Description

{Indoor hydrant outlet}

The present invention relates to a waterproofing hole for indoor fire extinguishing, and more particularly to a waterproofing hole for indoor fire extinguishing which is suitable for making opening and closing operations convenient and preventing leakage of water.

In general, indoor fire hydrant facilities are installed in fire-fighting buildings, and in the event of an emergency, the firepower is suppressed by the own personnel of the building in an emergency. Various structures are constructed according to the structure and use of the building. Battleships, fire-fighting piping, and emergency power sources.

The fire hydrant box has a fire hydrant and a fire hydrant hose embedded therein. The fire hydrant can be called a fire hydrant valve or an angle valve. The fire hydrant can change the flow of the fluid by 90 °. The fire hydrant can be installed in a fire hydrant box, And the fire hydrant hose is connected to the other side, and when the fire hydrant is opened at the time of fire, the fire extinguishing water is discharged to the outside through the fire hydrant hose.

The valve body is provided with a cap on an upper portion of the valve body, and a valve rod having a handle at the center of the valve body is installed to ascend and descend by rotation. When the valve rod is rotated from the cap to the left, The packing of the valve body installed is separated from the valve seat of the valve body so that the fire hydrant opening is opened. On the other hand, when the valve body is rotated to the right, the packing closely contacts the valve seat of the valve body so as to close the flow path of the fire water coming into the inlet.

However, the above-described conventional techniques have the following problems.

The conventional fire hydrant opening is structured such that the valve rod is screwed up and down. The valve rod is screwed up and down to control the discharge of water for fire extinguishing.

Since the valve rod is moved up and down as described above, high pressure water pressure is applied to the high-level valve, so that the valve rod is moved up and down to make operation difficult, and it is very difficult to turn the valve rod in order to raise and lower the valve rod in actual fire.

In particular, since a large hydraulic pressure is applied to the operation of closing the valve rod by lowering it, it is more difficult to close the valve rod.

In addition, there is a problem that the close operation itself is very strong because the high-pressure water pressure is pushed.

In addition, when the valve rod is lowered, a very large pressure acts upon closing the watertight port, so that there is a problem that the packing is pushed by the high pressure and leakage occurs.
