Sanitary Valve Housing Struts for Axial and Torsional Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary installation parts, such as valves, face mechanical stress issues due to axial and torsional forces during installation, leading to a risk of housing breakage or deformation, necessitating an enhancement in mechanical strength.
Innovation Solution
The design incorporates support struts with inclined lateral boundaries and varying fastening areas to optimize force transmission, allowing for better absorption of axial and torsional forces, thereby increasing the mechanical strength and resilience of the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sanitary fittings are clamped during installation to ensure tight seal, then sealing performance is improved, but mechanical strength of housing deteriorates due to axial and torsional stresses
Solution Approach 1:
The housing is divided into upper and lower parts connected by support struts, creating a segmented structure that can better distribute and absorb installation stresses while maintaining sealing performance
Solution Approach 2:
The support struts are designed with asymmetric fastening areas where the upper and lower fastening regions cover different circumferential sections, allowing optimized distribution of axial and torsional forces during installation
2Device complexity
If support struts are designed with vertical fastening areas, then structural simplicity is maintained, but force transmission capability deteriorates under axial and torsional loads
Solution Approach 1:
The support struts feature asymmetric fastening areas with inclined lateral boundaries, where upper and lower fastening regions cover different circumferential sections, optimizing the transmission of axial and torsional forces while maintaining structural efficiency
Solution Approach 2:
The lateral boundaries of the fastening areas are inclined at specific angles relative to the axial direction, changing the geometric parameters to improve force transmission capability under axial and torsional loads
