Definitions
- Portable and rollable fire extinguishers with liquid extinguishing agent namely water or foam
- liquid extinguishing agent namely water or foam
- foam extinguishers working fire extinguishers that produce compressed gas consolidated extinguishing foam are also known.
- the known foam extinguisher is not universally applicable and, for example, only very limited suitable for extinguishing fires in live systems.
- the invention is therefore an object of the invention to provide a portable or mobile foam extinguisher, which is at least improved to the effect that the foam consistency is adjustable according to the particular needs.
- either the Schaumverfestologist can optionally be switched on or off in operation and preferably continuously adjusted between a minimum value and a maximum value.
- the consistency of the foam can thus be optimally adjusted according to the needs.
- the compressed gas admixing valve for producing the foam consolidation is attached to the extinguishing agent container so that only one hose from the extinguishing agent container, namely from the admixing valve attached thereto, extends to the extinguishing pistol.
- a switchable nozzle assembly to work either with a bundled compact droplet jet or with a more or less finely atomized broader spray.
- a pivoting mechanism may be provided for selectively using a foam tube or a spray jet tube.
- the foam tube may also be provided at its upstream end with air inlet openings whose opening cross-section is infinitely adjustable by an adjusting sleeve between a fully closed and a fully open position.
- a separate fillable foam container is provided in the fire extinguishing device according to the invention, which is separated from the water tank.
- This can be grown outside at a suitable location to the water tank or housed in the interior.
- Both the interior of the water tank and the interior of the foam container can be pressurized with compressed gas from a compressed gas cylinder to expel the water or the foaming agent from the respective container.
- the outlet lines of the water tank and the foaming agent container lead into a mixing valve, which contains a manually adjustable valve element, by means of which the admixture of the foaming agent is switched into the water.
- the admixture of foam in the water is gradual or infinitely adjustable by a correspondingly adjustable valve element is provided.
- a so-developed extinguishing device can then be operated either as a pure water extinguisher or as a foam extinguisher.
- the compressed gas for Schaumverfest Trent be switched on.
- the introduction of the compressed gas can then take place either in the foaming agent prior to its introduction into the water outlet from the water tank, so that with the pressurized gas foaming agent is introduced into the water in the water outlet, or foaming agent and pressurized gas can at about the same point directly into the Water outlet be initiated.
- the extinguishing device according to the invention offers decisive advantages.
- the filled extinguisher can be used according to the conditions found by simply switching either as a pure water extinguisher or as a foam extinguisher, If the device is used as a foam extinguisher, by adjusting the Schaumsch- and compressed gas admixture to the water coming from the water tank the consistency of the foam can be adjusted in the entire area between heavy foam and compressed air foam. In addition, since the admixing rate of air can also be variably adjusted on the foam tube, the flake size and moisture of the foam can be adjusted within a wide range, and the expansion ratio is variably adjustable.
- the extinguisher can be designed as often in use and quickly refilled by the user refillable and thus further usable device by the water tank provided with a separate water filling opening with a tool-free detachable cap and the gas cylinder with a likewise by hand and without Tool operable quick coupling is connected to the container assembly.
- Fig. 1 shows a perspective view of the extinguisher in total with an extinguishing agent container 1, a coupled compressed gas cylinder 2 and a fire extinguisher 3, which is inserted into a holder attached to the extinguishing agent container 1 and is connected via an extinguishing agent hose 4 with the extinguishing agent container.
- Fig. 2 shows the extinguisher after Fig.1 in an exploded view, to make otherwise hidden components visible.
- the extinguishing agent container 1 has a top wall 11 and an upwardly projecting from this extinguishing agent filler neck 12, can be filled by the water and foaming agent in the extinguishing agent container 1.
- An attachable by means of a handwheel without tools and detachable cap 13 with a pressure relief valve 14 serves to close the filler neck 12th
- the compressed gas cylinder 2 with an openable by an overhead handwheel 21 outlet valve can be coupled via an operable with a handwheel 22, designed as a screw coupling quick coupling 23 to a pressure reducing valve 5, which is mounted on the top wall 11 of the extinguishing agent container 1 and above with a pressure gauge 51st is provided.
- a mixing valve block 6 is mounted on the top wall 11 of the extinguishing agent container 1. This contains a mixing valve for selectively mixing compressed gas into the extinguishing agent emerging from the extinguishing agent tank 1.
- the formed in the interior of the valve block 6, not visible in detail in the drawing valve is manually actuated by means of an actuator 61.
- a extinguishing agent outlet pipe 18 leads into the valve block 6.
- the extinguishing agent hose 4 which leads to the extinguishing pistol 3, can be coupled to the upper connecting piece 62 of the valve block in the drawing.
- a compressed gas line into the interior of the extinguishing agent container 1, through its top wall 11 therethrough to pressurize the extinguishing agent in extinguishing agent container 1 and to cause its extrusion through the extinguishing agent outlet pipe 18.
- a compressed gas line in the valve block 6 leads from the pressure reducing valve 5, a compressed gas line in the valve block 6 to the accommodated therein mixing valve, which is switchable by means of the actuator 61 between a closed and an open position.
- the valve is designed so that the opening cross section of the compressed gas line within the valve block is continuously adjustable between the closed position and the fully open position. The adjustment can also be done in stages. Thereby, the foam consolidation can be set as desired, namely switched on, switched off, and preferably regulated in their extent.
- Fig. 3 shows in exploded view the extinguishing pistol 3 (without connected extinguishing agent hose 4).
- This consists of a pistol part 31 with actuating handle 32, a coupling piece 33 which can be attached to the connecting piece 32, a foam tube 34 and a spray jet pipe 35.
- the foam tube 34 and the spray jet tube 35 are both fixedly mounted on the coupling piece 33.
- the coupling piece 33 has a pivoting part 36 which is detectable or detachable by means of a handwheel 37, and which allows a change of the respective effective tube, namely either the foam tube 34 or the spray jet tube 35 to the extinguishing gun 3.
- the foam tube has at its rear end a sleeve 38 which is provided at its periphery with a plurality of openings 39.
- the rear end of the foam tube 34 has the openings 39 of the sleeve 38 corresponding openings.
- the sleeve 38 is rotatable about a certain angle of rotation, which, as can be seen from the drawing, by a circumferentially extending slot 38a and a stop screw 38b, to the openings 39 of the sleeve 38 with the corresponding openings of the rear end of the jet pipe 34th between a position with full coverage and a position without overlap to move.
- the sleeve 38 By turning the sleeve 38 so the openings at the rear end of the foam tube 34 can be continuously closed or completely or partially opened to allow access of ambient air in the emerging through the foam tube foam and thereby further modify the foam consistency.
- the rotatable sleeve and an axially displaceable sleeve could be provided.
- Fig. 4 shows only a schematic representation of a development of the invention to the effect that the extinguishing agent container 1, a separate water tank 1 a and a separate foam agent container 1 b is provided.
- the foaming agent tank can be substantially smaller than the water tank 1a.
- the foaming agent container 1 b is formed so large that it can accommodate a multiple of the amount of foaming agent, which is needed for a complete filling of the water tank 1 a. Then, in use, the extinguisher, when the water is consumed, can be refilled with water and continue to operate as a foam extinguisher when the foaming agent supply reaches for several water fillings.
- the foaming agent container can either be arranged inside the water container, but of course be attached with its own filling opening, or at any convenient point outside the water tank, either laterally, or above or below the water tank then.
- the valve block 6 then contains both a manually operable mixing valve for introducing pressurized gas into the outlet line leading from the water tank 1 a to the valve block 6 18, as well as a manually operable admixing valve 6 b for mixing foam in the water in the outlet 18.
- the arrangement may be such that from the safety valve 5, a compressed gas line either directly into the Schaumffen inherenter 1b leads and there the foaming agent is also placed under Auspresstik as the water in the water tank la, or the mixing valve 6b for the foaming agent can with a (not shown) Compressed gas valve be combined, which simultaneously activates a pressurized gas line leading from the safety valve 5 via the valve block 6 to the foaming agent container 1b when adding Schaumffeneinspeisung in the extinguishing water, so that the foaming agent container is set only in the foam extinguishing operation under pressure.
- the admixing valve 6b for admixing foaming agent may be formed so that it is either only movable between an on and an off position, but preferably so that by stage or stepless adjustment also a regulation of the foam composition, ie the Schaumffenanteils in the water can be produced.
