定义
Orifice restrictors are precision-engineered fluid control components designed to regulate airflow by creating a calibrated restriction in pneumatic distribution channels. These devices maintain consistent pressure differentials, control flow rates, and ensure stable operation of downstream pneumatic equipment through precisely machined orifices with controlled cross-sectional areas.
工作原理
Operates on the principle of flow restriction through a precisely sized orifice, creating a pressure drop proportional to flow rate according to Bernoulli's principle and orifice flow equations. The restriction converts pressure energy to kinetic energy, controlling mass flow rate while maintaining system stability.
材料
Stainless steel (AISI 304/316)brass (C36000)aluminum (6061-T6)engineered plastics (PEEKPTFE)with surface finishes Ra ≤ 0.8 μm for precision applications.
Leakage Class
ANSI/FCI 70-2 Class IV or better
Connection Type
NPT, BSPP, SAE, flange
Pressure Rating
0-150 psi (0-10 bar)
Orifice Diameter
0.1-10.0 mm
Temperature Range
-40°C to 200°C
Flow Coefficient (Cv)
0.001-2.5
标准
ISO 6358ISO 1219DIN 24342ANSI/B93.5

常见问题

What is the primary function of an orifice restrictor in air distribution systems?

The primary function is to precisely control airflow rate by creating a calibrated restriction, maintaining consistent pressure differentials, and ensuring stable operation of downstream pneumatic equipment.

How do I select the correct orifice size for my application?

Selection requires calculating required flow rate, system pressure, acceptable pressure drop, and fluid properties using orifice flow equations, typically with a safety factor of 1.2-1.5 for varying conditions.

What maintenance is required for orifice restrictors?

Regular inspection for contamination buildup, verification of flow characteristics, and replacement when erosion changes orifice dimensions beyond tolerance (typically ±2% of specified diameter).
