摘要

The device for preventing the escape of water does not endanger water-soluble liquids having densities of less than water are, in particular for heating oil, from above-ground storage containers the latter is flooded by floodwater.With respect to the prior art, with the apparatus according to the invention, the stresses acting on heating oil container by means of pressure - and anchoring the latter is flooded by floodwater reduced considerably. This objective of the invention is achieved by a flooding of the container with a flood pipe line is achieved by means of a jack.A filled with water or with heating oil and deaerated jack tube line, which begins in a water-filled upright tube and, after being guided over the container apex is within the heating oil container ends and is tightly closed on both sides with closure elements, it is only in the case of buoyancy of the container or in the case of a still safe external pressure on the container walls by means of pneumatics - or hydraulic valves for flooding of the container is opened with high water. By means of a traffic jam closure fitting on the upright tube, the high water flows to the open jack tube line and flows to the pressure compensation in the container. In the case of reduction of the high water, blocks the return movement of the traffic jam closure fitting the return flow is carried out automatically, so that the project into the container, flood go berte only over the upper opening of the upright tube can flow back, the height of a few centimeters above the maximum filling level of the heating oil container is.The device is suitable for a high water secure installation of heating oil containers in to tell spaces which lie in or by build-up of water or water pipe break can be flooded.n="9"
