Connecting pipe 15 → Connection 23 → Chamber 26 → Connection 24 → Connecting pipe 16 → Water supply pipe 13 → Connection port 38 → Expansion pipe 33 → Connection 3
7 → Becomes the suction side of the circulation pump 4.
又第２の弁体２８が少し押し下げられ接続口２３０通路
が開かれると、今まで第２の弁体２８のみに働いていた
圧力は面積の大きい第２のダイヤフラム２５にも力弓る
ため第２のダイヤフラム２５は大きく押し下げられる。Also, when the second valve body 28 is pushed down a little to open the connection port 230 passage, the pressure that has been acting only on the second valve body 28 is also applied to the second diaphragm 25, which has a large area, so that the pressure is The second diaphragm 25 is pushed down significantly.

ｌ以下になると、スプリング２９の力により第２の弁体
２８を押し上げ、接続口２３０通路が閉じる。While the above-mentioned circulation continues, the pressure inside the system decreases due to water leakage, etc., and the suction side pressure of the circulation pump 4 decreases to 0.5 kg/cn.
When it becomes less than l, the force of the spring 29 pushes up the second valve body 28, and the connection port 230 passage closes.
そのため、前記の循環系路ａが停止される。Therefore, the circulation path a is stopped.
第１のダイヤフラム２２に連結された第１の弁体３５は
循環用ポンプ４の吐出圧のために押し上げられ、ノズル
３２の入口通路は開の状態になる。The first valve body 35 connected to the first diaphragm 22 is pushed up by the discharge pressure of the circulation pump 4, and the inlet passage of the nozzle 32 is opened.

のを防止できるようになっている。The suction side pressure of the circulation pump 4 is o, 8 kg/cAI
When tc is reached, the second valve body 28 is pushed down again as described above, and the circulation path a is restored. At the same time, the passage of the nozzle 32 of the jet pump 34 is closed by the first valve body 35, and the circulation system path a is closed. is closed, the suction pressurizing action of the jet pump 35 is stopped, and the system internal pressure can be prevented from increasing excessively.
