Description
Technical field
The utility model relates to a kind of pipeline of carrying for mine and earth's surface liquid state, gaseous substance, and the particularly connection of pipeline, belongs to industrial and mineral material to be mined transportation art.
Background technique
Carry for liquid, gaseous state now, owing to considering the unitized of pipeline, conventionally adopt: body two threading, more adjacent pipeline opening is connected so that pipeline has sufficient length with tapped joint, or in order to reach same object employing welding manner connection.Two kinds of modes are being used scene all to need more complicated professional tool or soldering set successfully to connect, but, because adopt transition joint to connect, make can not realize slitless connection between pipeline docking port, due to the existence in gap, not only increase the moving resistance of transportation of substances in pipe, and in use also can be subject to many limitations.Adopt welding manner butt welded seam to have relatively high expectations, and easily occur the situations such as Kaifeng sealing-off.Two kinds of modes all exist because tensile force is low, sealing is not strong etc. and cause the phenomenons such as body leakage, bring hidden danger to safety in production.
Model utility content
The problem that the utility model exists for current traditional delivery pipe body joint, provides connected type oil and the direct-connected button of mine pipeline, to realize easy construction, and good airproof performance, the object that reliability is high.
The technical scheme in the invention for solving the technical problem is:
This connected type oil and the direct-connected button of mine pipeline, structure comprises: the pin thread of cylinder structure and box, the end of the pin thread matrix of described pin thread is provided with pin thread annular extension, pin thread annular extension and pin thread matrix connecting part form outer shoulder, the two ends of the outside turning surface of pin thread annular extension are respectively pin thread column external sealed face, and middle part is provided with pin thread outside thread; The matrix end of described box is provided with ring cavity part in box, in box, ring cavity part and box matrix joint form interior shoulder, in box, the two ends of the inner side turning surface of ring cavity part are respectively the box column inner sealing surface being sealed and matched with pin thread column external sealed face, and middle part is provided with the box internal thread that pin thread outside thread coordinates; Pin thread annular extension is tightened in the interior ring cavity part of box; Described pin thread matrix and box matrix have identical internal diameter.Because the two ends, connecting part of pin thread and box all adopt the combination of column sealing surface, and middle part adopts internal and external threads combination, to realize easy construction, and good airproof performance, the object that reliability is high.
Further, described pin thread outside thread and box internal thread all adopt buttress thread, to improve the intensity of connecting part of pin thread and box.
Further, described pin thread matrix and box matrix have identical external diameter, and to adapt to outside isometrical place, profile is consistent simultaneously, are conducive to the direct-connected button of production and processing and facilitate the construction of direct-connected button.
Further, the wall thickness of pin thread annular extension is the half of pin thread matrix wall thickness; In box, the wall thickness of ring cavity part is the half of box matrix wall thickness, can obtain so best intensity and good production and processing technology.
Compared with prior art, the utlity model has following advantage:
1. the utility model easy to operate connection that can conveniently realize pipeline simple in structure.
2. when meeting sealing, can improve pipe joint place operating mode, avoid occurring interface fracture.
3. simple in structure, fabricating cost is low, and application is wide.
Brief description of the drawings
Fig. 1 is the utility model overall diagram (partly cuing open).
In figure: 1 pin thread, 2 boxes, 3 outer connecting parts, 4 interior connecting parts, 5 chamferings, 6 threaded joints, 7 primary sealing areas, 8 secondary sealing areas.
Embodiment
As shown in the figure.This connected type oil and the direct-connected button of mine pipeline, comprise the pin thread 1 and the box 2 that are connected, and described pin thread 1 and box 2 are cylinder structure.
The end of the pin thread matrix of pin thread 1 is provided with pin thread annular extension, and pin thread annular extension and pin thread matrix connecting part form outer shoulder, and described outer shoulder coordinates with the end face of box 2; The two ends of the outside turning surface of pin thread annular extension are respectively pin thread column external sealed face, and middle part is provided with pin thread outside thread.
The matrix end of box 2 is provided with ring cavity part in box, and in box, ring cavity part and box matrix joint form interior shoulder, and described interior shoulder coordinates with the end face of pin thread 1; In box, the two ends of the inner side turning surface of ring cavity part are respectively the box column inner sealing surface being sealed and matched with pin thread column external sealed face, and middle part is provided with the box internal thread that pin thread outside thread coordinates.
Pin thread annular extension is tightened in the interior ring cavity part of box, after assembling, the end face of pin thread annular extension supports only on the interior shoulder of box 2, in box, the end face of ring cavity part supports only on the outer shoulder of pin thread 1, and form respectively outer connecting part 3 and connecting part, 4 two of interior connecting parts, form the sealing of three levels simultaneously, be positioned at column primary sealing area 7 and the column secondary sealing area 8 at two ends, and be positioned at the threaded joints 6 at middle part.Primary sealing area 7 and secondary sealing area 8 are by box column inner sealing surface and pin thread column external sealed face drive fit composition; Threaded joints 6 is realized by the sealing between internal thread and outside thread.Because the two ends, connecting part of pin thread and box all adopt the combination of column sealing surface, and middle part adopts internal and external threads combination, to realize easy construction, and good airproof performance, the object that reliability is high.
Length is consistent in the axial direction with ring cavity part in box for pin thread annular extension, and for ease of installing, at interior shoulder, place is provided with chamfering 5, to avoid installing situation not in place.
Pin thread matrix and box matrix have identical internal diameter, so that direct-connected button inwall is tending towards smooth, are conducive to reduce liquid flowing resistance.Pin thread matrix and box matrix also have identical external diameter simultaneously, and to adapt to outside isometrical place, profile is consistent simultaneously, are conducive to the direct-connected button of production and processing and facilitate the construction of direct-connected button.
Pin thread outside thread and box internal thread all adopt buttress thread, to improve the intensity of connecting part of pin thread and box.
The wall thickness of pin thread annular extension is the half of pin thread matrix wall thickness; In box, the wall thickness of ring cavity part is the half of box matrix wall thickness, makes the wall thickness such as whole pipeline in future, can obtain so best intensity and good production and processing technology.
For a tubing, one end can be set to pin thread structure, and the other end is set to box structure, and tubing connects and can connect in turn like this.
The above, be only embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of model utility.
