Definitions

  • the invention relates to a fire protection shut-off device for ventilation ducts, Air outlets or the like ventilation equipment, with a Installation housing with valve seat arranged therein and a lower Federbeetzschung in open position held valve closing body, the predetermined temperature by the force of a closing spring in the closed position is fast or transferred, wherein the valve closing body one of the Closing spring surrounded valve stem is connected, in one with the Installation housing connected guide bush is guided, wherein the Valve rod is associated with a locking device, which the Valve rod and the valve stem in the closed position Valve lock body locked.
  • the closing spring is in such fire protection shut-off devices regularly between a fixed abutment and an arranged on the valve rod abutment with interposition a fusing solder holding the valve closing body in the open position biased.
  • Such fire protection shut-off devices are used ventilation ducts, Automatically close air outlets or the like in case of fire, so a passage of fire and smoke is prevented and located on the Fire-side do not develop flammable gases that spread over predetermined temperature can heat up to auto-ignition. For this reason, such fire protection shut-off must in Fire trap not only close properly, but it must also be ensured be that the valve closing body remains in its closed position.
  • These are Arretismesvorraumen provided which the valve rod and over the Lock the valve stem in the closed position valve closing body.
  • shut-off device for example Ventilation devices with a valve closing body, which under Spring loading is held in an open position.
  • the valve closing body can be in the Transfer closed position.

  • the invention teaches in a generic Fire protection shut-off device for ventilation ducts, air outlets or The like ventilation devices that the locking device to the Valve rod has connected spreading spring, which in the transition from the open position in the closed position against a locking seat on or in the guide bush spreads.
  • the locking seat is preferably as in the guide bush inside circumference arranged inner collar formed predetermined width.
  • the inner waistband can completely rotate on the inside and thus form an annular bearing surface. It can However, also be realized only partially circulating covenant. After all can also several, single Arret istsschultern or the like be provided. The z. B.
  • U-shaped spreading spring can be at least two in the Substantially axially parallel extending spring leg having, which Transition from the open position to the closed position radially are spread apart.
  • the ends of the spring legs are the Assigned locking seat. This means that the spring legs or their Ends in the closed position substantially, d. H. if necessary under consideration a montage employmenten game, abut against the locking seat.
  • the guide bush thus has a first inner diameter range below or behind the Arret istssitz on, at which the spring legs of the spreading spring in Open position. Above or before this first diameter range is then the second diameter range with increased inner diameter arranged. Between these areas is the z.
  • the spring legs of Spreading spring cylindrical shell-shaped or partially cylindrical shell-shaped This embodiment takes into account the fact that it is in the Valve rod surrounded closing spring regularly around a cylindrical Helical compression spring acts and also the guide bushing substantially cylindrical or hollow cylindrical shape.
  • By adapting the spring leg shape to the shape of the other components succeeds a particularly Space-saving design that ensures trouble-free operation.
  • the guide bush in predetermined distance to the locking seat inside a circumferential collar having predetermined width as an abutment for the closing spring. Because the Guide bush is firmly connected to the installation housing or else is formed integrally with this, this forms inside circumferential collar in the form of another annular surface a fixed abutment for the Closing spring.
  • a fusible link cap can be screwed on be, which has a fastened by means of fusible link lid.
  • the fusible link cap can be screwed onto the guide bushing or into the guide bush are screwed in. In this context it is expedient if the guide bush outside a first external thread and a second external thread.
  • the guide bush for example, on the installation housing or a corresponding holder attach the installation housing.
  • the fusible link cap are screwed on one of the External thread.
  • the two each End-side arranged external threads can have a different Have diameter. However, it can also be identical in diameter and also with a single, continuous external thread on the Guide bush to be worked.
  • valve rod end Pressure piece which in the closed position of the closing spring against the Schmelzlotkappe or their lid is pressed.
  • the closing spring pushed onto the valve rod and the Valve rod then inserted through the guide bushing. Subsequently can end connected to the valve stem of the valve closing body become.
  • the valve rod is so far in the Guide bush pressed that the valve closing body in the desired open position is located.
  • the closing spring between the Fixed abutment in the guide bush and the pressure piece on the Valve bar cocked.
  • a fire protection shut-off device for ventilation ducts or Air outlets shown in their basic structure on the one hand a mounting housing 1 of z. B. plastic with a arranged therein Valve seat 2 and on the other hand a spring loaded in the open position held valve closing body 3, which at a predetermined temperature is transferred by the force of a closing spring 4 in the closed position or in Closed position fast.
  • On the valve closing body 3 is one of the Closing spring 4 surrounded valve rod 5 connected, in one with the Installation housing 1 connected guide bush 6 is guided.
  • the guide bush 6 is formed as a separate component (made of metal) and in a holder H (plastic) of the mounting housing 1 attached.
  • the valve rod 5 is associated with a locking device 7, which the Valve rod 5 and the valve rod 5 in the closed position Valve closing body 3 locked.
  • This locking device 7 has a to the Valve rod 5 connected spreader 8 in the form of a spreading spring. 8 on, which at the transition from the open position to the closed position spreads, against a locking seat 9 in or on the Guide bush.
  • the locking seat 9 is in the embodiment as in the Guide bushing 6 arranged, inner peripheral side completely circumferential Inner collar 9 is formed.
  • This inner collar 9 forms a complete as it were circumferential locking shoulder or a locking seat in the form of an annular surface 9 predetermined width.
  • the expansion element 8 is designed as a spreading spring 8 made of metal.
