Description

The present invention relates to a pressure regulating valve and a carbon dioxide gas supply system used when supplying carbon dioxide gas to a beverage container to supply a sparkling beverage such as beer or a beverage such as juice to a dispenser, server, or the like.

When supplying sparkling beverages such as beer to a beer server, carbon dioxide gas is supplied from a carbon dioxide gas cylinder through a pressure reducing valve to a beverage container such as a beer barrel, and the pressure of the carbon dioxide gas is used to generate beer connected to the beer server. It is being pushed out into the flow path. In this case, the appropriate carbon dioxide pressure generally differs depending on the type of beer and temperature. Therefore, in order to supply multiple types of beer, it is necessary to provide multiple types of carbon dioxide gas pressures accordingly. In order to meet such a purpose, an example of a beverage supply device equipped with a plurality of carbon dioxide gas cylinders is described in Patent Document 1.

Furthermore, in dispensers and servers for carbonated beverages, etc., carbon dioxide gas is supplied to carbonators and syrup containers, and the pressures of carbon dioxide gas therein are also different. An example of a beverage dispenser is described in US Pat. Furthermore, when supplying a plurality of beverages, it is necessary to supply carbon dioxide gas pressure corresponding to each beverage.
