Application and Characteristics of Machined Hex Nuts in Beer Machine Components

Core Application Scenarios

1. Tap / Dispense Tower Assembly
   Used to fix the tap to the tower and adjust the outlet direction, with gaskets for sealing, serving as a key connection point at the dispensing terminal.
2. Pipeline and Valve System
   Fasten sanitary pipe flanges, valve bodies, and fittings, withstand beer pressure and vibration from frequent switching, ensuring a leak‑free conveying line.
3. Tank and Frame
   Secure nozzles, legs, and internal components of fermentation and bright beer tanks, supporting the overall equipment structure and resisting workshop environment and cleaning corrosion.
4. Coupler and Gas Circuit
   Lock core parts such as CO₂ inlet nozzles and beer check valves, preventing gas leakage and beer backflow, ensuring stable gas supply and dispensing.

Key Technical Characteristics

Processing and Application Points

1. Processing Control
   Precision thread turning, control of pitch and width‑across‑flats tolerance; deburring to avoid scratching sealing surfaces; heat treatment for strength and toughness, preventing hydrogen embrittlement.
2. Installation Specification
   Clean threads and sealing surfaces, tighten step‑by‑step diagonally for uniform loading; fasten to specified torque to avoid thread damage from over‑tightening or leakage from under‑tightening.
3. Maintenance & Corrosion Protection
   Regularly check for looseness and corrosion, replace timely; avoid hard scratching during cleaning; passivation available for high‑humidity / corrosive environments to extend service life.
