Title:
CENTRIFUGAL COMPRESSOR AND MULTISTAGE COMPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/110129
Kind Code:
A1
Abstract:
This centrifugal compressor is provided with: a suction valve (12) which is provided on a suction-side flow path (10a) that is a flow path on the suction side of a centrifugal compressor body (13); a bypass flow path (15) which has both ends respectively connected to the front side and the rear side, in the suction-side flow path (10a), of the suction valve (12); and an auxiliary valve (16) which is provided on the bypass flow path (15) and which has a smaller Cv value than the suction valve (12). By using the centrifugal compressor, great pressure loss is assuredly achieved, and thereby, the activation power of the centrifugal compressor can be assuredly reduced.
