定义
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.
工作原理
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.

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
标准
ISO 4762DIN 912ISO 898-1

常见问题

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.
