Abstract
A double-walled tank for storing liquids, such as heating oil, diesel fuel and lubricating and hydraulic oils, with an inside container 1 made of plastic, and an outside container 2 made of steel sheet, the outside container being provided with a container cover 6. The container cover 6 contains openings for receiving sockets 7 of the inside container 1, and has a collar 8 with a U-shaped cross section. The collar is mounted on the top edge of the container jacket and solidly joined with container jacket 3. The interior space of the collar 8 contains a seal for sealing the collar gas-tight against the container jacket 3. Pressure rings for applying pressure to seals are threaded on sockets 7, and compress the seals between the cover and the container.
Claims18
A double-walled tank for storing fluids such as heating oil, diesel fuel and lubricating and hydraulic oils, with an inside container 1 made of a plastic material, and having inlet and outlet sockets 7, and an outside container made of a sheet-metal, whereby the outside container 2 defines a container jacket 3 having an exposed top edge, comprising;
- a) a container cover 6 having along its periphery a collar 8 with a U-shaped cross section, said collar being mounted on the top edge of container jacket 3 so that the U-shaped collar encloses the top edge of container jacket 3, said cover 6 having openings for receiving sockets 7;
- b) a seal 9 disposed in the interior space of said collar 8 for sealing said collar 8 gas-tight against container jacket 3, seals 15 surrounding said sockets and disposed between said cover 6 and inside container 1;
- and
- c) pressure rings 14 coupled to sockets 7 for applying compressive pressure to seals 15, said pressure rings surrounding sockets 7 in the form of rings.
