Structure Characteristics and Working Principle

When the trap does not start working, freely semi-ball-float sinks in the emission tube, when the trap is in the drainage state, steam go into the body through the filter net and emission tube, as the steam volume increased to a certain degree, buoyancy causes semi-float ball upward, under the effect of steam pressure, the semi-float ball lean against trap spray nozzle to close it, preventing steam escaping. When a large quantity of condensation water go into the body, steam volume inside the semi-float ball reduces, the semi-float ball fall off under the effect of its own gravity, then the semi-float ball break away from the trap spray nozzle, completing a working cycle. So movements in cycles can achieve the purpose of automaticly steam drain prevention.
