Abstract

VALVULA LIMITADORA DE PRESION CON PRESION DE DESCARGA CONSTANTE. CONSTA DE UN CIERRE DE CHAPALETA CON UNA BOLA (42) QUE PRESIONA SOBRE UN ASIENTO DE VALVULA (40) AL SER EMPUJADA POR UN MUELLE (52) A TRAVES DE UN CILINDRO (32). ESTE CILINDRO, PROVISTO DE UNA JUNTA TOROIDAL ESTANCA (34) POSEE UNOS PASOS DE ESTRANGULAMIENTO (54) QUE DESCARGAN FLUIDO DESDE EL LADO DE ALTA PRESION (12) AL DE BAJA PRESION (20) POR INTERMEDIO DE UNA CAMARA (24). EL FONDO DE LA VALVULA (28) TIENE UN VASTAGO CENTRAL (50) QUE SIRVE DE TOPE AL CILINDRO (32) EN SU DESPLAZAMIENTO. DE ESTA FORMA, LA SECCION LIBRE ES CONSTANTE SEA CUAL SEA EL DESPLAZAMIENTO DE LA BOLA.
