Claims (1)
とし、供給側にタンクを設け、このタンク内は常に圧力
の上限と下限とを有し、タンクに導入する水は、ポンプ
より、空気層、逆止弁を通り、タンク内の圧力により、
ポンプが回転すると弁は開き、停止すると閉じる逆止弁
を弾性体とし、圧力上昇時は高圧で弁を閉とし、下降時
は圧力を低い所で開とする逆止弁。When supplying water, the pump is rotated as necessary, a tank is provided on the supply side, and this tank always has an upper and lower pressure limit, and the water introduced into the tank is controlled by the pump. Through the air layer and check valve, due to the pressure inside the tank,
This check valve uses an elastic body to open the valve when the pump rotates and closes when the pump stops.When the pressure increases, the valve closes at high pressure, and when the pump decreases, it opens at low pressure.
