Diaphragm Valves TRIZ Cases
- Collapsible Casing Device for Emergency Wellbore Flow Control
Explosive pressure pulse deforms an internal insert to restrict fluid flow in a wellbore casing.
- Resin Fluid Control Valve Reinforcement for Sealing Integrity
A resin fluid control valve incorporates a bow-shaped metal reinforcement part within the valve seat support structure to enhance rigidity.
- Valve-to-Fitting Converter for Piping Section Isolation
A valve-to-fitting converter mounts on existing valves to isolate piping sections via integrated ports and a flow-blocking dam.
- Diaphragm Valve Expansion Member Sealing
Separate expansion member biases diaphragm into seated position, eliminating complex seat structures and maintaining seal under pressure surges.
- Hand Operation Unit for Suction Device with Segmented Pinch Valves
Segmenting the pinch valve into two independent mechanisms reduces manual force and enables continuous suction without permanent operator intervention.
- Feedstuff Valve Leak Sensor Integration
A feedstuff valve integrates a flowmeter with a Wheatstone bridge to detect membrane leaks via airflow changes.
- Flow Controller Expansion Chamber for Pressure Oscillation
An expansion chamber with an offset second flow passage diffuses fluid to reduce pressure oscillations in compact flow controllers.
- Pressure Modulating Dispensing Valve for Constant Flow Control
A dispensing valve with flexible diaphragms and throttle pins modulates flow paths to maintain constant liquid pressure.
- Hydraulic Valve Mechanism for Debris-Resistant Force Multiplication
A hydraulic valve assembly uses piston area ratios to multiply actuator force and engage the valve seat.
- Membrane Valve Sealing Bead Hardening Prevention
L-shaped recess and radial projection accommodate the sealing bead to distribute clamping forces across the diaphragm valve assembly.
- Multilayer Diaphragm Elastic Adhesive Layer Pressure Resistance
An elastic adhesive layer joins metal plates in a multilayer diaphragm, balancing high pressure resistance with smooth deformation for precise fluid control.
- Hemostatic Valve Assembly Radial Flexure Sealing
Radial flexure of the valve collar constricts the flexible member, preventing fluid leakage across varying device diameters.
- Reentrant Flow Path Valve Manifold for Deadleg Elimination
A reentrant flow path valve manifold directs gas through a cylinder to maintain continuous precursor movement.
- Modular Valve System Shared Membrane Fluid Separation
A modular valve system uses a shared membrane to separate control and process fluids, reducing mounting complexity and maintenance time.
- Hose Clamp with Two-Stage Locking and Side Placement
A hose clamp featuring a two-stage locking mechanism and spring-supported release for lateral placement on flexible conduits.
- Pressure Limiting Valve for Backflow Preventer Testing
A pressure limiting valve protects low pressure gauges from over-pressurization during backflow preventer testing.
- High Pressure Diaphragm Valve Exchangeable Seat Assembly
Extracted metal sleeve mounted in valve body prevents synthetic seat damage during high pressure oxygen adiabatic shock tests.
- Diaphragm Valve Flexible Heater Temperature Control
A flexible heater on the non-wetted diaphragm surface maintains thermal uniformity across wetted areas.
