Description

波纹包覆垫片
技术领域
本实用新型是一种垫片,特别是一种波纹包覆垫片。
背景技术
现有的垫片,在工作过程中由于受压紧应力的影响,垫片会产生变形,所以密封性差。
发明内容
本实用新型的目的是为了克服现有垫片易变形密封性差的缺陷,发明一种波纹包覆垫片。
本实用新型的目的是按如下的方式来实现的:所述波纹包覆垫片,其特征在于:其由垫片外壳、金属波纹夹套、波纹式填充物和膨胀石墨材料组成,金属波纹夹套的两侧设有波纹式填充层,波纹式填充层的外侧设有膨胀石墨层,膨胀石墨层的外侧设有垫片外壳。
本实用新型的积极效果如下:本实用新型具有特别优良的密封性;具有很好的回弹性并能长期保持优异的密封性能;具有很高的安全可靠性;可以减少金属材料之间的摩擦,缓解垫片变形。
附图说明
图1是本实用新型主视结构图; 
图2是本实用新型俯视结构图;
图3是本实用新型断面放大图。
图中:1、垫片外壳;            2、金属波纹夹套;       
3、波纹式填充物;        4、膨胀石墨材料。
具体实施方式
如图1图2图3所示,所述波纹包覆垫片,其特征在于:其由垫片外壳1、金属波纹夹套2、波纹式填充物3和膨胀石墨材料4组成,金属波纹夹套2的两侧设有波纹式填充层3,波纹式填充层3的外侧设有膨胀石墨层4,膨胀石墨层4的外侧设有垫片外壳1。
本实用新型在金属波纹夹套及膨胀石墨层的双重作用下,具有特别优良的密封性;由于金属波纹夹套具有均匀构造的波纹,使所受的应力分布均匀,不必担心使用时会发生应力松驰或应力集中,因此具有很好的回弹性并能长期保持优异的密封性能;由于金属波纹夹套与膨胀石墨层复合成牢固的整体,不剥离,不会被压“散架”或“压馈”,因此具有很高的安全可靠性;本实用新型在较高的压紧力下可以减少金属材料之间的摩擦,缓解垫片变形。
