Device for reducing the pressure "in beverage dispensing systems

The innovation relates to a device for reducing the pressure in beverage dispensing systems, which with a below
Pressurized gas, such as CO 2 or the like, can be operated. Such devices usually have a housing in which connections for the pressure gas, for a content manometer, an adjustment valve, a safety valve,
a working manometer or the like. Are provided.

Such pressure reducing devices for beverages oind in
different versions known. In one design, the working manometer, which is used to display the pressure in the low-pressure line, is at the top and the pressure gauge is at the top.

Y% .:" f ^: ?; ', Sis a T-piece attached to the side of the housing, which is ' ■'% .; ^, The CCL safety valve and the screw-down valve are used. The CO ^ safety valve is an overflow valve which can be set to a certain pressure and which fades when the set pressure is exceeded. The lower

C screw cock, which is arranged in the low pressure line is also used to shut off the pressurized gas when changing a beverage container

In the case of the side-mounted content manometer, the Niedereehraubhahn can be attached to the bottom of the housing, but a transition piece must be screwed onto the top of the housing to accommodate the COg safety valve and the working manometer. This is necessary because the entire pressure of the COg bottle, which is approximately 50 to 60 atmospheres, is fed into the pressure reducing device. When expanding these known devices to batteries with one or more intermediate pressure binders, as is the case for the different types of beverages, such as i. B. Beer, CoIa ₁ shower and the like. Is necessary, it is necessary to provide a safety valve for monitoring the pressure for each intermediate pressure child.

Xs lit the task of innovation, the lack of the above ale known devices described for reducing the pressure in beverage dispensing systems and in particular a «possibility to create the expansion of this device for several, possibly different high pressures allowed. In addition, the arrangement of the various instruments of the performance is to be improved and brought to a Perm which is more useful and convenient for use.

All this will be done with one task to reduce the pressure in beverage dispensing systems, which is characterized by a connection that can be closed or shut off and is connected to the low pressure valve located in the flow direction Mater des Sisstsllrsntil »When expanding the device _ ^ tion for the various types of beverages that may be ^ Make the prints from one another aVreichH.de necessary, An intermittent pressure reducer can be connected to this connection without any further connection. It is also so-called borrowed, also other ZTischdruckmindtrers without their own To connect the safety valve downstream of the main pressure reducer

For the purpose of further reducing the working pressure, there is an intermediate pressure gauge , a connection to the beverage container, an outlet valve and a further connection that can be worn or shut off.

pressure reducer provided "which is connected to the low-pressure tank or the connection of the main pressure reducer via a connection" line. In this way, several intermediate pressure reducers can be connected downstream of the main pressure reducer. This special design makes it possible to dispense with safety valves in the intermediate pressure reducers, since "Moral drink * / ~ \ lines via the one safety valve of the Eau.ptdruck" reducing device are secured. It is only necessary to ensure that the maximum pressure

ren built-in intermediate pressure regulator each stepped to be set to a different pressure. The main pressure adder prevents all interim pressure from being exceeded for all connected persons Pressure as the safety valve on the main pressure regulator deflates.

Another advantage of the innovation is that it is functional Arrangement of the intermediate pressure reducers next to one another. This enables a clear construction, the essential advantages for practical operation ■ it brings.

The idea of innovation allows xm individual different constructive configurations xs. It is exemplified in the accompanying drawings, namely

demonstrate:

Tig. 1 the device according to the innovation for only one Pressure stage of two low-pressure lines, each cut,

2 shows a section along the line II-II in Pig, I,

Fig. 3 is a similar view as in Fig. 1, but with the connection of an intermediate pressure reducer to the Main pressure reducer.

In Fig. 1, the device according to the invention is shown. In a housing 1 siad. several connections 2 to 7 are provided. Λμ connection 2, the GQ _Ö bottle is connected via an intermediate piece. The intermediate piece 8 has in a per se known / *% ¥ * ise a sieve for the CO ^ -druckgas.

The connection 3 is intended to accommodate the content anometer 9. The COg safety valve is screwed in at connection h , and the working manometer is housed in connection 5 , while connection 6 is the connection to. the low pressure lines 12 and 13.

I »Housing 1 is a high pressure cask 14 and a low - dracJdcajoier 15 gate-seen, which are widely ramified

According to the innovation as housing 1 is a further connection 7 C provided, which is normally provided with a sealing screw 18

is closed * When checking the pressure reducer bsw. of the working manometer 11 is the test manometer connected · This makes it easy to check the working pressure, as both the working pressure gauge 11 and the test manometer are connected to the low-pressure chamber 15 via the intermediate piece 24.

The connection 7 is also suitable for connecting one or more intermediate _{pressure reducers 19 to the housing 1 bcw c} to the low-pressure chamber 15. Different pressures are required when different types of beverages are to be served. In Fig. 3, therefore, the connection of an intermediate pressure reducer 19 to the connection 7 via an intermediate piece 20 is shown. The intermediate pressure reducer is equipped with a content manometer 11 *. At the bottom a connection 6 'is provided, which branches into two further low-pressure lines 21 and 22. The central pressure reducer 19 also has a further closable connection 23, which per se fulfills the same purposes and functions as the connection 7.

The path of the CO ₂ or some other compressed gas in the device is more detailed:

Through the A * Schlnß 2 enters the compressed gas, which below henea pressure is in the housing 1 and arrives at Hechdruckkaraer 14. The content maneaeter 9 is “it the High pressure Kanffiier 14 in connection and therefore shows the Pressure in the pressurized gas cylinder «. Tem of the high pressure chamber 14 the pressurized gas arrives in a corresponding pressure reduction Via the adjusting valve 16 into the low-pressure tank 15 (Fig. 2). The Niederdruckkaiamer 15 has connection old that Safety valve 10, which all low pressure lines 12, 13, 21, 22, etc. ensures that the work meter becomes 11 the pressure of the low pressure camera 15 is displayed. On the The connection 6 is reached by means of the adjustment valve 16 set pressure via «* in intermediate piece 24, which is expediently provided with a low valve 25, to the low pressure lines 12 and 13.

When one or more intermediate pressure regulators 19 are connected, the intermediate piece 20 provides the connection to the Niederdmekkamaer 15 b «? ₌ Α »? Ϊί is is in the same way · as in the pressure reducing device, i. H. in the Hauptdruelmiaderer, an adjusting valve 16 * provided through which the pressure can be further reduced.
