Definitions

  • the invention relates to a mechanically self-acting volumetric flow controller, in particular for raumlufttechnische, flowed through by a medium systems, having a wall having a part of a flow channel forming housing, with a inside the housing on a transversely arranged to the flow wave wave flap, wherein the flap under the action of the fluid flowing against the flap against a restoring force from an open position into a closed position is pivotable and pivots back at the decreasing volume flow of the flowing medium by the restoring force back to the open position.
  • the flap may be rotationally fixed to the shaft, so that then rotates the shaft relative to the housing.
  • the shaft can be mounted on one side or on both sides relative to the housing.
  • the shaft may be rotatably mounted on the housing. In this case, then the flap rotates around the shaft. In this case, only one end or both ends of the shaft on the housing be attached.
  • the housing may each have an inwardly facing stub shaft in two opposite areas. In mechanically self-acting volume flow controllers, the flap is pivoted under the action of the material flowing against the flap against a restoring force from an open position to a closed position.
  • volumetric flow controllers work mechanically automatically, because the flow-related control valve torque is compensated by the restoring force, which is usually generated by a spring.
  • a disadvantage of known volumetric flow controllers is that the position of the flap is not visible from the outside. Therefore, not always an energy-optimized operating point is adjustable because - if the flap has almost reached its closed position, for example, which is not visible from the outside - high pressure losses are the result. From the GB 2468292 A a throttle device is known which comprises a pivotally mounted in a housing butterfly valve.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a volumetric flow regulator in which the flap position can be determined from outside the housing without disassembly.
  • This object is achieved in that inside and / or outside of the housing with the flap and / or with the shaft directly or indirectly connected and according to the movement of the flap also moving display element is provided which for visual inspection of the position of the flap from outside of the housing free is arranged visible. Due to the inventive design, the position of the flap can be determined at any time from outside the housing. Since automatically mechanical Working regulators usually have an externally accessible setpoint adjustment, the setpoint can be optimally adjusted while monitoring the flap position. As a result, an energy-optimized adjustment of the operating point is possible.
  • At least one end of the shaft itself may be formed as a display element.
  • the display element may represent a painted marking or a notch. It is also conceivable, for example, a line which is aligned parallel to the flap.
  • the display element may alternatively be formed as a separate component.
  • the display element may be attached to one end of the shaft. This may for example be a plugged onto the end of the shaft disc having a corresponding mark.
  • the display element can be arranged within the housing, and the housing can, at least in the region of the display element moving according to the movement of the flap, consist of a transparent material or have a recess, in particular closed with a viewing window.
  • the housing may have a transparent viewing window which is designed so large that the display element is visible in every position of the flap and thus the flap position can be determined.
  • a recess in the wall of the housing is conceivable, the an observation of the aligned, arranged in the interior of the housing end of the shaft allows.
  • the housing may have at least one recess as a bearing for one end of the shaft.
  • the display element may be attached to the outside of the recess projecting end of the shaft.
  • the outside of the recess protruding end of the shaft itself may be formed as a display element.
  • a device for generating the restoring force On the outside of the housing, at least part of a device for generating the restoring force, in particular the entire device for generating the restoring force, is arranged.
  • a device for generating the restoring force is characterized in that the shaft has a lever arm, on which hingedly engages a spring, wherein the spring may be, for example, a leaf spring, one end of which is connected to the lever and the other end to a cam is fixed, that upon adjustment of the cam about a pivot point, the leaf spring is taken from the cam and rolls on the curve, and that means for fixing the cam is provided.
  • a connecting rod or a connecting cable may be provided for connecting the lever to the associated end of the leaf spring.
  • a fixing device for fixing the device for generating the restoring force On the outside of the housing, at least part of a fixing device for fixing the device for generating the restoring force, in particular the entire fixing device for fixing the device for generating the restoring force, be arranged. If the device for generating the restoring force has a cam for setpoint adjustment, the fixing device may be formed, for example, as a screw, which enables after loosening a rotation of the cam.
  • the housing has an outside cover which covers at least a portion of the part of the fixing device arranged outside the housing on the outside in the direction of the longitudinal extension of the shaft and / or the outside at least a portion of the outside of the housing part of the device for generating the restoring force in the direction of the outside covering the longitudinal extent of the shaft and / or covers the at least a portion of the arranged outside the housing part of the display element on the outside in the direction of the longitudinal extent of the shaft, wherein either the cover at least in the region of the corresponding movement of the flap also moving display element of a transparent Material consists or one, in particular closed with a viewing window, recess or the display element is outside the cover.
  • the display element may be formed, for example, as a disk or as a disk segment that, for example, laterally protrudes from the cover and thus allows reading.
  • the cover may consist of a sheet metal. Of course, other materials are conceivable. The design of a perforated plate, from a grid, from a transparent material or the like is possible.
  • the cover may have a, preferably circumferential, angled in the direction of the housing collar. Then the area covered by the cover is not visible from the side.
  • a mechanically self-acting volume flow controller is shown in angular design. This has a, having a wall and a part of a flow channel forming housing 1. At each of the two free ends of the housing 1, a flange 2 is formed. By means of the flanges 2, the volumetric flow controller can be connected to air ducts, not shown. Other cross sections of the volumetric flow controller are also conceivable. Thus, the volumetric flow controller may be round and connected by means of suitable Aufschiebemuffen with the air ducts, not shown.
  • a flap 5 is pivotally mounted on a shaft 4 arranged transversely to the flow direction 3.

  • the flap 5 is under the action of a flowing the flap 5 medium against a restoring force from its open position, and they, for example, in Fig. 3 is shown, pivotable in its closed position. With decreasing volume flow of the flowing medium, the flap 5 is pivoted back by the restoring force in its open position.
  • a respective recess 6 is provided in two opposite walls, through which the respective end 7 of the shaft 4 is passed to the outside.
  • the recesses 6 serve insofar as storage for the shaft 4.
  • the shaft 4 is sealed in the region of the two recesses 6 by seals, not shown, relative to the housing 1.
  • a display element 8 plugged in the form of a separately formed component.
  • This display element 8 has a marking in the form of a line. The stroke is aligned parallel to the position of the flap 5. The display element 8 rotates when changing the position of the flap 5 with.
  • a cover 9 is provided on the side of the housing 1, on which the display element 8 is arranged.
  • This cover 9 consists in the illustrated embodiment of a planar element with two opposite, aligned orthogonal to the flow direction 3 short edges 10 and two opposite, parallel to the flow direction 3 aligned long edges 11th
  • Each of the two short edges 10 touches the respectively adjacent flange 2 and can be secured in a manner not shown on this flange 2.
  • the cover 9 is angled in the direction of the housing 1 to form a collar 19.
