Description
詳述すれば、例えば、現時点で現在水位Lbの状態から、揚水ポンプが作動して揚水ないし配水が行われると、水位は高水位給水開始位置Lcに至り、この時点で水位センサ24の出力に応じて制御部18により給水弁16が開放して給水が行われる。この給水量が配水を上回れば、その後、高水位給水停止位置Laが検知されて、給水が停止する。したがって、貯水槽10内の水位は、消費容量に対応して制御部18を高水位に設定しておけば、通常、高水位給水停止位置Laと高水位給水開始位置Lcとの間に維持される。
また、凍結防止用の通水を、一定量連続して実行するか、時間的に断続的に実行するかは、その凍結防止効果の程度によって、さらには貯水槽の安全限度内の貯水容量によって、いずれをも選択することができるが、いずれでも可能である。
Claims (4)
- 給水バルブを経由して給水し、貯水槽に所定量の水を貯溜するとともに、この貯水槽から配水するようにした水位制御部を有する給水システムにおいて、前記給水バルブの外表面に温度センサを設け、この温度センサが前記給水バルブの凍結可能外気温度を検知するとスタートし、給水バルブが凍結する可能性がある給水停止時間経過以前に前記給水バルブを制御して、所定時間、凍結防止用の給水をするタイマを設けたことを特徴とする給水システム。
- 前記凍結防止用の給水量は、前記タイマが作動する時点の水位から、前記貯水槽の溢水水位までの範囲内で設定されることを特徴とする請求項1記載の給水システム。
- 前記温度センサの温度出力は、約−5℃であり、凍結防止用の給水は、その出力から約1時間以内であることを特徴とする請求項1、2のいずれか1項記載の給水システム。
- 前記タイマは、所定時間の通水後その制御を所定回数繰返すことを特徴とする請求項1−3のいずれか1項記載の給水システム。
