Innovation Solution
A condensate drain utilizing an electromagnetic or magnetically acting drive device with a movable drive part inside the housing and a static drive part outside, separated by a fluid-tight wall, allowing for precise valve actuation and integration into digital systems, featuring a compact design and enhanced tightness, using a linear or axial flux motor for controlled fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a float condensate drain is used to drain condensate in steam-conveying plants, then the discharge function is provided as a function of fill level, but the device has a comparatively large volume and reduced responsiveness
Solution Approach 1:
The patent replaces the traditional float mechanism with an electromagnetic drive device that uses a magnetically actuatable component. This substitution eliminates the need for a large float while maintaining reliable condensate discharge functionality, directly resolving the contradiction between reliability and device volume.
Solution Approach 2:
The invention changes the actuation mechanism from passive float-based mechanical action to active electromagnetic actuation. This parameter change enables precise control of the valve body position while significantly reducing the volume required for the drive mechanism, addressing both the volume reduction and responsiveness improvement goals.
2Reliability
If a float condensate drain is used, then the discharge function is provided, but the responsiveness is firmly predefined due to design and mechanics
Solution Approach 1:
The electromagnetic drive device replaces the slow, predefined float mechanism with an electromagnet that can rapidly actuate the valve body. This substitution enables dynamic control and immediate response to control signals, directly improving responsiveness while maintaining the discharge function.
Solution Approach 2:
The invention introduces dynamic actuation capability through the electromagnetic drive, allowing the valve body to be moved rapidly between positions based on control signals. This dynamic control capability contrasts with the static, predefined responsiveness of float-based systems, directly addressing the speed/responsiveness requirement.
3Ease of operation
If a motorized drive device is used for moving a valve body in compressed air systems, then actuation is provided, but in plants with high steam pressures and steam temperatures, the required tightness and temperature resistance cannot be ensured
Solution Approach 1:
The patent replaces motorized drives with an electromagnetic actuation system that can be hermetically sealed. The electromagnetic drive device is designed to maintain tightness and temperature resistance in high-steam environments while providing reliable actuation, resolving the contradiction between ease of operation and reliability under extreme conditions.
Solution Approach 2:
The invention uses a magnetically actuatable component as an intermediary that can be positioned within the hermetically sealed housing. This intermediary allows electromagnetic actuation to be transmitted through the sealed barrier, enabling control functionality while maintaining the required tightness and temperature resistance against the surrounding steam environment.
4Ease of operation
If a motorized drive device is used, then valve actuation is provided, but integration into digitized control systems is challenging
Solution Approach 1:
The electromagnetic drive device with its magnetically actuatable component provides a control interface that can be directly integrated with digital control systems. The electromagnetic actuator responds to electrical control signals, enabling seamless integration into digitized control architectures and eliminating the complexity associated with adapting mechanical float or motorized drive systems to digital control.
