    • PROBLEM TO BE SOLVED: To provide a valve device for a liquefied gas container exerting sufficient durability even against a surge pressure generated when an over-filling prevention device shuts off the liquefied gas being put in the container. SOLUTION: The valve device 10 for the liquefied gas container is equipped with the over-filling prevention device composed of a float 27 borne approximately in the center p of inside the container, an over-filling preventive valve 30 installed near a filling valve 12 in its downstream, a transmission shaft 25 with one end interlocked with a rotary shaft 28 through an actuation converting means and the other end leading to the position where the over-filling preventive valve 30 is installed, and a valve opening/closing cam 35 coupled with the other end of the transmission shaft and converted rotationally into the open actuation position in which the valve 30 is opened or the close actuation position in which the valve 30 is closed momentarily. This enhances the durability against a high surge pressure generated at the time of filling with the gas, allowing exerting the safety of the container sufficiently. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了提供一种液化气容器的阀装置,即使在过充保护装置关闭放置在容器中的液化气体时产生的浪涌压力也能提供足够的耐久性。 解决方案:用于液化气容器的阀装置10配备有由大致在容器内部中心p附近的浮子27组成的防溢出装置,安装在填充物附近的过充保护阀30 阀12在其下游,传动轴25的一端通过致动转换装置与旋转轴28互锁,另一端通向安装防止过充气阀30的位置,阀开/关凸轮 35,其与传动轴的另一端连接,并被旋转地转换成阀30打开的打开致动位置或阀30暂时闭合的关闭致动位置。 这增强了在填充气体时产生的高浪涌压力的耐久性,从而充分地施加容器的安全性。 版权所有(C)2005,JPO&NCIPI
