Pressure Relieving Devices On Sealing Faces TRIZ Cases

A single elastic member and return pusher simplify female fluid connector locking, cutting size, wear, and manual effort.

An axial through-hole plug and side-opening piston increase fuel discharge area without adding valve complexity or cost.

An auxiliary valve equalizes pressure across a hydrant main valve before opening, cutting operating torque and easing manual operation.

Sintered superhard rings in choke cage conduits cut high-pressure wear and erosion, extending choke valve life without full-ring cost.

Balance ports on the valve plug equalize pressure to cut peak stem force and improve pressure recovery through choked flow.

A two-contact valve seat and tubular disc cut hydrostatic opening force while maintaining metal sealing in low-temperature liquefied gas tanks.

A thermally active hard stop maintains plug gap at high temperatures, limiting over-travel, seal wear, and valve trim stress.

Pressure relief slots in the mixing chamber stabilize water temperature and flow with only slight handle rotation.

Vortex generators and a honeycomb flow element cut flow separation, cavitation, noise, and weight while maintaining valve pressure drop.

A tethered balance member cuts stem thrust and gate drag, enabling smaller actuators while preserving pressure-triggered safety valve closure.

A pressure-balanced trim assembly uses a low-friction flow restrictor and vented seal volume to maintain Class V sealing with lower actuator thrust.
