Fluid Control Valve Position Output Zeroing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid control valves with position sensors face usability issues due to the presence of a dead zone and varying opening start positions, leading to misunderstandings about valve operation, potentially indicating clogging or failure.
Innovation Solution
The fluid control valve sets the opening start position to zero irrespective of positional information, using a position output part to correct and display this position, eliminating user misunderstandings and individual differences in valve performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the position sensor output is used directly to indicate valve body position, then the measurement precision is maintained, but the ease of operation deteriorates due to user misunderstanding about the opening start position
Solution Approach 1:
The patent introduces an intermediary processing step between the position sensor and the user interface. The position output part processes the raw position sensor data to calculate and output the opening start position, which serves as a mediator that translates complex sensor readings into meaningful operational information for the user, thereby resolving the contradiction between maintaining measurement precision and improving ease of operation
Solution Approach 2:
The system implements feedback by continuously monitoring the position sensor output and providing processed position information back to the user through the position output part. This feedback loop allows users to understand the actual valve position relative to the opening start position, eliminating confusion while preserving the accuracy of the underlying sensor measurements
2Adaptability or versatility
If the opening start position varies between individual valves, then the adaptability to different valve characteristics is maintained, but the manufacturing precision deteriorates due to inconsistency in valve performance
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing the opening start position for each individual valve through the position output part. This pre-processing of position data allows the system to compensate for manufacturing variations before they affect operation, enabling each valve to be adapted to its specific characteristics while maintaining consistent operational performance across all valves
Solution Approach 2:
The system changes the reference parameter for position measurement from a fixed absolute position to a relative position based on the opening start position. By adjusting the reference frame to account for individual valve variations, the system maintains manufacturing precision while accommodating differences in opening start positions across individual valves

AI summary
The present invention provides a fluid control valve that improves usability by eliminating misunderstanding of a user. The fluid control valve includes a valve seat, a valve body disposed to be approachable to and separable from the valve seat, an actuator configured to move the valve body in an approaching or separating direction, a positional information detection part configured to detect a value corresponding to a relative position of the valve body with respect to the valve seat, and a position output part configured to set, irrespective of positional information acquired by the positional information detection part at an opening start position of the valve body, the opening start position to position zero.
