Definitions

  • the invention relates to a throttle valve for air conditioning systems with a housing which has a supply air connection and an exhaust air connection and a central axis of rotation for a flap which can be pivoted between an open position and a closed position, with several in the flow direction behind the flap and outside the pivoting range of the flap Turbulence grids for suppressing large-volume turbulence bales are arranged, at least one of which extends in the direction of flow in the region of the central plane of the housing and is arranged fixed to the housing.
  • Throttle valves are known in various designs. They control the air flow to a room or the like. Therefore throttle valves are usually designed as an actuator of a corresponding control. Because a throttle valve is to be used to control or regulate the air flow over a wide range until it is completely shut off, flow conditions result in particular in the case of flap positions in the vicinity of the closed position, which favor the generation of low-frequency noise.
  • angular turbulence grids are arranged in the throttle valve of the type described at the beginning (FR-A-2 158 408) behind the valve and outside the pivoting range of the valve. This can also help prevent low-frequency noise.
  • FR-A-2 158 408 angular turbulence grids are arranged in the throttle valve of the type described at the beginning (FR-A-2 158 408) behind the valve and outside the pivoting range of the valve. This can also help prevent low-frequency noise.
  • the invention has for its object to improve a generic throttle valve so that the generation of low-frequency noise is avoided with the lowest possible pressure loss.
  • the turbulence grids extend in the direction of flow, turbulence bales are nevertheless detected and resolved, and thus the generation of low-frequency noises is prevented. Even if the turbulence bales do not hit the turbulence grids, but move past them, the turbulence bales are nevertheless influenced by the grille, because to destroy or reduce the size of the turbulence bales, it is sufficient if their outer regions are gripped by the turbulence grids extending in the flow direction. Since these turbulence grids, which extend in the flow direction, represent practically no resistance to the flow, the pressure loss is also low.
  • the turbulence grids can consist of perforated plates. Turbulence grids which have a free cross section between 30% and 70% of their area have proven to be particularly favorable.
  • the turbulence grids described are particularly effective in the case of a throttle valve, the flap of which is arranged at an angle of 60 ° to the central plane of the housing in the closing direction.
  • a supply air duct and an adjoining exhaust air duct with a larger cross section can also be formed in the housing, the flap in the supply air duct and the turbulence grilles being arranged in the exhaust air duct.
  • the resulting sudden cross-sectional expansion in the transition area between the supply air duct and the exhaust air duct is harmless because the turbulence bales which are created there are also captured by the turbulence grids.
  • an arrangement is favorable in which the transition between the supply air duct and the exhaust air duct follows the line of contact between the supply air duct and the closed flap.
  • the throttle valve shown includes a housing 1 with a supply air connection 2, from which a supply air duct 3 extends.
  • An exhaust air duct 4 adjoins the supply air duct 3 and ends at an exhaust air connection 5.
  • the flap 7 can be designed as an actuator of a control system, not shown. Accordingly, an actuator (not shown) can act on the axis of rotation 6.
  • the flap 7 can be pivoted in the direction of the arrows 8 between an open position, which is shown with solid lines, and a closed position, which is shown with dash-dotted lines.
  • An arrow 9 indicates the direction of flow of air through the housing 1.
  • the flap 7 has a base area such that, in the closed position, it makes an angle of approximately 60 'to the central plane 10 of the housing 1.
  • the resulting line of contact 11 between closed flap 7 and supply air duct 3 practically also forms the end of supply air duct 3 or the transition between supply air duct 3 and exhaust air duct 4.
