Electromagnetic Valve Plunger Control Against Pressure Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetically operated valves can experience unauthorized opening due to fluid pressure, leading to inefficient fluid management and increased dependence on solenoid valve manifolds and fluid consumption.
Innovation Solution
The design incorporates an electromagnetically operated valve with a plunger member driven by electromagnetic means, utilizing a coil and ferromagnetic ring to control fluid flow, and includes a closing or opening spring to ensure fluid is only allowed to flow when pressure is sufficient, reducing the magnetic force required for opening and integrating fluid flow control within nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the valve is opened by electromagnetic driving means, then fluid flow is enabled, but fluid pressure may cause unauthorized opening leading to inefficient fluid management
Solution Approach 1:
The patent employs a closing spring that exerts a closing force on the plunger member to counterbalance the fluid pressure force. This spring force acts as a counterweight that prevents the fluid pressure from causing unauthorized opening of the valve, ensuring that the valve opens only when the electromagnetic driving means actively overcomes both the spring force and fluid pressure.
2Ease of operation
If additional valves and solenoid valve manifolds are used for fluid control, then fluid flow management is improved, but device complexity increases
Solution Approach 1:
The patent integrates the fluid flow control function directly into the nozzle structure by incorporating a valve body with inlet and outlet openings formed in the nozzle housing. This merging of the valve and nozzle into a single integrated component eliminates the need for separate solenoid valve manifolds and additional control valves, thereby reducing device complexity while maintaining effective fluid flow management.
3Productivity
If more fluid is consumed for cleaning operations, then cleaning effectiveness is improved, but fluid consumption and cleaning time increase
Solution Approach 1:
The patent implements a pressure feedback mechanism where the closing spring force is calibrated to match the required fluid pressure for effective cleaning. The valve maintains a controlled opening that ensures sufficient fluid pressure is delivered to the cleaning target, optimizing the balance between fluid consumption and cleaning effectiveness. This feedback-controlled pressure regulation prevents both under-pressure (ineffective cleaning) and over-consumption (wasted fluid and time).

Function Achieved in This Case
This solution enables efficient fluid flow management by ensuring fluid is only allowed to flow when pressure is maintained, reducing cleaning times and fluid consumption by 20%, eliminating the need for additional valves, and ensuring all conduits are pressurized until reaching nozzles.
Implementation Method 1
one comprising a coil arranged surrounding a ferromagnetic ring which in turn is arranged surrounding the plunger member for generating an electromagnetic field suitable for driving the plunger member
Implementation Method 2
A closing spring may be provided inside the valve body to bias the plunger member along the same direction as that of the fluid flow direction for ensuring that the plunger member is in a closed position
Implementation Method 3
the plunger member is arranged to be forced by a pressure of flowing fluid into the closed position

AI summary
The electromagnetically operated valve includes a valve body, a plunger member, electromagnetic driving means for driving the plunger member along a flow direction inside the valve body into at least an open position in which a fluid is allowed to flow through the valve body and into a closed position in which the fluid is not, wherein the plunger member is arranged to be forced by a pressure of flowing fluid into the closed position, and to be driven by the electromagnetic driving means into the open position.
