Constant pressure water expansion tank works and models of election Ze, the use of negative pressure water systems in use, constant pressure water tank material quality carbon steel, stainless steel two types, the quality of clearance, the full range of models, the expansion tank (constant pressure tank, pressure tank, pressure tank, surge tank) is a steel shell, interior storage device consisting of a rubber balloon, rubber balloon the water chamber is completely separated from the gas chamber. Expansion tank heating and air conditioning used in a closed system to absorb water expands when heated in water, and water balance system pressure; when the system is cooled, pre-filled with nitrogen pressure to push the balloon in the end, systems of water did not enter the expansion tank, when the system water When the temperature rises, the pressure increases, the pressure is higher than the pre-filled with nitrogen gas pressure, the thermal expansion of water into the expansion tank. Expansion tank Adaptation: expansion tank is widely used in central air conditioning, boilers, fire protection, water treatment, water heaters and other areas; expansion tank is also used in central air conditioning circulating water regulators, steam water supply expansion systems, water heating system circulating water stable pressure, fire water system water regulator, the regulator conversion water supply, boiler feed water, water supply and other pneumatic applications. Expansion tank features: expansion tank played a role in the balance of water and pressure in a closed water circulation system, the safety valve to avoid frequent opening and frequent replenishment, such as automatic water valve. In addition, the water system, the expansion tank can also reduce the frequent start the pump can be used to absorb the impact of the 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 in order to reduce the use of the main pump hibernation electricity and prolong the life of the pump and so on. Expansion tank features: expansion tank inside the balloon structure ensures the water is not in contact with the tank wall, so no rust inside the tank wall expansion, expansion tank outside without condensation phenomenon, greatly extended service life. Compared with the traditional expansion tank expansion tank in refrigeration and HVAC systems, expansion tank with easy installation (not installed at the highest point) small footprint, no secondary pollution, long life many advantages. Expansion tank specifications: 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. Our distribution model given the low pressure water tank full price, good quality and welcome to order.
