Definitions

  • the invention relates to a device for delayed actuation of a valve, especially in connection with a fire extinguishing system, the delay time is adjustable by an electro-mechanically operated delay device, which consists of a motor-driven threaded spindle with a non-rotating one Threaded nut, with a, a bolt actuating driving pin, and the Delay device by means of a triggering device on an opening element of the Valve acts, the trigger device one of the delay device Lockable locking element is assigned that after the delay time is released and thus the opening element is actuated.
  • an electro-mechanically operated delay device which consists of a motor-driven threaded spindle with a non-rotating one Threaded nut, with a, a bolt actuating driving pin
  • the Delay device by means of a triggering device on an opening element of the Valve acts, the trigger device one of the delay device Lockable locking element is assigned that after the delay time is released and thus the opening element is actuated.
  • Such a device is known (DE 40 05 777 C1) and is in one Fire extinguishing system part of a fire alarm system.
  • the Safety for opening the valve in case of fire according to a prescribed Delay time increased many times over and the risk of accidental Tripping, resulting from inductances, lightning or the like, can be avoided.
  • the Safety is only guaranteed if the device is properly created and is properly installed.
  • the invention lies in ensuring these specifications the task of creating a device that can be produced in the workshop and can be assembled on site with the simplest of means.
  • the device can be expanded with the simplest means in such a way that a switch for actuation the motor, a switch to monitor the position of the threaded nut, and a Emergency switches are provided.
  • the essential features of the device 1 are the delay device 2 which Tripping device 3, the opening element 4 for the valve 7, the blocking element 5 and the force translator 6.
  • a housing 8 which has a cover 9 by means of cover fastenings 12 can be closed, the delay device 2 and the blocking element 5 accommodated.
  • a motor 14 is connected to the side wall 10 by means of a motor flange 15 of the housing 8 flanged.
  • the flange 15 and the side wall 10 are with holes 34 and 35 provided, through which a threaded spindle 16 is guided.
  • this is with connected to the motor 14 and on the other hand with a threaded nut 17 Provided threaded bore 20 and a driver pin 18.
  • In the side wall 36 of the Housing 8 has a recess 29 into which one end of a bolt 21 the delay device 2 is guided.
  • the latch 21 On the other end face of the latch 21 is a bore 26 is provided, in which a guide rod 27 is inserted, which in a Guide opening 28 of the side wall 10 is guided.
  • the latch 21 consists of a Latch body 22 with an angled stop on the lower surface 48 to which the Driving pin 18 of the threaded nut 17 can be attacked.
  • the bolt body 22 provided with an elongated hole 24 through which the bolt 30 is formed Locking element 5 can be passed.
  • One end of the bolt 30 is through an opening 37 out in the rear wall 11 of the housing 8.
  • the other end is with an enlarged bolt head 31 which is arranged so that it on a Inclined surface 25 of the surface 47 of the latch 21 abuts.
  • the bolt head 31 stored in a bearing opening 33 of a guide cam 32 of the cover 9.
  • the bolt 30 is still with a locking disk 38 and the driving pin 18 of the threaded nut 17 with a Recess 19 provided.
  • the recess 19 is in the standby state Device 1 is placed on the bolt 30, thereby preventing the locking element 5 unwanted unlocked the trigger device 3.
  • the delay device 2 is in the standby state and thus shown in the locked position.
  • the motor 14 is switched on Fire control panel, not shown, actuated so that now in the threaded bore 20 seated threaded spindle 16 drives the threaded nut 17 in the direction of the Motor 14 is moved. Due to the thread pitch of the threaded spindle 16 and The delay time can be set at their speed. After the delay time has expired the driver pin 18 reaches the stop 23 of the bolt 21 and moves it likewise in the direction of the motor 14. Because of the inclined surface 25 of the latch 21 the bolt head 31 of the locking element 5 held by a spring 39 in the direction pushed onto the lid 9.
  • the locking disk 38 can also be moved.
  • the locking element 5 is moved so far that the locking force on a lever 40 of Tripping device 3 is canceled.
  • a spring 41 under tension moves the lever 40 mounted on a shaft 42 upwards, so that the locking effect of the locking lever 43 on the spring 45 of the force booster 6 is lifted.
  • the actuating rod 44 of the opening element 4 in the direction of the Actuating lever 46 moves, which opens the valve 7 and thus the Deletion is initiated.
  • the trigger device 3 can be in a separate Housing 13 are housed, which in turn together with the housing 8 for the Delay device 2 can be connected to a compact unit.
  • the switch 60 gives the command to the motor 14 to switch it off, when the valve 7 is open.
  • the lever 40 is fixed to the shaft 42 so that after the release and pivoting of the lever 40, the shaft 42 also rotates.
  • the shaft 42 is passed through a bore 57 of the housing and carries one at the housing end Eccentric 58, which is associated with an operating lever 59 mounted in a bearing 67 and is arranged so that it can operate the contact 61 of the switch 60. Will the Unlocked lever 40 and thus the shaft 42 is pivoted with the eccentric 58, the Contact 61 released. Motor 14 now receives switch 60 the command to stop.
  • the device 1 is again in the standby position brought and the lever 40 is reset to the original position, the Eccentric 58 also brought back to the starting position and thus the contact 61 closed.
  • the motor 14 is actuated again and the threaded nut 17 in brought to their standby.
  • the switch 62 with its contact 63 is like this arranged that the contact 63 with the bevel 56 on the driver pin 18 Threaded nut 17 attacks. If the threaded nut 17 after turning on the Motor 14 moved out of the ready position, the contact 63 opens and shows so that the threaded nut 17 has been moved and no longer in Is on standby. The threaded nut 17 is again in the ready position driven, the contact 63 is closed and thereby the motor 14 via the switch 62 switched off again.
  • the switch 64 is provided as an emergency switch. It monitors the functionality of the Switch 60 or the functionality of the latch 21, e.g. if it sticks or other interferences occur.
  • the contact 65 lies on the surface of the recess 54 of the latch 21 and is actuated when the inclined surface 55 reaches the contact. It can thus the safe function of the bolt 21 for opening the valve 7, as well as for the provision is monitored in the event of renewed readiness.
