Plug Valves TRIZ Cases

A disposable dental valve uses a rotatable sealing body to control fluid flow and reduce noise.

Segmented fin members rotate to discharge accumulated dust while maintaining continuous air lock closure against intake tract vacuum.

A double-piston-effect valve uses embedded O-rings and hydrostatic force to achieve bidirectional sealing within a compact piston ring structure.

An inset collar mounts the valve body lower to resolve handle accessibility issues, while an o-ring ensures a reliable watertight seal.

A resilient end stop arrangement compresses under excessive loads to prevent rigid plastic breakage in coolant control valves.

A plastic radiator valve integrates the body and adapter into a single monobloc component via injection molding.

Rotating connecting unit couples valve body to deck fixing unit while switch unit blocks water supply hole during decoupling.

Contoured bore creates low-pressure region that draws abrasive particles away from sealing surfaces, preventing premature wear and leakage.

A shut-off valve uses a spherical segment body and hollow spindle to enable complete fluid drainage.

A dual plug fuel shutoff valve uses a single shaft to simultaneously open or close supply and return lines.

A rotary valve uses a radial groove on the rotor surface to create fluid channels between inflow and outflow ports.

Segmenting hydraulic and mechanical zones reduces contamination and wear, extending actuator lifespan in ball valve applications.

Axial translation separates rotor from stator before rotation, reducing friction forces and enhancing sealing reliability in reciprocating compressors.

A shower tap water regulator channels residual fluid through a dedicated discharge opening to prevent dripping.

A hybrid faucet assembly joins a polymer upper support to a metallic lower base.

An integrated blocking mechanism uses a spring to restore position after leak detection, eliminating auxiliary components and easing repair.

A cam surface on the valve shaft drives locking balls into a mating groove to secure hydraulic connections.

A non-demountable vortex brake integrates a flushing access and hose connection for internal cleaning.

Segmented boot covers expose windows to drain fluid and remove debris, cutting rig time by simplifying access.

A seal assembly uses an elastic intermediate piece to space and bond separate sealing elements for reliable fluid control.

Feedback-regulated pressure pulses remove blockages while preventing conduit damage from uncontrolled force.

Spring-loaded sealing elements prevent fluid return hazards by balancing unbalanced drilling pressures.

An integrated travel stop assembly with a reversible bushing resolves the contradiction between valve positioning precision and actuator structural complexity.

Tensioned side segments encircle the plug member to prevent fluid particulate migration between seal interfaces, reducing friction and accumulation.
