Abstract
The invention discloses a copper pipe. The copper pipe comprises a copper pipe body. A fluid flow passage is arranged inside the copper pipe body. The external diameter of the copper pipe body is gradually reduced, therefore, the structure strength of the copper pipe can be strengthened, meanwhile, the internal diameter of the fluid flow passage is gradually reduced, the fluid flow passage corresponds to the copper pipe body, and the thickness of the copper pipe body can be kept all the time. The copper pipe body cannot be broken easily while the structure strength of the copper pipe is increased. The copper pipe is simple in structure, convenient to machine and form and high in strength.
Description
Technical field
The present invention relates to a kind of improvement of copper pipe, refer in particular to a kind of simple in structure, facilitate machine shaping, and the good copper pipe of intensity.
Background technique
In prior art, the external diameter of copper pipe is consistent at length direction, and the internal diameter of the fluid passage in copper pipe is also consistent, while adopting the drawing moulding, when the size of the long copper pipe of length of copper pipe is large, be difficult to keep quality of product, and the intensity of produced product is not good, easily deforms; For this reason, we researched and developed a kind of simple in structure, facilitate machine shaping, and the good copper pipe of intensity.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of simple in structure, facilitate machine shaping, and the good copper pipe of intensity.
For achieving the above object, the technical solution used in the present invention is: a kind of copper pipe comprises the copper pipe body; Be provided with fluid passage in described copper pipe body; The external diameter of described copper pipe body reduces gradually.
Preferably, the tapering of described copper pipe body is less than 0.1.
Preferably, the internal diameter of described fluid passage reduces gradually, and corresponding with the copper pipe body.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The external diameter of the copper pipe body of copper pipe of the present invention reduces gradually, thereby can strengthen the structural strength of copper pipe, simultaneously, the internal diameter of described fluid passage reduces gradually, and corresponding with the copper pipe body, can make like this thickness of copper pipe body remain unchanged always, in the structural strength that strengthens copper pipe, also can make not frangibility of copper pipe body; The present invention is simple in structure, facilitate machine shaping, and intensity is good.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The sectional view that accompanying drawing 1 is copper pipe of the present invention;
Wherein: 1, copper pipe body; 2, fluid passage.
embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is a kind of copper pipe of the present invention, comprises copper pipe body 1; Be provided with fluid passage 2 in described copper pipe body 1; The external diameter of described copper pipe body 1 reduces gradually; The internal diameter of described fluid passage 2 reduces gradually, and corresponding with copper pipe body 1; The tapering of described copper pipe body 1 is less than 0.1, is unlikely to too large in order to the internal diameter of fluid passage 2 is reduced, and affects the ability that fluid passes through.
The external diameter of the copper pipe body of copper pipe of the present invention reduces gradually, thereby can strengthen the structural strength of copper pipe, simultaneously, the internal diameter of described fluid passage reduces gradually, and corresponding with the copper pipe body, can make like this thickness of copper pipe body remain unchanged always, in the structural strength that strengthens copper pipe, also can make not frangibility of copper pipe body; The present invention is simple in structure, facilitate machine shaping, and intensity is good.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
