Tilting Steam Traps

The operation of a tilting trap (see Figure 10-36) is intermittent in nature. With this type of trap, condensation enters a bowl and rises until its weight overbalances that of a counterweight, and the bowl sinks to the bottom. As the bowl sinks, a valve is opened, thus admitting live steam pressure on the surface of the water, and the trap then discharges. After the water is discharged, the counterweight sinks and raises the bowl, which in turn closes the valve, and the cycle begins again.
