CO2 Automatic Diffusion Fire Extinguisher for Electric Panel {ELECTRIC PANEL CO2 AUTO EXTIGUISHER}

The present invention relates to an electric panel CO 2 automatic diffusion fire extinguisher, and the carbon dioxide gas is filled in the fire extinguisher container to emit carbon dioxide gas due to the internal gas expansion pressure increase during operation of the fire extinguisher.

At this time, the carbon dioxide gas filled with the extinguishing agent is radiated into the gaseous form of fine particles by the auto-diffuser heat sensing high-pressure open gas injection head.

The gaseous particulates using gas are extinguishing agents that have excellent asphyxiation effect, penetration power, air blocking and cooling effect on fire source, and use small amount of chemicals to quickly start fire by heat-sensing open gas injection head when fire occurs in electric switchboard and control panel. The advantage is that it can evolve.

The automatic diffusion fire extinguisher for electric panel is the existing gas fire extinguisher Halon, NAFS-Ⅲ, Inergen, FM-200, etc. Interlocking arrangements should be provided.

Therefore, it is unsuitable for the narrow space and uneconomical.

The present invention is a fire extinguisher that supplements the problems and disadvantages of the existing gas fire extinguisher

First, the excellent performance of fire suppression and fire extinguishing

Second, it is A, B, C class fire extinguishing and electric non-conductivity to general fire, oil, gas fire, electric fire by radiation, and it is excellent fire extinguisher for cooling and suffocating effect.

Third, if a small amount of extinguishing agent can be used to extinguish the fire quickly in the event of a fire in the electrical panel, economical efficiency is guaranteed at a low cost of medicine.

Fourth, in the medicine refilling method of the used fire extinguisher, eliminating the filling cost of the existing fire extinguisher and the cumbersomeness of the filling method, and injecting CO2 gas, which is a fire extinguishing agent, directly into the used fire extinguisher, so that the refilling is completed, the pressure-sensing heat-sensing high-pressure open gas Develop and install the spray head.

The carbon dioxide emitted is introduced into the heat-sensing high-pressure switch type injection head through the high-pressure flexible hose by opening the actuator valve through the gas which is the extinguishing agent filled in the chemical container.

When the heat is sensed by the heat-sensing open gas injection head installed through the electric panel hole at the end of the high pressure flexible hose, the sealing film head is separated and the gas is emitted.

The CO2 automatic diffusion fire extinguisher exclusively for electric panel has the features of small dosage, small area, fire extinguisher and electric panel direct connection, high pressure flexible hose connection using distributor, and the characteristics of the fire extinguisher according to the fire extinguishing function are for the purpose of the present invention.

The prior art has the following problems.

Fire extinguishers that emit carbon dioxide or halon are not toxic in living rooms or offices with less than 20 m2 of windowless, basement and floor areas. Therefore, installation location and environmental restrictions are imposed.

Carbon dioxide (CO ₂ ) fire extinguisher has a disadvantage that the weight is heavy and the handling of the high pressure gas is not easy because the high pressure gas container.

Haron fire extinguishers are often used for electric fires such as carbon dioxide, but the price of fire extinguishers is high due to the import of gas. In addition, Halon, which is designated as an environmentally regulated gas, has problems in repairing and filling existing fire extinguishers as a target for developing alternative substances due to import restrictions and production stoppages.

In order to achieve the above object, the present invention opens a screw down valve for injecting CO 2, which is an addressing chemical, into a chemical container, and injects CO 2 into the chemical container using an actuator valve gas opening. At this time, the amount of gas injects a prescribed amount such as radiation dose.

Here, the opening of the actuator valve grabs the screw down valve operating lever and turns to the left to open the carbon dioxide gas and the outside in the actuator valve medicine container. At this time, the drug container and the outside is at atmospheric pressure, if the external injection pressure is high, the injection of the drug container is made easily. When the injection of the drug is completed, the internal pressure is filled.

The actuator valve is opened by the operation of the screw down valve operating lever, and the down valve screw is raised upward, and the internal pressure of the chemical container injected with carbon dioxide gas is opened to the outside and atmospheric pressure.

At this time, carbon dioxide gas can be injected through the opening of the actuator valve gas, and when a certain pressure necessary for spinning is filled, the needle guide of the pressure gauge attached to the high pressure open type injection head indicates the right side when stopping the carbon dioxide gas injection.

At this time, the screw down valve is kept in a closed state before the operation lever is kept in a downward state before operation and becomes a different operating standby state in the filling of the drug.

When the filling operation of the drug is completed in the above order, the high pressure flexible hose suitable for the male thread for the hose coupling of the actuator valve is combined. The auto diffusion fire extinguisher, which has been filled, is ready for use.

The operating method is a simple CO2 automatic diffusion fire extinguisher filled with chemicals, depending on the environment of the electric panel control panel and the distribution panel to be radiated. In the direction of rotation, the actuator valve is opened and carbon dioxide gas is filled to the connection hose with the high pressure open gas injection head. At the time of fire, if the ambient temperature is over 72 °, the bimetal sealing film of the high pressure open type injection head detects heat. When the sealing film of the head senses heat, the expansion pressure of the carbon dioxide gas filled in the chemical container rapidly rises above 60 bar, and the gas is emitted to the target by removing the sealing film of the high-pressure open gas injection head through a hose connected to the actuator valve. .

The extinguishing agent of carbon dioxide gas in the gaseous state emitted to the target also cools and suffocates the general fire, the oil fire, and the electric fire.

There are many advantages compared to the existing fire extinguisher as described above, the present invention will be described in detail with reference to the accompanying drawings.
