Model utility content
In order to overcome the electrochemical corrosion produced between ambrose alloy ring sleeving steel flange, the utility model provides a kind of for ambrose alloy ring sleeving steel flange electrical insulation protecting jacket.Ambrose alloy ring can be overlapped steel flange with pine and carry out electrical insulation isolation by this electrical insulation protecting jacket, plays the effect stoping electrochemical corrosion, does not also affect the using function of flange simultaneously.
To achieve these goals, the utility model adopts following technological scheme:
For an electrical insulation protecting jacket for ambrose alloy ring sleeving steel flange, this protecting jacket comprises cylindrical shell and flanging, and described flanging is outwards bent by cylindrical shell one end and forms, described cylindrical shell and flanging one-body molded.
Preferably, described cylindrical shell is hollow cylinder, and described flanging is circular, square or regular polygon.
Preferably, the bending place between cylindrical shell and flanging is rounding.
Preferably, described protecting jacket is corrosion resistant isolation material protecting jacket.
Preferred, described protecting jacket is nylon protecting jacket or teflon protecting jacket.
Preferably, described protecting jacket is between pine cover steel flange and ambrose alloy ring, and barrel jacket is outside ambrose alloy ring.Namely pine is overlapped steel flange and ambrose alloy ring is isolated at radial direction electrical insulation by cylindrical shell, and pine is overlapped steel flange to flanging and ambrose alloy ring is isolated at axial direction electrical insulation.
Preferred, the length of cylindrical shell is more than or equal to the thickness of pine cover steel flange, and the thickness of cylindrical shell is slightly less than the radial distance between pine cover steel flange and ambrose alloy ring, and cylinder internal diameter is slightly larger than the external diameter of ambrose alloy ring.
Preferred further, cylinder internal diameter 0.3mm larger than the external diameter of ambrose alloy ring.
Preferably, the width of described flanging equals the width of ambrose alloy ring, and the thickness of flanging equals the axial distance between pine cover steel flange and ambrose alloy ring.
Preferred, the thickness of flanging is not less than 1mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model be used for the cylindrical shell of electrical insulation protecting jacket of ambrose alloy ring sleeving steel flange and flanging one-body molded, structure is simple, is easy to manufacture; Between ambrose alloy ring and pine cover steel flange, use this protecting jacket not affect the linkage function of flange; can also simultaneously at radial and axial isolated pine cover steel flange and ambrose alloy ring; avoid producing electrochemical corrosion therebetween, extend the working life of ambrose alloy ring sleeving steel flange under briny environment.

Embodiment
In order to better understand the utility model, below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, the electrical insulation protecting jacket for ambrose alloy ring sleeving steel flange have employed flanging design, and comprise cylindrical shell 5 and flanging 6, flanging 6 is outwards bent by cylindrical shell 5 one end and forms.Preferably, the bending part between cylindrical shell 5 and flanging 6 is called bending place, and bending place adopts rounding design, and protecting jacket 1 and ambrose alloy ring 2 can be made like this to fit completely.Preferably, described rounding have employed the fillet design of R5, and namely fillet radius is 5mm.
As shown in Figure 2, when adopting ambrose alloy ring sleeving steel Flange joint ambrose alloy pipe 4, ambrose alloy ring 2 welds with ambrose alloy pipe 4, and ambrose alloy ring 2 and pine cover steel flange 3 play connection function jointly.When using the utility model to be used for the electrical insulation protecting jacket of ambrose alloy ring sleeving steel flange; protecting jacket 1 is enclosed within outside ambrose alloy ring 2; protecting jacket 1 is between pine cover steel flange 3 and ambrose alloy ring 2; pine is overlapped steel flange 3 by cylindrical shell 5 to be isolated at radial direction electrical insulation with ambrose alloy ring 2, and pine is overlapped steel flange 3 by flanging 6 to be isolated at axial direction electrical insulation with ambrose alloy ring 2.Pine cover steel flange 3 does not have point of contact with ambrose alloy ring 2, described can electrical insulation isolation.Isolated by electrical insulation, avoid pine cover steel flange 3 in wet environment to produce electrochemical corrosion, even if be immersed in briny environment, also effectively can reduce the rate of corrosion of pine cover steel flange 3.Therefore, when by when adopting the pipeline after this Flange joint to be placed in briny environment, just as pine overlapped steel flange 3 and ambrose alloy pipe 4 is placed in briny environment separately, can not because of they one for steel one is for copper and produce electrochemical corrosion.In order to reach better anticorrosion ability, in the present embodiment, protecting jacket 1 adopts nylon-11 to make.
In the present embodiment, cylindrical shell 5 is hollow cylinder, and flanging 6 is circular, square or regular polygon.The length A of cylindrical shell 5 is more than or equal to the thickness of pine cover steel flange 3, the thickness B of cylindrical shell 5 is slightly less than the distance between pine cover steel flange and ambrose alloy ring, be 1mm in the present embodiment, the internal diameter E of cylindrical shell 5 slightly larger than the external diameter of ambrose alloy ring 2, the internal diameter E of cylindrical shell 5 0.3mm larger than the external diameter of ambrose alloy ring 2 in the present embodiment.The width C of described flanging 6 equals the width of ambrose alloy ring 2, and the thickness D of flanging 6 equals the distance between pine cover steel flange and ambrose alloy ring, and described thickness D is not less than 1mm, and the thickness D of flanging 6 is 2mm in the present embodiment.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple changes can also be made, all should be considered as belonging to protection scope of the present invention.
