Solution for Powder Butterfly Valve

• Analysis of Common Problems
  

  Sealing surface wear and leakage:

  Long-term conveying of powder with impurities is likely to cause wear on the sealing surface, leading to powder leakage, which pollutes the environment, wastes raw materials, and affects the discharge accuracy of the silo.
  

  Butterfly plate jamming and difficult opening/closing:

  Powder accumulation in the valve cavity or entering the valve shaft gap can easily cause the butterfly plate to jam, making it impossible to open and close normally, interrupting powder conveying and slowing down the production rhythm.
• Overall Solutions
  

  Regular inspection and seal replacement:

  Check the wear of the sealing surface monthly and clean impurities; when seal failure is found, replace the special wear-resistant seals in time to restore sealing performance and prevent leakage.
  

  Valve cavity cleaning and lubrication maintenance:

  Dismantle the valve cavity every two weeks to remove accumulated powder, and apply high-temperature wear-resistant lubricant to the valve shaft to reduce friction, avoid butterfly plate jamming, and ensure smooth opening and closing.
