Abstract

DISPOSITIVO DE VALVULA PARA CONTROL DE FLUJO DESTINADO A SU UTILIZACION EN SISTEMAS DE IRRIGACION. CONSTA DE UN PASO (13) DE SECCION CIRCULAR, DOTADO DE UN ESCALON (14) Y PROVISTO DE UN TRAMO DE ENTRADA (15) Y DE UN TRAMO DE SALIDA (16); DE UNA BASE (17) EN FORMA DE ANGULO, QUE SE EXTIENDE ALREDEDOR DE LA PERIFERIA ANULAR DEL CUERPO DE VALVULA A PARTIR DEL ESCALON; DE UN DEFLECTOR (18) EN FORMA DE ANGULO DIRIGIDO DE MANERA INVERTIDA, QUE FORMA LA PARTE ACTIVA DE LA VALVULA; Y DE UN DISCO FLEXIBLE Y ELASTICO DISPUESTO EN EL PASO (13), QUE PUEDE FLEXIONAR BAJO LA ACCION DEL FLUJO DE FLUIDO, INCREMENTANDO DE ESTA MANERA SU EFECTO DE RESTRICCION DE PASO AL AUMENTAR LA PRESION ESTATICA Y DISMINUYENDO SU EFECTO DE RESTRICCION DE PASO AL DISMINUIR LA PRESION ESTATICA, DE MANERA QUE PERMITE MANTENER UN FLUJO SUSTANCIALMENTE CONSTANTE A TRAVES DEL PASO (13) CONTROLADO.
