Abstract
METODO DE UTILIZACION DE VALVULAS DE SOLENOIDE DE TRES VIAS PARA UN ACCIONADOR DE VALVULA DE AISLAMIENTO DE UN REACTOR NUCLEAR. SE DESCRIBE LA UTILIZACION DE UNA VALVULA DE SOLENOIDE COMO VALVULA PILOTO PARA UN ACCIONADOR DE VALVULA DE AISLAMIENTO QUE ACTUA EN LA MODALIDAD DE CIERRE EN CASO DE FALLO. LAS VALVULAS PILOTO DE LA TECNICA ANTERIOR PREVISTAS PARA ESTA UTILIZACION ERAN PROPENSAS A UN TIPO DE FALLO QUE NO DA LUGAR NECESARIAMENTE AL CIERRE DE LA VALVULA PRINCIPAL DE AISLAMIENTO DEL VAPOR DE AGUA. EN LA PRESENTE INVENCION, LA PRESION NEUMATICA TIENDE A OPONERSE A LA FUERZA DE ABERTURA QUE ES CREADA POR EL SOLENOIDE. EN PARTICULAR, LA ACCION DE LA PRESION SOBRE LA SUPERFICIE EXPUESTA DEL COMPONENTE DE PISTON CREA UNA FUERZA NETA EN LA DIRECCION DE CIERRE. SU APLICACION ES PARA ASEGURAR EL ACCIONAMIENTO DE UNA VALVULA DE AISLAMIENTO DE VAPOR DE AGUA EN UN REACTOR NUCLEAR.
