Spindle Sealings TRIZ Cases
- Fixed Heater Block in Angle Valve for Semiconductor Manufacturing
A fixed heater block replaces coil-shaped sheath heaters in angle valves, preventing particle precipitation and component damage during actuator operation.
- Seal Life Estimation Using Cycle and Stress Monitoring
A processor estimates seal useful life by tracking operational cycles and mechanical stresses during fluid control.
- Regulating Valve Gland Seal with Uniform Compression Packing Follower
Concentric packing follower ensures uniform compression loads on gland packings, preventing fluid leakage and reducing wear during thermal cycles.
- Curved Valve Disk Reduces Closing Force in Vacuum Seals
Elastic deformation of a curved valve disk reduces closing force by half while compensating for geometric inaccuracies in high vacuum seals.
- Live-Loading Packing Apparatus with Force Indication Scale
A live-loading packing system maintains consistent pressure via Belleville springs while a calibrated piston rod provides visual force indication.
- High Temperature Valve Shaft Seal Using Metal Seals
Metal seal members and bushing prevent fluid leakage while accommodating thermal expansion in high temperature engine breathing valves.
- Conditioned Valve Stem Surface for Graphite Packing Lubrication
A valve stem features a conditioned surface that holds lubricating material to reduce friction against graphite packing rings.
- Hydraulic Stroke Translator With Metal Bellows Seal
Metal bellows seal hydraulic volumes in a stroke translator, eliminating piston guide wear and hydrogen diffusion.
- Bottom-Loaded Packing Assembly for Control Valve Stem Sealing
Belleville disk springs in a bottom-loaded packing assembly track process pressure to reduce friction and wear on the valve stem.
