Abstract

Patente de Invenção: <B>"EQUIPAMENTO DE SEGURANçA PARA BLOQUEIO DE SISTEMAS DE CANALIZAçãO CONDUTOR GáS"<D>. Deve ser provido um equipamento de segurança térmico para o bloqueio de sistemas de canalização condutores de gás, em que o fluxo de gás é impedido pelo equipamento de segurança quando de um aumento da temperatura na região do sistema de canalização condutor de gás, subordinado ao equipamento de segurança, especialmente com posição fechada dos aparelhos de gás conectados. Ademais, o dispêndio de fabricação e o tamanho de construção devem ser mantidos tão reduzidos quanto possível. O equipamento de segurança apresenta uma válvula de reajuste, que impede uma corrente de retorno do sistema de canalização condutor de gás, subordinado ao equipamento de segurança. Ademais, no equipamento de segurança está disposto um elemento sensível a pressão, ativado pela pressão dominante no sistema de canalização subordinado. Esse elemento sensível a pressão está de tal maneira acoplado com uma válvula de fechamento que, quando do aumento da pressão no sistema de canalização subordinado, pela válvula de fechamento é impedido um fluxo de gás para dentro do sistema de canalização subordinado. O equipamento de segurança serve ao bloqueio automático de canalizações de gás quando da ocorrência de um aumento inadmissível de temperatura na região do sistema de canalização subordinado ao equipamento de segurança.
