description The utility model relates to a sealing-ring for a high-pressure cooker, whose internal side surface is provided with an opening outside type groove. The two internal side hems 1 of the groove and the bottom hem 2 of the groove are of convex arc shapes. The side hems 1 is connected with the bottom hem 2 by a circular arc 3. The radius of R1 is 5-15 millimetres, the radius of R2 is 1-2.5 millimetres, and the radius of R3 is 0.5-1.5 millimetres. Because a stiffening rib is arranged between the side walls of the side wall, a sealing face is subjected to a certain tension all the time and the service life of the sealing-ring is prolonged beneficially. Because the two internal side hems of the groove are designed into arc shapes, a cooker lid is switched on and off easily. The sealing-ring can be made by adopting silicon rubber materials so as to further enhance the service life the sealing-ring and the sealing performance of the sealing-ring.
