2402 is roughly classified into a halon-based or an aqueous solution digestion agent containing a strengthening solution containing an aqueous potassium carbonate solution as a main component, a fluorine surfactant, a silicon surfactant, and the like. Any extinguishing agent is mixed with a propellant, and the content of the extinguishing tool contents is gaseous or liquid.

形式で商品化されて来た。These aerosol type simple fire extinguishers have the same mechanism as general aerosol products such as hair sprays and insecticides,
That is, one valve has both a gas filling function and a radiation function. If the contents of the fire extinguisher are gaseous or liquid, the amount of the contents remaining inside the valve mechanism such as the stem hole, stem rubber, housing after operating the valve is small,
Since it does not block the stem hole or interfere with the valve opening / closing mechanism even if it remains, it has been commercialized in the form of an ordinary aerosol mechanism.

る。Various general aerosol containers whose aerosol contents are not limited to fire extinguishing agents are known.
For example, Japanese Patent Laid-Open No. 631388 discloses an aerosol container in which a valve and a button are attached to each of a canopy and a bottom cover of the aerosol container so that the container can be ejected in an upright state and an inverted state. Further, in Japanese Patent Laid-Open No. 60-158073,
Disclosed is an isolation type aerosol container having a double structure by providing a space isolating means such as a bag in the aerosol container. The aerosol of this double structure system is an invention that stores different medicines in each isolation space and tries to mix these medicines at the time of use. An opening member is provided in the space in which the medicines, the propellant and the like are stored in the bottom lid. Disclosed is a container in which this space is destroyed at the time of use and is mixed with a drug or the like in another space.

るため生産性が悪く、品質の安定が得られなかった。On the other hand, about 5 products are classified as an aerosol in which the drug is not for extinguishing but for spraying powder for other purposes.
There is only a product in which talc powder of 0 μm or less is suspended in liquefied gas at 10 wt% or less. The development of an aerosol-type fire extinguisher using a powder extinguishing agent such as potassium bicarbonate, monobasic ammonium phosphate and sodium bicarbonate has been conventionally made. For example, from 1964 to 1966, after measuring the powder fire extinguisher in the aerosol container, dry ice was quickly measured and put into the container, and then the valve was clinched to seal the container. Was tried. In this system, dry ice is vaporized in a container to bring the container into a pressurized state so that the product pressure is about 6 to 8 kg / cm 2 . In this method, since dry ice is measured in the atmosphere, the measurement becomes inaccurate due to a decrease in weight due to rapid vaporization, and the inclusion of water due to the adhesion of moisture in the atmosphere is inevitable. For this reason, there was a large variation in the product pressure, and the fluidity was lost due to the solidification of the powder fire extinguishing agent due to moisture absorption, and injection was impossible. Further, since this method is a manual work, the productivity is poor and the quality cannot be stabilized.

顕著であった。Therefore, in order to solve the above-mentioned drawbacks, a system has been tried in which a powder fire extinguishing agent is stored in a container in advance, and then the propellant is vaporized or liquefied and charged through a valve. In this method, the powder extinguishant sucked up from the dip tube when the valve is actuated when the propellant is filled or when the internal pressure is checked, etc., inside the valve mechanism, that is, inside the stem hole, housing, stem rubber It has become a cause of defects such as remaining in, clogging, and leakage. In particular, this phenomenon was remarkable when the particle diameter of the powder fire extinguishing agent was about 100 μm or more.

に経時の容器内部圧を確保することができる。In the present invention, the valve of the extinguishing agent radiating member in the step (1) is dedicated to extinguishing agent emission, and the valve of the propellant filling member in the step (3) is dedicated to propellant filling. That is, the feature of the present invention resides in that a valve dedicated to extinguishing agent discharge is provided at one end of the aerosol container, and a valve dedicated to filling the propellant is provided at the other end of the container. It is possible to manufacture a powder fire extinguisher aerosol-type simple fire extinguisher excellent in productivity while maintaining the airtightness, preventing the powder fire extinguisher from clogging, and stably securing the pressure inside the container. Since the extinguishant radiation valve is not used until extinguishing, the powder extinguishant does not enter the valve mechanism when the propellant is filled. In addition, the propellant valve is completely sealed by installing a screw seal plug after filling the propellant, so the propellant leak is completely prevented, and the propellant filling valve is locked by this and cannot operate in the future. At the same time, the pressure inside the container over time can be secured.

例示できる。The container having openings at both ends used in the step (1) of the present invention is usually a cylindrical container, but is not limited thereto. Further, in order to fix the extinguishant radiating member to the opening, the container is generally erected (the side surface of the container is vertical), and the member is attached to the opening above the container, but not limited to this. As the valve used for the fire extinguishing agent radiating member, a normal valve used for aerosol products can be applied, and examples thereof include a push-down type, a tilt type, and a female type.

The extinguishant emitting member is fixed together with the sealing member by a conventionally known sealing means. The sealing member constitutes the top of the container. In the step (2) of the present invention, the powder fire extinguishing agent is filled from the other opening of the container. At the time of this filling, the container is usually turned upside down so that the opening is at the top, but the method is not limited to this as long as the powder fire extinguishing agent is filled. After the powder fire extinguishing agent is filled, a cleaning step for removing the fire extinguishing agent adhering to the peripheral portion of the container may be provided.

抗を少なくし、消火効果を上げることが出来た。The powder fire extinguishing agent to be filled is preferably a salt having a flameproof property, and examples thereof include potassium bicarbonate, ammonium monophosphate, sodium bicarbonate and the like. The quality assurance period for aerosol type simple digesters is normally 3 to 5 years from the date of manufacture, during which product pressure, valve function,
Product functions such as fire extinguishing agents must be maintained normally. The injection valve has a high radiation level and a radiant distance.
In order to achieve the designed fire extinguishing ability such as the radiation time and the total injection amount, normal functions must be maintained. In order for the valve to maintain a high level of airtightness, it is necessary to prevent foreign matter such as powder from remaining or adhering to the inside of the valve mechanism until the fire is extinguished. To make the radiation distance and radiation time as a fire extinguishing function effective, use a valve stem hole, dip tube, etc. with a large diameter (about 5 mm), and resistance when passing through the valve, dip tube, stem hole It was possible to improve the fire extinguishing effect by reducing the amount of fire.

射剤が均一混合を行ううえで好ましい。The propellant filling member is fixed together with the sealing member by a conventionally known sealing means, and the sealing member constitutes the bottom of the container. Since the propellant filling member has a dip tube having an inner diameter of 3 to 4 mm, the propellant of compressed gas such as nitrogen and carbon dioxide is uniformly dispersed in the powder fire extinguishing agent, and the powder agent is hardened. It is effective for prevention and is preferable for uniformly mixing the extinguishant and the propellant.
