<p>PURPOSE:To provide a piping joint where an excessive force is not applied to a connecting part even when minor dislocation or misalignment due to thermal expansion are generated and there is flexibility in the movement of the joint. CONSTITUTION:In a piping joint 10, an inner basin 12 made of crystal or glass is provided in an outer basin 11 made of a normal material such as plastics, and the liquid or the gas is fed into the inner basin through the wall of the outer basin 11. A hole 111 is provided in the wall of the outer basin 11, and a flange part 201 of a block 20 where the flange is provided and a through hole 30 is provided to another member 22 fixed inside of the block is fixed to this hole 111. Spherical parts 241, 242 are provided to the respective ends inside the through holes 30, one of the spherical part 241 of a connecting member 24 having a passage 243 therein is inserted, and the spherical surface is brought into contact with the inner circumferential surface of the through-hole 30. Then, a suppressing member 23 to suppress the spherical part 241 in a rotatable manner is fixed to the block 20. The other spherical part 242 of the connecting member 24 is inserted into the inner basin 12 so as to be brought into contact with the inner circumferential surface of a circular hole part 17.</p> |
