Abstract

A double protection anticorrosion apparatus comprises an auxiliary electrode and a sacrificial anode and is characterized in that: the sacrificial anode is connected with a relay; the other end of the relay is connected with a control power supply, and the output end of the control power supply is connected with the auxiliary electrode. The utility model absorbs the advantages of existing similar apparatus and also has the advantages of current protection and sacrificial anode protection; meanwhile, the apparatus can realize automatic switching to keep storage water heater under ideal cathodic protection whether the power supply is switched on or off, thereby greatly prolonging service life of water heater.

Description

Two guarantor's erosion protection systems
Technical field
The utility model relates to a kind of preventing metal corrosion device, particularly relates to a kind of pair of guarantor's erosion protection system.
Technical background
At present, in order to prevent corrosion, water-storage electric heater, solar water heater etc. adopt the cathodic protector of sacrificial anode (using the magnesium rod) or impressed current usually, but these two kinds of devices respectively have relative merits.With the protection of magnesium rod, though simple and reliable, the life-span is too short; Though long with the impressed current cathodic protection life-span, can not play a protective role when powered-down or outage.
Summary of the invention
The novel purpose of this reality provides a kind of pair of guarantor's erosion protection system, and it can overcome the above-mentioned shortcoming of prior art.
A kind of pair of guarantor's erosion protection system has a supporting electrode and a sacrificial anode, it is characterized in that this sacrificial anode connects a rly., and the other end of this rly. connects the control power supply, and the latter's output terminal is connected with supporting electrode.
The utility model has been drawn the existing outer advantage that is added with current protection and sacrificial protection; and can automatically switch; no matter storage water heater's container is being had under the power free situation, can both be among the good galvanic protection, prolonged water-heater work-ing life greatly.
Description of drawings and embodiment
Accompanying drawing is a structural representation of the present utility model.
This pair of guarantor's erosion protection system has supporting electrode 2 and sacrificial anode magnesium rod 4, it is characterized in that sacrificial anode 4 connects a rly. 5, and the other end of this rly. 5 connects control power supply 1, and the latter's output terminal is connected with supporting electrode 2.Present embodiment is example with the water-heater, as shown in drawings: magnesium rod 4 and supplementary anode 2 insulating mounting in the water-heater container is protected body 3, are connected an end of rly. 5 on the protected body 3.An output terminal of power-supply controller of electric 1 is connected on the protected body 3 of water-heater.After connecting power supply, supporting electrode 2 forms electrolyzer with protected body 3; When electricity was arranged, magnesium rod 4 disconnected with protected body 3 under the effect of rly. 5, can be connected with control power supply 1, as the reference electrode of constant potential impressed current protection; During no impressed current, magnesium rod 4 disconnects with control power supply 1, is electrically connected with protective 3, and at this moment the excellent 4 pairs of protectives 3 of magnesium play the provide protection of sacrificial anode.

Claims (1)

1, a kind of pair of guarantor's erosion protection system, one supporting electrode (2) and a sacrificial anode (4) are arranged, it is characterized in that this sacrificial anode (4) connects a rly. (5), the other end of this rly. (5) connects control power supply (1), and the latter's output terminal is connected with supporting electrode (2).
