技术定义与适配语境
典型 填充/分配端口 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A precision-engineered component integrated into cryogenic storage vessels that enables safe, controlled transfer of liquefied gases (such as liquid nitrogen, oxygen, or argon) into and out of the vessel while maintaining cryogenic temperatures and preventing contamination or pressure loss.

组件规格

定义
A precision-engineered component integrated into cryogenic storage vessels that enables safe, controlled transfer of liquefied gases (such as liquid nitrogen, oxygen, or argon) into and out of the vessel while maintaining cryogenic temperatures and preventing contamination or pressure loss.
工作原理
Utilizes vacuum-insulated or multi-layer insulated construction with specialized valves and seals to minimize heat transfer during fluid transfer operations. The port maintains a closed system during operation to prevent atmospheric contamination and moisture ingress while allowing precise flow control through integrated valves and pressure regulation mechanisms.
材料
Stainless steel 316L (primary)with cryogenic-grade elastomers (PTFEKalrez) for sealsand vacuum-jacketed construction with multilayer insulation (MLI) for thermal protection
Flow Rate
10-100 L/min (liquid)
Heat Leak
<1.5 W/m
Port Size
1/2" to 2" NPT or ISO
Vacuum Level
<10^-3 mbar
Connection Type
Bayonet, Tri-Clamp, or Flanged
Maximum Pressure
10-25 bar
Operating Temperature
-196°C to 50°C
标准
ISO 21013DIN 28400ASME B31.3

常见问题

What maintenance is required for cryogenic fill/dispense ports?

Regular inspection of seals and valves, vacuum integrity checks every 6-12 months, and cleaning with appropriate cryogenic-compatible solvents to prevent ice buildup and contamination.

Can these ports be used with different cryogenic fluids?

Yes, but material compatibility must be verified. Ports designed for liquid nitrogen may require different seals or materials for oxygen service due to oxidation risks.
