Functional Valve Types TRIZ Cases
- Aircraft Air Mixer With Integrated Non-Return Valve for Low Pressure Loss
Integrating the non-return valve into the aircraft air mixer cuts weight and pressure loss while helping prevent icing and maintain cabin pressure.
- Self-Sealing Diaphragm Valve for Inflatable Pressure Control
A resilient diaphragm and valve seat use pressure differential to self-seal and open on demand, improving inflatable flow and pressure control.
- Steam Oven Drain Valve Layout for Power-Free Water Removal
Automatic drain valves use pressure drop and gravity to empty aircraft steam oven lines without power, preventing freezing damage and stagnant water.
- Heat Exchanger Valve Control Using Dual Temperature Sensing
Dual temperature sensing detects valve closing conditions in heat exchangers, improving position control while cutting actuator energy use.
- Steam Distillation Extraction for Safer Medicinal Liquids
Alternating steam distillation and immersion extracts volatile and soluble compounds while reducing harmful residues and manual errors.
- Condensate Leak Switch Using a Dissolvable Biocide Tablet
A dissolvable biocide tablet triggers condensate leak shutdown and alarms while limiting algae growth and simplifying testing.
- Vacuum Pump Cabinet With Removable Panels for Noise and Cooling
Removable top and side panels cut vacuum pump noise while preserving cooling, maintenance access, and lubricant drainage.
- Spray Fill Pressure Control for Low-Water Washer Rinsing
A pressure-threshold spray fill controls rinse flow in washing machines, cutting water use while avoiding recirculation hardware.
- Heat Pump Hot-Water Tank Circulation for Scale Prevention
Multiple water supply paths and water quality adjustment limit scale in high-temperature heat pump hot-water tanks and circulation pipes.
