Abstract
This invention involves a liquid-liquid separation device, which includes a centrifugal cylinder. The centrifugal cylinder maintains a liquid inlet/outlet, and centripetal float valve inside, which is mounted on the wall of a cylinder that produces the centrifugal force. Liquids of various densities enter the centrifugal cylinder; under the action of centrifugal force, the liquid medium of the highest density moves to the cylinder wall first, while the liquids of lower densities follow in sequence; when the inward buoyant force that the float bears in the liquids of various densities is greater than the outward centrifugal force generated due to its own mass, the float will move inwards to open the passageway and discharge the heavy medium deposited on the cylinder wall, thus achieving the automatic separation.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
