Technical Problem
[0002]在燃气管道系统中，由于工艺需求或维护需要，经常需要在管道上进行开孔作业，并在特定情况下对管道进行临时性封堵，传统的管道封堵方法多采用机械堵塞、焊接封板或使用外部夹具等方式，这些方法存在操作复杂、封堵不严密、拆装困难、适应性差等问题，特别是在带压作业或易燃易爆介质环境中，传统封堵方式不仅效率低下，还存在较高的安全风险，例如，机械堵塞依赖人工操作，难以实现精准定位与均匀密封，而焊接封堵则需停输、清管，影响生产连续性，且存在火灾和爆炸隐患，因此，我们希望设计一种管道开孔封堵机构，从而解决这个问题
Benefits of technology
1、通过设置封堵机构，利用螺杆中空设计并集成注气口，可直接向封堵气囊充气，支撑臂与滑槽的滑动配合，结合四个周向均匀分布的支撑臂，有效增强了封堵过程中的导向性与稳定性，防止气囊偏斜，螺纹旋合结构便于精确控制封堵气囊的升降，实现封堵与解除，提升了操作的便捷性与工作效率。
