Membrane tanks are simple devices for creating cumulative containers in closed type systems. Several types of such tanks are known, there are more often two: expansion and hydraulic accumulating. Expansion are used in heating systems, and hydro -accumulating systems in water supply and water treatment systems. The former often find use in individual residential buildings with their own heating system, the latter are used both in everyday life and in industrial hydraulic regulations. Membrane tanks have a container with a steel case and a rubberized membrane inside a container that divides the tank into two cavities. One of them serves to maintain compressed air, the other for filling with water during thermal expansion. The air chamber has a valve through which an excess of compressed air is pulled.
