<p><P>PROBLEM TO BE SOLVED: To provide a pipe fitting with a valve reduced in pressure loss, having sufficient strength, and reduced in manufacturing cost. <P>SOLUTION: A valve 30 having a head part 31 and a shaft part 32, a valve supporter A fixed to cylindrical bodies 11 and 21 and supporting the shaft part 32 freely to move in the axial direction, and an energizing member 8 for energizing the head part 31 are provided in flow paths L1 and L2 of the cylindrical bodies 11 and 21. In the state of removing fitting, the head part 31 is energized and abuts on contracted diameter parts 12 and 22 so as to close the flow paths L1 and L2, and in the state of fitting, both the head parts 31 are separated from the contracted diameter parts 12 and 22 by pushing of both the head parts 31 to each other, and both the flow paths L1 and L2 are communicated with each other. The valve supporter A has an axial part A1 surrounding the shaft part 32 along the peripheral surface of the shaft part 32, stretched parts A2 extending from both end parts A1a of the axial part A1 to the inner peripheral surface 11a, and base parts A3 respectively connected to a tip part A2a of the stretched part A2 and formed along the inner peripheral surface 11a. Further, the axial part A1, the stretched part A2 and the base part A3 are respectively formed into a plate shape thin in the cross section of the flow paths L1 and L2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
