Abstract

"VáLVULA DE RETENçãO". Descreve-se uma válvula de retenção (10), tipicamente com um formato comumente denominado válvula bico-de-pato, compreendendo um corpo (12) de válvula e uma membrana (14) de válvula. O corpo (12) da válvula é genericamente tubular e inclui uma passagem alongada (16) com a entrada (18) e a saída (20) em extremidades opostas. A membrana (14) da válvula é um diafragma com formato genericamente cónico formado integralmente com o corpo (12) da válvula. O diafragma (14) tem um orifício ou abertura retrátil (22) localizada no vértice do cone ou adjacente a ele. O diafragma cónico (14) está orientado com seu vértice apontando a jusante. O material flexível resiliente a partir do qual o diafragma (14) é fabricado assegura que o diafragma (14) em uma condição retraída obstrua ou feche a passagem (22), para impedir que o fluido flua em uma direção inversa, isto é, retorne na direção da entrada. A pressurização do fluido dentro da passagem (22) no lado da entrada (18) do diafragma (14) deflete o diafragma para abrir a abertura (22), de tal modo que o fluido possa fluir através da passagem, somente da entrada (18) para a saída (20). Uma membrana permeável em somente uma direção pode ser fabricada também a partir de uma almofada ou laminado que incorpora muitas dessas válvulas bico-de-pato retráteis de retenção sobre a superfície da almofada ou laminado.
