Component Specifications

Definition
A threaded mechanical component designed to precisely regulate the pressure of starch slurry within pressure control valves by adjusting the position of internal valve elements through rotational movement, typically featuring fine threads and calibrated markings for accurate pressure settings.
Working Principle
Operates through rotational motion that translates into linear displacement, compressing or releasing internal valve springs or diaphragms to modify the flow restriction and thereby control the pressure of starch slurry passing through the valve assembly.
Materials
Stainless steel 316L (AISI 316L) with corrosion-resistant coating, hardness: HRC 35-40, surface finish: Ra 0.8 μm
Technical Parameters
  • Length 40 mm
  • Head Type Hex socket (Allen) 6 mm
  • Thread Type M12 x 1.5 mm fine pitch
  • Torque Range 5-15 Nm
  • Temperature Range -10°C to 120°C
  • Corrosion Resistance IP67 equivalent
  • Pressure Adjustment Range 0.2-2.0 MPa
Standards
ISO 4762, DIN 912, ISO 898-1

Engineering Analysis

Risks & Mitigation
  • Thread galling due to starch residue accumulation
  • Over-torquing leading to thread stripping
  • Corrosion in high-moisture environments
  • Misalignment causing uneven pressure distribution
FMEA Triads
Trigger: Starch residue buildup in threads
Failure: Seized screw preventing adjustment
Mitigation: Implement regular cleaning schedule with food-safe solvents and apply food-grade lubricant
Trigger: Excessive torque during adjustment
Failure: Stripped threads or damaged valve seat
Mitigation: Use calibrated torque wrenches and provide operator training on proper adjustment procedures
Trigger: Material fatigue from cyclic loading
Failure: Screw fracture under pressure
Mitigation: Implement preventive replacement schedule based on cycle count and conduct regular visual inspections

Frequently Asked Questions

What maintenance is required for pressure adjustment screws in starch slurry applications?

Regular inspection for thread wear, cleaning to prevent starch buildup, and lubrication with food-grade anti-seize compound every 6 months or 2,000 operating hours.

How do I calibrate the pressure adjustment screw?

Use a calibrated torque wrench to apply specified torque values while monitoring pressure gauge readings, following manufacturer's calibration procedures with reference to pressure-volume curves.

Can this screw be used with other slurry types?

While designed for starch slurry, it can handle similar viscosity non-abrasive food slurries, but not recommended for abrasive or chemically aggressive media without material verification.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
