Integrated Valve Plug Trim for Compact Pressure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-stage valve trim assemblies are costly, difficult to manufacture, and generate noise due to pressure reduction, while also occupying more internal space, making them inefficient for fluid flow control in process plants.
Innovation Solution
A plug integrated staged trim assembly with a valve plug featuring a hollow central chamber and multiple openings for pressure recovery, along with a plug guide and independent seat, which reduces manufacturing costs and noise, and allows for a compact design with fewer parts, enhancing fluid flow and thermal compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If multi-stage valve trim assemblies are used to control fluid flow and reduce pressure, then pressure control capability is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent combines multiple pressure recovery stages into a single integrated valve plug body. The plug incorporates internal flow passages and chambers that perform the function of multiple separate stages, eliminating the need for multiple discrete components while maintaining pressure control capability.
Solution Approach 2:
The valve plug is designed as a multi-functional component that simultaneously performs flow control, pressure recovery, and noise reduction functions. The integrated design allows a single component to replace what would traditionally require multiple specialized parts.
2Stress or pressure
If multi-stage valve trim assemblies are used for pressure recovery, then pressure control is improved, but manufacturing difficulty increases
Solution Approach 1:
By merging multiple pressure recovery stages into one plug component, the invention reduces the total number of parts that need to be manufactured, assembled, and inspected. This integration simplifies the manufacturing process while achieving the same pressure recovery function.
3Stress or pressure
If multi-stage valve trim assemblies are used to characterize fluid flow, then pressure reduction capability is improved, but noise generation increases
Solution Approach 1:
The invention converts the potentially harmful effect of pressure reduction (which generates noise) into a beneficial controlled process. The carefully designed internal passages and chambers guide fluid flow to reduce pressure while minimizing turbulence and noise generation.
4Stress or pressure
If multi-stage valve trim assemblies are used for fluid control, then pressure control capability is improved, but internal space requirements increase
Solution Approach 1:
The invention uses a nested design where internal flow passages and chambers are contained within the valve plug body itself. The multi-stage pressure recovery features are nested within the single plug component, maximizing space utilization and reducing the overall volume required.
