摘要： A sealing device (11) for use in a sealing gland (14) in a first body to form a seal between the first body (15) and a second body (16). The sealing gland (14) has a bottom surface (58) and first (60A) and second (60B) side surfaces extending from the bottom surface (58). The sealing device (11) includes a seal body (13) having, when the seal body (13) is uncompressed and viewed in cross-section, a generally uppermost portion and a generally lowermost portion. The seal body (13) includes a first material (10) which is at least partially deformable. The first material (10) is generally disposed at least partially along the generally uppermost portion and at least partially along the generally lowermost portion thereof. The first material (10) contacts the bottom surface (58) of the sealing gland (14) when the seal body (13) is inserted into and at least partially disposed within the sealing gland (14). A second material is harder than the first material. The second material (12) is disposed generally along at least a portion of a lateral side of the seal body, when the seal body is viewed in cross-section, to form a shield. Wherein when the seal body (13) is positioned within the sealing gland (14) and is compressed the seal is formed between the first body (15) and the second body (16) by the first material (10) and an additional seal is formed by the shield (25) for extending the operational life of the sealing device (11) while preventing fluid flow between the first body (15) and the second body (16).
摘要翻译：一种密封装置（11），用于在第一主体中的密封压盖（14）中，以在第一主体（15）和第二主体（16）之间形成密封。密封压盖（14）具有从底表面（58）延伸的底表面（58）和第一（60A）和第二（60B）侧表面。密封装置（11）包括密封体（13），当密封体（13）未被压缩并且在横截面中观察时，密封体（13）具有大致最上部分和大体上最低的部分。密封体（13）包括至少部分可变形的第一材料（10）。第一材料（10）通常至少部分地沿着大致最上部分并且至少部分地沿其大致最低部分布置。当密封体（13）插入并至少部分地设置在密封压盖（14）内时，第一材料（10）接触密封压盖（14）的底表面（58）。第二种材料比第一种材料更硬。第二材料（12）通常沿密封体的侧面的至少一部分设置，当密封体在横截面上观察时，形成屏蔽。其中当密封体（13）位于密封压盖（14）内并且被压缩时，密封件通过第一材料（10）形成在第一主体（15）和第二主体（16）之间，并且附加的密封件由所述屏蔽件（25）形成，用于延长所述密封装置（11）的使用寿命，同时防止所述第一主体（15）和所述第二主体（16）之间的流体流动。
