【０００１】0001
本考案は寒冷地で使用される地上用の消火装置に関する。 The present invention relates to a ground fire extinguishing system used in cold regions.
【０００２】0002
従来寒冷地で使用されていた消火栓は、地中に埋設された弁箱と地上の放水部 本体をパイプで接続し、弁箱内の弁体をロッドで延長して放水部本体近傍にもう けるハンドルで開閉および排水の操作をしていた。 Fire hydrants traditionally used in cold regions consist of a valve box buried underground and a water discharge section above ground. Connect the main body with a pipe, extend the valve body inside the valve box with a rod, and install another one near the water discharge part main body. The handle was used to open, close, and drain water.
【０００３】 しかし、消火栓は戸外に設置されることと、操作部が水の流路と接しているた め、厳寒期などは例え水抜き操作をしても操作部分で残留水滴が凍結し、次に水 を出すときにハンドルが回らず、湯をかけて氷を溶かしてから操作しなければな らないので、それだけ消火作業が遅れるという欠陥があつた。さらに従来のもの は、ねじによりハンドルを何回も回転させないと全開にならないため、やはりそ の分だけ消火作業に影響を受けるという欠陥もあった。0003 However, because fire hydrants are installed outdoors and the operating part is in contact with the water flow path, Therefore, during extremely cold seasons, even if you drain the water, residual water droplets will freeze on the operating part, and the next The handle won't turn when you try to take it out, so you have to pour hot water on it to melt the ice before you can operate it. The problem was that the fire extinguishing work was delayed due to the lack of equipment. Even more conventional The handle cannot be fully opened unless the screw handle is rotated many times, so There was also a flaw in that it affected the fire extinguishing work by the same amount.
【０００４】0004
そのため、迅速に開閉作業ができ、しかも厳寒期においても凍結せず、すぐに 水の出るもので、さらに当然のこととして長期間安定して使用できる消火装置を いかにして提供せんとするかが本考案の課題である。 Therefore, it can be opened and closed quickly, and it does not freeze even in the coldest season, and can be quickly opened and closed. A fire extinguisher that emits water and, of course, can be used stably for a long time. The challenge of this invention is how to provide it.

本考案は、地中、不凍結領域に市販のバタフライ弁等の非常に操作の迅速なバ ルブを設置して主弁とし、それをロッドにより延長して地上で操作するようにし 、主弁の流出口に接続されるチーズと地上の放水部本体をパイプにより接続し 、チーズの下端に圧力差により自動開閉する排水弁を接続することにより基本 的には構成される。 This invention is a very quick-to-operate valve, such as a commercially available butterfly valve, for underground, non-freezing areas. A valve is installed as the main valve, and it is extended with a rod so that it can be operated from the ground. , the cheese connected to the outlet of the main valve and the main body of the above-ground water discharge part are connected by a pipe. , by connecting a drain valve that automatically opens and closes due to pressure difference to the bottom end of the cheese. Basically, it is composed of
【０００６】 前記排水弁は、内部に比重が１より小さい止水球を収容し、その上下に２個の パッキン、および前記止水球に上昇力を与える付勢体を装着し、主弁が開の時は 水圧力により止水球は付勢体を下方に押圧するようにして下側のパッキンに密着 し、主弁が閉のときには付勢体の復元力により止水球は下側のパッキンから離脱 してパイプ内の水を排水させるようにするとともに、排水終了後、地下水位が上 昇したような場合には浮力により止水球が上昇して上側のパッキンに当接するた め、汚水の侵人は防止され、さらに排水弁の下端には汚水や異物の混入をまず防 止すべく、逆止弁を形成してなるものである。[0006] The drain valve houses a water stop bulb with a specific gravity of less than 1 inside, and has two bulbs above and below it. A packing and a biasing body that gives upward force to the water stop bulb are installed, and when the main valve is open, Due to water pressure, the water stop bulb presses the biasing body downward and comes into close contact with the lower packing. However, when the main valve is closed, the water stop bulb separates from the lower packing due to the restoring force of the biasing body. In addition to draining the water in the pipes, the underground water level will rise after draining. If it rises, the water stop bulb will rise due to buoyancy and come into contact with the upper packing. This prevents sewage from entering, and the lower end of the drain valve prevents sewage and foreign matter from entering. In order to prevent this, a check valve is formed.
【０００７】[0007]
図１は本考案の概略を示す装置図であるが、図中１は地中不凍結領域に設置さ れる開閉用の主弁であり、ロッド２により地上部に延長され、ハンドル３に連結 される。主弁１には、市販のバタフライ弁、ボール弁等に代表される回転角度が 少ない、従って操作が非常に迅速なバルブを用いる。 主弁１の流出口側にチーズ４を接続し、チーズ４をパイプ５により上方に延長 して地上の放水部本体６に接続する。 Figure 1 is a diagram showing the outline of the present invention. This is the main valve for opening and closing, which is extended above ground by rod 2 and connected to handle 3. be done. The main valve 1 has a rotation angle such as commercially available butterfly valves, ball valves, etc. Use fewer and therefore very quick to operate valves. Connect the cheese 4 to the outlet side of the main valve 1, and extend the cheese 4 upward through the pipe 5. and connect it to the water discharge section main body 6 on the ground.
【０００８】 チーズ４の下端には排水弁７を接続するが、排水弁７は図２に示すごとく、チ ーズ４の下端にねじ接続された保護ケース８と、保護ケース８の内部上端部に接 続される弁箱上部９と、間に逆流防止パッキン１０、座金１１を介して弁箱上部 ９に接続される弁箱本体１２と、弁箱本体１２内の突起１３に着座する止水パッ キン１４と、その上座に着座する付勢体１５を介して止水パッキン１４のシート 面１６に圧着される、比重が１より小さい止水球１７と、弁箱本体１２の下端に 接続されるプラグ１８およびプラグの上端に形成される弁座１９に自重により着 座する、球状の閉子２０を有する逆止弁２１とにより構成される。[0008] A drain valve 7 is connected to the lower end of the cheese 4, and the drain valve 7 is as shown in FIG. A protective case 8 is screwed to the lower end of the case 4, and a protective case 8 is connected to the inner upper end of the protective case 8. The upper part of the valve box is connected to the upper part of the valve box through the backflow prevention packing 10 and the washer 11 in between. A valve box body 12 connected to the valve body 9 and a water stop pad seated on a protrusion 13 inside the valve body body 12. The seat of the water-stop packing 14 is applied to the water-stop packing 14 via the pusher 14 and the urging member 15 seated on its upper seat. A water stop bulb 17 with a specific gravity smaller than 1 is crimped onto the surface 16 and a water stop bulb 17 is attached to the lower end of the valve body body 12. It attaches to the plug 18 to be connected and the valve seat 19 formed at the upper end of the plug due to its own weight. The check valve 21 has a spherical closure 20 and a seated check valve 21.
【０００９】 プラグ１８は下方部に横穴２２を穿って縦穴２３と連通し、弁箱本体１２の側 方に穿った排水孔２４とバイパス路２５を導通する排水路を形成する。付勢体１ ５は図３のごとく、内方に４個の突起２６をもうけたゴム状弾性体からなり、主 弁１が開いているときには、水圧力により止水球１７が前記突起２６を押し下げ るようにして止水パッキン１４のシート面１６に圧接され、漏水を防止する。[0009] The plug 18 has a horizontal hole 22 in its lower part, communicates with a vertical hole 23, and connects to the side of the valve body 12. A drainage channel is formed which connects the drainage hole 24 bored in the direction and the bypass path 25. Biasing body 1 As shown in Fig. 3, 5 is made of a rubber-like elastic body with four protrusions 26 on the inside. When the valve 1 is open, the water stop bulb 17 pushes down the projection 26 due to water pressure. It is pressed against the sheet surface 16 of the water stop packing 14 in such a manner as to prevent water leakage.
【００１０】 主弁１を閉じたときには前記水圧力がなくなるため、前記突起２６のゴム弾性 による復元力と浮力により止水球１７は上昇してシート面１６との間に隙間が生 じ、パイプ５内の水はその隙間からバイパス路２５、横穴２２、縦穴２３を通っ て閉子２０を上昇させ、排水孔２４から保護ケース８に排出される。保護ケース ８には多数の穴２７を穿っており、その穴２７から地中に排出されることになる 。排出する際には放水部本体６の出口ヘッドまでの水圧力が下向きの力として 止水球１７に作用するため、その水圧力に打ち勝つだけの復元力が突起２６には 必要となる。0010 When the main valve 1 is closed, the water pressure disappears, so the rubber elasticity of the protrusion 26 Due to the restoring force and buoyancy, the water stop bulb 17 rises and a gap is created between it and the seat surface 16. Similarly, the water in the pipe 5 passes through the gap through the bypass passage 25, the horizontal hole 22, and the vertical hole 23. The closing member 20 is raised, and the water is discharged from the drain hole 24 into the protective case 8. protective case 8 has a number of holes 27 drilled in it, and the water will be discharged into the ground through these holes 27. . When discharging water, the water pressure up to the outlet head of the water discharge unit body 6 acts as a downward force. Since it acts on the water stop bulb 17, the protrusion 26 has a restoring force sufficient to overcome the water pressure. It becomes necessary.
【００１１】 排水終了後、降雨などにより地下水位が上昇したようなときには、弁箱本体１ ２内に汚水が侵入しようとするが、閉子２０が弁座１９を閉塞しているため、逆 止弁２１内への汚水あるいは土砂の混入を有効に防止できる。万一、閉子２０が 完全に作動しないで汚水が弁箱本体１２内に侵入しても、止水球１７まで水が達 した場合には浮力により止水球１７は上昇し、逆流防止パッキン１０に当接して それ以上の汚水の混入を防止する。つまり、二重に逆流を防止しているわけであ る 。[0011] After drainage is complete, if the groundwater level rises due to rain, etc., remove the valve box body 1. Sewage tries to enter 2, but since the closure 20 is blocking the valve seat 19, it is reversed. It is possible to effectively prevent sewage or dirt from entering the stop valve 21. In the unlikely event that a closed child of 20 Even if sewage enters the valve body 12 without fully operating, the water will not reach the water stop bulb 17. In this case, the water stop bulb 17 rises due to buoyancy and comes into contact with the backflow prevention packing 10. Prevent further contamination of wastewater. In other words, it doubles the prevention of backflow. Ru.
【００１２】 なお、閉子２０は必ずしも球状である必要はなく、有効に逆流を防止するもの であれば、どんな形状でも構わない。また、弁箱本体１２の側壁に同様の弁座１ ９と閉子２０を有するＬ字状の逆止弁を別体に接続することもできる。付勢体１ ５の数を増減したり、付勢体１５と止水パッキン１４を一体にして、止水パッキ ン１４の上方に突起２６をもうけてもよく、さらには通常の金属ばねなど、ばね 弾性を有するものであれば、どんなものても付勢体１５として使用することが可 能である。0012 Note that the closure 20 does not necessarily have to be spherical, but can effectively prevent backflow. It doesn't matter what shape it is. In addition, a similar valve seat 1 is attached to the side wall of the valve body body 12. An L-shaped check valve having a closure member 9 and a closure member 20 can also be connected separately. Biasing body 1 You can increase or decrease the number of parts 5 or combine the biasing body 15 and the water stop packing 14 to create a water stop packing. A projection 26 may be provided above the spring 14, and a spring such as a normal metal spring may be formed. Any material can be used as the biasing body 15 as long as it has elasticity. It is Noh.

【考案の効果】 以上のように本考案においては、放水部本体と操作部を切り離して操作部には 水が達しないようにしたので、凍結によりハンドル操作が不能になるという事故 もなく、主弁と排水弁を別個にもうけたので、主弁には、例えば市販のバタフラ イ弁等のようにハンドル回転角度が少なく、従って操作が迅速に行われるバルブ を採用することができ、維持管理も容易となり、排水、非排水切換え用の止水球 を浮弁にすることにより一つの逆止弁を形成し、その下流側に、常態では自重に より弁座を閉塞する、もう一つの逆止弁を形成しているので主弁の上流側に負圧 が生じたような場合の本管側への汚水の吸引を完全に防止でき、特に土砂等の混 入による排水弁の動作不良が起こらず、従って長期間安定して使用できる効果が ある。[Effect of the idea] As described above, in this invention, the main body of the water discharge part and the operation part are separated, and the operation part is An accident where the steering wheel became impossible to operate due to freezing because water was prevented from reaching the vehicle. Since the main valve and drain valve are provided separately, the main valve can be used, for example, with a commercially available butterfly valve. Valve such as a valve with a small handle rotation angle and therefore quick operation This makes it easy to maintain and manage, and a water stop bulb can be used to switch between draining and non-draining. By making it a floating valve, a single check valve is formed, and on the downstream side, under normal conditions, the Since it forms another check valve that closes the valve seat, negative pressure is created on the upstream side of the main valve. It can completely prevent the suction of sewage into the main pipe in the event of a The drainage valve does not malfunction due to water leakage, so it can be used stably for a long period of time. be.
