定义
A precision-engineered pneumatic fitting designed to establish a secure, leak-free connection between compressed air supply lines and air knife/blower nozzle assemblies. This component ensures optimal airflow delivery while maintaining system pressure integrity through standardized thread interfaces and sealing mechanisms.
工作原理
Operates by providing a mechanical interface that connects compressed air supply lines to air knife/blower nozzle bodies using threaded connections with sealing elements (typically O-rings or gaskets) to prevent air leakage. The connection maintains laminar airflow transition from supply line to nozzle body while withstanding operational pressure fluctuations.
材料
Typically manufactured from aluminum alloys (6061-T67075)brass (C36000)or stainless steel (304316) with Buna-N or Viton O-rings for sealing. Surface treatments include anodizing (aluminum)chrome plating (brass)or passivation (stainless steel) for corrosion resistance.
Seal Type
O-ring face seal or tapered thread seal
Thread Sizes
1/4", 3/8", 1/2", 3/4" NPT common
Flow Capacity
10-100 SCFM (depending on size)
Connection Type
NPT, BSPP, or BSPT threads
Pressure Rating
150-200 PSI (10-14 bar)
Temperature Range
-20°C to 120°C
标准
ISO 1179DIN 3852ISO 6149SAE J514

常见问题

What is the difference between NPT and BSPP thread types for air inlet connections?

NPT (National Pipe Taper) threads are tapered and seal through thread interference, while BSPP (British Standard Pipe Parallel) threads are parallel and require a separate sealing washer or O-ring. NPT is common in North America, BSPP in Europe and Asia.

How do I prevent air leaks at the inlet connection?

Ensure proper thread engagement (hand-tight plus 1.5-2 turns with wrench), use appropriate thread sealant (PTFE tape or liquid thread sealant for NPT), and replace worn O-rings regularly. For BSPP connections, ensure the sealing washer is undamaged and properly seated.

What maintenance is required for air inlet connections?

Regular inspection for leaks, checking thread condition, replacing O-rings annually or as needed, and cleaning threads before reassembly. Use thread gauges to verify thread integrity if disassembly is frequent.
