Abstract

The utility model relates to pipe joint or pipe fitting technical field, discloses a kind of breakdown joint that can adapt to pipeline extension, the clamping flange sheet comprising flange cylindrical shell and dock with its one end; Connected by clamping bolt between described flange cylindrical shell and described clamping flange sheet, and be provided with O-ring seal between the interface of described flange cylindrical shell and described clamping flange sheet; Described flange cylindrical shell is provided with assembly connecting bolt away from one end of described clamping flange sheet.The beneficial effects of the utility model are: can carry out rapid rush-repair to the pipeline of fracture, substantially reduce the time of pipe first-aid; The O-ring seal arranged can adapt to the flexible of pipeline automatically.

Description

A kind of breakdown joint that can adapt to pipeline extension
Technical field
The utility model relates to pipe joint or pipe fitting technical field, especially a kind of breakdown joint that can adapt to pipeline extension.
Background technique
At present, known pipeline burst repairing step is: 1. excavate (find out and damage pipeline); 2. dig welder and operate hole; 3. the pipeline damaged is cut; 4. be connected with the pipeline of identical material with equal length, same size.The method connected has direct welding (metal material), Flange joint and sleeve connection (metallic conduit and concrete duct).Sleeve connection (water pipe) also needs to add asbestos rope and uses jet cement urgent again, could water flowing after curing time arrives.4. walk the especially, the welder muddy ground below pipeline that sometimes needs to couch could work.Above-mentioned no matter which kind of emergency repair method, all needs longer emergency repair time.
Model utility content
Technical problem to be solved in the utility model be to provide a kind of can rapid rush-repair and automatically adapt to the joint of pipeline extension, substantially reduce the time of pipe first-aid.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of breakdown joint that can adapt to pipeline extension, the clamping flange sheet comprising flange cylindrical shell and dock with its one end; Connected by clamping bolt between described flange cylindrical shell and described clamping flange sheet, and be provided with O-ring seal between the interface of described flange cylindrical shell and described clamping flange sheet; Described flange cylindrical shell is provided with assembly connecting bolt away from one end of described clamping flange sheet.
The beneficial effects of the utility model are: be enclosed within two the pipeline broken ends needing to be connected respectively by flange cylindrical shell, clamping flange sheet, O-ring seal and the connector assembly that clamping bolt is assembled into by two, afterwards two connector assembly assembly connecting bolts are coupled together, and then the pipeline of fracture is reconnected, make repairing work very convenient, accomplish, to the rapid rush-repair of pipeline, greatly to save emergency repair time; In order to adapt to the feature that pipeline expands with heat and contract with cold, utilizing the resiliently deformable of O-ring seal to be close to pipeline and sealing, when pipeline produces axial stretching and radial expansion, O-ring seal can produce resiliently deformable and automatically adapt to the flexible of pipeline.
On the basis of technique scheme, the utility model can also do following improvement.
Further, the one end of docking on described flange cylindrical shell, with described clamping flange sheet is provided with expanding short tube, the one end of docking on described clamping flange sheet, with described flange cylindrical shell is provided with boss, and described expanding short tube and described boss shape and structure match and can mutually be docking together; O-ring seal is provided with between described expanding short tube and the contact end face of described boss.
The beneficial effect of above-mentioned further scheme is adopted to be that the expanding short tube of flange cylindrical shell can play the effect of location to O-ring seal and the boss of clamping flange sheet be played to the effect of guiding; Boss plays the effect of clamping to O-ring seal.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
In accompanying drawing, the list of parts representated by each label is as follows:
1, flange cylindrical shell, 2, O-ring seal, 3, clamping flange sheet, 4, clamping bolt, 5, pipeline, 6, assembly connecting bolt, 7, expanding short tube, 8, boss.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
In an embodiment, as shown in Figure 1, a kind of breakdown joint that can adapt to pipeline extension, the clamping flange sheet 3 comprising flange cylindrical shell 1 and dock with its one end; Connected by clamping bolt 4 between described flange cylindrical shell 1 and described clamping flange sheet 3, and be provided with O-ring seal 2 between the interface of described flange cylindrical shell 1 and described clamping flange sheet 3; Described flange cylindrical shell 1 is provided with assembly connecting bolt 6 away from one end of described clamping flange sheet 3.
The one end of docking on described flange cylindrical shell 1, with described clamping flange sheet 3 is provided with expanding short tube 7, the one end of docking on described clamping flange sheet 3, with described flange cylindrical shell 1 is provided with boss 8, and described expanding short tube 7 matches with described boss 8 shape and structure and can mutually be docking together; O-ring seal 2 is provided with between described expanding short tube 7 and the contact end face of described boss 8.Described boss 8 inserts in expanding short tube 7, serves the effect of guiding and the pressuring action to O-ring seal 2 to boss 8; What O-ring seal 2 was positioned at expanding short tube 7 and boss 8 contacts end, well can be located, can not lose the effect of sealing because of distortion.
Described flange cylindrical shell 1, O-ring seal 2, clamping flange sheet 3 and clamping bolt 4 are assembled into a connector assembly.Working principle of the present utility model is: be enclosed within by a connector assembly on a broken end of the pipeline 5 that need connect, tighten whole clamping bolt 4 again, at this moment O-ring seal 2 is extruded generation resiliently deformable, one side is close to an inner side surface of the expanding short tube 7 on flange cylindrical shell 1, another side is close to again on the outer tube surface of the pipeline 5 needing connection, forms the sealing to tube fluid medium; Another broken end of pipeline 5 repeats above-mentioned work, finally two connector assemblies is connected the repairing connection work just completing and resolve pipe with assembly connecting bolt 6.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
