Abstract

APARATO, DISPOSITIVO Y METODO PARA ENSAYAR Y VERIFICAR LA PRESION DE AJUSTE EN UNA VALVULA DE CENTRAL NUCLEAR, ESTANDO ACOPLADA LA VALVULA A UNA LUMBRERA DE UNA TUBERIA DE PRESION E INCLUYENDO UN ELEMENTO DE CIERRE MOVIBLE ENTRE POSICIONES LIMITE DE OBTURACION Y APERTURA DE LA LUMBRERA. UNOS MEDIOS CARGADOS POR RESORTE SIRVEN PARA INDUCIR AL ELEMENTO DE CIERRE HACIA SU POSICION LIMITE DE OBTURACION. SE EMPLEA UN DIAFRAGMA EXPANSIBLE QUE, AL INTRODUCIR PRESION DE AIRE EN UNA CAMARA HERMETICA DEFINIDA POR UN EMBOLO MOVIL, EL DIAFRAGMA Y UN ELEMENTO DE BASE, APLICA UNA RAMPA DE FUERZA AL ELEMENTO DE CIERRE EN DIRECCION CONTRARIA A LA DE INDUCCION DE DICHOS MEDIOS CARGADOS POR RESORTE. SE PREVEN MEDIOS PARA CALCULAR LA PRESION DE AJUSTE DE DICHA VALVULA. EL INVENTO ES APLICABLE A LAS VALVULAS DE LAS INSTALACIONES DE CONTENCION DE LAS CENTRALES DE ENERGIA NUCLEAR.
