Equalizing Valves TRIZ Cases

A low-pressure-side support is destroyed by an actuator so a bursting disk opens safely under pressure without high-side actuation.

Built-in bosses in the rupture sheet replace manual spacers, ensuring uniform seal compression and preserving explosion panel integrity.

A soft insert lets a watch safety valve use ceramic or sapphire heads without pressing or welding, preserving gas release and watertightness.

A parallel membrane and pressure-relief valve boosts pressure equalization in tight housing space while enabling emergency degassing.

Dual spring-biased shutoff elements and a snap-fit clasp let one valve stop excess fluid flow in either direction and close further under heat.

A series pressure-limiting hydraulic circuit creates two colter pressures from one supply to offset travel-lane soil compaction and keep spreading depth uniform.

Integrated embossments in the rupture sheet replace removable spacers to balance gasket compression and prevent sealing damage.

A shape memory preload offsets spring stiffness loss at high temperature, keeping pressure relief valve cracking pressure more stable.

An enlarged space around the relief valve seat redirects fuel flow to suppress cavitation erosion and improve fuel pump durability.

A stepped guided seat constrains valve seat motion under high pressure, reducing wear and extending relief valve service life.

A shallow taper and mounting support pre-compress the rupture disc to limit tensile stress, cut debris size, and keep wellbore sealing pressure-competent.

Screw interfaces are moved outside the valve chamber to stop metal powder from contaminating fluid flow while maintaining sealing.

A tapered disc and inner-outer sled mechanism hold high wellbore pressure, then trigger controlled release with less debris and no plug drill-out.

A sealed valve housing removes access openings that could block the spring or valve body, preserving reliable pressure relief under set pressure.

A buoyancy-driven float ball valve vents gas during filling, admits gas during draining, and seals the chamber when liquid rises.

An expanding nipple and reducing tee lower fluid velocity in a back pressure regulator, cutting internal wear while keeping standard pipe connections.

An integrated inlet-outlet manifold pairs relief valves to simplify cryogenic fluid routing, cut leak paths, and ease maintenance.

A multi-face cam lets a spring-biased ball valve make precise fuel pressure changes in place, avoiding regulator removal and recalibration.

Adjustable balancing valves equalize divider block outlet pressures to stop short stroking and maintain accurate compressor lubrication.

A sliding block and magnetic adjusting block balance seal-chamber pressure during coolant gasification to prevent server deformation and damage.

An annular groove and plunger-side relief valve layout shift cavitation away from the seat member to reduce erosion and preserve sealing.

Two spring-biased shutoff elements let one valve stop excess fluid flow in either direction, easing installation and improving network safety.

A shared spare piping run with dual pressure pilots cuts surge-relief redundancy while protecting pipelines from pressure transients.

A rigid vent disc and flexible flap relieve bottle vacuum at low suction while limiting leakage and reducing vent wear over time.

A spring-biased poppet valve limits high-pressure gas flow spikes, stabilizing mass flow during fast transient pressure changes.

A threaded spindle-seat retainer and shroud huddling effect help small high-pressure relief valves reduce leakage and simmering.

A single suction valve and shared flame arrester cut condensation and complexity while maintaining reliable tank pressure equalization.

A clawed thermoplastic rear cover and pre-measured springs remove screws and adjustment pieces while maintaining precise PRV pressure control.

A protrusion with an internal passage equalizes pressure across the valve element to suppress hunting and stabilize relief valve behavior.

A resilient flange lets the disc seat surface pivot and conform to the valve seat, maintaining sealing at low set pressures.

An inner and outer sled rupture disc releases buoyant fluid without drilling, maintaining high pressure competency while minimizing debris.

Pre-compressing the leaf spring adds initial load, cutting reciprocation load swings and improving pressure reducing valve durability.

Multiple pressure transmitters with voting logic keep a pressure relief valve from false opening or closure when one sensor fails.

Gravity-held ball seats replace wear-prone valve parts, enabling durable fuel tank pressure and vacuum relief with easier field servicing.

A spring-biased flow plate uses pressure-activated openings to adapt fluid flow across changing temperature and pressure without extra valves.

A piston pod uses bleed air and a bypass mix to deliver reservoir fluid reliably despite acceleration and orientation changes.

End-to-end coupled PRV stages relieve high internal enclosure pressure from leaks or off-gassing while allowing adjustable cracking pressure.

A stiff plastic gasket and bridge-like support keep an overpressure valve sealed under high pressure, preventing gasket blowout and gas leakage.

An insert-based watch valve uses screwing and gluing to mount a ceramic head, enabling gas release under decompression without welding.

A pendulum inertial body triggers rapid valve closure under acceleration while keeping normal gas flow resistance low.

A heated auxiliary drain with self-draining and flow restriction removes condensate, prevents freezing, and avoids false tripping in dry pipe sprinklers.

Preloaded springs keep the plug body sealed to the valve seat after seat disc deformation, preserving cryogenic shutoff during fire exposure.

A downstream flow-diverting element relieves shutter-face overpressure, enabling higher gas flow without sacrificing pressure control precision.

A staged breakaway connection releases gas before valve damage, helping gas meter housings avoid uncontrolled overpressure leaks.

An oscillating inertial mass closes the valve under lateral acceleration, stopping fluid discharge with a simpler, more robust mechanism.

A sealed bushing isolates the piston from bore cooling and friction, helping SCBA first-stage reducers avoid jamming across temperatures.

An externally adjustable stop member changes poppet preload, letting users set closing pressure without dismantling the regulator.

A sealed bushing separates the piston from the bore to prevent adiabatic-cooling jamming in SCBA first-stage pressure reducers.

A coaxial valve assembly combines outlet closing and pressure relief functions to simplify direct-injection fuel pump mounting and cut parts.

By placing the rupture disk ahead of the flame arrester, this case cuts vent size, blocks contamination, and preserves pressure relief.
