従来のスプリンクラー装置としては、例えば特許文献１に開示されているものがある。この技術は、水道管の途中位置とスプリンクラーヘッドとを消火管で接続し、スプリンクラーヘッドの下流側に流量調整弁を介して水使用器具を取り付け、平時は水道水が流量調整弁を経由して水使用器具側へ給水され、火災時は流量調整弁を閉塞することでスプリンクラーヘッド側へ給水できるようにしたことを特徴とし、水道管内の水道水は絶えず入れ替わるから、水道水の腐敗や消火管の腐蝕・劣化を防止できるというものである。   As a conventional sprinkler device, for example, there is one disclosed in Patent Document 1. In this technology, the midway position of the water pipe is connected to the sprinkler head with a fire extinguishing pipe, and a water-use appliance is attached to the downstream side of the sprinkler head via a flow adjustment valve. During normal times, tap water passes through the flow adjustment valve. Water is supplied to the equipment that uses water, and in the event of a fire, the flow control valve is closed so that water can be supplied to the sprinkler head. Tap water in the water pipe is constantly replaced. It is possible to prevent corrosion and deterioration.

しかしながら、前記の技術は、平時において水道水が消火管を通過する際、水道水の一部が消火管に流れ込み、スプリンクラー装置が作動するまで滞留した状態となるから、水道水の腐敗や消火管の腐蝕・劣化の対策が不十分であった。また、スプリンクラー装置の点検時はスプリンクラーヘッドから散水する水で部屋が水浸しにならないように対策する必要があった。
特開２００５−２１１２８３号公報 However, in the above technology, when tap water passes through the fire extinguishing pipe during normal times, part of the tap water flows into the fire extinguishing pipe and stays until the sprinkler device is activated. Corrosion / deterioration measures were insufficient. Also, when inspecting the sprinkler device, it was necessary to take measures to prevent the room from being flooded with water sprinkled from the sprinkler head.
JP 2005-211283 A

The three-way valve referred to in the present invention has a structure having three ports, or a structure having three or more ports, in which three ports are enabled, or a combination of two valves. The thing of the structure linked so that a valve may be opened and closed relatively is included.

本発明によれば、感知器が部屋の熱又は煙を感知すると電動三方弁の水抜き管側のポートが閉塞されるとともに消火管側の上流及び下流ポートが連通され、水道管の水道水が電動三方弁と手動三方弁を経由してスプリンクラーヘッドまで充水し、部屋の温度が所定温度以上に上昇するとスプリンクラーヘッドがノズルを連通して散水される。   According to the present invention, when the sensor detects room heat or smoke, the port on the drain pipe side of the electric three-way valve is closed and the upstream and downstream ports on the fire extinguishing pipe side are communicated, and the tap water in the water pipe is Water is charged to the sprinkler head via the electric three-way valve and the manual three-way valve, and when the room temperature rises above a predetermined temperature, the sprinkler head is sprinkled with water through the nozzle.

散水が１５〜２０分程の一定時間継続すると消火管側の上流ポートが閉塞されるとともに消火管側の下流ポートと水抜き管側のポートが連通され、水道管からの水道水は電動三方弁で遮水されるとともに、消火管内に残った水道水が電動三方弁と水抜き管を通じて水抜きされ、作動後の消火管内は空となる。このように、非作動時の消火管内は常時空となるから、非作動時における水道水の腐敗や消火管の腐蝕・劣化を確実に防止できる。   When water spraying continues for a certain time of about 15 to 20 minutes, the upstream port on the fire extinguishing pipe side is closed and the downstream port on the fire extinguishing pipe side and the port on the drainage pipe side are connected, and the tap water from the water pipe is an electric three-way valve The tap water remaining in the fire pipe is drained through the electric three-way valve and the drain pipe, and the fire pipe after operation becomes empty. Thus, since the inside of the fire extinguishing pipe when not in operation is always empty, it is possible to reliably prevent the decay of tap water and the corrosion / deterioration of the fire extinguishing pipe when not in operation.

また、スプリンクラー装置の点検時は手動三方弁の消火管側の上流ポートと水抜き管側のポートを連通して消火管側の下流ポートを閉塞しておき、感知器に熱又は煙を感知させると電動三方弁の水抜き管側のポートが閉塞されるとともに消火管側の上流及び下流ポートが連通され、水道管の水道水が電動三方弁を通過するが、手動三方弁で水抜き管へ送水されて水抜きされ、スプリンクラーヘッドには給水されない。   When inspecting the sprinkler device, the upstream port on the fire extinguishing pipe side of the manual three-way valve and the port on the drainage pipe side are connected to block the downstream port on the fire extinguishing pipe side so that the sensor senses heat or smoke. And the drainage pipe side port of the electric three-way valve are closed and the upstream and downstream ports on the fire extinguishing pipe side are connected, and the tap water in the water pipe passes through the electric three-way valve. Water is fed and drained, and no water is supplied to the sprinkler head.

水抜きが一定時間継続すると消火管側の上流ポートが閉塞されるとともに消火管側の下流ポートと水抜き管側のポートが連通され、水道管からの水道水は電動三方弁で遮水されるとともに、電動三方弁と手動三方弁との間の消火管内に残った水道水が水抜き管を通じて水抜きされ、手動三方弁からの水抜きも停止する。点検者は水抜きされた水道水と水抜きの停止を確認することで、機器が正しく作動していることを点検する。このように、実際にスプリンクラーヘッドから散水させることなく容易に点検できる。   When draining continues for a certain period of time, the upstream port on the fire extinguishing pipe side is closed and the downstream port on the fire extinguishing pipe side is connected to the port on the drainage pipe side, and tap water from the water pipe is blocked by an electric three-way valve. At the same time, tap water remaining in the fire extinguishing pipe between the electric three-way valve and the manual three-way valve is drained through the drain pipe, and draining from the manual three-way valve is also stopped. The inspector checks that the equipment is operating correctly by confirming the drained tap water and the stoppage of drainage. Thus, it can be easily inspected without actually sprinkling water from the sprinkler head.

本発明では、制御手段のタイマーの設定時間は二次災害を考慮して１５〜２５分（消防車が火災現場に到着するまでに要する時間）に設定し、タイマーの作動後は火災の状況に係わらず自動的に散水を停止させる。制御手段に前記１５〜２５分間給電できるバッテリーを備えると、停電時でも制御手段及び電動三方弁に給電して作動させることができる。   In the present invention, the setting time of the timer of the control means is set to 15 to 25 minutes (time required for the fire engine to arrive at the fire site) in consideration of the secondary disaster, and after the timer is activated, the situation of the fire is set. Regardless, watering is automatically stopped. If the control means is provided with a battery that can supply power for 15 to 25 minutes, it can be operated by supplying power to the control means and the electric three-way valve even during a power failure.

一般住宅向けにおいては、既存住宅に自動火災報知設備が既に設置されている場合、これを感知器として使用することで、既存の火災受信基盤から火災信号を受けて本発明のスプリンクラー装置を起動させることができ、新たに設備を設ける必要がなく低コストで実施できる。また、木造住宅等で新設する場合は、本発明のスプリンクラー装置を採用することで、住宅用火災警報器を省略できる。本発明の実施例を図面に基づいて具体的に説明する。   For ordinary houses, if an automatic fire alarm system is already installed in an existing house, it can be used as a detector to receive a fire signal from the existing fire receiving base and activate the sprinkler device of the present invention. Therefore, it is not necessary to newly install equipment and can be implemented at low cost. Moreover, when newly installing in a wooden house etc., the fire alarm for houses can be abbreviate | omitted by employ | adopting the sprinkler apparatus of this invention. Embodiments of the present invention will be specifically described with reference to the drawings.
