Lift Valve TRIZ Cases

A filling connector uses a dual-position dust valve to guide gas flow and actuate the isolation mechanism.

An annular groove in the valve seat deforms under pressure to accommodate disc deflection and prevent leakage.

Thin arcuate disc design increases open area by 24.3% to accelerate unloading speed and reduce noise in tank trailer operations.

Segmented cartridges and a removable cap resolve diaphragm replacement challenges while enabling reliable leakage monitoring without hollowing the valve stem.

Segmented seals with matched material hardness absorb positional deviations, reducing manufacturing effort while maintaining low leakage rates.

A spherical sealing member engages the valve disk to provide a fluid-tight seal in harsh environments.

Pretensioned snap-in locking elements engage recesses on the throttle body to prevent axial mobility and unscrewing of the valve stem.

Symmetric drain-proof ring simplifies manufacturing and allows dirt removal by rotation while maintaining tight sealing.

A valve apparatus uses a bactericidal fluid reservoir to form a germ barrier between seal arrangements.

A ring retainer restrains radial expansion of sealing rings in a butterfly valve, preventing friction and wear against the bore.

Segmented hollow ceramic balls withstand fracturing pressure while breaking into flushable fragments to resolve removal difficulties.

Cone-shaped spindle tips reduce erosion in high-pressure valves by dissipating flow energy through controlled gaps, extending wear cycles beyond 5000.

Polygon plug-in connection transmits torque while eliminating notch effect stress concentrations.
