Abstract
A safety flow control device in a beverage distribution system using pressurized gas to dispense the beverage from its containers for ensuring that the containers are not accidentally overpressurized. The device is adapted to be placed in the line which connects the pressure source to the container for the beverage. The device includes a base assembly having an internal chamber in communication with a fluid inlet and a fluid outlet and a replacement unit removably connected with the base assembly. The replacement unit embodies a rupture disc having a first side exposed to the gas used in pressurizing the containers and a second side exposed at atmosphere. Strategically positioned between the pressure inlet of the device and the pressure side of the rupture disc is a valving mechanism which is maintained in an open configuration by the rupture disc. In the open configuration the valving mechanism permits the gas to flow from the inlet into a first sub-chamber defined by the first side of the rupture disc and then outwardly through the outlet of the device. When the rupture disc fails, the valve mechanism will automatically close preventing further flow of gas into the first sub-chamber and toward the outlet. The replacement unit is constructed as at unit of the factory so that, when the rupture disc fails, the entire unit containing the failed disc can be disassembled from the base assembly and replaced with a factory built replacement unit having a new rupture disc correctly positioned therewithin.
