Description
技术领域
本发明属于管道领域，具体涉及多流体同层共挤管道及其生产模头和方法。
背景技术
众所周知，在日常工作生活中，管道是流体的输送工具；目前在单层管道的基础上又有了多层复合管，现有的复合管是由外而内分层共挤复合的，实际与流体直接接触的仅为最内层；为了扩展管道功能，有的在最内层的主体材料中添加单一功能材料，这种单一功能的管材的使用范围受限；还有的在最内层的主体材料中添加二个以上功能材料，但必须保证二个以上功能材料相互之间不发生化学反应；另外，即使二个以上功能材料不发生化学反应，也由于同体积下添加量的减少，而导致功能的弱化，达不到管道设计要求。
发明内容
本发明的目的是：设计多流体同层共挤管道及其生产模头和方法，采用本发明的生产模头和方法生产一种多流体同层共挤管道，使管道最内层在同一层面赋予多种功能。
本发明的技术解决方案是：该多流体同层共挤管道由外而内包括若干层，其特征是：与流体接触的最内层在其3600的截面上按需要划分成若干个圆弧段，圆弧段在同一层面依次排列，每段圆弧的主体材料中根据需要添加功能材料。
更进一步的，管道最内层中添加相同功能材料的圆弧段呈十字对称分布。
更进一步的，每个圆弧段中添加不同色素以作区别。
其中，所述多流体同层共挤管道的生产模头，它包括模具主体，在模具主体上设主流道，通过主流道进料生产管道的最外层；通过分流支架，设计流道将内层所需的物料精准输送到芯棒的特定位置上；再在芯棒上设若干个圆弧段流道，若干个圆弧段流道在芯棒的3600的截面上按需要呈对称分布，每个圆弧段流道进料生产管道的最内层的其中一个圆弧段。
其中，所述多流体同层共挤管道的生产方法是：在管道生产过程中，通过不同的进料流道，将被加热后成为流体的物料分别送入模具主体的主流道和芯棒的若干个圆弧段流道；再利用送料速度、温度对物料流动性的影响，根据需要排定各功能材料在最内层的不同分布面积和分布位置；最后经冷却定型，形成多流体同层共挤管道。
本发明的优点是：
1、管道最内层在同一层面赋予了多种功能，将简单的传送过程变成了一定的反应过程，对所传输的流体分别产生不同作用，选择性地消除或减弱流体的劣性，保留流体的优性，扩大了管材的使用范围。
2、生产管道的模头结构简单，成本相对低廉，使用方便，运行稳定。
3、生产管道的工艺简单，操作容易，工艺指标控制稳定，保障管道质量。
