Abstract
The utility model discloses a bimodal formula water -swelling rubber circle, including columniform rubber body rubber body's one end is equipped with the retaining ring rubber body is last to be close to one side complex of retaining ring has the water -swelling rubber circle of two rings of parallels, the cross sectional shape of water -swelling rubber circle is triangle -shaped. The utility model discloses can make the pipeline when the soil property changed the later stage, ensure good sealed effect.
Description
Technical field
This utility model relates to pipeline connection area, particularly relates to a kind of water swelling rubber ring.
Background technology
In connection between the tube and tube of large-diameter pipeline, conventional encapsulating method is to use rubber ring.But existing rubber ring cannot ensure the error caused due to the tolerance in tubing manufacture process, thus is easily generated seepage.After piping laying is good, also can produce various unpredictable change, such as the soil is porous, ground settlement etc., so that the seal failure of pipeline.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of double-peak type water swelling rubber ring, it is possible to makes pipeline when the later stage, soil property changed, ensures good sealing effectiveness.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is:
A kind of double-peak type water swelling rubber ring is provided, including cylindrical rubber body, it is provided with back-up ring in one end of described rubber body, in described rubber body, the side near described back-up ring is compounded with the water swelling rubber ring that two circles are parallel, and the cross sectional shape of described water swelling rubber ring is triangle.
In one preferred embodiment of this utility model, described water swelling rubber ring cross sectional shape is triangle, and described triangle is long limit near that limit of described back-up ring side.
In one preferred embodiment of this utility model, a width of 0.5 ~ 3cm in bottom of described water swelling rubber ring.
In one preferred embodiment of this utility model, two distances enclosed between described water swelling rubber ring are 1 ~ 3cm.
The beneficial effects of the utility model are: this utility model one double-peak type water swelling rubber ring, it is compounded with, near the side of back-up ring, the water swelling rubber ring that two circles are parallel in rubber body, pipeline can be made when tubing itself exists tolerance and construction ground later stage soil property changes, meet water chance oil and can produce expansion, can ensure that pipeline has good sealing effectiveness, extend the service life of pipeline.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one preferred embodiment；
Fig. 2 is the cross sectional representation of preferred embodiment shown in Fig. 1；
In accompanying drawing, the labelling of each parts is as follows: 1, rubber body, and 2, water swelling rubber ring, 3, back-up ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Referring to Fig. 1 and Fig. 2, this utility model embodiment includes:
A kind of double-peak type water swelling rubber ring, including cylindrical rubber body 1, is provided with back-up ring 3 in one end of rubber body 1, and back-up ring 3 is positioned at the inner side of rubber body 1, needs to connect fixing tubing for positioning, is allowed to difficult drop-off or displacement.It is compounded with the parallel water swelling rubber ring of two circles 2 in back-up ring 3 side of rubber body 1, the cross sectional shape of water swelling rubber ring 2 is triangle, triangle is long limit near that limit of back-up ring 3 side, make rubber ring convenient installation when pipe fitting being carried out seal construction, generally there is in rubber body 1 that side of back-up ring, advance to the inside of docking pipe fitting, carry out seal construction.
A width of 0.5 ~ the 3cm in bottom of water swelling rubber ring 2, the distance between two circle water swelling rubber rings 2 is 1 ~ 3cm.
This utility model double-peak type water swelling rubber ring, rubber body 1 is the common positioning rubber material used by construction requirement, and the material being only combined water swelling rubber ring 2 thereon is hydro-expansive rubber.The hardness (shore A) of common positioning rubber material is 55 ~ 65, and hot strength (MPa) is not less than 3 MPa, breaks productivity ratio more than 200%；The hardness (shore A) of hydro-expansive rubber is 45 ~ 55, and hot strength (MPa) is not less than 3.5 MPa, breaks productivity ratio and is more than 300%, and volume expansion ratio is more than 200.
This utility model can make pipeline when tubing itself exists tolerance and construction ground later stage soil property changes, and meets water chance oil and can produce expansion, it is possible to ensures that pipeline has good sealing effectiveness, extend the service life of pipeline.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
