Description

In the drawing, FIG. 1 shows a section of the proposed fire extinguisher; F. 2-t separate type of metal cylinder in which a hermetically sealed container with acid is inserted; FIG. 3 is a cross section along the line p - i in FIG. 2; FIG. 4 and 5, a modification of the fire extinguisher, in which a small, completely perforated cylinder with a vessel enclosed in it for an acid is inserted into a metal cylinder, having a small number of outlets.

Existing fire extinguishers from a firing pin: 1I and with a hermetically sealed acid cylinder are fitted with a cylinder into which a vessel with acid is placed. Due to the fact that this cylinder is completely perforated, the acid spills out immediately, and the pressure in the device reaches its maximum almost instantly. This design of the apparatus does not allow the composition to produce foam when joining, since: 1) to form a foam, it is necessary not to have a fast acid flow and 2) the outlet must not have any tubes inside the apparatus, but must be located at the end where Acidic acid is combined with alkaline.

The proposed fire extinguisher shown in FIG. I, 2 and 3, consists of a reservoir A with an alkaline liquid, a cylinder B. It can be supplied; With a loose guide rib, a sealed cylinder C with acid, and a bolt D with a hammer with an imbalance are inserted into this cylinder. Cylinder B

, has a small number O at the top, located on the side opposite the outlet

I / apparatus. To ensure that cylinder B always has a fire extinguisher

: it is correctly put into place, on it the edge D can be made (fig. 1). the corresponding recess in the gate.

The described fire extinguisher operates as follows. Turning it upside down, hit the button with something with the shutter button D, then the font (/. Passage through the seal of the shutter will break the acid cylinder in cylinder B, and the latter will pour out through the hole O into the alkaline

a liquid, the foam that has formed through the outlet (s) will be thrown out. Due to the small number of openings O, the acid will not immediately pour out, which makes it possible to form a foam from the alkaline composition and the pressure in the device will be held more or less evenly.

FIG. Figures 4 and 5 show the modification of the fire extinguisher, namely, that the acid vessel is placed in the entire holey cylinder M, which, together with the acid vessel, is inserted into cylinder B. The latter may have one or more holes O. The action of this device is as follows; when the cylinder of acid is broken, the latter through the perforated cylinder will flow into cylinder B and from there through one or more

the holes O will be combined with an alkaline liquid in vessel A.

SUBJECT OF INVENTION.

1) A fire extinguisher fitted with a hammer and an acid bottle, characterized in that the metal cylinder .6 in which the acid cylinder is placed has holes ли щ щ на on a small part of its surface opposite the outlet / apparatus (Fig. 1-3 ).

2) In the fire extinguisher specified in clause 1, the cylinder B is supplied with a guide edge fC (Fig. 1) for its installation during assembly of the device.

3) Modification of the fire extinguisher specified in paragraph 1, characterized in that the vessel with the acid is placed in a completely perforated cylinder M, inserted into cylinder B (phi1. 5).
