Abstract
Patente de Invenção para <B>"VáLVULA REGULADORA"<D>. Uma válvula reguladora compreendendo um obturador regulador (3), que coopera com uma sede de válvula (2,5,6), tendo uma gaxeta substancialmente anular (5) que, quando o obturador regulador (3) está na posição de fechamento, adere com uma certa força compressiva, transversal à direção de fluxo, contra a borda terminal periférica do obturador regulador (3). De acordo com a invenção, pelo menos uma parte da força compressiva que age entre a gaxeta (5) e a borda terminal do obturador (3) é exercida pela pressão hidrostática do fluido interceptado quando a válvula está na condição de fechamento. A gaxeta (5) apresenta superfícies de compressão (605), em uma posição radialmente externa com relação à superfície que contacta a borda terminal periférica do obturador (3), girada oposta à superfície de contato entre a gaxeta (5) e o obturador (3), e sendo orientada de tal modo que pelo menos um de seus componentes direcionais é paralelo ao fluxo, de modo a gerar uma compressão perpendicular ao fluxo. Referidas superfícies (605) são accessíveis e expostas ao fluido interceptado.
