Definitions
- the present invention relates to a closure for sprinklers and nozzles with heat release according to the preamble of patent claim 1.
- the melting temperature of the melt release over the years can change.
- the temperature and its fluctuations in the monitored space plays a role. If the temperature rises above 30 ° C, it is possible that the material structure and thus the property of the melt release slowly and creeping changes. One can no longer be sure that the melting trigger actually melts at the intended temperature. The melting point may be higher so that it responds too late, but it may also be lower so that it responds too early. Both provide for damage that you actually wanted to avoid using such devices.
- WO 03/105963 A1 Another problem of the invention presented in WO 03/105963 A1 is the triggering room temperature. Basically, you want to use the effect of the sprinklers and nozzles where embers or fire occurs. But one is not sure if the highest temperature occurs just where the fire or embers would be extinguished. Sometimes a local fire triggers too much or the wrong sprinklers and / or nozzles, unnecessarily causing additional water damage. In many cases, the beginning of a fire is not at all recognizable by fire and the associated heat development, but by the smoke development. Where there is smoke there is fire, but the high temperature that triggers and triggers may not occur much later. This means that in many cases, the relatively late time at which the sprinklers and / or nozzles are used has already caused great damage.
- the present invention now has the object to improve a closure for sprinklers and nozzles with heat release of the type mentioned in such a way that an alarm triggering device first gives the alarm, but then automatically in the event of failure to ignore this alarm in deletion function.
- This object is achieved by a closure for sprinklers and nozzles with heat release with the features of claim 1. Further features of the invention will become apparent from the dependent claims and the advantages thereof are explained in the following description.
- the presented closure for sprinklers and nozzles with heat release is mainly used for nebulization nozzles, but can be used analogously for sprinklers use.
- the closure consists of a nozzle 1 with a nozzle body 2 which has an outlet opening 10 and an outlet channel 11, through which the extinguishing medium in the application with pressure and Flows out speed.
- the extinguishing medium is a liquid, it is divided into droplets or jets depending on pressure and velocity through the outlet channel 11 and the outlet opening 10.
- the size of the droplets produced in nozzles or the shape of the jets formed with sprinklers depend on pressure, speed and configuration of the outlet channel 11 and the outlet opening 10. It is crucial which extinguishing medium is selected and in which state this is to traverse the nozzle in the application.
- the shape of the outlet channel 11 and the outlet opening 10, is adapted to the existing pressure in the system and the desired for the deletion speed of the extinguishing medium.
- the small droplets generated in a nozzle create a spray that spreads throughout the volume of the sprayed space.
- direct liquid fitting is produced in the environment to which the sprinkler is directed.
- a cover plate 20 is fixedly connected to the nozzle body 2 by a melt trigger 5 via a ring 22.
- the melt trigger 5 may be a metal alloy, a plastic or a Be adhesive.
- the selected material must ensure the firm connection between ring 22 and cover plate 20 against the force F over years. Furthermore, the material must have a relatively narrow melting range that can be reliably defined for years.
- the connection between cover plate 20 and ring 22, which is ensured by the melt release 5, should not be in contact with the extinguishing medium, if it is a liquid. An influence such as the cooling effect on the melt trigger 5 by applied extinguishing medium would change its melting range.
- the sealing of the nozzle and the removal of the extinguishing medium from the melt trigger 5 is carried out by a structural part 21. This under tension standing construction part 21 simultaneously seals on the nozzle body 2, the outlet opening 10 and the outlet channel 11.
- the ring 22 is bolted to the nozzle body 2, for example.
- a heating element 23 may be integrated in the ring 22 (FIG. 1) or enveloped in the same (FIG. 2). It is also possible that ring 22 is not a separate part, but an annular elevation on the circumference of the nozzle body 2. The manufacturing technology and the manufacturing costs will be decisive for the type of construction you choose.
- the heating element 23 may be a resistance heater or an induction heater. It is important that the heating power of the same is sufficient to quickly melt the melt release 5 connecting the parts.
- the structural member 21 is a spring member which is clamped in the state of readiness under tension between the nozzle body 2 and the cover plate 20.
- the fusion initiator 5 serving as a connection must have sufficient bonding force to maintain the force F generated by the structural member 21 for years.
- the force F must be so great that the structural part 21 with the nozzle body 2 and, if it is an annular disc spring, with the cover plate 20 ensures a secure sealing line.
- connection force of the melt trigger 5 as an upper limit and a requirement for tightness and safe operation in the application of the structural part 21 as a minimum requirement for the force F.
- connection force of the melt trigger 5 as an upper limit
- a requirement for tightness and safe operation in the application of the structural part 21 as a minimum requirement for the force F.
- ring 22 is formed as a survey of the nozzle body 2, one would insert the whole unit of ring 22 (which is part of nozzle body 2), construction part 21 in a device, cover plate 20 and ring 22 with hot melt adhesive 5 and in the device with force lead together. In this state, the unit is heated to the extent that the hot melt adhesive 5 melts and connects with cover plate 20 and ring 22. After the entire unit is cooled, the hot melt adhesive 5 holds the unit together under the predetermined force.
- the firing or emergency triggering effect is not, as in conventional nozzles or sprinklers, generated by the known heat from the outside, but by targeted heating of the heating elements 23.
- This in turn has the advantage that in addition to the live structural member 21 also can still incorporate a heat deforming material.
- the construction part 21 could be made of bimetal, for example be made. The minimum required for sealing force with which the structural part 21 between cover plate 20 and nozzle body 2 must be clamped can be smaller. When the application occurs, first, the tension of the structural member 21 is increased by deforming the bimetal under heat. Then the melting of the melt release takes place, so that the cover plate 20 is separated from the ring 22 with considerable force and clears the way to the flow of the extinguishing agent through the outlet channel 11 and the outlet opening 10.
- the device presented here is suitable for use as autonomous fire monitoring with Themostat 30, smoke sensor 31, intelligent element (chip) 32 and an energy source (battery) 33. Especially in office, hotel and residential construction and in cases where the installation of a whole system and an entire system is not justified, such elements can be applied relatively easily.
- the device also works for gas extinguishing systems as they are used in computer rooms.
- Such autonomous misting nozzles 1 can be assembled together by combining the smart elements (chips) 32 of the individual nozzles with each other to form an entire system.
- devices can be installed there with thermostats 30, where you expect high temperatures in case of damage. If one expects especially with smoke, or wants to react to smoke, a smoke sensor can be installed. In an environment that can not be clearly assigned, one builds e.g. multi-criteria sensors.
- the intelligence of the system offers the possibility that a single autonomous device triggers an alarm first and reacts only after a defined time with extinguishing agent.
- a fire alarm triggers an alarm when poisonous smoke endangers people without immediately putting the whole extinguishing system into operation and thus Consequential damage.
- These intelligent systems serve as early warning systems for personal protection, while conventional sprinkler systems with simple glass barrel releases are only suitable for building protection.
- the generally valid regulations prescribe above all reaction in case of disaster. However, the claims go so far that one is warned long before the worst case occurs and can intervene.
- Such incrementally responsive systems react in a differentiated manner to suitably envisaged occurrence and avoid costly false alarms in fire and police.
- FIG. 3 shows a nozzle in whose design an energy source 33, sensors 30, 31 and chip 32 are introduced. Nozzle 1 and the intelligent elements 30,31,32,33 receiving ring 14 are placed on the ceiling 40. It corresponds in many cases to the desire of Interior design that no elevations affect the design of a ceiling. It is considered as a measure known to the person skilled in the art and therefore it is also possible without problems to install the entire unit in an opening in the ceiling or even in the ceiling, so that the presence of this fire protection device does not obviously come into the spotlight.
