Abstract
The invention belongs to materials processing technology field, more particularly to the connection method of a kind of water storage type liner of water heater and sacrificial magnesium alloy anode.The connection method uses inside and outside double layer nut structure, magnesium stick iron core (5) to be welded on interior nut (3) top center hole, connect with interior nut (3) by screw thread (4 3)；Interior nut (3) is connect by screw thread (4 2) with exterior nut cap (2), and exterior nut cap (2) is fixed on by screw thread (4 1) on water heater liner；Interior nut (3) is closed in exterior nut cap (2) inner cavity with solder joint (1), to prevent to cause water heater to drip due to weld defect or weld corrosion, leak the phenomenon that, efficiently solve traditional magnesium anode stick coupling nut and the easy seepage problem of iron core weld seam.
Description
Technical field
The invention belongs to materials processing technology field, more particularly to a kind of water storage type liner of water heater and sacrificial magnesium alloy
The connection method of anode.
Background technology
In fresh water environment, the electrode potential of magnesium alloy anode is relatively negative, is widely used in storage-type electric water heater (including electric heating
Hydrophone) liner protection in.During electric heater accumulates over a long period use, such as without corrosion protection, water heater liner meeting
Burn into perforation occurs, leads to leak, electric leakage accident, seriously threatens the personal safety of user.Therefore, it carries out in electric heater
The Anti-corrosion design of courage can effectively improve electric heater service life.
In order to play the role of fixed and conducting, sacrificial magnesium alloy anode stick center is through a diameter of 2~3mm's or so
Iron wire.Traditional sacrificial magnesium alloy anode stick is fixed on using steel nut on storage-type electric water heater liner, and is realized by nut
The conducting of anode stub and water heater liner conveys electronics to steel inner container, becomes cathode and protected.Steel nut top
There are one portion centersLeft and right aperture, for magnesium stick iron core to be welded on steel cap, when due to welding, nut and magnesium stick
Gap gas is expanded rapidly by heating, is excessive, causes to be formed inside solder joint and closes loose or penetrating aperture, as magnesium stick is gradual
Corrosion dissolution, these weld defects generate dripping phenomenon, easily lead to electric leakage accident under the effect of water heater liner hydraulic pressure.
Invention content
The purpose of the present invention is to provide the connection method of a kind of water storage type liner of water heater and sacrificial magnesium alloy anode,
Specific technical solution is as follows：
A kind of connection method of water storage type liner of water heater and sacrificial magnesium alloy anode, using inside and outside double layer nut knot
Structure, magnesium stick iron core 5 are welded on 3 top center hole of interior nut, are connect with interior nut 3 by screw thread 4-3；Interior nut 3 passes through spiral shell
Line 4-2 is connect with exterior nut cap 2, and exterior nut cap 2 is fixed on by screw thread 4-1 on water heater liner；Interior nut 3 is closed with solder joint 1
In 2 inner cavity of exterior nut cap, solve the problems, such as to cause water heater to drip, leak due to weld defect or weld corrosion.
When 6 diameter 25.98mm, long 350mm of magnesium stick, 3 internal diameter of interior nut isOuter diameter isIt is a length of3 top center bore dia of interior nut isInterior nut is
Cylindrical steel cap carries internal and external screw thread；
2 internal diameter of exterior nut capOuter diameterIt is longIt is high in nutExterior nut cap is hexagonal (hexagon)nut, has internal and external screw thread.
Beneficial effects of the present invention are：Connection method using the present invention can be solved effectively due to weld defect or weldering
Seam corrosion and cause water heater to drip, leak the problem of, and then extend electric heater service life.
