The utility model is further arranged to：The easily curved groove is included to away from the inclined rake in top flat side.
By using above-mentioned technical proposal, deep position thickness is that thickness is most in annular baffle on rake from shallow to deep
It is thin, it is easiest to produce the place of deformation；The positioning to deformation position is realized with this.
The utility model is further arranged to：The easily curved groove further includes connection rake inner side and annular baffle outer wall
Curved portion.
By using above-mentioned technical proposal, curved portion has the deformation surplus of bigger relative to plain film, so that in annular baffle
After becoming along easy curved groove bent, curved portion can discharge deformation surplus, reduce infringement of the deformation to annular baffle.
The utility model is further arranged to：The cross section of the top flat is in the arc away from egative film side protrusion.
By using above-mentioned technical proposal, top flat is convexly curved so that top flat has certain radial elastic deformation
Surplus, occurs overall radial deformation easy to catch.
The utility model is further arranged to：The annular baffle is extended with around the convex of top flat outer ring to one end of top flat
Edge.
By using above-mentioned technical proposal, the intensity of flange lifting top flat outer ring so that the edge of top flat be not likely to produce to
Interior deformation, realizes and stablizing for pipeline is blocked.
The utility model is further arranged to：Great circle is provided with the hollow tube towards the end difference of top flat side.
By using above-mentioned technical proposal, set end difference hollow tube can be easy to carry out radial direction deformation；Further function as
Cushioning effect.
The utility model is further arranged to：The internal diameter of the annular baffle towards egative film side is greater than or equal to the bottom
The outside diameter of piece.
By using above-mentioned technical proposal, therefore egative film can be pressed into annular baffle bottom by pressing egative film, will be close
Seal is compressed, and further improves sealing performance.
The utility model is further arranged to：The side outside of the egative film towards the annular baffle is provided with inclined
Guide surface.
By using above-mentioned technical proposal, guide surface can reduce materials, on the premise of sealing ring enormous amount, significantly
Its economic performance is improved, and is facilitated access on the inside of catch.
In conclusion the utility model has the following advantages：
The 1st, easy curved groove is set so that sealed ring deformation is stablized；It is not easy to produce with pipeline after making sealing ring insertion pipeline deformation
Gap, sealing effect are good；
2nd, egative film can be caught in annular baffle, increase sealing ring integral strength, reduced and taken volume.

Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment, a kind of seal for pipe joints circle, as shown in Figure 1, egative film 3, hollow tube 4, top flat 1 and ring including integrally connected
Shape catch 2.Seal for pipe joints circle generally rubber material, is preferably butadiene-styrene rubber.Its mediella 3 is connected to one end of hollow tube 4；
Top flat 1 is connected to the one end of hollow tube 4 away from egative film 3；Annular baffle 2 is connected on the outer ring of top flat 1, and annular baffle 2 to
Outer incline, the one end of annular baffle 2 away from top flat 1 is towards 4 side of hollow tube.
As shown in Fig. 2, the middle part of the axial direction of annular baffle 2 circumferentially offers easy curved groove 5, easy curved groove 5 is included to away from top
The inclined rake 9 in 1 side of piece and the curved portion 10 of 9 inner side of connection rake and 2 outer wall of annular baffle.Rake 9 progressively subtracts
On 5 correspondence position of little Yi curved grooves, the thickness of annular baffle 2；The most thin position of thickness is then the ground for being easiest to produce bending deformation
Side；And curved portion 10 connects the position of the most pliable deformation of easy curved groove 5, and there is a certain amount of deformation surplus, deformation can be reduced
Infringement to annular baffle 2.Thus annular baffle 2 be inserted into pipeline in after, due to easy curved groove 5 compared to annular baffle 2 remaining
Position preferentially deforms upon, it is achieved thereby that bending the control of deformation position to annular baffle 2 so that and sealing ring deformation is stablized,
Can effectively it be blocked.
As shown in Fig. 2, the cross section of top flat 1 is in the arc away from 3 side of egative film protrusion.So that top flat 1 has necessarily
The surplus of radial elastic deformation, occurs overall radial deformation easy to catch.And one end of annular baffle 2 to top flat 1 be extended with it is convex
Edge 6, flange 6 is around 1 outer ring of top flat, the intensity at 1 edge of lifting top flat.
As shown in Fig. 2, the middle part of hollow tube 4 is provided with end difference 8；The side of great circle is towards top flat wherein in end difference 8
1, the side of roundlet is towards egative film 3；4 inner wall of hollow tube is provided with rounded corner in the turning point of end difference 8.During end difference 8 is easy to
Blank pipe 4 produces axial deformation, so as to can play the role of unhurried current after mounting.
As shown in Fig. 2, and egative film 3 towards being provided with guide surface 7 on the outside of the upper surface in 2 direction of annular baffle.Annular baffle 2
Internal diameter towards arrived tableting one end is greater than or equal to the outside diameter of egative film 3.And the inner wall of annular baffle 2, the inner wall of top flat 1 and hollow
The outer wall three of pipe 4 forms a storage tank 11.
As shown in Figure 2,3, by extruding egative film 3 to 2 side of annular baffle, insert roundlet of the hollow tube 4 on end difference 8
Enter in great circle, the contraction of radial direction occurs；Then egative film 3 extrudes the air in storage tank 11, makes to form negative pressure in storage tank 11,
Egative film 3 is stably secured in storage tank 11.The inclined-plane of period annular baffle 2 and the guide surface 7 of egative film 3 can play guiding and make
With；Snapped onto so that egative film 3 is more enough more convenient in storage tank 11.At the same time after egative film 3 is caught in storage tank 11, sealing ring is whole
Body intensity increases, and takes volume and reduce.
This seal for pipe joints circle, main seal is in the junction of the inner and outer tubes of threaded connection.Installation process, by top flat 1
In side insertion inner tube, egative film 3 is set to be in the outside of inner tube.Top flat 1 be inserted into after, annular baffle 2 under the action of easy curved groove 5
Deformed upon in inner tube, realize and stablizing for inner tube is blocked；So that sealing ring deformation is stablized, can effectively be blocked.And
Egative film 3 is caught in outer tube afterwards, inner tube is threadedly coupled on inner pipe again；Realize the closure to interior conduit connection gap.
The above is only the preferred embodiment of the present invention, is not intended to limit the present invention, all in this practicality
Within new design concept, any modification, equivalent replacement, improvement and so on, should be included in the protection of the utility model
Within the scope of.
