Flow Rate Regulator with Decoupled Pressure Control Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow rate regulators exhibit suboptimal control curves with a low-pressure behavior that is less steep than desired and an unwanted ascending high-pressure part, making it challenging to achieve a steep rise at low pressures and a flat or constant plateau at high pressures.
Innovation Solution
The control gap is divided into separate high-pressure and low-pressure regions, with supporting elements decoupling the regulating body's deformation in these regions, allowing independent design of each behavior. This is achieved by forming the control gap with supporting elements that contact the regulating body at zero pressure, creating a wide distance for the low-pressure region and a closer distance for the high-pressure region, ensuring effective decoupling and independent regulation of flow rate behaviors.

Engineering Contradiction Analysis
1Adaptability or versatility
If the control gap is not divided into separate regions, then the structure is simpler, but the low-pressure and high-pressure behaviors cannot be independently optimized
Solution Approach 1:
The control gap is divided into a low-pressure control region and a high-pressure control region by means of support elements. This segmentation allows the regulating body to be deformed independently in each region, enabling separate optimization of low-pressure steepness and high-pressure flatness without mutual interference.
2Adaptability or versatility
If the regulating body is supported at multiple points, then the decoupling of pressure regions is achieved, but the manufacturing complexity increases
Solution Approach 1:
The support elements are integrated into the main body as a single injection-molded component. This merging of the support elements with the main body simplifies manufacturing while maintaining the functional decoupling of pressure regions through the strategically positioned support points.
3Manufacturing precision
If the distance between supporting elements is large in the low-pressure region, then the low-pressure behavior becomes steeper, but the high-pressure control becomes less effective
Solution Approach 1:
The distance between support elements is optimized locally for each pressure region. In the low-pressure control region, support elements are spaced farther apart to enable steeper control, while in the high-pressure control region, support elements are positioned closer together to ensure effective high-pressure regulation. This local optimization resolves the contradiction between low-pressure precision and high-pressure reliability.

Function Achieved in This Case
This approach allows for a steep low-pressure part and a flat high-pressure part of the control curve, enabling precise control of flow rates over a wide pressure range without influencing each other, thus improving the overall performance of the flow rate regulator.
Implementation Method 1
the regulator body deforms in a pressure-dependent manner and closes the control gap
Implementation Method 2
the control gap is divided into the at least two separate regions by supporting elements that support the regulating body already at essentially zero inflow pressure
