Despite the ease of manufacture, the well-known manual fire extinguishing nozzle is not effective enough in operation in the combustion mode, which is due to the design of the working head. In this design, the guide pipes for supplying water in a continuous mode are made non-adjustable and small in size. As a result of strong throttling and a significant pressure drop, the solution water flow acquires the form of a droplet water mist of weak strength and a small dispersion angle. In addition, this working head is designed for use with purified water, since the entry of foreign bodies with dimensions exceeding the size of the outlet hole into the guide channels leads to clogging, requiring the water supply to be stopped and cleaned. channels. This often occurs when taking water from natural sources (river, lake, pond). Naturally, such a stop is unacceptable under fire extinguishing conditions. Also, conditions do not always allow the use of purified water. But water fog does not provide the required effect of creating a curtain for firefighters, and it is ineffective for extinguishing the fire itself.

In addition, the design of the known crane device, when abrasive components enter the zone of contact of the guide device with the hood surfaces, is subject to jamming, which does not allow for efficient and effortless transfer from One water supply mode to another.

This allows to reduce hydraulic resistance and pressure loss when the flow cross-sections of the element and the working head do not match and when switching from one mode to another. The multi-mode crane distribution device is made with a locking mechanism (Fig. 7) of the guide device in the specified operating modes of the shaft, which is a ball lock 21, pressed by a rubber ring 24 in the direction of the grooves. a rocker plate 25 installed in the control handle 20, having an annular projection 26 for pressing the rubber ring to the body 1 of the barrel. In principle, the fixation mechanism can also have a conventional design with the rubber ring replaced by a spring. However, in this case, increased hermetization of the mechanism is required to protect it from moisture ingress. The initial position of the guide apparatus corresponds to the "off" mode, which is shown in Fig. 9, and this mode is demonstrated in the diagram in Fig. 8. In Fig. 8 shows a diagram of the operating modes of the trunk, executed on the hull of the 1st trunk from the side opposite to the location of the control handle. This diagram shows the following modes: mode "0" - "off", the barrel is closed, mode "I" - continuous feed, mode "II" - central compact structure, mode "III" - joint operation of the compact structure and 10

In this mode There is a rapid supply of water to the combustion chamber. At a maximum beam angle of 120 degrees, the peripheral torch-shaped structure forms a protective screen for the operator. When the flame is opened in the range of 15-60 degrees, a concentrated peripheral structure is formed, which can cover a large combustion area, while low-carbon foam is obtained and smoke displacement is facilitated. With a variable change in the angle of the torch spray of the peripheral structure from 15 to 120 degrees, effective protection of the operator is produced, a water suspension is created in a closed volume, and a burning surface is quickly covered in a small closed volume. This mode is most suitable for extinguishing fires in confined spaces. The spherical element of the guiding apate at the corner of the axis 19 is made with a central component 28 (Fig. 11), Designed for direct delivery of water from the hose to the central area of the 5th working head, which corresponds to the “II” mode (fig. 8), This is also the case for the central compact structure. The third mode "III" is determined at the following angular position of the spherical shape of the element (Fig. 12), when the other central hole 29, made with a larger diameter than the first, simultaneously communicates with the sleeve the annular 2 and the central 5 working head blades. This mode corresponds to the combined operation of a compact central structure and a 3 m diameter protective screen with a distribution feed at a maximum opening angle of 120 degrees.

Due to the control valve, the pump separator device 11 flows into position - supply of water or foam composition to the annular zone 2 (Fig. 10) through the separated information 27. In this case in chamber 7 a high control pressure is formed, since this chamber is connected through channel 9 with the annular cavity 2. Under the action of the pressure in the control chamber 7, the piston 6 is displaced forward into the outlet zone and occupies the position shown in Fig. 2 12

The inverted control channel 12 ensures a uniform cross-section in the outlet zone, both at the angle Satisfying the pasta with discharged water meets the required conditions. Complete saturation is possible due to the complete alignment of the plates around the power axis. Due to the fact that the cross-section of the water outlet in the solution mode is limited by the outer rim of the nozzle and the lower part of the element 15 and represents a narrow place, it is possible for this section to become clogged with a foreign body. Regarding a solution like this to eliminate the purchase of water supply, it was necessary to stop the supply of water and through Clean the barrel and clean the bottom channels. For the solution proposed by this invention, it is sufficient to turn off the device 11 s. fast mode to the initial mode (Fig. 8), and then return to the first mode of fast water supply. In this case, when the jet mode is switched on, the increase in pressure in the control chamber 8 will lead to the nozzle returning back and an increase in the flow cross-section, leading to the cleaning of the blockage and the removal of the foreign body. By re-activating the first mode, the entire head is returned to its previous mode. This operation for cleaning the channels is performed without dismantling the barrel and stopping the water supply to the combustion site.

Multi-mode pressure transfer device 11 moves to the same position (Fig. 11) - delivery water in the central part of the 5th century. When the opening 28 of the guide device is aligned with the central cavity and pressure is applied to the sleeve in the control chamber 8, the control pressure is maintained due to the communication of the cavity 5 through the channel 10 with the control chamber 8. In this case, the nozzle, that is, its movable part 4, shifts back and occupies the position shown in Fig. 2 by a solid line. In this way, the flow of water or foam composition is discharged in a continuous manner (central compact state).

The new device is based on the angular position - water supply Simultaneously into the central and annular lobes (Fig. 12). In this case, the pressure through openings 29 and 33 simultaneously enters both control chambers 7 and 8. Due to the fact that the pressure-bearing areas on the piston are the same and the central cavity has a tapering profile, the nozzle moves forward and occupies the position which is shown in Fig. 2 by a dotted line. This is due to the fact that on the conical surface of the walls forming the central cavity, a distribution of forces is produced, the axial component of which causes the nozzle to move forward.

During joint operation, the compact structure is not adjusted and is directly determined by the feed pressure. And the peripheral structure can change up to a maximum torch angle of 120 degrees. At this, at the maximum torch angle, a protective screen with a diameter of 3 m is formed for effective protection of the operator. 14

The new separating device 11 goes to the last position at the angle of the direction - water supply to the annular pepithopheic region and into the central region. This mode corresponds to the previously considered third mode, however, the introduction of the guide blade 32 into the path in the central cavity allows the central part to be expanded, transforming it from compact to expanded with an angle of up to 15 degrees. It is used to cover a large area of the fire source with the maximum water flow. The functionality of the periphery structure in this mode does not change and remains the same as in the previous mode.
