Magnetleeh controlled Yentil.

Di · acidification inspects eloh on nagnetlaoh controlled valves for flowing liquids or ^ö aee in which the the Hauptflufl sprrende Ventilkeg »l is pressed by the liquid pressure against the Yentilsit" and an opening of the valve is effected by Dafi means of an electromagnetic control • ine Bore in the valve cone is opened, through which the fluid pressure on both sides of the valve cone can be equalized.As a rule, such valves are designed as piston valves, with the inflowing fluid flowing through a narrow annular gap between the piston and the valve body behind the piston, see above That this is pressed by the liquid pressure against the valve seat as long as its bore is closed. So, instead of using a piston valve alone, membrane valves are already used, ie valves in which the valve cone is connected to the valve body by a membrane. With one or more bores, the pressure between the inlet pipe and the rear side of the membrane can be equalized, so that the valve cone is pressed onto the valve stem by this overpressure. However, these membrane valves have not proven themselves in the long term, since the membranes were never destroyed quickly.

The foolish innovation is based on the knowledge that this Destruction of the membranes due to excessive loading which is based on the fact that uhvewieidbar in the lines

Heuerungsgeaäe this overstressing of the estbrane is remedied by the fact that the skin of the eye lying on the lower pressure core of the membrane, including the inside of the housing cover 6, is held in the shape of a flat plate, so that the cover is held in the open position on the membrane and thus on this cover will. Sine eo supported membrane can withstand much higher overpressure than a freely stretched membrane. So that the Xruokaua equal between the two sides of the membrane is not impaired and the mode of operation of the valve is not disturbed »radial grooves 13 are seen on the inside of the lid, which can optionally be supplemented by a circular groove 14, which ensures that each other auoh can compensate for the pressure difference between the inflow 11 and the tree above the valve cone when the valve is open.
