Abstract

um sistema de purificação de água doméstica fornecido no presente modelo inclui principalmente: um pré-filtro, um elemento de filtro de membrana de osmose reversa, uma primeira válvula unidirecional e uma segunda válvula unidirecional; um dispositivo de chaveamento usado para conectar ou desconectar uma trajetória de água entre uma saída de água do pré-filtro e uma entrada de água do elemento de filtro da membrana de osmose reversa; um tanque de armazenamento de água tendo uma primeira cavidade usada para acomodar água pura e uma segunda cavidade usada para acomodar água de torneira tratada pelo pré-filtro; uma torneira de água tendo uma entrada de água que se comunica com uma saída de água da segunda válvula unidirecional através de uma trajetória de água; e uma válvula de inversão automática mecânica, usada para conectar uma trajetória de água entre uma segunda porta e uma quarta porta e, entretanto, desconectar uma trajetória de água entre uma terceira porta e a quarta porta; ou desconectar uma trajetória de água entre uma segunda porta e uma quarta porta e, entretanto, conectar uma trajetória de água entre uma terceira porta e a quarta porta, de acordo com uma alteração na pressão de uma primeira porta da válvula de reversão automática mecânica. o sistema de purificação de água doméstico fornecido no presente modelo não só pode reduzir os custos do equipamento, a taxa de falha e o risco de segurança, mas também pode melhorar o conforto de uso de um usuário.
