<p>PURPOSE:To keep a closing condition of a joint opening part for a long time by providing joints having a corrosion resistant joint main body and a corrosion resistant valve body, also providing a connection mechanism, arranging a corrosion resistant movable ring in which first and second magnets are embedded, and also arranging a corrosion resistant fixed which energizes the valve body in a closing direction through the magnets. CONSTITUTION:In a tube joint which has a pair of joints, provided with a corrosion-resistant joint main body 1 and a corrosion-resistant valve body 2, and a connecting mechanism 3 disconnectably connecting the joint, a corrosion resistant joint main body 1 has a valve chamber 11 and a fluid passage 12 connected thereto. The corrosion resistant valve body 2 is movably installed in the valve chamber 11. A through-hole 61 is formed on the valve body 2, while a corrosion resistant movable ring 6 in which a first magnet 7 is embedded is provided therearound. A through-hole 81 is formed on the corrosion resistant movable ring 6, while a second magnet 9 is embedded therearound. A corrosion resistant fixed ring 8 which energizes the valve body 2 in the closing direction through the magnets 7, 9 is provided. It is therefore possible to surely keep the closing condition of the joint opening part.</p> |
