Abstract

"VáLVULA". Um conjunto de válvula (100) compreende um corpo de válvula (110) que tem uma passagem de fluxo de fluido (112-114) em comunicação com a cavidade (116) no corpo de válvula, na qual fica disposto um componente de controle de fluxo (118) para fechar ou abrir seletivamente a passagem de fluxo de fluido. Um operador de válvula (150) aciona uma haste (120) ligada ao componente de controle de fluxo por um meio de ligação que permite o movimento axial da haste (120), mas substancialmente nenhum movimento giratório entre a haste (120) e o componente de controle de fluxo (118). O componente de controle de fluxo (118) compreende meios detentores (130) para deter o movimento axial da haste (120) na direção do componente de controle de fluxo (118) de modo a se transmitir a força da haste ao componente de controle de fluxo (118) de modo a se obter uma função de vedação melhor na posição de válvula selecionada. Um meio para mover haste (152) combinado com o acionador de válvula e a haste faz com que a haste (120) gire e se mova em vaivém. O acionador de válvula (150) move seletivamente o componente de controle de fluxo (118) até uma posição de fechamento de fluxo ou até uma posição de abertura de fluxo.
