れる。FIG. 3 is a cross-sectional view showing an example of a pressure vessel used in the test specified by the Fire Service Law. The container body 1 has a cylindrical shape made of stainless steel and has an internal volume of 200 cm 3 . An attachment pipe 2 is connected and communicated above the side peripheral surface, and an orifice plate 3 having a prescribed thickness having a prescribed pore is fixed to the opening end thereof by a fixing member 4 via a heat resistant gasket. ing. Further, as shown in an enlarged manner in FIG. 4, a ridge 5 is circumferentially formed along the end face at the open upper end of the container body 1. Then, a circular rupture plate 6 is set on the container body 1, and the ridge 5
A fixing ring 8 having a circumferential groove 7 that fits in is fitted from above, and the fixing ring 8 and the container body 1 are fixed by a fixing screw 9 provided on the container body 1. As a result, the peripheral portion of the rupturable plate 6 is deformed into a shape along the recessed groove 7 and the protrusion 5 that are fitted to each other, and is clamped and fixed.
試験に際しては、前記の圧力容器を加熱器にかけ、あら
かじめ容器本体１内に収納しておいた試料を加熱する。
試料が加熱分解すると、静圧はオリフィス板３の細孔か
ら逃げるが、急激に上昇する爆発圧力が破裂板６に加わ
り、該破裂板６を破裂させる。In the test, the above-mentioned pressure vessel is put in a heater to heat the sample stored in the vessel body 1 in advance.
When the sample is decomposed by heating, static pressure escapes from the pores of the orifice plate 3, but a rapidly rising explosion pressure is applied to the rupture plate 6 and ruptures the rupture plate 6.
一般に、前述した危険物の確認試験においては、試料の
加熱分解による昇圧速度は非常に速い。このため、破裂

さらに上昇することから、計測上は破裂圧力範囲が設定
よりも高くなってしまう。このような状態では、いかに
高い品質に管理された材料であっても、破裂板として使
用することはできなくなってしまう。Generally, in the above-mentioned confirmation test of dangerous substances, the rate of pressurization due to thermal decomposition of the sample is very high. For this reason, the rupture disc receives the explosion pressure before it ruptures and is pulled upwards,
The part that is sandwiched between the container body and the fixing ring slides inward. If the stress state of the rupture disc changes due to slippage, the strength of the material changes and the rupture pressure of the rupture disc is affected, and the pressure rises further during the delayed rupture, so the rupture pressure range is measured. It will be higher than the setting. In such a state, no matter how high the quality of the material is controlled, it cannot be used as a rupturable disc.
このような破裂板の固定部分におけるすべりを防止する
ため、前述のように従来は凹溝７と突条５の嵌合によっ

圧力が設定範囲から変動してしまうという問題があっ
た。In order to prevent such slippage in the fixed portion of the rupture plate, as described above, conventionally, the peripheral edge portion of the rupture plate 6 was deformed and held by fitting the concave groove 7 and the protrusion 5, as described above. With such a fixed structure, even if slip can be prevented, the burst pressure itself causes unnecessary and unpredictable stress and work hardening, so the burst pressure still fluctuates from the set range. was there.
また、このような凹溝７と突条５の嵌合による破裂板６
の固定構造によれば、シール性が低いという問題点もあ
った。In addition, the rupture plate 6 due to the fitting of the groove 7 and the protrusion 5 as described above.
According to the fixing structure of No. 1, there is a problem that the sealing property is low.

消防法に定める危険物確認試験は、いくつかの条件下で
複数回試験を繰返した結果から評価を行う方法なので試
験回数が非常に多く、上述したように容器本体１を再加
工しなければならないような構造は好ましくない。Further, in the fixing structure, since the ridge 5 is directly processed on the upper end portion of the container body 1 and the rupture plate is sandwiched between the ridge 5 and the concave groove 7 with a strong force, the ridge 5 may be formed while the test is repeated. It may be deformed, and in that case, there is a problem that the container body 1 has to be reworked. In particular, the dangerous goods confirmation test specified in the Fire Service Law mentioned above is a method in which the evaluation is performed from the result of repeating the test multiple times under some conditions, so the number of tests is very large, and as described above, the container body 1 is reprocessed. Structures that must be done are not preferred.

って規定される。The peripheral edge of the rupture plate is clamped between the flat lower surface of the fixing ring and the clamping surface of the retaining ring, and is fixed to the upper end of the container body. Since the retaining ring contacts the rupturable plate only on the sandwiching surface of the circumferential convex portion, the sandwiching pressure is uniform and large, and a high sealing property is obtained without generating unnecessary stress.
Further, even if the explosion pressure generated in the container body at the time of the test is applied to the rupture plate, there is no possibility that the rupture plate slips inward because the corners of the sandwiching surface are pushed into the peripheral edge of the rupture plate. Further, the burst pressure range of the flat plate-shaped burst plate is defined by the inner diameter of the fixing ring.

へすべる恐れはない。Then, the container body 10 is set on the electric furnace, and the sample stored in advance in the container body 10 is heated to perform the test. When the sample is decomposed by heating, static pressure escapes from the pores of the orifice plate 3, but explosive pressure is applied to the rupturable plate 15. When such an explosion pressure acts, the rupture plate 15
Although slippage at the peripheral edge portion 15a becomes a problem, in the present embodiment, even if the explosion pressure generated in the container body 10 is applied to the rupturable plate 15, the corner portions 17 and 18 of the holding surface 16 cause the peripheral edge portion of the rupturable plate 15 to become. There is no fear that the rupturable plate 15 will slide inward because it is difficult to insert 15a.
