  • escape agents such as a combination of (E) -2-but
  • a dispensing device for liquids with the features mentioned in the preamble of claim 1 is made US 2002/0148908 A1 known.
  • the object of the present invention is to provide a dispensing device, with which as far as possible without the use of propellants or booster pump safety fluid can be applied and atomized with rapid evaporation with the lowest drop flight paths and can be quickly built with the required concentration of safety fluid.
  • the object is achieved by a dispensing device according to claim 1.
  • the safety liquid By the rotation of the atomizer wheel, the safety liquid is thrown away and a negative pressure is generated which releases the safety fluid from the safety fluid source, e.g. from a storage container, sucks.
  • Safety fluid source is connected to the atomizer wheel via a fluid channel in the valve and the valve has an air inlet channel which is sealed off from the fluid channel. Air can flow in through the air inlet channel to the safety fluid source and pressure equalization is made possible.
  • the safety liquid is accelerated by centrifugal force and introduced at high speed into the ambient atmosphere. This results in a rapid, uniform increase in the safety fluid concentration in the ambient atmosphere.
  • an impact surface is advantageously provided around the circumference of the atomizer, which is preferably inclined relative to the axis of rotation of the atomizer wheel.
  • This valve is a slide valve with a valve piston and a valve body which, in the closed state, closes the safety fluid outlet channel and the air inlet channel and in the opened state connects the safety fluid outlet channel with the atomizer wheel and connects the air inlet channel to the atmosphere.
  • the slide valve can be easily mechanically, electrically, electromechanically, pneumatically, hydraulically or pyrotechnically operated at high tightness.
  • a run-up element may be provided which cooperates with a ramp surface on the valve piston to move it upon rotation of the Zerstäuberrades.
  • the Zerstäuberrad contains a trigger element with claw function, which cooperates with an exemption on the valve piston to move it by rotation of the Zerstäuberrades by spring force.
  • the dispensing device comprises an electric motor for rotating the Zerstäuberrades.
  • the dispensing device according to the invention contains a safety fluid level monitoring device.
  • the safety fluid used is the extinguishing agent Novec TM 1230 from 3M TM.
  • a liquid solution of irritants such as oleoresin capsicum, escape agents such as a combination of (E) -2-butenylmercaptan (C4H7SH), 3-methylbutanethiol and the corresponding S-acetyl compounds, markers such as dyes and fluorescent pigments can be used as the safety fluid or a combination of the above are used.
  • escape agents such as a combination of (E) -2-butenylmercaptan (C4H7SH), 3-methylbutanethiol and the corresponding S-acetyl compounds
  • markers such as dyes and fluorescent pigments
  • the storage container 1 has the shape of a bottle having a safety fluid outlet opening 2 and a separate from the same air inlet tube 3.
  • the safety fluid outlet opening 2 and the air inlet pipe 3 open into separate holes 4, 5 in the valve housing 6, which is screwed onto the bottle neck.
  • a valve sleeve 7 is inserted, which is sealed at its tank-side end opposite the valve housing 6 and at its end facing away from the storage container 1 in a Zerstäuberrad 8 opens.
  • a valve piston 9 is slidably disposed, which has a central bore 10 into which a bore 4 for safety fluid in the valve housing 6 extending safety fluid tube 11 protrudes.
  • the axis 12 of the atomizer wheel 8 is driven by an electric motor 13.
  • a baffle 14 is provided, which is inclined relative to the longitudinal axis of the valve.
  • a level monitoring tube 32 is tightly attached to the safety fluid level monitoring on the valve housing 6, which has an upper and a lower float stop 30, 31 at the top, the valve housing 6 facing away from the end.
  • a reed contact 33 is mounted, which switches with the magnet 34 when the coaxial float 28 descends.
  • Fig.1 the safety fluid level 29 is shown above the safety fluid level monitoring device
  • Fig.2 represents a depleted storage container.
  • the valve designed as a slide valve by the electric motor 13 from its closed position ( Figure 3 ) in its open position ( Figure 4 ) are moved.
  • the electric motor 13 for example driven by a control unit, which has received a signal from a fire detection device, the atomizer 8 in rotation.
  • a radial pin 23 is provided, which serves as a run-up element for a ramp surface 24 on the valve piston 9.
  • the ramp surface 24 of the valve piston 9 runs at the rotation of the Zerstäuberrades 8 on the pin 23 and the valve piston 9 is moved in the direction of the storage container 1 relative to the valve sleeve 7 until it is in the open position ( Figure 4 ) is in which the lying on the circumference of the valve piston 9 O-rings 20 and 22 have no contact with the valve sleeve 7 and in which therefore the liquid channel 26 and the air inlet material channel 27 are continuous.
  • the safety fluid can therefore flow radially from the space 16 into the interior of the Zerstäuberrades 8 and from there through the Ausbringö réelleen 25 to the outside.
  • the centrifugal force generated by the rotation of Zerstäubungsrades 8 creates a negative pressure and sucks safety fluid from the storage container 1.
  • the emerging from the discharge openings 25 safety fluid is further atomized by the impact on the baffle 14. At the same time, air can flow in through the air inlet channel into the storage container 1.
  • the storage container 35 has the shape of a hollow cuboid, which is sealed by means of lid 36 and O-ring 37.
  • the safety fluid level monitoring is realized by a commercially available level sensor 68.
  • FIG 5 is the safety fluid level above the level sensor 68, in Figure 6 below.
  • the storage container has a safety fluid outlet opening 38 and an air inlet tube 39 separated from it.
  • the safety fluid outlet opening 38 opens into a central bore 40 of the valve piston 41, the air inlet tube 39 opens into a cavity 42 between the valve housing 43 and a pot 44.
  • the valve housing 43 is tightly screwed to the storage container 35, sealed by an O-ring 45 and opens the end facing away from the storage container 35 in a Zerstäuberrad 46.
  • a valve piston 41st arranged, which has a central bore 40, into which a safety liquid tube 47 extending the safety fluid outlet opening extends.
  • the axis 48 of the Zerstäuberrades 46 is driven by an electric motor 49.
  • a baffle 50 is provided, which is inclined with respect to the longitudinal axis of the valve.
  • the described path of the air passing through the arrow 58 in FIG Figure 8 is shown, forms the air inlet channel.
  • the liquid channel and the air inlet channel are separated from each other by the O-ring 69, so that in the case of application, the safety liquid can be removed from the storage container and at the same time the storage container can be vented so that the quantity of safety fluid per unit of time is kept approximately constant during the discharge of the safety fluid can.
  • the space 52 between the valve piston 41 and the valve housing 43 is closed by the O-rings 69 and 59 and communicates only with the radial bores 51, so that no safety fluid from the fluid channel Figure 8 can get into the interior 53 of the Zerstäuberrades 46.
  • the space 56 between the valve piston 41 and the valve housing 43 is closed by the O-rings 69 and 60 and only communicates with the air openings 55 in the valve housing 43, so that no air through the air inlet channel Figure 8 in the air inlet pipe 39 and thus can get into the storage container 35.
  • the position of the valve piston 41 with respect to the valve housing 43 ensures a permanently sealed closure of the storage container 35.
  • valve piston 41 in the valve designed as a slide valve by the electric motor 49 from its closed position ( Figure 5 and Figure 7 ) in its open position ( Fig. 6 and Figure 8 ) are moved.
  • the valve piston 41 In rest position ( Figure 7 ), the valve piston 41 is biased by a spring 61, which is supported on the one hand on the valve housing 43 and on the other hand, the valve piston 41 presses on the claw 62 on the overlapping oriented claws 63 of the atomizer wheel 46.
  • the electric motor 49 for example driven by a control unit, the atomizer 46 in rotation.
  • valve piston 41 is displaced by the spring 61 in the direction of the electric motor 49 relative to the valve housing 43 until the shoulder 64 abuts the support surface 65 of the support plate 66 and is thus in the open position ( Figure 8 ), in which lying on the circumference of the valve piston 41 O-rings 59 and 60 have no contact with the valve housing 43 and in which therefore the liquid passage and the air inlet passage are continuous.
  • the safety fluid can therefore flow radially from the space 52 into the interior of the Zerstäuberrades 46 and from there through the Ausbringö réelleen 67 to the outside.
  • the centrifugal force generated by the rotation of the Zerstäubungsrades 46 creates a negative pressure and sucks safety fluid from the storage container 35.
