Liquid tank spillage control system |
摘要 |
A spill control device for underground liquid storage tanks having an upwardly extending fill pipe. The control device comprises a steel, epoxy coated, liquid collecting spill tank having a riser tube that extends upward through the tank bottom. A circular seal ring fits about the upper end of the riser tube and about the outer wall of a fill pipe received through the riser tube. A clamp compresses the seal about both the riser tube and fill pipe. A liquid impermeable cover is provided which covers the access opening in the top of the spill tank. A first basin surrounds the cover for channeling precipitation, and other liquids impinging the cover, away from the spill tank. A valve is disposed on the fill pipe for selectively directing liquids discharged into the spill tank into the storage tank. A second basin surrounds the spill tank for recovering liquids discharged from the spill tank during a filling operation.
