Description

  The present invention relates to a fire extinguishing agent tank that stores a fire extinguishing agent inside and discharges the extinguishing agent to the outside by a pressure gas or the like.

  Large fire extinguishing agent tanks and small portable extinguishing agent tanks installed in fire extinguishing equipment are provided with an inner bag filled with foam extinguishing agent or gel-containing extinguishing agent in the extinguishing agent tank. There is a system in which pressure gas or the like is filled between the inner wall of the tank and the inner bag, and the extinguishing agent in the inner bag is pushed out by the pressure. This type of fire extinguishing agent tank requires a wide opening to allow the inner bag to enter the tank. In general, a flange lid as shown in Patent Document 1 in which the tank diameter is an opening is used. However, since the pressure resistance of the flange lid is low, the thickness must be increased considerably, and the entire tank is very large. It was getting heavy. In addition, the number of bolts corresponding to the diameter of the flange lid is required to fix the flange lid to the fire extinguisher tank, and when replacing the inner bag, remove those bolts to remove the flange lid. There is a need. The work is laborious and the bolts, nuts, washers, etc. may fall off.

  On the other hand, as shown in Patent Document 2, when a screw-in socket or the like is used, the weight of the entire fire extinguisher tank is lighter than that of the fire extinguisher tank employing the flange lid. However, since the opening becomes narrow, it is difficult to put the inner bag, and it is expected that it takes time to fill the extinguishing agent even after the inner bag is put in the tank. Also, because it takes time and equipment to fill the fire extinguisher tank that has been emptied at the fire site, etc., it is necessary to prepare several replacement fire extinguisher tanks at the time of the battle. It can be costly.
