Separate Valve Seat Assembly for Backflow and Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve arrangements in fluid pumps are complex to manufacture and assemble, and they often fail to effectively prevent backflow and manage high fluid pressures, leading to inefficiencies and potential damage.
Innovation Solution
A valve arrangement featuring a rotationally symmetrical or spherical closing body that lifts off a valve seat to allow fluid flow in one direction while blocking it in the opposite direction, utilizing a spring-loaded mechanism and a separate valve seat body that can be easily assembled and centered within the pump housing, reducing the need for additional centering elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional valve arrangement is used in a fluid pump, then the valve can control fluid flow direction, but the manufacturing and assembly become complex
Solution Approach 1:
The valve arrangement is divided into separate functional components: a closing body (check valve element) and a valve seat formed by the pump housing itself. This segmentation allows the valve seat to be integrated into the housing structure while the closing body remains a separate, simple component that can be easily manufactured and assembled, thereby reducing overall manufacturing and assembly complexity while maintaining flow control functionality.
Solution Approach 2:
The pump housing is designed to serve multiple functions: it provides structural support, contains the fluid passage, and forms the valve seat for the check valve. By making the housing multi-functional, the number of separate components is reduced, eliminating the need for additional centering elements and simplifying both manufacturing and assembly processes while maintaining reliable fluid flow control.
2Ease of manufacture
If a separate valve seat body is used, then assembly is simplified, but additional centering elements are typically required
Solution Approach 1:
The pump housing is designed to simultaneously serve as the structural enclosure, fluid passage container, and valve seat formation. This multi-functionality eliminates the need for separate centering elements that would otherwise be required when using a detachable valve seat body, as the housing itself provides the precise positioning and centering for the closing body during assembly.
Solution Approach 2:
The valve seat function is merged directly into the pump housing structure rather than being a separate component. This merging eliminates the interface between separate parts that would require centering elements, simplifying assembly while maintaining the ability to easily manufacture and replace the closing body independently if needed.
