Definitions

  • the invention relates to a thermal tripping element for a thermally controlled switching element having the features of the preamble of claim 1.
  • thermal tripping elements in the form of glass vessels, glass flasks or glass vials have long been known and are widely used in different fields of application. They are used to trigger temperature-controlled valves (as a form of a thermally controlled switching element) and are clamped for this purpose usually between a valve closure body and an abutment in its longitudinal course and acted upon in the longitudinal direction with a certain closing force. If the ambient air now heats up above a triggering temperature, this leads to an expansion of the triggering liquid in the interior of the glass bottle and, in the case of a force exceeding the resistance of the glass material due to the pressure of the expanding triggering liquid, the glass bottle breaks, so that the valve closure body is released and the valve opens.
  • temperature-controlled valves as a form of a thermally controlled switching element
  • a corresponding valve may be, for example, a shut-off valve in a sprinkler system, such as is used for fire protection reasons in buildings.
  • the valve can also be a safety valve of a gas container, which should open in case of fire, to blow off the gas contained in the gas container controlled and thus to prevent bursting of the container and thus an explosion.
  • the thermally controlled switching element for example, but also be an electrical switch, which is held by the thermal release element and against a switching force in an open or closed position and after triggering of the thermal release element by the switching force (eg exerted by a spring) is transferred to the other position.
  • thermal tripping elements in the form of elongated glass bottles are in different design variants, for example in the EP 0 215 331 B1 shown and described. Also shown is how this glass keg is clamped between two abutments.
  • a thermal tripping element with the features of the preamble of claim 1 is also known from DE 2118790 known.
  • a thin sealing layer is applied to the first end with the tip, which should consist of a plastic, eg Teflon.
  • thermal tripping elements are in the publications GB 409,569 and US 4,217,961 specified.
  • EP 0 244 746 For example, a method for treating a glass vessel, in particular a glass ampoule, and such a vessel itself are described, wherein the glass vessel disclosed therein is not that intended for use as a thermal triggering element.
  • the switching elements are preassembled, wherein the glass keg is clamped in a position between a movable switching means, such as a closure body of a valve, and the abutment by a deliverable to the switching means of the switching element, typically screwed abutment screwed against one of the longitudinal ends of the glass cask is until reaching a predetermined load or clamping force.
  • the screwable against the end of the glass cask element of the abutment is usually made of metal, often made of brass.
  • the torsion applied here is the greater, the larger the coefficient of friction between the material of the screwed abutment element and the material of the glass bottle is. This coefficient of friction is comparatively high between the materials typically used, glass and metal, usually brass.
  • the essential idea according to the invention consists in subjecting a per se known thermal tripping element according to the features of the preamble of claim 1 to at least the second longitudinal end opposite the end of the tip or at both longitudinal ends of a friction-reducing treatment, eg by application may be a adhering to the glass bottle coating, but also in a mere surface treatment such as fire polishing.
  • the thermal triggering element is thus formed in the form of a glass bottle, which has a rounded end at a second of its two longitudinal ends, on which the friction-reducing treatment is performed.
  • This friction-reducing treatment for example the application of the coating, accordingly no longer takes place in connection with the assembly process, but takes place in particular immediately after the production process of the thermal release elements (glass vessels) before they are packed and ready for further processing, in particular for pre-assembly of the Valve to be shipped. Accordingly, certain requirements must be imposed on the friction-reducing treatment: the result of this treatment must in any case be durable, and in particular an applied coating must adhere so well to the glass keg that it resists further handling of the glass keg in the course of application of the coating. in particular a packing operation, unpacking and transport until insertion into the valve between the closure body and the abutment.
  • the thermal tripping element is typically produced in a first production facility, provided there with the friction-reducing treatment and then packaged and then delivered.
  • a thermal triggering element can now be integrated directly into the thermal switching element without the previously required introduction of grease or oil, ie between the switching means, eg the closure body a valve, and the abutment are clamped by screwing an abutment element and thus applying a clamping force on the thermal release element.
  • the torsion element is here reduced at least by a value corresponding to the known method of greasing in the assembly process (reductions of about 30% are typically achieved), preferably even more.
  • thermal tripping elements reductions of the torsion element could be detected by friction reduction in a range between 30% up to 90%, depending on the selected treatment method, when coating also the coating material used.
  • coatings have emerged from eg wax, paints, and films.
  • the glass keg has a circumferential thickening at a first longitudinal end and the tip resulting therefrom, and at its second longitudinal end has the rounded, bulbous finish, the friction reducing treatment preferably being limited to the rounded, bulbous finish only there is, for example a coating is only applied there.
  • a thermal tripping element namely with the pointed end, which is generated when closing the space filled with the tripping liquid, is advanced against the switching means of the thermal switching element, e.g. against the closure body of a valve, set (often with the interposition of a spring element for receiving the closing force), and it is screwed the abutment against the bulbous end of the thermal tripping element.
  • the invention is not limited to an implementation in connection with glass kegs of the special geometry described here, but can also be applied to glass kegs formed throughout with the same diameter (without thickenings).
  • the second longitudinal end is preferably treated exclusively friction reducing, e.g. coated or surface treated, such as fire polished, which is the longitudinal end which, when installed in a thermal switching element, e.g. a trigger valve, abuts an abutment portion.
  • a thermal tripping member according to the present invention can be obtained by, after the manufacture of the thermal tripping element in the form of an elongated glass jar with a fully enclosed interior filled with a tripping liquid including a gas bubble, this glass jar with one of its longitudinal ends in a liquefied coating material dipped and so coated at this longitudinal end.
  • a thermal tripping member for example, ready-made glass bottles can be clamped in a device and immersed batchwise with the area selected for coating in a corresponding dip, pulled out with adhering coating material from the dip and for solidification of the coating, which is preferably present in a solid phase, are cooled.
  • thermal tripping elements in the usual way further processed, in particular packed for shipping and shipped to the assembly of thermal switching elements and unpacked and used.
  • a glass keg can be surface-treated, eg, fire-polished, eg, prior to filling with the triggering liquid and closing for the filling of an open end, ie as a semi-finished product, at the already closed end in order to reduce the coefficient of friction.
  • such a treatment can also be done on a completely filled and sealed glass kegs, if it is not the same triggering temperature is exceeded.
  • residues of a coating adhering to the thermal switching element after assembly may be removed from the thermal tripping element, e.g. by heating below the initiation temperature to melt and drain material of a correspondingly low melting point.
  • a coating adhering to the thermal switching element after assembly may be removed from the thermal tripping element, e.g. by heating below the initiation temperature to melt and drain material of a correspondingly low melting point.
  • such a procedure is usually not required, since the coating in the inventive manner preferably strongly limited locally and only in the region of the thermal release element, to which the element of the abutment to be screwed actually abuts and transmitted to the torsional force or a torsional moment becomes.
  • a thermal tripping element according to the invention in the form of a glass bottle 1 is shown schematically, wherein this glass keg 1 in the Fig. 1 in an arrangement position between a closure body V of a valve and an abutment W is shown.
  • Fig. 2 is the glass keg 1 completely in an arrangement in a valve, shown here in a sprinkler valve S.
  • the glass keg 1 has an elongate shape and encloses in its interior (not shown here) an elongated cavity which extends substantially over the entire length of the glass cask 1 and is filled with a triggering liquid and in which a gas bubble is contained in addition to the triggering liquid ,
  • the composition of the triggering liquid, its amount, the size of the glass vesicle and the wall thickness of the glass vial 1 determine the factors that are important for the thermal tripping element, such as the triggering temperature and the triggering speed (delay), ie the rate of reaction to an increase in temperature in the environment.
  • the glass keg 1 has at a first longitudinal end 2 a circumferential, shoulder-like thickening 3, from which a pointed end 4 extends out. This pointed end 4 is formed when closing the glass bottle 1 after filling with the triggering liquid by fusing.
  • the glass keg 1 At its second longitudinal end 5, which is opposite the first longitudinal end 2, the glass keg 1 has a likewise thickened bulbous termination 6. At this longitudinal end 5, more precisely in the region of the bulbous close 6, the glass keg 1 is provided in accordance with the invention with a coating 7 indicated here by hatching, which consists of a friction-reducing material in the solid phase.
  • a suitable application method is used, eg dipping, gluing, spraying.
  • this coating consists of a wax, a paint, a film.
  • a surface treatment for reducing friction can also be carried out in the area 7, eg fire polishing.
  • FIG. 1 schematically shows how in an installed state, the glass keg 1 is clamped in a valve between a closure body V and an abutment W in its longitudinal direction, in which example the glass keg is fixed with its first longitudinal end 2 on the closure body V by the pointed end protrudes into a blind hole B and the glass kegs with the thickening 3 rests on the edge of the blind hole B, and rests with its second longitudinal end 5, more precisely with the bulbous termination 6 at another blind hole BS in the abutment.
  • the coating 7 on the glass keg 1 is designed so that it covers the area in which the glass keg 1 rests with its bulge 6 on the portion surrounding the mouth of the blind hole BS in the abutment W.
  • the abutment W which is substantially cylindrically shaped and has a thread G on its lateral surface, is screwed into a corresponding mating thread and screwed in the longitudinal direction of the glass cask 1 for clamping it , the abutment W over the bulbous end 6 of the glass bottle 1 slides away due to the applied there friction-reducing coating 7.
  • Fig. 2 is again shown for clarity, as the glass keg 1 is inserted into a sprinkler valve S.
  • the closure body V serves here for closing a water channel K, in which in the use of the sprinkler valve S water is on which a discharge pressure is applied.
  • the closure body V is sealingly connected to a spring F, which in turn rests sealingly on a shoulder on the outlet side of the water channel K.
  • This spring F is used to record the closing force with which the glass keg 1 in the as in Fig. 2 It also allows the compensation of temperature variations caused by changes in length of the glass bottle 1 and the closure body V and the abutment W make.
  • the sprinkler valve S is provided with holding struts H, which form between them a dome-like opening in which the glass keg 1 is inserted.
  • the holding struts H open into a threaded opening O, in which the abutment W is screwed with its external thread and thus can be delivered in the longitudinal direction of the glass cask 1 on this.
  • a distributor star St Around the threaded opening O around a distributor star St is arranged, which fanned in the event of triggering the emerging from the water channel K water in a known manner, so as to achieve a broad surface effect for the fire extinguishing.
  • Fig. 2 shown application of a glass bottle 1 according to the invention for a sprinkler valve S is not the only possible application.
  • the glass keg 1 can be used, for example, also in thermally releasing relief valves on compressed gas containers or in comparable applications in which it depends on a thermally controlled release of a valve.
