Title: (EN) METAL GASKET
(ZH) 金属密封垫
Abstract: front page image
(EN) The purpose of the present invention is to provide a metal gasket that can demonstrate an excellent sealing effect against foreign matter such as salt water, and moreover is provided with a structurehaving a low reactive force compatible with the situation in which the required sealing pressure is low when the metal gasket is in a fitted, in-use state. Provided to achieve said purpose is a metalgasket clamped between a pair of housings, said metal gasket sealing the inner space of the housings and inhibiting the penetration of foreign matter into gaps between the housings and the gasket, wherein the metal gasket has a straight section, the entire face of which is planar from the inner peripheral edge up to the outer peripheral edge, and a bending bead section that comes into contact withone of the housings is integrally provided to the outer peripheral edge of the straight section so as to be oriented diagonally outward, said bending bead section concurrently using an inward seal that seals the inner space of the housings and an outward seal that inhibits the penetration of foreign matter into gaps between the housings and the gasket.
(ZH) 本发明提供一种金属密封垫,能够对盐水等外部异物发挥优异的密封效果,并且在此基础上,还可对应安装使用金属密封垫的状况为要求密封压力较低的情况而具备较低反作用力的构造。为了实现该目的,该金属密封垫夹在一对框体之间,密封框体的内部空间,并且抑制外部异物侵入框体与密封垫之间的间隙,具有从内周缘部到外周缘部使整面呈平面状的直线部,在直线部的外周缘部一体设置有朝向斜外侧设置且与一个框体接触的弯曲凸缘部。弯曲凸缘部同时用作密封框体的内部空间的对内密封件以及抑制外部异物侵入框体与密封垫之间的间隙的对外密封件。
