[0026] 参照图 1、 图 2、 图 3、 图 4、 图 12， 一种流体分流装置,包括容器 10和多个支线管 路连接装置； 容器 10包括圆通状的中段 11、 收拢状的前段 12、 收拢状的后段 13 ， 前段 12和后段 13通过焊缝 16和焊缝 17连接为一体， 并形成具有空腔 19的容器 ； 前段 12上有流体主通道 14、 后段 13上有泄放接口 15， 中段 11的圆柱壁上有 6个 冲压塑变或拉伸塑变形成的平面， 每个平面上幵设有用于与支线管路连接装置 装配的圆孔 18; 每个支线管路连接装置包括接头 20、 扣合件 30和薄片状环形密 封件 40。 接头 20大致呈圆管状， 具有贯通的中心孔， 第一端 21具有用于连接外 部设备或管道的阴螺纹 22， 阴螺纹处形成中心孔， 该中心孔沿着接头轴向贯通 至接头第二端 29， 中心孔在第二端 29的直径小于阴螺纹处的直径， 即位置 25处 的直径小于位置 28处的直径， 使得中心孔在靠近第二端 29形成环状平台 24， 并 且在环状平台 24上设置有纹路或凸起， 接头第二端的端面 23是平面， 端面 23上 设置有凸起于端面 23的环形台 26。 扣合件 30包括阴螺纹部 33、 薄壁部 32、 外沿 部 31、 突起部 322和中心孔， 薄壁部 32的外部直径与阴螺纹部 33外部直径相同， 薄壁部 32塑变前中心孔直径大于阴螺纹部直径， 薄壁部 32的壁厚小于阴螺纹部 3 3壁厚， 薄壁部 32的内壁 322上、 靠近阴螺纹部 33的一侧设置有引导凹槽 323， 该 引导凹槽 323是连续的、 环形凹槽， 且引导凹槽包围薄壁部的中心孔， 引导凹槽 323的断面呈弧形； 薄壁部 32外壁设置有拉丝纹 321以提高扣合件与容器内壁的 摩擦力， 外沿部 31的下缘 311设置有纹路以提高扣合件与接头的摩擦力， 阴螺纹 部的前端 333呈收拢状， 扣合件 30的中心孔贯通阴螺纹部 33、 薄壁部 32和外沿部 31； 扣合件 30的阴螺纹部 33和薄壁部 32依次穿过接头 20、 密封件 40和容器圆孔 1 8， 在轴向、 相向方向上的外力作用下， 薄壁部 32塑变塌陷、 并向薄壁部径向向 外鼓起， 形成突起部 322， 使扣合件外沿部 31的下缘 311抵顶在接头的环状平台 2 4上、 突起部 322抵顶在环绕圆孔 18的容器内壁上， 实现接头 20与容器平面 112形 成轴向夹紧， 扣合件 30塑变吋挤压容器内壁， 但容器中段 11的平面 112不会发生 塑变， 使容器平面 112贴合在接头第二端面 23上， 并将密封件 40夹紧在端面 23与 薄壁部 32外壁之间， 环形台 26能有效加强密封效果。
图 6-图 12展示了一个流体分流装置的支线管路安装方式， 图 5是夹紧设备的示 意图， 支线管路具体安装方法为： 将夹紧设备 50的芯轴 52的阳螺纹端 521与扣合 件阴螺纹部的阴螺纹 332旋合， 旋合朝向如图 6所示， 再将扣合件的收拢状前端 3 33依次穿过接头 20、 密封件 40、 圆孔 18， 并使套筒端部 511抵顶在扣合件的上缘 312， 然后再套筒 51上施加力 Fl、 在芯轴 52上施加力 F2， 以使扣合件轴向压缩， 薄壁部 32首先在引导凹槽 323处幵始径向向外形成鼓起 324， 随着轴向压缩力的 增大， 鼓起 324牵引薄壁部其余部分继续向外鼓起， 形成突起部 322， 随着力进 一步加大， 突起部 322抵顶在容器 10内壁， 并挤压容器内壁， 使中段 11的平面 11 2贴合在接头 20的端面 23上， 最后将芯轴 52与阴螺纹部 33旋幵， 如图 12所示完成 一个支线管路的安装。 按照以上相同的方法， 安装剩余的支线管路。 与不预先 在容器圆柱壁加工平面相比， 在容器的圆柱壁上预先加工平整的平面， 能得到 更为理想的密封效果， 而且还能确保多个接头朝向的一致性。
实验证明， 引导凹槽 323设置在内壁比外壁有效； 断面设置成弧形能确保引导 凹槽 323形变过程中不会断裂、 且向外鼓起的突起部 322形状更规则、 夹紧力一 致。 连续的、 环形结构的引导凹槽 323能确保鼓起的突起部 322塑变一致性和夹 紧力。
