Abstract

Patente de Invenção: <B>"ATIVADOR DE VáLVULA COM CARACTERìSTICA DE FECHAMENTO DE EMERGêNCIA"<D>. Um ativador de válvula com um fechamento de emergência inclui o fechamento da válvula quando uma pressão de linha detectada estiver fora dos pontos de disparo de pressão elevada e baixa. O ativador pode ser disparado manualmente. O ativador pode ser disparado em caso de incêndio ou, incluindo um solenóide, um disparo pode ser feito com um sinal apropriado. Uma vez dado o sinal, o ativador requer uma regulagem manual. A operação normal, aberta e fechada da válvula coopera com um mecanismo de embreagem que é parte do sistema de disparo. A modalidade preferida do sistema de embreagem é uma mola, ou molas, de torção que permitem normalmente o movimento em uma direção, mas não na outra, a menos que sob a ação do sistema de disparo.
