Abstract

Vanne dont le joint assure l'étanchéité de l'obturateur en position fermée, mais ne fait pas saillie à l'intérieur du passage en position ouverte. Le corps 4 de la vanne contient un obturateur 16 fixé par une vis 17 sur l'arbre pivotant 18. Le corps 4 comporte un revêtement interne élastique 9 terminé aux extrémités par des brides 10 pénétrant dans des renfoncements 11 du corps. Le revêtement 9 comporte une rainure annulaire 12 d'où émerge une couronne 13 qui est de même diamètre interne que la section de passage. Une gorge 15 divise la couronne 13 en lèvres 14 s'appuyant contre l'obturateur 16 pour assurer l'étanchéité.
