Specific implementation mode
Embodiment 1：As shown in Figures 1 to 4, fire-fighting groove type pipe, including sealing ring, the sealing ring include ontology
1 and sealing lip 2.
It is equipped with protruding portion 3 close to the side of pipeline when ontology 1 uses, protruding portion 3 is located at 1 middle part of ontology, is set on protruding portion 3
There are multiple grooves 4, multiple grooves 4 circumferentially distributed along ontology 1；
It is smaller than 1cm between multiple grooves 4.
The quantity of sealing lip 2 is two, and two sealing lips 2 are located at 1 both sides of ontology, sealing lip 2 far from ontology 1 one
The width at end is more than the width of the other end.
4 one end of groove is arranged close to one of sealing lip 2, and the other end is arranged close to another sealing lip 2.
Multiple grooves 4 are circumferential uniformly distributed along ontology 1.
As shown in Figures 2 and 3, length of the groove 4 close to the side of sealing lip 2 is more than the length at 4 middle part of groove.
As shown in Fig. 2, being more than the width of another side when groove 4 uses close to the width of pipeline one side.
3 cross section of protruding portion is arc, and the height in the middle part of protruding portion is more than the height of both sides.
Arc-shaped transition slot 5 is equipped between protruding portion 3 and sealing lip 2, multiple grooves 4 are connected to arc-shaped transition slot 5 respectively.Arc
Shape lead-over groove 5 is circumferentially disposed along ontology 1.The shape of arc-shaped transition slot 5 is annular.The shape of 5 cross section of arc-shaped transition slot is arc
