Principle of water stop water valve of flush toilet

1. When the water is released, pull the water knob and the knob will go through the lever.So the water in the tank will come out.When the water is released, the drain plug falls, blocking the outlet.At this point, the float also falls on the surface, at the bottom of the tank.The drop of the float pushes the lever into the water and the water into the tank.As the surface of the water rises, the floating ball will gradually rise due to buoyancy until the water pressure is pushed down through the lever to plug the inlet.The tank is filled with water.

2. When the inlet pipe is leaking due to failure (e.g. the water inlet plug cannot stop the water inlet or the water pipe burst), the water surface in the water tank will continue to rise and eventually overflow the tank.This problem is solved by the setting of water permeable pipe.When the water level rises to the opening of the water seepage, the water will flow from the seepage into the toilet and will not overflow the water tank.When the water pipe is working normally, the water in the water tank will not reach the water seepage, so there is no need to worry about the water flowing away.
