Spindle Sealings TRIZ Cases
- Flow Control Valve Backlash Elimination
A flow control valve uses a spring urging member to bias threaded connections, eliminating mechanical backlash between the motor and valving element.
- Valve Stem O-Ring Retainer for Leakage Prevention
A disk projection on the valve stem guides the O-ring back to its seated position, preventing fluid leakage caused by misalignment.
- Needle Valve Flexible Membrane Sealing Two-Component Paint
Flexible membrane isolates pneumatic drive from two-component paint curing agent escape and adhesion.
- Regulating Valve Gland Packing Thermal Expansion Control
Adapter packings suppress yarn packing deformation from thermal cycles, maintaining seal stability without complex spring mechanisms.
- Force-Balanced Gas Valve with Multi-Seal Disk
A gas valve balances pressure via connecting channels on the disk, enabling rapid high-volume metering despite fluctuating inlet pressures.
- Vacuum Angle Valve Sliding-Block Guide Drive
Automated motorized drive replaces manual sliding-block guides to eliminate contamination risks while maintaining precise vacuum-tight angle valve operation.
- Electric Valve Partition Plate for Fluid Leakage Safety
A partition plate divides an electric valve housing into separate fluid and actuating spaces to isolate sensitive components.
- Faucet Safety Lock with Latch and Primary Element
A faucet handle integrates a latch and primary lock element to enforce a three-step dispensing sequence.
- Valve Shaft Seal with Metal Support Form-Fit
Metal support structure undergoes plastic deformation to lock onto guide element, preventing seal displacement at high pressures.
- Faucet Valve Safety Handle with Rotatable Insert Member
A faucet valve safety handle uses a rotatable insert member to control liquid flow through the valve chamber.
- Chamber Bellows Coating for Corrosion Control
Coatings like PTFE and DLC shield chamber bellows from corrosive gases, preventing particle contamination.
- One-way Valve for Hybrid Vehicle Battery Storage Basin
A one-way valve with a diaphragm expels assembly liquids from a hybrid vehicle storage basin.
- Subsea Valve Magnetic Coupling Eliminates Leakage
A sealed actuator housing with magnetic isolation prevents high-pressure fluid leakage into control systems.
- Suck Back Valve Synchronization Prevents Water Hammer
A control unit synchronizes pneumatic valve closing operations to enhance the suck back function.
- Gas Inlet Valve Bellows Piston Corrosive Gas Isolation
Segmented stainless steel and aluminum components with dual seals protect hardware from chlorine degradation.
- Corrugated Elastomeric Ring Diaphragm Stress Distribution
An elastomeric ring with a matching profile distributes stress across a corrugated diaphragm, preventing premature failure from localized concentrations.
- Dual Packing Chamber Valve Seal with Leak Detection
Segmented packing chambers and thermal monitoring prevent environmental leaks while allowing component replacement without valve removal.
