Abstract
"DISPOSITIVO PARA EVITAR REFLUXO". A presente invenção refere-se a um dispositivo para evitar refluxo (1) que pode ser empregado em uma tubulação de gás ou de líquido (2). O dispositivo para evitar refluxo de acordo com a invenção apresenta um corpo de fechamento (3) construído como corpo oco aberto no lado de escoamento, que entre si e uma contrapeça do corpo de fechamento (4) central limita um canal de passagem (5). Neste caso, o corpo de fechamento (3) pode ser movimentado, através do meio de corrente que flui através do canal de passagem (5), na direção de passagem (Pf 1) de uma posição de fechamento que encosta, vedando, na contrapeça do corpo de fechamento (4), contra a força de reajuste de sua elasticidade própria e/ou estabilidade própria, para uma posição de abertura. O dispositivo para evitar refluxo (1) de acordo com a invenção pode ser fabricado com pouco dispêndio, também com poucos componentes. Neste caso, o dispositivo para evitar refluxo (1) de acordo com a invenção caracteriza se por uma alta potência de fluxo com simultânea baixa perda de pressão.
