<p>The present invention relates to a fire-fighting water keeping device for a stainless steel water tank. A lower end of the water tank installed on the ground or under the ground is provided with a fire-fighting pipe, and a water supply pipe is installed to an upper portion of the fire-fighting pipe, so that the water is always left in the water tank which is positioned below the water supply pipe to adjust the level of the water, thereby using the water as the fire-fighting water in time of emergency such as fire. The bottom surface of the water tank is connected to the lower portion of the fire-fighting pipe via the water supply pipe, thereby preventing pollution of the bottom of the water tank and thus using the water reliably. Since the water stored in the water tank is continuously circulated, the water is maintained in an unfrozen state in winter, thereby improving the reliability of the product.</p> |
