Solution Overview
Problem
Existing flow rate regulators for gas boilers require complex structural adjustments for different installation situations, making them difficult to use in various conditions and necessitating separate versions for different regions, which is costly and inefficient.
Innovation Solution
A flow rate regulator with a regulator housing designed as a built-in cartridge, featuring a control core on a threaded spindle that can be manually or motor-driven to adjust the control gap, allowing for pressure-independent flow rate adjustment without needing extensive structural adaptations, and includes a handle for easy operation and secure setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If flow rate regulators are designed with complex structural adjustments for different installation situations, then the flow rate can be precisely regulated, but the device complexity increases and handling becomes significantly more difficult
Solution Approach 1:
The flow rate regulator is divided into modular components: a cartridge body, a control core assembly with threaded spindle, and a throttle body. This segmentation allows each component to be optimized independently while simplifying the overall structure and assembly process, resolving the contradiction between precision and complexity.
Solution Approach 2:
The control core is designed with a threaded spindle that converts rotational movement into longitudinal displacement, dynamically adjusting the control gap between the control core and throttle body. This dynamic adjustment mechanism enables precise flow rate regulation through a simple rotational operation, avoiding complex structural adjustments.
2Adaptability or versatility
If flow rate regulators are designed with complex structural adjustments, then the flow rate can be adapted to different conditions, but the ease of operation deteriorates and handling becomes significantly more difficult
Solution Approach 1:
The regulator housing is designed as a universal cartridge that can be installed in various situations without requiring structural adjustments. The standardized interface and compact design allow the same device to be used across different applications, maintaining adaptability while simplifying operation.
Solution Approach 2:
The threaded spindle automatically converts rotational input into precise longitudinal movement of the control core, self-regulating the control gap without requiring manual structural adjustments. This self-service mechanism simplifies operation while maintaining adaptability to different flow rate requirements.
3Adaptability or versatility
If separate fixed flow rate regulator versions are manufactured for every country or region, then the flow rate can be optimized for local conditions, but the device complexity increases and storage needs increase
Solution Approach 1:
Instead of manufacturing separate fixed flow rate regulators for different regions, this invention uses a single dynamic regulator model where the flow rate can be adjusted by rotating the threaded spindle to change the control gap. This eliminates the need to store multiple versions while maintaining regional adaptability.
Solution Approach 2:
The flow rate is adjusted by changing the parameter of the control gap size through rotational movement of the threaded spindle, rather than manufacturing different physical devices. This allows a single regulator to serve multiple regional requirements, significantly reducing storage needs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy installation and adaptation to various conditions without complex structural adjustments, ensuring a universal flow rate regulator that can be used across different situations, simplifying handling and securing the set flow rate, thus reducing storage needs and facilitating use in diverse applications.
Implementation Method 1
The control core is held on a threaded spindle and is displaceable in the longitudinal direction in such a way that to vary the control gap by changing the relative position of the control core and throttle body, a rotary movement of the threaded spindle can be converted into a longitudinal movement of the control core
Implementation Method 2
an annular throttle body made of elastic material, which delimits a control gap between itself and a control core. The control core has a control profiling on its outer circumference, into which the ring-shaped throttle body is increasingly shaped under the increasing pressure of the water flowing through the control gap

AI summary
The flow volume regulator (1) has an annular throttle body made of elastic material. A regulator housing is designed as integrated cartridge or insertable cartridge. The throttle body is arranged such that a housing opening is provided at the housing periphery of the control tappet. The throttle body surrounds the control tappet. The housing opening is formed as fluid intake (21).
