Definitions
- the invention relates to a method for dispensing liquid media, in particular clearing liquids such as water or the like.
- m in the form of a mist or a coarse droplet from an open line, which is supplied with liquid from a supply line that can be switched on and off under low pressure, in rooms, for example living rooms and the like, for fighting fires after which the pressurized liquid is divided into partial streams after opening the supply line, the partial streams are set separately in rotation and then the rotating partial streams are brought together to form a spray cone.
- the invention further relates to a device for performing the above method with a basic body, on which a connection piece is provided for connection to an open line, which can be connected or disconnected via a closure member to a supply line stands, a Stromungskorper, which is traversed by a passage channel, a vortex chamber enclosing the Stromungskorper, wherein the passage channel is constant and the vortex chamber is occasionally flowed through by separate partial streams of the liquid
- EP 0 671 216 discloses a generic dry spray nozzle for generating spray mists using the low-pressure method, in particular for fire fighting with stationary water mist fire extinguishing systems.
- This known spray nozzle is installed radially in a pipeline of the fire-extinguishing system and consists of a housing with a flow body arranged therein, which is traversed by a conically tapering swirl mixing chamber. On the surface of this swirl mixing chamber there are helical swirl grooves with axial inlet openings which are connected to inlet openings for the water. Another flow of water enters an inner swirl mixing chamber through an annular space. There is a current distribution. One path leads via the inlet openings and the swirl channels to the cylindrical nozzle opening and creates an internal spray cone there. The second way leads via the annulus and tangential bores to an annular gap from which the water emerges as an outer spray cone.
- the invention has for its object to provide a method and a device of the type mentioned, with which it is possible, with approximately the same operating pressure of the extinguishing agent, one after the other in time, depending on the occurrence of the fire and the course of the fire, small droplet spray and coarse droplet spray while minimizing water consumption, reducing water damage in the event of a fire and increasing economic efficiency by implementing a modular system in any installation position.
- the invention is characterized above all by its simplicity and can be used particularly for drying systems.
- the invention enables simple quantity regulation in the divided and merged partial flows of the liquidity, a lasting influence on the vortex intensity depending on the occurrence and course of the fire.
- the device according to the invention first generates a spray-like droplet jet.
- the signal transmitter can be a smoke detector.
- a further particular advantage of the solution according to the invention is that the modular design of the base body and the variation of the flow bodies make it possible to implement a modular system which can be easily adapted to the different conditions of existing or also newly constructed fire extinguishing systems.

- the connector 1 is screwed to the middle of the cover plate 2.
- receiving spaces in the form of bores 8 are made for receiving one actuating device 9 each.
- the actuating device 9 consists of a sleeve-shaped hollow body 10, which is closed at both ends, an adjusting arm 11 which is operatively connected to the hollow body 10, and a locking mechanism 12 or adjusting mechanism 42 introduced (see Fig. 2).
- the hollow body 10 carries at its end facing the socket 1 a rotary shaft 16 in the form of a pin 17 which is guided to the outside through a bore 18 in the cover plate 2.
- the pin 17 is connected to the adjusting arm 11, which is fixed in its position by the locking mechanism 12.
- the distribution chamber 3 and the vortex chamber 5 are dimensioned in their height such that they correspond to the height of the slot opening 14 and 15 in the hollow body 10, respectively.
- the height of the intermediate plate 4 corresponds approximately to the distance between the slot openings 14 and 15 arranged one above the other.
- 3 shows the hollow body 10 in a perspective view the position of the slot openings 14 and 15.
- the hollow body 10 is closed with a plug-like insert 37, which on the inside is designed as a converter 38 with a curved surface.
- the pin 17 has a smaller diameter than the hollow body 10, so that the hollow body 10 has a shoulder 19 on which a sealing and bearing disk 20 rests, which bears the hollow body 10 seals and supports against the cover plate 2.
- the hollow body 10 thus penetrates the distribution chamber 3, the intermediate plate 4 and the vortex chamber 5 and is supported on a sealing and bearing disk 21 which lies in a recess machined in the outlet plate 6.
- a sealing and bearing disk 21 which lies in a recess machined in the outlet plate 6.
- the flow body 24 has a frustoconical head 27 with an outlet opening 28, which is also frustoconical on the inside.
- the head 27 of the flow body 24 projects into a funnel-shaped recess 29 of the outlet plate 6 which is oriented towards the swirl chamber 23 h and which merges into an outlet opening 30, which is followed by an outside outlet extension 31 with a tear-off edge 32 m of the outlet plate 6.
- the outlet extension can have a conical shape or some other suitable geometric shape.
- the water flowing in at the opening of the supply line through the nozzle 1 divides as shown in FIG Distribution chamber 22 in three substreams A, B and C.
- the two outer partial streams A and B pass through the free cross section of the slot openings 14 of both adjusting devices 9 with deflection m the hollow bodies 10, flow tangentially through the free cross section of the slot openings 15 into the swirl chamber 23, swirl there and then become in the channel-like flow funnel 33 merged.
- the two merged substreams emerge from the outlet opening 30 of the outlet plate 6.
- the third partial flow C enters the passage 25, is forced to rotate by the spiral 26, emerges from the opening 28 of the flow body head 27 and strikes the two combined partial flows A and B.
- the impingement of the rotating partial water flow C from the passage 25 enables a uniform distribution of the spray drops in the spray cone that is formed.
- the free passage cross section of the slot openings 14 and 15 changes, as a result of which the vortex intensity in the merged partial streams A, B and C can be set between minimum and maximum values (see FIG. 2).
- the setting angles ⁇ 1 and / or ⁇ 2 are changed by adjusting the setting device 9, the water flow speed in the slot openings 15 changes at constant water pressure.
- An increase in the setting angle ⁇ 1 or cc2 or both at the same time leads to a reduction in the slot opening 15 and accordingly to an increase in the flow rate and thus to an increase in the ability of the water to be atomized.
- a spray jet with a predominant proportion of fine drops is created, which is particularly suitable for combating a fire start phase.
- E ne reduction of the setting angle ⁇ l or ⁇ 2 or both at the same time leads to a reduction in
