Method of production of an accumulator unit for a concentrates preparation device

摘要

The invention relates to a design method for the accumulator. The method comprises providing a sealing barrel, a first duct, a second duct, a third duct,a fourth duct, a first water valve, a second water valve, a third water valve, a fourth water valve and a water level tagging pipe; communicating the barrel with the outside through the first, second, third, and fourth ducts; arranging for the first, second, third, and fourth ducts to switch between opening and closing respectively through the first, second, third and fourth water valves; connecting the third water valve of the accumulator with the input end of the depressurization unit through the duct; communicating the first and fourth water valves with the atmosphere. Arranging for the second and third water valves to be fixedly connected with each other by the connecting block so as to rotate together, such arrangement increases the stability of the device, and avoids dilution by condensed water.
