Description

Detailed Description of the Invention (Industrial Application Field) This invention mainly relates to a pressure vessel for ultra-high pressure or high pressure, in which a communication passageway used for wiring or fluid circulation to the inside of the vessel is formed. Regarding containers.

(Prior art) As a means for attaching the lid member to the body of the container in a pressure container for ultra-high pressure or high pressure,
As described in Japanese Patent No. 48-79315, annular joints that can be fitted to each other are formed at the opening end of the body and the edge of the lid member, and the joints are connected using a number of fastening pins that are inserted into both annular joints in the radial direction. (finger)
A pin closure type) has been proposed.

When a large number of fastening pins are used in a joint, such as in this type of pressure vessel, pin holes into which the fastening pins are inserted are formed in the joint. A reinforced structure is adopted.

When forming a wiring hole for drawing out the conductor wire of a heater or thermocouple fixed inside the container to the outside of the container, or a fluid passage into the inside of the container, the above-mentioned joint part is used. To avoid this, a through hole separately provided in the container body or lid member is used, but in general, it is necessary to reinforce this through hole in a pressure vessel.

(Problems to be Solved by the Invention) When a through hole is separately provided in the container body or lid member, avoiding the joint portion into which the fastening pin is inserted as described above, the reinforcement of this through hole portion must be done at the time of manufacture. In this case, it is necessary to either predict the opening of the through hole and make the area thicker in advance, or to strengthen the area near the through hole after the through hole is drilled, but both of these methods reduce the manufacturing cost. Not only does this result in a steep increase in the price of the holes, but there may also be restrictions on the size, location, number, etc. of the through holes.

In addition, when introducing conductive wires, piping, etc. from the lid member, special structures such as providing a connector to attach and detach them when opening and closing the lid member, or a double lid structure to avoid attachment and detachment are required. need to be adopted.

The present invention has been made in view of the above points, and the present invention skillfully utilizes the joint between the container body and the lid member to form a communication passage inside and outside the container, and in forming the communication passage. It is an object of the present invention to provide a pressure vessel that does not require consideration of reinforcement, has high flexibility in forming communication passages, and is extremely advantageous in terms of manufacturing cost.

(Means for Solving the Problems) The basic structure of the present invention for achieving the above object is to apply pressure using a fastening pin to connect the bodies of divided containers or to connect the bodies and the lid member. The pressure vessel is characterized in that a communication passage between the inside and outside of the container is formed by penetrating the fastening pin.

(Embodiment) FIGS. 1a, b, and c are sectional views of a joint portion according to an embodiment of the present invention.

In the figures, an example will be described in which the body and the lid member are connected, but the joint portion that connects the divided bodies is also similar.

In the figure, 1 is the body of the container, 2 is the lid member, and 3
is a joint portion between the body 1 and the lid member 2.

The body side joint part forms an annular fitting groove 3a and consists of concentric inner and outer cylindrical joint walls 3b, 3c, and the lid member side joint part forms a cylindrical fitting groove 3a that fits into the annular fitting groove 3a on the body 1 side. It forms a joint edge 3d.

4 is a fastening pin used in the joint part 3 for the purpose of attaching the lid member 2 to the body 1, and has a through hole 5 inside the body, and the lid member 2 is inserted into the annular fitting groove 3a on the body 1 side.
With the side cylindrical joint edge 3d fitted, it is inserted into the pin hole 6 commonly provided in the joint part 3.

In the figure, 7 is a sealing member, and 8 is an O-ring disposed at the tip of the fastening pin 4.

In the first embodiment shown in FIG. The penetrating portion is provided with a small diameter portion 6a corresponding to the through hole 5 of the fastening pin 4. In the illustrated example, the conductor 9 to be connected to external equipment is inserted through the through hole 5 of the fastening pin 4 via an insulator, and the terminal member 10 to be connected to the equipment inside the container is sealed in the small diameter hole 6a on the side of the body 1. The conductor 9 and the terminal member 10 are connected to each other by inserting the fastening pin 4 into the pin hole 6.
are configured to be electrically connected.

In the second embodiment shown in FIG. It is used as a part of the container to allow fluid to flow inside and outside the container.

In the third embodiment shown in Figure c, a fastening pin 4 is inserted through the inner and outer cylindrical joint walls 3b and 3c of the body 1, and the through hole 5 of the fastening pin 4 is used for fluid circulation inside and outside the container. This embodiment is similar to the second embodiment, but this embodiment employs a structure in which the end of the internal pipe 11 in the container is aligned with the fastening pin 4 and fixed to the inner wall surface of the body.

Figure 2 shows this invention as a HIP (Hot Isostatic)
FIG. 2 is a sectional view of a joint part applied to a container (Press).

In this embodiment, the lid member 2 is provided with a solid insert 12 that is inserted into the body of the container to a suitable depth, and an annular heater support ring 13 is interposed between the insert 12 and the inner wall of the body. By installing the seal member 7 between the insert body 12 and the support ring 13 and between the support ring 13 and the body 1, and moving the seal member 7 away from the joint part and toward the inside of the body. It is configured to reduce the circumferential stress due to the pressure inside the container that acts on the joint, and when the conducting wire 14 of the thermocouple installed inside the container is pulled out to the outside of the container, the conducting wire 14 is connected to the heater support ring 13. The support ring 13 is passed through the support ring 13 in the axial direction.
is connected to the contact plate 14a in the hollow part 15 provided between the insert body 12 and the one fastening pin 4 of the joint part 3.
The conductor 9 to be connected to external equipment is inserted and held in the through hole 5 of the fastening pin 4 via the insulator in the same manner as in the first embodiment, and the contact 9a provided at the end of the conductor 9 is Hollow part 1 from small diameter hole 6a on fuselage 1 side
5 and by pressing the tip of the contact plate 14a against the contact 9a, the conductor 9
and the thermocouple conducting wire 14 are electrically connected.

Further, when the other fastening pin 4 of the joint portion 3 is used, the through hole 5 of the fastening pin 4 and the fluid passage 16 provided in the insert body 12 are communicated with each other as in the second embodiment. This allows fluid to flow inside and outside the container.

(Effects) As explained above, the present invention has the following effects because the fastening pin is passed through to form a communication passage between the inside and outside of the container.

(1) Conductive wires installed in the body and lid of the pressure vessel,
In addition, all or some of the through holes for piping can be omitted, simplifying the structure of the container.

(2) When the lid member is opened and closed, the conductor wires and piping connections drawn from the inside of the container to the outside are automatically attached and detached, which is effective in simplifying operation and preventing erroneous operation. There is no need to adopt a special structure, and manufacturing costs can be reduced.

(3) Even if the container is subjected to ultra-high pressure and becomes larger and the lid member becomes extremely thick, it becomes easy to draw out the conductor wires and piping to the outside of the container.
