Abstract

VALVULA DE VENTILACION PARA EL CIERRE DE UN MECANISMO DE ACCIONAMIENTO DE BARRA DE CONTROL INSTALADO EN UN REACTOR NUCLEAR. SE COMPONE DE DOS ASIENTOS CONICOS (44, 70), ENTRE LOS QUE QUEDA ALOJADA UNA BOLA AUTOCENTRABLE (66), PERMITIENDO EL MOVIMIENTO DE ESTA EVACUAR EL AIRE QUE QUEDA RETENIDO EN LAS PARTES SUPERIORES DEL RECIPIENTE DE SEGURIDAD DEL REACTOR QUE EL PROCESO DE LLENADO, Y FACILITAR LA ENTRADA DEL AIRE DURANTE EL REAPROVISIONAMIENTO.
