Claims

[Claims for Utility Model Registration] (1) The joint body into which the pipe to be connected is inserted is formed with a tapered inner surface whose diameter decreases toward the back, and an elastic material is formed between the tapered inner surface and the outer surface of the pipe. A packing type pipe joint in which a packing formed in an annular shape is attached, and a pressing member that presses the packing toward the inner side is engaged with the joint main body, wherein a surface of the packing opposite to the outer surface of the pipe and a A packing type pipe joint characterized in that a plurality of protrusions are formed in the circumferential direction on each of the surfaces facing the tapered inner surface of the joint body. (2) Form a tapered inner surface that decreases in diameter toward the back of the joint body into which the pipe to be connected is inserted, and form a parallel hole in the joint body on the inlet side of the tapered inner surface, and connect these tapered inner surfaces and the parallel holes. In the packing type pipe joint, a packing formed in an annular shape made of an elastic material is attached between the outer surface of the pipe, and a pressing member that presses the packing toward the inner side is engaged with the joint main body, A plurality of circumferential protrusions are formed on a surface of the packing that faces the outer surface of the pipe, and circumferential protrusions are formed on each of the surface that faces the tapered inner surface of the joint body and the surface that faces the parallel hole. This is a packing type pipe joint that is characterized by the following.
