Abstract
The utility model belongs to pipe joint technical field, is specifically related to a kind of novel telescopic joint.There is a rib of demarcating the centre that the utility model mainly solves existing slip joint internal surface, inconvenient problem with use when causing repairing pipeline.The technical solution of the utility model is: a kind of novel telescopic joint, comprise slip joint body, the upper end mouth of pipe of described slip joint body is greater than the lower end mouth of pipe, the top outer surface of the upper end mouth of pipe is provided with outside thread, the upper end mouth of pipe is provided with nut circle, described nut circle is mated with outside thread by the internal thread of its internal surface and is connected, and is provided with seal ring between slip joint body and nut circle, wherein: the internal surface of described slip joint body is smooth structure.The utility model adopts technique scheme, and the right being positioned at leather packing in slip joint internal surface is smooth structure, in the middle of internal surface, does not arrange a rib specially, is convenient for people to use when repairing pipeline.
Description
Technical field
The utility model belongs to pipe joint technical field, is specifically related to a kind of novel telescopic joint.
Background technique
Current PVC is widely used in the drainage building boundary, and this material is quick and easy for installation, but easily damages.Time master worker installs new sewerage, market there are ready-made pipe and pipe fitting, when the serious adapter road that expands with heat and contract with cold with slip joint, a rib of demarcating is had in the middle of this slip joint, can ensure that pipeline two surface of contact by connecing on average insert like this when pipe laying, there will not be many few phenomenons on one side on one side, this slip joint uses when new pipe laying better.But when repairing drainage pipeline, this slip joint is just not handy.Because when repairing drainage pipeline, be all fixed in building cannot move by the pipe ends of repairing, the augular offset that amplitude is very little has also been only had to be difficult to repair even if break with strength.Existing slip joint is used to be all generally the length ratio broken parts of the pipe saw that will cover broken parts being shorter than a pipe collar when repairing pipeline, then firmly pipe is broken, its angle that staggers is made to inject slip joint, respectively to upper and move down slip joint and just can catch, repair with this pipe fitting and often occur that the ginseng junction that pipe puts in pipe collar and slip joint only has seldom a bit, many on one side while less, sometimes also may other positions of pipeline be broken bad, very unreliable.
Summary of the invention
The utility model has a rib of demarcating mainly for the centre of existing slip joint internal surface, and inconvenient problem with use when causing repairing pipeline, provides a kind of novel telescopic to save.
The utility model is the technological scheme taked that solves the problem:
A kind of novel telescopic joint, comprise slip joint body, the upper end mouth of pipe of described slip joint body is greater than the lower end mouth of pipe, the top outer surface of the upper end mouth of pipe is provided with outside thread, the upper end mouth of pipe is provided with nut circle, described nut circle is mated with outside thread by the internal thread of its internal surface and is connected, and is provided with seal ring between slip joint body and nut circle, wherein: the internal surface of described slip joint body is smooth structure.
The utility model adopts technique scheme, the internal diameter of telescopic machine is a bit larger tham by the external diameter repairing sewerage, during use, the utility model slip joint is by can be movable on the sewerage repaired, the internal surface of another slip joint is unified smooth surface, a rib is not set specially in the middle of internal surface, is convenient for people to use when repairing pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of novel telescopic joint, comprise slip joint body 1, the upper end mouth of pipe of described slip joint body 1 is greater than the lower end mouth of pipe, the top outer surface of the upper end mouth of pipe is provided with outside thread 2, the upper end mouth of pipe is provided with nut circle 3, described nut circle 3 is mated with outside thread 2 by the internal thread of its internal surface and is connected, and seal ring 4 is provided with between slip joint body 1 and nut circle 3, the internal surface of described slip joint body 1 is smooth structure.
Using method:
Illustrate to repair vertical tube:
1, first take slip joint being made a gesture of measuring by the pipe repaired, estimate that place pencil that pipe puts in slip joint half is being done a mark by the pipeline repaired;
2, the nut of slip joint and seal ring are backed out be enclosed within the pipe of broken parts, slip joint main body is enclosed within by the pipeline repaired and set mark is exposed in activity downwards, more than its mark, ginseng connects position and spreads glue, movable telescopic joint is moved along pipeline, just expose the mark done in advance, seal ring and nut screwing clamping after the glue solidifies.
Claims (1)
