Abstract

L'invention concerne un joint de tube avec indication de la température comprenant un logement, un élément de transfert de chaleur, un mandrin et une couverture de surface. Un passage d'eau est disposé dans le logement. Une extrémité de l'élément de transfert de chaleur repose dans le passage d'eau, l'autre extrémité étant raccordée à une bande bimétallique en spirale. L'extrémité centrale de la bande bimétallique en spirale est raccordée à l'élément de transfert de chaleur, l'autre extrémité étant dotée d'un pointeur. Le réglage du débit d'eau est réalisé par la rotation de la couverture de surface. En comparaison avec le thermomètre à affichage numérique de l'art antérieur, la déformation tactile d'une bande bimétallique par la température est utilisée pour indiquer la température. Par conséquent, le joint de tube a une structure relativement bon marché et simplifiée.
