Diaphragm Valves TRIZ Cases
- Beverage Maker Membrane Valve Design to Reduce Calcification Sticking
See how a flexible membrane valve with ring-shaped outlet geometry prevents limestone adherence
- Diaphragm Valve Pressure Regulation for Stable Fuel Discharge
Spring-loaded diaphragms regulate outlet pressure to keep fuel discharge stable in portable gas burners across fuel types and low temperatures.
- Steam Cleaner Return Valve to Stop Residual Steam Ejection
A return valve redirects residual boiler steam to the water tank, stopping post-trigger steam ejection while keeping the boiler at atmospheric pressure.
- Pinch-Sleeve Beverage Valve for Precise Tea Mixing Control
A pinch member and flexible sleeve regulate hot water and concentrate flow for consistent tea strength from one dispenser.
- Levelling Sleeve Stop Design to Prevent Spindle Thread Exposure
A sleeve stop surface and spindle stop item limit adjustment travel, keeping threads covered for hygienic levelling feet in approved environments.
- Variable Flow Heating Control for Room Load and Cavitation
A controller adjusts total heating flow by room load and valve status, cutting fuel waste and cavitation noise when rooms are closed.
- Compression-Modulated Cushion Valve for Automatic Pressure Control
A collapsible valve with compression members automatically regulates cushion fluid flow, maintaining support pressure without manual adjustment.
- Dual-Fluid Snow Gun Spray Circuit for Gravity Draining
A valve-controlled dual-fluid spray circuit uses compressed air and gravity draining to prevent water stagnation, freezing damage, and extra frost protection.
- Stepper-Driven Pinch Valve for Hygienic Beverage Flow Control
A stepper-driven pinch valve controls coffee and milk flow without constant energization, cutting contamination risk, weight, and valve cost.
- Rotatable Pinch Valve Assembly for Easy Tube Change and Cleaning
A rotatable pinch bar with spring and solenoid actuation simplifies tube installation, removal, and cleaning while maintaining stable fluid shutoff.
- Conical Relief Valve for Inverted Liquid Soap Containers
A conical valve body and flexible diaphragm admit air only at low pressure, preserving soap flow and sealing when the container is inverted.
- Refrigerator Airway Seal Membrane for Door Icemaker Cooling
A slit membrane seal opens only when the refrigerator door closes, preserving chilled airflow to the door icemaker and blocking condensation ice buildup.
- Refill Unit Relief Valve Layout for Inverted Liquid Flow
A shrouded flexible diaphragm relief valve admits air at low pressure while keeping air out of the liquid outlet in inverted refill units.
- Composite Cushion Valve Assembly for Automatic Pressure Modulation
A collapsible elongate valve member automatically modulates cushion fluid flow and pressure, reducing manual adjustment for consistent support.
- Dual-Nozzle Mop Sprayer With Rotating Collar Pattern Switching
A rotating collar pinches one of two supply tubes to switch mop spray patterns reliably without complex adjustable nozzles or extra lever travel.
