A free half-float trap is one of the most reliable traps in mechanical traps. Its internal structure is only a semi-floating ball bucket for moving parts, opening down, semi-ball bucket cylindrical ball after grinding, the entire spherical surface can be sealed. Long life, water hammer, no wearing parts, trouble-free, durable, no steam leakage, energy-saving effect. The trap is widely used in steam heating equipment, steam pipe network condensate recovery system, is one of the most advanced structure of the trap today. Free half-float trap only a semi-float ball bucket for the moving parts, opening down, the bucket is the opening and closing pieces, but also the seal. When the device is just started, air and low temperature condensate in the pipeline enter the steam trap through the launch tube. The bimetallic emptying element in the valve bounces the bucket open, the valve opens, and the air and low temperature condensate drain rapidly. When the steam enters the bucket, the bucket produces upward buoyancy, while the temperature inside the valve rises, the bimetallic emptying element contracts and the ball is poled toward the valve port and the valve is closed. When the steam inside the bucket becomes condensed water, the bucket loses its buoyancy and sinks, the valve opens and the condensate drains quickly. When the steam enters the barrel again, the valve is closed again, intermittently and continuously. As the valve seat in the water seal isolation, water vapor separate, no steam leakage during work.
