Further, the inner diameter of the sealing plate is larger than the inner diameter of the baffle. The inner diameter of the sealing plate is slightly larger than the diameter of the pipe and smaller than the diameter of the insulation layer. The interface should be polished before use to facilitate embedding into the insulation layer of the pipe.

Preferably, at least two groups of the sealing plates are provided.

The beneficial effects obtained by adopting the above-mentioned structure of the utility model are as follows: the pipeline emergency repair device capable of working under pressure is simple in structure, reasonable in design, low in cost, and easy to operate, which can effectively improve the pipeline emergency repair efficiency of the staff and avoid users or heat exchange The station stops heating, which reduces the construction cost. The device is also suitable for emergency repair construction of liquid pipelines such as running water.
