Calorimetric target waterway and target plate opening and closing structure based on magnetofluid vacuum sealing

The utility model discloses a calorimetric target waterway and target plate opening and closing structure based on magnetofluid vacuum sealing. The device comprises a calorimetric target structure, asupporting structure, a calorimetric target plate, an opening and closing structure, a vacuum sealing flange, a magnetofluid sealing cavity, a driven gear, a multi-layer water pipe serving as a rotating shaft, a water outlet connector, a water inlet connector, a driving stepping motor, a driving gear, a calorimetric water outlet converging cavity, a water-cooling oxygen-free copper plate, a wateroutlet copper pipe, a water inlet pipe, a rotating pulley, a limiter and a rotating bearing. The lifting calorimetric target with the measuring target relative to the disc telescopic structure has thebeneficial effects that the driving power is small, the size and height of the driving mechanism are greatly reduced, the gravity center is low, and the installation is safe and convenient. 本发明公开了一种基于磁流体真空密封的量热靶水路及靶板张合结构，它包括量热
