Abstract
The invention relates to the sealing of detachable joints of the pipelines and manifolds by using metal elastic gaskets. A detachable stationary sealing device comprises the flanges having sealing surfaces, being tapered for one of the flanges and concave for another, a sealing gasket and a retaining releasing ring. The gasket is provided with elastic tabs being in contact with the sealing surfaces of the flanges, and an annular projection, the inner cylindrical surface of which is in contact with the outer cylindrical surface. The retaining releasing ring is of C-shaped cross-section and is fixed in the annular groove made on said cylindrical surface of the flange. The annular projection of the gasket is provided with the transversal external projection that fits into the groove of the retaining ring. The use of the invention reduces dimensions while increasing its reliability.
