Abstract[English]
An overpressure valve (1) is disclosed. The overpressure valve (1) is configured as a drain valve assembly (1) for a filter plate (7) within a horizontal filter press. The overpressure valve (1) has a plug (5) provided with an upper collar (5a), a pressure surface (5d), a sealing surface (5e) below the pressure surface (5d), and a plurality of elastomeric webs (5b) extending between the upper collar (5a) and the pressure surface (5d). The webs (5b) are configured to elastically deform or temporarily stretch when the pressure surface (5d) is exposed to pressure and are preferably non-metallic to improve wear performance from abrasion and/or corrosion.[French]
Une vanne de surpression (1) est divulguée. La vanne de surpression (1) est conçue en tant qu'ensemble vanne de vidange (1) destiné à une plaque filtrante (7) à l'intérieur d'un filtre-presse horizontal. La vanne de surpression (1) comporte un bouchon (5) pourvu d'un collier supérieur (5a), d'une surface de pression (5d), d'une surface d'étanchéité (5e) au-dessous de la surface de pression (5d), et d'une pluralité de bandes élastomères (5b) s'étendant entre le collier supérieur (5a) et la surface de pression (5d). Les bandes (5b) sont conçues pour se déformer élastiquement ou s'étirer temporairement lorsque la surface de pression (5d) est exposée à une pression et sont de préférence non métalliques afin d'améliorer les performances d'usure dues à l'abrasion et/ou à la corrosion.
