ール部材に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to seal members used in joining assemblies exposed to high temperatures, such as exhaust turbocharge flanges.
このように使用条件の厳しい用途においては、
一般のシール材を単体で使用してはシール性を保

目の気密性が貧弱であり、充填材が金属ジヤケツ
トの隙間を介して外気と接触するおそれがある。 In applications with such severe usage conditions,
Since sealing performance cannot be maintained when a general sealing material is used alone, it is known to use a sealing member in which the sealing material is wrapped in a metal jacket, that is, a hollow ring-shaped metal jacket is filled with a filler. be. However, in commonly used sealing members of this type, the airtightness of the joints of the metal jackets is poor, and there is a risk that the filler material may come into contact with the outside air through the gaps in the metal jackets.

充填材の材質によつては、充填材が酸化等により
変質し、シール性が低下することが問題となる。 Therefore, if such a "C-ring" is used in a place exposed to high temperatures, such as the exhaust turbo charge flange mentioned above, the filler material may penetrate through the gap in the metal jacket under high temperature conditions. In such cases, depending on the material of the filler used, the quality of the filler may deteriorate due to oxidation, etc., resulting in a decrease in sealing performance. Become.

難いといつた問題がある。 In this case, if you use a filler with extremely high heat resistance that does not deteriorate due to oxidation even at high temperatures, the selection of the filler will not only have the elastic recovery properties required of the sealing member, but also the heat resistance constraints. Therefore, there are problems in that the fillers that can be selected are limited, and it is difficult to impart a predetermined elastic recovery characteristic to the sealing member.
又、全金属製シール、例えば、金属リング単体
は金属個有の復元特性が不足し、熱によつて生じ

用途には使用し得ない。 Furthermore, all-metal seals, such as a single metal ring, cannot be used in such applications because they lack the inherent restoring properties of metals and cannot follow the deformation of the assembly caused by heat.

レスのリング形状とすることもできる。 This sealing member is used to seal connections that are subject to high temperature stress, such as exhaust turbo charge flanges or joints that require excellent chemical resistance at high temperatures.The inner diameter of the connecting flange is approximately φ.
The height of the seal member is approximately 3.5 mm while the outer diameter is approximately 51.9 mm. The total thickness of the metal jacket is preferably 0.5 mm in such a way that it is not mechanically damaged during or before use and guarantees the desired recovery properties. As fillers it is possible to use elastic or plastic materials, preferably graphite, asbestos, clays, especially kaolin or mixtures thereof. The ring shape of the sealing member is usually an annular ring shape, but it can also be an endless ring shape similar to this.

て使用できる。 The sealing member according to the present invention has the above-mentioned structure, and has double or triple metal jackets covering the filler material, and the joints at both ends of each metal jacket are staggered from each other, so that the filler material is protected from the outside air. Can be shut off reliably. Therefore, even though the filler is exposed to high temperatures due to heat transfer from the sealing surface and the medium to be sealed, the filler does not come into contact with the medium to be sealed or the atmosphere. Even materials such as graphite, which are easily deteriorated by oxidation or the like at high temperatures, can be used as fillers.
