Description
本発明は、小規模建築物用スプリンクラーと水道水の貯水に関するものである。 The present invention relates to a small-scale building sprinkler and tap water storage.
従来、水道を利用するスプリンクラー装置がある(特許文献1参照)。この中で水道本管から分岐した一次側配管口径が40A以上の建物には実用上十分であるが盗水の可能性がある。また、上水道配管から分岐した、同じ系統の水道水が他の分岐水栓から風呂給水などに使用された場合、水量の不足が発生する。(特許文献２参照) Conventionally, there is a sprinkler device that uses water (see Patent Document 1). Of these, it is practically sufficient for buildings with a primary pipe diameter of 40A or more branched from the water main, but there is a possibility of water theft. In addition, when tap water of the same system branched from the water supply pipe is used for bath water supply from other branch taps, a shortage of water occurs. (See Patent Document 2)
また、メーター口径が25A以下の場合は増圧ポンプを付加しても水量が不足する欠点があった。
小規模建築物または、集合住宅や雑居ビルでは個別にメーターが設置され、水道口径が小さい事と、増圧ポンプ用の動力電源がない事などの問題がある。
この改善策として、水道配管と水道メーターを40A以上にして、水道圧力の足らない場合は増圧ポンプ用動力電源を設置し改善する方法もあるが、各契約による基本料金が発生しランニングコストと各設備費が発生した。
In addition, when the meter aperture is 25 A or less, there is a drawback that the amount of water is insufficient even if a booster pump is added.
In small buildings, apartment buildings and multi-purpose buildings, there are problems such as the fact that meters are individually installed, the water diameter is small, and there is no power supply for the booster pump.
As a measure to improve this, there is a method to improve the water supply pipe and water meter to 40A or more and install a power supply for the booster pump if the water pressure is insufficient. Each equipment cost occurred.
加圧用動力電源の必要がなく、スプリンクラー設備に必要な水量、水圧の安定確保と水道と電気の遮断(ライフラインの遮断)が発生しても初期消火が可能なスプリンクラー装置と飲用水の確保を課題とする。 There is no need for a power supply for pressurization, ensuring the amount of water required for the sprinkler equipment, ensuring stable water pressure, and securing a sprinkler device and potable water that can be extinguished at the initial stage even if the water supply and electricity are interrupted (interruption of lifeline) Let it be an issue.
本発明は、災害発生時など水道水が遮断された場合を考慮し、水道水の貯水構造を有し、不活性ガス又は圧縮空気の圧力により送水する事で電力を必要としない装置により解決する。水道水を利用するにあたり、水道水が空気またはガスと接触しない構造で飲用水を確保できる。また各戸のスプリンクラー配管を接続集合させる事で貯水構造部を共有でき、各戸の水道メーターは小さくても、スプリンクラー配管の集合により必要水量と水圧が確保される装置を提供する。 The present invention takes into account the case where tap water is interrupted, such as in the event of a disaster, and has a water storage structure for tap water, which is solved by a device that does not require electric power by supplying water by the pressure of inert gas or compressed air. . When using tap water, drinking water can be secured with a structure in which tap water does not come into contact with air or gas. In addition, the water storage structure can be shared by connecting and collecting the sprinkler pipes of each door, and even if the water meter of each door is small, a device that can secure the required water amount and water pressure by the collection of sprinkler pipes is provided.
本発明のスプリンクラー装置は、集合戸数が多いほど水道水の水量と水圧の確保が容易になり、各戸の設備費用も少なく成るという利点がある。また、貯水構造部の加圧に使用するチューブを利用した装置の場合、常に新しい水道水が確保されるため、緊急時の飲用水確保が可能となる利点がある。 The sprinkler device of the present invention has the advantage that the greater the number of collective houses, the easier it is to secure the amount of tap water and the water pressure, and the equipment cost of each house is reduced. In addition, in the case of an apparatus using a tube used for pressurization of the water storage structure, since new tap water is always secured, there is an advantage that potable water can be secured in an emergency.
感知配管の圧力変動により、スプリンクラー装置を起動し水道水を常に新しく貯水又は消火液を利用し水道水の併用で水道水の水量や水圧が小さくても、又は水道電気が遮断された場合にも初期消火を可能とする目的を、水道水に死に水(停滞水)の発生と逆流を防ぎ実現した。消防設備において消火設備と警報設備は連動した機能が必要であるが本発明の主体は飲用水貯水とスプリンクラー装置の実施方法にあるので、(実施例14)以外の(各実施例)の警報設備との連携機能及びセンサーの説明は省く。 Even if the water amount or water pressure of tap water is small due to the fluctuation of the pressure of the sensing pipe, the sprinkler device is started and tap water is always newly stored or used as a fire extinguishing liquid, and the tap water is low or the water supply is cut off. The purpose of enabling initial fire extinguishing was realized by preventing the occurrence of water (stagnant water) and backflow in the tap water. In the fire fighting equipment, the fire extinguishing equipment and the alarm equipment need to have linked functions, but since the main body of the present invention is the method for implementing drinking water storage and the sprinkler device, the alarm equipment of (each example) other than (Example 14) The description of the linkage function and sensor is omitted.
また、スプリンクラー配管内の圧力保持について乾式と湿式があるが本方式では圧縮空気又は不活性ガスにより圧力保持又は真空保持とするが、実施の場合水圧試験により残水がある事が考えられ、乾式と湿式の判定が困難である。水道水又はスプリンクラーポンプによる水圧保持ではなく、スプリンクラー配管内の残水の有無に関係なく、圧縮空気又は不活性ガスの圧力による圧力保持を表現している。 There are dry and wet methods for maintaining pressure in the sprinkler piping. In this method, pressure or vacuum is maintained with compressed air or inert gas. It is difficult to make a wet determination. It represents not pressure maintenance by tap water or a sprinkler pump but pressure maintenance by pressure of compressed air or inert gas regardless of the presence or absence of residual water in the sprinkler piping.
仮にスプリンクラー配管に水を充満させ圧縮空気又は不活性ガスで圧力保持をしても機器構成は同じであり動作事態に違いは発生しない物とする。実施例の説明において図中の番号で13と14は一体で、減圧装置と表現している。 Even if the sprinkler piping is filled with water and the pressure is maintained with compressed air or inert gas, the equipment configuration is the same and no difference occurs in the operating situation. In the description of the embodiments, numerals 13 and 14 in the figure are integrated and expressed as a decompression device.
また、常に新しく貯水する貯水槽は球形と配管型の五種類あり、指定して表現しない場合は貯水槽と表現している。図14と15ではチューブ構造を持たないので球形と配管型があるがタンクと表現する。
また、制御弁は四種類あるが指定して表現しない場合は制御弁と表現している。
In addition, there are five types of storage tanks that always store new water, spherical and pipe-type. If not specified, it is expressed as a storage tank. In FIGS. 14 and 15, since there is no tube structure, there are a spherical shape and a piping type, but it is expressed as a tank.
Moreover, although there are four types of control valves, they are expressed as control valves when not designated and expressed.
(図1)は本発明の消火装置のシステム図である。(図1)に表記する3は水道管から分岐した各戸の水道メーターである。通常時は3から水道水が31を通り、7から8へ通水し8の中を撹拌しながら停滞水が起こらない状態で制御弁2を経て4に供給される。8の詳細は(図4)に示す。
8の断面図で17の内部に19があり7からの水道水が蓄えられる。水道水が充満し、その圧力で19が17の内壁に張り付く状態が通常時で、17の耐圧力で19は保持され同等の耐圧力となる。19内部の水道水の流れは中間部に設けた22により、水圧差相当分が20に流れ19内部を撹拌しながら回転し18に戻り22を通る水道水と合流し、2の方向へ流れる。この流れは22による水圧抵抗で発生する。
FIG. 1 is a system diagram of a fire extinguishing apparatus according to the present invention. 3 shown in (Fig. 1) is a water meter at each branch branched from the water pipe. Under normal circumstances, tap water from 3 passes through 31 and is supplied to 4 through control valve 2 while passing through 7 to 8 and stirring in 8 without stagnating water. Details of 8 are shown in FIG.
In the sectional view of 8, there are 19 inside 17 and the tap water from 7 is stored. The state where the tap water is filled and the 19 sticks to the inner wall of the 17 by the pressure is normal, and the 19 is held at the withstand pressure of 17, and the equivalent withstand pressure is obtained. The flow of the tap water inside 19 is provided in the middle part 22, the amount corresponding to the water pressure difference flows to 20, rotates while stirring inside 19, returns to 18, merges with the tap water passing through 22, and flows in the direction of 2. This flow is generated by the hydraulic resistance due to 22.
(図1)の46建物Aについて消火動作を説明する。46の室内天井部に1が配置され29と10を通じ配管が2に繋がっている。12は微量の圧縮空気又は不活性ガスを送給し微量の配管漏れに対応した補給装置である。29内部に圧縮空気又は不活性ガスを一定圧力で保持しており、32にも同圧が掛かり10で逆流閉止されて、感知動作となる。1の開放動作で圧力が開放される圧力変動を感知して配管内の圧力低下で32を通じ2と5が作動する制御をしている。2は感知圧力の変動により起動し水道水を屋内給水側からスプリンクラー側へ切り替える動作をする制御弁である。5は感知圧力の変動によりガスボンベの起動を制御する弁である。 The fire extinguishing operation will be described for 46 building A in FIG. 1 is placed on 46 indoor ceilings, and pipes are connected to 2 through 29 and 10. 12 is a replenishing device that feeds a small amount of compressed air or inert gas and copes with a small amount of pipe leakage. Compressed air or inert gas is held at a constant pressure inside 29, and the same pressure is also applied to 32, and the backflow is closed by 10 and a sensing operation is performed. It senses the pressure fluctuation at which the pressure is released by the opening operation of 1, and controls 2 and 5 to operate through 32 when the pressure in the pipe drops. Reference numeral 2 is a control valve that is activated by a change in the sensed pressure and operates to switch tap water from the indoor water supply side to the sprinkler side. Reference numeral 5 is a valve for controlling the start of the gas cylinder by fluctuation of the sensed pressure.
通常時、感知圧力は10で閉止している。10から2に繋がる配管は2を経由して11につながり11により微量の真空引きで一定の不圧状態で保持されている。これは、2の故障による、漏水時に水道水への逆流をなくし、漏水検知をしている。2の詳細は(図9)に示す。5の動作は9に不活性ガス又は不活性液化ガス又は圧縮空気が充填されており、8の貯水量の放出に必要な圧力が維持されるガス量が予め計量してある。32の圧力低下で開放状態となり、44から(8の内部構造図4)17と19の間に不活性ガス又は不活性液化ガスの気化ガス又は圧縮空気を放出し19に一定圧力を加える事で、水道水の圧力が低下又は絶対水量の不足する場合、貯水量に応じ補助する事ができる。 Normally, the sensing pressure is 10 and closed. The pipe connected from 10 to 2 is connected to 11 via 2 and is held in a constant unpressurized state by a small amount of vacuum by 11. This eliminates the backflow to tap water at the time of water leakage due to the failure of 2 and detects water leakage. Details of 2 are shown in FIG. In the operation 5, 9 is filled with an inert gas, an inert liquefied gas, or compressed air, and the amount of gas that maintains the pressure necessary to discharge the water storage amount 8 is measured in advance. When the pressure drops to 32, the open state is reached.From 44 (internal structure diagram 4), the gas or compressed air of inert gas or inert liquefied gas is released between 17 and 19, and a constant pressure is applied to 19 If the tap water pressure drops or the absolute amount of water is insufficient, the amount of water stored can be assisted.
又、断水時にも19に貯水された水量で初期消火できる。この時、水道水の圧力差で逆流が起こらない様に7で閉止している。9から放出されるガス圧の調整は(図4)に示す。9に不活性ガスの種類の内、液化炭酸ガスを想定して説明する。液化炭酸ガスが充填してあり5が開放を行った場合、液体が直接8へ送られれば圧力制御が困難になるおそれがある。13と14(減圧装置)を配置することで一定圧を調整している。 In addition, the initial fire can be extinguished with the amount of water stored in 19 even when there is a water outage. At this time, it is closed at 7 so that backflow does not occur due to the pressure difference of tap water. The adjustment of the gas pressure released from 9 is shown in (Fig. 4). 9 explains the assumption of liquefied carbon dioxide gas among the types of inert gas. When liquefied carbon dioxide is filled and 5 is opened, if the liquid is sent directly to 8, pressure control may be difficult. The constant pressure is adjusted by arranging 13 and 14 (pressure reducing device).
13は空冷式又は水冷式で液体の気化とガスボンベからの放出圧力を減圧する能力があるキャピラリー管で、14の凍りつきを防ぎ圧力の安定化をはかる二段階減圧を特徴としている。また、9に気体窒素が充填されている場合でも14だけでは、減圧動作による低温化が進み動作不良が起こる可能性があるが14の一次側に13を設け、減圧動作により集熱をする事でガス温度の低下を防ぎ、14が安定化する。13は気化集熱と減圧を同時に行え、小型化が容易である。(一定圧とは消火動作に必要な圧力と配管損出計算を計算した圧力)(キャピラリー管は細管を利用した減圧管で水冷、空冷があり、冷凍サイクルなどに利用される方式。また、集熱の量によって圧力が一定ではないので圧力調整弁とはならない)(減圧弁は圧力調整弁で設定した圧力を一定にたもつ) 13 is a capillary tube that is air-cooled or water-cooled and has the ability to reduce the pressure of vaporization and gas cylinder discharge, and is characterized by a two-stage pressure reduction that prevents freezing and stabilizes the pressure. In addition, even if 9 is filled with gaseous nitrogen, if only 14 is used, the temperature may decrease due to the decompression operation and malfunction may occur.However, 13 is provided on the primary side of 14 to collect heat by the decompression operation. Prevents the gas temperature from decreasing and 14 stabilizes. 13 can perform vaporization heat collection and pressure reduction at the same time, and is easy to downsize. (Constant pressure is the pressure required for fire extinguishing operation and pressure calculated for pipe loss calculation) (Capillary tube is a decompression tube using a thin tube, water-cooled and air-cooled, and used in refrigeration cycles, etc. (Because the pressure is not constant depending on the amount of heat, it does not become a pressure regulating valve) (The pressure reducing valve has a constant pressure set by the pressure regulating valve)
(図４)において19の説明をする。19は外部からガスの一定圧力で水道水を圧縮するが31からの流入水量が不足して来ると蓄えた水を搾り出す要領で19がしぼむ形となり、最終的に18に巻き付く様に収縮して行き、20の流れがふさがれる形となるが水道水は22を通過して供給される。 19 will be described in FIG. 19 compresses tap water from the outside with a constant pressure of gas, but when the amount of inflow water from 31 becomes insufficient, 19 becomes a shape that squeezes out the stored water, and finally shrinks to wrap around 18 The tap water is supplied through 22 though the flow of 20 is blocked.
2は二軸が連動して動く四方弁(図9に示す)であり、動作を示す略図である。通常時、水道水は8から37へ入り28を通り38から4へ供給される。この時10から39及び35の配管内は27を通じ40から11により真空引きされ、一定の不圧保持をされる。この状態で10から11までの配管内及び35の内部に水が混入した場合は11により排出と不圧状態による乾燥が起こり経時変化で乾式保持される。消火時、28と27の各軸が連結されて９０度回転して、水道水が37から28を通り35を通じて27を通り39へ送水される。この時40と38は閉止状態となる。二軸四方弁の特徴はL形ポートとT形ポートの組合せにより弁体内に残水が残らない事が特徴である。また、弁の駆動方式はスプリング力、空圧力、不圧力、水圧力、油圧力、電動式、重力式がある。(起動は1の開放による圧力変動でなるが、たとえばスプリング力を圧縮しておいてロックピンで固定し、ダイヤフラムで圧力変動をキャッチしてロックピンを解除する方式と直接駆動する方法がある) Reference numeral 2 denotes a four-way valve (shown in FIG. 9) in which two axes move in conjunction with each other, and is a schematic diagram showing the operation. Normally, tap water enters from 8 to 37 and passes through 28 and is supplied from 38 to 4. At this time, the pipes 10 through 39 and 35 are evacuated through 27 through 40 through 11, and are kept at a constant pressure. In this state, when water is mixed into the pipes 10 to 11 and the inside 35, the water is discharged by 11 and dried due to the non-pressure state, and is kept dry over time. At the time of fire extinguishing, the shafts 28 and 27 are connected and rotated 90 degrees, and tap water is sent from 37 to 28 through 35 to 27 through 39. At this time, 40 and 38 are closed. The characteristic of the biaxial four-way valve is that there is no residual water in the valve body due to the combination of the L-shaped port and the T-shaped port. Further, the valve drive system includes spring force, pneumatic pressure, non-pressure, water pressure, oil pressure, electric type, and gravity type. (Startup consists of pressure fluctuations due to release of 1; for example, there is a method of compressing the spring force and fixing it with a lock pin, catching the pressure fluctuation with a diaphragm and releasing the lock pin, and a direct drive method)
(図1)の47及び48の動作を説明する。47と48は同じ構造の一戸であり46の29と連結することで8を共有している。まず、各戸のどれかが火災となり1が開放動作と成った場合、各戸の2がスプリンクラー側に切り替り、それぞれのメーターから同時に水道水の送水が始まり、開放した1へ集合送水となる。これにより、一戸のメーターが小さくても水量と水圧が増加することで消火に必要な水量の確保が容易となり、8の貯水量は初期消火が行える量で貯水を小さく出来る。 The operations 47 and 48 in FIG. 1 will be described. 47 and 48 are the same structure and share 8 by connecting with 29 of 46. First, if one of the doors becomes a fire and 1 opens, the 2 of each door switches to the sprinkler side, and tap water starts to be sent from each meter at the same time. As a result, even if a single meter is small, the amount of water and the water pressure increase, making it easy to secure the amount of water required for fire extinguishing.
通常時は１から29、32,10迄感知圧保持され、10から２を経て11まで不圧保持される。水道水は3から7と2を経て4へ供給されている。火災発生で消火時はまず1が開放動作し29と32の減圧動作で2が作動しスプリンクラー側に切り替り、水道水が10を通り29を経て開放した1から放出される。例えば、試験的又は故障により29へ通水した場合は15から排水処理を行い復旧するが10から2の配管内の残水は11により排水と乾燥で残水が残らない構造とし不圧を保持する。2の故障で水道水が10から2の管内に漏れてきても不圧による圧力差で逆流する事を防ぎ、排水し乾燥状態となる。 Normally, the sensing pressure is maintained from 1 to 29, 32, and 10 and is maintained from 10 to 2 to 11 without pressure. Tap water is supplied from 3 to 4 via 3 and 7 and 2. At the time of fire extinguishment, 1 is opened first, 2 is activated by pressure reducing operation of 29 and 32, it switches to the sprinkler side, and tap water is released from 1 opened through 29 through 29. For example, if water is passed to 29 due to a test or failure, drainage treatment will be started from 15 and recovered, but residual water in the pipes from 10 to 2 will be drained and dried by 11 so that no residual water will remain and maintain no pressure To do. Even if tap water leaks into the pipe from 10 to 2 due to the failure of 2, it prevents backflow due to pressure difference due to non-pressure, drains and becomes dry.
また、(図１１)の弁は二軸四方弁であるが三方弁を二個組合せた構造の(特許文献４参照)の構成通り、(図１１)の様に35部分に残水がたまり、中間部に弁を設け排水をする必要がある。又、三方弁を二個配置した場合は別々の制御が必要である。 Moreover, although the valve of (FIG. 11) is a biaxial four-way valve, as shown in the configuration of (Patent Document 4) in which two three-way valves are combined (see FIG. 11), residual water is accumulated in 35 portions as shown in (FIG. 11). It is necessary to drain by providing a valve in the middle. In addition, when two three-way valves are arranged, separate control is required.
複数戸の水道メーターからの給水を連結し同時給水が可能に成れば9、5、44、8、6を省き水道水だけの水量で消火動作が可能となる。例、水道メーターが水道本管からでは無く、高層集合住宅に、給水槽と非常用発電施設が整ったビルであれば、ライフラインが遮断されても機能する事となる。 If water supply from multiple water meters is connected and simultaneous water supply is possible, 9, 5, 44, 8, and 6 can be omitted, and fire extinguishing can be performed with only the amount of tap water. For example, if the water meter is not from the water main, but a high-rise apartment building with a water tank and an emergency power generation facility, it will function even if the lifeline is shut off.
既存設備との差異は消火ポンプを省き給水ポンプで兼ねている形となり、設備が簡素化される事になる。また、断水や減水が少ない地域であれば、水道メーターが水道本管から引込みされた建物であっても機能し、価格の多様性で優位となる。 The difference from existing equipment is that the fire pump is omitted and the water supply pump is also used, and the equipment is simplified. Also, in areas where there is little water outage or water reduction, even buildings where water meters are drawn from the water mains will function and will be advantageous in price diversity.
(図２)は本発明の消火装置のシステム図である。図に表記する3は水道管から分岐した各戸の水道メーターである。通常時は3から水道水が31を通り、7から8へ通水し8の中を撹拌しながら停滞水が起こらない状態で制御弁2を経て蛇口4に供給される。(8の詳細は図4)に示す。
8の断面図の説明は(実施例1)で説明しているので省略する。
(FIG. 2) is a system diagram of the fire extinguishing apparatus of the present invention. 3 shown in the figure is a water meter of each house branched from the water pipe. Normally, tap water from 3 passes through 31 and flows from 7 to 8 and is supplied to the faucet 4 through the control valve 2 in a state where stagnant water does not occur while stirring in 8. (Details of 8 are shown in FIG. 4).
The description of the sectional view of FIG. 8 is omitted since it is described in (Example 1).
(図2)の46建物Aについて消火動作を説明する。46の室内天井部に1が配置され29を通じ、配管が制御弁50に繋がっている。１１は微量の真空引きを行い微量の配管漏れに対応した真空装置である。50をかえし29内部を一定の不圧状態を乾式保持し停止している。29につながる32も同様に不圧が掛かり、1の開放動作で不圧が大気開放される圧力変動を検知してなる乾式不圧配管で、1の開放により50と5が作動する制御をしている。 The fire extinguishing operation is described for 46 building A in FIG. 1 is arranged on 46 indoor ceilings, and the pipe is connected to the control valve 50 through 29. Reference numeral 11 denotes a vacuum apparatus that evacuates a minute amount and copes with a minute amount of pipe leakage. 50 is changed and 29 inside is kept in a certain non-pressure state and is stopped. 32, which leads to 29, is also unstressed, and is a dry unstressed pipe that detects pressure fluctuations in which unstressed pressure is released to the atmosphere with the opening action of 1. ing.
50の詳細は(図１０)に示す。5の動作は9に不活性ガス又は不活性液化ガス又は圧縮空気が充填されており、8の貯水量の放出に必要な圧力が維持されるガス量を予め計量してあり、32の圧力変動で開放状態となり、44から17と19の間に不活性ガス又は不活性液化ガスの気化ガス又は圧縮空気を放出し19に一定圧力を加える事で、水の圧力が低下又は絶対水量の不足する場合、貯水量に応じ補助する事ができる。又、断水時にも19に貯水された水量で初期消火できる。この時、水道水の圧力差で逆流が起こらない様に7で閉止している。
9から放出されるガスの調整は(実施例1)で説明しているので省略する。
(図４)において、19の説明は（実施例１）で説明しているので省略する。
Details of 50 are shown in FIG. The operation of 5 is filled with inert gas or inert liquefied gas or compressed air at 9, and the amount of gas that maintains the pressure necessary for discharging the water storage amount of 8 is pre-measured, and the pressure fluctuation of 32 It becomes an open state at 44, and the pressure of water decreases or the amount of absolute water is insufficient by releasing a vaporized gas or compressed air of inert gas or inert liquefied gas between 44 and 17 and 19 and applying a constant pressure to 19 In case, it can assist depending on the amount of water stored. In addition, the initial fire can be extinguished with the amount of water stored in 19 even when the water is shut off. At this time, it is closed at 7 so that backflow does not occur due to the pressure difference of tap water.
The adjustment of the gas released from 9 has been described in (Example 1) and will be omitted.
In FIG. 4, the description of 19 is omitted since it is described in (Example 1).
(図１０)は二軸が連動して動く四方弁であり、動作を示す略図である。通常時、水道水は8から37へ入り28を通り38から4へ供給される。この時1から29、39及び35の配管内は27を通じ40から11により真空引きされ、一定の不圧保持をされる。この状態で1から29、50、11までの配管内及び35の内部に水が混入した場合は11により排出と不圧状態による乾燥が起こり経時変化で乾式保持される。消火時、28と27の各軸が連結されて９０°回転し、水道水が37から28を通り10、35を通じて27を通り39へ送水される。この時40と38は閉止状態となる。10は35の中間部に設けるがスプリンクラー配管の圧力試験用に付加してあるが一連の動作には必要ない物で付加しなくても良い。二軸四方弁の特徴はL形ポートとT形ポートの組合せにより弁体内に残水が残らない事が特徴である。 (FIG. 10) is a four-way valve in which two axes move in conjunction with each other, and is a schematic diagram showing the operation. Normally, tap water enters from 8 to 37 and passes through 28 and is supplied from 38 to 4. At this time, the pipes 1 through 29, 39 and 35 are evacuated through 27 through 40 through 11, and are kept at a certain level of non-pressure. In this state, when water is mixed in the pipes 1 to 29, 50, and 11 and inside 35, the water is discharged by 11 and is dried due to a non-pressure state, and is kept dry over time. During fire extinguishing, the shafts 28 and 27 are connected and rotated 90 °, and tap water is passed from 37 to 28 through 10 and 35 to 27 and 39. At this time, 40 and 38 are closed. Although 10 is provided in the middle part of 35, it is added for the pressure test of the sprinkler pipe, but it is not necessary to add it as a thing unnecessary for a series of operations. The characteristic of the biaxial four-way valve is that there is no residual water in the valve body due to the combination of the L-shaped port and the T-shaped port.
また、弁の駆動方式はスプリング力、空圧力、不圧力、水圧力、油圧力、電動式、重力式がある。(起動は1の開放による圧力変動でなるが、たとえばスプリング力を圧縮しておいてロックピンで固定し、ダイヤフラムで圧力変動をキャッチしてロックピンを解除する方式と直接駆動する方法がある)
(図２)の47及び48の動作を説明する。47と48は同じ構造の１戸であり46の29と連結することで8を共有している。
Further, the valve drive system includes spring force, pneumatic pressure, non-pressure, water pressure, oil pressure, electric type, and gravity type. (Startup consists of pressure fluctuations due to release of 1; for example, there is a method of compressing the spring force and fixing it with a lock pin, catching the pressure fluctuation with a diaphragm and releasing the lock pin, and a direct drive method)
The operations 47 and 48 in FIG. 2 will be described. 47 and 48 are one house of the same structure and share 8 by connecting with 29 of 46.
まず、各戸のどれかが火災となり1が開放動作と成った場合、各戸の2がスプリンクラー側に切り替り、それぞれのメーターから同時に送水が始まり、開放した1へ集合送水となる。これにより、１戸のメーターが小さくても水量と水圧が増加することで消火に必要な水量の確保が容易となり、8の貯水量を小さく出来る。まず、通常時は１から29、32,10、52のスプリンクラーポート迄、46の11により感知乾式不圧保持される。水道水は3から7と52を経て4へ供給されている。火災発生で消火時はまず1が開放動作し29と32の感知不圧が大気開放動作で52が作動しスプリンクラーポート側に切り替り、水道水が10を通り29を経て開放した1から放出される。例えば、試験的又は故障により29へ通水した場合は15から排水処理を行い復旧するが29から10、52の配管内の残水は46の11により排水と乾燥で残水が残らない構造とし不圧を保持する。52の故障で水道水が10から52の管内に漏れてきても不圧保持による圧力差で逆流する事を防ぎ、排水と乾燥で乾式状態となる。
52は(図１７)に示す。本人発明の(特開2004-97503)に記載の制御弁を不圧の大気開放で動作する制御弁(三方弁)にした物である。
複数戸の水道メーターからの給水を連結は(実施例1)で説明しているので省略する。
First, if one of the doors becomes a fire and 1 opens, the 2 of each door switches to the sprinkler side, and water is started from each meter at the same time. As a result, even if a single meter is small, the amount of water and water pressure increase, making it easy to secure the amount of water necessary for fire extinguishing, and the amount of water stored in 8 can be reduced. First, in the normal state, from 1 to 29, 32, 10, and 52 sprinkler ports, the sensing dry-type non-pressure is held by 46-11. Tap water is supplied to 3 through 3 and 7 and 52. When fire extinguishes, 1 first opens, 1 and 29 and 32 sensed pressures are released to the atmosphere, 52 starts and switches to the sprinkler port side, and tap water is released from 1 that has been opened through 29 through 29. The For example, if water is passed to 29 due to a test or failure, drainage will be treated from 15 and recovered, but the remaining water in the pipes 29 to 10 and 52 will be drained and dried according to 46-11 so that no residual water remains. Holds no pressure. Even if tap water leaks into the pipe from 10 to 52 due to the failure of 52, it prevents backflow due to the pressure difference due to non-pressure retention, and it becomes dry by draining and drying.
52 is shown in FIG. This is a control valve (three-way valve) that operates in a non-pressure open atmosphere to the control valve described in the present invention (Japanese Patent Laid-Open No. 2004-97503).
Since the connection of the water supply from a plurality of water meters is described in (Example 1), it will be omitted.
(図３)は本発明の消火装置のシステム図である。(図３)において、(図1)との相違点をのべ、共通する動作は省略する。 FIG. 3 is a system diagram of the fire extinguishing apparatus of the present invention. In FIG. 3, common operations are omitted except for differences from FIG.
(図１)との差異は11の不圧装置が省かれ、10から2の配管は通常時33の排水管により大気開放されている点である。(図９)の40真空ポンプ口(排水口)が33に繋がれ大気開放されている事になる。よって残水は自然的に排水される。また、29に感知用圧縮空気又は不活性ガスが加圧保持されているが10の故障による漏れも排出され水道水への混入は防げる構造となる。消火時には40と38が閉止状態となり水道水の排水を閉止する。(図１)の場合は10と2の漏れにより、不圧装置の圧力を保持する機能で不圧装置が起動する事による漏れ検知が可能となるが、(図３)の場合は大気開放により漏れ検知が難しくなる点にあるが、構造が簡素化される。
複数戸の水道メーターからの給水を連結は(実施例1)で説明しているので省略する。
The difference from (Fig. 1) is that 11 pressureless devices are omitted and 10 to 2 pipes are normally opened to the atmosphere by 33 drain pipes. The 40 vacuum pump port (drain port) in Fig. 9 is connected to 33 and is open to the atmosphere. Therefore, the remaining water is drained naturally. In addition, although compressed air or inert gas for pressure is held at 29, leakage due to 10 failures is also discharged, and mixing into tap water is prevented. When fire extinguishes, 40 and 38 are closed and the tap water drainage is closed. In the case of (Fig. 1), it is possible to detect leaks by starting the incompressible device with the function of holding the pressure of the incompressible device due to leakage of 10 and 2, but in the case of (Fig. 3) Although it is difficult to detect leaks, the structure is simplified.
Since the connection of the water supply from a plurality of water meters is described in (Example 1), it will be omitted.
(図４)は本発明の球形貯水槽である。(請求項1記載)( 図４)は断面図で17の内部に19があり31からの水道水が19に蓄えられる。水道水が充満し、その圧力で19が17の内壁に張り付く状態となり17の耐圧力で19は保持され同等の耐圧力となる。6は加圧ガスによる許容耐圧用の安全弁である。 (FIG. 4) is a spherical water tank of the present invention. (Claim 1) (FIG. 4) is a cross-sectional view, with 19 inside 17 and the tap water from 31 is stored in 19. When tap water is filled, 19 sticks to the inner wall of 17 by the pressure, and 19 is held at the withstand pressure of 17 and has the same withstand pressure. 6 is a safety valve for allowable pressure resistance with pressurized gas.
19内部の水道水の流れは31から18に流れ中間部に設けた22により、水圧差相当分が20に流れ19内部を撹拌しながら18に戻り22を通る水道水と合流し2の方向へ流れる。この流れは22による水圧抵抗で発生する。22は水圧抵抗が増せば流路を拡大する弁でも良い。5、9、13、14の説明は(実施例1)で説明しているので省略する。(22はオリフィスまたは水圧抵抗が増せば流路を拡大する弁) The flow of tap water inside 19 flows from 31 to 18, and the portion corresponding to the difference in water pressure flows to 20, and the inside of 19 returns to 18 while stirring inside 19 and merges with tap water passing through 22 in the direction of 2. Flowing. This flow is generated by the hydraulic resistance due to 22. 22 may be a valve that expands the flow path if the hydraulic resistance increases. Descriptions of 5, 9, 13, and 14 are omitted since they are described in (Example 1). (22 is a valve that expands the flow path if the orifice or water pressure resistance increases)
19内の水道水は常に新しい水が蓄えられる構造で、15と16を設ける事により各配管から切り離せる様にし、緊急時の飲用水に利用可能となる。また、移動ができるため使用範囲が広がり災害時の貯蔵飲用水として利用できる。下側配管フランジから水道水を取り出す事も可能である。 The tap water in 19 is a structure in which new water is always stored. By installing 15 and 16, it can be separated from each pipe and can be used for drinking water in an emergency. In addition, since it can be moved, it can be used as stored drinking water in the event of a disaster. It is also possible to take tap water from the lower piping flange.
(図５)は本発明の球形貯水槽である。(図５)は断面図で17の内部に19があり31からの水道水が17に蓄えられる。水道水が充満し、その圧力で19が17の内壁に張り付く状態で収縮している。 (FIG. 5) is a spherical water tank of the present invention. (Fig. 5) is a cross-sectional view, with 19 inside 17 and the tap water from 31 is stored in 17. The tap water is full, and the pressure is shrinking with 19 sticking to the inner wall of 17.
18は撹拌用に多数の穴が設けてあり17内部の水道水の流れは31から18へ流れ中間部に設けた22により、水圧差相当分が20に流れ17内部を撹拌しながら18に戻り22を通る水道水と合流し2制御弁の方向へ流れる。この流れは22による水圧抵抗で発生する。(図４)との差異は19加圧チューブの外側からガス圧力をかけるのに対し、図５は19内部にガス圧力を加え水道水を加圧する。この時19加圧チューブは浮力により上部から膨らむ形となり、最終的には17内部の水道貯水が無くなる。19は18と17に張り付く形となり31からの水道水は22を通過する事になる。22は水圧抵抗が増せば流路を拡大する弁でも良い。 18 has a number of holes for stirring, and the flow of tap water in 17 flows from 31 to 18, and the water pressure difference corresponding to 22 flows to 20 and returns to 18 while stirring 17 Merges with tap water passing through 22 and flows in the direction of 2 control valves. This flow is generated by the hydraulic resistance due to 22. The difference from FIG. 4 is that gas pressure is applied from the outside of the 19 pressurizing tube, while FIG. 5 pressurizes tap water by applying gas pressure inside 19. At this time, the 19 pressure tube swells from the upper part due to buoyancy, and eventually the water supply in 17 is lost. 19 sticks to 18 and 17, and the tap water from 31 passes through 22. 22 may be a valve that expands the flow path if the hydraulic resistance increases.
(図６)は本発明の配管型貯水槽である。(図６)は断面図で21の内部に19があり31からの水道水が19に蓄えられる。水道水が充満し、その圧力で19が21の内壁に張り付く状態となり21の耐圧力で19は保持され同等の耐圧力となる。
19は往路と復路があり31接続口付近に22が設けてある。19内部の水道水の流れは31から19の往路に流れ19の末端で復路に流れる。これにより停滞水が無く水道給水する構造である。22は往路の水圧抵抗が増せば流路を拡大する弁でも良い。
(FIG. 6) is a pipe-type water storage tank of the present invention. (Fig. 6) is a cross-sectional view, with 19 inside 21 and the tap water from 31 is stored in 19. When tap water is filled, 19 sticks to the inner wall of 21 by the pressure, and 19 is held at the withstand pressure of 21 and has an equivalent withstand pressure.
19 has an outbound route and a return route, and 22 is provided near 31 connection port. The flow of tap water inside 19 flows from 31 to 19 and then returns to the return at the end of 19. As a result, there is no stagnant water and water supply is provided. 22 may be a valve that expands the flow path if the forward hydraulic resistance increases.
消火時、加圧ガスが21の末端から供給され19を加圧収縮して送水する。この時、19内の往復路は潰され通水が出来なくなるが22が圧力差でバイパス回路の働きを行い、水道水と水道貯水が圧力差に比例して2へ供給される構造である。この時(図6)では22の取り付け位置が21内の隔壁より内側の給水入口の直近に配置されているが、隔壁の外にバイパス配管を取り付け、その配管中間部に22を配置する事も可能である。(図６)の配管型構造は設置場所の応用が利き、内部点検も容易となる。また、(図15)の様に制御機器を配管内部に収納できる利点がある。 During fire extinguishing, pressurized gas is supplied from the end of 21 and 19 is pressurized and contracted to feed water. At this time, the reciprocating path in 19 is crushed and water cannot be passed, but 22 works as a bypass circuit with a pressure difference, and tap water and water storage water are supplied to 2 in proportion to the pressure difference. At this time (Fig. 6), the attachment position of 22 is arranged in the immediate vicinity of the water supply inlet inside the partition wall in 21, but it is also possible to attach a bypass pipe outside the partition wall and arrange 22 in the middle of the pipe. Is possible. The pipe-type structure (Fig. 6) can be applied at the installation site and facilitates internal inspection. Moreover, there is an advantage that the control device can be accommodated in the pipe as shown in FIG.
(図７)は本発明の配管型貯水槽である。(図７)は平面図で(図４)の17を21の配管型に置換えたものであり、作用は(実施例4)と同じであるので省略する。また配管型の利点は設置場所の応用が利き、内部点検も容易となる点である。また、(図15)の様に制御機器を配管内部に収納できる利点がある。 (FIG. 7) is a pipe-type water storage tank of the present invention. (FIG. 7) is a plan view in which 17 in FIG. 4 is replaced with 21 pipe types, and the operation is the same as in (Example 4), and is omitted. The advantage of the piping type is that the installation location can be applied and the internal inspection is easy. Moreover, there is an advantage that the control device can be accommodated in the pipe as shown in FIG.
(図８)は本発明の配管型貯水槽である。(図８)は断面図で(図５)の17の球形タンクを21の配管型に置換えたものであり、作用は(実施例５)と同じであるので省略する。また配管型の利点は設置場所の応用が利き、内部点検も容易となる点である。また、(図15)の様に制御機器を配管内部に収納できる点が利点である。 (FIG. 8) is a pipe-type water storage tank of the present invention. (FIG. 8) is a cross-sectional view in which the 17 spherical tanks of (FIG. 5) are replaced with 21 pipe types, and the operation is the same as in (Example 5), and is omitted. The advantage of the piping type is that the installation location can be applied and the internal inspection is easy. Further, as shown in FIG. 15, the control device can be accommodated inside the pipe.
(図１２)は本発明の制御弁である、一軸一ポート六方弁。(図１２)は断面図で、通常時水道水が37から38へ通水される。この時26が36でシールドされる。点検時などにスプリンクラー配管内に残水が発生しても39から40へ排水され、又は真空引きされ、水道水に混入しない構造となる。また、故障により36が漏水を起こしても49から排水される二重シールド構造である。 FIG. 12 is a one-shaft one-port six-way valve that is a control valve of the present invention. (FIG. 12) is a cross-sectional view, and normal-time tap water is passed from 37 to 38. At this time, 26 is shielded by 36. Even if residual water is generated in the sprinkler piping at the time of inspection, etc., it will be drained from 39 to 40 or evacuated and will not mix with tap water. In addition, even if 36 leaks due to failure, it is a double shield structure that drains from 49.
消火時、26が回転して、水道水が37から39へ通水され、38、40、49は26と36により閉止される。この後、通常時の位置に26が復旧した場合、26弁体内の残水は49から排水される。なお、49が二口あるが一口でも機能する。一軸一ポート五方弁の場合、重力による排水を行う必要がある。この一軸一ポート六方弁は2又は50に置換える事が出来る。また、弁の駆動方式はスプリング力、空圧力、不圧力、水圧力、油圧力、電動式、重力式がある。(起動は1の開放による圧力変動でなるが、たとえばスプリング力を圧縮しておいてロックピンで固定し、ダイヤフラムで圧力変動をキャッチしてロックピンを解除する方式と直接駆動する方法がある) At the time of fire extinguishing, 26 rotates and tap water is passed from 37 to 39, and 38, 40 and 49 are closed by 26 and 36. Thereafter, when 26 is restored to the normal position, the remaining water in the 26 valve body is drained from 49. In addition, there are 49 mouthfuls, but even a bite will work. In the case of a uniaxial one-port five-way valve, it is necessary to drain by gravity. This 1-axis 1-port 6-way valve can be replaced with 2 or 50. Further, the valve drive system includes spring force, pneumatic pressure, non-pressure, water pressure, oil pressure, electric type, and gravity type. (Startup consists of pressure fluctuations due to release of 1; for example, there is a method of compressing the spring force and fixing it with a lock pin, catching the pressure fluctuation with a diaphragm and releasing the lock pin, and a direct drive method)
(図１３)は本発明の制御弁である、スライド回転軸五方弁。(図１３)は制御弁の横断面図と縦断面図で、通常時は(０度)と表記している。26の弁体に41と51が設けてあり水道水は37から38へ通水される。この時、51は25で閉止、49は26で閉止、39は40より真空引き又は排水状態となる。 FIG. 13 is a slide rotation shaft five-way valve which is a control valve of the present invention. (FIG. 13) is a cross-sectional view and a vertical cross-sectional view of the control valve, and is normally expressed as (0 degree). 41 and 51 are provided in 26 valve bodies, and tap water is passed from 37 to 38. At this time, 51 is closed at 25, 49 is closed at 26, and 39 is vacuumed or drained from 40.
排水時は(90度)と表記している。26が(90度)回転と横スライドをして移動し41が横方向に向く。この時スプリンクラー配管内に残水がある場合は39から51、41、49へと排水される。また、弁体内の残水も排水される。この時、37,38,40は26により閉止されている。 When draining, it is written as (90 degrees). 26 (90 degrees) rotates and slides horizontally, 41 moves sideways. At this time, if there is residual water in the sprinkler pipe, it is drained from 39 to 51, 41, 49. In addition, residual water in the valve body is also drained. At this time, 37, 38, and 40 are closed by 26.
消火時は(180度)と表記している。26が(180度)回転と横スライドして移動する。水道水は37から39に通水され、38、40、49が26により閉止、51は25により閉止される。この後、通常の位置に復旧する場合は(90度)の位置で一旦停止し、残水の排水を行い弁体内の水を排水して後、(0度)に復旧する。そこで、スプリンクラー配管内の一部に残水が存在していても真空引きにより経時変化で乾燥する事となる。このスライド回転軸五方弁は2又は50に置換えることが出来る。また、弁の駆動方式はスプリング力、空圧力、不圧力、水圧力、油圧力、電動式、重力式がある。(起動は1の開放による圧力変動でなるが、たとえばスプリング力を圧縮しておいてロックピンで固定し、ダイヤフラムで圧力変動をキャッチしてロックピンを解除する方式と直接駆動する方法がある) It is written as (180 degrees) when extinguishing. 26 moves (180 degrees) and slides sideways. Tap water is passed from 37 to 39, 38, 40, and 49 are closed by 26, and 51 is closed by 25. After that, when returning to the normal position, stop at the position of (90 degrees), drain the remaining water, drain the water in the valve body, and then recover to (0 degree). Therefore, even if residual water is present in a part of the sprinkler pipe, it is dried over time by evacuation. This slide rotary shaft five-way valve can be replaced with 2 or 50. Further, the valve drive system includes spring force, pneumatic pressure, non-pressure, water pressure, oil pressure, electric type, and gravity type. (Startup consists of pressure fluctuations due to release of 1; for example, there is a method of compressing the spring force and fixing it with a lock pin, catching the pressure fluctuation with a diaphragm and releasing the lock pin, and a direct drive method)
(図１４)は本発明の消火装置のシステム図である。(図１４)は断面図で球形消火液水槽(タンク)に吐水空間を持つ事を特徴としている。水道水は31から3、23、2又は50を経て4に屋内給水される。12から32がつながる5、45、2又は50と32から分岐して10を通り29から55、1まで圧縮空気又は不活性ガスによる圧力保持をしている。42には水道水又は消火液が吐水空間ラインまで貯水してあり、この水位はセンサーにより管理されている。5から13,14,44へ加圧ガス配管が設置され突出口は吐水空間の上部に設けてあるが圧力は掛かっていない。6は安全弁である。42から45、54へ通気管が大気開放されている。42から24が55へ配管してあり29へ繋がっている。この時24は42の水道水又は消火液が流れ込んでいる。２又は50のスプリンクラー配管口から53、7、23を通り42の吐水空間上部に配管が繋がっている。

FIG. 14 is a system diagram of the fire extinguishing apparatus of the present invention. (FIG. 14) is a sectional view and is characterized in that a spherical fire extinguishing liquid water tank (tank) has a water discharge space. Tap water is supplied indoors from 31 to 3, 23, 2 or 50. Branches from 5, 45, 2 or 50 and 32 to which 12 to 32 are connected, passes through 10, and maintains pressure with compressed air or inert gas from 29 to 55, 1. In 42, tap water or fire extinguishing liquid is stored up to the water discharge space line, and this water level is controlled by a sensor. Pressurized gas piping is installed from 5 to 13, 14, 44, and the projecting port is provided in the upper part of the water discharge space, but no pressure is applied. 6 is a safety valve. From 42 to 45, 54 the vent pipe is open to the atmosphere. 42 to 24 are piped to 55 and connected to 29. At this time, 42 tap water or fire extinguishing liquid is flowing into 24. The pipe is connected to the upper part of the water discharge space of 42 through 53, 7, 23 from 2 or 50 sprinkler piping ports.
Reference numeral 12 denotes a compressor or an inert gas device that feeds a small amount of compressed air, and is a device that compensates for a decrease in the sensed pressure due to pipe leakage and has a built-in check.
消火時の動作説明、1が火災感知で開放し29、32内部の感知エアー又は感知不活性ガスが1から放出され圧力が変動する。この圧力変動(圧力低下)で5、45、2又は50が動作する。45は閉止し、2又は50はスプリンクラー側に水道水を供給する。水道水は53、7、23を通り42へ供給され42内部が徐々に圧縮されて行き、24から55、29を通り1から水道水又は消火液が放出される。同時に9が5により開放され不活性ガス又は液体不活性ガスが13を通り減圧と気化及び集熱を行い14で圧力調整し44を通り吐水空間に放出し消火液又は水道水を加圧する。44から分岐して6が設けてある。水道水の圧力と加圧ガスの圧力が同時に42へ掛かるが圧力バランスによる比率でそれぞれ供給される。 Operation explanation at the time of fire extinguishing, 1 is opened by fire detection, 29, 32 sensing air or sensing inert gas is released from 1 and the pressure fluctuates. This pressure fluctuation (pressure drop) activates 5, 45, 2 or 50. 45 closes and 2 or 50 supplies tap water to the sprinkler side. Tap water is supplied to 42 through 53, 7, and 23, and the inside of 42 is gradually compressed, and tap water or fire extinguishing liquid is discharged from 1 through 24 to 55 and 29. At the same time, 9 is opened by 5 and the inert gas or liquid inert gas is depressurized, vaporized and collected through 13 and the pressure is adjusted at 14 and discharged to the water discharge space through 44 to pressurize the fire extinguishing liquid or tap water. Branching from 44, 6 is provided. The pressure of tap water and the pressure of pressurized gas are applied to 42 at the same time, but are supplied at a ratio of the pressure balance.
これにより貯水量は水道水が供給されながらスプリンクラーヘッドから放射され、水道水の供給量分だけ42の貯水量が少なく設定できる。また、貯水には水道水にかぎらず消火液が搭載できる点にある。これは、吐水空間があり消火液が水道水へ逆流する事をふせぐ為であり、加圧ガスの水道水への混入を防ぐ機構として7が設けてある。この時、7の故障により加圧ガスが逆流した場合は53のフロート機構により気体の放出を行う。53は作用的には排除しても良いが安全上設けてある。 As a result, the amount of water stored is radiated from the sprinkler head while tap water is being supplied, and the amount of water stored in 42 can be set as small as the amount of tap water supplied. In addition, fire extinguishing liquid can be installed in the water storage, not limited to tap water. This is to prevent the fire extinguishing liquid from flowing back into the tap water because there is a water discharge space, and 7 is provided as a mechanism for preventing the pressurized gas from mixing into the tap water. At this time, if the pressurized gas flows backward due to the failure of 7, the gas is released by the float mechanism 53. 53 may be operatively excluded, but is provided for safety.
また、制御弁に50を使用すれば内部に逆止弁を搭載しているのでダブルチャッキとなり安全度が増す。45は1の開放で起動する閉止弁である。(圧力バランスとは、水道水は地域や建物階でことなる。14からの圧縮空気または不活性ガスの圧力は消火動作に必要な圧力と配管損出計算値の合計で設定される。バランス状態ではガス圧は一定であるが水道水は地域変動の減圧や断水により変化する事の意味であり、各実施例の同時加圧の場合と同じである) In addition, if 50 is used for the control valve, a check valve is installed inside, so double check is used and safety is increased. 45 is a closing valve that is activated when 1 is opened. (Pressure balance refers to the area or building floor of tap water. The pressure of compressed air or inert gas from 14 is set by the sum of the pressure required for fire fighting and the calculated value of pipe loss. Balance state (In this case, the gas pressure is constant, but tap water means that it changes due to regional fluctuations due to depressurization or water outage, which is the same as the case of simultaneous pressurization in each example)
(図１５)は本発明の消火装置のシステム図である。(図１５)は断面図で、配管型消火液水槽(タンク)に吐水空間を持つ事を特徴としている。作用は(実施例１１)と同じで42を56に置換えた構造であるため説明を省略する。配管型の利点は設置場所の応用が利き、内部点検も容易となる点である。また、制御機器を配管内部に収納できる利点がある。 FIG. 15 is a system diagram of the fire extinguishing apparatus of the present invention. (FIG. 15) is a cross-sectional view, characterized by having a water discharge space in a pipe-type fire extinguishing liquid water tank (tank). The operation is the same as in (Example 11), and 42 is replaced with 56, so that the description thereof is omitted. The advantage of the piping type is that the installation location can be applied and the internal inspection is easy. Moreover, there exists an advantage which can accommodate a control apparatus in piping inside.
(図１６)は本発明の消火装置のシステム図である。(図１６)は屋内水道配管の末端部に(実施例1、2、3、11、12)のシステムを接続した場合の実施方法を示した図面である。システム(実施例1、2、3、11、12)は水道メーター直下にシステムを接続する事により水道水の供給を最大限利用するものであり、3とシステムをつなぐ配管途中に分岐した屋内給水がある場合に、たとえば風呂給水が行われた時に消火動作と成った場合、水道水の供給能力が低下し水量が少なくなる。(図１６)では3とシステムをつなぐ31から分岐した配管部に1の開放による感知圧制御で動作する閉止弁45を設ける事で給水能力の低下を防ぐ機構を付加する事を特徴としている。また、この方式ではシステムを離れた倉庫等別棟に設置でき、屋内給水の水圧低下を防ぐ事が出来る。 FIG. 16 is a system diagram of the fire extinguishing apparatus of the present invention. (FIG. 16) is a drawing showing an implementation method when the system of (Examples 1, 2, 3, 11, 12) is connected to the end of an indoor water pipe. The system (Examples 1, 2, 3, 11, 12) uses the maximum supply of tap water by connecting the system directly under the water meter, and the indoor water supply branched in the middle of the piping connecting 3 and the system If there is a fire extinguishing operation, for example, when bath water is supplied, the supply capacity of tap water is reduced and the amount of water is reduced. (FIG. 16) is characterized in that a mechanism for preventing a reduction in water supply capacity is added by providing a shut-off valve 45 that operates by sensing pressure control by opening 1 in a pipe part branched from 31 connecting system 3 and 31. In addition, this system can be installed in a separate building such as a warehouse away from the system, and can prevent a drop in the water pressure of indoor water supply.
(図18)は本発明の消火装置のシステム図である。図に表記する3は水道管から分岐した各戸の31に配置された水道メーターである。 FIG. 18 is a system diagram of the fire extinguishing apparatus of the present invention. 3 shown in the figure is a water meter arranged in 31 of each branch branched from the water pipe.
通常時は3から水道水が31により、63、7、64へ通水し71の中間から分岐して66、70、72を通り屋内給水へ供給される。この、屋内給水管は71の各所から分岐可能で建物の形状に対応できる。この分岐配管による給水は配管抵抗の圧力損失を防ぐ事にも有効である。また、この分岐配管は設けなくてもよい。水道水は71を通り65から貯水槽内の18へつながり常に新しい水道水の貯水を行う。貯水槽を経由して73の中間に70を配置して4へ通水される。1は71の各所に配置されている。 Under normal circumstances, tap water from 3 is passed through 63 to 63, 7 and 64, branching from the middle of 71 and supplied to indoor water supply through 66, 70 and 72. This indoor water supply pipe can be branched from 71 places and can correspond to the shape of the building. The water supply by this branch pipe is also effective in preventing the pressure loss of the pipe resistance. Further, this branch pipe need not be provided. Tap water passes through 71 and connects from 65 to 18 in the water tank, and always stores new tap water. 70 is placed in the middle of 73 through the water tank and water is passed to 4. 1 is located in 71 places.
貯水槽の説明では、17の内部に19があり71からの水道水が18により19に蓄えられる。水道水が充満し、その圧力で19が17の内壁に張り付く状態となり17の耐圧力で19は保持され同等の耐圧力となる。6は加圧ガスによる許容耐圧用の安全弁である。19内部の水道水の流れは71から18に流れ中間部に設けた22により、水圧差相当分が20に流れ19内部の水道水を撹拌しながら18に戻り、22を通る水道水と合流し遮断弁70の方向へ流れる。この流れは22による水圧抵抗で発生する。22は水圧抵抗が増せば流路を拡大する弁でも良い。17に44がつながり、44が分岐して68、69へ接続されている。さらに44は14、13へつながり67に接続されている。 In the description of the water tank, there are 19 inside 17, and tap water from 71 is stored in 19 by 18. When tap water is filled, 19 sticks to the inner wall of 17 by the pressure, and 19 is held at the withstand pressure of 17 and has the same withstand pressure. 6 is a safety valve for allowable pressure resistance with pressurized gas. The flow of tap water in 19 flows from 71 to 18, and the portion corresponding to the difference in water pressure flows to 20, and the tap water in 19 returns to 18 while stirring, and merges with tap water passing through 22. It flows in the direction of the shut-off valve 70. This flow is generated by the hydraulic resistance due to 22. 22 may be a valve that expands the flow path if the hydraulic resistance increases. 44 is connected to 17 and 44 is branched and connected to 68 and 69. Further, 44 is connected to 14 and 13 and connected to 67.
制御方法は、電気と通信により制御している。建物電源から61へ電力供給され61で電気を蓄え74により62へ供給され制御している。62から60を通じ各機器の63、64、65、66、67、69、70へつながっている。61は無停電電源装置で、停電時に消火動作に必要な電気を供給出来る容量がある。 The control method is controlled by electricity and communication. Electricity is supplied from the building power supply to 61, and electricity is stored in 61 and supplied to 62 by 74 for control. From 62 to 60, it is connected to 63, 64, 65, 66, 67, 69, 70 of each device. 61 is an uninterruptible power supply, which has the capacity to supply electricity necessary for fire fighting operation in the event of a power failure.
通常時の説明をする。水道水は各機器を通過し遮断弁70開で４蛇口に供給されているが、一時的な水道の減圧または断水に対応する構造で、圧力センサー63が減圧信号を発し、コントロール制御装置が69を作動させ、圧縮空気が68を通過し44から17内部へ送給されチューブ19を一定圧で加圧し貯水量に応じて各4へ供給する手段を装備する。(一定圧とは水道水を供給できる最低限の圧力である。最低限の圧力は地域の水道法できまる)この装置により一時的断水と緊急災害時(火災時以外)の飲用水の確保が行える。(図18と図19の違いについて説明しておく。図19は、別々の貯水槽を直列に二台設けた図である。火災時と飲用水を同時に確保できるが貯水槽を並列に設けた場合は二台の貯水槽の循環水量のバランスを考慮する必要があり、直列の場合は水道水の圧力損失を考慮する必要がある。図19の機器配置では73に貯水槽を追加し68を省き69から追加した貯水槽へ接続する。) 圧力センサ63は69の起動と減水、断水信号を出す役目を行う。(チューブ19について、材質では水道水に進出のない物で水道法の規定による。伸縮状またはシート状でテフロン（登録商標）、シリコーン、塩化ビニルがある、他の材質の表面に張り合わせた物や塗布した物があり、テフロン（登録商標）、シリコーン、塩化ビニルを含有した材質がある) The normal explanation is given. The tap water passes through each device and is supplied to the four faucets when the shut-off valve 70 is opened. However, the pressure sensor 63 generates a pressure reduction signal and the control control device 69 , And a means is provided for supplying compressed air through the 68 through the pipe 44 to the inside 17 to pressurize the tube 19 at a constant pressure and supply it to each 4 according to the amount of stored water. (Constant pressure is the minimum pressure at which tap water can be supplied. The minimum pressure is determined by the local water supply law.) This device can ensure temporary water outages and ensure drinking water in the event of an emergency disaster (other than during a fire). Yes. (The difference between Fig. 18 and Fig. 19 will be described. Fig. 19 is a diagram in which two separate water tanks are provided in series. In the event of a fire and drinking water can be secured simultaneously, water tanks are provided in parallel. In this case, it is necessary to consider the balance of the circulating water volume between the two water tanks, and in the case of series connection, it is necessary to consider the pressure loss of tap water. The pressure sensor 63 serves to start 69, reduce water, and issue a water shut-off signal. (The tube 19 is made of material that does not enter tap water, and is subject to the provisions of the Water Supply Law. There are stretched or sheet-like materials such as Teflon (registered trademark), silicone, and vinyl chloride that are bonded to the surface of other materials. (There are applied materials, and there are materials containing Teflon (registered trademark), silicone, and vinyl chloride)
消火時の説明をする。64,65,66は流量センサー(流量計)(65は正逆両方向計測型)である。コントロール制御装置は64の流量数値から65と66の数値の和を比較して差異により1の開放動作を検出する。1の開放による水量は15Ｌ/分以上であるため多少の配管漏れや流量センサーの誤差は比較にならない事からコントロール制御に余裕を持たせ誤動作を防ぐ事ができる。 Explain at fire extinguishing. 64, 65, 66 are flow sensors (flow meters) (65 is a forward / reverse bidirectional measurement type). The control device compares the sum of the 65 and 66 values from the 64 flow rate values, and detects the opening operation of 1 by the difference. Since the amount of water due to the opening of 1 is 15L / min or more, some piping leaks and flow sensor errors are not comparable, so control control can be afforded to prevent malfunctions.
71から分岐する72を複数個所に設ける場合も66と70を配置すればコントロール制御の演算による1の開放検出は可能である。また、分岐を設けない場合も64と65の比較演算を行い1の開放検出はできる。 Even when 72 branches from 71 are provided at a plurality of locations, if 66 and 70 are arranged, it is possible to detect 1 open by calculation of control control. Even when no branch is provided, 64 and 65 are compared and 1 can be detected.
既存設備のスプリンクラー装置では1の開放検出にはアラーム弁を使用するが(ON,OFF)動作のため、様々な水量に対応する本システムの流量センサーに置き換える事はできない。 The sprinkler system of existing equipment uses an alarm valve to detect 1 opening (ON, OFF), but it cannot be replaced with the flow sensor of this system that supports various water volumes.
コントロール制御装置は1の開放検出により72、73に配置した70へ60で送電して遮断を行い67も電磁ロックが開放して9の不活性ガスまたは圧縮空気を放出し13,14,44を経由して17から19を所定圧で圧縮する。この時44の圧力が69からの圧力より高い場合は68により逆流をふせぐ。19内部の水道水が18から71へ送水され、断水でなければ31からの給水も71からの送水との圧力バランスによる水量で1から放水状態となる。(所定圧とは、消火に必要な流量と圧力が得られる値以上の圧力である)
また、図には表記していないが電気的絶縁および耐震および貯水槽の着脱を行うため、バルブ、フランジ、フレキシブルジョイントを設ける。
The control control device detects the opening of 1 and transmits power to 70 arranged at 72 and 73 at 60 and shuts off. 67 also releases the electromagnetic lock and releases 9 inert gas or compressed air to release 13, 14, 44. Compresses 17 to 19 with a predetermined pressure via. At this time, if the pressure of 44 is higher than the pressure from 69, the backflow is blocked by 68. 19 The tap water in the interior is fed from 18 to 71, and if water is not cut off, the water supply from 31 is discharged from 1 with the amount of water due to the pressure balance with the water delivered from 71. (Predetermined pressure is a pressure that is equal to or greater than the flow rate and pressure required for fire extinguishing)
Although not shown in the figure, valves, flanges, and flexible joints are provided for electrical insulation, earthquake resistance, and water tank installation / removal.
以上各実施例中の貯水槽は施工後において追加が可能である。この事によって、将来に建物の増築及びリニューアルに対応でき、貯水量を増やせば小さい子供の施設(学校など)に断水時等また災害時に対応できるので衛生面においても優位である。既存のスプリンクラー設備では水槽は有るものの密閉された循環水でないため衛生的に飲用水に対応出来ないからである。また本発明の送水圧力は貯水槽内の水を最後まで一定圧力で送水できるため水道につながる機器の誤動作が防げる上、短時間の断水や減圧であれば使用者が不自由しないバックアップ機能が可能である。(貯水圧送用コンプレッサーは手動式エアーポンプでも可能で断水時に飲用水の補給に対応できる)(誤動作機器、瞬間湯沸し器など)(短時間とは貯水量の放出時間) As described above, the water storage tank in each embodiment can be added after the construction. In this way, the building can be expanded and renewed in the future, and if the amount of stored water is increased, it can be used in small children's facilities (schools, etc.) in the event of a water outage or in the event of a disaster. This is because existing sprinkler equipment has a water tank, but is not sealed circulating water, so it cannot handle drinking water in a sanitary manner. In addition, the water supply pressure of the present invention allows water in the water tank to be supplied at a constant pressure to the end, preventing malfunctions of equipment connected to the water supply, and a backup function that does not inconvenience the user if water is shut off or decompressed for a short time. It is. (The compressor for pumping water storage can also be a manual air pump, and can respond to replenishment of drinking water when water is shut down.) (Malfunction device, instantaneous water heater, etc.)
日本においては、水道施設の普及率が高く、火災の発生している多くは住宅や雑居ビルに集中し被害者の多くは高齢者や弱者となっている。大型施設には消火設備は設置されているものの小規模建築物には設置が無いのが実状で、老人ホームやデイサービスホームなどの小型施設に消火設備が設置され始めた。安価に広く普及が進めば火災事故は少なく成り、より多くの設備形態が市販される事で社会ニーズも高まる。災害発生時、特に地震災害では出火件数が人命に大きく関わり、住宅や雑居ビル以外に工場などにも簡易設備として設置が可能となる事から産業上の利用価値は大きい。また、貯水構造は飲用水に対応しているので防災の観点からも意味合いは大きいと考える。 In Japan, the penetration rate of water supply facilities is high. Many fires are concentrated in houses and occupying buildings, and many victims are elderly and vulnerable. Large facilities have fire extinguishing equipment but small buildings do not. In fact, fire extinguishing equipment has begun to be installed in small facilities such as nursing homes and day service homes. If widespread use at low cost, fire accidents will be reduced, and social needs will increase as more equipment forms are marketed. In the event of a disaster, especially in the case of an earthquake disaster, the number of fires is greatly related to human life, and since it can be installed as a simple facility in factories as well as houses and occupying buildings, the industrial utility value is great. In addition, since the water storage structure is compatible with drinking water, the meaning is significant from the viewpoint of disaster prevention.
