Description

Flow valve

The Toe flow meters used in measurement technology are in Most sizes from an internally conical glass tube in v / elchem a float indicates the line flowing through the glass tube.

The conical glass tubes are in practice in a Sohrarnatur installed and in this condition built into the pipeline On the one hand, this fitting serves to protect the handle • and on the other hand for installation in the pipe system.

When replacing a defective glass tube or changing one for another, e.g. changing the first reading area, the entire valve must be removed from the line and unscrewed will. This often results in considerable time losses.

Of course, fittings are known in which they are expanded - Sum expansion, a glass tube - not required from the line is because the glass tube is spring force inside the .t-temperature is supported and sealed. However, there is the use of feathers not always useful as they have to be relatively strong to seal securely; a circumstance that occurs when replacing a G-I pipe often contributes to the fact that the glass tubes burst leg misjudged respectively. to be damaged.

Since these springs are made from spring steel, they are nuts Corrodes very quickly, especially in the chemical industry.

In the present construction, the Yerv / endring is deliberate dispensed with springs or resilient parts to this disadvantage to get rid of.

In the embodiment shown in the attached sketch, in which only one side of the valve is shown, the Fig. L) means the lower connection piece with a screwed ITute Fig. 2), into which the bowls Fig. 3 and 4) rushed their V. Fig. 3a) snap into place. They are held together in this position by the Seeger ring Fig. 11). This is a secure and firm connection of the two shells Fig. 3 and 4) with the ^ connecting piece Fig. L) guaranteed.

Claims (1)

The glass tube Fig. 7) or the float or float Fig. 12) can be observed through the two cutouts H ^{1 Ig. 5 and 6) in the bowls Fig. 3 and 4)} ) the movement of the ileßscliwinnier Fig. 12) is limited downwards. The pressure-tight connection of the glass tube with the fitting is made by the pressure ring Fig. 9)? i * ¹ - which has an O-ring Fig. loa) embedded above, which seals the glass tube, while the lower O-ring Fig. Io) takes over the sealing of the fitting. The expansion of a glass tube is now simply done in such a way that the two shells Fig. 3 and 4) are removed by loosening the circlip Fig. 11), then the pressure ring Fig. 9) is pushed up so far that the edge "B" of the Pressure ring lies in the plane of the line ".-J ¹ and the glass tube can now be pulled out. When a new glass tube is axed in, the order is reversed. The same applies to the upper connection head. Schuta entitlement da3 the le £ glass tube Fig. 7) by a displaceable pressure ring Fig. 9) by means of O-rings Fig. Io and loa) with the connection head Fig. 1) easily detachable, pressure-tight connected is.
