Description

一种新型复合管道
技术领域
本实用新型属于环保设备技术领域，具体涉及了一种新型复合管道。 
背景技术
在冶金、煤炭、电力和环保等行业需用大量的耐磨防腐管道。现有技术中，这类管道有衬高分子复合材料(如塑料、橡胶、聚氨酯等)管、内衬搪瓷贴片复合管和离心浇注复合搪瓷管等。衬高分子复合材料管虽耐酸耐碱耐水解，具有良好的防腐性能和高弹性，但存在耐磨损性能差等不足；内衬搪瓷贴片复合管，虽硬度高、耐磨损性能好，但存在防腐性能差等不足；离心浇注复合搪瓷管，存在内衬搪瓷层微观裂纹多，质脆易碎，容易局部脱落失效，且不耐腐蚀，搪瓷层容易脱落等不足。 
实用新型内容
本实用新型的目的是针对上述不足而提供的一种新型复合管道，且制造工艺简单，能满足各种不同需求。 
本实用新型的技术方案在于： 
一种新型复合管道，其特征在于：包括管体，所述管体内壁设置有耐腐蚀层，所述耐腐蚀层内壁设有耐磨层，所述耐腐蚀层采用高分子复合材料，所述耐磨层由多个搪瓷组成。 
进一步的，所述搪瓷的外壁弧度与耐腐蚀层内壁弧度一致。 
进一步的，所述搪瓷的数量大于等于2。 
进一步的，所述耐腐蚀层为高分子复合材料。 
进一步的，所述管体包括直管、弯管、三通管或异型管。 
进一步的，所述管体为金属管体或高分子复合材料的管体。 
本实用新型管体内衬高分子复合材料层作耐腐蚀层，耐磨面为粘贴搪瓷，利用拱型原理和上述搪瓷的特殊结构形成的搪瓷层。搪瓷的宽度、边角锥度和接角锥度等参数经CAD设计完成，不同口径的管径采用相匹配的不同规格的搪瓷，保证了底管内壁所贴搪瓷排列紧密、间隙小和内表面平整；在装配过程中，搪瓷与搪瓷之间、搪瓷和高分子复合材料的耐腐蚀层之间涂有粘接剂(根据输送介质的种类选用不同粘接剂)可确保搪瓷互锁而形成的内层与底管结合紧密，搪瓷不脱落。 
本实用新型把管体管道优良的力学性能、高分子复合材料良好的耐腐蚀性能和搪瓷材料优异的耐磨性能有机地结合起来，复合形成一种性价比优良的复合管。其具有良好的抗冲击性能，耐磨防腐性能优异，减震效果好，物料输送噪音低。 
下面结合附图提供的实施例对本实用新型进一步详述。 
附图说明
图1为本实用新型的复合弯管结构示意图。 
图2为本实用新型的复合三通结构示意图。 
图3为本实用新型的复合直管结构示意图。 
图4为本实用新型的结构示意图。 
图5为本实用新型的搪瓷局部示意图。 
具体实施方式
图1、图2、图3中，金属管体2，在金属管体内设有高分子复合材料的耐腐蚀层3；高分子复合材料的耐腐蚀层3内有若干个搪瓷互锁而形成的耐磨面4。1为法兰。 
图4中，金属管体2内衬耐腐蚀层3，耐腐蚀层3内壁设有耐磨面4，耐磨面4径向由10个搪瓷5组成。10个搪瓷5在管道径向相互嵌合形成360°机械互锁结构。搪瓷5的外壁弧度与耐腐蚀层3内壁弧度一致。搪瓷与搪瓷 之间、搪瓷和高分子复合材料的耐腐蚀层3之间涂有粘接剂。搪瓷5两端面即径向连接面为可与相邻搪瓷相互对应的凸凹结构，搪瓷5两侧面即轴向连接面为相互对应的斜边结构。 
图5中，搪瓷5-1与搪瓷5-2径向连接面为相互对应的凸凹结构，利用拱型原理，相邻搪瓷相互嵌合形成360°机械互锁结构。
