Abstract

''VáLVULA DE ISOLAMENTO DUPLO'' Uma válvula de isolamento duplo (10) que compreende: um corpo de válvula (12) com orifícios de entrada (14) e de saída (40) opostos que definem uma cavidade interna; um primeiro membro de válvula (22); e um segundo membro de válvula (34). Os membros de válvula (22, 34) (de preferência tampões) apresentam primeiras extremidades mais estreitas (22a,34a) e segundas extremidades mais largas (22b,34b) e são rotativamente montados dentro da cavidade do corpo de válvula para rotação em torno de um primeiro e segundo eixo geométrico de rotação substancialmente perpendicular ao eixo geométrico de fluxo <B>F<D> definido pelos orofícios de entrada e saída (40). Os membros de válvula incluem passagens de fluxo substancialmente retangulares (24,36). As primeiras extremidades dos membros de válvula se estendem além das segundas extremidades ao longo dos primeiro e segundo eixos geométricos de rotação em direções opostas, e os membros de válvula são rotacionáveis entre uma posição aberta, na qual as passagens de fluxo (24,36) são orientadas para estarem genericamente alinhadas com e localizadas no eixo geométrico de fluxo <B>F<D> para habilitar o fluido que ingressa pelo orifício de entrada a passar através da passagem de fluxo e uma posição fechada, na qual as passagens de fluxo (24,36) são orientadas para serem genericamente perpendiculares ao eixo geométrico de fluxo <B>F<D> para prevenir que o fluido ingressando pelo orifício de entrada passe através da passagem de fluxo. Nesta configuração, o fluxo de fluido através da válvula pode ser perturbado menos do que com as válvula de isolamento duplo da técnica anteriormente existente enquanto permitindo fluxo extensivo através da válvula.
