Abstract
A double-cone sealing pipe joint, wherein at least two connecting ends are provided on the plastic pipe body; a pipeline limiting step is positioned in the inner chamber of each connecting end; the conical surfaces are provided on the outer end of each inner chamber and connecting external threads are made on the external pipe wall of each inner chamber; the outer cover of the connecting ends and the inner side of the outer cover are provided with scalene conical surfaces and connecting internal threads; the double-cone sealing ring is installed between each connecting end and the scalene conical surface of the outer cover. The utility model has the advantages of: simple structure, convenient installation, secured and reliable use and excellent sealing effect etc.
Description
The utility model relates to a kind of pipe coupling, particularly relates to a kind of pipe joint that is provided with two connecting ends at least.
The pipe coupling of generally using at present is to adopt the structure that is threaded, and this structure need be rotated pipe fitting or joint to the quality requirement height of material during installation, complex operation, and inefficiency, the long-time use, because of screw threads for fastening, corrosion sometimes.Problems such as therefore, change, inconvenient maintenance, some plastic fittings in the recent period, film metal pipe fitting be with being threaded, but still have poor reliability, and inconvenience is installed, and sealing effect is undesirable.
The purpose of this utility model provides the be threaded pipe joint of pipeline of a kind of nothing, and installment work is simplified, and convenient maintenance and replacement is saved cost, wide adaptability.
The utility model is realized as follows: body made of plastic is provided with at least two connecting ends, in connecting end, be provided with the conical surface with the pipeline limited step and be connected outside thread, the enclosing cover inboard of connecting end is provided with the conical surface and is connected internal thread, between the conical surface that the conical surface that is provided with in the connecting end inboard and enclosing cover inboard are provided with bipyramid face seal circle is installed.Laying according to pipeline requires the shape of its connecting end that difformities such as "T"-shaped are arranged.After the pipeline connection part puts enclosing cover and seal ring during installation, directly pipeline is inserted in the connecting port, being threaded with the internal thread of connecting end outside thread and enclosing cover simultaneously gets final product.
The utlity model has advantages such as simple in structure, esy to use, safe and reliable, low cost of manufacture, good sealing effect.
Following structure accompanying drawing and example describe in further detail the utility model.
Fig. 1, cross-sectional view of the present utility model.
Fig. 2, side schematic view of the present utility model.
The cross-sectional view of Fig. 3, the utility model seal ring.
The structural representation of Fig. 4, the utility model seal ring.
Two connecting ends are set on the plastic tube body 1 in Fig. 1 and Fig. 2 at least, the both sides of plastic tube body 1 are provided with connecting end 2 and connecting end 3, on the center line Vertical direction of connecting end 2 and connecting end 3 connecting end 4 is set, connecting end 2 and connecting end 3 inner chambers respectively are provided with pipeline limited step 8, the inner chamber outer end is provided with the conical surface 9, the inner chamber outer tube wall is provided with and connects outside thread 14, the enclosing cover 5 of connecting end respectively is provided with the conical surface 10 and is connected internal thread 13 with the inboard of enclosing cover 6, between each the connecting end conical surface and the enclosing cover conical surface seal ring 12 is installed, seal ring 12 compresses the outer surface of the pipeline 11 of each connecting end.The inside of connecting end 4 and enclosing cover 7 is provided with the identical inner structure of above-mentioned connecting end 2 and enclosing cover 5 equally.
At this moment, the center line of connecting end 2 and connecting end 3 is point-blank.The center line of connecting end 2 and connecting end 4 is vertical mutually.Bipyramid face seal circle 12 inside left are provided with protruding ring 15 in Fig. 3 and Fig. 4, and the right side is provided with protruding ring 17, and the center portion is provided with depression ring 16, and seal ring 12 outer left side are provided with the conical surface 18, and the right side is provided with the conical surface 19.The plastic tube body that the utility model proposes 1 and each connecting end with and outside thread, each enclosing cover and internal thread be to be injection molded into one.
