Expansion tank, pressure tank, surge tank, pressure tank, bladder pressure tank air conditioning system with expansion tank is made of steel casing, the energy storage device consisting of a rubber balloon bladder, rubber bladder to completely separate water chamber and the gas chamber, when When the external pressure of water filled balloon-type pressure tank liner, the seal is compressed air in the tank, according to Boyle's gas law, the gas being compressed smaller size, pressure increases to store energy, compressed gas expansion It can pressure rubber balloon inside the tank.
Expansion tank with a balloon is a gas (usually nitrogen) water system into two parts sealed container; it is used in heating and air-conditioning water in a closed system expands the amount of water absorbed heat, water and pressure balancing system; the system cooling , nitrogen precharge pressure of the balloon to push in the end portions, the system enters the expansion tank is not water, the water temperature when the system pressure increases, the pressure is higher than the precharge nitrogen pressure, thermal expansion of the water into the expansion tank.
Expansion tank widely used in central air conditioning, boiler, fire, water treatment, water heaters and other areas; central air conditioning circulating water regulator, distilled water supply expansion systems, water heating system circulating water regulator, fire water system water regulator, frequency conversion water supply Regulators, boiler feed water, air pressure water supply and other occasions.
Features: Expansion tank in closed water circulation system play a role in the balance of water and pressure relief valve to avoid frequent opening and automatic water valve replenishment frequently, etc. In addition, in the water system, the expansion tank can also reduce frequent starting of the pump can be used absorption system due to water hammer valves, pumps, etc. caused by the opening and closing, as well as a small amount of water at night so that the water supply system to reduce the power consumption of the main pump hibernation, extend pump service life.
Airbag structure inside the tank to ensure the water is not in contact with the tank wall, so no rust inside the tank wall, external non-condensing phenomenon, greatly extended service life compared with conventional expansion tank in refrigeration and HVAC systems, with easy installation ( Do not install at the highest point) small footprint, no secondary pollution, long life and many other advantages. specification: 2L; 4L; 5L; 8L; 12L; 18L; 19L; 20L; 24L; 25L; 36L; 50 L; 60 L; 80 L; 100 L; 150 L; 200 L; 250 L; 300 L; 500 L; 750 L; 1000 L;; 1500 L; 2000 L; 3000 L
