Abstract

"VáLVULA EM PROFUNDIDADE E PROCESSOS CORRELACIONADOS". Sob amplo aspecto, a presente invenção é um multiplexador hidráulico em profundidade, que é compreendido de uma ou mais válvulas de transição pilotadas (14) e processo de uso. A invenção toma um ou mais sinais de entrada de um painel de controle de superfície ou computador (86), os ditos sinais podem ser elétricos ou hidráulicos, e converte os sinais em uma pluralidade de canais de saída hidráulicos. A invenção é mostrada em uma variedade de modalidades preferidas, incluindo uma versão desenvolvida em tubulação, uma versão recuperável por cabos, e uma versão residindo na parede de um equipamento de acabamento em profundidade. Também relatado é o uso de múltiplas válvulas de transição usadas em paralelo ou em séries para englobarem um multiplexador de fluido hidráulico em profundidade, controlável por e reportando posições das ditas válvulas de transição ao painel de controle de superfície ou computador.
