CONSTITUTION:A sheetlike magnet 18 is stuck on a rim 17 of a shielding body 9, and in a normal service state, this shielding body 9 is attracted to the bottom of a perforated plate 7 or a projection at the lower part, and an upper opening of a perforated plate receiving frame 5 is made to come into a state of being closed. When water flows in the inner part or the upper part of the shielding body 9 and it has exceeded a constant water level, the shielding body 9 is separated from the perforated plate 7 and dropped by water weight, whereby it is engaged with a shielding body receiver 14. In this state, the upper opening if the perforated plate receiving frame 5 is opened and interconnected to drain ports 12, 12a, thus collected water is made to flow out of these ports. With this constitution, at usual time, air pressure in a computer room is maintained as it is, so that any inundation into a computer is preventable at time of emergency when a leakage of water out of a cooling machine of this computer has occurred.

Description

[Detailed Description of the Invention] [Object of the Invention] 1. Kurigami Nagibu■ The present invention provides a water-cooled system for use in a room where a water supply pipe is installed on the wall and where a drain port is not normally installed, such as a computer room. This relates to a floor drain fitting that drains water leakage caused by problems with the cooling engine when a computer is installed.

Most of the computers currently used in the computer room are air-cooled, but due to the lack of data capacity of computers in the future, when new computers are introduced, the air-cooled As the computers in the combi-standers become larger, there is a risk that they will not be able to be accommodated in the computer room.

Therefore, in order to solve this situation, we introduced a water-cooled computer and connected the water supply pipe installed on the wall to the computer's cooling engine, thereby reducing the space occupied by the cooling engine by one room. Therefore, it is thought that there will be an increase in the number of new constructions, extensions, and renovations of computer rooms that assume the introduction of water-cooled computers. It becomes necessary to install a floor drain port in the floor to drain water leakage from the cooling engine in case of an emergency such as a crack occurring in a water supply pipe or the like in the cooling engine.

However, floor drains generally have perforated plates facing the floor and road surfaces, and a perforated plate holder that receives the perforated plate has a metal fitting buried under the floor, and the perforated plate holder connects the metal fitting and the drainage branch pipe. connect,
The drainage branch pipe and the drainage branch pipe connected to other floor drains buried in the adjacent room etc. are merged and connected to the main drainage pipe, so the floor drain can be used in the computer room mentioned above. That is not possible.

This is because computer rooms are generally kept at +5% relative to atmospheric pressure in order to keep the interior of the room clean.
Since the air pressure is maintained at u~+l□nAq to prevent dirt and dust from entering from outside, when the above-mentioned floor drain is installed on the floor, the floor drain is installed through the perforated plate. If the drain pipe is always open and the drain branch pipe is in communication with other floor drains buried in adjacent rooms, the air pressure in the room cannot be maintained, making it impossible to maintain an environment suitable for a computer room. There isn't.

A predetermined amount of water is stored at the bottom of the floor drain hole like an S-type trap. There are some types of air conditioners, but these types can maintain a specified air pressure indoors.
Since water evaporates, it has the disadvantage that it cannot fulfill its original purpose after long-term use.

■ ＜￥゛ しYO° TORU ili When a water-cooled computer is introduced into a computer room, the present invention maintains the necessary air pressure in the computer room under normal conditions, and also prevents cracks that occur in the water supply pipes of the computer's cooling engine. In the event of an emergency in which water leaks from a cooling engine due to a problem, it is an object of the present invention to provide a floor drain fitting for quickly draining such water leakage.
