A steel cap provided with a central hole is arranged at the upper end of the steel core. The resistor is located in the central hole. One end of the resistor is connected with the steel core through a guide wire, and the other end of the resistor is connected with the steel cap through a guide wire. Insulated sealing rubber is filled in the central hole. The sealed built-in resistance magnesium anode can prevent the resistor from losing efficacy due to water seepage, and can prevent the resistor from falling off.
Description
Technical field
The utility model relates to the magnesium anode aseptic technic, relates in particular to the resistance built-in magnesium anode with sealing property.
Background technology
Magnesium and magnesium alloy are used widely at electronics, automobile and aerospace industry owing to having good performance, become substitution of Al alloy, iron and steel and engineering plastics to realize light-weighted ideal material.
But the shortcoming of magnesium and its alloys is corrosion-resistant, in the short period of time can be because corrosion cause part failure in some environment, and this has limited its use range greatly.Corrosion becomes one of greatest problem of the present magnesium alloy large-scale application of impact.
At present; the aseptic technic of magnesium and magnesium alloy is to utilize its electronegativity in medium; according to electrochemical principle; provide cathodic current by ionogen such as soil, water to protected body (such as utensil of steel structure etc.) from the magnesium anode material bodies; make protected utensil carry out negative electrode; along with constantly flowing of electric current, anode material constantly consumes, and realizes galvanic protection.Yet take water etc. as medium and after magnesium anode consisted of galvanic cell, driving voltage was very large, generation current is relatively also very large at protected body.The magnesium anode dissolution rate is inevitable also fast, does not reach the purpose of long period keeping device.
In order to reduce the dissolution rate of magnesium anode, usually increase a resistance between magnesium sacrificial anode and protected body, reduce driving voltage, thereby reduce the magnitude of current of magnesium anode, this a kind of way that simply should go of can yet be regarded as.
Yet although the resistance magnesium anode of producing at present plays the effect of sharing voltage and steady current, long-time use meeting loses effect because infiltration causes resistance, and because steel core and being connected not firmly of resistance easily come off.
The utility model content
The utility model be intended to solve in existing resistance magnesium anode resistance easily immersion and with the solid technical problem of magnesium rod not prison welding.
To achieve these goals, the utility model provides a kind of built-in resistor magnesium anode of sealing, this magnesium anode comprises magnesium rod and resistance, this magnesium rod is built-in with steel core, the upper end of this steel core is provided with the steel cap with centre hole, and this resistance is arranged in this centre hole, and an end of this resistance is connected with steel core, the other end of this resistance is connected with this steel cap, is filled with electric insulating sealant in this centre hole.
According to built-in resistor magnesium anode of the present utility model, be provided with the upper end that is positioned at this insulator cap with the insulator cap of centre hole and metallic gasket and this steel cap in the upper end of this steel core, this steel core passes this insulator cap and metallic gasket is connected and fixed, and an end of this resistance is connected with this metallic gasket.
According to built-in resistor magnesium anode of the present utility model, be provided with nut in the upper end of this steel cap.
Built-in resistor magnesium anode of the present utility model, by electric insulating sealant, resistance wrapped up fully and be connected with resistance with metallic gasket, metallic gasket by steel core, having solved in existing resistance built-in magnesium anode that resistance easily is flooded and the discharge of magnesium rod consumes the caducous technical problem of steel core in latter stage.
Description of drawings
Fig. 1 is that illustration is according to the cross-sectional view of the structure of built-in resistor magnesium anode of the present utility model.
Embodiment
Now, describe exemplary embodiment of the present utility model in detail with reference to accompanying drawing.Unless should be pointed out that in addition to illustrate, relative configuration, numeral and the numerical value of the parts of describing in these embodiments do not limit scope of the present utility model.
Fig. 1 is that illustration is according to the cross-sectional view of the structure of built-in resistor magnesium anode of the present utility model.As shown in Figure 1, built-in resistor magnesium anode of the present utility model comprises magnesium rod 4, and this magnesium rod 4 can be to be made by high purity magnesium or magnesium alloy (such as AZ31 magnesium alloy or M1C magnesium alloy etc.).Be provided with steel core 5 in magnesium rod 4.Be provided with the insulator cap with insulator cap 3(such as plastics or the resin etc. of centre hole in the upper end of steel core 5) and metallic gasket 6, steel core 5 passes insulator cap cap 3 and metallic gasket 6 is rear and metallic gasket 6 is connected and fixed.One end of resistance 8 is connected with metallic gasket 6 by wire.
In addition, although in superincumbent description, be provided with in the upper end of steel core 5 that insulator cap 3 is connected with metallic gasket and an end of resistance 8 is connected with steel core 5 by metallic gasket 6, yet the utility model is not limited to this, also can not use insulator cap 3 and metallic gasket 6, and make an end of resistance 8 directly be connected with steel core 5.
In preferred version of the present utility model, as shown in Figure 1, can nut 1 be set in steel cap 7 upper ends, with the protection of further reinforcement to resistance.
in built-in resistor magnesium anode of the present utility model, in the steel core upper end, insulator cap is housed, metallic gasket is equipped with in the insulator cap upper end, its important part is that insulator cap and metallic gasket are provided with centre hole, steel core passes centre hole and metallic gasket is connected and fixed, again with the wire of resistance one end and welded metal pad together, put again the internal layer steel cap with centre hole on insulator cap, make between internal layer steel cap and insulator cap and leave sufficient space, again the other end wire of resistance being passed internal layer steel cap centre hole is welded on the steel cap, resistance is just stayed in the interior cloth space of insulator cap and internal layer steel cap combination like this.Again electric insulating sealant is injected in the centre hole of internal layer steel cap resistance is wrapped up fully, nut is fitted snugly on internal layer steel cap at last.So in fact, steel core, resistance, nut are effectively linked together.
According to above-mentioned built-in resistor magnesium anode of the present utility model, by electric insulating sealant, resistance is wrapped up fully, prevented that resistance from easily being soaked into by media such as water, and caused resistance to lose efficacy.
In addition, in above-mentioned built-in resistor magnesium anode of the present utility model, by metallic gasket is set, and steel core is connected with resistance with metallic gasket, metallic gasket, has prevented from consuming the easy obscission of steel core in latter stage in the discharge of magnesium rod.
So with reference to exemplary embodiment, the utility model is illustrated, but should be appreciated that the utility model is not limited to disclosed exemplary embodiment.Should give the widest explanation to the scope of claims, so that it contains all modification, equivalent structure and function.
