Abstract
APARATO DE ALINEACION Y DE RETRACCION DE ANILLO DE ESTANQUEIDAD PARA VALVULA DE TIPO MACHO. UN CONJUNTO DE MACHO DE VALVULA PARA USO EN UNA VALVULA ESTRANGULADORA DE VAPOR INCLUYE UN CUERPO DE VALVULA Y UN ANILLO DE GUIA DESMONTABLE FIJADO A UN EXTREMO DEL CUERPO DE VALVULA. EL ANILLO DE GUIA DEFINE, CON EL CUERPO DE VALVULA, UNA GARGANTA CIRCUNFERENCIAL QUE TIENE PAREDES CON UNA RANURA FORMADA EN UNA PARED DE LA GARGANTA, Y UN ANILLO DE DESGASTE INSERTADO EN LA RANURA. EL ANILLO DE DESGASTE TIENE UNA SUPERFICIE DE APOYO EN ANGULO QUE CONTACTA CON UN ANILLO ESTANCO A LA PRESION Y PRODUCE CIERTA RETRACCION DEL ANILLO ESTANCO A LA PRESION EN RESPUESTA A UN MOVIMIENTO REPENTINO DEL MACHO DE VALVULA.
