Equalizing Valves TRIZ Cases

An activation-rod shutoff valve closes inside a breakaway wet barrel hydrant to stop collision-triggered water discharge without excavation.

Split inner and outer gas passages disperse hydrogen pressure, reduce moisture freezing, and keep the valve body operating properly.

A movable orifice plate limits steam escape during line breaks while keeping normal pressure drop and moisture carryover low.

A form-fitted carbon retainer secures a graphite vacuum support without adhesives, enabling clean, predictable pressure relief at high temperature.

A removable excess flow valve lets gas service lines be re-rated for changing demand without excavation, pipe replacement, or supply interruption.

Shared inlet and outlet manifolds route cryogenic tank pressure through parallel relief valves, cutting piping complexity and easing maintenance.

An elastically deformable stainless steel plate limits bursting disc opening to under 90° for reliable pressure wave and flame direction.

A controller adjusts chamber pressure with a compressor and vent valve to track demand changes while limiting pressure transients.

Grooves on the spring seat or piston let the PRVC diaphragm key into place, preventing rupture under excess pressure without changing calibration.

An insert element moves the biasing element out of the flow path, preserving smooth flow while maintaining sensitive pressure control.

A self-contained hydraulic piston and spring layout enables fast surge opening and oil-dampened reclosure without an external reservoir.

An inductive sensor tracks plunger movement in a PSV discharge pipe to give reliable visual and remote discharge alerts under vibration.

A ball-and-diaphragm valve relieves both positive and negative reservoir pressure in a compact medical design that protects flow and sealing.

Chamfered tines and a fixed stop create different opening and closing pressures, preventing valve oscillation and enabling adjustable trigger pressure.

Primary and secondary communication holes circulate branched fuel in the cover space, limiting stagnation, corrosion, and component wear.

An integral pin cage, protective sleeve, and energy absorber improve buckling pin valve alignment, force transfer, and activation accuracy.

Coaxial dual springs and an integrated valve body let draft beer kegs maintain stable outlet pressure while adapting to changing pressure requirements.

High-frequency laser incisions added after welding keep rupture discs precisely calibrated while preserving sealing tightness and reliable burst behavior.

A shared spare piping run and dual pilots vent surge pressure across parallel lines, cutting redundancy, cost, and maintenance.

Calibrated burst panels in a flexible aircraft barrier vent at set pressure thresholds, preserving smoke isolation without heavy framing.

Relief areas in a rupture disc support member absorb displaced gasket material, improving sealing and keeping burst pressure consistent.

A portable pump, valve, and flexible conduit enable continuous machine fluid evacuation and refill while supporting maintenance data collection.

A portable conduit, pump, and check-valve layout relocate fluid servicing from hard-to-reach drain ports, cutting downtime and spill risk.

A dedicated damping chamber and calibrated inlet orifice raise valve damping, cut oscillations, and avoid cavitation across the stroke.

A transverse valve slide layout in the connector plate expands pivot angle range while keeping axial piston machines compact and low in height.

A valve element with an internal oil passage replaces extra downstream bypass routing, cutting oil cooler size, complexity, and cost.

A lighter first spool and series elastic members extend differential pressure range while improving stable low-pressure detection.

A separated seal layout vents leaked gas while blocking liquid ingress, preventing pressure buildup that can damage the valve.

Downstream pressure routed through a hollow valve plug balances fluid forces, reducing inlet decay and valve seat damage in pressure regulators.

Magnetic sensing tracks pressure relief valve opening frequency and duration, improving maintenance data and system safety.

Multiple chambers, a piston, and an orifice sleeve stabilize turbulent high-pressure discharge for consistent fire-extinguishing line pressure.

External propellant gas and a rupture disc stabilize fire suppressant discharge pressure, enabling full expulsion with smaller, lighter containers.

A through-bore pressure-limiting valve uses low-pressure fuel flow to flush debris, protecting the pressure chamber from contamination.

A two-spring cam valve lets dive watches vent helium at controlled pressure while preserving water resistance and avoiding crystal damage.

A friction ring lets a watch valve head be rotated into precise logo alignment while preserving sealing and spring-loaded pressure regulation.
