Air Release Valve Cover Quick-Release Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air release valves require time-consuming disassembly and reassembly processes for maintenance, especially when backflushing, and lack a quick and tool-free method for removing and replacing the valve cover to ensure a proper seal.
Innovation Solution
A quick release mechanism with radially tapered grooves and guides allows the valve cover to be easily removed and reattached by hand, creating an air-tight seal without the need for tools, by engaging and disengaging a shoulder piece within a locking pocket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bolted valve cover design is used, then reliable air-tight seal is achieved, but maintenance time and complexity increase significantly
Solution Approach 1:
The valve cover assembly is segmented into modular components with a quick-release mechanism that divides the connection system into detachable parts. The valve cover includes a quick-release assembly with a release lever that separates the valve cover from the valve body without requiring bolt removal, enabling rapid maintenance access while maintaining seal integrity through integrated gasket design.
Solution Approach 2:
The quick-release mechanism introduces dynamic elements including a movable release lever and spring-loaded locking pins that transition between locked and unlocked states. The locking pins are biased by springs to automatically engage with recesses in the valve body, providing dynamic sealing pressure adjustment that maintains reliable air-tight seals during operation while allowing quick release when needed.
2Strength
If bolted valve cover design is used, then secure connection is achieved, but ease of operation for quick removal deteriorates
Solution Approach 1:
The quick-release mechanism incorporates self-servicing features where the spring-loaded locking pins automatically engage with recesses in the valve body when the valve cover is positioned, eliminating the need for manual alignment or tightening operations. The system self-regulates the connection strength through spring pressure while allowing operator-initiated quick release via the release lever.
Solution Approach 2:
The release lever acts as an intermediary mechanism that translates operator input into the simultaneous movement of multiple locking pins. When the release lever is actuated, it lifts the locking pins from their engaged positions with the recesses in the valve body, providing a mechanical advantage that enables easy removal while maintaining strong connection during operation.
3Reliability
If multiple bolts are used to secure valve cover, then seal reliability improves, but device complexity and assembly time increase
Solution Approach 1:
Multiple sealing functions are merged into a single integrated gasket system that is pre-installed on the valve cover body. The gasket incorporates sealing surfaces and compression elements that work together with the quick-release mechanism to provide reliable air-tight seals without requiring multiple separate sealing components or complex assembly procedures.
Solution Approach 2:
The quick-release mechanism with locking pins serves multiple functions simultaneously: it provides mechanical connection, maintains sealing pressure, enables quick release, and guides proper alignment during assembly. This multi-functional design replaces the need for multiple bolts and separate gasket installation steps, reducing overall device complexity while maintaining seal reliability.

AI summary
The problem of disassembling an air release valve in the field by removing the valve cover to remove the internal working components is solved by a quick release mechanism on the valve cover that can be operated by hand. The quick release mechanism can include a radially tapered groove with tapered parallel tracks that define a slot in the valve cover and a guide on the valve body that engages with the tracks through the slot. The guide can be inserted into a socket in the radially tapered groove and a shoulder piece on the guide can slide on the tapered parallel tracks, which brings the valve cover towards the valve body. An O-ring and a U-cup seal arranged in recesses in the valve body can be compressed by the valve body cover to form airtight seals and the shoulder piece can be lodged in a locking pocket to keep the valve cover in place.
