Inverted bucket steam traps are mechanical steam traps that automatically block steam and drain condensate through the lifting and falling of an internal inverted bucket with the condensate level. Featuring reliable operation, strong resistance to water hammer, effective removal of non-condensable gases, large and stable discharge capacity, excellent sealing performance, good adaptability to load fluctuations and long service life,they are suitable for main steam pipelines, heat exchangers, large heating equipment, paper and textile machinery and other heavy-duty harsh working conditions, and are widely used in petrochemical, power, metallurgical, textile and other industrial thermal systems with high reliability requirements.
