A second undercut portion 18h is formed from the second outer annular 南華大學機械工程學院 surface 18b between the second cavity 18e and outer extremity 18f of the second outer annular surface 18b. A first inner annular surface 18i is preferably formed adjacent outer extremity 18d with second inner annular surface 18j formed between the first inner annular surface 18i and outer extremity 18f. As a consequence, the annular seal ring R of the present invention is of a substantially quadrilateral configuration having two truncated end portions at the outer extremities 18d, 18f, with such quadrilateral configuration being substantially of that of a parallelogram. 形成在第二環(huán)形外表面 18b的側向部分 18h是在第二凹腔 18e和第二環(huán)形外表面18h的 外 端 18f之間。那固定銷 14,16也有輕微的錐度結構，這結構 能增強圖紙中容器 10,12部分的緊固。 本發(fā)明的壓力容器密封 S是適合被用于一個壓力容器 P內(nèi)。 FIG. 5 is a partial, sectional view of the extremity of the pressure vessel seal of the present invention, with a low pressure environment within the pressure vessel。 The pressure vessel seal of the present invention is for sealing a pressure vessel joint of a pressure vessel and includes an annular ring, a coating with the annular ring for engaging the pressure vessel for effectuating a sealable relation there between under varying pressure conditions, with the annular seal ring having first and second outer annular surfaces disposed adjacent to the pressure vessel, with coating reservoirs formed with the outer annular surfaces adjacent to the extremeties thereof for receiving the coatings therein for permitting the coatings to sealably engage the pressure vessel joint while storing the coating for enhanced spring back of the coating under varying pressure conditions. 本發(fā)明 的 壓力容器密封 元件 被用于 密封 兩個獨立 壓力容器 聯(lián) 合的 接頭 ，它 包括一個 圓環(huán)，圓環(huán)涂層 用于 在不同的壓力條件下 在壓力容器 中維持 密封的關系， 而 環(huán)形密封環(huán)有第一和第二外環(huán)形表面 來 處理相鄰的壓力容器 ， 形成 涂層的 外 層 和 外部環(huán)形表面相鄰的 結構，用于 接受其涂層 ，而在其中 允許 涂層密封 嚙合 壓力容器 接頭， 同時存儲涂層 并 增強 涂層在不同壓力條件 的 回彈 。在這種情況下， 涂料必須薄，而且在密封面不允許的缺陷的數(shù)量必須少 。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?shù)拿芊庠?密封面 。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。 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,。 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。這種金屬墊片卻需要非常好的表面接觸面， 這是難以實現(xiàn)的，甚至更加難以維護和服務，更 不論在生產(chǎn)這種 鏡面表面會顯著增加成本。 編號 3895735， 4009798，和 4054224。 圖 3是與本發(fā)明相似于圖 2所示的壓力容器密封的擴大截面視圖，但被表現(xiàn)出完全偏轉，由于高壓作用在壓力容器內(nèi)。 南華大學機械工程學院 DESCRIPTION OF THE PREFERRED EMBODIMENT 更具體 完善的說明 In the drawings, the letter S designates generally the pressure vessel seal S of the present invention. The pressure vessel seal S is for sealing a pressure vessel joint J of a pressure vessel P to prevent fluid migration therebetween the pressure vessel seal S and the pressure vessel P. The pressure vessel seal S includes generally an annular seal ring R, coating means C with the annular seal ring R, and coating reservoir means M formed with the annular seal ring R. 在圖紙中，字母 S一般地指本發(fā)明壓力容器密封 S。
