【正文】 urface, the seal must accordingly be pliable or subject to plastic deformation in order 南華大學(xué)機械工程學(xué)院 to conform to the irregular contact sealing surfaces in such a fashion to affect an appropriate seal. However, gaskets that are typically pliable are not suitable for high temperature operations inasmuch as they are typically limited to temperatures of approximately 450176。 PRIOR ART 現(xiàn)有技術(shù) 高壓墊圈或密封件 ，在不同操作壓力下的密封件和壓力容器這種密封關(guān)系上 遇到許多 困難。 a second outer annular surface formed adjoining said first outer annular surface and adapted to be disposed adjacent the interior surface of the pressure vessel joint。 said annular seal ring having: 環(huán)形密封環(huán)有： a first outer annular surface adapted to be disposed adjacent the interior wall of the pressure vessel joint。包括：環(huán)形密封環(huán) coating means with said annular seal ring for engaging the pressure vessel for effecting a sealable relation therebetween when the pressure vessel joint strains under the high pressures or temperatures encountered within the pressure vessel。 一個壓力容器密封件 ，密封壓力容器接頭，其中這壓力容器有較高內(nèi)壓或溫度，在接頭這點上造成壓力。 Keywords: pressure vessel seal， annular seal ring壓力容器，環(huán)形密封環(huán) A pressure vessel seal for sealing a pressure vessel joint of a pressure vessel having high internal pressures or temperatures therein causing strain in the pressure vessel joint,。南華大學(xué)機械工程學(xué)院 文獻(xiàn)翻譯 Pressure vessel seal Abstract: A pressure vessel seal for sealing a pressure vessel joint of a pressure vessel to prevent fluid migration between an interior wall and an interior surface of the pressure vessel joint including an annular seal ring。 一個壓 力容器密封件 是 用來 密封 兩個單獨的壓力容器的接縫 ，以防止 壓力容器接縫包括一個環(huán)形密封環(huán)之間的內(nèi)壁和內(nèi)表面的流體流動。 The pressure vessel seal for preventing fluid migration between an interior wall and an interior surface of the pressure vessel joint。壓力容器密封是為了防止壓力容器接頭內(nèi)壁和內(nèi)表面的流體流動 Comprising: an annular seal ring。 南華大學(xué)機械工程學(xué)院 涂料是指環(huán)形密封環(huán) 從事壓力容器密封的工具，當(dāng)壓力容器密封接頭處于較高壓力和溫度，它能在其中起到密封關(guān)系。第一個外部環(huán)形表面適應(yīng)于處理壓力容器接頭相鄰的 內(nèi)壁。 第二個外部環(huán)形表面 與第一個外部環(huán)形表面形成毗鄰，適應(yīng)于處理相鄰的壓力容器接頭內(nèi)表面 TECHNICAL FIELD：技術(shù)領(lǐng)域 The field of this invention relates to high pressure seals, particularly for the type used for sealing joints of a high pressure vessel. 這項發(fā)明領(lǐng)域涉及高壓密封， 特別適用于密封高壓容器這種類型的密封接頭。例如， 如果一個高壓墊片或密封件是用在一個粗糙的密封面，密封元件必須相應(yīng)地柔軟或容易彈性 形變，從而為了適合這種不規(guī)律接觸的 常見情況下影響適當(dāng)?shù)拿芊庠?密封面 。 Fahrenheit. On the other hand, for temperature conditions that exceed the capacity of such pliable gaskets, typically metal gaskets are used. Such metal gaskets however require extremely fine surface faces that are difficult to achieve and even more difficult to maintain and service, irrespective of the significant increase in costs encountered in producing such mirrorlike surfaces. 然而，通常柔軟的墊片不適合高溫操作情況，因為它們通常限制在約為 450176。 另一方面， 由于溫度條件超過了這種柔韌墊片和常見金屬墊片承載能力。 As a promise, metal gaskets sealing on metal surfaces can be manufactured to tolerate less than polished sealing surfaces when coated with a relatively soft coating material such as nickel, copper, gold, siver and the like. Such coatings are sufficiently plastic and pliable to fill in the irregularities of the sealing surface where a seal must necessarily be acplished. In these circumstances, the coating must be thin and the amount of imperfection at irregularities permitted on the sealing surfaces must be small. Since such coatings are expensive, only small amounts of s
