内容記述 | To clarify leakage characteristics of the flat metallic gasket, the leakage rate of a gas and real contact area of the seal surfaces were measured under several closing loads. The static seal used in this study consisted of the ring-shaped copper gasket and the two steel flanges which held the gasket. The contact surfaces of the flanges were finished by the lathe. So far the following two directions on the gasket surface were pointed out as the leakage flow paths. One was the radial direction perpendicular to the lathe turning groove and the other was circumferential direction along the groove. As the closing loads increased, the leakage flow in the radial direction ceased and only the leakage flow in the circumferential direction remained. To determine the closing load, that is the contact pressure, at which the radial leakage flow ceases, the real contact situation on the gasket surface should be observed. In this paper the real contact area between the copper gasket and the steel flange was measured using the thin polymer film of 1 μm in thickness. As a result the contact pressure over which the radial leakage ceased could be predicted from the observation of the thin polymer film. In addition, the cross section of the aperture for the leakage flow in the circumferential direction was evaluated from measured real contact area, and the leakage rate was estimated by the assumption of laminar flow. It agreed well with the measured leakage rate. | |||||
