Abstract
"VáLVULA DE SEGURANçA EXCêNTRICA DESUBSUPERFìCIE PARA CONTROLE DO FLUXO DE FLUIDO EMUM CONDUTO DE POçO". Válvula de segurança excêntrica desubsuperfície que inclui um membro (12) de corpo excêntricoapresentando um lado espesso, um lado delgado, e um furo (14)longitudinal através do mesmo. Uma alheta (36) curvada éinstalada no interior do membro de corpo para controle doescoamento de fluido através do furo longitudinal, e é móvel entreuma posição fechada e aberta. Esta alheta (36) pode ser dispostadentro de um recesso (40) no lado espesso do membro de corpoexcêntrico quando em sua posição aberta. Um tubo (16) deescoamento é disposto no interior do membro (12) de corpo esendo desviável de forma remota em resposta ao movimento de umpistão (18). Pelo menos uma mola de retorno (48) e/ou um volumecontido de gás pressurizado é se fornecido para solicitação dotubo (16) para além da alheta (36). O pistão (18) pode serconectado junto a uma placa (28) excêntrica disposta de formadeslizável em torno do tubo (18) e entre um primeiro e segundoressaltos no tubo (16). Uma mola (34) de deslizamento é dispostaem torno do tubo (16) e entre a placa (28) excêntrica e um dosprimeiro e segundo ressaltos de tubo para a absorção das forçasconferidas ao tubo pela alheta diante do fechamento.
