Abstract

"VáLVULA DE SEGURANçA INTRìNSECA, SEM FIO". Sistema de válvula de segurança intrínseca que inclui uma válvula piloto acionada piezeletricamente. A válvula piloto piezelétrica opera a uma voltagem substancialmente reduzida, deste modo eliminando a possibilidade de formação de fagulhas devido à conexão e desconexão de elementos comutadores. O sistema de válvula pode ser operado remotamente por um par receptor/transmissor que coopera para gerar uma voltagem de acionamento para a válvula piloto controlada piezeletricamente. A válvula piloto pode, alternativamente, ser controlada pela aplicação de um sinal de fibra ótica.
