DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a regulating device for controlling the flow of a fluid from a run-off opening of a container. The regulator entails a throttling unit that is designed to pivot on an axis and in this manner control the diameter of the closure of the run-off opening.
An object of the present invention is to construct a regulating device distinguished both by compactness of construction and minimum maintenance.
This object is achieved with a regulating device in which a throttling unit is united operatively with a pressure detector that governs said throttling unit in the closure of the diameter of said run-off opening.
The throttling member can also be rigidly united with the pressure detector.
Preferably the regulating device is set in a throttling chamber that consists of an output control area, which is open on one side to the atmosphere, and of a run-off area. The throttling unit united rigidly with the pressure detector together form a compact structural unit. The pressure detector is united with said throttling unit at such an angle that, with any position of the throttling unit, the pressure detector maintains a seal with its outer contour along an inner contour of the output control area corresponding to it.
Regulating devices of this type are commonly used where, in spite of varying in-flow volume, the volume of discharge from a container is desired to be controlled. Thus, the present invention is intended not just for rain retention basins, but, for example, for dairies and breweries.
The present invention is a regulating device distinguished by minimum space requirements, few moving and/or nonmoving parts, relatively low production costs and high reliability of operation. Because of little need for space, the invention can be used in relatively small rain water retention basins or similar containers. For example, it can be built into an existing basin or container enclosed in a housing. In addition, one feature of the structural design and the anticipated location of installation--in the area at the bottom of the container--is that the invention is not susceptible to deposits of debris.
The pressure detector, which functions as the control element for the throttling unit, as well as the throttling unit itself, can have various construction designs.
Preferred designs of the invention are the subject of the subclaims.
The pressure detector can be fastened to a rocking shaft running perpendicular to the run-off direction. The rocking shaft activates the throttling flap. In this case, the hydrostatic water pressure works against the pressure detector on one side and against the throttling flap on the other.
With another arrangement of the device, the pressure detector can be fastened to a rocking shaft running parallel to the run-off direction, in which case a throttling plate is installed, that is guided operatively, perpendicular to the run-off opening on one and/or the other end of the rocking shaft. This design permits the invention to be set up in a recess of the basin wall, for example.
A further design appropriate for the recommendation of claim 6 is possible, in which the pressure detector has the shape of a piston that is extended lengthwise in an area controlling the range of output which is appropriate for its diameter. The piston acts upon a corresponding throttling plate by way of a suitable transfer of force, for example, a linkage gear. The compensating unit that reacts counter to the water pressure is preferably designed as a moveable counterweight, commonly known for this purpose, so that the pressure detector, as given in claim 7, is weighted with a moveable counterweight. Along with this, the compensating unit can also entail an appropriate mechanical and/or hyro-pneumatic spring with given, individual, and, if necessary, adjustable characteristics.
As in claim 9, the invention includes a throttling flap which can be designed as a hollow body. With this structure, the throttling flap's wall facing the pressure detector is larger in surface area than the regulating
