Features for protecting fastener clamping loads on metal seals

The invention relates to a feature for protecting fastener clamping loads on a metal seal. A block fitting assembly includes a first block, a second block, and a first sealing element disposed between the first block and the second block. The clamping device exerts a clamping force for compressing the first sealing element between the first block and the second block in the axial direction of the block fitting assembly. The first heel structure protrudes axially from one of the first block or the second block and toward the other of the first block or the second block. The first heel structure is configured to be spaced apart from or in contact with the other of the first block or the second block depending on a temperature of the first block. 本发明涉及一种用于保护金属密封件上的紧固件夹紧载荷的特征。一种块配装件组件，其包括第一块状件、第二块状件以及设置在第一块状件与第二块状件之间的第一密封元件。夹紧装置施加用于将第一块状件与第二块状件之间的第一密封元件沿块配装件组件的轴向方向压缩的夹紧力。第一跟部结构从第一块状件或第二块状件中的一者轴向地突出并且朝向第一块状件或第二块状件中的另一者突出。第一跟部结构构造成根据第一块状件的温度与第一块状件或第二块状件中的另一者间隔开或接触。
