摘要： An exemplary embodiment of the present techniques provides a system for decreasing a temperature of a fluid. The system includes an axial flow expander for expanding gas flowed in a direction along an axis thereof. The axial flow expander includes: an outer casing made as a unified structure having an inlet port and an outlet port. An inner casing is fixed inside the outer casing. A rotor shaft is accommodated inside the inner casing, and is aligned with the axis. A number of bearings allow the rotor shaft to rotate around the axis. Moving blades protrude from the rotor shaft and are arranged inside the gas passage in an alternating fashion with a number of stator vanes. The inner casing, the rotor shaft, the bearings, the stator vanes, and the moving blades are integrally assembled, and inserted into the outer casing in the direction along the axis.

摘要： A valve device includes a valve rod connecting a valve main body and a piston and capable of advancing and retracting in a first direction integrally with the valve main body and the piston, a rotary sleeve rotatably supported on a valve casing in a first circumferential direction around a first center axis, an operation member configured to rotate an operation shaft in a second circumferential direction, an advancing and retracting sleeve immovably fixed to the valve rod and the piston, and a stopper member configured to restrict an amount of movement of the advancing and retracting sleeve toward a first side in the first direction. The operation shaft is connected to the rotary sleeve such that a rotation of the operation shaft in the second circumferential direction can be converted into a rotation in the first circumferential direction and transmitted to the rotary sleeve. The advancing and retracting sleeve is movable in the first direction when the rotary sleeve rotates in the first circumferential direction. The stopper member is capable of coming into contact with the advancing and retracting sleeve when the advancing and retracting sleeve moves toward the first side in the first direction by a specified value.
