IMPERIAL

PATENT OFFICE.

The previously known Mefs- and Abschheilungsapparate for liquids or gases, which one exposed to high pressure and intended to remove small quantities of liquids from the Separating main containers failed because of the impossibility of keeping these apparatuses leakproof. The great pressure exerted by the liquid naturally penetrated it in one such constantly used intermediate apparatus often present sealing surfaces.

This tight seal is to be achieved by the use of a hollow spindle, described below, which is movable in its axial direction and at the same time temporarily serves as a valve seat for a valve body, which is axially connected to a second valve body with the engagement of a dead passage. As a result of this combination, the hollow, axially movable spindle forms the drain pipe for the measured quantity of liquid in one position, while when it is moved down it acts as a valve seat for the valve ν and thereby closes the Mefsbehä'lter m in both directions, because on the other hand the valve v ¹ still rests firmly on its seat s ^1. Only when the spindle ρ continues to move down is the valve v ¹ , which closes the Mefsbehälters m against the supply pipe \ (from the main container), raised, and a new quantity of liquid can now enter m and fill it.

During this liquid supply period, the valve ν remains closed due to the constant axial movement of the spindle ρ. The seal is made by the spring y and by the excess pressure of the liquid.

When moving up the also ^one beeinflufste valve first sets of a Federy v ^l on his seat, so slept the Mefsgefä'fs against the feed tube% for liquid from, and only with continued upward movement of the spindle, the bore lifts from the valve plug ν, and the measured quantity of liquid can be consumed further, e.g. B. It can be used by evaporation, for the preservation and cooling of beer and for other purposes. It is readily apparent that this central arrangement of all parts, this axial movement, raising and lowering of the hollow spindle serving as the valve seat and of the valves must produce a constant, secure seal even under great pressure; all rubbing sealing surfaces in the parts under high pressure are avoided, as are all eccentric or sudden movements of the valves; the whole arrangement and mode of operation consists in a gradual raising and lowering of the valves and spindle.

Fig. 1 shows this Mefsapparat in longitudinal section, g is the tubular housing which encloses the actual Mefsbehälters; it is closed on the one hand by the valve v ^l and the valve seat s ^x and covered by an elbow k , to which the pipeline ^ connects, which leads to the container of the

Liquid leads. On the other hand, the housing is completed g of the pipe section r, in which the hollow spindle by ρ y gland packing in a known manner ¹ is mounted tightly.

This hollow spindle, as shown in the drawing, can be arranged so that it can be axially moved and depressed by means of the thread i. The depression is then carried out by turning the spindle, or this axial movement of the hollow spindle can also be achieved without turning by pressing the spindle down from the outside.

The end opening of the hollow spindle also forms the seat for the valve v, which the latter is always brought closer to the seat by spring f.

The shut-off valve v ^{l is} connected to the valve body ν by sleeve e , so that with axial movement of the valve ν it lifts against the knee-shaped pierced valve ^{pin v 2} , the latter and thus also the valve v ¹ firmly connected to it. The valve v ¹ is also always pressed onto its seat by the spring f ^l.

It should also be mentioned that the bore of the spindle ends outwards at w and opens there into the switched-on pipe socket r ¹ , to which the line α for the outflowing gas closes.

The effect and handling is as follows: The hollow spindle is in the highest position shown; the valve v ^l closes tightly, pressed by the spring f ¹ and the tension prevailing in the pipe % , on its seat s \ while the valve ν is freely lifted from the screwed-up seat s. The vessel m is therefore connected to the discharge pipe a .

If you move the upright hollow spindle downwards, the seat is first firmly seated against valve v, and the measuring chamber m is closed on this side against the discharge pipe a , with further movement the. Spindle ρ ν with the valve body downwards; so that the same applies to valve pin schliefslich v ^2, and therefore this also moves the valve downwards, ie the valve from its seat v ¹ s ¹ lifts. It now flows through pipe ^ the left under grofsem pressurized gas or liquid into the Mefsgefäfs in and fills the same. If one now moves the spindle in the opposite direction, i.e. upwards, the opposite effect takes place; it is first the valve v ¹ on its seat while the valve ν is still closed.

At this moment the measuring vessel m is closed on both sides, and only with further movement from ρ upwards does the valve v open, and the measured liquid from m enters the outlet a ¹ and creates a certain pressure in this outlet .

In this way the present Mefsapparat from a under high pressure Any lower pressure generated in a second vessel in a standing vessel is maintained and enlarged as desired, as is the case in the industry, e.g. B. when using Liquid carbonic acid for the most diverse purposes of serving beer and producing mineral water u. s. w., necessary and desirable, is worthwhile.

FIGS. 2 and 3 show the use of this measuring and dividing apparatus for beer dispensing purposes.

I is the Bierfafs into which a tapping cock h known construction is stamped. At this tap on the one hand in Fig ι. Mefsapparat M shown sitting assumed its Zuflufsrohr for the liquid carbon dioxide at £ and whose Abflufsrohr is α. This drain pipe α leads directly into the tap, which is open at the bottom. In order to prevent bumps when the measured quantities of carbonic acid are supplied to the manometer to be attached, a small air chamber d with an attached safety valve is placed in front of the manometer t and this is protected by a hood q . Naturally, the Mefsapparat can also be attached at the top near the tap h ¹ instead of at the bottom of the drum. In the Mefsapparat Fig. Ι both valves ν ν ¹ instead of in one axis can also be next to each other, connected by levers.

In Fig. 4 a modification of the Mefsapparates shown in Fig. Ι is drawn, which differs from the first arrangement only through constructive details.

The displaceable rod ρ has no thread, so it does not turn, but is simply pushed up and down by the lever h, thereby causing the alternating closing and opening of both valves ν ν ¹ . The central channel tv does not end sideways, but at the top at a, at which point the hose line (pressure line) to the beer kegs or. another liquid container. Due to this thoroughly internal arrangement of the channel w , the upper stuffing box y in FIG. 1 is completely omitted.

In addition, the valve v ^{x is provided} with a web guide so that the liquid coming from the carbonic acid container, after lifting the valve v ¹ , can pass the spaces in the web guide f and get into the container m.

As can be seen, this modification works in exactly the same way by gradually increasing

Raise and place both valves ν ν ¹ , with one valve seat being formed by the hollow spindle ρ itself.

Claims (1)

Patent claim: The use of an axially displaceable rod p , which serves as a discharge pipe and forms a valve seat s at its hollow end, in conjunction with two valves ν v \ whose, which can be moved one after the other by the rod, is used on Mefs and departmental apparatus which are exposed to high pressure one of them is seated on the end of the rod for the purpose of alternately closing and opening both valves and thereby causing a certain amount to be supplied and discharged.
