Abstract:
PROBLEM TO BE SOLVED: To provide a tank-draining device capable of easily performing the recovery of discharged water, and hardly generating the leak of the discharged water on its recovery and splashing the discharged water on a worker.
SOLUTION: This tank-draining device is provided by ejecting water along a slope of a conical part installed as projecting 27c and a packing 29 so as to spread from a draining port 3, reflecting the water with an inner wall of a large diameter part 21b of a cylindrical holder 21 and discharging the water to the outside while further gathering it to the center of the device along an inner wall of a ring 33. In this case, since there is an angle in the flow of the water, the water flows smoothly. Therefore, an inner pressure at an opening 31 is low and leak from the upper part of a screw 4 hardly occur.
