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) Japanese Patent Application Laid-Open No. 48-7931 discloses a means for attaching a lid member to the body of a pressure vessel for ultra-high pressure or high pressure.
As described in Publication No. 5, an annular joint that can be fitted to each other is formed at the opening end of the body and the edge of the lid member, and the joints are connected using a large number of fastening pins that are inserted in the radial direction into both the toilet joints. A structure (finger 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 pulling out the conductor wires of a heater or thermocouple fixed inside the container to the outside of the container, or a fluid passageway into the container, avoid the above-mentioned joints and insert the container into the container. Although a through hole separately provided in the body or lid member is used, it is generally 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 anticipate the drilling of the through-hole and make the area thicker in advance, or to perform reinforcement work near the through-hole after the through-hole is drilled.
In either case, not only does the production cost rise, but the size, position, number, etc. of the through holes may be limited.

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.

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

(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, 1B, and 1C are cross-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 the body 1
and a joint portion of the lid member 2.

The body side joint part is formed of an annular fitting groove 3a and consists of concentric inner and outer cylindrical joint walls 3b, 3c, and the lid member side joint part is
Cylindrical joint edge 3d that fits into the annular fitting groove 38 on the body 1 side
is formed.

4 is a joint part 3 for the purpose of attaching the lid member 2 to the body 1.
It is a fastening pin used in the body, has a through hole 5 in the body, and has a cylindrical joint edge 3d of two lid members in the annular fitting groove 38 on the body 1 side.
When the pin holes 6 commonly provided in the joint part 3 are fitted together,
is inserted into the

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. A small diameter hole 6 corresponding to the through hole 5 of the fastening pin 4 is provided in the non-penetrating part.
This is a configuration in which a is provided. 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 configured to be electrically connected by inserting the fastening pin 4 into the pin hole 6.

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

In the third embodiment shown in Figure (C), a fastening pin 4 is inserted and penetrated through the inner and outer cylindrical joint walls 3b and 3c of the body l, and the through hole 5 of the fastening pin 4 is used for fluid circulation inside and outside the container. Although it is similar to the second embodiment in terms of use, 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 HI P (Hot l5osta).
ticPress) is a sectional view of a joint part applied to a container.

In this embodiment, the lid member 2 is provided with a solid insert 12 which is inserted to a suitable depth inside the body of the container;
An annular heater support ring 13 is interposed between the insert body 12 and the inner wall of the body, and a seal member 7 is installed between the insert body 12 and the support ring 13 and between the support ring 13 and the body 1. The structure is such that the circumferential stress caused by the pressure inside the container that acts on the joint is reduced by moving the position away from the joint and closer to the inside of the body. To draw out the conductive wire 14 to the outside, the conductive wire 14 is passed through the heater support ring 13 in the axial direction and connected to the contact plate 14a in the hollow part 15 provided between the support ring 13 and the insert body 12. Using two fastening pins 4, a conductor 9 to be connected to external equipment is inserted and held through the through hole 5 of the fastening pin 4 via an insulator in the same manner as in the first embodiment. The conductor 9 and the thermocouple conductor wire 14 are electrically connected by making the contact 9a protrude into the hollow part 15 from the small diameter hole 6a on the side of the body 1, and pressing the tip of the contact plate 14a against the contact 9a. I try to do that.

Furthermore, if the other fastening pin 4 of the joint part 3 is used, the through hole 5 of the fastening pin 4 and the insert body 1 can be connected similarly to the second embodiment.
A fluid passage 16 provided in the container 2 is communicated with the container 2 to allow 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 member 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;
Moreover, there is no need to adopt a special structure such as a double lid structure,
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.
