Definitions

  • the invention relates to a transportable extinguishing gun, which has a quenching nozzle head, which is equipped at its front free end face with a plurality of spaced apart extinguishing nozzles, which are connectable to a supply line supplying extinguishing fluid and with which a fluid mist can be generated upon exposure to extinguishing fluid.
  • a fire extinguisher of the type mentioned in the introduction is known from US Pat. No. 3,704,831.
  • the nozzle head is rotatably arranged such that the nozzle openings arranged on the end face can be made to coincide by a rotation of the head with the outlet opening of an extinguishing fluid supply line. In this way, each one of the nozzles exits an extinguishing agent jet.
  • one of the extinguishing nozzles is designed such that it generates an extinguishing mist when exposed to extinguishing fluid.
  • the extinguishing fluid exits with a relatively high kinetic energy.
  • the advantage of using such an extinguishing fluid jet is that the extinguishing agent jet can be introduced into the area of the fire with a long range. In this way, among other things, the firefighter who operates the extinguishing system, exposed only a small risk of injury. In order to achieve this, in the past the water damage caused by the always required large amount of extinguishing agent to extinguish a fire has been accepted as inevitable.
  • a quenching nozzle head for stationary extinguishing systems which also has at its front, free end face a plurality of extinguishing nozzles.
  • Each of these extinguishing nozzles generates an extinguishing mist when exposed to extinguishing fluid taken from a pressure accumulator.
  • a central nozzle of the extinguishing nozzle head alone or all nozzles of the extinguishing nozzle head are acted upon together with fluid.
  • a piston which shuts off the flow to the extinguishing nozzles arranged laterally of the central nozzle when the pressure in the supply line drops below a minimum value.
  • extinguishing fluid can be discharged from the extinguishing nozzle head when the pressure discharged from the accumulator pressure drops so far that at full opening all extinguishing nozzles proper generation of the extinguishing mist would no longer be guaranteed.
  • the operation of the extinguishing nozzle head is firmly coupled to the pressure curve in the supply line, it can not be guaranteed when using such a nozzle that at all times the optimum for fighting a fire extinguishing mist is available.
  • the object of the invention is to improve a fire extinguisher of the type mentioned in that it reduces the amount of fluid required to extinguish a fire at an increased efficiency of the fluid mist.
  • extinguishing nozzles instead of or in addition to a central main nozzle to provide more extinguishing nozzles, which produce a finely dispersed extinguishing mist,
  • the individual extinguishing nozzles each of which, depending on the application, for example, fog of other nature and composition can produce their number, their respective Operation, the nature of their exposure to extinguishing fluid and their positioning on the extinguishing nozzle head, it is possible to produce a Löschnebel of special quality.
  • This extinguishing mist is optimally composed, inter alia, with regard to the nature and size of the individual mist droplets contained in it.
  • the extinguishing pistol according to the invention makes it possible, during the firing order, to adapt the type and composition of the generated extinguishing mist to the requirements which change as extinguishing success progresses.
  • a valve combination optionally one of the extinguishing nozzles for themselves and / or groups of extinguishing nozzles are acted upon with extinguishing fluid.
  • different extinguishing nozzle combinations can be used to produce a composite with a wide range of different fluid droplets Löschnebel.
  • the individual extinguishing nozzles can be arranged in a line next to each other. This can be beneficial for those cases where a uniform extinguishing mist outlet is desired over a large area.
  • the nozzles can also be arranged on the circumferential line of a circular arc or on a closed circle.
  • An advantageous with regard to easy maintainability of the extinguishing gun embodiment is characterized in that the extinguishing nozzle head is releasably secured to a support unit.
  • the rapid distribution of the extinguishing mist in the largest possible space can be facilitated by the fact that at least a certain number of extinguishing nozzles are arranged on an obliquely backward receding surface portion of the front end face of the extinguishing nozzle head.
  • the speed with which a volume of space can be filled can be further increased by the fact that the extinguishing nozzle head has a side surface on which at least one extinguishing nozzle is additionally arranged.
  • the portable extinguishing pistol shown in Fig. 2 has a quenching nozzle head 1, which is constructed rotationally symmetrical and on whose end face S an end face 2 is formed. In the center of the end face 2, a recess 3 is formed, which receives a central extinguishing nozzle 4.
  • the central extinguishing nozzle 4 is screwed into a screw receptacle 5 of a support unit 6, which is connected to a first supply line 7 and fixed to the housing tube R of the portable fire extinguisher L.
  • a circumferential surface section 8 which is conical and recedes at an angle ⁇ with respect to the front end face 2.
  • extinguishing nozzles 9 are arranged, which are connected to a second supply line 10.
  • the extinguishing nozzles 9 are arranged at regular angular intervals ⁇ to each other on a circle K, which is aligned concentrically with the opening 4a of the central extinguishing nozzle 4.
  • the extinguishing nozzles 9 Upon pressurization of the supply line 10, the extinguishing nozzles 9 generate an extinguishing mist, in which the individual liquid droplets have a low volume and emerge finely distributed from the nozzle openings 9a of the extinguishing nozzles 9 in the environment of a fire.
  • the extinguishing nozzles 9 In order to enable a replacement of the extinguishing nozzles 9 in a simple manner, they are screwed detachably into screw receptacles 11, which are connected to the second supply line 10.
  • a radially encircling side surface 12 connects.
  • the side surface 12 are at regular angular intervals ⁇ spaced apart further extinguishing nozzles 13 are arranged, which can be acted upon by a third, not shown supply line with pressure.
  • the extinguishing nozzle heads 13 are also located in screw receptacles 14 releasably and can be easily replaced when worn.
  • the extinguishing nozzles 9 can be acted upon jointly as a group with extinguishing fluid via the second supply line 10.
  • the extinguishing nozzles 13 are acted as a group together on the third, not shown supply line with extinguishing fluid. This makes it possible to independently apply extinguishing fluid to the central extinguishing nozzle 4, the group formed by the extinguishing nozzles 9, and the group formed by the extinguishing nozzles 13, respectively.
  • valve combination V Via an intermediate disc 20 provided with oblique bores, the outlet channels of the valve combination V associated with the two supply lines 7, 10 and the third supply line (not shown) are connected to the supply lines 7, 10 and the third supply line (not shown).
  • the washer 20 By using the washer 20, it is possible to design the valve housing of the valve combination simple and at the same time to choose the arrangement of the supply line 7,10 and the third supply line so that they occupy as small a space as possible.
