Claims

[Claims for Utility Model Registration] 1. A valve body 4 which is movable in the longitudinal direction of the joint body 1 and is biased from the primary side to the secondary side, inside the joint body 1, and the valve body 4. A sealing member 14 that closes the flow path in the joint body 1 by contacting the joint body 1,
A pipe joint configured such that the valve body 4 in contact with the sealing member 14 is moved by a pipe 19 connected to the secondary side of the joint body 1 to open the flow path. A stop member 10 for restricting movement of the valve body 4 toward the secondary side is fixed to the inner surface of the ring-shaped seal member 14 that contacts the seal surface 6a of the valve body 4. The diameter of the inner surface 14a gradually increases from the primary side to the secondary side, and the diameter of the secondary side is larger than the outer diameter of the pipe 19 connected to the secondary side of the joint body 1, A pipe joint characterized in that the diameter of the primary side is smaller than the outer diameter of the pipe 19, and the pipe 19 is sealed by the sealing member 14. 2. The pipe joint according to claim 1, wherein the inner surface 14a of the sealing member 14 has a substantially truncated conical side surface shape whose diameter increases from the primary side to the secondary side. 3. A pipe joint according to claim 1, wherein said sealing member 14 has a ring-shaped lip on its inner edge, and is adapted to seal by this lip. 4. The pipe joint according to claim 1, wherein the sealing surface 6a of the valve body 4 has a substantially truncated conical side surface shape whose diameter decreases from the primary side to the secondary side. 5 The stop member 10 has a ring shape with a portion cut out, and one of the end surfaces 12 and 13 thereof faces inward with respect to the radius, and the other end face 13 faces outward with respect to the radius. Claim 1
4. The pipe joint according to any one of 4 to 4. 6 Three support protrusions 7 are provided at the end of the secondary side of the valve body 4, and these support protrusions 7 come into contact with the tip of the pipe 19 connected to the secondary side of the joint body 1. The pipe joint according to any one of claims 1 to 5. 7. The pipe joint according to claim 4, wherein the secondary end of the sealing surface 6a of the valve body 4 is rounded into a substantially arc shape.
