Abstract
The invention belongs to the field of air conditioner fittings, particularly relates to a metal tube of an improved metal splitter. The metal tube comprises a metal tube body, wherein the metal tube body comprises a central section and necking sections positioned at the two sides of the central section; the central section and the necking sections are integrally formed; the diameters of the necking sections, extending towards the two sides, of the central section are sequentially reduced; and a difference value between the outer diameter and the inner diameter of the central section is equal to that between the outer diameters and the inner diameters of the necking sections. According to the invention, the practicability and the strength of the metal tube of the metal splitter are improved.
Description
Technical field
The invention belongs to air conditioner parts field, be specifically related to the metal tube of the metal splitter after a kind of improvement.
Technical field
The invention belongs to air conditioner parts field, be specifically related to the metal tube of the metal splitter after a kind of improvement.
Background technique
After the metal tube necking of prior art, along with the extension of central segment is extended, the wall thickness of reducing section is also thereupon thinning, and so the intensity of this metal tube reducing section when mounted can reduce.At present, market occurs connecting part's examination that a kind of metal tubes is exempted to weld, it requires very high to metal tube inside/outside diameter size, if can meet its requirement, the metal tubes quality connected out reaches and exceedes current traditional flame welding.
Current most of metal tube necking all adopts hydraulic pressure reducing, pneumatic reducing and lathe ball hobboing cutter drawing reducing, and this several reducing above-mentioned can only ensure external diameter or internal diameter size, does not ensure size after multiple tracks internal diameter external diameter and the reducing of wall thickness reducing.
For solving the problems of the technologies described above, the applicant provides the metal tube of the metal splitter after a kind of improvement, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of metal tube of metal splitter, ensure the wall thickness of reducing section, to improve practicability and the intensity of the metal tube of metal splitter.
For achieving the above object, the concrete disclosed technological scheme of the present invention is: a kind of metal tube of metal splitter, comprise metal tube body, metal tube body comprises central segment and is positioned at the reducing section of central segment both sides, described central segment and reducing section are formed in one, the reducing section diameter that described central segment extends to two side directions successively decreases successively, and the external diameter of described central segment and the difference of internal diameter equal the external diameter of reducing section and the difference of internal diameter.
Beneficial effect of the present invention: the present invention equals the external diameter of reducing section and the difference of internal diameter by the external diameter of central segment and the difference of internal diameter, makes the wall thickness of reducing section and the wall thickness of central segment, improves join strength and the practicability of metal tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is using state figure of the present invention.
Embodiment
As shown in Figure 1, 2, what the present invention disclosed is a kind of metal tube of metal splitter, comprise metal tube body 1, metal tube body 1 comprises central segment 11 and is positioned at the reducing section 12 of central segment 11 both sides, described central segment 11 and reducing section 12 are formed in one, reducing section 12 diameter that described central segment 11 extends to two side directions successively decreases successively, and the described external diameter of central segment 11 and the difference of internal diameter equal the external diameter of reducing section and the difference of internal diameter.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present invention.
Claims (1)
1. the metal tube of a metal splitter, comprise metal tube body, metal tube body comprises central segment and is positioned at the reducing section of central segment both sides, described central segment and reducing section are formed in one, it is characterized in that: the reducing section diameter that described central segment extends to two side directions successively decreases successively, and the external diameter of described central segment and the difference of internal diameter equal the external diameter of reducing section and the difference of internal diameter.
