定义
A precision-engineered threaded cap component used in pressure relief devices to provide controlled access for adjusting the set pressure, performing maintenance, and sealing the adjustment mechanism from environmental contaminants. It typically features a tamper-evident design and incorporates sealing elements to maintain system integrity.
工作原理
The adjustment cap functions as a protective and operational interface for the pressure adjustment mechanism. When rotated, it engages with internal threads to either compress or release the spring tension in the relief valve, thereby changing the set pressure at which the device activates. Its sealing surfaces prevent fluid leakage and contamination ingress while maintaining the calibrated pressure setting.

常见问题

How often should adjustment caps be inspected?

Adjustment caps should be visually inspected during routine maintenance cycles (typically every 6-12 months) and replaced if signs of corrosion, thread damage, or seal degradation are observed.

Can adjustment caps be reused after removal?

Yes, if undamaged and seals are replaced. However, torque values must be verified upon reinstallation to ensure proper sealing and pressure setting retention.

What causes adjustment cap leakage?

Common causes include damaged O-rings, cross-threading during installation, insufficient torque, corrosion on sealing surfaces, or thermal cycling effects on seal materials.
