When water flowing down the power pipe reaches the vicinity of the bleed valve, the momentum of the water flow (sufficient momentum if the flow velocity is high enough) causes the valve to close quickly. The water flow stops suddenly, the kinetic energy of the water flow is converted into pressure energy, then the pressure of the water in the pipe rises, the drain valve is flushed, and part of the water enters the air chamber and rises to a certain height along the water outlet pipe. Then, because the pressure in the power pipe is reduced, the drain valve automatically falls under the action of dead weight and returns to the opening state. At the same time, the compressed air in the air chamber forces the trap to close, and the entire process is repeated.
