Solution for Powder Butterfly Valve

• Analysis of Common Problems
  

  Powder clogging in valve cavity:

  When powder has poor fluidity or high humidity, it tends to accumulate and clog in the valve cavity, resulting in unsmooth aperture adjustment, affecting powder conveying volume and even interrupting production.
  

  Diaphragm wear and powder leakage:

  Long-term conveying of hard powder easily wears the diaphragm, causing gaps and powder leakage, which pollutes the environment, wastes raw materials and reduces conveying efficiency.
• Overall Solutions
  

  Optimized valve cavity design and humidity control:

  Adopt an inverted conical valve cavity to reduce accumulation; pre-dry high-humidity powder. Purge the valve cavity with compressed air after daily shutdown to remove residual powder and prevent clogging.
  

  Adopting wear-resistant diaphragms and regular inspection:

  Use polyurethane wear-resistant diaphragms; inspect diaphragm wear monthly. Replace promptly if scratches or thinning occur to avoid powder leakage and ensure sealing performance.
