Abstract

"SISTEMA DE ABASTECIMENTO DE áGUA, VáLVULA DE CONTROLE DIFERENCIAL, E, MéTODO PARA CONTROLAR PRESSãO EM UM SISTEMA DE ABASTECIMENTO DE áGUA". é descrito um sistema de abastecimento de água que compreende uma linha de abastecimento e uma rede de consumidores, um dos quais sendo um consumidor monitorado que recebe o nível mínimo de pressão, um sistema de regulagem de pressão que compreende uma válvula de redução de pressão (PRV) associada com uma válvula piloto pré-ajustada em uma pressão de saída nominal e um sistema de controle de pressão que compreende uma válvula de controle diferencial (DCV). Uma unidade de amostragem é provida para medir um parâmetro de fluxo indicativo da pressão no consumidor monitorado e que emite um sinal de pressão a um controlador que, por sua vez, gera um sinal de controle em resposta ao sinal de pressão para ativar um atuador da DCV, governando assim a vazão pela DCV, de maneira a se obter a pressão desejada no consumidor monitorado, independente de alteração da vazão na PRV.
