Valve Actuator Self-Identification for Accurate Valve Parameterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The parameterization of valve systems in automation technology is complex and prone to errors due to the need for manual intervention, making it difficult to accurately identify and configure different valve designs.
Innovation Solution
An operating method that automatically identifies the design type of a valve by detecting and storing absolute positions of the actuating shaft, using an algorithm to distinguish between stroke-actuated and pivot-actuated valves, and parameterizing the valve system based on these identifications, thereby simplifying the commissioning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual parameterization and assembly of valve systems is performed, then flexibility in handling different valve designs is achieved, but error rate increases and commissioning time is extended
Solution Approach 1:
The valve system performs self-identification by automatically detecting its own design type through algorithmic evaluation of actuating characteristics, eliminating the need for manual parameterization and reducing commissioning time while maintaining high accuracy
2Adaptability or versatility
If manual intervention is used for valve system configuration, then complex valve designs can be handled, but error-prone operations occur
Solution Approach 1:
The system automatically adapts to different valve design types by detecting characteristic parameters during actuation and dynamically adjusting configuration settings, ensuring accurate setup across diverse valve types without manual intervention
3Measurement precision
If comprehensive parameterization is performed manually, then precise valve configuration is achieved, but assembly complexity increases
Solution Approach 1:
The complex parameterization process is extracted and replaced by an automated identification algorithm that detects valve characteristics and determines optimal parameters automatically, maintaining precision while eliminating manual configuration complexity
