Gas Valve Coil Voltage Control for Closed State Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas valve devices lack the ability to independently check and ensure the closed state of valve units, leading to potential malfunctions and safety issues in heating systems, particularly in scenarios where fluid flow control is critical.
Innovation Solution
A gas valve device with a control unit that supplies different electrical voltages to control valve units, where a second electrical voltage closes the second valve unit, and a sensor unit detects fluid presence to verify the closed state, allowing for targeted troubleshooting and prevention of system malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single coil controls both valve units with a single voltage state, then the device complexity is reduced, but the ability to independently check and verify the closed state of valve units is lost
Solution Approach 1:
The control unit performs a preliminary check by applying a second voltage state to close the second valve unit before the main operation. This preliminary action allows verification of valve functionality and closed state through the sensor unit, ensuring reliability before normal operation with the first voltage state.
Solution Approach 2:
The sensor unit provides feedback about fluid presence in the fluid line. By combining this feedback with the second voltage state application, the control unit can verify whether the second valve unit properly closes the fluid line, enabling independent verification of valve unit functionality.
2Adaptability or versatility
If multiple voltage states are used to control valve units independently, then the reliability and troubleshooting capability are improved, but the control system complexity increases
Solution Approach 1:
The control unit applies the second voltage state as a preliminary diagnostic action to close only the second valve unit. This allows isolated testing of the second valve unit's functionality and closed state verification through the sensor unit, enhancing troubleshooting capability without requiring complex additional hardware.

AI summary
The invention relates to a gas valve device comprising at least one first valve unit (12) and at least one second valve unit (14), which are designed to at least substantially open and/or close a fluid line, with at least one coil (18) for controlling at least the first valve unit (12), and with a control unit designed to supply the coil (18) for controlling the valve units (12, 14) with at least one electrical voltage. It is proposed that the control unit be designed to supply the coil (18) with at least one first electrical voltage in at least one operating state and with at least one second electrical voltage, both of which are different from zero, in at least one second operating state.
