CN202955414U 一种复合软管牙状截面抗压铠装层 失效 - 放弃

一种复合软管牙状截面抗压铠装层
摘要：
本实用新型涉及一种复合软管牙状截面抗压铠装层，其特征在于：它采用异型材缠绕互锁形成，异型材的截面为牙状截面，该截面包括一主梁，主梁沿其长度方向包括第一底壁和第二底壁，第二底壁的两端向同一侧分别一体设置有一端部齿状结构，两个端部齿状结构之间的第二底壁上间隔设置有两中部齿状结构；中部齿状结构到与其相邻的端部齿状结构之间形成端部凹陷区域；两中部齿状结构之间形成中部凹陷区域；两端部齿状结构均向同一侧弯曲；异型材的端部凹陷区域内插入一个相邻异型材的中部齿状结构；异型材的中部凹陷区域内插入两个相邻异型材的端部齿状结构；相邻异型材互相咬合。本实用新型能够增强抗压铠装层的弯曲柔性，同时能够有效防止抗压铠装层相邻截面的相互滑出，因此，可广泛用于种海洋复合软管的结构设置上。
摘要（英）：

The utility model relates to a toothed-section pressure-resistant armored layer of a composite hose. The toothed-section pressure-resistant armored layer is characterized by being formed by winding and interlocking special-shaped profiles with toothed sections. Each section comprises a girder which comprises a first bottom wall and a second bottom wall along the length direction. Two ends of the second bottom wall are respectively integrally provided with an end toothed structure facing the same side. Two middle toothed structures are arranged on the second bottom wall between the two end toothed structures at intervals. End recessed areas are formed between the middle toothed structures and the adjacent end toothed structures. A middle recessed area is formed between the two middle toothed structures. The two end toothed structures are bent towards the same side. The middle toothed structures of the adjacent special-shaped profile are inserted into the end recessed areas of the special-shaped profiles, and the end toothed structures of the two adjacent special-shaped profiles are inserted into the middle recessed areas of the special-shaped profiles. The adjacent special-shaped profiles are meshed to each other. Bending flexibility of the pressure-resistant armored layer can be improved, slipping off of the adjacent sections of the pressure-resistant armored layer can be avoided, and accordingly, the toothed-section pressure-resistant armored layer can be widely applied to the composite hose.
