定义
A specialized industrial component designed for the controlled introduction of gases into sealed gas chambers. It consists of a threaded or flanged connection interface, internal valve mechanism, pressure-rated housing, and sealing system to maintain chamber integrity during and after gas filling operations.
工作原理
Operates through a spring-loaded valve mechanism that opens when external gas supply pressure exceeds chamber pressure, allowing controlled gas flow. The valve automatically seals when supply pressure is removed or equalized, preventing backflow and maintaining chamber pressure.
材料
Stainless steel 316L bodyPTFE sealsbrass or stainless steel valve componentsoptional nickel plating for corrosion resistance.
Flow Rate
15-20 SCFM at 100 psi
Leak Rate
<1x10^-9 mbar·L/s helium
Body Material
Stainless Steel 316L
Seal Material
Viton or PTFE
Connection Type
1/4" NPT female thread
Maximum Pressure
150 psi (10.3 bar)
Operating Temperature
-20°C to 120°C
标准
ISO 1179DIN 3852ASME B1.20.1

常见问题

What maintenance does a gas fill port require?

Regular inspection of seals for wear, cleaning of connection threads, and pressure testing every 6-12 months depending on usage frequency.

Can gas fill ports handle different gas types?

Yes, but material compatibility must be verified. Stainless steel 316L is suitable for most industrial gases including inert gases, while specialized seals may be needed for corrosive gases.

How do I ensure leak-free operation?

Use proper thread sealant or gaskets, torque connections to manufacturer specifications, and perform regular leak testing with appropriate detection methods.
