In order to achieve the above object,

The screw down valve 101 for injecting CO 2, which is the chemical agent, is opened in the chemical container 103 to inject the CO 2 into the chemical container using the actuator valve 102b gas guiding flow path. At this time, the amount of gas injects a prescribed amount such as radiation dose.

Here, opening of the actuator valve 102 grabs the operating lever of the screw down valve 101 and turns it to the left to open the carbon dioxide gas 109 and the outside in the actuator valve 102 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 opening of the actuator valve 102 is caused by the operation of the screw down valve 101 operating lever so that the down valve screw is upward, and the internal pressure of the chemical container in which the carbon dioxide gas 109 is injected is opened to the outside and atmospheric pressure.

In this case, carbon dioxide gas 109 may be injected through the guide flow path of the actuator valve 102b, and when a constant pressure necessary for spinning is filled, the carbon dioxide gas 109 may be attached to the high pressure open type injection head 107 when the injection of the carbon dioxide gas 109 is stopped. Of the pressure gauge 108 is indicated to the right.

At this time, the screw down valve 101 is moved to the position according to the maintenance of the closed state, the operating lever is maintained in the down state before the operation and becomes another operating standby state in the filling.

When the filling operation of the drug is finished in the above-described sequence, the high pressure flexible hose 105 suitable for the high pressure flexible hose coupling male thread 102a of the actuator valve 102 is coupled. The auto diffusion fire extinguisher, which has been filled, is ready for use.

The operating method is a screw-down valve 101 operating lever, which is selected by attaching a simple CO2 auto-diffusion fire extinguisher filled with chemicals to a wall side method and an upper surface method one by one according to the environment in which the electric panel control panel and the distribution panel are attached. When grasped and turned to the left direction, the actuator valve 102 is opened to fill the carbon dioxide gas 109 to the connected high pressure flexible hose 105 to which the high pressure open gas injection head 107 is attached. At this time, if the ambient temperature is 72 ° or more when a fire occurs, the bimetal sealing film of the high-pressure open type injection head 107b detects heat. When the sealing film of the head senses heat, the expansion pressure of the carbon dioxide gas 109 filled in the pharmaceutical container is rapidly increased by 60 bar or more, and the high pressure flexible gas 105 connected to the actuator valve 102 opens the high pressure open gas spray head ( By removing the sealing film of 107, gas is emitted to the target.

The extinguishing agent of the carbon dioxide gas 109 in the gaseous state radiated to the target also cools and smothers the general fire, the oil fire, and the electric fire.
