Description of the invention (1) '--[Technical field to which the invention belongs] The present invention provides an improved ring-type gasket, especially an improved design made for an O-ring to provide grooves on the gasket surface. A ring-shaped washer with sufficient elastic compression space inside. [Prior art] Referring to the first figure, a combination diagram of a conventional ring-shaped cymbal ring 1 (o-ring) assembled on the valve 2 is shown. The ring-shaped gasket 1 is made of an elastic material such as rubber. A ring body (as shown in the second figure), the ring body has a flat bottom surface 11, two side walls 12 extending vertically upward from the bottom surface, and a spherically protruding top surface 13, and the valve 2 is to be sealed The gasket surface 20 has a groove 21 for receiving the ring-shaped gasket 1. The cross-sectional shape of the above groove 21 is almost rectangular, and the width between the two side walls 12 of the washer 1 is set to be approximately equal to the width of the groove 21, so that the washer j and b are fitted into the bottom of the valve 2 with a matching base. The annular groove 21 is inside, and the washer 1 is provided with a top section pressing portion 15 protruding from the groove 21. As a result, when the valve seat 3 and the valve 2 are pressed together, as shown in the third figure, the pressure acting on the valve gasket surface 20 will press the washer 1 out of the pressing portion 15 of the groove 21 and pass through the washer. The compressible elastic action of 1 compresses the washer 1 into the groove 21 to make the gasket surface 20 have a tight pressing effect. Although the conventional ring washer 1 has some effects in terms of compactness and effectiveness, if the clearance between the ring washer 1 and the groove 21 is too small, the washer 1 will not have enough space for elastic movement, resulting in a small allowable contact pressure. Insufficient compression force is not sufficient, and it is not conducive to the assembly of the gasket 1. If the gap is too wide, the gasket 1 and the groove 21 cannot make full tight contact pressure.

Description of the invention (2), and washer 1 cannot be used for execution. Step-by-step, when the structure of the installed solid washer i does not have a space for elastic movement, the square groove 21 is installed when there is a large number of washer-fitting parts 15 and ^ the valve seat 3 and the valve 2 are pressed. Together 'will), when used for contact pressure comparison :: vertical? : Outside 21 (as shown in the third figure, the surface of the gasket 1 is easy to be plastically deformed and squeezed; in the recess? The peripheral edge portion 14 around the opening of the outer groove 21 is located outside the recess, and the size of ㈣i is larger than the square recess. The groove 2 enters ^. It is inserted into the groove 21 and installed in the groove 21; and when the cross-sectional area of the ring 1 is small = the concave m, the ring 1 and the inner wall of the groove 21 cannot make close contact, and there will be a vacuum pumping. The immovable situation occurs. In addition, when the size of the gasket ^ is smaller than the square groove 2, when the gasket m is installed vertically downwards (ie, there is no support under the gasket), it will cause the gasket to have a capacity. The conventional ring washer does have problems such as the inability to enlarge the dimensional tolerance and the allowable contact pressure, and this problem greatly affects the use of the ring washer, making it difficult to provide a minimum. A large amount of gasket surface is exposed to the gasket surface to have a completely tight sealing effect, 'especially' for valves used in the equipment of ultra-vacuum equipment in semiconductor factories'. Gaskets under high corrosive gas and plasma environments are Required More precise dimensional tolerances. If the structure is not designed properly, it will affect the seal and cause great losses. Therefore, there should be another improved ring washer to produce the ring washer in the groove on the gasket surface.
