Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA FABRICACION DE SUPERFICIES HERMETIZANTES EN VALVULAS CON UN ASIENTO HERMETIZANTE CONFIGURADO EN UNA PARTE DE VALVULA MOVIL Y UNA SUPERFICIE DE ASIENTO DE VALVULA CONFIGURADA EN UN CUERPO DE ASIENTO DE VALVULA. ESTAS VALVULAS YA SE TRATAN EN LA ACTUALIDAD, PARA MEJORAR LA CALIDAD SUPERFICIAL DE SUS SUPERFICIES HERMETIZANTES, DE TAL MANERA QUE LA PARTE DE VALVULA MOVIL Y EL CUERPO DEL ASIENTO DE VALVULA SE PONEN EN UN MOVIMIENTO DE ROTACION ENTRE SI, A PRESION, ANTES DEL MONTAJE DE LA VALVULA. SIN EMBARGO LA CALIDAD SUPERFICIAL LOGRADA NO ES SUFICIENTE PARA CONSEGUIR UNA HERMETICIDAD DE LARGA DURACION. EL NUEVO PROCEDIMIENTO Y EL NUEVO DISPOSITIVO DEBEN POSIBILITAR OTRA MEJORA DE LA CALIDAD SUPERFICIAL DE LOS ASIENTOS HERMETIZANTES. SE LOGRA OTRA MEJORA DE LA CALIDAD SUPERFICIAL DE LAS SUPERFICIES HERMETIZANTES PORQUE AL MOVIMIENTO DE ROTACION (59) REALIZADO DURANTE LA ADAPTACION DEL GRUPO DE VALVULA (1) SE SUPERPONE UN MOVIMIENTO DE OSCILACION (60) DE ALTAFRECUENCIA QUE ACTUA PARALELAMENTE CON RESPECTO AL EJE DE ROTACION (6).
