Heat input to the flow paths 11a and 12a in the piping portions 11 and 12 is suppressed by the vacuum layers 21c and 22c. That is, the temperature of the fluid flowing through the flow paths 11a and 12a can be maintained, and for example, the temperature of the liquid can be maintained at an extremely low temperature during transportation of the fluid.
- each of the pair of pipe sections 11 and 12 has valve seats 11e and 12e.
- Valve seats 11e and 12e are formed in flow paths 11a and 12a, respectively. More specifically, the valve seats 11e and 12e are formed on the opening ends 11b and 12b of the flow paths 11a and 12a. Although the valve seats 11e and 12e are formed so as to be connected to the opening ends 11b and 12b in the present embodiment, they are formed away from the opening ends 11b and 12b toward the inside in the axial direction of the piping portions 11 and 12. good too.

- the connecting member 13 is a member that connects the pair of pipe portions 11 and 12 . More specifically, the connecting member 13 connects the butted flanges 11d and 12d. Also, the connecting member 13 can be removed from the pair of pipe portions 11 and 12 . The pair of pipe portions 11 and 12 can be separated from each other by removing the connecting member 13 .
- the connecting member 13 is a clamper. That is, the connecting member 13 connects the pair of pipe portions 11 and 12 by sandwiching the flange portions 11d and 12d. Further, the connecting member 13, which is a clamper, can be removed from the pair of pipe portions 11 and 12 by releasing the clamping of the flange portions 11d and 12d by opening. Note that the connecting member 13 is not limited to a clamper, and may be a fastening member such as a bolt. That is, it is sufficient that the pair of pipe portions 11 and 12 can be connected and detached.
- shutoff valve A pair of shutoff valves 14 and 15 are provided in the corresponding piping portions 11 and 12, respectively. Each of the pair of shutoff valves 14 and 15 shuts off the flow paths 11a and 12a of the corresponding piping portions 11 and 12, respectively. More specifically, each of the pair of shutoff valves 14, 15 has a valve element 23, 24 and a linear drive device 25, 26, respectively.
- valve bodies 23 and 24 are seated on the valve seats 11e and 12e of the corresponding piping portions 11 and 12, respectively.

- the valve bodies 23 and 24 are arranged in the flow paths 11a and 12a. Then, the valve bodies 23 and 24 move from the closed position to the open position along the flow paths 11a and 12a.
- the closed position is the position where the valve bodies 23 and 24 are seated on the valve seats 11e and 12e
- the open position is the position where the valve bodies 23 and 24 are separated from the valve seats 11e and 12e.

- the valve bodies 23 and 24 are configured to be movable along the axis L1 along the flow paths 11a and 12a.
- the valve bodies 23 and 24 do not necessarily have to be configured to be movable along the axis L1.
- the valve bodies 23 and 24 may move along a direction inclined by a predetermined angle (for example, 30 degrees or less) with respect to the axis L1. Such a case is also synonymous with movement of the valve bodies 23 and 24 along the flow paths 11a and 12a.
- valve bodies 23 and 24 are tapered (for example, truncated cone-shaped or step-shaped) toward the distal end side in the same manner as the valve seats 11e and 12e.
- the valve bodies 23 and 24 are tapered like the valve seats 11e and 12e.
- the valve bodies 23 and 24 are then seated on the valve seats 11e and 12e.
- the channels 11a and 12a are closed.
- the outer diameters of the valve bodies 23 and 24 are smaller than those of the flow paths 11a and 12a. Therefore, when the valve bodies 23 and 24 are in the open position, the fluid flows between the flow path 11a of the piping section 11 on one side and the flow path 12a of the piping section 12 on the other side.
- valve bodies 23 and 24 are separated from each other in the axial direction while seated on the valve seats 11e and 12e as shown in FIG. More specifically, the valve bodies 23 and 24 are spaced inside the pipe sections 11 and 12 from the open ends 11b and 12b.
- the end surfaces of the valve bodies 23 and 24 on the side of the opening ends 11b and 12b are separated from the opening ends 11b and 12b to the inside of the piping portions 11 and 12 by predetermined distances A1 and A2.
- the valve bodies 23 and 24 do not contact each other when the pair of pipe portions 11 and 12 are connected. Therefore, the valve bodies 23 and 24 can be seated on the valve seats 11e and 12e while the pair of pipe portions 11 and 12 are connected.
- the valve bodies 23 and 24 can close the flow paths 11a and 12a before the pair of pipe portions 11 and 12 are separated.
- the valve bodies 23 and 24 are positioned inside the pipe parts 11 and 12, a sealed space 31 is formed between them while the valve bodies 23 and 24 are seated. Therefore, the predetermined distances A1 and A2 are set so that the volume of the closed space 31 is equal to or less than the predetermined volume.
- the predetermined volume is 50 liters or less, preferably 20 liters or less.
- the predetermined volume is not limited to the volume described above.
- the direct drive devices 25, 26 move the corresponding valve bodies 23, 24 along the flow paths 11a, 12a to seat them on the valve seats 11e, 12e. More specifically, the linear drives 25, 26 linearly move the valve bodies 23, 24 along the flow paths 11a, 12a between the closed position and the open position. More specifically, each of the linear drives 25, 26 has valve shafts 27, 28 and drive portions 29, 30, respectively.
- valve shafts 27,28 are connected to the valve bodies 23,24.
- the valve shafts 27, 28 extend in a predetermined direction. More specifically, the valve shafts 27 and 28 are long rod-shaped members extending in a predetermined direction.
- Valve bodies 23 and 24 are integrally provided at one end of the valve shafts 27 and 28 in a predetermined direction.
- the valve shafts 27 and 28 are provided on the valve bodies 23 and 24 so that their axes are aligned with each other.
- the valve shafts 27 and 28 are arranged along the axis L1 along which the one end portions of the pipe portions 11 and 12 extend in this embodiment. That is, the predetermined direction coincides with the axial direction in this embodiment. Note that the predetermined direction does not necessarily have to match the axial direction.
- valve shafts 27 and 28 pass through the corresponding piping portions 11 and 12 so as to be slidable in the axial direction. More specifically, valve shafts 27 and 28 pass through elbow portions 11c and 12c of corresponding piping portions 11 and 12, respectively.
- the valve shafts 27 and 28 are provided on the elbow portions 11c and 12c of the piping portions 11 and 12 so as to be slidable in the axial direction. More specifically, the valve stems 27, 28 extend from the valve bodies 23, 24 along the axis L1 to the opposite sides of the open ends 11b, 12b. Therefore, the valve shafts 27 and 28 are outer portions having a large radius of curvature in the elbow portions 11c and 12c and pass through the extension line of the axis L1.
- valve shafts 27 and 28 move the valve bodies 23 and 24 between the open position and the closed position by sliding the elbow portions 11c and 12c in the axial direction.
- the valve stems 27 and 28 slidably pass through the elbow portions 11c and 12c in a sealed state in this embodiment.
- the drive units 29 and 30 axially move the corresponding valve bodies 23 and 24 via the valve shafts 27 and 28, respectively. More specifically, the drive units 29, 30 move the corresponding valve bodies 23, 24 between the open position and the closed position via the valve stems 27, 28. As shown in FIG. More specifically, the driving portions 29 and 30 are connected to the other ends in a predetermined direction (the other ends in the axial direction in this embodiment) of the corresponding valve shafts 27 and 28 . The drive units 29 and 30 linearly move the valve shafts 27 and 28 in the axial direction. That is, the drive units 29 and 30 reciprocate the valve shafts 27 and 28 along the axial direction.
- the drive units 29 and 30 are configured including hydraulic cylinders in this embodiment.
- Drive units 29 and 30 including hydraulic cylinders are connected to a hydraulic circuit (not shown).
- the hydraulic circuit is controlled by a control device (not shown), and supplies and discharges hydraulic oil to and from the drive units 29 and 30 according to control signals from the control device.
- the drive units 29 and 30 move the valve shafts 27 and 28 in the axial direction by supplying and discharging hydraulic oil through the hydraulic circuit. This causes the valve bodies 23, 24 to move between the open position and the closed position.
- the drive units 29 and 30 are not necessarily limited to hydraulic cylinders, and may include, for example, an electric motor and a linear motion mechanism (ball screw mechanism, rack and pinion mechanism, etc.). Anything that can be driven linearly may be used.
- the drive units 29 and 30 are electric motors, the drive units 29 and 30 move the valve shafts 27 and 28 in one and the other axial direction in response to a drive signal from the control device.
- the drive portions 29 and 30 are provided on the elbow portions 11c and 12c of the corresponding piping portions 11 and 12, respectively. That is, the driving portions 29 and 30 are provided outside the pipe portions 11 and 12 . More specifically, mounting portions 11f and 12f are formed on the outer peripheral surfaces of the elbow portions 11c and 12c. The drive portions 29 and 30 are attached to the elbow portions 11c and 12c via attachment portions 11f and 12f. In this embodiment, the valve shafts 27 and 28 pass through the elbow portions 11c and 12c, and the other axial ends of the valve shafts 27 and 28 reach the mounting portions 11f and 12f. The drive portions 29 and 30 are connected to the other ends of the valve shafts 27 and 28 at the mounting portions 11f and 12f.
- the valve bodies 23, 24 are separated from the valve seats 11e, 12e (see FIG. 1) except in an emergency in which there is a possibility that the land facility and the ship are separated by a set distance or more. Thereby, the fluid can be transported via the fluid handling apparatus 1 between the land facility and the tanker.
- the emergency detachment mechanism 2 disconnects one piping section 11 from the other piping section 12 in an emergency, thereby disconnecting the tanker from the land facility. More specifically, in the emergency detachment mechanism 2, in an emergency, for example, a control signal is output from the control device to the hydraulic circuit. As a result, hydraulic oil is supplied to and discharged from the drive units 29 and 30 . As a result, the drive units 29 and 30 move the valve bodies 23 and 24 to the closed position via the valve shafts 27 and 28, respectively. Then, the channels 11a and 12a are closed (see FIG. 2). By removing the connecting member 13 from the flange portions 11d and 12d, the pipe portion 12 can be separated from the pipe portion 11 (see FIG. 3). In other words, one pipe portion 11 can be disconnected from the other pipe portion 12 while the two flow paths 11a and 12a are closed. This allows the tanker to be disconnected from the onshore facility in an emergency while reducing the flow rate of leaking fluid.
- the use of the linear drive devices 25 and 26 allows the valve bodies 23 and 24 to be moved with a large driving force. As a result, even when the pipe portions 11 and 12 have a large diameter, the valve bodies 23 and 24 can be moved against the fluid to close the flow paths 11a and 12a of the pipe portions 11 and 12. FIG. That is, the pipe diameter is increased and the valve bodies 23 and 24 can be closed.
- the valve bodies 23 and 24 can be seated on the valve seats 11e and 12e with the valve bodies 23 and 24 separated from each other. 12a can be closed. Therefore, the flow paths 11 a and 12 a can be closed before the connecting member 13 is removed from the pair of pipe portions 11 and 12 . As a result, the flow rate of fluid leaking from the flow paths 11a and 12a when the pair of pipe portions 11 and 12 are separated from each other can be suppressed. More specifically, the flow rate of the fluid leaking from the flow paths 11 a and 12 a can be suppressed to the volume of the closed space 31 . In addition, since the volume of the sealed space 31 can also be set by the predetermined distances A1 and A2, it is possible to suppress leakage of fluid at an undesired flow rate.
- valve shafts 27 and 28 pass through the elbow portions 11c and 12c, and the driving portions 29 and 30 are provided on the elbow portions 11c and 12c. Therefore, the shorter valve stems 27, 28 can be protruded from the piping portions 11, 12, so that the length of the valve stems 27, 28 can be reduced. As a result, the weight of the valve shafts 27 and 28 can be reduced, so that the size of the driving portions 29 and 30 can be reduced. Further, by suppressing the length of the valve shafts 27, 28, it is possible to suppress axial deviation of the valve shafts 27, 28.
- the emergency detachment mechanism 2 since hydraulic cylinders are used for the driving parts 29 and 30, the emergency detachment mechanism 2 can be used more safely. Furthermore, since the driving parts 29 and 30 are exposed to the outside air, it is possible to prevent the temperature of the hydraulic oil from lowering in order to move the driving parts 29 and 30 when a cryogenic fluid such as liquefied hydrogen is transported. Thereby, the viscosity of hydraulic oil can be ensured.
- the piping portions 11 and 12 are formed in an L shape, but they may be in a straight shape, for example, and the shape does not matter.
- the valve shafts 27 and 28 extend in a direction that intersects the axis of the pipe portion (the inclination with respect to the axis is 30 degrees or less), and move the valve bodies 23 and 24 in the direction that intersects.
- the valve seat is also formed to be inclined in a direction intersecting with the axis of the pipe portion.
- the valve bodies 23 and 24 are both seated and are spaced axially inward of the pipe portions 11 and 12 from the opening ends 11b and 12b. good too. That is, only one of the two valve bodies 23 and 24 may be separated from the opening ends 11b and 12b inward in the axial direction of the pipe portions 11 and 12, and the two valve bodies 23 and 24 are seated against each other. They can be arranged in any way as long as they are separated. Further, in the emergency detachment mechanism 2, it is not always necessary to output a signal from the control device to the hydraulic circuit in an emergency. For example, the emergency release mechanism 2 may be configured such that the valve bodies 23, 24 are moved by manually actuating the hydraulic circuit.
- the fluid handling apparatus 1 transports the fluid between the land facility and the ship, but the objects to be transported are not limited to between the land facility and the tanker.
- the fluid handling apparatus 1 may transport fluid between ships or between a land facility and a vehicle, regardless of the object to which the fluid is transported.
- the ship is not limited to a tanker, and may be a fuel ship that uses fluid as fuel.
