Electric Control Valve Signal Detection Plug for Accurate Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing issues in hydraulic pneumatic systems are inefficient, often leading to misjudgment and unnecessary disassembly of components, as they fail to accurately assess electric control signals, risking prolonged downtime and system contamination.
Innovation Solution
An electric control valve detection plug comprising an armature and insulating block, designed for easy installation and disassembly, allows for accurate measurement of electric control signals using a multimeter, reducing the risk of misjudgment by directly measuring the signal received by the valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the plug is unplugged and the electrical signal on the plug is measured separately, then the measurement can be performed, but there is a great possibility of misjudgment due to poor contact between the plug and the terminal of the valve
Solution Approach 1:
The detection plug serves as an intermediary device that maintains electrical connection with the valve terminal while providing accessible measurement points. It includes a connection end that connects to the valve terminal and a detection end with through-holes for multimeter probe access, thereby mediating between the sealed valve terminal and the measurement instrument without requiring plug disconnection
Solution Approach 2:
The detection plug is divided into distinct functional segments: a connection end for electrical connection to the valve terminal, an insulating block with through-holes for signal access, and a detection end for multimeter probe insertion. This segmentation allows each part to perform its specific function independently while maintaining overall measurement accuracy
2Productivity
If blind disassembly and replacement of hydraulic components is performed, then the troubleshooting can proceed, but it will prolong the downtime and waste effort
Solution Approach 1:
The detection plug enables preliminary measurement of the electric control signal at the valve terminal before any disassembly or component replacement is attempted. By measuring the signal directly at the source through the detection plug's through-holes, technicians can determine whether the valve coil is actually receiving power, preventing unnecessary disassembly of hydraulic components and reducing troubleshooting time
3Measurement precision
If the plug is unplugged for measurement, then the electrical signal can be measured, but the risk of polluting the hydraulic system exists
Solution Approach 1:
The detection plug acts as a sealed intermediary that provides access to electrical signals without requiring physical disconnection of the electrical plug from the valve terminal. The insulating block with through-holes allows multimeter probes to access measurement points while the plug remains connected and sealed, eliminating the risk of hydraulic fluid leakage or contamination that would result from unplugging
