A water jet condenser with multiple closed water chambers and a jet flow adjusting valve used in a sugar refinery. A water chamber of the condenser is divided into an open big water chamber (6) and a plurality of closed small water chambers (14); each water chamber is respectively provided with an jet nozzle (3) and a spray nozzle (7); the plurality of closed small water chambers are respectively controlled by a plurality of pneumatic or electric butterfly valves (4) installed outside the condenser; the lower part of the condenser body (13) is provided with a single-layer or multi-layer jet flow adjusting valve (2) for keeping the concentric change of the diameter of the central round aperture of a jet flow passage; the jet nozzle (3) and the spray nozzle (7) in each water chamber are respectively cooperated with the single-layer or multi-layer jet flow adjusting valve (2) to perform adjustment according to the water supply entering the condenser, thereby enabling the high-efficiency water saving while keeping a high vacuum degree of the condenser during the production. |
