Pressure Reducing Valve Switching Between Regulation and Shut-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure reducing valves require a separate shut-off valve for providing both pressure reduction and shut-off functions, leading to increased space and cost requirements.
Innovation Solution
A pressure reducing valve with a switch valve unit that can transition between pressure reduction and shut-off functions by connecting or disconnecting the pressure zone on the membrane's side to either the inlet or outlet pressure zones, eliminating the need for a separate shut-off valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate shut-off valve is installed in series connection with the pressure reducing valve, then both pressure reduction and shut-off functions are provided, but this increases space requirements and installation costs
Solution Approach 1:
The patent combines the pressure reducing valve and shut-off valve into a single integrated unit. The valve insert serves dual functions: it acts as a pressure reducing valve when opened and as a shut-off valve when closed. This merging eliminates the need for separate valves, reducing installation space and costs while maintaining both functions.
Solution Approach 2:
The valve insert is designed to perform multiple functions within a single component. By configuring the valve insert with a valve stem, spring element, and membrane, it can provide both pressure reduction and shut-off capabilities, making the device universal and eliminating the need for multiple specialized valves.
2Adaptability or versatility
If a separate shut-off valve is installed in series connection with the pressure reducing valve, then both pressure reduction and shut-off functions are provided, but this increases device complexity and costs
Solution Approach 1:
The patent merges two separate valve systems into one integrated valve insert. The valve insert contains all necessary components (valve stem, spring element, membrane) to perform both pressure reduction and shut-off functions, thereby reducing device complexity and eliminating the need for multiple valves and their associated mounting requirements.
Solution Approach 2:
The valve insert is designed as a universal component that can perform multiple valve functions. By making the valve insert multi-functional, the patent reduces the overall system complexity and eliminates the need for separate shut-off and pressure reducing valves, thereby reducing costs and simplifying the system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the pressure reducing valve to function as both a pressure reducing and shut-off valve without the need for additional hardware, saving space and costs.
Implementation Method 1
A first force provided by the spring element acts on a first side of the membrane which tends to open the valve insert
Implementation Method 2
A second force depending on the outlet pressure within the outlet pressure zone acts on a second side of the membrane which tends to close the valve insert
