Explosion Valve Seal Ring Pocket for Flow-Safe Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion protection valves face challenges with sealing ring designs that hinder medium flow and are prone to wear, leading to suboptimal sealing and flow properties.
Innovation Solution
A sealing ring is held in an open receiving pocket within the valve housing, with a flat-rectangular anchoring section and a smooth, hollow chamber design that allows for stable storage and improved sealing without obstructing the flow cross-section, and is positively connected to prevent assembly issues and ensure flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing ring with teardrop-shaped cross-section is fitted onto the housing and bonded in place, then the sealing effect is improved, but the flow cross-section is impeded and the mounting complexity increases
Solution Approach 1:
The sealing ring is repositioned from protruding into the flow path to being received in a pocket on the housing inner surface, effectively moving it to a different spatial dimension that does not interfere with medium flow while maintaining sealing functionality
2Ease of manufacture
If a rectangular sealing ring with 90° external angle is glued into a recessed seat, then the mounting is simplified, but the sealing edge is prone to wear and sealing effect deteriorates
Solution Approach 1:
The sealing ring is designed with non-uniform cross-section featuring a rounded sealing edge that contacts the closing element, while the mounting portion has a different geometry that fits into the receiving pocket, optimizing both sealing performance and mounting ease at different locations
3Ease of manufacture
If adhesive bonding is used to secure the sealing ring, then the assembly process is simplified, but assembly time increases due to drying time and surface preparation requirements
Solution Approach 1:
The adhesive bonding system is replaced with a mechanical retention system where the sealing ring's anchoring section fits into a receiving pocket with a positive-locking connection, eliminating the need for adhesive drying time and surface preparation while simplifying the assembly process
