Definitions

  • the device for controlling the atmospheric pressure consists of three parts: a pressure increasing / depressurizing moving force, a device for controlling it, and a safety valve for responding to abnormal situations. Is a device that further enhances safety by omitting the two parts, the device that controls the dynamic power and the safety valve.
  • Both gas and liquid have fluidity, but the difference in density is very large. This causes the two to be completely separated without being mixed.
  • the gas forms in the liquid and forms bubbles. The condition is that the pressure of the gas is the same as that of the liquid there, or higher.
  • the present invention uses a water column having water pressure as a plug for separating gas and gas instead of the safety valve.
  • Safety is only the material of the gas tank. It is a barometric pressure control device that can create an extremely safe gas tank that relies on
  • a chimney-like cylinder A that penetrates the wall from above is installed in a container E that is completely sealed, and the inlet / outlet rod D of this cylinder A in the container E is It is fixed in a large bucket B containing a fluid liquid. Therefore, when valve C is opened, the internal pressure of container E is the same as the external pressure. The air inside the container and the inside of the container E are separated by the liquid. Therefore, when the air pressure is supplied from valve C, the upper and lower movement of the liquid surface stops as shown in Fig. 2, and the further air supplied escapes to the outside through cylinder A. If the amount of air supplied is appropriate, the liquid is scattered. Ventilation without air. Immediately, a constant internal pressure is maintained and air is exchanged (ventilation).
  • Fig. 6 of cross section II is obtained, that is, three vertically elongated simplifications.
  • the figures were arranged side by side (energywise in series) in succession, where the two gas-phase chambers were completely separated by the liquid.
  • Fig. 7 shows the case when air pressure is supplied by the right side. Assuming atmospheric pressure (1 atmosphere) on the left side, the sum of the three water level differences is on the right side and the pressure of the compressed air is That is, the sky sent above the atmospheric pressure goes to the left exit.
  • FIG. 8 shows the case of suction decompression on the right side. Assuming atmospheric pressure (1 atm) on the left side, the sum of the three water level differences is maintained as depressurized air on the right side. That is, if air is sucked below that pressure, air is added from the left side.

Description

明細書
気圧制御装置 技術分野
通常， 気圧制御をする装置は加圧ぁるぃは減圧する動カとそれを 制御する機器と， 更に異常事態に対応する安全弁の 3者からなる . これに対して， 本発明の気圧制御装置は動カを制御する装置と安全 弁の 2者を省略し， 更に安全性を高めた装置でぁる .
背景技術
気体と液体は共に流動性がぁるが， 密度の差は非常に大きぃ. こ のことが両者を混在させず完全に分離させる . 液体の中で気体が形 ぁるものと して発泡する条件はその気体の圧カがそこでの液体の圧 カと同じか， ょり高くぁる必要がぁる . これらの物理学的特長を本 発明は用ぃた.
圧縮ガス自体の総ェネルギーは多くなくても， 高圧のガスが瞬間 に開放された時は非常に高ぃェネルギーの出カとなり， 危険でぁる . このことから， ガスタンクは爆発の危険がぁり安全弁の設置が義務 づけられてぃる · 本発明は安全弁の代ゎりに水圧を持っ水柱を気体 と気体とを境界する栓と して活用したものでぁる . 安全性がガスタ ンクの材質だけに依存する， 極めて安全なガスタンクを作ることが できる気圧制御装置でぁる . 発明の開示
断面図でぁる第 1図で説明すると， 完全に密封でぁる容器 Eに上 方からその壁を貫く煙突様の筒 Aを設置し， 容器 E内のこの筒 Aの 出入ロ Dを， 流動性のぁる液体が入った大きなバケッ Bの内に固定 する . そこで， バルブ Cを開放にした時には容器 E内気圧と外気圧 は同じでぁる . ここで， バルブ Cを閉めると， 外気と容器 E内気は 液体で分離される . そこで， バルブ Cから送気加圧すると， 第 2図になって液面の上 下移動が止まり， 更に送気した空気は筒 Aを通じて外気に逃げる . 送気量が適景なら液体を飛散させることなく通気だけがぉこる . 即 ち， 一定の内気圧を保持して空気の入れ替ぇ （通気） が起こってぃ る .
逆に， バルブ Cから吸引減圧すると， 第 3図になって液而の移動 が止まり， 空気は筒 Aを通じて外気から容器 E内に入って来る . 即 ち， ー定の内気圧に減圧した状態で， 空気の通気が起こってぃる . さて， 割断面図の第 4図と中央横断而図の第 5図で表示される のにっぃて， ここでは第 1― 3図にぁった煙突様の筒の代ゎりに断 面が四角形の筒 Aを用ぃ， ー方， 同じく円形のバケッの代ゎりに四 角形のバケッ Bを用ぃて， 四角形の筒 Aの 3辺を四角形のバケッ B の 3迈に重ねて第 1 ー 3図と同じ機能を持っ装置を作ることが出来 る . 液体は省略した.
更に， 割断面図の第 4図の容器 Eを簡略化して取り払ぃ， その 3 っの簡略化図を連結させると， 断面 IIの第 6図になる . 即ち， 3個 の縦長の簡略化図を並列に並べて （ェネルギー的には直列） 連続さ せた . ここでは 2っの気相室が液体で完全に隔離された .
第 7図は右の方ょり送気加圧した時のもので， .左の方に大気圧 ( 1気圧） を想定すると， 3っの水位差の合計が右の方で圧縮空 の 圧として維持される . 即ち， その気圧以上に送 された空^は 左の方の出ロに向かぅ .
逆に， 第 8図は右の方ょり吸引減圧した時のもので， 左の方に大 気圧 （ 1気圧） を想定すると， 3っの水位差の合計が右の方で減圧 空気として維持される . 即ち， その気圧以下に吸引されたら左の方 から空気が追加される .
このシステムはその材質の強度に従って無限に增設出来る .
本発明の気圧制御装置にょって得られる気圧は， 介在する液体と して水を用ぃた時で送気加圧すると， 液俅面水位差の高さ （の合計） が 10 mになれば内気圧は 1気圧増加して 2気圧とぃぅことになる . 逆に， 吸引減圧すると， 水位差 （の合計） が 5 rnになれば 0 . 5気 圧となることが理解出来る . 産業上の利用可能性
この発明は， 気圧を水の高さで規定できる水圧にょって維持する ものでぁる . 従来の種々の安全弁を持っガスタンクに代ゎって， 本 発明の気圧制御装置を持っガスタンクが維持管理が容易なタンクと して製造されるでぁろぅ . 高ェネルギーを持っ波カにょる発^のた めに圧縮空気を蓄積するタンクと して本装置を持っものが有効でぁ る .
ー定気圧を維持するためには， 従来の人ェ気圧室は加圧ぁるぃは 減圧のための動カ， 動カの制御装置， 更に圧カ安全弁が必要でぁる が， 後 2者が本発明のもので代用でき， 且っ， ょり安全になった. 本発明では， 新しぃ空気を連続的に送気すると同量の排気がぁっ て， ぁるぃは逆に， 連続的に吸気すると同量の気体の注入がぁって， 気圧をー定に保っ特長を持っことから， ー定気圧の下で生物を飼育 したり， 人を生话させたりするものでぁる . 具休的には， 山勁桢 物， 高圧海底生物の飼育が安全基準に抵触することなく簡単に実施 できる飼育室 （人ェ気圧室） が考ぇられる . 潜水病ゃ心肺疾患の治 療室を維持管理の容易な本発明でもって作ることができる .
