Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in Figures 2 and 3, a kind of sealing gaskets of Hafu joint that can be engaged, including be embedded in the He of the first housing of pipeline leakage plugging device 1 respectively
The first sealing gasket 3 and the second sealing gasket 4 of the opposing end surface of second housing 2, the horizontal bar of the side of the first sealing gasket 3 are provided with
First fin 5, the horizontal bar of the other side of the first sealing gasket 3 is provided with the first groove 6；The second sealing gasket side 4
Horizontal bar be provided with the second groove 7 for matching with first fin 5, the level of the other side of the second sealing gasket 4
Bar is provided with the second fin 8 matched with first groove 6.It is preferred that：First fin 5 and first groove 6
For arc-shaped or triangle.
When to 1 leak stopping of pipeline, the first sealing gasket 3 and second sealing gasket 4 pass through the first housing 1 and the second housing 2
Be mounted opposite, the first fin 5, the second groove 7 on the first sealing gasket 3 respectively with the second groove 7 on the second sealing gasket 4,
The occlusion of two fins 8 is got up, and on the one hand increases the area in sealing contact of sealing gasket, improves sealing effectiveness；Other projection and groove are handed over
Error articulation can effectively prevent the relative slip of sealing gasket together, prevent the generation of leakage.
Four corners of first sealing gasket 3 and second sealing gasket 4 are equipped with projection 9, and the bottom surface of projection 9 is
The inclined-plane or arc surface matched.When first sealing gasket 3 and second sealing gasket 4 are mounted opposite, corresponding projection 9 it is oblique
Face or arc surface can extrude mutually, further improve sealing effectiveness.
As shown in figure 4, being the unequal pipeline leakage plugging device of radial dimension for socket joint pipeline leakage plugging device, Fig. 5-7 is relative with socket joint Hough
The three-view diagram for the sealing gasket answered.Sealing gasket described in the utility model can also be used for socket joint pipeline leakage plugging device after corresponding adjustment.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
