Abstract
The utility model belongs to the field is connected to the thin wall stainless steel, especially discloses a nonrust steel pipe connection structure of plain type thin wall, the utility model provides a simple structure, installation be convenient, low cost, the high nonrust steel pipe connection structure of plain type thin wall of good, the anti pull strength of sealing performance swiftly, the technical scheme who adopts: including being cylindric pipe fitting and tubular product, external diameter and pipe fitting internal diameter that the internal diameter of pipe fitting is greater than tubular product suit with the tubular product external diameter, and tubular product is pegged graft in the pipe fitting, and tubular product and pipe fitting combination department are provided with and still are provided with the spill clamping ring on pipe fitting and the tubular product of adhesive layer and combination department.
Description
technical field:
The utility model belongs to thin-wall stainless steel connection area, particularly relates to a kind of plain type thin-wall stainless steel pipe connecting structure.
background technique:
Thin-wall stainless steel has safety durable, environmental protection sanitary, reasonable price, the excellent combination property such as luxurious attractive in appearance, has been widely used in building water supply and direct drinking pipeline.Well known, the trunk of pipeline is combined by tubing, and tubing dependence pipe fitting is formed by connecting, and at present, conventional has following several Placement, but these Placements all exist different shortcomings.
1 is compression type linkage structure: by tubing inserting pipe elements, then by fastening nuts, seal ring is compressed and plays seal action, this Placement installation procedure is many, cost is high, and during installation, tubing needs with special tool bulging and screw thread also needs to weld with pipe fitting body in advance; 2 is welding type linkage structures: by tubing inserting pipe elements, then in splicing position welding, and this Placement construction trouble, scene must make electricity consumption, the spot temperature of its welding is high easily there is poor chromium phenomenon, and solution treatment can not be carried out again in scene, and welding part is got rusty easily; 3 is simple adhesive connections, this mode is that internal taper hole is made in the joint of pipe fitting, the connection mouth of stainless steel pipe is made outer cone mouth simultaneously, in the internal taper hole again sealant being spread upon respectively link and on the surface of the outer cone mouth of stainless steel pipe, finally the outer cone mouth of stainless steel pipe is inserted in the internal taper hole of link, realize their connection.This Placement can solve the problem of aging of seal ring, but tension pull out force between them is also not ideal, and join strength is not as two kinds of modes above.All there is different shortcomings in above-mentioned several Placement, well can not realize the connection of pipe fitting and tubing.
model utility content:
The utility model overcomes the deficiency that prior art exists, and solves prior art Problems existing, aims to provide simple, the quick for installation convenience of a kind of structure, the plain type thin-wall stainless steel pipe connecting structure that with low cost, good seal performance, anti-drawing strength are high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: plain type thin-wall stainless steel pipe connecting structure, comprise pipe fitting cylindrically and tubing, the internal diameter of described pipe fitting is greater than the external diameter of tubing and pipe fitting internal diameter and tube outer diameter adapt, tubing is plugged in pipe fitting, and tubing and pipe fitting junction are provided with adhesive layer and the pipe fitting of junction and tubing are also provided with spill trim ring.
Further, described pipe fitting is preset with fixed point, after tubing and pipe fitting grafting, tubing termination contacts with fixed point.
Further, described pipe fitting for leading directly to shape pipe fitting or being elbow-shaped pipe fitting, or is threeway shape pipe fitting.
Further, described adhesive layer is anaerobic adhesive.
Further, described pipe fitting and tubing are stainless-steel thin-wall pipe.
The utility model compared with prior art has following beneficial effect: the internal diameter of the utility model pipe fitting is greater than the internal diameter of tubing, the quick grafting of tubing and pipe fitting can be realized like this, and columnar pipe fitting and tubing are processed simpler relative to originally adhered conical connecting head, sanction material and fixed point two procedures is only needed to complete, can be cost-saving in a large number.And pipe fitting is connected with tubing by adhesive-layer by the utility model, adhesive layer realizes tubing and seals with pipe fitting and be connected, and spill trim ring promotes sealability and the tensile strength of tubing and pipe fitting further.This Placement has overturned traditional seal ring seal form, fundamentally solves the problem of aging of seal ring.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described in more detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end-face structure schematic diagram of pipe fitting.
In figure: 1 is pipe fitting, 2 is tubing, and 3 is adhesive layer, and 4 is spill trim ring, and 5 is fixed point.
embodiment:
As shown in Figure 1 and Figure 2, plain type thin-wall stainless steel pipe connecting structure, comprise pipe fitting 1 cylindrically and tubing 2, the internal diameter of described pipe fitting 1 is greater than the external diameter of tubing 2 and pipe fitting 1 internal diameter and tubing 2 external diameter adapt, tubing 2 is plugged in pipe fitting 1, and tubing 2 and pipe fitting 1 junction are provided with adhesive layer 3 and the pipe fitting 1 of junction and tubing 2 are also provided with spill trim ring 4.
When pipe fitting 1 is connected with tubing 2, first on the outer wall of tubing 2 and the inwall of pipe fitting 1, apply anaerobic adhesive, anaerobic adhesive wants uniform application, then by tubing 2 and pipe fitting 1 grafting, internal diameter due to pipe fitting 1 is greater than the external diameter of tubing 2, anaerobic adhesive can form adhesive layer 3 between tubing 2 outer wall and pipe fitting 1 inwall, pipe fitting 1 is connected with tubing 2 and realizes pipe fitting 1 and seal with tubing 2 joint by adhesive layer 3 anoxic rapid solidification, extrudes spill trim ring 4 after tubing 2 and pipe fitting 1 grafting with special tool at pipe fitting 1 and tubing 2 junction.Spill trim ring 4 promotes sealability and the join strength of tubing 2 and pipe fitting 1 further.
In order to limit the distance in tubing 2 inserting pipe elements 1, described pipe fitting 1 is preset with fixed point 5, after tubing 2 and pipe fitting 1 grafting, tubing 2 termination with fix a point 5 to contact.
In addition, described pipe fitting 1 is straight-through shape pipe fitting 1, or is elbow-shaped pipe fitting 1, or is threeway shape pipe fitting 1.This linkage structure can be applied in different pipe fitting 1 form, and described pipe fitting 1 and tubing 2 are stainless-steel thin-wall pipe.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
