Definitions
- the invention relates to a portable extinguishing gun which has an extinguishing nozzle head equipped with extinguishing nozzles, the extinguishing nozzles being connectable to a supply line.
- extinguishing pistols are used in stationary or mobile fire extinguishing devices in which the extinguishing fluid is sprayed onto the source of the fire via an extinguishing nozzle.
- the extinguishing fluid exits with a relatively high kinetic energy.
- the advantage of using such an extinguishing fluid jet is that the extinguishing agent jet can be introduced into the area of the fire with a long range. In this way, the fireman who operates the extinguishing system is exposed to only a low risk of injury. In order to achieve this, water damage caused by the large amount of extinguishing agent required to extinguish a fire has always been accepted as inevitable.
- an extinguishing nozzle holder which is to be fastened in a stationary manner is known from international application W094 / 25112, in which the extinguishing nozzles are arranged on an inclined, conical outer surface.
- the advantage of such a design of the extinguishing nozzle holder is that a relatively large volume of space can be briefly covered with extinguishing fluid via the extinguishing nozzles.
- the object of the invention is to improve an extinguishing gun of the type mentioned in such a way that the amount of fluid required to extinguish a fire is reduced with an increased effectiveness of the fluid mist.
- extinguishing nozzles which produce a finely divided extinguishing mist.
- This extinguishing mist is optimally composed, inter alia, with regard to the type and size of the individual mist droplets contained in it.
- the extinguishing gun according to the invention makes it possible to adapt the type and composition of the extinguishing mist generated to the requirements which change as the extinguishing progresses, during the extinguishing operation.
- This is achieved in that the extinguishing nozzles of the extinguishing nozzle head can be acted upon individually and / or in groups with extinguishing fluid.
- different extinguishing nozzle combinations can be used to generate an extinguishing mist composed of a wide range of different fluid droplets.
- an extinguishing mist which is composed of only a single, particularly finely divided droplet shape.
- opening additional nozzles can result in this fine Larger drops are added to fog, for example to directly fight nests of embers.
- the individual extinguishing nozzles can be arranged next to one another in a line. This can be favorable for those cases in which a uniform extinguishing fog exit is desired over a large area.
- the nozzles can also be arranged on the circumferential line of an arc of a circle or on a closed circle.
- An embodiment which is advantageous with regard to easy maintenance of the extinguishing gun is characterized in that the extinguishing nozzle head is detachably fastened to a carrier unit.
- the rapid distribution of the extinguishing mist in as large a space as possible can be promoted in that at least a certain number of extinguishing nozzles are arranged on a surface section of the front end face of the extinguishing nozzle head that recedes obliquely backwards.
- the speed at which a volume of space can be filled can be increased that the extinguishing nozzle head has a side face on which at least one extinguishing nozzle is additionally arranged.
- Figure 1 is an extinguishing nozzle head in a front view.
- Fig. 2 is an extinguishing gun in a partially broken longitudinal section.
- the transportable extinguishing pistol shown in FIG. 2 has an extinguishing nozzle head 1, which is rotationally symmetrical and has an end face 2 on its end face S.
- a recess 3 is formed in the center of the end face 2 and receives a central extinguishing nozzle 4.
- the central extinguishing nozzle 4 is screwed into a screw receptacle 5 of a carrier unit 6, which is connected to a first supply line 7 and is fastened to the housing tube R of the portable extinguishing gun L.
- a circumferential surface section 8 is integrally formed on the end face 2, which is conical and retreats at an angle ⁇ with respect to the front end face 2. Extinguishing nozzles are on the surface section 8
- the extinguishing nozzles 9 are arranged at regular angular intervals ⁇ to one another on a circle K which is aligned concentrically with the opening 4a of the central extinguishing nozzle 4.
- the extinguishing nozzles 9 When the supply line 10 is pressurized, the extinguishing nozzles 9 generate an extinguishing mist in which the individual liquid droplets have a small volume and are finely divided from the Exit nozzle openings 9a of the extinguishing nozzles 9 in the vicinity of a source of fire.
- a radially circumferential side surface 12 adjoins the surface section 8 of the end face S of the extinguishing nozzle head 1.
- the extinguishing nozzle heads 13 are also releasably seated in screw receptacles 14 and can be replaced in a simple manner when worn.
- the extinguishing nozzles 9 can be acted upon together as a group with extinguishing fluid via the second supply line 10.
- the extinguishing nozzles 13 are acted upon together as a group with extinguishing fluid via the third supply line, not shown. This enables the central extinguishing nozzle 4, the group formed by the extinguishing nozzles 9 and the group formed by the extinguishing nozzles 13 to be supplied with extinguishing fluid independently of one another.
- valve combination V which is not explained in more detail, is provided.
- the outlet channels of the valve combination V with the supply lines 7, 10 and the third supply line, not shown, assigned to the two supply lines 7, 10 and the third supply line, not shown, are provided via an intermediate disk 20 provided with oblique bores connected.
