摘要：<p>A fishbone inclined tooth-shaped metal gasket. Annular tooth-shaped grooves are distributed in a circumferential direction of an upper end surface and a lower end surface of the gasket. Teeth of the tooth-shaped grooves are integrally formed with the metal gasket, and are arranged oblique toward a pressure source direction. The section of the tooth-shaped grooves is in the shape of a fishbone, the angle of inclination of the teeth is more than 0 degree and less than 90 degrees, and the contact surface of the top of the teeth and a flange is not a closed angle. The top parts of the teeth are designed into a rounded angle, a flat angle, or a wave arc angle, which avoids damages to the surface of the flange caused by the conventional closed-angle teeth. The design of the inclined tooth improves the rebound resilience of the metal gasket. The tooth-shaped grooves are arranged obliquely to form a plurality of sealed pressure-resistant chambers, so that the pressure from a pressure source can be lowered level by level. The sealed chambers utilize the fluid pressure to generate an effective sealing compensation force, so as to improve the sealing reliability.</p>
