Abstract
válvula de segurança para gás (1) compreendendo: um corpo de válvula (2) que define um tubo de fluxo (4) e no qual um obturador (5) está localizado, móvel entre uma posição aberta e uma posição fechada para, respectivamente, permitir e impedir o fluxo de gás de operação através do tubo de fluxo (4); primeiro meio de impulso (7) para o obturador (5) na posição fechada; um mecanismo retentor (8) para manter o obturador (5) na posição aberta, cuja liberação pode ser forçado através do meio de liberação de modo a liberar o obturador (5); um elemento de controle (9) móvel entre uma posição travada e uma posição liberada para, respectivamente, impedir e permitir a liberação do mecanismo retentor (8); um primeiro dispositivo atuador (10; 24) para forçar o elemento de controle (9) na direção da posição liberada. o primeiro dispositivo atuador (10; 24) compreende um corpo atuador (12) móvel entre uma posição estática para permitir que o elemento de controle (9) mantenha a posição travada e uma posição operacional para forçar o elemento de controle (9) na direção de sua posição liberada, uma mola retentora (13) para forçar o corpo atuador (12) na direção de uma posição de descanso e uma mola com memória de forma (14) para superar a força da mola retentora (13) e forçar o corpo atuador (12) na direção da posição operacional quando a temperatura da mola com memória de forma (14) está dentro de uma taxa de temperatura predeterminada.
