Description

  The present invention relates to a liquid transport device connected to a liquid filling machine that fills a container such as a beer or a soft drink into a barrel or the like, and in particular, when the liquid is transported to the filling machine, the pressure fluctuation of the liquid is reduced. The present invention relates to a liquid transport device.

  When filling a container such as a barrel or the like with a liquid such as beer or a soft drink through a liquid filling machine, if the supply pressure of the liquid to the filling machine fluctuates, the filling accuracy decreases. For this reason, it is necessary to connect a liquid transport device to the liquid filling machine in order to reduce the fluctuation of the supply pressure.

In the liquid filling machine 1, a barrel 2 for filling a liquid is disposed, and a cushion tank 20 (liquid for filling machine) is provided via a transport pipe 3. Transport device) is connected. In FIG. 2, 4 is a flow meter, 5 is a valve, and 21 is a visual pressure gauge.

  For example, when the liquid to be filled is beer, the inside of the cushion tank 20 (liquid transport device) is pressurized with carbon dioxide gas, and the pressure of the liquid is controlled by precisely controlling the gas pressure with the gas pressure control valve 22. I was holding it small. Reference numeral 23 denotes a liquid level gauge.

However, the above-described known liquid transport device requires a large tank as the cushion tank 20, and further requires a gas pressure control valve 22 and a liquid level gauge 23. Furthermore, the gas pressure control valve 22, liquid level gauge is required. 23, The main body of the tank 20 needs to be sterilized and cleaned, which requires a large cost.
