综上所述，本发明密封保温管的制造系统及制造方法通过在传送杆133一端处设置感应开关，利用感应开关控制密封挤出机300的开关状态来对密封材料进行定量供给，使得密封层间隔熔接在管道体的内侧壁，很好地节约制造成本；另外，通过控制密封挤出机300挤出的密封材料的温度，使得密封材料在较高温度下与管道体内侧壁进行熔接，不需要再次对密封材料进行加热即可和管道体内侧壁进行熔接，减少了操作工序，节省能源，有效提高了生产效率；进行熔接后的密封层与管道体端部形成无缝连接，因此不会发生渗漏现象，成为一体的空调密封保温管在装配时也非常方便，不会因密封层与管道体之间的连接缝隙造成漏气问题，无需再通过人工检测气密性，避免了产品在使用过程中造成的故障问题，有效提升了产品使用质量。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明的保护范围应以所附权利要求为准。
