Abstract
The utility model discloses a kind of pipe coupling, comprise joint body, the passage of the middle part of described joint body for connecting, is provided with sealing engagement portion in the vias inner walls of described joint body side; In described passage intermediate inner wall, be provided with limit position part; Described sealing engagement portion comprises that cross section is followed successively by outer bulge loop and the interior scrobicular ring of outer convex arc and imploded arcs formation, and described limit position part is around the inwall limited ring of a week, and described limited ring is that cross section is the outer bulge loop of rectangular boss.The utility model provides a kind of pipe coupling, has advantages of simple in structure, easy to operate, good seal performance, can realize the quick of pipeline and connect without leaking, and can limit the access size of connecting tube simultaneously, strengthens the accuracy that pipeline is connected.
Description
Technical field
The utility model relates to a kind of joint, particularly relates to a kind of pipe coupling that the pipe of fluid input and outlet is coupled together.
Background technique
When laying pipeline, keep away the unavoidable pipeline connection problem that there will be, therefore between two pipelines, just need to manually connect, if at indoor and pipe diameter while not being very large, all generally by hot connecting, but this hot connecting needs skilled labour to carry out, and the quality connecting is also difficult to guarantee; If be positioned at outdoorly, and the place connecting do not have power supply, and hot connecting cannot be used, and can only connect by joint, but present joint connects the problem that is difficult to ensure the quality of products that all exists.
Model utility content
Main purpose of the present utility model is, overcomes deficiency of the prior art, and a kind of pipe coupling of new structure is provided, and is specially adapted to carry out without leaking, connect fast.
That technical problem to be solved in the utility model is to provide is simple in structure, easy to operate, the pipe coupling of good seal performance, can realize without leaking, connecting fast, and have the value in industry.
The utility model the technical problem that will further solve be to realize the restriction of connecting tube access size, avoid accessing the long or too short of pipeline, strengthen the accuracy that pipeline is connected.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A pipe coupling, comprises joint body, and the passage of the middle part of described joint body for connecting is provided with sealing engagement portion in the vias inner walls of described joint body one side.
The utility model is further set to: in the vias inner walls of described another side of joint body, be also provided with sealing engagement portion.
Adopt technique scheme, the sealing that can realize pipe coupling by arranging of sealing engagement portion connects without leaking, and guarantees the validity that pipeline connects.
The utility model is further set to: in described passage intermediate inner wall, be provided with limit position part.
Described limit position part carries out internal zone dividing by pipe coupling, and the length of access pipeline is limited, and realizes the accuracy that pipeline is connected, and avoids the inhomogeneous of two access pipeline.
The utility model is further set to: described sealing engagement portion comprises that cross section is followed successively by outer bulge loop and the interior scrobicular ring of outer convex arc and imploded arcs formation.
The utility model is further set to: described sealing engagement portion comprises that cross section is followed successively by outer bulge loop and the interior scrobicular ring of rectangular boss and rectangular recess formation.
Described sealing engagement portion comprises outer bulge loop and interior scrobicular ring, and cross section is outer bulge loop and interior scrobicular ring that outer convex arc and imploded arcs form, and its smoothness is effectively guaranteed, the Sealings such as more convenient placement seal washer, and the sealing effect of inserting after Sealing is better.
The utility model is further set to: described limit position part is two limiting stoppers, and described limiting stopper is distributed in respectively the diameter two ends of passage.
The utility model is further set to: described limit position part is that described limited ring is that cross section is the outer bulge loop of rectangular boss around the inwall limited ring of a week.
Described limit position part is limiting stopper or limited ring, and the spacing soundness of limited ring is better.
In sum, the technological scheme of a kind of pipe coupling of the utility model, has advantages of simple in structure, easy to operate, good seal performance, can realize the quick of pipeline and connect without leaking, can limit the access size of connecting tube, strengthen the accuracy that pipeline is connected simultaneously.
Foregoing is only the general introduction of technical solutions of the utility model, and for clearer understanding technological means of the present utility model, below in conjunction with accompanying drawing, the utility model will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pipe coupling of the utility model;
Fig. 2 is the sectional view of a kind of pipe coupling of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figures 1 and 2, a kind of pipe coupling, comprises joint body 1, the passage 2 of the middle part of described joint body 1 for connecting; In the vias inner walls of described joint body 1 one sides, be provided with sealing engagement portion, described sealing engagement portion comprises that cross section is followed successively by outer bulge loop 3 and the interior scrobicular ring 4 of outer convex arc and imploded arcs formation; In the intermediate inner wall of described passage 2, be provided with limit position part, described limit position part is around the inwall limited ring of a week 5, and described limited ring 5 is that cross section is the outer bulge loop of rectangular boss.
Compared with prior art, the beneficial effects of the utility model are, outer bulge loop 3 and interior scrobicular ring 4 the smoothness that has guaranteed sealing engagement portion is set, the convenient Sealings such as seal washer of placing, the sealing effect of inserting after Sealing is better; And arranging of limited ring 5 realizes connecting tube access size and limited, avoid accessing the long or too short of pipeline, strengthen the accuracy that pipeline is connected.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
