1) Uma v\u00e1lvula redutora de press\u00e3o proporcional \u00e9 uma v\u00e1lvula autom\u00e1tica que reduz a press\u00e3o de entrada para a press\u00e3o de sa\u00edda numa rela\u00e7\u00e3o fixa atrav\u00e9s de um ajuste mec\u00e2nico proporcional.
\n2. a sua fun\u00e7\u00e3o principal \u00e9 estabilizar a press\u00e3o de sa\u00edda, assegurar que a tubagem ou o equipamento a jusante funciona dentro de um intervalo de press\u00e3o seguro
\n3. alcan\u00e7ar o equil\u00edbrio din\u00e2mico da press\u00e3o sem controlo externo
\n4. dete\u00e7\u00e3o de press\u00e3o: A press\u00e3o de sa\u00edda \u00e9 transmitida para a c\u00e2mara superior do diafragma \/ pist\u00e3o atrav\u00e9s da tubula\u00e7\u00e3o de feedback.
\n5) A membrana \u00e9 afetada pelo efeito combinado da press\u00e3o de sa\u00edda e da for\u00e7a da mola.
\n6.equil\u00edbrio din\u00e2mico: Quando a press\u00e3o de sa\u00edda aumenta: o diafragma se move para cima sob press\u00e3o, empurrando o disco da v\u00e1lvula para se mover na dire\u00e7\u00e3o de fechamento, reduzindo a \u00e1rea de fluxo m\u00e9dio e a press\u00e3o de sa\u00edda cai.
\n7. quando a press\u00e3o de sa\u00edda diminui: a for\u00e7a da mola empurra o diafragma para baixo, o disco da v\u00e1lvula abre-se para aumentar a \u00e1rea de fluxo e a press\u00e3o de sa\u00edda aumenta.
\n8. carater\u00edsticas proporcionais: a press\u00e3o de sa\u00edda \u00e9 sempre ajustada de acordo com o r\u00e1cio predefinido (por exemplo, 1\/2 da press\u00e3o de entrada), independentemente das altera\u00e7\u00f5es de caudal.
\n9. estabiliza\u00e7\u00e3o autom\u00e1tica da press\u00e3o: A posi\u00e7\u00e3o do disco da v\u00e1lvula \u00e9 ajustada automaticamente com a flutua\u00e7\u00e3o da press\u00e3o de entrada para manter a press\u00e3o de sa\u00edda est\u00e1vel<\/p>\n

RECURSO<\/h2>\n

1. press\u00e3o constante proporcional: A press\u00e3o de sa\u00edda est\u00e1 numa rela\u00e7\u00e3o fixa com a press\u00e3o de entrada, o que \u00e9 adequado para cen\u00e1rios com grandes flutua\u00e7\u00f5es de press\u00e3o de entrada.
\n2. estrutura simples: Sem energia externa ou dispositivo de controle complexo, contando com ajuste mec\u00e2nico puro, alta confiabilidade.
\n3. design livre de manuten\u00e7\u00e3o: Sem componentes eletr\u00f4nicos, forte resist\u00eancia \u00e0 polui\u00e7\u00e3o, adequado para meios com baixa qualidade da \u00e1gua (como sistemas de \u00e1gua de inc\u00eandio).
\n4. ampla adaptabilidade: Suporta meios l\u00edquidos e gasosos, faixa de propor\u00e7\u00e3o comum 1,5: 1 a 4: 1, press\u00e3o m\u00e1xima de trabalho at\u00e9 PN25.<\/p>\n
