性体コアにしてこねに電磁石５４を設けても良い。The magnetic field applying means 5 includes a gap 2 of the pressure control section 2.
This is a device that generates a magnetic field at 1, usually as shown in Figure 1.
A pair of permanent magnets 51.52% may be made to face each other with a gap 21 in between, or alternatively, an annular magnet 53 as shown in FIG. 3 may be used, but in some cases, the magnet 53 shown in FIG. An electromagnet 54 may be provided in the kneading device.

と圧力放散部３とは磁性流体６によって連断されており
、磁性流体６はギャップ２１に作用する磁界の強さによ
って所定の遮断力を有しつつギャップ２１を盲塞してい
る。Since the device of the present invention is as described above, normally the pressure receiving part 1
and the pressure dissipation section 3 are connected to each other by a magnetic fluid 6, and the magnetic fluid 6 blindly blocks the gap 21 while having a predetermined blocking force depending on the strength of the magnetic field acting on the gap 21.
この状態で、今、圧力容器７からの流体圧力が増大し、
その圧力が上記磁性流体６の有する遮断力を超えたとす

タ３２８通って外気中に放散される。In this state, the fluid pressure from the pressure vessel 7 is now increasing,
If the pressure exceeds the blocking force of the magnetic fluid 6, this pressure causes the magnetic fluid 6 to scatter as shown by the chain line in FIG. 1, thereby opening the gap 21. It passes through the filter 328 from the diffusion chamber 31 and is diffused into the outside air.

状に復元される事になる。When the pressure in the pressure vessel 7 attenuates and returns to normal, the magnetic fluid 6
is returned to the gap 21 and fixed again between the gear knobs 21, so that the safety valve device cover is automatically restored to its original state.

しめ得る利点がある。The return of the magnetic fluid 6 to the gap 21 is performed by the gap 2
If the inner wall surface of the pressure dissipation chamber 31 is inclined toward the gap 21 as in the embodiment, the scattered magnetic fluid 6 will flow downward toward the gap 21. , there is an advantage that the return of the magnetic fluid 6 can be ensured.
