Abstract

VÁLVULAS DE RETENÇÃO DE MUDANÇA DE COR E DETECÇÃO DE PRESSÃO. A presente invenção refere-se a uma válvula de retenção que inclui um alojamento superior que define uma entrada da válvula de retenção e um alojamento inferior com uma porção de suporte e que define uma saída da válvula de retenção. A válvula de retenção inclui ainda uma câmara colocada entre e definida pelos alojamentos superior e inferior para conectar fluidamente a entrada e a saída e um diafragma flexível montado na câmara. O diafragma flexível permite seletivamente o fluxo de fluido em uma primeira direção e evita o refluxo de fluido em uma segunda direção oposta à primeira direção. O diafragma flexível inclui um material de mudança de cor, e quando o diafragma flexível é assentado na porção de suporte e dobrado devido à força do fluido que flui na primeira direção, o diafragma flexível exibe uma mudança de cor.
