Plug Valves TRIZ Cases

An air delivery device applies fluid pressure pulses to the mouth cavity using controlled airflow occlusion and vibration.

Hydraulic lifting separates the plug from its seat before rotation, eliminating mechanical wear and ensuring reliable operation under high thermal loads.

Cover employs segmented posts and hook portions to fixate faucets securely while allowing easy detachment for maintenance.

Dual chamber orifice fitting uses an eccentric plug member to form a fluid tight seal without grease.

Segmented wedge seals and PTFE liners prevent lubricant contamination while enabling in-field O-ring replacement.

Axial spring preload on a curved sealing ring ensures uniform contact pressure, resolving leakage risks from non-uniform force distribution.

A valve assembly with a rotatable shutter adjusts cooling liquid flow rate based on angular position.

Lattice insert parts calm turbulent water flow to reduce noise generated by plastic hydro-block resonances.

Merges two sealing portions into one unit to simplify mounting and prevent fluid leakage from the tube connection.

A ball valve design with a drain opening and metallic thread allows controlled depressurization without additional fittings.

A quick change check valve system uses adapters and a collar mechanism to enable tool-free removal and installation of check valves.

Segmentation and nesting principles enable DIY installation of remote control on manual valves without disrupting water flow.

A valve uses a cam device to vary spacing between the sealing member and movable member during rotation.

Spring seats interlock to apply axial force, preventing weight-induced misalignment and leakage in vertical rotary valves.

A cylinder valve assembly integrates fill-dispense, on-off control, and overpressure relief subsystems within a single compact body.

A rotary fluid selection valve merges multiple channels into a single assembly to simplify parallel sample handling.

A hollow ball valve uses a thermoplastic outer layer on a metal core to reduce friction and wear.

Rotating shielding plates replace solenoid plungers to boost response rates and enable high-speed pickup of heavy paper sheets.

A ball valve design distributes pressure drops across multiple components to reduce shear-induced noise and cavitation.

A top-mounted reverse osmosis faucet assembly uses a toggle bolt for above-counter installation.

A multi-shutoff valve device uses steam barriers to maintain aseptic separation between fluid conduits.

An ultrasonic shut-off valve measures flow rate without moving parts, eliminating mechanical complexity and reducing pressure loss in building installations.

Segmenting the plug body and trunnion via a keyed dovetail fit enables distinct material choices while maintaining structural integrity.

Segmented flow channels in the control plate reduce device complexity while enabling precise fluid rate adjustment.

A rotatable valve body uses a spherical seal to regulate coolant flow in electric vehicle battery packs.

An angled partition in a T-shaped passage divides viscous and fluid components of non-Newtonian liquids to resolve asymmetrical distribution defects.
