Inverted Bucket Steam Trap | High Pressure Mechanical Steam Trap Manufacturer
Product Overview
The Inverted Bucket Steam Trap is a highly reliable mechanical steam trap designed for efficient condensate removal from steam systems while preventing valuable live steam loss. Utilizing the buoyancy principle of an inverted bucket, this steam trap automatically discharges condensate and non-condensable gases while maintaining excellent steam sealing performance.
Its rugged construction, resistance to water hammer, and long service life make it an ideal choice for demanding industrial applications such as power plants, refineries, petrochemical facilities, pulp and paper mills, and steam distribution systems.
Key Features
Excellent Steam Saving Performance
The inverted bucket mechanism automatically closes when steam enters the trap, effectively preventing live steam leakage and maximizing energy efficiency.
Durable Mechanical Design
Featuring a simple yet robust operating mechanism with few moving parts, the trap delivers dependable performance and extended service life.
Resistant to Water Hammer
Designed to withstand severe water hammer conditions and sudden pressure fluctuations commonly found in industrial steam systems.
Suitable for High Pressure Applications
Capable of operating efficiently in high-pressure and high-temperature steam environments.
Handles Dirt and Scale Effectively
Large internal passages reduce the risk of blockage caused by rust, dirt, and scale particles.
Low Maintenance Requirements
The simple mechanical construction minimizes maintenance costs and downtime.
Long Service Life
Hardened stainless steel internal components provide excellent wear resistance and long-term reliability.
Working Principle
When condensate enters the trap, the inverted bucket loses buoyancy and sinks, opening the valve and allowing condensate to discharge.
As steam enters the bucket, buoyancy increases, causing the bucket to rise and close the valve. This prevents live steam from escaping while maintaining efficient condensate removal.
The continuous cycle of rising and sinking enables automatic operation without external power.
