Toilet water inlet valve principle

The toilet inlet valve uses a float to control the opening and closing of the water valve. When you release water for flushing, the water level in the water tank drops, and the float also drops, and drives the water inlet piston up through the connecting rod, and the water valve opens, realizing automatic water replenishment in the water tank. When the water level rises, the floating ball rises and drives the water valve piston down. When the water level reaches a certain level, the piston completely blocks the water inlet and the water valve stops water inflow.
