Plug Valves TRIZ Cases
- Rotary Valve with Grooved Rotor for Flow Path Management
A rotary valve uses internal grooves to direct fluid flow, reducing tubing complexity in liquid chromatography systems.
- Modular Throttling Valve Trim for Cavitation and Freezing
Segmented multi-port disc trims stage pressure drops to prevent Joule-Thomson freezing while direct actuator mounting eliminates recalibration downtime.
- SMA Valve Actuator with Shearable Nipple
A shape memory alloy valve actuator drives a shearable nipple via a hammer component to open fluid passages in aerospace systems.
- Dynamic Ball Valve Seal Compensating for Tolerances
A floating seal member adjusts position on the valve surface to maintain contact.
- Butterfly Valve Flow Straightening Ribs
Tapered valve element with inclined ribs straightens airflow, reducing turbulence and pressure loss to boost engine gas mileage.
- Rotary Valve Elastomeric Seal for Flow Control
An elastomeric seal on a rigid obturator reduces friction during rotation, resolving the trade-off between accurate flow regulation and internal leakage.
- Bellows Fluid End Seal Wear Reduction
An incompressible fluid-filled bellows equalizes pressure around a plunger, reducing seal wear and leakage in high-pressure fracturing pumps.
- Security Blow-Out-Proof Valve Assembly Stem Locking
A security blow-out-proof valve assembly uses a rotating T-head to actuate the internal ball valve member.
- Rotary Shear Valve Polymer Insert for High Pressure Sealing
A polymer insert device press-fits into a rotor groove to create a fluid-tight seal, supporting pressures up to 25 Kpsi and exceeding 50K cycles.
- Side-Load Nozzle Insert with Ball Valve for Irrigation
A side-load nozzle insert uses a ball valve and spring arms to rotate between operating positions.
- Multi-Stage Turbocharger Exhaust Flow Control
Rotary valve modulates exhaust gas flow through primary and bypass paths in a multi-stage turbocharger system.
- O-ring Lubrication System for Pressure Regulators
An annular groove on the piston creates a reservoir that enables lubricant replenishment without disassembly, extending operational life.
- Bellows Energized Seal Assembly for Rotary Control Valves
A bellows energized seal assembly biases a main seal axially within a seal body using elastic deformation.
- Multi-blade Dosing Valve Independent Vibrator Segmentation
Segmenting vibration sources into independent units per shaft concentrates energy on blades, preventing material bridges and reducing noise.
- Flexible Seal Insert for Rotary Valve Leakage Control
Segmented seal carrier rings with elastic portions absorb thermal expansion and vibration, ensuring reliable sealing under fluctuating conditions.
- Valve Knob Positioning via Resilient Member and Notches
A valve knob engages notches with a resilient member to provide auditory feedback, eliminating the need for external tools during operation.
