Abstract
The utility model discloses a joint of copper-aluminum welding pipe with external protecting device, which is a joint structure applied in the connection pipe of domestic air conditioner. The structure comprises a copper pipe, an aluminum pipe, a sleeve pipe and a coating. The copper pipe and the aluminum pipe are mutually sleeved and welded to form the copper-aluminum welding pipe joint, a segment of sleeve pipe is sleeved on the outer wall of the copper-aluminum welding pipe joint, the cooperating segment between the copper-aluminum welding pipe joint and the sleeve pipe is arranged with the coating. The sleeve pipe is made of engineering plastic or metal material, the coating is liquid high strength structural adhesive. The lateral cross section of the copper-aluminum welding pipe joint with outer protection device increases, and the flexural strength is high, the copper-aluminum welding pipe joint cannot be easily damaged by bending without cause during installation of the connection pipe of domestic air conditioner, thus greatly reduces the leakage possibility of the connection pipe of domestic air conditioner. The utility model has simple structure, easy realization and low cost for manufacture, thus can be widely used in structure improvement of a plurality types of domestic air conditioner.
Description
Technical field
The utility model relates to a kind of pipe joint, and specifically, it relates to a kind of welded stub connection with outer protective gear.
Background technique
The inside and outside unit of domestic air conditioner is connected by connecting tube, and the connecting tube of conventional design is full copper pipe.Current nonferrous metal resource is in short supply, and copper pipe holds at high price, and most air conditioner manufacturing enterprise comes the cost of production of digesting material rise in price by technological improvement.For example, prior art makes to be welded respectively by the aluminum pipe two ends full copper connecting tube the structure of copper pipe into, although the connecting tube of this structure has increased by two copper and aluminium welding Tube to tube fittingss, can satisfy the usage requirement of air conditioner equally.But, in the prior art, because of the copper aluminium weldability that matches poor slightly, copper and aluminium welding Tube to tube fittings resistance to flexure after the welding is not as good as full copper pipe height, copper and aluminium welding Tube to tube fittings place is flexible in the domestic air conditioner installation process, cause copper and aluminium welding Tube to tube fittings weld joint to form crackle, leak hidden danger, increased the accident rate and the maintenance cost of domestic air conditioner thus thereby form connecting tube.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, solves the technical barrier of copper and aluminium welding Tube to tube fittings resistance to flexure difference, proposes a kind of copper and aluminium welding Tube to tube fittings with outer protection unit, and this is simple in structure, easy to connect, resistance to flexure is high.
The utility model is achieved through the following technical solutions technical goal.
A kind of copper and aluminium welding Tube to tube fittings with outer protection unit, it is made of copper pipe, aluminum pipe, sleeve pipe and coating; Described copper pipe and aluminum pipe are nested to merge and are welded to form the copper and aluminium welding Tube to tube fittings; Improvements are: described cover pipe orifice and copper pipe, aluminum pipe external diameter nominal size are identical, and casing pipe sleeve is contained in copper and aluminium welding and connects; Be provided with coating between described sleeve pipe and the copper and aluminium welding Tube to tube fittings section of matching.
The said structure middle sleeve is made with engineering plastics or metallic material, and with between the copper and aluminium welding Tube to tube fittings matches, coating is a kind of liquid high-strength structural adhesives that is used for binding metal material and plastics to coating between sleeve pipe.
The utility model compared with prior art has following beneficial effect:
1, on copper and aluminium welding Tube to tube fittings outer wall, uses liquid high-strength structural adhesives bonding sleeve pipe, simple in structure, easy realization, few, the low cost of manufacture of materials;
2, the effective liquid high-strength structural adhesives of cover is bonded on the copper and aluminium welding Tube to tube fittings outer wall, formation is to the outer protection unit of copper and aluminium welding Tube to tube fittings, increased the long-pending and resistance to flexure of lateral cross section of this section effectively, this copper and aluminium welding Tube to tube fittings with outer protection unit is difficult for being reduced the possibility that the domestic air conditioner connecting tube leaks by crooked and damage without reason.
Description of drawings
Accompanying drawing 1 is the utility model structural profile schematic representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
A kind of copper and aluminium welding Tube to tube fittings with outer protection unit is the joint structure on the domestic air conditioner connecting tube, and this structure is made of copper pipe 1, aluminum pipe 3, sleeve pipe 2 and coating 4.Described copper pipe 1 and aluminum pipe 3 are nested to merge and are welded to form the copper and aluminium welding Tube to tube fittings, and sleeve pipe 2 endoporus and copper pipe 1, aluminum pipe 3 external diameter nominal size are identical, and sleeve pipe 2 is sleeved on the copper and aluminium welding Tube to tube fittings, sleeve pipe 2 with scribble coating 4 between the copper and aluminium welding Tube to tube fittings matches.Sleeve pipe 2 usefulness engineering plastics or metallic material are made, and present embodiment middle sleeve 2 usefulness PVC engineering plastics are made.Coating 4 is a kind of liquid high-strength structural adhesives that are used for binding metal material, plastics, and concrete application fourth is fine in the present embodiment---phenol aldehyde adhesive.With the sleeve pipe 2 of coating 4 bonding suits, increased the long-pending and resistance to flexure of lateral cross section of this section effectively on the copper and aluminium welding Tube to tube fittings outer wall.This copper and aluminium welding Tube to tube fittings with outer protection unit is difficult for being reduced the possibility that the domestic air conditioner connecting pipe leaks greatly by crooked and damage without reason.
Another embodiment's of the utility model structure is identical with above-mentioned example structure, only is sleeve pipe 2 usefulness copper metallic material manufacturings, uses metallic material to make the resistance to flexure that sleeve pipe 2 can significantly improve the copper and aluminium welding Tube to tube fittings.This copper and aluminium welding Tube to tube fittings with outer protection unit is difficult for being reduced the possibility that the domestic air conditioner connecting pipe leaks greatly by crooked and damage without reason.Further improve as the utility model, sleeve pipe 2 covers made from metallic material install on the copper and aluminium welding Tube to tube fittings outer wall and with after coating 4 bondings, can carry out spinning to sleeve pipe 2, with the quality of connection of further raising sleeve pipe 2 with the copper and aluminium welding Tube to tube fittings.
