Abstract

La présente invention concerne une vanne de décharge comprenant : • un carter (1) destiné à séparer une veine (2) d'un conduit d'évacuation (3), • un support de porte (18) fixable au carter (1), • une porte (38) monté à rotation sur le support (18) entre une position ouverte et une position fermée, • un premier joint d'étanchéité (48) agencé pour être compressé par la porte (38) contre le support (18) en position fermée, pour empêcher du gaz circulant dans la veine (2) d'atteindre le conduit d'évacuation (3) en passant entre la porte (38) et le support de porte (18), et • un deuxième joint d'étanchéité (36) compressé entre le support (18) et le carter (1) pour empêcher du gaz circulant dans la veine (2) de passer entre le carter (1) et le support (18) pour atteindre le conduit d'évacuation (3).
