ている。この緊−急遮断弁１０としては。A pair of pipes 6 and 7 are connected in parallel between the supply pipe 1 and the return pipe 2, and the pipe 6 is connected to an emergency system such as a heat exchanger for removing all residual heat of the diesel power generation equipment. load 8
is interposed. No way, the other pipe line 7 is interposed with a regular system load 9 including an instrument air system load such as an instrument air compressor, and the downstream pipe line 7B of this regular system load 9 is A check valve 11 is interposed. On the other hand, the upstream pipe line 7A of the regular system load 9 has an emergency shutoff valve 1 that is normally open and closed in an emergency.
0 is interposed, and when this emergency shut-off valve 10 is closed, the regular system load 9 including the instrument air system load can be isolated by this emergency shut-off valve 10 and the check valve 11. As this emergency shutoff valve 10.

１３が接続されている。Air-operated valves are used because they can close the valve in a short time and can be applied to large-diameter pipes. According to the air-operated valve, the valve can be closed in about 5 seconds, and can be applied to a pipe 7 having a diameter of about 80 OA. Since the emergency shutoff valve 10 is thus an air-operated valve, the instrument air system 13 is connected to the emergency shutoff valve 10 via the air supply pipe 12.

常用系負荷９の耐震性が非常用系負荷８や熱交換器８、
ポンプ５などと比較して低いため、この部分のみの管路
７の破断による冷却水の漏洩が考えられるからである。The above-mentioned conditions for isolating the regular system load 9 are when a loss of coolant accident occurs, or when cooling water leaks from the equipment, piping, etc. of the regular system load 9, including the instrument air system load, due to an earthquake. be. This means that the earthquake resistance of the regular system load 9, including the 50% air system load, is the emergency system load 8, the heat exchanger 8,
This is because it is lower than that of the pump 5 and the like, so leakage of cooling water due to breakage of the pipe line 7 only in this part is considered.

すくなる機器もある。したがって、誤作動によシ緊急遮
断弁１０が閉じた場合。By the way, if the supply of cooling water to the regular system cargo 9 including the instrument air system loads is stopped, some of the loads 9 will not only lose their functions but also be damaged due to the rise in temperature. There are devices that make it easier. Therefore, if the emergency shutoff valve 10 closes due to malfunction.
全く健全な機器なども使用不能にしてしまうおそれがあ
る。There is a risk that even perfectly healthy equipment may become unusable.
しかしながら、前記緊急遮断弁１０は前述したように計
器用空気を駆動源とする空気作動弁であり。However, as described above, the emergency shutoff valve 10 is an air-operated valve whose driving source is instrument air.

自らの駆動源を失い、開くことができなく浸ってしまう
。すると、計器用空気系負荷を含む常用系負荷の機能回
復を行ガえなくなってしまう。Since this instrument air is supplied from the instrument air system load in the regular system load 9, the emergency shutoff valve 10 loses its own driving source by closing, and is unable to open and becomes immersed. Then, it becomes impossible to recover the functions of the regular system loads including the instrument air system loads.
