Abstract
UN DISPOSITIVO DE CONTROL HIDRAULICO CON UN REGULADOR DE CORRIENTE PARA LOS DOS SENTIDOS SITUADOS EN LA TUBERIA DE VACIO DEL TANQUE. EL REGULADOR DE CORRIENTE PRESENTA UN DIAFRAGMA AFORADOR (9) Y UN PRESIONADOR (12) BASCULANTE CON UN EMBOLO REGULADOR. EL EXTREMO DEL EMBOLO ES IMPULSABLE EN LA CAMARA DE CONTROL POR UN PRESIONADOR QUE NO IMPIDE LOS ACCIONAMIENTOS INSTANTANEOS DE LOS HIDROMOTORES IMPULSABLES CONTRA UNA CARGA POR MEDIO DE CONEXIONES INSTANTANEAS. EL EMBOLO REGULADOR PARA EL AJUSTE CONSUME UN VOLUMEN DETERMINADO DE FLUIDO DE PRESION Y SON PRECISAS COSTOSAS CONSTRUCCIONES Y CONEXIONES PARA LAS MEDIDAS. PARA MINIMIZAR LAS CONEXIONES ESPONTANEAS. PARA IMPEDIR LAS CONEXIONES ESPONTANEAS. PARA IMPEDIR LAS CONEXIONES ESPONTANEAS CON APARATOS PEQUEÑOS SE CONFORMA EL EXTREMO DE LOS EMBOLOS REGULADORES QUE ESTA EXPUESTO A LA CARGA DE PRESION COMO ELEMENTO DE CIERRE Y ACTUA COMO ASIENTO DE VALVULA COORDINADO CON UN ASIENTO DE VALVULA PARA CONTENER LA CARGA DE PRESION Y ESTA PREVISTO ENLA TUBERIA DE SALIDA UNOS BLOQUEADORES (A, A'') QUE ALEJAN LA CARGA DE PRESION DEL PASO DEL PRESIONADOR (12) BASCULANTE. EN LA POSICION DE BLOQUEO SE IMPIDE LA CONEXION ESPONTANEA, PORQUE EL ASIENTO DE VALVULA CON EL MIEMBRO DE CIERRE EN EL BASCULADOR OSCILANTE CONTIENE LA CARGA SIN PERDIDA DEL MEDIO DE PRESION Y LOS REGULADORES DE LOS EMBOLOS CONTENIDOS EN LA POSICION DE BLOQUEO PARA EL CONTROL DEL DIAFRAGMA DE REGULACION NO PIERDAN VOLUMEN DEL MEDIO DE PRESION. EL DISPOSITIVO DE CONTROL HIDRAULICO ES APROPIADO PARA LOS MONTAJES SENCILLOS Y CONTROLADOS LIBRES DE ACTUACIONES ESPONTANEAS Y PARA EL CONTROL DE LA ELEVACION DE HIDROMOTORES IMPULSABLES LATERALMENTE.
