であるエンジンを守るために不可欠のものである。(Effect of the invention) As can be seen from the above, the present invention can be used for a long period of time (approximately 5
In addition to preventing galvanic corrosion over the course of several years, it is also easy to replenish zinc because it is not tightened with bolts, making it essential for protecting the engine, which is life at sea.
さらに本発明によると、冷却水タンク内の錆は約１ケ月

けている。In FIG. 1, an electrolytic corrosion prevention device 6x according to the present invention includes an electrolytic corrosion prevention container 2, a cooling water inflow hole 3 and an outflow hole 3' at both ends thereof.
In addition, the inside of the electrolytic corrosion prevention container 2 is made hollow, and a low potential metal body 4 such as zinc is placed inside, so that cooling water can pass through the inside of the container. A passage 4a is provided.

なけて使用するものである。An example of the use of this more efficient galvanic corrosion protector 1 is shown in FIG. Cooling water is taken in from Kingston 5, and if bending is required, use a bending joint 6 to connect the electrolytic corrosion protector 1.
Cooling water flows into the engine, flows out of the cooling water tank, enters a cooling tank 8, cools the engine, and then exits through an exhaust pipe 9. In this way, this electrolytic corrosion preventer l is installed at the intermediate position between the king store 5 and the bongtsu, and this galvanic corrosion preventer l is installed between the bongtsu, the cooling tank 8,
It is used by electrically connecting the clutch wire 10 with the wiring 1M11.

って行き、通路４ａの孔を塞ぐことがなく安全である。By doing this, the low potential metal such as zinc in the electrolytic corrosion preventer 51 flows out due to the JfA process of plating, and a plating layer is formed inside each component. In addition, since the cut 1j4b is formed on the upper part of the low potential metal body (zinc) in the turning direction, this low potential metal body is etched through the internal cut 4b by electrolytic erosion as shown in Fig. 3(a). As shown in (d), the upper part decreases quickly, and the hole in the passage 4a is not blocked, so it is safe.
