Abstract
Electromagnetic induction heating type aluminium-plastic pipe pipe fitting, there is at least one welding port, it is characterized in that: on the tube wall between the inner side surface and outer side surface of described welding port, be equipped with an annular groove inserted for aluminium-plastic pipe, and then make the tube wall of described welding port form an outer tube wall and an inner tubal wall; And a heating circle is installed with on the inner side surface of the outer tube wall bottom annular groove.The utility model is mainly used in the hot-melt adhesive paste of aluminium-plastic pipe, not only has ne-leakage, without advantages such as seal ring are aging, and the phenomenon that welding port can also be avoided because it crosses thermal fusion welding to damage this port internal structure occurs.
Description
Technical field
The utility model relates to a kind of aluminium-plastic pipe link, particularly a kind of aluminium-plastic pipe link being suitable for electromagnetic induction heating.
Background technique
Traditional plastic-aluminum pipe-line system is all adopt the card pressure of machinery or the Placement of socket joint, thus by the seal ring between link and aluminium-plastic pipe and then the object realizing ne-leakage.But along with its seal ring of change of time and/or temperature deterioration phenomenon can occur, thus cannot ensure the sealability of pipe-line system, and then produce the problem of pipe-line system seepage, the technology of plastic-aluminum conduits fused is arisen at the historic moment thus.
But as shown in Figure 1, existing conduits fused technology is only treat that two ports of welding heat to it, finally implements the docking of two ports more simultaneously.This welding mode can cause serious infringement to the internal structure of its welding port, so designing a kind of welding structure being applicable to the welding port of fusion techniques is need technical problem urgently to be resolved hurrily now.
Model utility content
The purpose of this utility model is the technical problem lacking the welding structure suitable with it in order to solve existing aluminium-plastic pipe conduits fused technology, and then provides a kind of aluminium-plastic pipe pipe fitting being suitable for electromagnetic induction heating type.
The technological scheme that the utility model technical solution problem adopts is:
Electromagnetic induction heating type aluminium-plastic pipe pipe fitting, has at least one welding port.Wherein, the tube wall between the inner side surface and outer side surface of described welding port is equipped with an annular groove inserted for aluminium-plastic pipe, and then makes the tube wall of described welding port form an outer tube wall and an inner tubal wall; And a heating circle is installed with on the inner side surface of the outer tube wall bottom annular groove.
By implementing technique scheme, the design of annular groove can make aluminium-plastic pipe before welding in direct inserting pipe elements, thus lays a good foundation for deformation does not occur its welding port internal structure in fusion process.Secondly, electromagnetic induction heater can make the aluminium lamination of heating circle and aluminium-plastic pipe inside generate heat, and the outer plastic layer near generate heat circle periphery and aluminium lamination, inner plastic layer then change molten state into, and final pipe fitting is together with aluminium-plastic pipe hot melt.Not only can not there is deformation in such welding port inside, but also improve the sealing of welding port, thus make its this place and pipeline be provided with the effect of same equivalent life.
In order to electromagnetic induction heater can be allowed to locate fast and accurately, the technical program is enclosed the side away from corresponding welding port in heating and be provided with an annular positioning groove on the outer side surface of outer tube wall.Such electromagnetic induction heater just can determine the wish heated perimeter on welding port fast and accurately.
In order to welding effect can be observed easily and efficiently, correspond to heating circle in the technical program and be provided with observation panel on the outer side surface of outer tube wall.
In fusion process, in order to better keep the structure of welding port inside, the technical program interference fit in described welding port has a stainless steel lining.Like this under the supporting effect of stainless steel lining, the phenomenon that welding port tube wall will be avoided because of overheated to produce deformation occurs.And stainless steel lining more preferably open type stainless steel lining.
In order to realize close-fitting effect between pipe fitting and aluminium-plastic pipe, the technical program annular recess is right-angled trapezium along the cutting plane of its depth direction.

In figure: 1. welding port, 2. electromagnetic induction heater, 3. aluminium-plastic pipe, 11. annular grooves, 12. outer tube walls, 13. inner tubal walls, 14. heating circles, 15. stainless steel linings, 16. annular positioning grooves, 17. observation panels, 31. outer plastic layers, 32. aluminium laminations, 33. inner plastic layers.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Electromagnetic induction heating type aluminium-plastic pipe pipe fitting, it has at least one welding port one.This welding port one place is by the position of hot-melt adhesive paste between pipe fitting and aluminium-plastic pipe 3 or between aluminium-plastic pipe 3 and aluminium-plastic pipe 3; The quantity of its welding port one is determined by needing the number of the aluminium-plastic pipe 3 connected.
Electromagnetic induction heating type aluminium-plastic pipe pipe fitting as shown in Figure 2 and Figure 3, this pipe fitting has two welding port ones, tube wall between the inner side surface and outer side surface of each welding port one is equipped with an annular groove 11 inserted for aluminium-plastic pipe 3, thus makes the tube wall of its pipe fitting have an outer tube wall 12 and an inner tubal wall 13.Meanwhile, on the inner side surface of the outer tube wall 12 bottom annular groove 11, a heating circle 14 is also installed with.The design of above-mentioned annular groove 11 avoids and makes because its tube wall is overheated this welding port one inside that deformation occurs when welding.And the preferred structure of its annular groove 11 can be right-angled trapezium along the cutting plane of its depth direction.Secondly, in order to better keep the structure of welding port one inside, can also in this welding port one interference fit one stainless steel lining 15, thus by the supporting effect of stainless steel lining 15, and then keep original shape and structure of its welding port one inside.This stainless steel lining 15 can be open type stainless steel lining.
Heating circle 14 away from corresponding welding port one side and on the outer side surface of outer tube wall 12, be also provided with an annular positioning groove 16.This annular positioning groove 16 can allow electromagnetic induction heater 2 implement to locate fast and accurately to for heating position, thus improves the rate of heat addition.
In order to facilitate, easily examine welding effect, heating circle 14 can also be corresponded on the outer side surface of outer tube wall 12, be provided with observation panel 17.In fusion process, heating circle 14 starts heating in electromagnetic induction condition, thus makes the plastics around heating circle 14 change molten state into, and then makes to cave in bottom observation panel 17, realizes the object detecting, check thus.If therefore see there is recessed phenomenon bottom observation panel 17, this illustrates that welding effect is now more satisfactory; If do not have recessed phenomenon to occur, at this moment operator is in requisition for proceeding welding, until there is recessed phenomenon bottom observation panel 17.
Before welding, aluminium-plastic pipe 3 is inserted in annular groove 11, open the electromagnetic induction heater 2 be enclosed within welding port one afterwards, this heater can make the aluminium lamination 32 in heating circle 14 and aluminium-plastic pipe 3 produce a large amount of heats, and then make the outer plastic layer 31 around heating circle 14 and near aluminium lamination 32, inner plastic layer 33 all changes molten state into, thus make pipe fitting and aluminium-plastic pipe 3 welding at a place, and then achieve welding port one place ne-leakage, without the aging beneficial effect of seal ring.
