PURPOSE:To secure the perfect sealing state for pressure at the both edges of a sleeve by installing a ring-shaped sealing member for receiving the face pressure of a piping-side flange over the part ranging from the sleeve edge surface to a body edge surface. CONSTITUTION:A concaved receiving part 5 is formed onto the outer peripheral surface of the installation part 4 onto a body 3 formed at the both edge parts 1a of a sleeve. A sleeve fixing member 6 is allowed to penetrate through the concaved receiving part from the outside of the body. A ring-shaped sealing member 9 is installed onto the part ranging from the sleeve edge surface 1a to the body edge surface 3a. Therefore, the work performance in installing the sleeve can be improved by permitting the division into the fixing performance and the sealing performance of the sleeve 1 for the body 3, and the sealing performance can be improved. |
