A pressure plate (10) for fitting in a pipe from a container for the storage of liquids is designed to prevent the liquid passing from the container past the pressure plate and out through the pipe.The pressure plate (10) consists of a holder (11) with a passage (13) and a plate (14) fitted closely into this, which is supported by the holder in a groove (15) facing towards the container, so that the effect of a pressure in the direction (A) towards the container, which exceeds the static pressure in the container, moves the plate (14) out of position and opens the passage (13).<IMAGE> |
