Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an overpressure device for automatically opening and closing a cover,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an over-pressure automatic opening and closing lid apparatus having a lid closing function, and more particularly, The cover is opened by the overpressure by setting the pressure to protect it, and the cover which is opened by the overpressure is not limited by the opening ratio which is opened by the overpressure. The present invention relates to an over-pressure automatic opening and closing lid apparatus having a lid closing function for preventing hot smoke generated by a fire through a duct and high-temperature smoke containing toxic gases from entering the smoke-inducing area.

When the fire is extinguished by fire extinguishing agent in the event of a fire, the pressure is expanded by the chemical and the heat, so that the building can be protected to prevent the loss of expensive equipment or facilities. The device was installed in a facility using fire extinguishing gas.

Facilities that use fire extinguishing gas include storing or storing valuable cultural assets and treasures such as documents storage rooms, libraries, computer rooms, communication facilities, etc., which can not be recovered if they are drenched in places where electric facilities such as electric, substation, power generation room, It is equipped with gas extinguishing facilities to store expensive assets such as museums and other places where flammable liquids or dangerous materials are stored, and to evolve fires in case of fire.

The gas fire extinguishing system is equipped with means for blocking outdoor air inflow such as a fire shutter or an automatic shut-off device that blocks the inflow of outside air into the protected area in case of fire, and fire extinguishes by spraying fire extinguishing gas into the protective area.

The fire extinguishing gas of the gas fire extinguishing system increases the specific gravity of the inert gas in the air to lower the oxygen concentration in the air, and the fire extinguishing gas which is injected in the low temperature state during the fire expands the fire by cooling the surroundings.

Air consists of about 21% oxygen, 78% nitrogen, and 1% other materials, and oxygen in the air promotes combustion (oxidation).

The fire extinguishing gas lowers the oxygen concentration of about 21% of the air to about 15% or less, and the fire is suppressed by lowering the ambient temperature while spraying the low temperature extinguishing gas (inert gas) stored in the high pressure container in the high pressure or liquid state .

It is stipulated that an overpressure outlet should be provided in the Fire Service Act in consideration of the fact that the inert fire extinguishing gas injected in the event of a fire is expanded and the pressure of the protection area is increased to destroy expensive equipment and facilities.

Korean Utility Model Publication No. 2014-06131, which is based on the above-mentioned fire fighting law, has a frame for embedding and fixing in a pressing hole formed on a wall, and an opening / closing plate moving forward and backward on one side of the frame to open / And a plurality of supporting bolts are fixed to the opening and closing plate, and the connecting bolts are movably inserted into the engaging holes of the respective supporting members, A coil spring is coupled to the connection bolt movably inserted into the engagement hole of the retainer coupled to the opening / closing plate, and a washer and a nut for supporting the coil spring coupled to the connection bolt are coupled to the connection bolt end .

However, in the prior art constructed as described above, the width of the open / close plate is limited due to the tension of the spring provided at the side end thereof while the open / close plate is opened. Thus, the opening is not smooth, and when the open / close plate is opened, There is a problem that opening is not smooth.

When the open / close board is opened, a resistance force is generated due to the tension of the spring fixed to the frame, and thus the open / close board can not be opened properly.

In addition, when the hot smoke containing toxic gas or heat generated by the fire flows into the smoke-inducing section through the duct, the prior art has a problem that the hot smoke and heat are directly introduced into the smoke-inducing section,

The prior art has a problem in that it can not fundamentally block the heat generated by the high-temperature smoke containing the induction gas and the fire.
