Document Type and Number:
Japanese Patent JP2014137084
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a pipe joint which suppresses the adhering of a check valve, and can make fluid smoothly flow to a cylindrical part from a connecting part.SOLUTION: In a pipe joint 10, a step 22 is formed by reducing an inside diameter of a connecting part 16 more than an inside diameter of a cylindrical part 12, and a check valve 20 is formed adjacent to the step 22. The check valve 20 comprises: a valving element 20C which protrudes to the connecting part 16 side in a convex shape, and closes a flow passage 14 by line-contacting with a corner 22A of the step 22; an annular plate-shaped part 20A which is fixed to the step 22, and on which the valving element 20C is positioned in the center; and a support part 20B which is arranged at the inner periphery of the plate-shaped part 20A, and serves as a hinge part for supporting the valving element 20C so as to be turnable.
