Bladder type water expansion tank is an energy storage device composed of steel shell and rubber diaphragm inner tank. The rubber diaphragm completely separates the water chamber from the air chamber. The air in the tank is compressed. According to Boyle's gas law, the gas is compressed to a small volume, and the pressure rises to store energy. The expansion of the compressed gas can press the water in the rubber diaphragm out of the tank.
