本発明は、深海潜水度相当圧力に加圧して潜水
訓練に用いられる加圧潜水槽に関し、特にその圧
力を制御するための装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressurized diving tank that is pressurized to a pressure equivalent to deep-sea diving and used for diving training, and particularly to a device for controlling the pressure.
従来、加圧潜水槽では、第１図に示すように、
所定水量を注水した密閉可能な加圧潜水槽１に、
訓練ダイバー２が入つた後、ハツチふた３を閉鎖
し、加圧操作弁４を開き、ボンベ５から加圧用ガ
スを給気口６を介して気相部７に供給し、加圧潜
水槽１の内部を潜水訓練深度相当圧力となるまで
加圧することが行なわれている。 Conventionally, in pressurized diving tanks, as shown in Figure 1,
A sealable pressurized diving tank 1 is filled with a predetermined amount of water.
After the training diver 2 enters, the hatch lid 3 is closed, the pressurization operation valve 4 is opened, pressurization gas is supplied from the cylinder 5 through the air supply port 6 to the gas phase section 7, and the pressurized diving tank 1 is The interior of the vessel is pressurized to a pressure equivalent to the diving training depth.
そして、加圧潜水槽１の内部圧力は、圧力計８
で監視されるとともに、圧力検出器９で検知さ
れ、圧力制御器１０に予め設定してある潜水訓練
深度相当圧力以上となれば、自動放気弁１１が開
いて放気口１２から気相部７のガスを放出するよ
うになつている。 The internal pressure of the pressurized diving tank 1 is determined by the pressure gauge 8.
When the pressure is detected by the pressure detector 9 and exceeds the pressure equivalent to the diving training depth preset in the pressure controller 10, the automatic air release valve 11 opens and the gas phase is released from the air release port 12. It is designed to emit 7 gases.
ついで、加圧操作弁４を閉鎖して加圧用ガスの
供給を停止し、加圧潜水槽１の内部圧力が設定圧
力範囲以内になつたとき、自動放気弁１１が閉鎖
され、加圧潜水槽１は潜水訓練深度相当圧力に設
定される。 Next, the pressurization operation valve 4 is closed to stop the supply of pressurizing gas, and when the internal pressure of the pressurized diving tank 1 falls within the set pressure range, the automatic release valve 11 is closed and pressurized diving is started. Tank 1 is set to a pressure equivalent to the diving training depth.
また、訓練ダイバー２には、ボンベ１３からの
潜水呼吸ガスが、呼吸ガス供給操作弁１４および
潜水呼吸ガス供給ホース１５を介して供給され、
この訓練ダイバー２は潜水呼吸器１６を用いて潜
水呼吸ガスを呼吸し、呼気を気泡１７として排気
する。 Further, the training diver 2 is supplied with diving breathing gas from the cylinder 13 via the breathing gas supply operation valve 14 and the diving breathing gas supply hose 15,
This training diver 2 breathes in diving breathing gas using a diving breathing apparatus 16 and exhausts exhaled air as bubbles 17.
このため、排気された呼気の溜まる気相部７内
の圧力は、徐々に上昇し、制御器１０の設定圧力
以上になると、自動放気弁１１が開き、放気口１
２から気相部７のガスが放出され、設定圧力範囲
内になると、自動放気弁１１が閉鎖されることに
よつて、加圧潜水槽１の内部圧力は一定に保持さ
れる。 Therefore, the pressure in the gas phase section 7 where the exhausted exhaled air accumulates gradually rises, and when the pressure exceeds the set pressure of the controller 10, the automatic release valve 11 opens and the air release port 1 opens.
When the gas in the gas phase part 7 is released from the pressure diving tank 2 and the pressure falls within the set pressure range, the automatic release valve 11 is closed, thereby maintaining the internal pressure of the pressurized diving tank 1 constant.
このような圧力保持の精度は、設定圧力±0.1
Kgｆ／cm2以内となることが必要とされ、訓練ダイ
バー２に関しては、到達圧力精度よりも、その後
の圧力保持精度が重要となる。 The accuracy of such pressure holding is ±0.1 of the set pressure.
Kgf/cm 2 or less, and for the training diver 2, the subsequent pressure holding accuracy is more important than the ultimate pressure accuracy.
このため、潜水訓練深度相当圧力が増大する
と、圧力検出器９に、より高い検出精度が要求さ
れる。例えば、潜水訓練深度相当圧力を50Kgｆ／
cm2とした場合、±0.1Kgｆ／cm2の圧力保持精度を得
るには、0.2％の制御精度が必要となる。 Therefore, when the pressure corresponding to the diving training depth increases, the pressure detector 9 is required to have higher detection accuracy. For example, the pressure equivalent to diving training depth is 50Kgf/
cm 2 , a control accuracy of 0.2% is required to obtain a pressure holding accuracy of ±0.1 Kgf/cm 2 .
従来の加圧潜水槽１の圧力制御装置のように、
圧力検出器９を用いる制御では、圧力検出器９自
体の検出精度が、一般にフル・スパンの0.2％程
度とされているので、制御精度はこれより低くな
るという問題点がある。 Like the pressure control device of the conventional pressurized diving tank 1,
In control using the pressure detector 9, the detection accuracy of the pressure detector 9 itself is generally about 0.2% of the full span, so there is a problem that the control accuracy is lower than this.
また、潜水訓練深度相当圧力が増大すると、必
要な圧力保持精度を保持するうえでの制約が大き
くなるという問題点もある。 Another problem is that as the pressure equivalent to the diving training depth increases, restrictions on maintaining the required pressure holding accuracy become greater.
本発明は、これらの問題点の解消をはかろうと
するもので、圧力状態の高低にかかわらず、微小
圧力変化を検出し、高い圧力保持精度を確保でき
