Description
Technical field
The present invention relates to technical field of water heaters more particularly to a kind of electron anodes, and use the storage of the electron anode
Water installations and water heater.
Background technology
Tank parts need for a long time as water storage device important in water-heater system under the hot environment for generating hot water
Work is contacted with water, therefore, the anti-corrosion capability of inner water tank is the important indicator judged water heater product quality.Water at present
There are mainly two types of modes for the anticorrosive measure of case liner：One is sacrificial protection, is encapsulated with water heater sewage draining exit screw plug
Magnesium stick protects liner in being used as sacrificial anode in water heater by preferentially sacrificing magnesium stick, due to preferential using magnesium metal stick
While corrosion, it will also result in a large amount of magnesium ion ionization to water tank, the shape of incrustation scale (calcium carbonate, magnesium carbonate) can be accelerated in this way
At general just to need to replace magnesium stick by the 2-3 years；The second is cathode constant potential Protection Code, by being arranged in water heater

Once considered the electron anode of design drawing 1.It is the schematic diagram of electron anode as shown in Figure 1, Fig. 2 shows the electronics of Fig. 1
The schematic diagram of anode interconnecting piece.As depicted in figs. 1 and 2, one end (right end shown in Fig. 2 (a)) of interconnecting piece uses external screw thread knot
Structure is directly connected to the internal thread structure on water tank, for ease of the portion of being clamped and connected to be fixedly connected with external (such as water tank), such as Fig. 1
(b) shown in, the other end outer surface of interconnecting piece is set as hexagon, forms the structure similar to hex nut.But use spiral shell
Line connection can be because lead to the damage of screw thread, failure, and since material is made of nylon, with water in assembly and disassembly process
Case screw thread is directly connected to the fracture for being also likely to that connection structure can be caused, a little outer because moulding is different with metalwork attribute
Power or other factors can all cause this consequence, to be changed without electron anode.In addition, interconnecting piece uses class hexagonal spiral shell
Female structure is connect with external stability, is also resulted in and is sealed such problem such as loosely.
It is urgent to provide a kind of electron anodes as a result, and using the water storage device and water heater of the electron anode, to solve
Existing electronics sun grade is threadedly coupled the fragile failure of water storage device, and sealing loosely the shortcomings of.
