CONNECTION MEMBER
Document Type and Number:
Japanese Patent JP2021025609
Kind Code:
A
Abstract:
To provide a connection member capable of maintaining sufficiently high sealability of a connection part between one fluid equipment and the other even under circumstances that permanent distortion appears in association with repeating heat expansion and shrinkage.SOLUTION: The connection member includes a first member, a second member, and an engagement structure. The first member and the second member displaceable between a closed position and an open position are each formed in an annular shape at the closed position to sandwich a member to be connected and fasten it in the axial direction, and released from the annular shape at the open position to enable the removal of the member to be connected. The engagement structure is installed at the ends of the first and second members in the peripheral direction of the annular shape to make the first and second members into engagement with each other, when at the closed positions. The engagement structure is arranged in a region apart from both edges of the first and second members in the axial direction of the annular shape.SELECTED DRAWING: Figure 6
