Abstract
The invention discloses an anti-corrosion pipeline which comprises a pipeline body and an anti-corrosion layer. A fluid channel is formed inside the pipeline body. Grooves are evenly formed in the inner wall of the fluid channel. The anti-corrosion layer is arranged on the inner wall of the fluid channel and inserted into the grooves. The grooves are spirally formed. Opening portions of the grooves are smaller than the bottoms of the grooves. The anti-corrosion pipeline is simple in structure, and the anti-corrosion layer is not easily disengaged.
Description
Technical field
The present invention relates to a kind of improvement of anti-corrosion pipeline, refer in particular to a kind of simple in structure, the anti-corrosion pipeline of anti-corrosion layer difficult drop-off.
Background technique
In prior art, while carrying the more intense solution of corrosivity, the pipeline that usually adopts the reasonable steel of corrosion resistance of non-traditional machining to make, as 301 stainless steels, the cost of this steel is high, thereby the user cost of this pipeline is high; People were in order to reduce the cost of pipeline afterwards, on the inwall of the runner passage of pipeline, were provided with one deck corrosion-resistant coating; Pipeline body adopts more cheap metal to make, as iron; But the easy integral body of ducted corrosion-resistant coating of this structure comes off, and for this reason, we have researched and developed a kind of simple in structure, the anti-corrosion pipeline of anti-corrosion layer difficult drop-off.
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, the anti-corrosion pipeline of anti-corrosion layer difficult drop-off.
For achieving the above object, the technical solution used in the present invention is: a kind of anti-corrosion pipeline comprises pipeline body, anti-corrosion layer; Be provided with fluid passage in described pipeline body; The inwall of described fluid passage is provided with groove equably; Described anti-corrosion layer is arranged on the inwall of fluid passage, and inserts in groove.
Preferably, the linearly setting of described groove.
Preferably, described groove arranges in the shape of a spiral.
Preferably, the opening portion of described groove is less than the bottom of groove.
Preferably, described anti-corrosion layer is made by fluoroplastic.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Anti-corrosion pipeline of the present invention; Be provided with equably groove on the inwall of the fluid passage in described pipeline body; Described anti-corrosion layer is arranged on the inwall of fluid passage, and in the insertion groove, thereby make anti-corrosion layer more firm, difficult drop-off, especially described groove is the shape of threads setting, because the center line of groove and fluid passage is not parallel, during use, anti-corrosion layer is difficult for the whole flow direction integral body with fluid and comes off; Further, the opening portion of described groove is less than the bottom of groove, can prevent anti-corrosion layer radially coming off along fluid passage; The present invention is simple in structure, the anti-corrosion layer difficult drop-off.
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 anti-corrosion pipeline of the present invention;
Wherein: 1, pipeline body; 2, fluid passage; 3, groove; 4, anti-corrosion layer.
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 anti-corrosion pipeline of the present invention, comprises pipeline body 1, anti-corrosion layer 4; Be provided with fluid passage 2 in described pipeline body 1; The inwall of described fluid passage 2 is provided with groove 3 equably; Described anti-corrosion layer 4 is arranged on the inwall of fluid passage 2, and inserts in groove 3; Linearly or the helical setting of described groove; Described anti-corrosion layer is made by fluoroplastic.
In order further to improve the stability of anti-corrosion layer 4, also the opening portion of described groove 3 can be less than to the bottom of groove.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Anti-corrosion pipeline of the present invention; Be provided with equably groove on the inwall of the fluid passage in described pipeline body; Described anti-corrosion layer is arranged on the inwall of fluid passage, and in the insertion groove, thereby make anti-corrosion layer more firm, difficult drop-off, especially described groove is the shape of threads setting, because the center line of groove and fluid passage is not parallel, during use, anti-corrosion layer is difficult for the whole flow direction integral body with fluid and comes off; Further, the opening portion of described groove is less than the bottom of groove, can prevent anti-corrosion layer radially coming off along fluid passage; The present invention is simple in structure, the anti-corrosion layer difficult drop-off.
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.
