Valve Core Remover Extension Adapters for Refrigeration Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for removing and replacing valve core elements in pressurized refrigeration systems often face obstructions and fail to couple properly with air conditioning system valve access points, limiting accessibility.
Innovation Solution
A set of extended adapters, including 4⅛″L, 6⅞″L, 20 degree offset, and 90 degree adapters, and an extended rod assembly, designed to couple with a shut-off valve assembly, allowing for improved engagement and removal of valve core elements in pressurized refrigeration systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a universal valve core removal tool is used, then valve core removal capability is provided, but accessibility to service valve points is limited due to tool size
Solution Approach 1:
The valve core removal tool is divided into separate components: a base tool and detachable extension sleeves of various lengths. This segmentation allows the tool to be adapted to different accessibility requirements by attaching appropriate extension lengths, solving the contradiction between maintaining compact base tool size and achieving extended reach to service valve points.
Solution Approach 2:
Extension sleeves are provided in multiple length dimensions, allowing the tool to reach service valve points at different distances and angles. This dimensional variation enables the same base tool to access confined spaces and remote valve locations without increasing the base tool's complexity.
2Ease of operation
If the valve assembly is extended to reach inaccessible valve points, then accessibility is improved, but the extracting rod must pass through additional passageways which may restrict movement
Solution Approach 1:
The extracting rod is designed with dynamic flexibility, allowing it to move freely through the extended passageways created by the valve assembly and extension sleeves. The rod's ability to flex and adjust during insertion and extraction operations enables it to navigate complex multi-passageway configurations without being restricted by the extended tool length.
3Ease of operation
If extensions are added to the valve assembly, then accessibility to confined spaces is improved, but precision in accessing the service valve point may be compromised
Solution Approach 1:
The extension sleeves are designed with specific local qualities at their distal ends, including precisely positioned openings and engagement features that maintain accurate alignment with the service valve point. This localized precision engineering ensures that even when extended into confined spaces, the tool can accurately engage and remove valve cores without compromising engagement precision.

AI summary
Extended adapters for a tool having a shut-off valve assembly used on pressurized refrigeration systems comprises:an extended rod assembly, a 4⅛″L adapter, a 6⅞″L adapter, a 20 degree offset adapter and a 90 degree adapter; the adapters couple the first opening and second opening of shut-off valve assembly; when the 4⅛″L or 6⅞″L extended adapter coupled to second opening of shut-off valve; wherein the extended rod assembly coupled to the adapter and adapted to couple the second opening, the extended rod assembly having a rod adapted to move through the passageway of the extended adapters and the shut-off valve when open, these adapters allow the valve core remover tool to function clear from obstructions.
