Abstract
The utility model provides a temperature controlling anticorrosion device, comprising an auxiliary anode, characterized in that the signal collecting end of a power supply controller is connected with a thermosensitive device, and the output end of the power supply controller is connected with the auxiliary anode. The utility model has the advantages that the thermosensitive device can replace a reference electrode to be a signal collecting controller and a part that can feed back signals to the power supply controller. The structure is simple and the reliability is strong without a reference.
Description
Technical field
The utility model relates to a kind of preventing metal corrosion device, particularly relates to a kind of temperature control erosion protection system.Mainly be applicable to the storage water heater of material of the same race, as stainless steel inner container electricity, solar water heater.
Technical background
At present, the impressed current protection device is a kind of efficient apparatus that prevents metallic corrosion, and it normally adopts reference electrode and supplementary anode as a reference and function unit, and its shortcoming is often to cause whole device paralysis because reference electrode lost efficacy.
Summary of the invention
The purpose of this utility model provides a kind of temperature control erosion protection system, and it can overcome the above-mentioned shortcoming of prior art.
A kind of temperature control erosion protection system has a supplementary anode, it is characterized in that the signals collecting end of power-supply controller of electric connects a temperature-sensitive device, and its output terminal is connected with supplementary anode.
Advantage of the present utility model is to replace reference electrode as signals collecting with to the parts of power-supply controller of electric feedback signal with temperature-sensitive device.It is simple in structure, do not need reference electrode, good reliability.
Description of drawings and embodiment
Accompanying drawing is a structural representation of the present utility model.
This temperature control erosion protection system has a supplementary anode 2, it is characterized in that the signals collecting end of power-supply controller of electric 1 connects a temperature-sensitive device 3, and its output terminal is connected with supplementary anode 2.When using the utility model, be example, make temperature-sensitive device 3, supplementary anode 2 is placed in the housing 4, and power-supply controller of electric is connected with housing 4 with lead near this water-heater housing 4 with the electric water heater.Apply certain impressed current by power-supply controller of electric 1, make housing 4 cathodic polarizations.When water temperature was hanged down, the protective current that water-heater housing 4 needs was little, and outward current is little, and water-heater housing 4 is within the normal galvanic protection scope; When water temperature raise, the protective current that needs increased, and temperature-sensitive device 3 increases the outward current of power-supply controller of electric 1, and the current potential on the water-heater housing 4 still is within the required protection potential.
Claims (1)
1, a kind of temperature control erosion protection system has a supplementary anode (2), it is characterized in that the signals collecting end of power-supply controller of electric (1) connects a temperature-sensitive device (3), and its output terminal is connected with supplementary anode (2).
