の問題点が有った。Further, after the large diameter portion is formed, when the mold is removed and time passes, the tube bending portion gradually shrinks and does not sufficiently enter the insertion tube, so that heat remains in the large diameter portion. Since it had to be quickly pushed into the insertion tube of the joint while it was there, there were many problems that agile work was required.

First, as shown in FIG. 1, the basic structure of the present invention is generally used in forming a tube joint in which a diameter-expanding deformation portion is formed on a tube and a ring is attached to the outside of the tube to prevent the tube from coming off. While heating the end portion of the fluororesin tube 1 called PFA in the heating source h as shown in FIGS. 2 and 3, the diameter is enlarged using the diameter expanding jig A to form the large diameter deformed portion 1a, The outer peripheral surface is covered with a ring 2 made of a heat-resistant affinity fluororesin such as poly-tetra-fluoro-ethylene having a melting point higher than that of the tube 1 and heated, and both are welded as shown in FIG. Make a dress.

By tightening the ends of the ring 2 and the large-diameter deformed portion 1a tightly against the bottom portion 3a of the groove ring 3, the tube 1 is prevented from coming off and the shoulder portion of the cap nut 6 is tightened. The tube joint of the present invention can be constructed by tightly pressing the intermediate portion of the tube 1 on the inner surface of the tube 7 to the end surface of the insertion tube 5 to form the tube bending portion 1b.

ことなく「増し締め」が可能となる。By thinning the protruding portion 2a of the ring 2, the thinned protruding portion 2a is appropriately loosened when the cap nut 6 is "retightened" due to the aging of the tube bending portion 1b, and the tube large diameter is increased. "Re-tightening" is possible without applying unnecessary external force to the deformable portion 1a.

安定に使用できるといった第1の効果が有る。Since the present invention is configured as described above, it has the following effects. By tightly pressing the tip of the large-diameter deformed portion 1a of the tube 1 into the groove ring 3 of the joint body 4 via the ring 2 by the screw input of the cap nut 6,
The tube 1 becomes stationary and the shoulder portion 7 of the cap nut 6
The tube bending portion 1b can be formed by tightly pressing the outer peripheral surface of the intermediate portion of the tube 1 to the tip of the insertion tube 5 at the peripheral edge of the tube, and the tube is immovable at the peripheral edge of the shoulder 7 of the cap nut 6 and the ring 2. 1 has the first effect that it is air-tight and liquid-tight with respect to the joint body 4, does not pull out from the joint body 4, and can be used stably for a long period of time.

Since the wall thickness is reduced, the thinned protrusion 2a is appropriately loosened and an unnecessary external force is applied to the large-diameter deformed portion 1a of the tube 1 when the cap nut 6 is "retightened" due to the aging of the tube bending portion 1b. It is possible to add the effect that "re-tightening" is possible without the need.
