Definitions
- the invention relates to a spray nozzle according to the preamble of claim 1.
- Spray nozzles and sprinklers for fire extinguishers are known in a wide variety of configurations. You point all on a valve body, which has a holder with the help of a thermal release element, preferably a glass barrel, is held in the closed position. Of the Pressure of the extinguishing liquid is present on the valve body. When the security event occurs, i.e. if the temperature increases so that the thermal release element is destroyed, it must be ensured that the holder holds the valve body releases so that the extinguishing liquid reach the source of the fire can.
- a thermal release element preferably a glass barrel
- the invention is based on the object of a spray nozzle to create according to the preamble of claim 1 is simple and small, especially a small one Has overall height and can be manufactured inexpensively.
- the spray nozzle is advantageously designed such that as stated in claim 2.
- the holder has one laterally protruding lever arm, which is the one bearing for forms the thermal release element.
- the other camp is the bearing lever, but also at a distance from the protruding one Lever arm is attached to the nozzle body.
- the Holder with the protruding lever arm is like a Bottle cap opener in the nozzle body in the area of the valve seat so hooked that in the event of a fire, i.e. then if that thermal release element is destroyed, this connection is reliably released so that the valve body the valve seat can leave.
- Characterized in that the thermal release element laterally essentially parallel to the longitudinal extent of the nozzle body is arranged next to this is the Height small. The holder can be easily and as a bent part be manufactured inexpensively.
- the spray nozzle is designed as in claim 2 is specified, then not only the thermal release element held securely, but it's also an easy assembly of the thermal release element possible.
- the spring travel of the lever arm is used, around the thermal release element, for example a glass barrel, to position in place.
- the device is designed as in claim 3 specified, then it is ensured that the overlapping Holders with lever arm do not move laterally can. So the lever arm is held once by that he form-fit the parallel sides of the nozzle head hook-shaped surrounds and the other in the incision lies in the end face of the nozzle body.
- the groove according to claim 4 serves the safe and immovable Arrangement of the bearing lever, the protruding lever arm lies opposite and between the and the lever arm thermal trigger element is arranged.
- the spray nozzle shown in the drawing consists of a Base body 1, which is installed as it is in the Drawing is shown, i.e. the one with the container for the Extinguishing liquid connected bore 16 is at the top.
- a conical and circular Valve seat 7 is provided, the valve body 3 in the form picks up a bullet.
- a swirl insert 2 Located just in front of the valve seat a swirl insert 2 in the direction of flow.
- the valve body 3 is held by a holder 5 which made of spring steel as it is from the drawing results. It has two lever arms 13 and 14. The one lever arm 14 is hooked into the nozzle body at 15. It stops the valve body 3 on the seat. The other lever arm 13 is resilient with respect to the lever arm 14 and protrudes laterally. It has an opening 11 for receiving the thermal release element on.
- the other end of the thermal release element is in an opening 12 in a bearing lever 4, which is also a Stamped part is and fastened in a groove 9 in the base body 1 is.
- the bearing lever 4 has two screens 10 for protection the tip of the thermal release element 6, which in this Trap is a glass vial, on.
- an incision 8 is provided, which the Storage and guidance of the lever arm 14 in this plane serves.
- the lever arm 14 and so that the holder 5 through this incision at a shift hindered. A corresponding one is made across the drawing level Movement prevented by hooking at 15.
- thermal release element 6 with its longitudinal axis substantially parallel to the longitudinal axis of the base body 1, but lies next to this. This creates a low overall height, and the individual Components are simple and inexpensive to manufacture.
- asymmetrical storage together with the spring action of the holder, i.e. the preload ensures that the parts that are triggered when a In the event of a fire, must be safely removed become.
