Abstract
A valve assembly for filling a bag with a beverage under pressure has a valve body having a first passageway extending therethrough and a first valve seated in the first passageway for controlling the flow of beverage through the first passageway into and out of the bag. A pressure relief passageway extends through the valve body from inside the bag to within the container. A bursting disk is seated with the valve body normally closing the pressure relief passageway and is adapted to rupture permitting fluid to escape from the bag through the pressure relief passageway and into the container surrounding the bag when the pressure in the bag exceeds a predetermined pressure value.
Claims13
A valve assembly adapted for filling a bag with a beverage under pressure where the bag is contained in a container and secured with the valve assembly, the valve assembly comprising:
- a valve body adapted to be secured with the container, the valve body having a first passageway extending through the valve body;
- a first valve seated in the first passageway for controlling the flow of beverage through the first passageway into and out of the bag;
- a pressure relief passageway extending through the valve body from inside the bag to within the container;
- and
- a bursting disk seated with the valve body normally closing the pressure relief passageway and adapted to rupture permitting fluid to escape from the bag through the pressure relief passageway and into the container surrounding the bag when the pressure in the bag exceeds a predetermined pressure value.
An alcohol beverage dispensing apparatus comprising:
- a keg having an aperture;
- a bag contained in the keg for containing an alcohol beverage;
- and,
- a valve assembly to which the bag is secured and comprising:
- a valve body secured in the aperture of the keg, the valve body having at least first and second spaced apart passageways extending through the valve body;
- a first valve seated in the first passageway for controlling the flow of beverage through the first passageway into and out of the bag;
- a second valve seated in the second passageway for controlling the flow of a pressurizing gas through the second passageway into the container and exterior of the bag;
- a pressure relief passageway extending through the valve body from inside the bag to within the container;
- and
- a bursting disk seated with the valve body normally closing the pressure relief passageway and adapted to rupture permitting fluid to escape from the bag through the pressure relief passageway and into the container surrounding the bag when the pressure in the bag exceeds a predetermined pressure value.
