TECHNICAL FIELD The present invention relates to a pressure-resistant container that is subjected to external pressure, and more particularly to a pressure-resistant container that has improved joints. Conventionally, as a pressure container with a joint, the first
(broken side view) and FIG. 2 (enlarged sectional view of the flange part), the flange part 1a of the cylindrical part 1 and the flange part 2a of the hemispherical part 2 are
They are connected by a large number of bolts 4 and nuts 5. Further, the hemispherical portion 3 also has a flange portion 3a.
is connected to the flange portion 1b of the cylindrical portion 1 by bolts 6 and nuts 7, similarly to the hemispherical portion 2 described above. Then, as shown in FIG. 2, the flange portion 1
a, 2a have bolt holes 1a' for bolts 4,
2a' is formed, as well as O as a sealing material.
A ring 8a is provided. In addition, the flange parts 1b and 3a are also comprised similarly to the above-mentioned flange parts 1a and 2a. By the way, when such a pressure vessel is installed in a manned or unmanned diving vessel at great depths, since the flanges 1a, 1b, 2a, and 3a protrude,
Not only does it require a space larger than the flange diameter, but also these flanges and a large number of bolts 4,
There is a problem in that the added weight of the nuts 5 and 7 cannot be ignored for deep diving hulls, where lightweight and compact design is the most important consideration. Another problem is that when maintaining and inspecting equipment stored in pressure vessels, it is necessary to install and remove a large number of bolts 4, 6 and nuts 5, 7 in order to open and close the pressure vessel. . The present invention attempts to solve these problems.Instead of the joint structure in which bolts are inserted through the flanges and tightened with nuts, in prefabricated pressure-resistant containers that receive external pressure, a close-fitting joint structure is used. An object of the present invention is to provide a pressure-resistant container that is made smaller and lighter, and that maintains sealing performance by increasing the pressure-resistant strength at the joint. Therefore, the pressure-resistant container of the present invention is a pressure-resistant container that is composed of a cylindrical part and a hemispherical part connected to both ends of the cylindrical part through removable annular joints, and can withstand high pressure from the outside. Concave and convex portions are formed on one and the other of the opposing ends of the annular joint, and an engagement is formed in the concave and convex portions along the circumferential direction so as to fit tightly into each other to maintain the initial tightening pressure. a surface and a radially opposing surface with a sealing material interposed therebetween,
The outer circumferential surface of the annular joint part is formed flush, and the protruding direction of the convex part in the uneven part is set in the same direction as the tightening direction of the sealing material for both the cylindrical part and the hemispherical part. It is characterized by being Hereinafter, a pressure-resistant container as an embodiment of the present invention will be explained with reference to the drawings. FIG. 3 is a partially cutaway side view of the container, and FIG. 4 is a cross-sectional view showing an enlarged portion of FIG. 3. , FIG. 5 is an enlarged cross-sectional view of the same portion shown in FIG. 3 in an open state, and FIG. 6 is an enlarged cross-sectional view showing a state in which a hemispherical attachment/detachment jig is attached to the hemispherical portion. As shown in FIGS. 3 to 6, a cylindrical portion 11 and hemispherical portions 12 each connected to both ends of the cylindrical portion 11,
In a three-part pressure container 10 (a container that can withstand high pressure from the outside) consisting of 13, detachable annular joints 16, 16 are provided, and these engaging parts 16 connect the cylindrical parts 11 facing each other. Concave and convex portions are formed on one end and the other of the hemispherical portions 12 and 13, respectively, and these concave and convex portions engage with each other, so that the outer circumferential surface of each annular joint portion 16 is flush. It is formed. In these uneven portions, as shown in FIG.
1a, 12a, and an opposing surface 11 along the radial direction with an O-ring 15 interposed therebetween as a sealing material.
b, 12b are formed, and the projecting direction of the convex parts A, B in the uneven part is set in the same direction as the tightening direction of the O-ring 15 for both the cylindrical part 11 and the hemispherical parts 12, 13. has been done. Note that in order to mount the O-ring 15, an O-ring groove 14 is provided on one opposing surface 11b. Further, the hemispherical parts 12 and 13 are provided with mounting seats 22 and 23 into which the working end of the hemispherical part attachment/detachment jig 21 can be screwed.
is provided. In addition, the reference numeral 24 in FIGS. 3 to 6 indicates a fixing base, P indicates the external pressure, P O indicates the pressure inside the pressure container, and Q indicates the driving direction of the jig 21. The above-described pressure-resistant container 10 receiving external pressure of the present invention has the following features:
At the annular joint 16, the hemispherical parts 12, 13
An engaging surface 12a along the circumferential direction in the uneven portion of the cylindrical portion 11 and an engaging surface 1 along the circumferential direction in the uneven portion of the cylindrical portion 11.
1a, each annular joint part 1
6 is in a closed state, and the fitting force of the engaging surfaces 11a, 12a along the circumferential direction is applied to the O-ring 15.
By making the repulsive force larger than the
That is, by maintaining the initial tightening pressure on the engaging surfaces 11a and 12a, the closed state of the joint 16 is maintained even when no external pressure is applied to the pressure vessel 10, and the sealing performance of the O-ring 15 is maintained. I can do it. In addition, the internal pressure of the pressure vessel 10 is maintained at atmospheric pressure P 0 , and the external pressure P such as high water pressure in the deep sea is applied to the outer surface of the vessel 10.
is applied, the external pressure causes each joint 1
The uneven parts 6 are now firmly engaged with each other, and the O-ring 15 is sufficiently compressed.
The internal pressure P 0 of the pressure vessel 10 is safely maintained. Since the projecting direction of the convex portions A and B of the concavo-convex portion of each joint portion 16 is set in the tightening direction of the O-ring 15 for both the cylindrical portion 11 and the hemispherical portions 12 and 13, these convex portions Part A,
There is no possibility that a large bending moment due to external pressure will be applied to B and the sealing performance of the O-ring 15 will be impaired. Note that the fitting force at the engaging surfaces 11a, 12a along the circumferential direction can be determined in advance according to the relationship shown in the following table, corresponding to the hardness of the O-ring 15 and the inner diameter of the O-ring 15.

Once attached, the hemispherical portion 12,
13 can be easily attached and detached. In addition,
The jig 21 is also used to hold down the hemispherical parts 12 and 13 during the internal pressure airtightness test of the pressure vessel 10. As described above, in this flangeless external pressure pressure vessel 10, the annular joint portion 16 is provided with an uneven portion, and the engaging surfaces 11a and 12a along the circumferential direction of the joint portion 16 are tightly fitted. Due to the fitting force, the annular joint 16
The closed state of the O-ring 15 is maintained, and since the convex portions A and B of the uneven portion are set in the tightening direction of the O-ring 15 for both the cylindrical portion 11 and the hemispherical portions 12 and 13, the O-ring 15 is sufficiently maintained without impairing the sealing performance, and the maximum outer diameter of the pressure vessel 10 is smaller than that of a conventional flanged bolt and nut tightening structure. Since the outer circumferential surface is formed flush with no steps, the maximum outer diameter of the pressure vessel 10 can be further reduced, and there is an advantage that the equipment space in a submersible hull or the like can be significantly reduced. In addition, by omitting flanges, bolts, nuts, etc. of the pressure vessel 10, the weight of the pressure vessel 10 is reduced, and in addition to reducing the amount of buoyancy material required to compensate for this weight, this also reduces the size and weight of the submersible hull. It is possible to make changes. As detailed above, the pressure container of the present invention is composed of a cylindrical part and a hemispherical part connected to both ends of the cylindrical part through removable annular joints, so that it can withstand high pressure from the outside. In a pressure vessel,
Concave and convex portions are formed on one and the other of the opposing ends of the annular joint of the container, and the concave and convex portions are formed along the circumferential direction so as to fit tightly into each other to maintain the initial tightening pressure. an engaging surface and a radially opposing surface having a sealing material interposed between them, so that the outer circumferential surface of the annular joint portion is flush with the surface, and the convex portion of the concave and convex portion is formed. It has a simple structure in which the protrusion direction of both the cylindrical part and the hemispherical part is set in the same direction as the tightening direction of the sealing material. (Reduction of maximum outer diameter)
It also has the advantage of being lightweight (omission of flanges, bolts, etc.), and of maintaining appropriate pressure resistance at the joint between the cylindrical part and the hemispherical part, thereby maintaining the sealing performance of the sealing material.
