    • PURPOSE:To prevent the adiabatic performance from deteriorating during a long time use by providing a vacuum meter on a vacuum adiabatic container and detecting a vacuum down in a space formed by an innercontainer and an outer container to operate a vacuum valve. CONSTITUTION:A vacuum meter 16 is fitted near the middle between an outer container and a vacuum valve 6, and when a vacuum down is detected, the vacuum valve 6 is opened by a signal converted from the vacuum meter 16, and a vacuum pump 5 is operated through it to discharge the atmospheric air leaked into a vacuum space formed by the inner and outer containers. After the vacuum is improved to a predetermined value, the vacuum valve 6 is closed. Thereby, a vacuum adiabatic container can perform an automatic operation that a discharge operation is performed when the vacuum is reduced and it is stopped when the predetermined vacuum is attained during a long time use. Thereafter, this action is repeated, thus the adiabatic container can be used under a stable condition at all times.
    • 目的:为了防止绝热性能在长时间使用中通过在真空绝热容器上提供真空计并在由内容器和外容器形成的空间中检测真空来操作真空阀。 构成:真空计16安装在外部容器和真空阀6之间的中部附近,并且当检测到真空下降时,通过从真空计16转换的信号和真空泵5打开真空阀6 通过其操作以排出泄漏到由内部和外部容器形成的真空空间中的大气。 真空度提高到规定值后,关闭真空阀6。 因此,真空绝热容器可以执行自动操作,当真空减少时进行排出操作,并且在长时间使用期间达到预定的真空时停止。 此后,重复该操作,因此绝热容器可以始终在稳定的条件下使用。
