Definitions

the invention relates to a thermal triggering element for sprinklers, valves or the like in the form of a filled in a completely enclosed interior with an explosive vessel.
Such glass kegs as a thermal tripping element are for example in the DE 36 01 203 A1 described.
Such triggering element are filled with an explosive liquid, which expands when heated and leads to bursting of the typically clamped in a valve seat, the valve in the closed position holding vessel, so that a triggering of the valve or the like.
the explosive liquid on the one hand permit a highly temperature-sensitive and temperature-sensitive release of the triggering element equipped therewith and on the other hand bring with respect to the prior art reduced health hazards and environmental hazards and so make the processing less dangerous.
the groups include aliphatic bromides, hydrocarbons having a nitro group, monohalogenated benzene rings and aliphatic ester compounds each having two doubly bonded oxygen atoms.
aliphatic bromides may be those which are double-halogenated.
Nitro compounds have a high voltage coefficient and a high thermal conductivity due to their NO 2 structure. In addition, they have a low dynamic viscosity, whereby the small density and the higher heat capacity, which is otherwise disadvantageous in terms of the tripping time, can be compensated. Thus, even such substances lead to fast tripping times and also allow the choice of narrow temperature fields.
Cyclic molecules which already have good properties as an explosive liquid anyway, have high voltage coefficients and a low heat capacity as benzene rings with at most one halogen, which again leads to fast triggering times and narrow temperature fields.
aliphatic ester compounds with two doubly bound oxygen atoms in turn allow very narrow temperature fields and, although not to the same extent as the aforementioned substance groups, still have good release times. Due to the high boiling point, they are particularly suitable for use in high-temperature thermal tripping elements.
the triggering properties of the thermal tripping elements can be determined in a controlled manner, that is, they can be designed.
the explosive liquid may be added with advantage additives, in particular one or more dye (s). Since most of the selected triggering liquids are colorless transparent, the addition of a dye not only in the quality control facilitates, for example, recognizing a gas bubble deliberately left in the interior and estimating the size thereof, but by adding different dyes as in the prior art known and already used codes for different triggering temperatures are indexed.
advantage additives in particular one or more dye (s). Since most of the selected triggering liquids are colorless transparent, the addition of a dye not only in the quality control facilitates, for example, recognizing a gas bubble deliberately left in the interior and estimating the size thereof, but by adding different dyes as in the prior art known and already used codes for different triggering temperatures are indexed.
Fig. 1 in the schematically clamped between two bearing elements, a trigger element is shown, which is filled in accordance with the invention with a described and claimed explosive liquid.
the triggering element shown is a glass keg 1, as it is known in principle from the prior art.
the glass keg shown here essentially corresponds in its design to that in the DE 36 01 203 described form and expression.
the glass keg encloses a hollow interior 2 completely and lies in its use as a trigger element with opposite ends 3 and 4 on bearing elements 5 and 6, is clamped between them.
one of the bearing elements for example, the bearing element 5 is a valve plate of a sprinkler, the other layer element, such as the bearing element 6, a bearing bracket opposite this, as is often encountered in sprinkler systems.
the glass keg 1 can also be integrated as a thermal triggering element in an emergency discharge valve of a gas container or in similar devices.
the essential feature of the invention is now the explosive liquid introduced into the interior space 2, which leads to a bursting of the glass cask 1 and thus to triggering of the thermal release device when heated due to the thermal expansion.
the triggering liquid is filled while leaving a defined gas bubble (usually air) filled in the interior, the gas bubbles catching the first thermal expansion of the triggering liquid, until in particular by a phase transition is an explosive expansion, which bursts the glass keg 1.
the triggering liquid contains in the interior of the interior 2 at least one hydrocarbon, consisting of an aliphatic bromide, preferably a di-halogenated aliphatic bromide, a hydrocarbon having a nitro group, a monohalogenated benzene rings and an aliphatic ester compound with two double-bonded oxygen atoms or a mix of different Hydrocarbons from one or more of these groups.
the explosive liquid can only contain these hydrocarbons, but in particular consists entirely of one or more of the hydrocarbons mentioned.
additives can be added to the explosive liquid, in particular one or more dyes. Since most of the selected tripping liquids are colorless transparent, the addition of a dye not only facilitates recognition of the desired gas bubble in the quality control and estimation of its size, but by the addition of different dyes, the codes known in the art and already used for different trigger temperatures are indicated.
