Filling/Draining Ports: Temperature Range -20°C to +120°C

Component Specifications

Definition

Engineered interface components designed for controlled electrolyte transfer in electrochemical systems, featuring precision sealing mechanisms and corrosion-resistant construction to maintain electrolyte purity and prevent contamination during filling and draining operations.

Working Principle

Utilizes threaded or quick-connect couplings with integrated sealing gaskets to create leak-proof connections. During filling, electrolyte flows through the port into the reservoir while maintaining system pressure balance. Draining operations employ gravity or pump-assisted flow through dedicated outlets with shutoff valves to prevent accidental discharge.

Materials

316L stainless steel, PTFE (polytetrafluoroethylene), FKM (fluoroelastomer) seals, PEEK (polyetheretherketone) for high-temperature applications

Frequently Asked Questions

What maintenance is required for electrolyte filling ports?

Regular inspection of seals (every 6 months), cleaning of connection surfaces, and verification of torque settings on threaded connections. Replace seals annually or as indicated by visual inspection.

Can standard fluid ports be used for electrolyte applications?

No. Electrolyte ports require specific corrosion-resistant materials (316L stainless, PTFE) and specialized seals (FKM) to withstand chemical attack and prevent contamination.

How are these ports tested for leak prevention?

Pressure testing at 1.5x operating pressure with helium leak detection (sensitivity 1×10⁻⁶ mbar·L/s) and visual inspection under UV light with fluorescent dye.
