Description
The present invention relates to a safety pressure reducer for a compact compressed gas container, and more particularly, to control the amount of gas ejected while easily ejecting compressed gas or compressed air stored in the container through a pressure reducer in a timely manner, When a high temperature or high pressure state due to the like, the pressure reducing device of the compressed gas container to eject the overpressure gas to the outside through a safety device provided on one side of the pressure reducer to prevent the container from exploding.
In the event of a fire in the subway or in an enclosed space, most casualties are asphyxiation due to toxic gases. In order to prevent asphyxiation during a fire in such an enclosed space, there is a method of wearing a gas mask, which does not filter all kinds of toxic gas, and there are few places where a gas mask is equipped and the wearing process is inconvenient. little.
In order to solve this problem, a new concept air respirator having a compact compressed gas container containing air or oxygen has been developed to block the toxic gas and maintain breathing while being easy to install and easy to wear.
In general, a method of storing and supplying a gas is to charge or liquefy and store the liquid in a high pressure state in a special container, and to supply the gas at a proper consumption pressure using a pressure regulator such as a regulator as necessary.
In the conventional pressure reducing device, it is common to open and close the pressure reducing valve by rotating a knob such as a knob, but unlike usual, it is expected that the pressure reducing valve is adjusted as usual because there is no confusion in case of an emergency such as a fire. I can't.
Therefore, the air respirator equipped with compressed gas in case of emergency such as a fire needs to supply the compressed gas to the wearer by depressurizing the compressed gas to a pressure suitable for automatically breathing by one touch without any additional manipulation. There is this.
The air respirator with compressed gas is compressed and filled with breathing gas such as oxygen, so if the storage area itself is fired or exploded at high pressure, it can cause fatal damage to nearby facilities or people. If the pressure is higher, some or all of the gas in the container is discharged to the outside to prevent the explosion is necessary.
In addition, the above life-saving equipment is essential for long-term performance because it is not used at all times but only for emergencies, but it may not be able to function properly in case of emergency, because gas leakage may occur due to incomplete sealing of the pressure reducer. There is this.
The present invention is to provide a decompression device for supplying breathing maintenance gas at a proper pressure to the wearer by reducing the high-pressure compressed gas with one touch in an emergency such as a fire in a life-saving air respirator equipped with a compressed gas do.
In addition, the present invention is to prevent the explosion of the gas container by ejecting the over-pressure gas in the gas container to the outside through the pressure reducer when pressure is applied from the outside to the small gas container or excessively high pressure in the gas container due to the temperature rise. It is intended to provide a safety device for a compressed gas container.
In addition, the present invention is to provide a pressure reduction device and a safety device that maintains a sealed state to maintain long-term performance while automatically or manually ejecting and decompressing the gas in the event of an emergency.
