Modular Pressure Regulating Valve for Pre-Tested Seal Seat Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure regulating assemblies in beverage systems suffer from seal seat failures, which can go undetected until installation, leading to inefficiencies and material waste.
Innovation Solution
A pressure regulating valve with a removable seal seat housed in a separate housing, allowing pre-installation testing and easy retrofitting into existing systems, ensuring a functional seal seat is installed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seal seats are integrated directly into the regulator body, then the structure is simpler and manufacturing is easier, but the seal seats cannot be tested prior to installation and must be replaced as complete units
Solution Approach 1:
The seal seat is separated from the regulator body and placed in a removable housing that can be independently tested. This segmentation allows the seal seat to be quality-tested before final installation while keeping the overall regulator structure manageable through modular design.
Solution Approach 2:
The seal seat is quality-tested in the removable housing before being installed in the regulator body. This preliminary testing action ensures seal seat functionality is verified in advance, preventing installation of defective seal seats while maintaining structural simplicity.
2Ease of repair
If seal seats are made replaceable, then defective seal seats can be replaced, but the replacement process becomes more complex and time-consuming
Solution Approach 1:
The seal seat is contained in a removable housing that can be quickly detached from the regulator body. This segmentation allows the entire housing with seal seat to be replaced as a single unit, simplifying the repair process and reducing replacement time compared to handling individual seal seats.
Solution Approach 2:
The seal seat is pre-tested in the removable housing before installation. This preliminary action ensures that when replacement is needed, a known-good seal seat is already in the housing, eliminating the need for on-site testing and reducing overall replacement time.
3Reliability
If seal seats are tested after installation, then testing can be performed, but defective seal seats are discovered too late causing inefficiencies and material waste
Solution Approach 1:
The seal seat is quality-tested in the removable housing before being installed in the regulator body. This preliminary testing action discovers defective seal seats in advance, preventing waste of installation time and materials while ensuring only functional seal seats are installed.
Solution Approach 2:
The removable housing serves as an intermediary between seal seat manufacturing and final regulator assembly. This intermediary allows quality testing to occur at the housing level before commitment to final installation, reducing material waste while maintaining reliability.
4Adaptability or versatility
If the housing is designed to fit existing regulator bodies, then retrofittability is improved, but the housing design becomes more complex
Solution Approach 1:
The removable housing is designed with universal mounting features that allow it to fit multiple existing regulator body types. This universality achieves retrofittability across different models while the housing itself maintains a standardized design, avoiding excessive complexity.

Function Achieved in This Case
Ensures reliable seal seat installation by allowing pre-installation testing, reducing time and material costs, and facilitating quick replacement.
Implementation Method 1
A biasing element biases the seat stem in the closed position

AI summary
A pressure regulating valve including a seal seat that defines an opening. A seat stem is moveable between a closed position in which the seat stem engages the seal seat and prevents fluid flow through the opening, and an open position in which the seat stem is spaced from the seal seat and permits fluid flow through the opening. A biasing element biases the seat stem in the closed position. A housing defines a passage that extends between an inlet and an outlet. The seal seat, seat stem and biasing element are positioned in the passage such that movement of the seat stem between the closed and open positions controls flow of the fluid between the inlet and outlet. The housing has an outer wall including a coupling mechanism for fixing the housing inside a channel of a primary regulator body.
