Abstract

SE DESCUBRE UN APARATO DE CONTROL DE PRESION PARA SUMINISTRO FLUIDO PARA USAR EN CONJUNCION CON UNA VALVULA (10) DE CONTROL DE PRESION DE UN SISTEMA DE SUMINISTRO FLUIDO, EL CUAL INCLUYE: PRIMEROS MEDIOS SENSORES (26,28) PARA DETECTAR LA PRESION DEL FLUIDO EN UN PRIMER PUNTO (12,14) DEL SISTEMA, Y PRIMEROS MEDIOS DE CONTROL (16) PARA CONTROLAR LA VALVULA (10) DE CONTROL DE PRESION, PARA AJUSTAR LA PRESION DEL FLUIDO EN EL PRIMER PUNTO DEL SISTEMA DE ACUERDO CON UNA DIFERENCIA ENTRE LA PRESION DEL SENSOR DE LOS PRIMEROS MEDIOS Y UNA PRESION DE VALVULA PREDETERMINADA. EL APARATO ADEMAS INCLUYE SEGUNDOS MEDIOS DE CONTROL (24) PARA CONTROLAR EL VALOR DE PRESION PREDETERMINADO PARA REDUCIR FLUCTUACIONES EN LA PRESION DEL FLUIDO EN UN SEGUNDO PUNTO DEL SISTEMA. EL FIN DE ESTE APARATO ES MANTENER LA MENOR PRESION POSIBLE EN LAS TUBERIAS DE SUMINISTRO QUE SEA ADECUADA CON EL MANTENIMIENTO DE UNA PRESION RAZONABLE EN AREAS ELEVADAS Y SALIENTES Y CONVENIENTE A LA DEMANDA DE AGUA. ESTO PROVEE UNOS MEDIOS DE CONTROL DE PRESION DE SUMINISTRO DE AGUA CON LO CUAL ES POSIBLE REDUCIR SUSTANCIALMENTE LA PERDIDA DE AGUA A TRAVES DE GOTERAS.
