Technical Problem

[0003]现有维修管道的设备，使用时需要通过连接管将弹性气囊送入管道中，再通过连接管对其进行充气使弹性气囊膨胀从而对管道进行封堵，但是连接管较软，无法对弹性气囊进行有效的支撑，在弹性气囊未完全膨胀时，在管道内部受到水流冲击时容易向管道的外部发生移动，容易导致维修工作停滞，因此，本实用新型提供一种供水管道维修用堵水设备，以解决上述问题

Benefits of technology

1、本实用新型通过防滑纹路能够将气源与进气管之间进行连通，弹性卡环能够与进气管后端的外表面进行弹性抱紧，并且通过限位环的设置能够对弹性卡环的位置进行限制，在支撑杆插设于连通槽的内部时，通过限位板能够对弹性气囊进行阻挡，并且在对弹性气囊的内部充气时，推动推板能够推动弹性气囊向管道的内部进行移动，并且通过支撑结构整体能够对弹性气囊起到稳定的支撑作用，该设计能够有效的避免弹性气囊从管道的内部脱出。
