Fluid Valve With Superposed Shutters For Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid valves with two independent shutters require large dimensions and high energy consumption due to the sequential movement of shutters along the direction of fluid propagation, leading to space and energy efficiency issues.
Innovation Solution
A fluid valve design with a shared movement unit for two shutters, where the first shutter moves transversely to open the inlet and the second shutter moves coaxially to open the outlet, reducing overall dimensions and energy consumption by utilizing magnetic attraction to assist the first shutter's movement and independent elastic means for the second shutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two shutters are positioned in succession along the direction of extension, then the valve can control fluid flow through two independent stages, but the overall dimensions of the valve become large
Solution Approach 1:
The patent repositions the second shutter from a sequential arrangement along the flow direction to a superposed arrangement in a different spatial dimension. The second shutter is placed in the intermediate chamber and moves in a direction superposed with the first shutter's movement direction, effectively utilizing three-dimensional space rather than extending linearly along the flow path. This dimensional reconfiguration maintains two-stage flow control while significantly reducing the valve's overall length and packaging volume.
2Ease of operation
If electromagnetic or pneumatic systems are used to move both shutters independently, then each shutter can be controlled separately, but the energy consumption becomes high
Solution Approach 1:
The patent combines the movement control of both shutters into a single integrated movement unit that can operate in different modes. The movement unit includes a rod that can move the first shutter directly, and also move the second shutter through a through-hole in the shutter body. By merging the control mechanisms and utilizing the superposed spatial arrangement, the system achieves independent control capability while reducing the number of separate actuators and associated energy consumption.
3Reliability
If the shutter moves perpendicular to the gas flow direction, then the shutter can effectively block the flow, but the force required to open the shutter increases due to gas pressure resistance
Solution Approach 1:
The patent introduces a dual-directional shutter movement capability where shutters can move both perpendicular to the gas flow (for effective blocking) and parallel to the gas flow (for easier opening). The second shutter specifically can move in a direction superposed with the first shutter's movement, allowing it to be opened with less force by utilizing the gas flow direction component, while maintaining effective sealing when closed.

Function Achieved in This Case
The design achieves reduced dimensions and lower energy consumption by sharing mechanical components and optimizing energy use, ensuring high safety class certification while maintaining low energy consumption.
Implementation Method 1
In the case of electromagnetic shutters, the shutter is moved by an electromagnetic attraction between a ferromagnetic part, usually mounted on the shutter, and an electromagnetic circuit associated with the frame of the valve.

AI summary
Described is a valve (1) for fluids extending from an inlet duct (2) of the fluid to an outlet duct (3) of the fluid along a main direction of extension (4) and comprising an intermediate chamber (5) positioned between the inlet duct (2) and the outlet duct (3) and having an inlet opening (6) and an outlet opening (7). The valve (1) also comprises a first shutter (11) operatively associated with the inlet opening (6) and movable between an open position and a dosed position along a direction of movement (12) transversal to the main direction of extension (4). In addition, the valve comprises a second shutter (13) operatively associated with the outlet opening (7) and movable between an open position and a closed position of the outlet opening (7). In accordance with this invention, the first shutter (11) and the second shutter (13) are mutually superposed along the direction of movement (12) and the second shutter (13) is also movable along the direction of movement (12).
