Abstract

UNA VALVULA REGULADORA DE FLUJO MODULADO A PRESION (13) PARA UTILIZAR EN SISTEMAS DE IRRIGACION TIENE UN PIVOTE ELASTOMERICO UNITARIO (24) PARA DEFINIR AL MENOS UN PASO DE FLUJO (32) Y UN DIAFRAGMA FLEXIBLE (35) SUPERPUESTO AL ANTERIOR, ADYACENTE A LA ENTRADA DE LA VALVULA. EN FUNCIONAMIENTO, EL DIAFRAGMA (25) ES EXPUESTO A LA PRESION DEL AGUA QUE PREVALECE EN LA ENTRADA DE LA VALVULA (13) PARA DOBLARSE HACIA DENTRO Y VARIAR EL TAMAÑO DEL PASO (32) PARA REGULAR Y MODULAR EN CAUDAL A TRAVES DEL MISMO. EL DIAFRAGMA FUNCIONA PARA MANTENER UN MICRO-CAUDAL A TRAVES CASI CONSTANTE EN EL CONDUCTO, POR EJEMPLO SELECCIONADO DE ENTRE LOS LIMITES GLOBALES MAXIMOS DE 2 Y 6 GPH (7,6 A 227 L/H). EL VASTAGO (24) ES INTERCAMBIABLE EN UN ALOJAMIENTO (20) DE LA VALVULA REGULADORA PARA QUE TENGA LUGAR EL CAUDAL CASI CONSTANTE Y ESTA PARTICULARMENTE ADAPTADO PARA UTILIZAR EN SISTEMAS MODULADOS DE PRESION DE IRRIGACION POR GOTEO, EN EL CUAL EL AGUA ES ALIMENTADA A TRAVES DE LA VALVULA A UN DISPOSITIVO DISTRIBUIDOR DE AGUA, COMO UN NEBULIZADOR O UN EMISOR DE GOTAS.
