Abstract
UN DISPOSITIVO DE CONTROL HIDRAULICO (S) TIENE UN CONSUMIDOR HIDRAULICO (V) DOBLE QUE ESTA ASEGURADO MEDIANTE DOS CONDUCTORES DE TRABAJO (4, 5) QUE SE PUEDEN IMPULSAR A PRESION, TAMBIEN TIENE UNA VALVULA DE SUJECCION DE CARGA (H) QUE SE PUEDE MANIPULAR DE FORMA HIDRAULICA EN UNA DIRECCION DE TRABAJO. TAMBIEN DISPONE DE UN CONDUCTOR DE PRESION DE DISTRIBUCION (12) QUE SE IMPULSA LIBREMENTE Y QUE ESTA CONECTADO AL EMPALME DE DISTRIBUCION DE LA VALVULA DE SUJECCION DE LA CARGA. ASI MISMO CONSTA DE UN ESTRANGULADOR VAPORIZADOR (13) COLOCADO DENTRO DEL CONDUCTOR DE PRESION DE DISTRIBUCION (12). EN ESTE DISPOSITIVO DE DISTRIBUCION SE REGULA EL ESTRANGULADOR VAPORIZADOR (13) MEDIANTE EL MOMENTO DE VISCOSIDAD DE LA PRESION EN CASO QUE EL MOVIMIENTO DE CONTROL DE LA VALVULA DE SOPORTE DE CARGA (H, 6) REACCIONE SOBRE UN MOMENTO DE VISCOSIDAD DE LA PRESION REFERIDA AL DESARROLLO DEL CONSUMIDOR HIDRAULICO (V) TENIENDO EN CUENTA LA DEMORA CRITICA DE LA CARGA (F) DEL MOVIMIENTO DE CONTROL INDEPENDIENTE.TAMBIEN DISPONE DE UNA VALVULA (15, 15'', 15'''', 15'''''', 15 ELEVADO IV) QUE DERIVA AL ESTRANGULADOR VAPORIZADOR (13) QUE CONTROLA EL PASO. LA VALVULA IMPIDE LA INFLUENCIA DEL MEDIO DE PRESION MUY FRIO Y UNA EVAPORIZACION DESEADA CON RESPECTO AL CONTROL DE LA VALVULA DE SUJECCION DE LA CARGA Y A SU REGULACION DEL ESTRANGULADOR EVAPORIZADOR GARANTIZANDO EL RAPIDO CONTROL DE LA VALVULA DE LA SUJECCION DE LA CARGA NECESARIO PARA EL MANTENIMIENTO DE LA CARGA, CONCRETAMENTE PARA UNA DESCONEXION SEGURA.
