Abstract

"VáLVULA, ELEMENTO DE VáLVULA, E, MéTODO DE OPERAR UMA VáLVULA". é divulgada uma válvula de controle (20) do tipo esfera com capacidades de fechamento bidirecional. A válvula de esfera incluindo uma entrada (31) e uma saída (32), um elemento esférico (80) e um conjunto de vedação (50). Durante o fechamento da válvula, o elemento esférico, que é montado excentricamente em um eixo (90, 91), gira de forma a se apoiar no conjunto de vedação. Quando fechado, o conjunto de vedação incluindo um alojamento da vedação (521), uma vedação principal (64) e um componente resiliente (70), faz contato com o elemento esférico na vedação principal, enquanto o elemento resiliente solicita a vedação principal em direção ao elemento esférico. O conjunto de vedação inclui adicionalmente um caminho de fluxo secundário (72) entre a vedação principal e o alojamento da vedação, que fica restrito por dois anéis de vedação unidirecionais (60, 60b).
