FLUID-MACHINERY INSTALLATION DEVICE

PROBLEM TO BE SOLVED: To install fluid-machinery such as power-generation equipment, an impurities-removing device, etc. favorably in the aspect of installation, and conduct maintenance work easily and efficiently. SOLUTION: In a housing A of the fluid-machinery installation device, a first connection-pipe part 2 capable of communicating with an upstream fluid pipe 1A and a second connection-pipe part 3 capable of communicating with a downstream fluid pipe 1B are provided. The housing A is partitioned into a first chamber S1 communicating with the first connection-pipe part 2, a second chamber S2 communicating with the first chamber S1 and the second connection-pipe part 3, and a third chamber S3 which communicates with the first and second chambers S1, S2 and is capable of installing the fluid machinery. The fluid machinery installation device includes a valve device C which is capable of switching between a first flowing state, a second flowing state, and a passage-shutoff state. In the first flowing state, the fluid, which has come in the first chamber S1 in the state that the communication with the third chamber S3 is cut off, is conducted into the second chamber S2. In the second flowing state, the fluid, which has come in the first chamber S1 in the state that the communication between the first and second chambers S1, S2 is shut off, is conducted to the second chamber S2 by way of the third chamber S3. The valve device C is capable of switching to the state of the conduit being shut off wherein at least the communication between the first chamber S1 and the second chamber S2, and the communication between the first chamber S1 and the third chamber S3 are respectively cut off.
