Draining gasoline and water accumulated in the storage tank after a spill, accident, or rain. Explosion-proof design, lid made of intrinsically safe alloy.
The flap is placed on a storage tank, where everything that has been spilled on the site drains: fuel in case of an accident or overflow and rainwater. The device is simple to the limit — a pipe with a hinged lid — and this is its meaning: there is nothing to refuse the mechanism at the moment when it is needed.
The structure consists of a pipe, a cover, a bracket, a flange, a gasket, a folding bolt and a flywheel. To drain the accumulated contents, unscrew the flywheel and flip back the lid; after draining, close the lid and fix it with a bolt. The lid is made of intrinsically safe aluminum alloys, the body is made of steel. Installation and maintenance are carried out only with intrinsically safe tools, and maintenance is prohibited during draining and filling operations.
