Octagonal metal ring gasket
installed inside a ladder type ring groove on the surface of the flange, when screw down the connecting bolt, the axial compression and up and down the ladder type slot 1, produce plastic deformation, forming a ring seal belt, establish the initial seal.After booster, under the action of medium pressure, make the ring gasket radial expansion.Gasket with trapezoidal groove cant post more tightly, self-tightening effect.Medium pressure increases, however, also can make the flange and the connecting bolt deformation, caused by a relative separation between the sealing surface, gasket seal than relative decline, thus, ring gasket can be thought of as a half since the tight closure.
