Partitioned Fluid Valve Structure for Casing Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fluid control devices require elaborate designs for the fluid control body to match the casing, leading to complex manufacturing processes and high costs, especially due to differences in specifications, pressure, coating, and materials between fluid pipes and control bodies, complicating storage and maintenance.
Innovation Solution
A fluid control device with a standardized on-off valve and partition body that includes a valve seat, valve element, and lid portions, where the partition body is formed separately to enhance structural strength and sealing properties, allowing for easier installation and reduced manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fluid control body is designed with an elaborate shape to match the casing inner surface, then sealing property is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The fluid control body is divided into separate components: valve body, lid portion, and partition body. The partition body is further segmented into wall portion and lid portion that can be assembled separately. This segmentation allows each component to be manufactured independently using standardized processes while achieving the required sealing when assembled together.
Solution Approach 2:
The partition body acts as an intermediary component between the valve body and the casing. It includes a seal component that interfaces with the casing inner surface, while the valve body maintains its standardized shape. This intermediary structure enables sealing without requiring the valve body itself to have an elaborate custom shape.
2Adaptability or versatility
If the fluid control body is separately designed according to regional specifications, then adaptability is improved, but manufacturing cost and storage complexity increase
Solution Approach 1:
The valve body is designed as a universal standardized component that can be used across different regions and applications. The adaptability to regional specifications (pressure, coating, materials) is achieved through the selectable lid portion and partition body combinations rather than customizing the entire fluid control body. This allows a single standardized valve body design to serve multiple purposes.
Solution Approach 2:
By segmenting the fluid control body into standardized valve body and adaptable lid/partition body components, the invention allows selective customization only where needed (lid and partition for regional specs) while maintaining standardized manufacturing for the majority of the structure (valve body), thereby reducing overall manufacturing cost and storage complexity.
3Reliability
If the fluid control body is designed as an integrated elaborate structure, then sealing property is improved, but ease of manufacture deteriorates
Solution Approach 1:
The integrated elaborate structure is broken down into separate manufacturable components: valve body, lid portion, and partition body with wall portion. Each component can be manufactured using standard processes, then assembled together to achieve the sealing function that would be difficult to obtain through a single integrated custom-manufactured piece.

AI summary
A fluid control device has a partition body formed by a wall portion that is provided with a through hole communicating with an opening portion in a valve seat, the wall portion being mounted on the valve seat body in a sealed manner, and a lid portion which is provided continuously to the wall portion, the lid portion covering an opening side of the casing, the partition body including a seal component that seals a gap between an inner surface of a casing and the partition body.
