2014 - diaphragm pressure tank - wholesale prices - the national shipping

The device is implanted in a pressure tank and pressure tank shape same rubber diaphragm between the diaphragm and the pressure tube into the pressurized gas to ensure gas and water balance. Water and gas completely isolated; water and non-contact surface pressure tank. Under basic conditions, non-toxic fully inflated membrane can enhance the expansion tank of their own performance and extend the life of the product. Design temperature: -10 ℃ to + 110 ℃ standard 97/23 / CE (PED) (5 to 25L) maximum working pressure of this equipment were 0.6mpa / 1.0 mpa / 1.6 mpa, fire water storage volume greater than 150L / 300L / 450L, regulated water volume greater than 50L, when used in hydrant systems, water gun flow per share of 2.5L / S, 5L / S, enrich the water column length 7M, 10 M, 13M; when used in sprinkler systems, each nozzle flow rate of 1.0L / S, nozzle pressure 0.1mpa. The device allows the most negative point of fire water piping system is always fire pressure, and the use of pressure tank within 30 seconds there is always fire water reservoir; the operating pressure of the device utilizing the pressure tank set, control pump operating conditions, reach booster regulator function. Diaphragm pressure tank is made of steel casing, the energy storage device consisting of a rubber membrane liner, rubber diaphragm water chamber is completely separated from the gas chamber, when the external pressure of the water filled diaphragm pressure tank liner, seal compressed air in the tank, according to Boyle's gas law, the gas being compressed smaller size, pressure increased stored energy, compressed gas expansion may be hydraulic rubber diaphragm inside the tank. Changes rubber diaphragm tank schematic work: Adaptation: diaphragm pressure tank is widely used in 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 regulator , boiler feed water, air pressure water supply and other occasions. Features: ?? tank inner membrane structure ensures that 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. ?? Rubber diaphragm can be more than 20 million times diastolic, inflated long-term use.
