Diaphragm Valves TRIZ Cases

A rotary pinch valve uses a cam mechanism and pneumatic assistance to close the sleeve.

Direct rivet attachment eliminates sleeve-induced stress, ensuring rapid closure and long-term reliability.

A deformable valve controls liquid flow in microchannels by altering capillary pressure through wall deformation.

A shape memory alloy flow control device uses printed resistive traces to heat and deform flaps for rapid fluid regulation.

A shut-off valve diaphragm deforms against endless projections to absorb impact energy and prevent particle generation during contact.

Positioning parts align projections to minimize sealing area and prevent fluid leakage without increasing release force.

Axial locking protrusions engage holder recesses to prevent unintended valve rotation from fluid pressure changes.

A one-way valve uses a membrane with a stiffened outer peripheral portion to restrict deflection over the seat.

A pilot-operated regulator with diaphragm protection maintains stable outlet pressure by controlling exhaust valve operation based on feedback sensors.

Convolute gussets bias the sealing body to prevent delamination and extend lifespan beyond one million cycles.

A pneumatic controller uses a diaphragm and detent mechanism to switch an output port between atmospheric pressure and vacuum.

An emergency switch breaks internal equal pressure in a diaphragm valve, enabling manual operation when solenoid failure prevents automatic control.

Segmenting the welded base from the removable membrane assembly resolves the trade-off between mounting reliability and ease of disassembly.

Hooks and engaging pieces replace thermal fusion, enabling easy assembly and repair while maintaining connection strength.

A constricting pressure valve apparatus uses a pressurizable membrane to open and close within a housing structure.

A manual valve uses a dual cutoff mechanism to seal the flow path through screw-driven force.

Segmentation isolates tube sections to reduce energy consumption during maintenance while maintaining reliable pressure control.

A metal diaphragm valve integrates a resin layer to buffer thermal expansion, stabilizing the Cv value within 10% after ten million high-temperature cycles.

Flexible membrane closing device manages shredded waste discharge to prevent pipe blockages and odor issues.

A magnetic field deforms a duct membrane to route washer fluid through a single pipe, eliminating complex multi-pipe installations.
