Define the expansion tank: expansion tank, also known as pressure tank, pressure tank or pressure expansion tank is an automatic regulator of functional products, widely used in various closed-cycle systems and water supply, water supply and fire-fighting equipment, the main the tank, flange, balloons, inflating and deflating needle valve and end caps of five parts, there are two kinds of materials of stainless steel and carbon steel. The role of the expansion tank: The expansion tank is widely used in air conditioners, solar, boilers and other HVAC systems and water and fire-fighting equipment, the buffer system pressure fluctuations. The overall effect of the expansion tank pressure fluctuation buffering system, not the system pressure increases the system pressure drops too fast nor too Meng, let the system at a relatively steady pressure to run, but in the closed-loop system and the role of the water supply system which is not exactly the same, in the air conditioning, solar, boiler, floor heating and other closed-cycle systems, the role of the expansion tank is to absorb the volume expansion of the working medium temperature volume expansion tank, to prevent the system pressure rises too fast, lower the temperature in the working medium volume shrinkage of liquid within the balloon release, the supplement to the system, not the system pressure drop over Meng, reducing replenishment times the number of pressure relief valve and automatic water valve; in the frequency of water supply, water supply and pressure the fire protection water supply system, a major role in the expansion tank is the buffer pump start and stop, and system valves open and close the water hammer produced when, to prevent water hammer damage components on the piping and systems, as well as low water peak guarantee Pump adequate sleep time, not only saving but also to extend the service life of the pump. Expansion tank types: expansion tank according to the structure can be divided into bladder-type expansion tank and diaphragm expansion tank, the difference lies in the bladder-type expansion tank when the water does not work in contact with the tank wall, long life, and diaphragm expansion tank work tank Usually the body wall almost directly with the water contact, easy to rust failure and cause secondary pollution of water, due to the above disadvantages, diaphragm expansion tank is currently phasing out of the market; the expansion tank can be classified according to the material of carbon steel and stainless steel expansion expansion tank cans, steel expansion tank bladder-type structure can meet the requirements of the vast majority of the system, but in the field of food and other special stainless steel expansion tank must be used; expansion tank by the pressure resistance is usually divided into 6bar, 8bar, 10bar, 16bar and 25bar five kinds of pressure, the higher the pressure of the occasion, such as a hydraulic accumulator system to use more of, 6bar 8bar expansion tank and meet most of the requirements of the HVAC system, 10bar, 16bar and 25bar expansion tank used for water supply and fire protection systems , pressure resistance depends on the expansion tank and the tank wall thickness of the balloon wall thickness, under the same conditions, the thickness, the higher pressure; expansion tank can be divided by the heat resistance temperature of 70 degrees, the temperature of 100 degrees and three temperature 130 degrees, the heat resistance of different materials varies airbag, general water supply equipment medium temperature is normal, the temperature 70 degrees in the expansion tank is sufficient to use air conditioning, boiler and heating system in general temperature of 100 degrees Nine expansion tank to meet the requirements, but in the solar system, in particular pressure solar system under the summer sun nausea, medium temperatures over 100 degrees, this time we should use 130-degree temperature the expansion tank; expansion tank structure : expansion tank structure can be divided into two kinds of bladder-type and diaphragm, diaphragm expansion tank diaphragm is fixed by hot rolling in the tank center, as shown below: This process if not handled well, will leave tiny pores between the inner and steel, these tiny pores will pre-charge the gas leaked out, the expansion tank if gas leak, 90 percent is from here leaked this leak of a period of time if the expansion tank no additional gas can not play constant pressure unloading, which in itself is difficult to detect. Further expansion tank diaphragm tank wall almost half since the direct contact with the water, though its interior is also done anti-rust treatment, but a long soak in the water tank as will be the case of rust, which is why the diaphragm expansion After a period of time the tank pour out the water was yellow. Since the tank wall thickness is generally about 1mm, interfaces directly welded to the tank, which can withstand torsion coupling manner quite small. And when you install the tank can only hold the housing rotation, so if the force is too large or too Meng, will spin off the interface. Bladder-type expansion tank has been considerable progress in the structure, to overcome the above disadvantages, as: bladder-type expansion tank inside a whole balloon, water enters only at work inside the balloon, no contact with the housing, interface usage Flanges connection, avoiding the rust problem caused by the welding process, the tank wall is not in contact with the water, avoid the possibility of rust and secondary pollution of water quality, long life, and the expansion tank of this structure, even if the airbag damage also available separately Replace avoided after diaphragm rupture diaphragm expansion tank to scrap the entire jar problem, the same, as is the flange connection, so its interface can withstand a lot of torque, the installation process is not afraid of the interface will be broken.
