Plug Valves TRIZ Cases

Double-seat valve prevents direct pressurization of the seat area via pre-lift phases and tangential flow paths.

Segmented RF-controlled valve shuts off polybutylene piping flow to prevent oxidation leaks while maintaining sprinkler pressure.

An axial locking slide plate secures insulated valves without disturbing thermal layers.

A dual seat ball valve design equalizes pressure between sealing surfaces to reduce contact forces and prevent deformation.

An elliptical valve seat with a hemispherically contoured sealing face creates a fluid-tight seal around the spherical ball member.

A conically widening outlet bore ensures complete drainage of liquid samples through unstable adhesion and gravity.

A trunnion ball valve packing uses a pressing mechanism to increase seal surface pressure at the tip outer peripheral region.

Local radius variations on the plug and house create a tight seal, eliminating costly silicone coatings and reducing operational effort for fluid drainage.

Segmenting the valve into a fixed housing and removable cartridge allows rapid maintenance while keeping the pipeline connected.

Segmented bridging elements alter internal fluid resistance to establish linearity between rotation angle and flow rate, eliminating non-linear control errors.

Porous lattice cores in additive manufactured ball valves cut weight by half without sacrificing strength, easing transport and assembly.

A mix-proof double seat valve uses a hollow rod design to create a self-draining leakage cavity for leak-free switching.

An integrated check valve within a disposable dental valve prevents backflow and cross-contamination, eliminating the need for separate sterilization cycles.

Segmenting stop contours onto a separate control housing eliminates tight tolerance coordination between housings, simplifying manufacturing.

Closed liquid medium actuation reduces sanitary valve size while preventing contamination risks.

Disposable rupture valves eliminate cleaning cycles by selectively rupturing under downstream pressure to maintain sterility.

Radial arms and stoppers balance actuation forces on a conical rotary valve rotor, preventing torsion and leaks in chromatographic systems.

Resilient cup springs bias sealing rings against housing seats, reducing friction and wear while maintaining high sealing reliability.

Segmented housing parts and extractable rotors resolve cleaning accessibility trade-offs, enabling complete residue-free disinfection without system shutdown.

Superhard material tips on choke plugs resist wear and erosion from high pressures, extending system operation time without replacing components.

Angled locking apertures secure a valve shaft using internal pressure to enhance engagement between locking members and the closure member.

A rotatable spherical closure piece aligns a through-channel to release waste water flow from a floor cleaning machine hose.

A tapered rotary feed valve shapes its bore to accommodate thermal expansion differences between the rotor and housing.

A compartmented beverage bottle uses an inter-compartmental valve to control fluid flow between sealed primary and secondary chambers.

Variable-radius guide slot and eccentric cam control short throw valve closure to prevent water hammer damage in piping systems.

A three-way valve structure uses a cylindrical rotating obturator to control fluid flow through perpendicular outlet channels.

Segmented plug valve components absorb thermal expansion and axial forces, preventing misalignment and component wash-out.

A water inlet valve filter dividing mechanism separates flow paths to protect internal components from debris accumulation.

A diaphragm-based mixing chamber balances hot and cold water flows, reducing leakage risks in single supply faucets.

A ball valve assembly uses a recessed cam feature to engage a spring-loaded seal member during rotation.

A water jet pump appliance mixes shower water with fragrance media from replaceable capsules, enabling dynamic customization without complex control systems.

A rotating nozzle inside a mix-proof valve creates a cleaning spray driven by pressurized media.

A rotating valve assembly uses a cooling system to create a thermal barrier between the inner cup and bearing arrangement.

A double seat valve uses a flow contour to guide cleaning agent smoothly along the seat area.

Support lands stabilize seal bodies in a single fluid opening, reducing packaging space and manufacturing complexity.

Segmented wedge geometry maintains sealing force across positions, reducing maintenance downtime without removing the valve body.

Inclined valve pivots orient control knobs upward, eliminating the need to bend down for water flow adjustment.
