Description
この発明は、消火装置に関する。 The present invention relates to a fire extinguishing apparatus.
消火装置の一例として、筐体内に加圧用ガスボンベと消火剤充填容器と消火用ホースとを備えたパッケージ消火装置が知られている（例えば、特許文献１参照）。 As an example of a fire extinguishing apparatus, a package fire extinguishing apparatus including a pressurizing gas cylinder, a fire extinguishing agent filling container, and a fire extinguishing hose is known (for example, see Patent Document 1).
加圧用ガスボンベの二次側には、加圧用ガスボンベから放出される加圧ガスの圧力（例えば、１５ＭＰａ）を所定の圧力値の圧力（例えば、１ＭＰａ）に調整する圧力調整器が設けられ、圧力調整器の二次側には消火剤充填容器が接続され、消火剤充填容器は消火用ホースに接続される。 A pressure regulator is provided on the secondary side of the pressurizing gas cylinder to adjust the pressure of the pressurized gas discharged from the pressurizing gas cylinder (for example, 15 MPa) to a predetermined pressure value (for example, 1 MPa). A fire extinguisher filling container is connected to the secondary side of the regulator, and the fire extinguisher filling container is connected to a fire hose.
火災時、操作者は、加圧用ガスボンベの起動バルブを開く。すると、加圧用ガスボンベから放出された加圧ガスは圧力調整器によって調圧されて消火剤充填容器に導入され、消火剤充填容器から消火剤が放出される。この消火剤は、消火用ホースに導入され、先端に設けられた消火用ノズルから噴射されるので、操作者は、火災を消火することができる。 In the event of a fire, the operator opens the start valve of the pressurized gas cylinder. Then, the pressurized gas released from the pressurizing gas cylinder is regulated by the pressure regulator and introduced into the extinguishing agent filling container, and the extinguishing agent is released from the extinguishing agent filling container. Since this extinguishing agent is introduced into the extinguishing hose and sprayed from the extinguishing nozzle provided at the tip, the operator can extinguish the fire.
また、パッケージ消火装置には、通常時の温度変動等の影響に基づく、消火剤充填容器内の昇圧により、消火剤が消火剤充填容器内から消火用ホースなどの外部に放出されないようにするため、昇圧防止用の逃がし弁が設けられている。逃がし弁は、圧力調整器によって調整された圧力よりも低い圧力（例えば、０．０３ＭＰａ）を境に、弁開口としての排出孔が開閉することにより、通常時の昇圧を防止するとともに、火災時（消火剤放出時）における消火剤充填容器内の昇圧を保持して、消火用ホースを介して、消火剤を消火用ノズルから噴射させることができる。この逃がし弁は、通常、消火剤充填容器の消火剤放出口に設けられる。 In addition, the package fire extinguishing device is designed to prevent the extinguishing agent from being released from the inside of the extinguishing agent filling container to the outside such as the extinguishing hose due to the pressure increase in the extinguishing agent filling container based on the influence of temperature fluctuations during normal times. A relief valve for preventing pressure increase is provided. The relief valve opens and closes a discharge hole as a valve opening at a pressure lower than the pressure adjusted by the pressure regulator (for example, 0.03 MPa), thereby preventing normal pressure increase and during a fire. The fire extinguisher can be injected from the fire extinguishing nozzle through the fire extinguishing hose while maintaining the pressure increase in the fire extinguisher filling container (when the extinguishing agent is discharged). This relief valve is normally provided at the extinguishing agent discharge port of the extinguishing agent filling container.
パッケージ消火装置は、火災時に装置が機能することを確認するため、定期的に機能点検を行う必要がある。点検内容としては、圧力調整器によって調圧される圧力値が適正であるかということ、昇圧防止用の逃がし弁が適正な圧力値で開閉するかということである。 Package fire extinguishing equipment needs to be regularly inspected to ensure that it functions in the event of a fire. The contents of inspection are whether the pressure value regulated by the pressure regulator is appropriate, and whether the relief valve for preventing pressure increase opens and closes at an appropriate pressure value.
しかし、従来、これらの機能点検を行うためには、圧力調整器、逃がし弁のそれぞれを装置から取り外し、機能点検を行わなければならなかった。 However, conventionally, in order to perform these function checks, it has been necessary to remove the pressure regulator and the relief valve from the apparatus and perform the function check.
この発明は、圧力調整器や逃がし弁などを装置から取り外すことなく、消火装置の機能点検を行えるようにすることを目的とする。 An object of the present invention is to make it possible to check the function of a fire extinguishing device without removing a pressure regulator, a relief valve, or the like from the device.

実施の形態１
以下、本発明の一実施の形態について説明する。消火装置の一例としてのパッケージ型消火装置は、前面に開口１ａを有する箱状の本体１と、本体１の開口１ａを開閉自在に覆う観音開き状の開閉扉２とから筐体が構成される。
Embodiment 1
Hereinafter, an embodiment of the present invention will be described. A package-type fire extinguisher as an example of a fire extinguisher includes a box-shaped main body 1 having an opening 1a on the front surface and a double door opening / closing door 2 that covers the opening 1a of the main body 1 so as to be freely opened and closed.
筐体内には、加圧用ガスボンベ７、圧力調整器９、消火剤充填容器３、消火用ホース４、消火用ノズル５が設けられている。 A pressurization gas cylinder 7, a pressure regulator 9, a fire extinguisher filling container 3, a fire hose 4 and a fire extinguishing nozzle 5 are provided in the housing.
加圧用ガスボンベ７は、例えば１５ＭＰａの圧力値の加圧ガスを充填したタンクで、常時閉の手動の起動バルブ７ａを開操作することにより、加圧ガスが放出される。 The pressurization gas cylinder 7 is a tank filled with a pressurization gas having a pressure value of, for example, 15 MPa, and the pressurization gas is released by opening a normally closed manual start valve 7a.
圧力調整器９は、加圧用ガスボンベ７の二次側に接続され、加圧用ガスボンベ７から放出された加圧ガスの圧力を第一の圧力値の圧力（例えば、１ＭＰａ） に調整して、その二次側から放出する。 The pressure regulator 9 is connected to the secondary side of the pressurization gas cylinder 7 and adjusts the pressure of the pressurization gas released from the pressurization gas cylinder 7 to a pressure of a first pressure value (for example, 1 MPa). Release from the secondary side.
消火剤充填容器３は消火剤としての泡消火薬剤を充填したタンクであり、この実施の形態では２つ設けられている。消火剤充填容器３は、加圧ガス導入管１０を介して、加圧ガスを消火剤充填容器３内に導入し、この加圧作用により、泡消火薬剤が放出集合管１１に放出される。 The extinguishing agent filling container 3 is a tank filled with a foam extinguishing agent as an extinguishing agent, and two tanks are provided in this embodiment. The extinguishing agent filling container 3 introduces the pressurized gas into the extinguishing agent filling container 3 through the pressurized gas introduction pipe 10, and the foam extinguishing agent is released into the discharge collecting pipe 11 by this pressurizing action.
消火用ホース４は保形性能を有する、例えば長さ方向に垂直な断面が中空円形状のゴムホースである。消火用ホース４は、基端が放出集合管１１を介して消火剤充填容器３と接続され、先端に消火用ノズル５が設けられる。消火用ホース４は、放出集合管１１を介して、各消火剤充填容器３から放出された泡消火薬剤を消火用ホース４に導入する。 The fire-extinguishing hose 4 is a rubber hose having a shape retaining performance, for example, a cross section perpendicular to the length direction having a hollow circular shape. The extinguishing hose 4 is connected at its proximal end to the extinguishing agent filling container 3 through the discharge collecting pipe 11, and the extinguishing nozzle 5 is provided at the distal end. The fire-extinguishing hose 4 introduces the foam fire-extinguishing agent released from each fire-extinguishing agent-filled container 3 into the fire-extinguishing hose 4 via the discharge collecting pipe 11.
消火用ホース４は、基端側を筐体下部方向に立ち下げてから、筐体外周側を迂回して筐体上部方向に立ちあげられて、筐体上部に設けられたホース収納部６内部に導入され、ホース収納部６の内壁に沿って、巻き回して収納される。 The fire-extinguishing hose 4 is lowered from the base end toward the lower part of the casing, and is then raised around the outer periphery of the casing toward the upper part of the casing. And is wound and stored along the inner wall of the hose storage portion 6.
消火用ノズル５は、消火用ノズル５から泡消火薬剤により生成される消火用泡(消火液)を放出するために操作される常時は閉の手動のレバー５ａを有する。消火用ノズル５は、発泡倍率が例えば５〜２０と低い消火用泡(低発泡)を生成して放出する低発泡用放水部５ｂと、発泡倍率が例えば２０〜８０と比較的高い消火用泡(中発泡)を生成して放出する中発泡用放水部５ｃとを備えている。 The fire-extinguishing nozzle 5 has a normally closed manual lever 5a that is operated to release fire-extinguishing foam (extinguishing liquid) generated by the foam fire-extinguishing agent from the fire-extinguishing nozzle 5. The fire-extinguishing nozzle 5 includes a low-foaming water discharge portion 5b that generates and discharges a low-foaming foam (low foaming) of 5 to 20, for example, and a relatively high foaming ratio of 20 to 80, for example. And a middle foaming water discharge part 5c that generates and discharges (medium foaming).
圧力調整器９と消火剤充填容器３（加圧ガス導入管１０）との間には、仕切弁２０、昇圧防止用の逃がし弁３０、パージ弁４０が設けられている。加圧ガス導入管１０の基端に仕切弁２０が接続され、仕切弁２０の一次側に逃がし弁３０が接続され、逃がし弁３０の一次側にパージ弁４０が接続され、パージ弁４０の一次側に圧力調整器９の二次側が接続される。なお、逃がし弁３０とパージ弁４０とは、その配設位置を逆としてもよい。 Between the pressure regulator 9 and the extinguishing agent filling container 3 (pressurized gas introduction pipe 10), a gate valve 20, a pressure increase preventing relief valve 30, and a purge valve 40 are provided. A gate valve 20 is connected to the proximal end of the pressurized gas introduction pipe 10, a relief valve 30 is connected to the primary side of the gate valve 20, a purge valve 40 is connected to the primary side of the relief valve 30, and the primary of the purge valve 40. The secondary side of the pressure regulator 9 is connected to the side. Note that the relief valve 30 and the purge valve 40 may have their arrangement positions reversed.
仕切弁２０は、手動の例えば、ボールバルブであり、常時は開で、圧力調整器９から消火剤充填容器３までの間の流路を遮断しないで、加圧ガス導入管１０を介して、圧力調整器９からの加圧ガスを消火剤充填容器３に導入させる。一方、点検時は閉に操作されて、圧力調整器９と消火剤充填容器３との間の流路を遮断して、加圧ガス導入管１０を介して、圧力調整器９からの加圧ガスを消火剤充填容器３に導入させない。 The gate valve 20 is a manually operated ball valve, for example, which is normally open and does not block the flow path from the pressure regulator 9 to the fire extinguisher filling container 3 via the pressurized gas introduction pipe 10. The pressurized gas from the pressure regulator 9 is introduced into the fire extinguisher filling container 3. On the other hand, it is closed during inspection, shuts off the flow path between the pressure regulator 9 and the extinguishing agent filling container 3, and pressurizes from the pressure regulator 9 via the pressurized gas introduction pipe 10. The gas is not introduced into the extinguishing agent filling container 3.
逃がし弁３０は、Ｔ字管としての配管部３１と、本体３３とを有する。配管部３１は、加圧ガスの通過経路に直交して開口部３１ａを有する分岐管３１ｂが設けられ、分岐管３１ｂにＯリング３２を介して本体３３が螺着される。 The relief valve 30 has a piping part 31 as a T-shaped pipe and a main body 33. The piping part 31 is provided with a branch pipe 31b having an opening 31a orthogonal to the passage path of the pressurized gas, and a main body 33 is screwed to the branch pipe 31b via an O-ring 32.
本体３３は、内部を貫通するように、ボール収納部３４、スプリング収納部３５、排出孔３６が連続して設けられる。これらの内径は、ボール収納部３４、スプリング収納部３５、排出孔３６の順で小さい。 The main body 33 is continuously provided with a ball storage portion 34, a spring storage portion 35, and a discharge hole 36 so as to penetrate the inside. These inner diameters are smaller in the order of the ball storage portion 34, the spring storage portion 35, and the discharge hole 36.
ボール収納部３４は、ボール３７が摺動自在に内部に収納される。ボール３７の外径は、ボール収納部３４の内径よりも小さく、かつスプリング収納部３５の内径よりも大きい。ボール収納部３４は、開口部３１ａに面する一端側が複数の連通孔３８ａを有するボール押え板３８で閉止され、他端側は、スプリング収納部３５とほぼ同径の内径を有するパッキン３９が設けられる。 The ball storage portion 34 stores a ball 37 slidably therein. The outer diameter of the ball 37 is smaller than the inner diameter of the ball storage portion 34 and larger than the inner diameter of the spring storage portion 35. The ball storage portion 34 is closed at one end facing the opening 31a by a ball press plate 38 having a plurality of communication holes 38a, and a packing 39 having an inner diameter substantially the same as that of the spring storage portion 35 is provided at the other end. It is done.
スプリング収納部３５は、スプリング収納部３５とほぼ同径の、例えばコイル状のスプリング３５ａが収納される。スプリング３５ａは、ボール３７に当接して、ボール押え板３８方向にボール３７を付勢する。 The spring storage portion 35 stores, for example, a coiled spring 35a having substantially the same diameter as the spring storage portion 35. The spring 35 a abuts on the ball 37 and urges the ball 37 toward the ball pressing plate 38.
ボール３７は、スプリング３５ａの付勢力により、常時は、ボール押え板３８に当接している。この状態のときは、ボール３７の外径がボール収納部３４の内径よりも小さいため、配管部３１内の加圧ガスなどの流体は、開口部３１ａ、連通孔３８ａ、ボール３７とボール収納部３４との隙間、スプリング収納部３５を介して、排出孔３６から外部に排出される。 The ball 37 is always in contact with the ball pressing plate 38 by the urging force of the spring 35a. In this state, since the outer diameter of the ball 37 is smaller than the inner diameter of the ball storage portion 34, the fluid such as the pressurized gas in the piping portion 31 is free from the opening 31 a, the communication hole 38 a, the ball 37 and the ball storage portion. 34 is discharged to the outside through the discharge hole 36 via the gap 34 and the spring storage portion 35.
一方、第二の圧力値としての例えば、０．０３ＭＰａ以上の反力がボール３７に生じると、スプリング３５ａが縮んで、ボール３７がパッキン３９に当接する。この状態のときは、配管部３１内の加圧ガスなどの流体は、ボール収納部３４とスプリング収納部３５との連通をボール３７が閉止するので、排出孔３６から外部に排出されない。 On the other hand, for example, when a reaction force of 0.03 MPa or more as the second pressure value is generated in the ball 37, the spring 35 a contracts and the ball 37 contacts the packing 39. In this state, fluid such as pressurized gas in the pipe portion 31 is not discharged to the outside through the discharge hole 36 because the ball 37 closes the communication between the ball storage portion 34 and the spring storage portion 35.
上記の構成により、逃がし弁３０は、第一の圧力値（例えば、１ＭＰａ）よりも低い第二の圧力値（例えば、０，０３ＭＰａ）未満の圧力では開放して、消火剤充填容器３内の平常時の昇圧を防止し、また、第二の圧力値（例えば、０，０３ＭＰａ）以上の圧力では閉鎖して、圧力調整器９から導入される加圧ガスによる消火剤充填容器３の昇圧を保持することができる。 With the above configuration, the relief valve 30 is opened at a pressure lower than the first pressure value (for example, 1 MPa) and lower than the second pressure value (for example, 0.03 MPa), so that the inside of the fire extinguisher-filled container 3 is opened. The normal pressure increase is prevented, and the pressure of the extinguishing agent filling container 3 is increased by the pressurized gas introduced from the pressure regulator 9 by closing at a pressure equal to or higher than the second pressure value (for example, 0.03 MPa). Can be held.
つぎに、パージ弁４０は、配管部４１と、キャップ４２とを有する。配管部４１は、加圧ガスの通過経路に直交して開口部４１ａを有する分岐部４１ｂが設けられ、分岐部４１ｂにキャップ４２が螺着される。 Next, the purge valve 40 includes a piping part 41 and a cap 42. The piping part 41 is provided with a branch part 41b having an opening part 41a orthogonal to the passage path of the pressurized gas, and a cap 42 is screwed to the branch part 41b.
キャップ４２は押圧穴４３が設けられ、押圧穴４３内に押釦４４が配置される。開口部４１ａと押釦４４との間には、押釦４４を押圧穴４３側に付勢するスプリング４５が設けられる。 The cap 42 is provided with a pressing hole 43, and a push button 44 is disposed in the pressing hole 43. A spring 45 is provided between the opening 41a and the push button 44 to urge the push button 44 toward the push hole 43 side.
押釦４４は、スプリング４５の付勢力により、常時は、押圧穴４３に当接している。この状態のときは、配管部４１内の加圧ガスなどの流体は、押圧穴４３から外部に排出されることはない。 The push button 44 is always in contact with the pressing hole 43 by the biasing force of the spring 45. In this state, fluid such as pressurized gas in the piping part 41 is not discharged from the pressing hole 43 to the outside.
一方、操作者により、押釦４４が押し操作されると、スプリング４５が縮んで、押釦４４と押圧穴４３との間に隙間が生じるため、配管部４１内の加圧ガスなどの流体は、開口部４１ａ、押釦４４と押圧穴４３との間の隙間を介して、押圧穴４３から外部に排出される。 On the other hand, when the operator pushes the push button 44, the spring 45 contracts and a gap is formed between the push button 44 and the push hole 43, so that fluid such as pressurized gas in the pipe portion 41 is opened. It is discharged from the pressing hole 43 to the outside through a gap between the portion 41 a, the push button 44 and the pressing hole 43.
上記の構成により、パージ弁４０は、点検時等に操作されることにより、圧力調整器９と仕切弁２０との間の流路の圧力をパージすることができる。なお、押釦４４と押圧穴４３との間に、Ｏリング等を配設して気密性を向上させることもできる。また、パージ弁４０は、キャップ４２の代わりに、分岐部４１ｂに常時は閉の手動のボールバルブを螺着する構造としてもよい。 With the above configuration, the purge valve 40 can be purged of the pressure in the flow path between the pressure regulator 9 and the gate valve 20 by being operated at the time of inspection or the like. In addition, an O-ring or the like can be provided between the push button 44 and the press hole 43 to improve the airtightness. Further, the purge valve 40 may have a structure in which a normally closed manual ball valve is screwed to the branch portion 41 b instead of the cap 42.
つぎに、本実施の形態のパッケージ型消火装置の動作について説明する。まず、通常時、レバー５ａは閉、起動バルブ７ａは閉、仕切弁２０は開である。この状態において、環境温度の変動に基づいて、消火剤充填容器３内に微小の昇圧（０．０３ＭＰａ未満）が生じた場合、逃がし弁３０の排出孔３６がボール３７により塞がれていないので、昇圧分の圧力は、加圧ガス導入管１０を経由して、逃がし弁３０の排出孔３６から外部に放出されるため、消火剤充填容器３内は通常時の大気圧に維持することができる。これにより、消火剤充填容器３内の泡消火薬剤が、消火用ホース４などの外部に放出されることがなくなる。 Next, the operation of the package fire extinguisher of the present embodiment will be described. First, at the normal time, the lever 5a is closed, the start valve 7a is closed, and the gate valve 20 is opened. In this state, when a minute pressure increase (less than 0.03 MPa) occurs in the fire extinguisher filling container 3 based on the fluctuation of the environmental temperature, the discharge hole 36 of the relief valve 30 is not blocked by the ball 37. The pressure of the increased pressure is discharged to the outside through the pressurized gas introduction pipe 10 and from the discharge hole 36 of the relief valve 30, so that the inside of the fire extinguisher filling container 3 can be maintained at the normal atmospheric pressure. it can. Thereby, the foam extinguishing agent in the extinguishing agent filling container 3 is not released to the outside such as the extinguishing hose 4.
火災が発生した場合、操作者はまず、開閉扉２を開けて起動バルブ７ａを開く。すると加圧用ガスボンベ７からの加圧ガスが圧力調整器９で第１の圧力値（例えば、１ＭＰａ）の圧力に調整されて、加圧ガス導入管１０を介して各消火剤充填容器３内に導入される。そして、各消火剤充填容器３内の泡消火薬剤が放出集合管１１を介して消火用ホース４に導入される。このとき、逃がし弁３０は、ボール３７がパッキン３９に着座して排出孔３６からの圧力漏れが生じないので、圧力調整器９から導入される加圧ガスによる消火剤充填容器３の昇圧を保持することができる。つぎに、操作者は、消火用ノズル５を手に持って消火用ホース４をホース収納部６から引き出し、火災発生場所へと近づく。そして操作者は、最初に少し離れた場所から、レバー５ａを操作して、低発泡用放水部５ｂから消火用泡(低発泡)を放出する。そしてある程度、火勢が鎮まったら、火災発生場所に近づいて、レバー５ａを操作して中発泡用放水部５ｃから消火用泡(中発泡)を放出して、火災を鎮火する。火災鎮火後、操作者は、起動バルブ７ａ、レバー５ａを閉じ、消火用ホース４をホース収納部６内に収納する。 When a fire occurs, the operator first opens the opening / closing door 2 and opens the start valve 7a. Then, the pressurized gas from the pressurizing gas cylinder 7 is adjusted to a pressure of a first pressure value (for example, 1 MPa) by the pressure regulator 9 and is put into each extinguisher filling container 3 through the pressurized gas introduction pipe 10. be introduced. Then, the foam extinguishing agent in each extinguishing agent filling container 3 is introduced into the extinguishing hose 4 through the discharge collecting pipe 11. At this time, since the ball 37 is seated on the packing 39 and the pressure leakage from the discharge hole 36 does not occur, the relief valve 30 maintains the pressure increase of the extinguisher filling container 3 by the pressurized gas introduced from the pressure regulator 9. can do. Next, the operator holds the fire-extinguishing nozzle 5 in his / her hand and pulls out the fire-extinguishing hose 4 from the hose storage portion 6 and approaches the fire occurrence place. Then, the operator operates the lever 5a from a location a little away from the beginning, and discharges the fire-extinguishing foam (low foaming) from the low foaming water discharge part 5b. When the fire is moderated to some extent, the fire is approached and the fire is extinguished by operating the lever 5a to release the fire-extinguishing foam (medium foam) from the middle foaming water discharge part 5c. After the fire is extinguished, the operator closes the start valve 7 a and the lever 5 a and stores the fire hose 4 in the hose storage 6.
点検時には、操作者は、まず常時開の仕切弁２０を閉じる。つぎに、逃がし弁３０の機能点検を行うために、常時閉の起動バルブ７ａをほんの少しだけ開いて、第二の圧力値（例えば、０．０３ＭＰａ）未満の圧力値の圧力の加圧ガスを仕切弁２０までの経路に導入させる。このとき、逃がし弁３０が正常であれば、逃がし弁３０の排出孔３６が閉止していないので、排出孔３６から加圧ガスがリークする。操作者は、この排出音を確認して、正常と判断する。また、排出孔３６周りに石鹸水などを付着させ、泡立つことで正常と判断してもよい。 At the time of inspection, the operator first closes the normally open gate valve 20. Next, in order to check the function of the relief valve 30, the normally closed start valve 7a is opened only slightly, and a pressurized gas having a pressure value less than the second pressure value (for example, 0.03 MPa) is supplied. It is introduced into the route to the gate valve 20. At this time, if the relief valve 30 is normal, the discharge hole 36 of the relief valve 30 is not closed, and the pressurized gas leaks from the discharge hole 36. The operator confirms this discharged sound and determines that it is normal. Moreover, you may judge that it is normal by making soap water etc. adhere around the discharge hole 36, and foaming.
つぎに、起動バルブ７ａをさらに開いて圧力調整器９によって調整される第一の圧力値（例えば、１ＭＰａ）の圧力の加圧ガスを仕切弁２０までの経路に導入させる。このとき、逃がし弁３０が正常であれば、逃がし弁３０の排出孔３６が閉止しているので、排出孔３６から加圧ガスがリークしない。操作者は、この排出音がないことを確認して、正常と判断する。また、排出孔３６周りに石鹸水などを付着させ、泡立たないことで正常と判断してもよい。なお、逃がし弁３０が異常ならば交換する。このように、昇圧防止用の逃がし弁３０が適正な圧力値で開閉するかを確認することができる。 Next, the starting valve 7 a is further opened, and a pressurized gas having a first pressure value (for example, 1 MPa) adjusted by the pressure regulator 9 is introduced into the path to the gate valve 20. At this time, if the relief valve 30 is normal, the discharge hole 36 of the relief valve 30 is closed, so that the pressurized gas does not leak from the discharge hole 36. The operator confirms that there is no discharge sound and determines that the sound is normal. Further, normality may be determined by adhering soap water or the like around the discharge hole 36 so as not to foam. If the relief valve 30 is abnormal, replace it. In this way, it can be confirmed whether the relief valve 30 for preventing pressure increase opens or closes at an appropriate pressure value.
またこのとき、圧力調整器９の二次側圧力ゲージ９ａを目視することによって、圧力調整器９によって調整される第一の圧力値（例えば、１ＭＰａ）が適正値であるかを確認することができる。適正値でなければ、圧力調整ツマミ９ｂを操作して、二次側圧力ゲージ９ａを目視しながら、第一の圧力値を適正値にする。以上のように、圧力調整器９、逃がし弁３０のそれぞれを装置から取り外すことなく、消火装置の機能点検を行えることができる。 At this time, it is possible to confirm whether or not the first pressure value (for example, 1 MPa) adjusted by the pressure regulator 9 is an appropriate value by visually observing the secondary pressure gauge 9a of the pressure regulator 9. it can. If it is not an appropriate value, the first pressure value is set to an appropriate value by operating the pressure adjustment knob 9b while visually observing the secondary pressure gauge 9a. As described above, the function check of the fire extinguishing device can be performed without removing each of the pressure regulator 9 and the relief valve 30 from the device.
機能点検終了後は、操作者は、起動バルブ２０を閉じ、つぎにパージ弁４０の押釦４４を押圧操作して、圧力調整器９と仕切弁２０との間の流路の圧力をパージする。最後に、仕切弁２０を開くことによって、装置を通常状態に復帰させる。 After the function check is completed, the operator closes the start valve 20 and then presses the push button 44 of the purge valve 40 to purge the pressure in the flow path between the pressure regulator 9 and the gate valve 20. Finally, the device is returned to the normal state by opening the gate valve 20.
以上の通り、本実施の形態の消火装置としてのパッケージ型消火装置は、常時は閉の手動の起動バルブ７ａが開放されることによって、内部に充填された加圧ガスを放出する加圧用ガスボンベ７と、加圧用ガスボンベ７に接続され、加圧用ガスボンベ７から放出される加圧ガスの圧力を第一の圧力値（例えば、１ＭＰａ）に調整する圧力調整器９と、該圧力調整器９に接続され、該圧力調整器９によって調整された第一の圧力値の圧力の加圧ガスが導入されることによって、内部に充填された消火剤（泡消火薬剤）を放出する消火剤充填容器３と、該消火剤充填容器３に基端が接続され、消火剤充填容器３から放出される消火剤が供給されて、先端に設けられた消火用ノズル５から消火剤を噴射する消火用ホース４と、第一の圧力値よりも低い第二の圧力値（例えば、０．０３ＭＰａ）未満の圧力では開放して、消火剤充填容器３内の平常時の昇圧を防止し、また、第二の圧力値以上の圧力では閉鎖して、圧力調整器９から導入される加圧ガスによる消火剤充填容器３の昇圧を保持する逃がし弁３０と、を備えた消火装置において、圧力調整器９と消火剤充填容器３との間に、常時は開で点検時に閉に操作されて、圧力調整器９と消火剤充填容器３との間の流路を遮断する、手動の仕切弁２０を設け、圧力調整器９と仕切弁２０との間に、逃がし弁３０を設けるようにしたので、圧力調整器９、逃がし弁３０のそれぞれを装置から取り外すことなく、消火装置の機能点検を行えることができる。 As described above, the package-type fire extinguisher as the fire extinguisher of the present embodiment is a pressurized gas cylinder 7 that discharges the pressurized gas filled therein by opening the normally closed manual activation valve 7a.

In addition, since the relief valve 30 is provided, it is possible to check the function of the fire extinguishing device without removing the pressure regulator 9 and the relief valve 30 from the device.
また、圧力調整器９と仕切弁２０との間に、点検時に、圧力調整器９と仕切弁２０との間の流路の圧力をパージする手動のパージ弁４０を備えるようにしたので、機能点検終了後は、操作者は、装置を通常状態に復帰させることができる。 Further, since a manual purge valve 40 for purging the pressure in the flow path between the pressure regulator 9 and the gate valve 20 is provided between the pressure regulator 9 and the gate valve 20 at the time of inspection. After the inspection is completed, the operator can return the apparatus to the normal state.
また、本実施の形態の消火装置としてのパッケージ型消火装置は、常時は閉の手動の起動バルブ７ａが開放されることによって、内部に充填された加圧ガスを放出する加圧用ガスボンベ７と、加圧用ガスボンベ７に接続され、加圧用ガスボンベ７から放出される加圧ガスの圧力を第一の圧力値（例えば、１ＭＰａ）に調整する圧力調整器９と、該圧力調整器９に接続され、該圧力調整器９によって調整された第一の圧力値の圧力の加圧ガスが導入されることによって、内部に充填された消火剤（泡消火薬剤）を放出する消火剤充填容器３と、該消火剤充填容器３に基端が接続され、消火剤充填容器３から放出される消火剤が供給されて、先端に設けられた消火用ノズル５から消火剤を噴射する消火用ホース４と、を備えた消火装置において、圧力調整器９と消火剤充填容器３との間に、常時は開で点検時に閉に操作されて、圧力調整器９と消火剤充填容器３との間の流路を遮断する、手動の仕切弁２０を設け、圧力調整器９と仕切弁２０との間に、点検時に、圧力調整器９と仕切弁２０との間の流路の圧力をパージする手動のパージ弁４０を備えるようにしたので、圧力調整器９を装置から取り外すことなく、機能点検を行えることができる。そして、機能点検終了後は、操作者は、装置を通常状態に復帰させることができる。この場合、圧力調整器９を装置から取り外すことなく、圧力調整器９の機能点検を行えることができればよく、逃がし弁３０は、本実施の形態のように、圧力調整器９と仕切弁２０との間に設けることに限定されない。 The package-type fire extinguisher as the fire extinguisher of the present embodiment is a pressurized gas cylinder 7 that releases a pressurized gas filled therein by opening a normally closed manual activation valve 7a; A pressure regulator 9 connected to the pressurization gas cylinder 7 and adjusting the pressure of the pressurization gas discharged from the pressurization gas cylinder 7 to a first pressure value (for example, 1 MPa), and connected to the pressure regulator 9; A fire extinguisher filling container 3 for releasing a fire extinguishing agent (foam extinguishing agent) filled therein by introducing a pressurized gas having a pressure of a first pressure adjusted by the pressure regulator 9; A fire extinguishing hose 4 having a proximal end connected to the fire extinguisher filling container 3, supplied with a fire extinguishing agent discharged from the fire extinguishing agent filling container 3, and injecting a fire extinguishing agent from a fire extinguishing nozzle 5 provided at the tip; In the fire extinguishing device provided, A manual partition between the force regulator 9 and the extinguishing agent filling container 3 that is normally opened and closed during inspection to shut off the flow path between the pressure regulator 9 and the extinguishing agent filling container 3.
