Solution Overview
Problem
Existing filtering plants face challenges in regulating pressure instantaneously, particularly during clogging of filtering devices and conduits, leading to potential damage and inefficiencies due to the use of electric actuators with long response times.
Innovation Solution
The implementation of a mechanically actuated spring valve as a pressure regulating mechanism, which replaces electric actuators, allowing for immediate and proportional adjustments in pressure to maintain safety limits, thereby preventing damage to capillaries and enhancing filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric actuators are used for pressure regulation, then the plant can maintain pressure within safety limits, but the response time is too long to prevent capillary damage during clogging
Solution Approach 1:
The patent replaces electric actuators with a purely mechanical pressure regulation system consisting of a spring-loaded valve and bellows mechanism. The spring force directly balances the pressure force on the bellows, providing instantaneous mechanical response without electrical delays. This mechanical substitution resolves the contradiction by eliminating the slow response time of electric actuators while maintaining reliable pressure regulation within safety limits.
Solution Approach 2:
The mechanical pressure regulation system is self-acting and automatic, requiring no external power source or control signals. The spring-loaded valve automatically adjusts the discharge opening based on the balance between spring force and pressure force on the bellows, providing instantaneous response to pressure changes during clogging events. This self-service mechanism resolves the response time contradiction by eliminating dependence on external electrical control systems.
2Reliability
If electric actuators with control circuits are used, then pressure can be regulated, but the device complexity increases
Solution Approach 1:
The patent extracts and eliminates all electrical control circuits, sensors, and actuators from the pressure regulation system, retaining only the essential mechanical components needed for pressure control. The simplified system uses a spring-loaded valve with bellows that directly sense and respond to pressure changes without any electrical intermediaries. This extraction resolves the contradiction by removing complex electrical subsystems while preserving the core pressure regulation function.
Solution Approach 2:
The mechanical pressure regulation system is self-acting and automatic, requiring no external power source or control signals. The spring-loaded valve automatically adjusts the discharge opening based on the balance between spring force and pressure force on the bellows, providing instantaneous response to pressure changes during clogging events. This self-service mechanism resolves the response time contradiction by eliminating dependence on external electrical control systems.

Function Achieved in This Case
This solution enables effective cleaning of conduits, reduces capillary damage, and allows for immediate pressure regulation, ensuring safer and more efficient operation by eliminating the need for electric actuators and their associated delays.
Implementation Method 1
a valve member (28) movable within the regulating valve (22) between a first position, in which the mouthpiece (12) is closed, and a second position, in which the mouthpiece (12) is open, and a spring (29) urging the valve member (28) towards the first position
Implementation Method 2
the force of the spring (29) and the surface area of the bellows (22) are calibrated so that the valve member (28) is moved into the second position when the pressure in the circuit (15) reaches a pre-established value
Implementation Method 3
a plurality of capillary tubes with permeable walls arranged approached and separated to each other and communicating with said inlet and discharge conduits, in order to separate the cleaned liquids being discharged outside through outlet conduits
