereto caused by the screw-progressing of the tubular part to a root side. The strainer 4A acting on a fluid transportation passage 4W is integrally mounted to the inner ring 4. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
