\u00a0 V\u00e1lvula de v\u00e1cuo e liberta\u00e7\u00e3o de ar de orif\u00edcio duplo Hivent que combina as fun\u00e7\u00f5es de orif\u00edcio grande e pequeno numa s\u00f3 unidade, o orif\u00edcio grande permite que o ar seja expulso do sistema durante o enchimento de uma tubagem e admite ar de volta ao sistema quando ocorre press\u00e3o subatmosf\u00e9rica.<\/p>\n

Em caso de press\u00e3o subatmosf\u00e9rica no sistema, o n\u00edvel da \u00e1gua desce, fazendo com que o flutuador caia do seu assento e permita a entrada de ar.<\/p>\n

Durante o funcionamento normal do coletor, o pequeno orif\u00edcio liberta o ar que se acumula sob press\u00e3o. Com o coletor em funcionamento, o flutuador est\u00e1 normalmente encostado ao seu assento. \u00c0 medida que o ar entra no corpo da c\u00e2mara, o n\u00edvel da \u00e1gua vai baixando at\u00e9 se atingir um n\u00edvel em que o flutuador desce do seu assento, o que permite a sa\u00edda do ar.<\/p>\n

Flutuador e guia de flutuador em ABS, parafusos A4, revestimento 300 \u00b5, DN50-200<\/p>\n

V\u00e1lvula de al\u00edvio de ar para \u00e1gua pot\u00e1vel (n\u00e3o para \u00e1guas residuais) e l\u00edquidos neutros m\u00e1x. 70\u00b0 C<\/p>\n

As v\u00e1lvulas de ar de duplo orif\u00edcio e tripla a\u00e7\u00e3o foram concebidas para o enchimento r\u00e1pido e autom\u00e1tico de tubagens e para a drenagem de tubagens, bem como para a descarga autom\u00e1tica do ar acumulado em condi\u00e7\u00f5es normais de trabalho. O design \u00fanico \"Aerocin\u00e9tico\", em que o ar que sai do sistema n\u00e3o pode for\u00e7ar o flutuador para cima e fech\u00e1-lo prematuramente, garante que a v\u00e1lvula s\u00f3 se fecha depois de todo o ar ter sa\u00eddo do sistema e a \u00e1gua ter entrado na c\u00e2mara. Todos os componentes de ferro d\u00factil s\u00e3o revestidos com ep\u00f3xi ligado por fus\u00e3o aprovado pela GSK para garantir uma elevada durabilidade. Todos os outros componentes s\u00e3o fabricados com um material polim\u00e9rico aprovado pela WRAS ou com a\u00e7o inoxid\u00e1vel para minimizar o risco de corros\u00e3o. Todos os vedantes s\u00e3o feitos de borracha EPDM aprovada pela WRAS, com um excelente conjunto de compress\u00e3o e capacidade de recuperar a sua forma original.<\/p>\n

 <\/p>\n

Carater\u00edsticas<\/p>\n

Um design inteligente do flutuador impede que o ar que sai do sistema feche prematuramente a v\u00e1lvula<\/p>\n

Grande capacidade de caudal de ar<\/p>\n

Todas as pe\u00e7as de ferro em contacto com a \u00e1gua s\u00e3o revestidas com ep\u00f3xi de fus\u00e3o aprovado para \u00e1gua pot\u00e1vel<\/p>\n

Os vedantes resilientes s\u00e3o feitos de borracha EPDM e o assento \u00e9 em ABS, todos aprovados para \u00e1gua pot\u00e1vel<\/p>\n

Todas as outras pe\u00e7as internas s\u00e3o de a\u00e7o inoxid\u00e1vel AISI 316 altamente resistente \u00e0 corros\u00e3o ou ABS<\/p>\n

Nenhuma pe\u00e7a m\u00f3vel est\u00e1 em contacto com o revestimento interno<\/p>\n
