Description
Technical field
The utility model belongs to storage water heater's protection device field, more particularly to a kind of storage water heater's inner bag electronics
Anode.
Background technology
Storage water heater's inner bag is immersed in water environment due to long-time, is easily produced corrosion failure, is caused inner bag and heat
Hydrophone is scrapped, and the principle frequently with cathodic protection carries out anti-corrosion protection to inner bag, and wherein impressed current cathodic protection is to be applied to
One of important method of storage-type electric water heater inner bag protection, its general principle is by by the negative of protection inner bag and external dc power supply
Extremely it is connected, additional power source positive pole is then connected with electron anode (impressed current anode), forces electronics flow direction by protection inner bag, so that by
Protection inner bag current potential is protected less than surrounding environment.
Electron anode (impressed current anode) is one of part of impressed current cathodic protection method most critical, and its service life will foot
Enough long, i.e., the consumption rate of electron anode material is low as far as possible.The most frequently used electron anode material of current storage water heater's inner bag
Expect the titanium alloy for face coat, be shaped as elongated silk or tubulose.The coated on titanium alloy of silk or tubulose is due to machinability
Difference or cost are high, tend not to be arranged on be directly connected on inner bag with positive source wire, it is necessary to by with other metal materials
Part connection after be connected again with positive source wire.
Because electron anode is connected with external dc power supply positive pole, protection electronics, electronics are provided for inner bag during protection
The junction dissolving speed of certain dissolving, particularly titanium alloy and other metal materials can occur for the part that anode is contacted with solution
Faster, and coated on titanium alloy dissolution velocity is low, good corrosion resistance for degree, with longer service life, meets use requirement, but with
If the selection of other part materials or design unreasonable that coated on titanium alloy connects, it may occur that the fast phenomenon of dissolution velocity, make electricity
Sub- anode is integrally ineffective, causes the failure of whole impressed current cathodic protection, make inner bag lose corrosion protection there may be
Serious consequence.
Utility model content
The purpose of this utility model is the part contacted for existing electron anode with solution, particularly wire electrode and other
The junction dissolution velocity of metal material is not enough faster, proposes a kind of storage water heater's inner bag electron anode, and its feature exists
In the electron anode is by corrosion resistant wire electrode, the screw mandrel of connection DC power anode wire and screw mandrel and wire electrode junction
The insulator composition of parcel；Wherein, wire electrode and screw mandrel are using welding or threaded connection, and in the two joint, injection parcel is formed
Insulator.
The wire electrode is the corrosion-resistant conductive material of titanium alloy, graphite, corrosion-resisting steel or high-silicon cast iron.
The screw mandrel material is conductive metal material, such as conventional carbon steel Q235.
The insulator is that the screw mandrel after connection and wire electrode are carried out into sealed insulation parcel, electron anode there was only electrode
Silk and insulator can be contacted with solution, and screw mandrel does not contact solution.
The insulator material is a kind of or ceramic material in plastics PBT, PC, PA, MPPO.
Described insulator one end is polygon, and side number is more than 3, such as quadrangle or hexagon, it is ensured that electron anode
Fixation is not rotated during assembly or disassembly.
The beneficial effects of the utility model are by using resistant material in screw mandrel and wire electrode and increasing in junction
Insulator carries out insulation parcel, it is possible to prevente effectively from electron anode other conductive material and solution contacts in addition to wire electrode, it is to avoid
Quick dissolving occurs for other metal positions particularly wire electrode and screw mandrel junction of the electron anode in addition to wire electrode, it is ensured that electricity
The long-life of sub- anode.
