Definitions

  • the invention relates to a volume flow controller, in particular for air conditioning systems, with one in one duct around a transverse to the direction of flow of a gas Axle pivotable throttle element, the throttle element under the influence of the inflowing gas from the Open position is pivoted into the closed position and with decreasing volume flow back into the open position swings back.
  • volume flow controllers are available in different versions known. They work mechanically automatically.
  • Throttle elements can be throttle valves or sliding elements be provided.
  • a throttle valve is provided which is transverse to the Flow direction of the gas running in the middle of the Channel arranged axis is pivotable. On which the Axle opposite end of the throttle valve is one circular angle. This angle is used for Sealing from one to the middle of the channel protruding stationary duct sheet.
  • the throttle valve divides the channel in the direction of flow such that on one side of the throttle valve a storage space is formed and on the other side the Gas outlet opening is. At low pressure the inflowing Gases is the throttle valve with the angle in the storage space. Once the difference between the total pressure and the static pressure in the storage space is greater than is the static pressure in the gas outlet opening, the Throttle valve pivoted into the gas outlet opening at the angle, so that the flow is reduced or interrupted becomes.
  • the disadvantage is that due to the arrangement of the throttle valve only a small flow cross-section in the open position related to the channel cross section in Flow direction seen in front of the volume flow controller Available.
  • such throttle valves are subject increased wear and tear because of the throttle valve even a torque works.
  • the object of the invention is therefore a volume flow controller specify the maximum available outlet cross section in the area of the throttle element essentially the channel cross-section seen in the flow direction before Volume flow controller corresponds and in addition constructively is simply constructed.
  • the throttle element from a cylinder jacket shaped on at least one rotating leg trained wing whose radius is in corresponds approximately to the length of the rotating leg, where at least one surface element is provided on the rotating leg is, and that the axis of the swivel leg in little Distance to a wall of the channel is arranged.
  • the wing is approximately parallel to the open position to a wall of the canal so that the maximum is available standing outlet cross-section in the area of the wing not significantly smaller than the cross section of the channel before the volume flow controller.
  • the wing itself is subject to almost no wear, because of the radial Arrangement of the wing around the axis no torque the wing itself works.
  • the wing is driven through the surface element (s).
  • Each surface element can e.g. B. as Baffle plate be formed.
  • CH-A-325 380 is a volume flow controller known with the features of the preamble of claim 1.
  • the setting of a setpoint at which the volume flow controller interrupts the flow of the gas by means of the wing can by the number of surface elements be determined. With increasing number of surface elements the available flow cross section in the Range of the volume flow controller is reduced so that the Wing that is flown by the gas against the surface element (s) is driven, the flow of gas reduced or interrupted even with low volume flows.
  • the / the turn leg can either on the volume flow face of the wing or about be integrally formed on the wing.
  • a baffle bar to finish the wall of the channel to the wing forming a slight Gap is arranged and designed accordingly.
  • Each surface element can on the rotating legs z. B. molded or be screwed on. But with that the number of Surface elements can be changed easily and quickly, lends itself when the surface element (s) are created using a clip or snap connection is (are) attached. This makes it easy to loosen and fasten the surface elements possible.
  • a flow cross-section reducing element be provided in the area of the wall of the channel where the wing is at completely closed position.
  • the Flow cross section reduction element becomes the flow cross section reduced in the area of the volume flow controller, and the wing is earlier in the closed position on the wall.
  • the flow cross section reduction element can expediently as a cross-flow direction especially adjustable baffle be formed, the inclination of the guide plate preferably is adjustable from outside the channel.
  • the flow cross section reduction element integral part the wall of the canal. In this case, the corresponding Simply bevel the wall.
  • the rotating leg (s) can a damper, especially vibration damper equipped his. Damping can be done either by friction, where, for example, two solids by direct Contact each other, or by hydraulic or pneumatic effects are brought about. But also one magnetic non-contact damping is possible. For this is, for example, on the rotary leg (s) corresponding the pivoting deflected itself through a Magnetic field of a magnet moving metallic damping element intended. When moving in the damping element generates a current, and a magnetic field in the Damping element induced. This in the damping element induced magnetic field interacts with the Magnetic field of the magnet, both magnetic fields now tighten so that the vibrations are dampened.
  • Fig. 1 shows a volume flow controller 1, which in a not shown air conditioning system such. B. Air conditioning is installed.
  • the volume flow controller 1 exists from walls 2 that form a channel.
  • In the volume flow controller 1 there are two rotating legs 3, which with their one end are rotatably supported about an axis 4.
  • the Axis 4 is at a short distance from that in this figure Wall 2 of the volume flow controller 1 shown above arranged.
  • a wing 5 is formed as a throttle element is shaped like a cylinder jacket.
  • the exemplary embodiment shown are the rotary legs 3 on the end facing the flow (a) of a gas of the wing 5 molded.
  • the radius of the wing 5 corresponds approximately to the length of the rotating leg 3.
  • a baffle bar 6 integrally formed on the wall 2 of the volume flow controller shown in FIG. 1 below 1 is on the side facing away from the flow (a) of the gas Side of the rotating leg 3, a baffle bar 6 integrally formed.
  • the height and orientation of the storage bar 6 is so chosen that between the wing 5 and the top of the Ram bar 6 a little during the entire swivel path Gap 7 remains.
  • the number of surface elements can be used to set the setpoint 8, for example glued or screwed can be varied. But there are also rest or Clip connections possible.
  • a complete closure by the wing 5 is not possible because the wing 5 can only pivot as long a flow between the wing 5 and the wall 2 prevails. If it was closed completely, the pressure would be on both sides of the surface elements 8 the same. In this The case would be no pressure difference across the surface elements 8 to drive the wing 5 available.
  • Fig. 3 shows another embodiment in which a Ram bar 6 is not required because the wing 5 against the flow direction (a) has been extended. Swings the Wing 5 in the position shown in dashed lines, so causes the one provided on the upstream side of the rotating leg 3 Adequate sealing area of the wing 5 compared to the lower wall 2 in this figure.
  • Flow cross-section reducing element 10 is provided, that the swivel path of the wing 5 in the direction of arrow 9 limited. In the illustrated embodiment, this is Flow cross section reduction element 10 as a baffle 11 formed in the inclination in the direction of the arrow 12 is adjustable.
  • Fig. 5 shows a further embodiment of an inventive Volume flow controller 1, on the upstream side the rotating leg 3 a spring 13 for default a setpoint is provided. Exceeds the speed the flow (a), which is based on the surface elements 8 hits, the spring force of the spring 13, so the pivot legs 3 pivoted with the wing 5 in the direction of arrow 9.
