FLUID STORAGE SYSTEMS

摘要

A simple modification to a fluid storage system e.g. a central heating system involves incorporating a float member (21) in the header tank (10). The float member is connected to the inside of the tank (10) and floats on or near the surface of the fluid (11) in the tank (10). The tank (10) has an inlet (18) and an outlet (12). A plug (22) is supported on the float member (21). In the event of a sudden fluid leakage in the system the level of the fluid (11) in the tank (10) falls quickly, the float member falls with the fluid, dislodging the plug (22) therefrom. The plug (22) is carried with the fluid in to the outlet (12) of the tank (10), blocking it and substantially preventing further fluid loss therefrom. This minimises the volume of fluid escaping and hence any damage caused is kept to a minimum.
