查询词典 pressure turbine

The process of vapor pressure reducing was achieved through decompression valve and throttling disk. Centrifugal nozzles were installed along the circumference to makewater sprayed more uniform and atomization effect better. The atomization could be optimized and heat transfer between water and vapor was intensified in Ventri.
