Abstract
A pipeline connecting piece for stainless steel thin-walled pipe comprises a connecting body, a gluing layer and a pipe to be connected, wherein both the outer circle and the inner bore at the end head of the connecting body adopt a step-shape with thick end heads and thin middle part, the diameter of the inner bore is 0.2mm to 0.5mm larger than that of the outer circle of the pipe to be connected, and the gluing layer formed by anaerobic adhesive is coated on the surface of the inner bore. The end part of the pipe to be connected is inserted in the inner bore so as to realize the connection of the pipe. The pipeline connecting piece has the advantages of simple construction, convenient operation, saved pipe cost and mounting man-hour expense, strong drawing resistance capability, reliableconnection and excellent air tightness, and is especially suitable for the connection of thin-walled stainless steel pipe in water-supply system and fuel gas system.
Description
Affiliated technical field
The utility model relates to a kind of interconnective link of stainless steel thin-wall tubing that is used for realizing.
Background technique
At present, the Placement between the existing stainless steel thin-wall tubing has following several: have plenty of employing welding type between link and the stainless steel thin-wall tubing is connected.This welding type Placement, the construction trouble, the scene must make electricity consumption, the poor chromium phenomenon of the high appearance easily of the position temperature of its welding, solution treatment can not be carried out again in the scene, and the welding part is got rusty easily.And this welding connecting mode cost is higher; Have plenty of and seal ring is set in link and causes the link and the plastic deformation of pipe fitting oral area to finish being connected between link and the stainless steel thin-wall tubing by extruding.The used seal ring of this Placement is the nitrile rubber seal ring, and its weatherability and rebound elasticity are all relatively poor, and seal ring is aging easily, and time one is long to cause seepage probably, can't guarantee that pipe-line system does not have to leak for a long time to take place; Also have plenty of and adopt simple bonding way, this mode is that the attachment hole of link is made internal taper hole, simultaneously the connection mouth of stainless steel pipe is made the outer cone mouth, again sealant is spread upon respectively on the surface of outer cone mouth of the internal taper hole of link and stainless steel pipe, outer cone mouth with stainless steel pipe inserts in the internal taper hole of link at last, realizes their connection.Though this Placement has solved the problem of aging of seal ring, the tension pull out force between them is also not ideal, and join strength is not as the front dual mode.Therefore the Connecting format between stainless steel thin-wall tubing remains further to be solved.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provides a kind of construction simple, and is easy to operate, tension pull out force height, connect reliable, the pipe joint of favorable sealing property.
The purpose of this utility model realizes by following technical measures: this pipe joint includes connecting body, adhesive layer and is connected tubing, wherein all to be the termination thin step-like in the middle of thick for the cylindrical of connecting body end and endoporus, and the diameter of bore of its end is than the big 0.2mm～0.5mm of the outside diameter that is connected tubing.Also on the bore area of the termination of connecting body, be coated with anaerobic adhesive in addition and form adhesive layer.And then will be connected in the termination endoporus of tubing insertion connecting body, the step in its termination endoporus can stop the continuation that is connected tubing to be inserted, and plays the axially locating effect.Impose compacting with a pressing mold to the position, termination of connecting body at last, make the termination cylindrical of connecting body produce plastic deformation, form regular polygon shape or recessed toroidal, and be connected the tubing engagement and be riveted together.Adhesive layer anoxic in the pipe joint that presses is solidified rapidly, plays sealing and bonding effect, thereby finishes the connection to pipe fitting.
Connecting body described in the utility model is the connecting body that leads directly to, or the connecting body of elbow-shaped, or the connecting body of threeway shape.
The utility model beneficial effect compared with prior art be construction simple, easy to operate, save tubing cost and installation work-hour expense greatly.And its join strength is very high, and sealing is good especially, the connection of the thin-wall stainless steel tubing in very suitable water supply system, the gas burning system.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: this pipe joint is by connecting body 1, adhesive layer 2 and is connected tubing 3 and constitutes.The profile of connecting body 1 is the cylinder of straight-through shape, and it is thin step-like in the middle of thick that the cylindrical of its end and endoporus all are the termination, and the diameter of bore of its end is than the big 0.3mm of the outside diameter that is connected tubing 3.Also anaerobic adhesive is spread upon in addition on the termination bore area of connecting body 1, form adhesive layer 2.The termination that is connected tubing 3 is inserted in the termination endoporus of connecting body 1, and the step in its termination endoporus can play the axially locating effect, and resistance is connected the continuation of tubing 3 and inserts.After being connected tubing 3 insertions, impose compacting with a pressing mold to the position, termination of connecting body 1 cylindrical again, allow the termination cylindrical of connecting body 1 produce plastic deformation, difference according to the pressing mold shape, form the regular polygon shape or form recessed toroidal at the termination of connecting body 1 outer round surface, thereby with the connection mouth engagement riveted joint that is connected tubing 3.Adhesive layer 2 anoxic in the pipe joint that presses is solidified rapidly, plays sealing and bonding effect, so finish the connection to pipe fitting.
Change the connecting body of elbow-shaped or the connecting body of threeway shape into as the connecting body 1 that needs only straight-through shape among the above embodiment, and other structure is constant, just can constitute other two kinds of embodiments.
Claims (2)
1, a kind of pipe joint of stainless-steel thin-wall pipe, include connecting body (1), adhesive layer (2) and be connected tubing (3), it is thin step-like in the middle of thick to it is characterized in that the cylindrical of connecting body (1) end and endoporus all are the termination, and the diameter of bore of its end is than the big 0.2mm～0.5mm of outside diameter that is connected tubing (3), also on the termination bore area of connecting body (1), be coated with anaerobic adhesive in addition and form adhesive layer (2), being connected tubing (3) is to be inserted in the termination endoporus of connecting body (1), is suppressed with regular polygon shape or recessed toroidal afterwards on the cylindrical at connecting body (1) position, termination.
