Multi-Ported Refrigeration Valve Layout Against Particulate Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration valves in commercial and industrial systems face issues with particulate buildup, leading to reduced valve life and operational failures, as existing designs often locate hand valves at the bottom, where particulates accumulate, hindering fluid flow.
Innovation Solution
The refrigeration valve design positions hand valves at the top of the valve body, along with an expansion valve and regulator valve, to prevent particulate accumulation, featuring a strengthening rib with drain/test ports and a strainer for filtering, ensuring reliable operation and extended valve life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand valves are located at the bottom of the valve body, then ease of operation is improved, but particulate buildup occurs leading to reduced valve life and operational failures
Solution Approach 1:
The patent inverts the conventional location of hand valves from the bottom to the top of the valve body. This inversion prevents particulates from accumulating in the valve mechanism by allowing them to settle at the bottom of the flow passage away from the valve components, thereby maintaining valve reliability while preserving ease of operation.
Solution Approach 2:
The patent extracts the hand valves from the bottom location and relocates them to the top of the valve body. This separation removes the hand valves from the particulate-prone zone at the bottom, preventing contamination while maintaining operational accessibility.
2Ease of operation
If hand valves are located at the bottom of the valve body, then ease of operation is improved, but fluid flow is hindered due to particulate accumulation
Solution Approach 1:
By inverting the hand valve location from bottom to top, the patent ensures that particulates settle at the bottom of the flow passage rather than accumulating in the valve mechanism. This maintains smooth fluid flow through the valve while preserving ease of operation.
3Adaptability or versatility
If multiple valves are provided in the valve body, then functionality and control are improved, but device complexity increases
Solution Approach 1:
The patent merges multiple valve functions (hand valves, expansion valve, regulator valve) into a single integrated valve body assembly. This consolidation provides enhanced functionality and control while managing complexity through unified design rather than separate components.
Solution Approach 2:
The valve body is designed as a multi-functional unit that accommodates different valve types (hand valves for isolation, expansion valve for flow control, regulator valve for pressure control) within a single assembly, providing versatility without proportionally increasing complexity.

AI summary
A refrigeration valve having a valve body having an inlet, an outlet, and a flow passage defined therebetween, an expansion valve in the flow passage, a first hand valve between the inlet and the expansion valve, and a second hand valve between the outlet and the expansion valve. The first and second hand valves are provided at a top of the valve body and are movable in a first direction for preventing fluid flow through the flow passage. By providing the first and second hand valves at the top of the valve body rather than at a bottom of the valve body, valve life is increased and the valves are not prevented from operating due to particulate build up in the valves.
