Modular Fluid Control Valve Structure for Casing Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid control devices require elaborate designs and separate manufacturing of fluid control bodies to match the shape of the casing, leading to increased costs and complexity in design, manufacturing, and management, especially when dealing with varying specifications and standards across different regions.
Innovation Solution
A fluid control device using a standardized on-off valve with a partition body that includes a valve seat, wall, and lid portions, which are separately manufactured and mounted to the casing, providing sealing and structural integrity without requiring custom designs for each casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fluid control body is designed with an elaborate shape to closely connect to the inner surface of the casing, then the sealing property is improved, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The fluid control body is divided into separate modular components: a standardized valve body and a custom-machined casing. The casing is manufactured as a separate component with the elaborate shape needed for sealing, while the valve body remains a simple standardized component. This segmentation allows each part to be manufactured independently using appropriate methods, reducing overall complexity.
Solution Approach 2:
The elaborate sealing shape is extracted from the valve body design and transferred to the casing design. Instead of making the valve body conform to the casing's inner surface, the casing is made to conform to the valve body's simple cylindrical shape, with the sealing features implemented on the casing's outer surface.
2Adaptability or versatility
If the fluid control body is separately designed and manufactured according to regional specifications and standards, then the adaptability to different regions is improved, but the manufacturing cost and storage complexity become enormous
Solution Approach 1:
The system is segmented into a universal standardized valve body that can be manufactured once and used everywhere, and a regional-specific casing that is manufactured locally according to regional specifications. This allows the expensive-to-manufacture standardized component to be produced in volume at low cost, while the adaptive component is produced locally.
Solution Approach 2:
The standardized valve body is designed with universal mounting interfaces and dimensions that allow it to be installed in casings from different regions with different specifications. The valve body serves multiple regions simultaneously, eliminating the need for separate valve body designs for each region.
3Strength
If the fluid control body is designed with elaborate lid portions and wall portions, then the structural strength is improved, but the design and manufacturing process becomes complicated
Solution Approach 1:
The structural components (lid portions, wall portions, partition walls) are segmented and integrated into the casing design rather than being separate parts of the valve body. The casing itself is machined to provide the necessary structural strength and rigidity, eliminating the need for complex separate structural components.
Solution Approach 2:
The structural support functions and the sealing containment functions are merged into a single integrated casing component. The casing simultaneously provides structural strength to support the valve body and provides the elaborate shape needed for sealing against the pipe flange and surrounding structures.
