Description

  The present invention is a mobile powder that can extinguish a fire when a person moves to a fire source with a hose when a fire breaks out and releases the powder fire extinguishing agent in a chemical container stored in a storage box from the hose by pressurization. It relates to fire extinguishing equipment.

  Mobile powder fire extinguishing equipment is normally closed with a chemical container for storing a powder fire extinguishing agent and a flexible hose (for example, the root part and the tip part of the hose) for extracting the powder extinguishing agent from the chemical container. And a nozzle for releasing the fire-extinguishing agent toward the target location, provided at the tip of the hose. In order to obtain a pressure for releasing the fire-extinguishing agent, the drug container is provided with a pressurization gas container containing a pressurization gas, and a set of the drug container, hose, nozzle and pressurization gas container is provided. There is a mobile powder fire extinguishing equipment housed in a storage box with an open / close door (see, for example, Patent Document 1).

  When a user uses a mobile powder fire extinguisher in the event of a fire, first open the door of the storage box and turn the handle of the pressurized gas container to open the container valve. By this operation, the gas flows from the pressurizing gas container into the medicine container, and the inside of the medicine container is pressurized by the gas. Next, the on-off valve on the root side of the hose is opened, so that the fire extinguishing agent and the pressurizing gas are filled in the hose.

  Mobile powder fire extinguishing equipment is mainly installed in parking lots and aircraft hangars. The feature is that it is useful for a large-scale fire in a wide space by providing a large-capacity drug container and a long hose as compared with a powder fire extinguisher that can be carried by the whole body. In use, pulling only the hose to near the source of the fire and releasing a large amount of powder fire-fighting chemical sent from a chemical container fixed to the containment box from the hose makes it possible to expedite a large-scale fire that has occurred in a large space. Can be extinguished.

  The law stipulates that mobile powder fire extinguishing equipment should be inspected every six months and be inspected once a year so that it operates normally in the event of a fire. In particular, there are cases where malfunctions occur when the valve of a gas container for pressurization has been installed for years, and mobile powder fire extinguishing equipment is used in the state where such a malfunction occurs. Then, the pressure required for the release of the fire extinguishing agent cannot be obtained, and the function as the fire extinguishing equipment cannot be exhibited. Therefore, it is necessary to periodically check that the container valve can be opened and closed normally.

  In this container valve inspection, the gas container for pressurization is once removed from the drug container main body, the gas outlet of the container valve part of the gas container for pressurization is closed by temporarily attaching an inspection jig, and the handle of the container valve Turn to check if it can be opened and closed normally. After completing the confirmation work, turn the handle of the container valve to close the valve, remove the inspection jig while exhausting the space between the container valve and the inspection jig, and reinsert the pressurization gas container into the drug container. Attach to the end of inspection.

  Here, in the inspection of the container valve of the gas container for pressurization, since it is necessary to open and close the container valve once, a small amount of gas in the gas container for pressurization will be lost. There is no problem as long as the amount of gas necessary to secure the is maintained. And, for the internal pressure of the gas container for pressurization in the mobile powder fire extinguishing equipment and the number of possible inspections, the allowable standards are set by each manufacturer. For mobile powder fire extinguishing equipment that falls below the standard internal pressure or exceeds the allowable number of inspections, The pressurized gas container is replaced with a new one.

  In many cases, the inspection of the container valve of the gas container for pressurization is performed on the same day for a plurality of units, and various checks other than the opening / closing inspection of the container valve are also performed at the same time. Therefore, it is necessary to work efficiently to finish the inspection within a limited time, but the work of removing the gas container for pressurization from the main body of the drug container once and reattaching it as in the above inspection method It takes time and is inefficient. In addition, a special inspection jig must be prepared, and it is necessary to secure a means for safely exhausting the high-pressure gas accumulated between the container valve and the inspection jig after the inspection. There are problems with the cost and safety during inspection.

  Therefore, when inspecting the container valve of the pressurization gas container provided in the mobile powder fire extinguishing equipment, there are problems of reducing the time required for the inspection of the container valve and reducing the cost for the inspection.
