【発明の詳細な説明】 爆発製吹付は装置 技術分野 本発明は火炎によるコーティングに係り、より具体的には爆発製吹付は装置に関 する。[Detailed description of the invention] Explosive spraying device Technical field This invention relates to flame coating and more specifically to explosive spraying equipment. do.
背景技術 気体燃料たとえばアセチレンガスと酸素とを用いる爆発製吹付は装置の安全上の 問題は、爆発製吹付は法を実施する場合、特に爆発吹付は装置が爆発吹付は作業 用に特別に作られていない建屋の中に設置される場合に生ずる。Background technology Explosive spraying using gaseous fuels, such as acetylene gas and oxygen, is a safety concern for the equipment. The problem is when enforcing the Explosive Spray Act, especially when the Explosive Spray equipment is Occurs when installed in a building not specially constructed for the purpose.
従来公知の爆発製吹付は装置（Ｓ、Ｓ、パルチック（Ｓ、Ｓ、Ｂａｒｔｅｎｏｖ ） 、Ｙ ｕ 、 Ｐ 、フェト：１（Ｙ（１，Ｐ。Conventionally known explosive spray devices (S, S, Paltic (S, S, Bartenov) ), Y u, P, Feto: 1 (Y(1, P.

Grigorov): Machinery Explosive flame coatings in engineering: 1982, Machinostroheny Publishing House (H aShinO3tr’0eniePublishers) (Leningrad branch) Published by Leringrad Subsidiary, pp. 118-119 ) contains the following devices: In other words, flame spraying is for explosives an explosive cylinder with a igniter and an igniter, a gas mixing device connected to the cylinder, and a gas mixing device connected to the cylinder; a fuel supply system connected to a gas mixing device and each having a device for changing the pressure; Gas supply system, inert gas supply system, control device, gas flow meter, and directly connected thereto. a main valve mounted in the column and normally closed, and the above fuel supply system and oxygen gas supply. a gas supply control device electrically connected to the normally closed main valve of the system; an explosive acoustically connected to the barrel and electrically connected to said gas supply control device; a control system electrically connected to the gas supply control device and ignition device; system and three types of gas supply source equipment installed outside the building where each of the above equipment is installed. and the first gas source device has a second gas source connected to the fuel source line. A device is connected to the oxygen supply line and a third gas supply device is connected to the inert gas supply line. Connected.
この従来の爆発製吹付は装置における重大な欠点は、上記ガス供給系統がゆるん だ場合に、上記燃料ガス供給源装置及び酸素供給源装置を迅速に切り離せないこ とにある。上記ガス供給源装置、特に燃料ガス供給系統（たとえばアセチレンガ ス供給源装置）にゆるみが生ずれば、上記建屋の中に空気と燃料ガスが大量に充 満し、爆発を起こし易い状態に混ざり合うので極めて危険であるから爆発製吹付 は用に作られていない建屋の中で上記爆発製吹付は装置を生産に使用できなくな る。A major drawback of this conventional explosive spraying device is that the gas supply system is loose. In such a case, the fuel gas supply source device and the oxygen supply source device cannot be quickly separated It's there. The above gas supply equipment, especially the fuel gas supply system (e.g. acetylene gas) If the fuel gas supply source equipment) becomes loose, a large amount of air and fuel gas will fill the above building. Explosive spraying is extremely dangerous as it can mix in a way that can easily cause an explosion. Explosive spraying in a building not designed for this purpose may render the equipment unusable for production. Ru.
そのうえ、上記ガス供給ラインの安全確保のために上記爆発製吹付は装置の弁は ガス混合装置の直ぐ上流側に設けられるが、この弁は爆発の衝撃の熱作用を受け 、この熱作用は特に上記燃料ガス（アセチレンガス）供給ラインの通常閉じられ る主弁を傷める。それ故、上記主弁は閉じられた時にゆるみを生ずることが許さ れない。もしゆるむようなことがあれば、火炎が上記ガス温合装置まで遡った場 合、又は上記点火装置が偶発的に作動した場合、すなわち上記爆発検知器が次の 爆発を検知せず上記ガスの供給を停止すべき時に上記通常閉じられる主弁を初期 位置に戻すための指令が明瞭に出されてもガスたとえばアセチレンガスの供給が 継続される。上記火炎が上記ガス混合装置まで遡ったために次の爆発の衝撃が生 じない場合にアセチレンガスの供給が継続されれば上記ガス混合装置が過熱され 、そのために上記火炎はさらに上記燃料ガス供給系統の中を遡る。アセチレンガ スは加熱されると自動的に分解するからである。もし点火装置の故障が原因で点 火装置に点火電流が流れない場合にアセチレンガスの供給が継続されれば、上記 爆発筒が設置されている建屋の中にアセチレンガスがたまり、爆発濃度になるの で、作業員の努力で上記燃料供給源装置を極めて迅速に切り離し得たとしても爆 発ガスがたまる危険がある。Moreover, in order to ensure the safety of the gas supply line, the valve of the device for the above explosive blowing is Located immediately upstream of the gas mixing device, this valve is subject to the thermal effects of the explosion shock. , this thermal effect is particularly important when the fuel gas (acetylene gas) supply line is normally closed. Damage to the main valve. Therefore, the above main valve is not allowed to loosen when closed. Not possible. If it loosens, the flame may trace back to the gas heating device mentioned above. or if said igniter is accidentally activated, i.e. if said explosion detector: Initializes the main valve, which is normally closed when no explosion is detected and the supply of the gas should be stopped. Even if the command to return to the position is clearly given, the supply of gas such as acetylene gas Continued. The flames traced back to the gas mixing device, causing the shock of the next explosion. If not, if the acetylene gas supply continues, the gas mixing device will overheat. Therefore, the flame further traces back into the fuel gas supply system. Acetylene brick This is because gas automatically decomposes when heated. If the ignition system malfunctions, the If the supply of acetylene gas is continued when the ignition current does not flow to the fire device, the above Acetylene gas accumulates in the building where the explosive tube is installed and reaches an explosive concentration. However, even if the fuel supply device could be disconnected extremely quickly through the efforts of the workers, it would not cause an explosion. There is a risk of gas buildup.
それ故、上記通常閉じられる主弁の信頼性が低く、特に燃料ガス供給ラインの主 弁の信頼性が悪い場合には、上記爆発製吹付は装置全体の安全性が低下する。Therefore, the reliability of the main valve, which is normally closed, is low, especially the main valve of the fuel gas supply line. If the valve is unreliable, the explosive blowout will reduce the safety of the entire system.
上記爆発炎吹付装置は客観的な管理、たとえばガス混合装置が正常に作動してい ることを定量的に点検することができない。ガス混合装置は、混合されるガスが 連続的に供給される場合には、周知の噴出型混合装置より成り、このガス混合装 置が正常な状態にあることは工程安定ト重要であるだけでなく、上記爆発製吹付 は装置全体の安全性にとっても極めて重要である。The above explosive flame spray equipment must be objectively controlled, for example, to ensure that the gas mixing equipment is operating normally. It is not possible to quantitatively check that Gas mixing equipment is used to In the case of continuous supply, this gas mixing device consists of a well-known jet-type mixing device. It is not only important for the equipment to be in normal condition to stabilize the process, but also to ensure that the is also extremely important for the safety of the entire device.
最後に、上記爆発製吹付は装置は、爆発製吹付は作業終了時、この装置を長期間 休止させる時、又は何等かの危険が存在する時（たとえば緊急事態すなわち爆発 の危険がある時）に、この装置の燃料ガス供給ラインを不活性ガスで満たすこと ができない。そのために、上記爆発製吹付は装置は、通常の施設の中で使用でき る範囲が、安全上の見地から制限されるという欠点を有する。Finally, the above explosive spraying equipment should be used for a long time when the explosive spraying work is finished. or when there is some danger (e.g. an emergency, i.e. an explosion). Fill the fuel gas supply line of this equipment with inert gas when there is a danger of I can't. Therefore, the above explosive spraying equipment cannot be used in normal facilities. It has the disadvantage that the range in which it can be used is limited from a safety standpoint.

本発明に基づく上記爆発炎吹付は装置はいくつかの作動モードを有する。すなわ ちこの作動モードは「ガス混合装置正常状態確認モード」、［アセチレン通気モ ード」、「吹付はモード」、［アセチレン掃気モード］、及び「緊急モード」で ある。The explosive flame blowing device according to the invention has several modes of operation. Sunawa Chiko's operating modes are "Gas mixing device normal status confirmation mode" and "Acetylene ventilation mode". mode,” “Acetylene scavenging mode,” and “Emergency mode.” be.
上記「ガス混合装置制御状態確認モード」は準備段階のモードであり、上記吹付 は作業開始前に上記噴出型のガス混合装置５の偶発的誤作動を検出するためのモ ードである。The above "gas mixing device control status confirmation mode" is a preparatory mode, and the above is a model for detecting accidental malfunction of the above-mentioned blowout type gas mixing device 5 before starting work. It is a code.
上記「アセチレン掃気モード」も準備のためのモードであり、上記１−ガス混合 装置正常状態確認モード」実施直後に行なわれる。このモードが必要な理由は、 工場によっては、ガス供給ライン、特にアセチレンライン６の規模が大ぎく、上 記ガス混合装置におけるアセチレンガスの圧力が比較的低い場合があるからであ る。The above "acetylene scavenging mode" is also a mode for preparation, and the above 1-gas mixture Immediately after executing "Device normal state confirmation mode". This mode is necessary because In some factories, the scale of the gas supply line, especially the acetylene line 6, is so large that the upper This is because the pressure of acetylene gas in the gas mixing device may be relatively low. Ru.
上記「吹付はモード」は基本的な作動モードであり、上記爆発炎吹付は法によっ てコーティングするためのものである。The above "spraying mode" is the basic operating mode, and the above explosive flame spraying is not permitted by law. It is used for coating.
上記「アセチレン掃気モード」は最終段階のモードであり、上記「吹付はモード 」の後で実施される。このモードは特に重要であり、所定の操業条件の下で長時 間（たとえば−晩中）、上記アセチレンライン６にアセチレンガスを通さない場 合、又はアセチレンガスを残留させることが許されない場合に使用される。The above "acetylene scavenging mode" is the final stage mode, and the above "spraying mode" is the final stage mode. ” will be carried out after. This mode is particularly important and can be used for long periods of time under given operating conditions. If the acetylene gas is not passed through the acetylene line 6 during the Used in cases where residual acetylene gas is not allowed.
上記「緊急モード」は、たとえば上記吹付はブースに爆発の危険がある場合、換 気装置が作動しない場合、上記吹付はブースの中で上記アセチレンライン、若し くは酸素ラインに破損、弛緩等が場合、その他の緊急事態が生じた場合に、自動 的に作動するか又は作業員の操作によって開始される。The above "emergency mode" can be used, for example, if the above spraying is at risk of explosion in the booth, If the acetylene device does not work, the acetylene line or or if the oxygen line is damaged or loosened, or in the event of any other emergency. automatically activated or initiated by operator operation.
上記爆発炎吹付は装置は次のように作用する。The above explosive flame spraying device operates as follows.
上記アセチ１ノンガス供給源装置１０を開く前に窒素ガス供給源装置１１及び酸 素ガス供給瞭装置１２を開いて、アセチレンライン、窒素ライン、及び酸素ライ ンを所定の圧力にする。Before opening the acetylene 1 non-gas supply source device 10, the nitrogen gas supply source device 11 and the acid Open the elementary gas supply device 12 and connect the acetylene line, nitrogen line, and oxygen line. to the specified pressure.
次に上記制御システム４０を用いて上記［ガス混合５Ａ装正常作動状態確認モー ド」にする。このモードで上記ガス供給制御装置３９と接点３４乃至３８との電 気的接続が断たれる。これと同時に上記酸素ライン８の通常閉じられる補助弁２ ７及び主弁３２と、上記アセチレンライン６の通常閉じらる主弁１９を開く。上 記アセチレンライン６０通常閉じられる補助弁１３は最初から閉じたままにして おく。次に酸素ガス供給源装置１２から酸素ライン８に酸素を流すために補助弁 ２７及び減圧弁２８を間き、制御弁２９及び流量計３０を全開にし、弁３２を開 き、逆止弁３３をガス混合装置５に接続し、点火室３経由で爆発筒１に接続する 。点火栓４はこのモードではまだ作動しない。作業員は減圧弁２８を操作して酸 素ガスの圧力を圧力削３１の点検に必要な値に調節し、流量計３０を見ながら弁 ２９を操作して酸素の流量を調節する。酸素を噴出させると、この酸素が搬送流 体となって上記アセチレンライン６の閉じである弁１３から下流側が減圧される 。この減圧は正常作動状態で、たとえばガス混・合装置５で−０，５に９／ｃｒ Ａ乃至−０，４Ｋｇ／ｃｉであり、この減圧値は圧力計１８に示される。この減 圧値が許容範囲内にあれば上記ガス混合装置は正常作動状態にあり、吹付は作動 可能の状態にある。上記減圧を行なわず、又はこの減圧が適切でない場合には、 安全確保のために吹付けができない。Next, using the control system 40, the [gas mixing 5A equipment normal operation state confirmation mode] Change it to "C". In this mode, the electricity between the gas supply control device 39 and the contacts 34 to 38 is The emotional connection is severed. At the same time, the auxiliary valve 2 of the oxygen line 8 is normally closed. 7 and the main valve 32, and the normally closed main valve 19 of the acetylene line 6 are opened. Up The acetylene line 60 is normally closed, but the auxiliary valve 13 is kept closed from the beginning. put. Next, an auxiliary valve is used to flow oxygen from the oxygen gas supply source device 12 to the oxygen line 8. 27 and pressure reducing valve 28, fully open the control valve 29 and flow meter 30, and open the valve 32. , connect the check valve 33 to the gas mixing device 5, and connect it to the explosion tube 1 via the ignition chamber 3. . Spark plug 4 is not yet activated in this mode. The worker operates the pressure reducing valve 28 to release the acid. Adjust the pressure of the raw gas to the value required for inspection of the pressure cutter 31, and check the valve while watching the flowmeter 30. 29 to adjust the oxygen flow rate. When oxygen is ejected, this oxygen becomes a carrier flow. The downstream side is depressurized from the valve 13 that closes the acetylene line 6. . This reduced pressure is under normal operating conditions, for example, in the gas mixer 5 -0.5 to 9/cr. A to -0.4 kg/ci, and this reduced pressure value is indicated on the pressure gauge 18. This decrease If the pressure value is within the allowable range, the above gas mixing device is in normal operation and spraying is activated. is in a state of possibility. If the above pressure reduction is not performed or this pressure reduction is not appropriate, For safety reasons, spraying is not allowed.
上記減圧をできず、又は適切に行ない得ない時は上記ガス混合装＠５に異常、た とえば閉塞、ゆるみ等が生じているか、又はアセチレンガス供給ライン６にゆる みがある場合である。この状態が所定時間継続すれば上記制御システム４０が自 動的に［ガス混合装置正常作動確認モード］を停止させ、弁２７，３２．１９を 初期位置に戻す。If the above pressure reduction cannot be carried out or cannot be carried out properly, there is an abnormality in the above gas mixing device @5. For example, if there is a blockage, looseness, etc., or if there is a looseness in the acetylene gas supply line 6. This is the case when there is a difference. If this state continues for a predetermined period of time, the control system 40 will automatically Dynamically stop [gas mixing device normal operation confirmation mode] and close valves 27, 32.19. Return to initial position.
ガス混合装置５の正常作動確認できれば、作業員は制御システム４０を操作して 「アセチレン通気モード」にする。このモードでは、点火栓４は未だ作動せず、 圧力計１４の各接点３４，３６．３８と圧力真空計１８との電気的接続は断たれ ている。アセチレンライン６の通常閉じられる補助弁１３が開かれ、このライン ６の通常閉じられる主弁１９が未だ閉じた状態である。上記「ガス混合装置正常 状態確認モード」の間、アセチレンライン６が減圧され、アセチレンガスが上記 アセチレンライン６の中を、アセチレンガス供給源装置１０が開かれた弁１３、 減圧弁１５、予め調節して開かれた弁１６及び流量計１７を通って上記主弁１９ まで流れる。If the normal operation of the gas mixing device 5 is confirmed, the worker operates the control system 40. Set to "acetylene ventilation mode". In this mode, the spark plug 4 is not yet activated, The electrical connection between the contacts 34, 36, 38 of the pressure gauge 14 and the pressure vacuum gauge 18 is cut off. ing. The normally closed auxiliary valve 13 of the acetylene line 6 is opened and this line The normally closed main valve 19 of No. 6 is still closed. Above “Gas mixing device normal” During the “Status Check Mode”, the acetylene line 6 is depressurized and the acetylene gas is In the acetylene line 6, an acetylene gas supply device 10 opens a valve 13, The main valve 19 passes through the pressure reducing valve 15, the pre-adjusted open valve 16 and the flow meter 17. flows up to
作業員は減圧弁１５を操作してアセチレンガスの圧力を調節し、圧力真空計１８ を見ながら上記アセチレンガスの圧力を吹付は作業可能の圧力にして、弁１６を 閉じる。上記［アセチレン通気モード］はプリセットされた所定時間経過後に制 御システム４０からの信号によって終了し、補助弁１３が初期の閉鎖位置に戻さ れるし、爆発炎吹付は装置が吹付は作動可能の状態になる。The worker operates the pressure reducing valve 15 to adjust the pressure of the acetylene gas, and the pressure vacuum gauge 18 While watching, set the pressure of the acetylene gas to a working pressure and close the valve 16. close. The above [Acetylene ventilation mode] will be disabled after a preset period of time has elapsed. A signal from the control system 40 causes the auxiliary valve 13 to return to its initial closed position. The device will be ready for explosive flame spraying.
作業員が制御システム４０を操作して「吹付はモード」にすると、アセチレンラ インの圧力計１４の接点３４．３６及び圧力真空計１８の接点３８と、酸素ライ ン８の圧力計の接点３５．３７とがガス供給制御装置３９に電気的に接続される 。上記アセチレンガス及び酸素の圧力が所定の工程を行なうためのプリセットさ れた範囲内にあるならば、すなわち上記接点３４乃至３７と制御システム４０と を電気的に接続するり一ド線に信号が来なければ、制御システム４０の押しボタ ン（図示せず）を押して、アセチレンガス供給ライン６の通常閉じられる補助弁 １３及び主弁１９と、酸素ライン８の弁２７．３２とに同時にガスを供給す経過 するまでの間、開かれており（ただし、ガスの圧力がプリセットされた範囲内に あることを条件とする）、アセチレンガス及び酸素は爆発筒１の能力に応じて定 められた流量で供給され、この爆発筒１の能力に応じてガス混合装＠５のパラメ ータ及び上記制御システム４０からの点火栓４に送る放電パルスの速さが決まる 。When the worker operates the control system 40 to set the "spraying mode", acetylene Contacts 34 and 36 of the pressure gauge 14 and contacts 38 of the pressure vacuum gauge 18 and the oxygen line The contacts 35 and 37 of the pressure gauge of the cylinder 8 are electrically connected to the gas supply control device 39. . The above acetylene gas and oxygen pressures are preset to carry out the specified process. In other words, if the contacts 34 to 37 and the control system 40 If there is no signal on the first wire when electrically connected, the pushbutton on the control system 40 Press the button (not shown) to open the normally closed auxiliary valve in the acetylene gas supply line 6. 13 and the main valve 19 and the valves 27 and 32 of the oxygen line 8 at the same time. (unless the gas pressure is within the preset range) ), acetylene gas and oxygen are regulated according to the capacity of the explosive cylinder 1. The parameters of the gas mixing device @ 5 are adjusted according to the capacity of this explosive cylinder 1. The speed of the discharge pulse sent to the spark plug 4 from the controller and the control system 40 is determined. .
たとえば仮にアセチレンライン６に緩みがある状態で上記押しボタンを押せば、 アセチレンガス供給源装置１０からアセチレンライン６へのアセチレンガスの供 給は自動的に保留され（このような状態ではアセチレンライン６の圧力が圧力計 １４にプリセットされた値より下がるからであり）、ガス供給装置３９に対して 弁１３及び弁１９，２７．３０を開くための信号が送られる。For example, if the above push button is pressed while the acetylene line 6 is loose, Supply of acetylene gas from the acetylene gas supply source device 10 to the acetylene line 6 supply is automatically withheld (in this condition, the pressure in acetylene line 6 is indicated by the pressure gauge). 14) and for the gas supply device 39. A signal is sent to open valve 13 and valves 19, 27, 30.
上記と全く同様に、吹付は中にアセチレンライン６にゆるみが生ずれば、接点３ ６からガス供給制御装置３９に信号が送られ、この信号により直ちに弁１３゜１ ９．２７．３２が閉じられて上記ガスの供給が停止される。In exactly the same way as above, if the acetylene line 6 becomes loose during spraying, contact 3 6 sends a signal to the gas supply control device 39, and this signal immediately closes the valve 13°1. 9.27.32 is closed and the supply of said gas is stopped.
極めて重要なことは、上記通常閉じられる補助弁１３がアセチレンライン６を閉 じることであり、この補助弁１３の取付は位置が上記アセチレンガス供給源装置 １０のすぐ下流側にあり、上記建屋の外壁を貫いて延びるアセチレンライン６の 入口の位置より上流側にあることである。従って、上記建屋の中に送られるアセ チレンの量は上記アセチレンガス供給源装置１０が供給できるガスの流量に係ら ず、上記アセチレンガス供給ラインの弁１３から弁１９までの部分の長さの極め て限定された容量によってのみ支配される（従って、上記アセチレンライン６の 弁１３と弁１９との間の部分の内径ｄが１１０１ｎであり、長さ１が２００ｍで あれば、上記建屋の屋内に送り込まれるアセチレンガスの最大流量ｖ１は０．０ １６′ｒｄである。）ある上記通常閉じられる補助弁１３を閉じることにより行 ない、この補助弁１３は、緊急事態の早期発見、アセチレンガス供給源装置を作 業員から隔離して適当な位置からの遠隔操作、作業員の熟練度及び適切な動作、 その他の人間側の努力によって閉じることもできる（ここで注意すべきことは、 比較のために説明すれば、アセチレンガス供給源装置のガス供給能力ｑが１０Ｔ Ｉｔ毎秒であり、これが容量１リツトルの爆発筒１である場合に、これに応じた 点火栓の放電速度が６パルス毎秒であり、建屋内へのアセチレンガスの送込量■ １が１．６７１ｔであり、補助弁１３がない場合には、アセチレンガス供給源装 置６の上記部分にゆるみが生じてガス漏洩が始まってから人手でアセチレンの供 給を止めるまでには１０分間必要である。）本発明に基づく上記爆発炎吹付は装 置は、その酸素ライン８にゆるみが生じた場合にも、上記と同様、次のように作 用する。What is extremely important is that the normally closed auxiliary valve 13 closes the acetylene line 6. The auxiliary valve 13 is installed at a position close to the acetylene gas supply source device. The acetylene line 6, which is located immediately downstream of 10 and extends through the outer wall of the above building, It is located upstream from the entrance position. Therefore, the assets sent into the above building are The amount of tyrene depends on the flow rate of gas that can be supplied by the acetylene gas supply source device 10. First, determine the length of the acetylene gas supply line from valve 13 to valve 19. (Thus, the capacity of the acetylene line 6 above is The inner diameter d of the part between valve 13 and valve 19 is 1101n, and the length 1 is 200m. If so, the maximum flow rate v1 of acetylene gas sent into the interior of the above building is 0.0. It is 16'rd. ) by closing the normally closed auxiliary valve 13. No, this auxiliary valve 13 is used for early detection of emergencies and for creating an acetylene gas supply source device. Remote control from an appropriate location separated from the workers, the skill level of the workers and appropriate movement, It can also be closed by other human efforts (it should be noted here that For comparison, the gas supply capacity q of the acetylene gas supply source device is 10T. It per second, and if this is an explosive cylinder 1 with a capacity of 1 liter, the corresponding The discharge rate of the spark plug is 6 pulses per second, and the amount of acetylene gas sent into the building is 1 is 1.671t, and if there is no auxiliary valve 13, the acetylene gas supply equipment After the above part of the installation 6 became loose and gas leakage started, the acetylene was not supplied manually. It takes 10 minutes to stop feeding. ) The above explosive flame spray according to the present invention is Even if the oxygen line 8 becomes loose, the system should be operated as follows in the same manner as above. use
もし、アセチレンライン６の圧力が、上記アセチレンガス供給源装ｆｆ１１０の 調整ミスその他の原因で、上記アセチレンライン６（減圧弁１５より上流側の部 分）でプリセットされた圧力を越えた場合には、上記プリセットされた最大圧力 に対応する接点３４とガス供給制御装置３つとを電気的に接線する線に信号が送 られ、この信号によってアセチレンライン６及び酸素ライン８の補助弁１３．２ ７及び主弁１９．３２が閉待人昭６１−５０２３１７ （６） しられろく又は開かないようになる）。このようにすることにより、アセチレン ライン６の危険度をドげるごとができる。アセチレンラインは圧力が高くなる程 危険度が高く、圧力が高い程流れ方が安定するからでまた調整ミスによって吹付 は作業中に調圧弁１５が機能しなくなった場合、又はガス混合装置５もしくは逆 止弁２０に閉塞が生じた場合には、弁１９より上流側のアセチレンガスの圧力が 所定の作業条件のためにプリセットした値より高くなり、圧力真空計１８の最大 圧力に対応する接点とガス供給装置３９とを電気的に接続する線に信号が送られ 、この信号によって上記弁１３．１９，２７．３２が直ちに閉じられるので。If the pressure in the acetylene line 6 is Due to an adjustment error or other cause, the acetylene line 6 (the part upstream of the pressure reducing valve 15) If the preset pressure is exceeded in minutes), the preset maximum pressure above A signal is sent to the wire that is electrically tangential between the contacts 34 corresponding to the three gas supply control devices. This signal activates the auxiliary valve 13.2 of the acetylene line 6 and oxygen line 8. 7 and main valve 19.32 are closed 1986-502317 (6) (becomes difficult to open or does not open). By doing this, acetylene It is possible to lower the danger level of line 6. The higher the pressure on the acetylene line, the more The risk is high because the higher the pressure, the more stable the flow, and misadjustment may cause spraying. If the pressure regulating valve 15 stops functioning during work, or if the gas mixing device 5 or If the stop valve 20 becomes clogged, the pressure of the acetylene gas upstream of the valve 19 will decrease. The maximum value of the pressure vacuum gauge 18 is higher than the preset value for the given working conditions. A signal is sent to a line that electrically connects the contact corresponding to the pressure and the gas supply device 39. , since this signal immediately closes the valves 13.19, 27.32.
アセチレンガス及び酸素ガスの供給が停止される。The supply of acetylene gas and oxygen gas is stopped.
また仮に、酸素ガスの圧力が、ガス混合装置５の誤作動（たとえば閉塞）又は減 圧弁２８の誤調整もしくは調整機能喪失のために、所定の操業条件維持に必要な 圧力より高くなった場合には、ガス供給制御装置３９と圧力計３１の接点３５と を接続する線に仁君が送られて、弁１３，１９，２７．３２によりガスの供給が 止められる。Also, if the pressure of oxygen gas malfunctions (for example, is blocked) or decreases, Due to incorrect adjustment or loss of adjustment function of the pressure valve 28, the If the pressure becomes higher than the pressure, the contact point 35 of the gas supply control device 39 and the pressure gauge 31 Jin-kun is sent to the line connecting the It can be stopped.
アセチレンガス供給源装置１０及び酸素ガス供給源装置１２が空になった場合も 、ガスが供給されなくなるのは当然である（このことは、実際には上記爆発炎吹 付は装置が作動しなくなることを意味する〉。このような場合、圧力計ｉ４．３ １の接点３６．３７がそれぞれ作動する。Also when the acetylene gas supply source device 10 and the oxygen gas supply source device 12 are empty , it is natural that the gas supply would be cut off (this actually means that the explosion The mark means that the device will no longer work. In such a case, the pressure gauge i4.3 1 contacts 36 and 37 are activated, respectively.

It is possible to distinguish between the flames flowing up to the If acetylene line 6 shows acetylene If the gas is burning, the pressure upstream from the gas mixing device 5 will rise. Therefore, a signal is sent from the contact 38 of the pressure vacuum gauge 18 to the gas supply device 39, and this Gas supply bag @39 actuates valves 13, 19, 27, 32. operate this valve The reason is that this valve 13°19.27.32 receives the signal from the microphone 42. This is a case where it is removed before it disappears. In addition, if the spark plug 4 malfunctions, the pressure Vacuum gauge 18 does not work. The above-mentioned explosive spraying device ignited the gas mixing device 5. After the flame is extinguished, that is, after the signal from contact 38 disappears, Only later can the recurrent operation be initiated.
上記吹付【プブースに爆発の危険があり、換気装置が故障し、吹付はブースの中 でガス供給ラインの破断その他の緊急事態が発生した場合は、作業員は高圧の窒 素ガスを用いて防炎装置２０、ガス混合装置５、点火室３及び爆発筒１を一気に 掃気する。そのためには、制御システム４０の緊急ボタン（図示せず）を押して 弁４８を開く。The above spraying [there was a risk of explosion in the booth, the ventilation system was broken, and the spraying was carried out inside the booth. In the event of a gas supply line rupture or other emergency, personnel should use high-pressure nitrogen Using raw gas, fireproofing device 20, gas mixing device 5, ignition chamber 3, and explosive tube 1 all at once. Scavenge. To do so, press the emergency button (not shown) on the control system 40. Open valve 48.
これと同時に弁１３，１９，２７．３２が（間けであるならば）閉じられる。窒 素ガスは、上記管路４５から開いている弁４８及び逆止弁４９を経てアセチレン ラインの通常閉じられる弁１９の下流側に送られで、防炎装置２０、ガス混合装 置５、点火室３および爆発筒１を掃気する。At the same time, valves 13, 19, 27, 32 are closed (if only intermittently). nitrogen The raw gas passes through the open valve 48 and check valve 49 from the pipe 45 to acetylene. The line is routed downstream of the normally closed valve 19 and includes a flame retardant device 20 and a gas mixing device. The chamber 5, the ignition chamber 3 and the explosive tube 1 are scavenged.
−Ｆ記［緊急１状態は、上記制御装置４０にプリセットさねた時間経過役、自動 的に解除され、必要に応じて上記「緊急」状態とその解除を所定回数反覆する（ ただし、窒素ガスが窒素ガス供給源装置１１にある間だけである）。上記ブース の窒素の濃度が何等かの原因で爆発を妨げる濃度になった場合（２容量％を越λ に場合）には、ガス分析装置の検知器４３が制御システム４０に信号を送り、自 動的に上述のように「緊急モード１を開始させる。- Note F [Emergency 1 state is the time elapsed function preset in the control device 40, automatic The above “emergency” state and its release may be repeated a predetermined number of times as necessary ( However, this is only while nitrogen gas is present in the nitrogen gas supply source device 11). The above booth If the concentration of nitrogen in the tank reaches a concentration that prevents an explosion for some reason (over 2% by volume) ), the detector 43 of the gas analyzer sends a signal to the control system 40 to automatically Dynamically “start emergency mode 1” as described above.
上記「吹付はモード」終了後（たとえば就業日の終業時）に、作業員は制御シス テム４０に１アセチレンライン掃気モード」の指令を与える。そうすれば、アセ チレンガス供給ライン６の弁１９と通常閉じられている弁４６が同時に開かれる 。アセチレンライン６の弁１３は初期状態（閉じられた状態）のままである。After the above “spraying mode” ends (for example, at the end of the working day), the operator A command for "1 acetylene line scavenging mode" is given to system 40. If you do that, Valve 19 of the chilli gas supply line 6 and normally closed valve 46 are opened at the same time. . The valve 13 of the acetylene line 6 remains in its initial state (closed state).
窒素ガスは、アセチレンガス供給管６の外壁９を貫いて上記建屋の中に入る位置 の上流側で、開かれた弁４６及び逆１弁４７を通り、管路４４から上記アセチレ ンガス供給ライン６に流入する。The nitrogen gas enters the building through the outer wall 9 of the acetylene gas supply pipe 6. On the upstream side of The gas flows into the gas supply line 6.
窒素ガスはアはチレンライン６、ガス混合装置５、点火室３及び爆発筒１の中を 流れてアセチレンガスを駆逐すなわち掃気し、制御システム４０は、［吹付（プ モード」の場合と同様、点火栓４に放電電流をパルス状に与える。爆発筒１に送 り込まれるガスに点火できる最のアセチレンが含まれている間は、このアセチレ ンは爆発筒１の中で燃焼する。この「アセチレンガス掃気モード」はプリセット された時間が経過すると自動的に停止される。窒素ガスは、上記爆発炎吹イ（１ け装置がすでに説明した「ガス混合装置正常状態確認モード」にすれば自動的に 除去される。Nitrogen gas flows through the ethylene line 6, gas mixer 5, ignition chamber 3, and explosion tube 1. The flow displaces or scavenges the acetylene gas, and the control system 40 As in the case of ``mode'', a discharge current is applied to the ignition plug 4 in a pulsed manner. Send to explosive tube 1 As long as the incoming gas contains the most acetylene that can be ignited, this burns in the explosive tube 1. This "acetylene gas scavenging mode" is preset. It will automatically stop after the specified time has elapsed. Nitrogen gas is If the device is set to the “gas mixing device normal status confirmation mode” described above, it will automatically removed.
本発明に基づく上記爆発製吹付は装置の逆止弁４７は管路４４及び弁４６にアセ チレンガスが入らないようにする。逆止弁２６．３３．４９も、制御される弁２ ５．３２．４８からアセチレンガスが窒素ライン７、酸素ライン８、及び管路４ ５の出口側に入るのを防ぐ。In the explosive spray according to the invention, the check valve 47 of the device is connected to the line 44 and the valve 46. Prevent chillen gas from entering. Check valve 26.33.49 is also controlled by valve 2 5.32.48 Acetylene gas is transferred to nitrogen line 7, oxygen line 8, and pipe 4 Prevent from entering the exit side of 5.
本発明に基づく爆発製吹付は装置の作用について重。要なことは、上述のように 何等かの停止信号が発せられると、上記ラインの通常閉じられる２対の弁が同時 に閉じられることである。Explosive spray according to the invention has important implications regarding the operation of the device. The important thing is, as mentioned above When a stop signal of some kind is issued, the two normally closed valves in the above line close simultaneously. It is to be closed to.
仮に１個の弁、たとえば通常閉じられる主弁１９の故障（たとえば閉まるべき時 に閉まらない場合）の発生確率ｎ１が１０ （すなわち作動１０００回当りの故 障発生回数が１回）であるとすれば、直列に組み込まれた２個の弁、たとえば通 常閉じられる補助弁１３け装置の信頼性は実質的に改善される。この観点から、 たとえばアセチレンライン６の弁１９が閉じられた後に上記ブースに爆発をひき 起こす程多吊のアセチレンガスが送られることはない。その理由は、アセチレン ガス供給源装置１０が通常閉じられる補助弁１３によって閉じられた状態にある からである。この場合、上記ブースの容積に比べれば僅少であるがアセチレンラ イン６の中に残留するアセチレンだけが上記ブースに送られる（アセチレンライ ンの容積ｖ２が０．０１６尻であり、ブースの容積Ｖ３が２．０ｍであるとづれ ば、このブースにおけるアセチレンガスの濃度Ｃは Ｃ＝ （０，０１６／２）ｘｌ ００ （％）−〇、８％く２％ −ひある）。これと同様に、弁１９が閉じられた後にゆるんでも、たとえばガス 混合装置５まで火炎が遡上した場合でも、その炎が燃え続ける時間は余り長くは ならない。その理由はアセチレンガス供給源装置１０が弁１３によって閉じられ ているので、アセチレンガスが供給されないからである。If one valve, for example the main valve 19 which is normally closed, fails (for example when it should be closed) The occurrence probability n1 is 10 (in other words, if the failure occurs per 1000 operations) If the number of failures is 1), two valves installed in series, for example, The reliability of the normally closed auxiliary valve system is substantially improved. From this point of view, For example, after valve 19 of acetylene line 6 is closed, an explosion may occur in the booth. Acetylene gas is not sent in sufficient quantities to cause this. The reason is that acetylene The gas source device 10 is in a closed state by the normally closed auxiliary valve 13 It is from. In this case, although it is small compared to the volume of the booth mentioned above, the acetylene Only the acetylene remaining in In-6 is sent to the above booth (acetylene light The volume v2 of the booth is 0.016m, and the volume V3 of the booth is 2.0m. For example, the concentration C of acetylene gas in this booth is C = (0,016/2) xl 00 (%) - 〇, 8% × 2% -Hiaru). Similarly, even if the valve 19 becomes loose after being closed, e.g. Even if the flame reaches the mixing device 5, the flame will not continue to burn for too long. No. The reason is that the acetylene gas supply device 10 is closed by the valve 13. This is because acetylene gas is not supplied.
