    摘要: The present invention introduces a metal seal flange assembly for a vacuum system. A new designed metal gasket has a crosses-section shape of irregular quadrangle with two sharp angle forms by the longer base and legs. The long base of the irregular quadrangle is the vertical inner wall of the metal gasket. A preferred cross section shape of the metal gasket is trapezoid or isosceles trapezoid. this design can reduce the normal force applied to the metal seal flange assembly and reduce the number of bolts used in a limit working space.
