Bypass Valve Eliminating Clogging Through Dedicated Passageway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bypass valves in high-pressure washing systems require precise calibration of a through hole in the auxiliary shutter, which can lead to clogging issues and inadequate response to pressure changes, affecting the valve's ability to open and close correctly.
Innovation Solution
The proposed bypass valve eliminates the through hole by using a control element that moves between closed and open positions based on pressure differences between sections of the main conduit, facilitated by piloting conduits and a throttle element with an auxiliary shutter and sealing seat, allowing fluid communication through a passageway that replaces the need for a through hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a through hole is used in the auxiliary shutter to maintain fluid communication, then the bypass conduit can open reliably, but the through hole becomes prone to clogging and requires very accurate calibration
Solution Approach 1:
The invention extracts and eliminates the through hole from the auxiliary shutter by replacing it with a dedicated passageway (34) formed between the control element (31) and the housing (32). This passageway maintains fluid communication between the first and second sections when the bypass conduit is open, without requiring a small calibrated hole that is prone to clogging. The control element is provided with an outer surface defining the passageway in collaboration with the housing, thereby removing the problematic through hole while preserving its functional purpose.
2Speed
If the through hole diameter is made very small to ensure rapid pressure response, then the pressure peak forms correctly, but the through hole clogs frequently preventing bypass opening
Solution Approach 1:
The invention introduces a dedicated passageway (34) as an intermediary fluid communication path between the first and second sections of the main conduit. This passageway, formed by the collaboration of the control element's outer surface and the housing, serves as a reliable alternative to the small through hole. It maintains adequate fluid communication during bypass operation without being susceptible to clogging, while still allowing rapid pressure response when the bypass conduit opens.
3Reliability
If the through hole diameter is increased to prevent clogging, then clogging frequency decreases, but the pressure peak formation becomes inadequate
Solution Approach 1:
The invention segments the fluid communication path into two distinct functional zones: the bypass conduit (30) controlled by the control element (31) for pressure-regulated flow diversion, and the dedicated passageway (34) for maintaining auxiliary fluid communication. This segmentation allows the bypass conduit to form adequate pressure peaks through its controlled opening mechanism, while the separate passageway prevents clogging issues without interfering with pressure dynamics.
4Reliability
If a control element with passageway is used instead of a through hole, then clogging is prevented, but the device complexity increases
Solution Approach 1:
The invention merges the control element (31) with the passageway (34) formation, where the control element's outer surface directly defines the passageway in collaboration with the housing (32). This integration eliminates the need for separate components and reduces overall device complexity despite the enhanced functionality. The control element simultaneously performs its primary control function and creates the clog-resistant passageway, thereby improving reliability without proportionally increasing complexity.
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
This design enhances the reliability and responsiveness of the bypass valve by preventing clogging and ensuring accurate pressure management, allowing for efficient fluid discharge and recirculation without the need for precise calibration of a small diameter hole.
Implementation Method 1
A control element (31) mobile between a closed position, at which it closes the bypass conduit (30), and an open position, at which it opens the bypass conduit, allowing the total or partial outflow of the fluid towards a discharge. The control element (31) is mobile between its open and closed positions by means of the pressures present in the first and second sections (11, 12) of the main conduit (10).
Implementation Method 2
The throttle element (40) is structured to produce a load loss which depends on the fluid flow rate in transit along the main conduit (10).
