A seal assembly for use with valves is described. An example seal assembly includes a first seal (412) and a second seal (414) opposite the first seal. The first and second seals are to sealingly engage a closure member (316) of a valve and a sealing surface opposite the closure member. A spacer ring (416) is disposed between the first and second seals to prevent the first and second seals from contacting each other. Additionally, the spacer ring (416) is sized so that the spacer ring does not contact the closure member or the sealing surface.
L'invention porte sur un ensemble d'étanchéité destiné à être utilisé avec des soupapes. Un exemple d'ensemble d'étanchéité comprend un premier joint d'étanchéité (412) et un second joint d'étanchéité (414) opposé au premier joint d'étanchéité. Les premier et second joints d'étanchéité viennent en prise de manière étanche avec un élément de fermeture (316) d'une soupape et une surface d'étanchéité opposée de l'élément de fermeture. Une bague d'espacement (416) est disposée entre les premier et second joint d'étanchéité pour empêcher les premier et second joints d'étanchéité de venir en contact entre eux. De plus, la bague d'espacement (416) est dimensionnée de telle sorte qu'elle ne vient pas en contact avec l'élément de fermeture ou la surface d'étanchéité.
