Be- und EntlüftungsventilVentilation valve BeschreibungDescription

Be- und Entlüftungsventil nach aerokinetischem Prinzip mit zentrischem Schwimmkörper und einer Ventilgarnitur, die im oberen Ventilbereich vertikal angeordnet ist, wobei die Ventilgarnitur (1) aus zwei Zonen zusammengesetzt ist, nämlich aus der Durchströmungs-Zone (2), bestehend aus porösem, luftdurchlässigem Werkstoff und der Abdichtungs- Zone (3), bestehend aus homogenem WerkstoffVentilation and venting valve based on the aerokinetic principle with a centric floating body and a valve assembly which is arranged vertically in the upper valve area, whereby the valve assembly (1) is composed of two zones, namely the flow zone (2), consisting of porous, air-permeable material and the sealing zone (3), consisting of homogeneous material

Bekannte Be- und Entlüftungsventile (z.B. GM 299 03 669.3) nach aerokinetischem Prinzip mit vertikal angeordneter Ventilgarnitur und Rollmembrane sind mit einer Ventilgarnitur als Hohlzylinder ausgebildet, der mit radial angeordneten Öffnungen versehen ist. Diese Öffnungen sind als Bohrungen oder Schlitze ausgeführt und haben eine runde, quadratische, rechteckige oder dreieckige Form.Known ventilation valves (e.g. GM 299 03 669.3) based on the aerokinetic principle with a vertically arranged valve assembly and rolling diaphragm are designed with a valve assembly as a hollow cylinder that is provided with radially arranged openings. These openings are designed as holes or slots and have a round, square, rectangular or triangular shape.

Nachteilig dabei ist, daß die Rollmembrane im Schließzustand des Ventils durch den anstehenden Differenzdruck in diese relativ großen Öffnungen eingedrückt wird und an den Eindruck-Kanten die Rollmembrane verletzt werden kann.The disadvantage here is that when the valve is closed, the rolling diaphragm is pressed into these relatively large openings by the existing differential pressure and the rolling diaphragm can be damaged at the indentation edges.

Die Neuerung beseitigt diesen Nachteil, indem die vertikale Ventilgarnitur (1) aus zwei Zonen besteht, nämlich aus der Durchströmungs-Zone (2) und aus der Abdichtungs-Zone (3) Die Durchströmungszone (2) hat eine feinporige Oberfläche, auf der die Rollmembrane (4) aufliegt, ohne in Vertiefungen eingedrückt zu werden. Verletzungen der Rollmembranoberfläche sind dadurch ausgeschlossen.The innovation eliminates this disadvantage by making the vertical valve assembly (1) consist of two zones, namely the flow zone (2) and the sealing zone (3). The flow zone (2) has a fine-pored surface on which the rolling membrane (4) rests without being pressed into recesses. Damage to the rolling membrane surface is therefore excluded.

Die Abdichtungs-Zone (3) aus homogenem Werkstoff ist im oberen Ventilbereich angeordnet und schließt das Ventil, sobald es von der Rollmembrane (4) überrollt wird, dicht ab.The sealing zone (3) made of homogeneous material is arranged in the upper valve area and seals the valve tightly as soon as it is rolled over by the rolling diaphragm (4).
