定义
A precision-engineered component in rotary gas injectors that controls the flow, direction, and atomization of gases during injection processes. It features calibrated orifices, specialized tip geometries, and material compatibility for specific industrial applications requiring accurate gas delivery.
工作原理
Operates by receiving pressurized gas from the injector body and directing it through precisely machined orifices. The nozzle geometry controls flow characteristics, while rotary motion ensures even distribution. Pressure differentials between the injector and process environment enable controlled gas release.
材料
Stainless steel (316L/304)tungsten carbideceramic (alumina/zirconia)or specialized alloys (HastelloyInconel) depending on chemical compatibility and wear resistance requirements
Flow Rate
0.5-50 L/min
Surface Finish
Ra ≤ 0.8 μm
Connection Type
Threaded (NPT, BSP), flange, or quick-connect
Orifice Diameter
0.1-5.0 mm
Temperature Range
-50°C to 500°C
Operating Pressure
0.1-10 MPa
标准
ISO 5167DIN 1952ASME B16.5

常见问题

What factors determine injection head material selection?

Material selection depends on chemical compatibility with injected gases, operating temperature/pressure, wear resistance requirements, and industry-specific regulations (e.g., food-grade stainless steel for food manufacturing).

How does nozzle geometry affect injection performance?

Nozzle geometry controls flow patterns, atomization quality, spray angle, and distribution uniformity. Different tip designs (flat fan, hollow cone, full cone) serve specific application needs.

What maintenance is required for injection heads?

Regular inspection for clogging, wear measurement of orifice dimensions, cleaning with compatible solvents, and replacement based on flow rate deviation or visible damage.
