Abstract

Patente de Invenção: <B>"CONJUNTO DE VáLVULA DE ALìVIO DE PRESSãO PARA TANQUE DE TRANSPORTE"<D>. Um conjunto válvula de alívio de pressão (10) para liberar fluido através de uma descarga (V) em um vagão tanque ferroviário, caminhões tanque ou vasos similares. Um disco de válvula (16) é deslocado normalmente em uma posição fechada por meio de uma pluralidade de molas de força constante (30) de fitas de aço laminado (30a) sobre tambores (32) suportados em suportes cantoneiras verticais (36) arranjados simetricamente ao redor de um assento de válvula (14). A pressão na qual a válvula se abre é determinada por meio de uma pré-seleção do número de molas
