Pivot Valve Tubular Flow Path for Lower Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid valves suffer from significant pressure losses due to the interference of shutter elements with the fluid flow, and they often require oversized shutter elements to withstand fluid forces, leading to increased dimensions and maintenance issues.
Innovation Solution
A pivoting valve design that incorporates a tubular element mounted on the inside of the valve body, which can move from the outlet hole to the inlet hole when the shutter element is open, reducing pressure losses and preventing fluid from entering the cavity where the shutter element is housed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shutter element is positioned in the flow path to regulate fluid flow, then the valve can control fluid flow effectively, but significant pressure losses occur due to the interference of the shutter element with the fluid flow
Solution Approach 1:
The shutter element is extracted from the main flow path and positioned in a cavity within the valve body. A tubular element is introduced to guide the fluid flow around the shutter element, allowing the shutter to regulate flow without directly obstructing the main flow path, thereby reducing pressure losses while maintaining flow regulation capability.
2Loss of energy
If the shutter element is positioned out of the flow path in a cavity to reduce pressure losses, then pressure losses are reduced, but the circulating fluid can enter the cavity creating turbulence and increasing pressure losses
Solution Approach 1:
A tubular element is introduced as an intermediary component between the main flow path and the cavity containing the shutter element. This tubular element guides the fluid flow around the shutter element, preventing direct entry of fluid into the cavity and eliminating turbulence, thus maintaining both low pressure losses and stable fluid flow.
3Strength
If the shutter element is made larger to withstand fluid forces, then the shutter can resist fluid forces better, but the valve dimensions increase and maintenance becomes more difficult
Solution Approach 1:
The shutter element is extracted from the main flow path and positioned in a cavity, which significantly reduces the fluid forces acting on it. This allows the shutter element to be smaller in size while still maintaining sufficient strength to withstand the reduced fluid forces, thereby reducing overall valve dimensions and simplifying maintenance without compromising strength.
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
The valve achieves reduced pressure losses, extended service life, and decreased maintenance needs, while being suitable for both liquid and gaseous fluids across a wide range of pressures.
Implementation Method 1
a tubular element to channel the flow of fluid within the valve body, the tubular element being interposed between this inlet hole and this fluid flow outlet hole
Implementation Method 2
the tubular element prevents the flow of fluid, which flows through the valve, from entering the cavity where the shutter element is housed when in a normal opening position
Implementation Method 3
a shutter element of the fluid flow passage mounted pivotable on a rotating axis of the valve body to be able to rotate from an open position to a closed position of the fluid flow path
