但是如果涉及到的是大型的压縮空气管路系统, 这样就需要大直径的 输送管路和小直径的输送管路配合使用, 上述专利的管接头适用用于小管 路的连接, 在应用与大直径管路的时候, 由于大管路的自重, 上述专利的 管接头在连接强度上就无法满足要求。 发明内容
为了解决现有管接头无法满足在大直径的管路中使用的技术缺陷, 本 发明的目的是提供一种大直径压缩空气输送管道的连接装置, 该装置适用 于大直径管路连接, 具有结构简单, 实施方便, 连接牢固的特点。
为了实现上述的目的, 本发明采用的是以下的技术方案。
大直径压缩空气输送管道的连接装置, 该装置由金属外壳体和密封装 置构成, 金属外壳体由第一半环体和第二半环体构成, 第一半环体和第二 半环体之间设有锁紧构件相连接: 金属外壳体的内腔设有环形安装槽, 环 形安装槽的两侧分别设有第一环形斜面, 第一环形斜面向两端呈收拢状, 环形安装槽通过第一环形斜面与金属外壳体的内腔过度; 所述的密封装置 由环形架体、 两个压环和两个 "0"形密封圈构成, 两个压环分别活动套设 在环形架体的两侧; 压环的正截面呈 " U" .型, 压环的中部设有安装孔, 肩 部分别设有第二环形斜面, 两个 "0"形密封圈分别设置在两个压环内圈的 拐角部, 环形架体的两个端部分别与两个 " 0"形密封圈相抵; 并且, 在压 环内圈的拐角部设有环形弧面或环形斜面过度, 或者在环形架体的两个端 部内侧分别设有第三环形斜面; 所述的第一半环体和第二半环体锁紧之后, 密封装置容置在环形安装槽和第一环形斜面内, 第二环形斜面与第一环形 斜面相抵, "0"形密封圈的内径小于安装孔的内径。
作为优选, 第一环形斜面的外侧金属外壳体的内腔周向连续或间隔设 有两条定位卡台, 两条定位卡台之间形成用于卡接输送管道上的凸环的限 位凹槽。 限位凹槽可以用于对于设有凸环的输送管道进行轴向的定位。
作为优选, 所述的压环内圈的拐角部设有环形弧面或环形斜面过度, 所述的环形架体的两个端部内侧分别设有第三环形斜面。
作为改进的技术方案, 上述的第一半环体和第二半环体的对接部分别 设有锁紧平板, 所述的锁紧构件为螺栓, 螺栓设置在锁紧平板上将第一半 环体和第二半环体锁紧。
作为改进的技术方案, 上述的第一半环体的锁紧平板上设有安装口, 第二锁紧半环体的锁紧平板上设有螺纹口, 所述的螺栓穿在安装口上与螺 纹口相连接。
作为改进的技术方案, 上述的第一半环体和第二半环体的一侧对接部 的锁紧平板上还设有弹性连接件连接第一半环体和第二半环体。 弹性连接 件一方面用于连接第一半环体和第二半环体, 另一方面也可以初步定位第 一半环体和第二半环体, 便于安装。
