Preferably, there are multiple embedded snap points, and the embedded snap points are evenly arranged along both sides of the symmetry line of the sealing strip and the semi-arc sealing ring.

Preferably, the embedded snap point is a flat convex body with the same die angle as the sealing strip and the half-arc-shaped sealing ring. The outer surfaces of the arc seal ring are parallel.

Preferably, the length direction of the embedded card point is parallel to the insertion direction of the plug-in segment.

Preferably, the length dimension of the embedded card point is less than 1.5mm of the plug-in stroke of the plug-in segment.

Preferably, the sealing strip is made of rubber material.

Compared with the prior art, the beneficial effects of the present utility model are:

The utility model belongs to the technical field of pipeline emergency repair equipment, and specifically discloses a pipeline pressurized emergency repair joint gasket. The thickness of the connecting section is slightly less than but not equal to the reserved groove width of the emergency repair joint shell during manufacture. The embedded card points are added to the thickness of the plug-in section. On the one hand, the elastic support and snap connection of the gasket itself is realized through the elastic deformation of the embedded card points, so as to ensure the effective fastening of the entire gasket to the repair section shell; On the other hand, the elastic force of the embedded snap point will not hinder the quick connection and assembly of the reserved groove between the sealing gasket and the outer casing, so as to ensure the working efficiency. Since it can not only ensure its good sealing performance, but also eliminate its traditional bonding process and reduce production costs, it can effectively ensure that enterprises can obtain economic benefits. The utility model has the advantages of simple structure, convenient operation and strong practicability.
