Abstract

Una válvula antisifón (6) para líneas de infusión de aplicaciones médicas y similares, que comprende un primer conector tubular (2) y un segundo conector tubular (3), que definen, respectivamente, un pasaje corriente arriba (4) y un pasaje corriente abajo (5) que son coaxiales entre sí, y entre los cuales se dispone transversalmente un diafragma (8) fabricado de un material deformable elásticamente y que coopera de forma estanca a los fluidos con un asiento de válvula anular (11) de dicho primer elemento tubular (2) para mantener dicha válvula antisifón (6) normalmente cerrada, en la cual una presión predeterminada del fluido en dicho pasaje corriente arriba (4) origina una curvatura de dicho diafragma (8) y la abertura de dicha válvula antisifón (6), caracterizada porque dicho asiento (11) de válvula anular está definido por una pared cónica superficial de dicho primer elemento tubular (2), que diverge hacia dicho segundo elemento tubular (3), y porque dicho diafragma consta de la pared inferior (8) de un elemento con forma de copa (7), el borde (8a) periférico externo del mismo se mantiene normalmente presionado en contacto estanco a los fluidos contra el asiento de válvula anular (11) bajo el empuje axial ejercido por la pared lateral (9) de dicho elemento de copa (7); la curvatura de dicha pared inferior (8) del elemento de copa (7) producida, en uso, por dicha presión de fluido predeterminada origina la contracción radial de dicho borde periférico externo (8a) y su separación consecuente de dicho asiento de válvula anular (11).
