Check valve.

Addendum to patent 201596 of November 12, 1907.

Patented in the German Empire on December 4, 1908 "from. Longest duration: November 11, 1922.

The subject of the invention is a further development of the patent protected by 201596 Device for tapping pressurized liquids, to the effect that with the involvement of an already the non-return valve used in the subject of the main patent between the tapping bung and pressure medium line the branch pipe leading from the latter to the outlet pipe branched off in front of the check valve from the part of the pressure medium line located between this and the pressure medium container and at the connection point between the outlet pipe and the branch pipe the pressure medium line switched on the multi-way tap, which used to be the tap at the same time a riser pipe leading to the special tap is connected. This facility proves in particular useful for devices for dispensing beer where the stopcock is arranged within the counter. When opening the multi-way tap mentioned a pressure equalization is established in the entire pipeline system, and not only. those in the liquid line below the multi-way tap, but also those in the riser pipe Above the multi-way valve existing column of liquid falls into the barrel because

when opening the branch line after the outlet pipe the carbonated liquid present in the riser pipe with the pressurized gas (Carbonic acid) mixes and by separating the gas and liquid particles the density the liquid is lifted and the liquid particles sink. So it is the stopping of beer in the tap when the tap is interrupted is excluded, in addition, if there is an unauthorized tapping attempt after pressure equalization has taken place not the liquid, but the pressure medium from the open tap to the outflow.

The drawing illustrates in Fig. 1 schematically the overall arrangement of a after the operating system executed according to the invention with an open multi-way valve. Figures 2 and 3 show two embodiments of the mediating the connection between branch pipe and outlet pipe and interrupting valve in the closed position.

The riser pipe 3 inserted through the tapping bung 2 into the barrel 1 is connected by the branch pipe 3 'to the line 6 which leads from the pressure source α to the nozzle f of the tapping bung 2 containing the check valve. The branch pipe 3 'leading to the riser 3 is in front of the connector f containing the check valve from the one between the pressure medium container α and the

Claims (1)

Check valve located part of the pressure medium line 6 is branched off, and a riser 12 'is connected to the connection point of the branch pipe 3' with the riser 3, a riser pipe 12 'which leads to the tap 12 ". The port cock 12 or 8 can, as 2 and 3. In the first-mentioned case, the valve body 8 provided with the bore 13 is in the connecting line 3 '(FIG. 2), in the latter case the one with the bores 13, 14 provided faucet body 8 in the connection point between the riser 3, in which a pipe coil can be connected in a known manner, the riser pipe 12 'and the branch pipe 3' (Fig. 3) at a point easily accessible for the operator of the apparatus installed inside the counter (Fig. 1). Between the connection 2 and the pressure line 6, as in the subject of the main patent, there is a non-return valve f, which is located when a put the dispensing device in the barrel 1 closes automatically and prevents liquid loss due to the liquid entering the pressure medium line. In order to fill the liquid contained in the container 1, the tap body 8 brought into the position shown in Figs. 2 and 3, so that the tap hole 14 the Connection between the pipes 3 and 12 'establishes (Fig. 3) or the branch pipe 3 'against the dispensing line 3, 12' is completed (Fig. 2 and 3) and when it is open Tap the liquid as a result of the pressure acting on the liquid level exits the container 1 through the pipes 3, 12 'and the tap 12 ". Desired on the other hand, the tapping for a longer period of time, e.g. B. for the duration of one night, are interrupted, as shown in dotted lines in Fig. 2, the valve body 8 to 90 ° or rotated 180 ° according to FIGS. 3 and 1, so that in both cases the connection of the branch pipe 3 'is made with the line 3, 12' and with the tap closed 12 ″ in the entire pipe system 3, 3 ', 6 a pressure equalization takes place. Simultaneously with The column of liquid in the line 3 also drops the column of liquid in the riser pipe 12 ' Liquid in the barrel ι down, since when the branch pipe 3 'is opened, the outflowing Carbonic acid with the also containing carbonic acid present in the riser 12 ' Liquid column mixes and by separating the gas and liquid particles the Density of the liquid is canceled. The entire line is therefore filled with the pressure medium, for example with Carbonic acid, so that in the event of any unauthorized attempt to draw off any liquid, but the pressure medium itself emerges from the tap 12 ″. The device i accordingly offers the advantages that liquid losses when plugging in as well as unauthorized tapping are excluded as far as possible, and that as a result of the filling of the entire pipe system with carbonic acid the formation of organisms within the pipe is prevented as far as possible. PateNT-AνSPRUcη: Device for tapping pressurized liquids with a check valve according to patent 201596 switched on between the tapping plug and the pressure medium line, characterized in that the branch pipe (3 ') leading from the pressure medium line (6) to the riser pipe (3) is upstream of the check valve from the between the pressure medium container (α) and the non-return valve containing the nozzle (f) located part of the pressure medium line (6) branched off and a valve (12) switched on in the connection point between branch pipe (3 ') and riser / pipe (3) Tap (12 ") leading riser pipe (12 ') is connected, which is emptied together with the riser pipe (3) when the pressure equalization is established. For this purpose ι sheet of drawings.
