Inlet Port with Cap: Temperature Range -20°C to 100°C

Component Specifications

Definition

The Inlet Port with Cap is a critical component of reagent storage tanks, providing a secure and sealed entry point for introducing chemical reagents. It consists of a threaded or flanged port integrated into the tank structure, paired with a removable cap that ensures hermetic sealing when closed. This component prevents contamination, evaporation, and exposure to environmental elements, maintaining reagent purity and safety. It typically includes gaskets or O-rings for enhanced sealing and may feature tamper-evident or locking mechanisms for security in industrial applications.

Working Principle

The inlet port allows controlled access to the tank interior for reagent filling, while the cap creates a pressure-tight seal using mechanical compression (via threads, clamps, or latches) against a gasket or sealing surface. This prevents air ingress, moisture contamination, and volatile emissions, ensuring stable storage conditions. Some designs incorporate venting features or pressure-relief mechanisms to handle tank pressurization during filling operations.

Materials

316L stainless steel (for corrosion resistance), PTFE (for chemical inertness), EPDM or Viton gaskets (for sealing), polypropylene (for cost-effective applications). Material selection depends on reagent compatibility, temperature range (-20°C to 100°C typical), and pressure requirements (up to 10 bar).
