Abstract
EMBRAGUE DE SEGURIDAD CORRESPONDEINTE A UN SERVOMOTOR DE EFECTO DOBLE. EL SISTEMA SE COMPONE DE UN SERVOMOTOR DE EFECTO DOBLE (1), COMPUESTO, A SU VEZ, DE DOS CAMARAS (I, II) LLENAS DE LIQUIDO A PRESION PROCEDENTE DE UN REGULADOR; DE UNA VALVULA DE VAPOR (7) ACCIONADA POR EL SERVOMOTOR (1); DE TRES EMBRAGUES DE SEGURIDAD (10, 10, 10'''') IDENTICOS, CADA UNO DE LOS CUALES LLEVA UN DISPOSITIVO DE CIERRE (20), UNA VALVULA DE DISTRIBUCION (40) QUE INCLUYE UNA VALVULA DE ACCIONAMIENTO MAGNETICO (54) Y UN DISPOSITIVO SELECTOR (60), Y DE UN CONJUNTO DE TUBERIAS DE DISTRIBUCION DE LIQUIDO QUE ENLAZAN LOS DIFERENTES DISPOSITIVOS DEL SISTEMA. CUANDO EL SISTEMA FUNCIONA NORMALMENTE, EL LIQUIDO DE LA PRIMERA CAMARA (I) ESTA A MAS PRESION QUE EL DE LA SEGUNDA (II) Y LA VALVULA DE ACCIONAMIENTO MAGNETICO (54) SE ENCUENTRA BAJO TENSION. EN ESTAS CONDICIONES EL DISPOSITIVO DE CIERRE (20) ESTA CERRADO Y EL OBTURADOR (6) DE LA VALVULA DE VAPOR TAMBIEN ESTA CERRADO. CUANDO SE DA LA SEÑAL DE SEGURIDAD, EL SISTEMA ACTUA, ABRIENDOSE EL DISPOSITIVO DE CIERRE (20) DE LOS EMBRAGUES DE SEGURIDAD. P
