Experience Sharing: Refrigeration Solenoid Valve Working Principle and Inspection Points

Refrigeration solenoid valve is an electrically controlled on-off valve for liquid or gas refrigerant pipeline. The valve opens or closes refrigerant passage under the signal from cold room control system. It cuts off liquid refrigerant supply to air cooler when the zone reaches preset temperature. Coil heating and valve seat sealing status are the two key inspection items during maintenance. Liquid line solenoid valve should be installed horizontally and avoid direct impact from liquid hammer. Formal refrigeration factory selects solenoid valve specification according to refrigerant type and pipeline diameter. Xindacool installs high-quality refrigeration solenoid valves on liquid pipeline of each air cooler branch. Coil burnout or valve seat dirt clogging will lead to failure of refrigerant cut-off function. Around 30% of cold room temperature out-of-control faults relate to abnormal solenoid valve operation. Power supply of solenoid valve must match coil rated voltage to prevent coil burning. After long time shutdown, check valve action before restarting refrigeration system. Normal solenoid valve operation realizes independent refrigerant on-off control for each cooling branch.

FAQ

  1. Q: What function does refrigeration solenoid valve undertake? A: Electrically control opening and closing of refrigerant pipeline passage.
  2. Q: Where is liquid line solenoid valve commonly mounted? A: On liquid pipeline before each refrigeration air cooler.
  3. Q: What common faults happen on solenoid valve? A: Burned coil or dirt blocking valve seat causing seal failure.
  4. Q: What percentage of temperature out-of-control links to solenoid valve fault? A: 30% of cold room temperature runaway faults are caused by abnormal solenoid valves.
  5. Q: What installation requirement applies to liquid line solenoid valve? A: Install horizontally to reduce liquid hammer impact.
