Plug Valves TRIZ Cases
- Energized Spring Seal for Floating Valve Seat
An energized spring seal pushes a resilient seat against a ball, eliminating leak paths between the valve body and seat under high pressure.
- Coupling With Shut-Off Device For In-Situ Gas Monitor Testing
A coupling integrates a shut-off device to isolate measuring ports for functional testing without removing the monitor from the gas line.
- Valve With Rotational Restriction Section Preventing Unintentional Closure
A valve with a rotational restriction section uses liquid pressure to maintain the open position of the valve element.
- Ball Valve Actuation with Sealed Encapsulation
A ball valve assembly uses a radially located drive mechanism and encapsulation to isolate the rotation device from process fluid.
- Anti-Stiction Spacer for Variable Displacement Pump
Grooved anti-stiction spacers offset static friction between pump components, maintaining stable rail pressure during cold weather operation.
- Rotary Ball Valve with Vent Hole for Gas Network Protection
A rotary ball valve integrates sealing rings and a vent hole to protect gas supply networks from contamination.
- Adaptive Facial Sealing Ring for Ball Valve Conduit Deflection
Axial translation of the floating closure member compensates for conduit deflection, preventing particle accumulation and leakage.
- Pin-fastening structure for valve shaft coaxiality
A pin-fastening structure aligns a valve shaft within a cylindrical portion using a connecting pin to restrict axial movement.
- Burst Disk Assembly with Tortuous Flow Path for Thrust Dispersion
A burst disk assembly vents excess pressure through a tortuous fluid flow path that disperses escaping gas in multiple directions.
- Dual Sealing Ball Valve Sheet Holder Compression
A sheet holder with a pressurizing retainer compresses an elastic sheet against a hollow ball, eliminating gaps from complex fitting processes.
- Isolatable Non-Slam Piston Check Valve for Double Block and Bleed
Merges block and check valves in a single standard space to reduce piping weight, fugitive emissions, and maintenance costs.
- Multi-Rotor Flow Control Valve for High-Capacity Engine Streams
Opposing dual rotors increase flow capacity while maintaining linear controllability, reducing pressure drop and actuator torque requirements.
- Emergency Inlet Valve for Hospital Vacuum Network Reliability
Segmented valves with emergency inlets maintain continuous vacuum distribution during central network failures.
