Abstract

Dispositivo anular de estanquidad destinado a establecer contacto con una superficie de estanquidad, con autocentrado sobre ésta, en particular para válvulas y llaves de paso que poseen un cuerpo perforado con un conducto axial y un órgano de obturación móvil, del tipo que posee por lo menos dos estructuras de junta anular o anillos de estanquidad y un anillo rígido dispuesto entre dichas estructuras de junta, montándose este conjunto en un alojamiento anular que se extiende radialmente y cuyo fondo esté configurado para recibir ajustadamente dicha primera estructura de junta y asegurar así la estanquidad con el fondo del alojamiento, montándose dicho anillo radialmente ajustado sobre dicha segunda estructura de junta, que, asegura, en posición de obturación, la estanquidad con dicha superficie de estanquidad asociada caracterizado dicho dispositivo porque la primera estructura citada de junta (1) está configurada de modo que presenta una sección transversal elásticamente deformable y porque el citado anillo (2) está montado concéntricamente a dicha primera estructura de junta (1) deformando elásticamente la sección transversal de ésta sobre toda su periferia, para efectuar, bajo el efecto de la deformación elástica, el autocentrado al efectuarse la obturación, una estanquidad entre dicho anillo (2) y dicha primera estructura de junta (1).
