封止構造及びそれを備えた圧力容器
Document Type and Number:
Japanese Patent JP7426249
Kind Code:
B2
Abstract:
To provide simpler pressure relief means that does not require a movable part.SOLUTION: A sealing structure 4 comprises at least one pressure relief flow path, an evacuation space 41, a sealing member 42, and a communication flow path 43. The communication flow path is provided so as to be able to communicate with a space to be sealed 5, the pressure relief flow path and the evacuation space. The sealing member is provided so as to always seal the communication flow path and to be deformable when the pressure in the space to be sealed is abnormally increased. When the sealing member is deformed by the abnormal pressure rise, the sealing member moves to the evacuation space, so that the space to be sealed and the pressure relief flow path communicate with each other through the communication flow path.SELECTED DRAWING: Figure 2
