Description
【考案の詳細な説明】 本考案はスプリンクラー消火装置への給水を、水道管（１）から直接受けるた めの装置である。DETAILED DESCRIPTION OF THE INVENTION The present invention is a device for directly receiving water supply to a sprinkler fire extinguisher from a water pipe (1).
従来の我が国におけるスプリンクラー消火装置は水質保全の目的から消火装置 用配管内の水が水道及び生活用給水管に逆流しないよう、一たん受水槽に溜めた 水をポンプで加圧送水することが一般化しているが、最近の水道事業は送水設備 の管理が向上し、全般に著しい水圧低下や断水の機会がほとんど無くなったこと から、生活用水の衛生を保ち、且つ水道から直接供給された水を初期消火に利用 する方法の開発が喫緊の課題となっており中でも、住宅用防災機器の開発による 「住宅防火」は消防庁が国家的事業に取りあげるところとなった。 In the conventional sprinkler fire extinguisher in Japan, for the purpose of water quality conservation, it is common to pump the water stored in the receiving tank with a pump to prevent the water in the fire extinguisher piping from flowing back to the water supply and domestic water supply pipes. However, in recent water supply business, the management of water supply facilities has improved, and there has been almost no significant decrease in water pressure or almost no interruption of water supply.Therefore, sanitation of domestic water is maintained and water supplied directly from water supply is used. Even though the development of methods for use in initial fire extinguishing has become an urgent issue, the “Housing Fire Prevention” by developing housing disaster prevention equipment has been taken up by the Fire Department as a national project.
このため、本考案は三方電動弁（４）により、平素は生活用水に供給されてい る水道水を、火災発生時のみスプリンクラー消火装置用水に切り換える装置であ る。しかも、この装置の使用によって生活用水に汚濁が生じたり、不衛生になる 恐れの全くない装置である。 Therefore, the present invention is a device for switching the tap water, which is normally supplied to domestic water, to the water for the sprinkler fire extinguisher only by a three-way motorized valve (4) when a fire occurs. Moreover, there is no risk of pollution of household water or unsanitary use of this device.
本装置の構造を図により説明する。 The structure of this device will be described with reference to the drawings.
水道管（１）から供給された水は、平素、生活用給水管（５）に流れるよう三 方電動弁（４）を設定し、もし火災が発生すれば、加圧されていた消火用送水管 （８）内の圧力が大気圧まで低下したことを圧力スイッチ（６）が感受し、三方 電動弁（４）を切り換えて生活用給水を遮断すると同時に、消火用送水管（８） には当該配管による 給水能力最大の水量が流れる よう事前に設定する。 Set the three-way motorized valve (4) so that the water supplied from the water pipe (1) normally flows to the domestic water supply pipe (5). If a fire occurs, the pressurized fire extinguishing water is sent. The pressure switch (6) senses that the pressure in the water pipe (8) has dropped to atmospheric pressure, and switches the three-way motorized valve (4) to shut off the water supply for daily use, and at the same time, the water supply pipe (8) for extinguishing fire It is set in advance so that the maximum water supply capacity through the relevant pipes flows.
また、消火用送水管（８）内には平素は水がなく、加圧された空気が充満され ている。その加圧方法は消火用送水管（８）の末端仕切弁（１１）を閉じ、三方 電動弁（４）の二次側に設けられた消火用送水管（８）へ高圧空気を注入するた めの空気管接手雌（１２）と高圧空気ボンベ（１６）と連結している空気管接手 雄（１３）を結合させ、閉鎖型スプリンクラーヘッドから空気が漏れない程度の 適宜圧力の空気を消火用送水管（８）に注入する。 The fire extinguishing water pipe (8) is normally free of water and filled with pressurized air. The pressurizing method was to close the end sluice valve (11) of the fire extinguishing water pipe (8) and inject high-pressure air into the fire extinguishing water pipe (8) provided on the secondary side of the three-way motorized valve (4). For extinguishing air at an appropriate pressure so that air does not leak from the closed type sprinkler head by connecting the female air pipe joint (12) for connection with the male air pipe joint (13) connected to the high pressure air cylinder (16). Inject into the water pipe (8).
この際、加圧する空気圧力は高圧空気ボンベ（１６）の頭部に取りつけられた 圧力調整弁（１４）で調整し、加圧後は空気管用仕切弁（１７）を閉じるか、空 気管接手雌（１２）に自動閉鎖装置付き接手を 使用することにより空気管接手 の雄（１３）と雌（１２）の結合は取りはずしてもさしつかえない。また、その 後の消火用送水管（８）内の圧力は当該配管末端の圧力計（１０）で観測し、維 持管理することができる。 At this time, the air pressure to be applied is adjusted by the pressure adjusting valve (14) attached to the head of the high-pressure air cylinder (16), and after pressurizing, the air pipe sluice valve (17) is closed or the air pipe connecting female is closed. By using a joint with an automatic closing device for (12), it is possible to remove the connection between the male (13) and female (12) of the air pipe joint. Further, the pressure in the fire extinguishing water supply pipe (8) after that can be maintained and controlled by observing it with the pressure gauge (10) at the end of the pipe.
火災の熱により閉鎖型スプリンクラーヘッド（９）が作動、開放すれば消火用 送水管（８）内の圧力は大気圧と同等まで低下し、これを消火用送水管（８）に 設けられた圧力スイッチ（６）が感受し、三方電動弁（４）を作動させて生活用 給水管（５）への給水を遮断し消火用送水管（８）への送水が開始され、放水す る。 When the closed type sprinkler head (9) is activated and opened by the heat of fire, the pressure in the fire extinguishing water pipe (8) drops to the same level as atmospheric pressure, and this pressure is set in the fire extinguishing water pipe (8). When the switch (6) senses it, the three-way motorized valve (4) is activated to shut off the water supply to the domestic water supply pipe (5) and start the water supply to the fire extinguishing water supply pipe (8) to discharge it.
なお、三方電動弁（４）は必ず手動操作が可能な電動・手動兼用型を採用する ことにより、水路の事前設定および保守管理が容易にできるものである In addition, the three-way motorized valve (4) can be easily operated by manual operation so that the waterway can be preset and maintained easily.
