Abstract

LA VALVULA COMPRENDE UNA MARIPOSA (11) COOPERANDO CON UN ASIENTO (12) Y UN RESORTE (13)TENDENTE A APLICAR LA MARIPOSA SOBRE EL ASIENTO A FIN DE LIMITAR EL CAUDAL DE PASO DE UN FLUIDO HIDRAULICO A TRAVES DE LA VALVULA. PARA HACER VARIAR LA FUERZA EJERCIDA POR EL RESORTE (13) SOBRE LA MARIPOSA (11) EN FUNCION DEL CAUDAL QUE ATRAVIESA LA VALVULA, ESTA COMPRENDE UN PISTON MOVIL (14) SOBRE EL CUAL VIENE A APOYARSE EL RESORTE (13), EL PISTON MOVIL SE DESPLAZA EN UN CILINDRO (15) QUE SEPARA DOS CAMARAS (15A,15B). UNA DE ESTAS CAMARAS ESTA EN COMUNICACION CON EL FLUIDO HIDRAULICO MAS ABAJO O MAS ARRIBA DE LA VALVULA, LA OTRA CAMARA ESTA EN COMUNICACION CON UN ESPACIO INTERMEDIO (23) EN EL CUAL LA MARIPOSA (11) CONSTITUYE UN PRIMER ORIFICIO DE PASO Y QUE ESTA PROVISTO, CON UN SEGUNDO ORIFICIO DE PASO (24), DE UNA RESTRICCION (25) QUE DEFINE UNA CAIDA DE PRESION CRECIENTE CON EL CAUDAL QUE LA ATRAVIESA.
