Document Type and Number:
Japanese Patent JP7253687
Kind Code:
B2
Abstract:
To provide a drainage system, which discharges redundant water without using overflow piping to maintain the water level in a tank to be constant while storing water, and is able to arbitrarily set the water level of storage and that for starting discharge.SOLUTION: A valve member 5, which opens and closes a drain port 2 of a washbowl B that is a tank, comprises: a pressure valve 7 which opens to discharge redundant water to the sewage side when the pressure from the inside of the washbowl B exceeds a designated pressure; and a pressure adjustment mechanism 40 which arbitrarily adjusts the pressure for the pressure valve 7 to open at. A pressure valve body 15 is actuated by the magnetic force acting in the direction of attraction between a magnet 17 and a magnet 18. The pressure adjustment mechanism 40 consists of a male screw part 41 and a female screw part 42, and changes the distance between the magnets to adjust the magnet force to enable setting the level of storable water as required according to desired levels that vary depending on the tank, usage, and users.SELECTED DRAWING: Figure 4
