Slide Solenoid Valve Lever Actuation for 0 Bar Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slide solenoid valves face challenges such as increased dimensions due to servo control, requirement of pressurized fluids, potential for malfunctions, lack of total fluid separation, limited flow rates, and high energy consumption, which restrict their use in various sectors like chemical, petrochemical, and food industries due to safety and compatibility issues.
Innovation Solution
A lever actuation system that amplifies the motion of the movable core, allowing for greater slide displacement without the need for servo control or increased power, enabling total fluid separation and operation at 0 bar pressure, thus reducing overall dimensions and energy consumption while increasing flow rates and pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If servo control is used to actuate the solenoid valve, then the valve can achieve precise control functions, but the overall dimensions of the valve increase
Solution Approach 1:
The patent removes the servo control system from the valve structure, extracting the function that caused dimensional increase. The valve is actuated directly by electromagnetic force without requiring a separate servo control mechanism, thereby reducing overall valve dimensions while maintaining operational capability.
Solution Approach 2:
The patent replaces the mechanical servo control system with a direct electromagnetic actuation system. Instead of using mechanical linkages and servo mechanisms, the valve uses electromagnetic force to directly move the slider, eliminating the need for complex mechanical control structures.
2Ease of operation
If pressurized control fluid is used for servo control actuation, then the valve can function properly, but additional fluid systems and auxiliary means are required
Solution Approach 1:
The patent replaces the hydraulic/pneumatic servo control system with a direct electromagnetic actuation system. The electromagnetic coil generates force directly to move the slider without requiring pressurized control fluid, auxiliary tanks, compressors, or complex fluid distribution channels.
Solution Approach 2:
The patent extracts and removes the entire pressurized fluid control system from the valve structure. By using direct electromagnetic actuation, the valve no longer requires independent fluid supply systems, charge/discharge tanks, or complex fluid management infrastructure.
3Quantity of substance
If the processed fluid is used for servo control, then fluid quantity is reduced, but total fluid separation cannot be achieved
Solution Approach 1:
The patent replaces the fluid-based servo control system with electromagnetic actuation, eliminating the need to choose between using processed fluid for control or maintaining separation. The electromagnetic system requires no fluid at all for actuation, thereby achieving total fluid separation while maintaining full valve functionality.
4Ease of operation
If inlet pressure different from 0 bar is required for actuation, then the valve can open and close passages, but the valve cannot operate at atmospheric pressure
Solution Approach 1:
The patent replaces the pressure-dependent mechanical actuation system with an electromagnetic system that generates force independently of inlet pressure. The electromagnetic coil can produce sufficient force to move the slider regardless of whether the inlet pressure is 0 bar or higher, enabling operation across the full pressure range including atmospheric pressure.
