Gas Pressure Regulator Layout for Low-Force Inlet Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas regulators require a larger driving force to operate due to the deformation of the gas chamber diaphragm, which increases energy consumption and makes low-voltage startup challenging.
Innovation Solution
The pressure regulating device is designed with the pressure regulating component and transmission mechanism located on opposite sides of the gas chamber diaphragm, allowing the transmission mechanism to operate independently of the diaphragm's resistance. This design reduces the driving force required for operation, enabling low-voltage startup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pressure regulating component and transmission mechanism are located at the same side of the gas chamber diaphragm, then the gas path can be closed off, but the transmission mechanism needs to overcome resistance from the deforming diaphragm, requiring larger driving force and more energy
Solution Approach 1:
The device is divided into two separate sides: the pressure regulating component is located on one side of the gas chamber diaphragm while the transmission mechanism is located on the other side. This segmentation allows the transmission mechanism to operate independently without being affected by diaphragm deformation resistance, thereby reducing energy consumption while maintaining the gas path closure function.
2Reliability
If the transmission mechanism drives the lever to rotate to block the inlet channel, then the gas path can be closed off, but the gas chamber diaphragm deforms with the transmission mechanism, increasing the driving force required
Solution Approach 1:
The transmission mechanism is extracted and positioned on the opposite side of the gas chamber diaphragm from the pressure regulating component. This extraction eliminates the interference of diaphragm deformation on the transmission mechanism's operation, allowing the lever to be driven with smaller force to achieve reliable gas leakage shutdown.
3Reliability
If the transmission mechanism provides larger driving force to overcome diaphragm resistance, then the lever can be driven to block the inlet channel, but the gas regulator needs more energy to operate
Solution Approach 1:
By segmenting the device into two independent sides with the transmission mechanism on the opposite side from the pressure regulating component, the system eliminates the need for high operating power. The transmission mechanism can drive the lever to seal the inlet channel with minimal power consumption since it does not need to overcome diaphragm deformation resistance.
