다음으로 상기 차단밸브(50)와 차단밸브(50)의 사이에 위치한 연결배관(40)에 소정의 길이를 가지는 압력도출밸브 배관(70)을 장착한 후 상기 압력도출밸브 배관(70)에 압력도출밸브의 배관장치가이드(80)가 연결된 압력도출밸브(60)를 연결장착하면 액체이산화탄소 운반선의 화물 관장치 및 관장치 요소용 압력도출밸브의 배출 배관장치의 조립은 완료되는 것이다. Next, the pressure relief valve pipe 70 having a predetermined length is attached to the connection pipe 40 positioned between the shutoff valve 50 and the shutoff valve 50, and then the pressure is released from the pressure relief valve pipe 70. When the pressure relief valve 60 connected to the piping device guide 80 of the relief valve is connected and installed, the assembly of the discharge piping device of the pressure relief valve for the cargo piping device and the piping device of the liquid carbon dioxide carrier is completed.

여기서, 액체이산화탄소 운반선의 화물 관장치 및 관장치 요소용 압력도출밸브의 배출 배관장치의 조립 순서는 상기와 다르게 구성될 수 있음을 밝힌다.
Here, the assembling order of the discharge piping of the pressure relief valve for the cargo piping device and piping device elements of the liquid carbon dioxide carrier ship can be configured differently from the above.

다음으로 상기 액체이산화탄소 운반선의 화물 관장치 및 관장치 요소용 압력도출밸브의 배출 배관장치의 사용상태를 살펴보면 다음과 같다. Next, look at the state of use of the discharge piping of the pressure relief valve for the cargo piping device and piping device elements of the liquid carbon dioxide carrier.

먼저, 상기 운반선(20)의 화물탱크(30)에 액체이산화탄소를 충만한 후 상기 운반선(20)을 이동시킨다. First, after filling the liquid carbon dioxide in the cargo tank 30 of the carrier 20 moves the carrier 20.

상기와 같은 상태에서 상기 운반선(20)의 연결배관(40)에 외부로부터 인입된 열이 전달되면, 상기 연결배관(40)의 내부에 수용된 액체이산화탄소는 증발하면서 액체화물 및 액?증기 혼합물을 발생하고, 상기 액체화물 및 액?증기 혼합물은 연결배관(40) 및 차단밸브(50)를 따라 이동한다. In the above state, when the heat drawn from the outside is transferred to the connection pipe 40 of the carrier ship 20, the liquid carbon dioxide contained in the connection pipe 40 generates a liquid cargo and a liquid-vapor mixture while evaporating. The liquid cargo and the liquid and vapor mixture are moved along the connecting pipe 40 and the shutoff valve 50.

즉, 상기 연결배관(40)의 내부에 수용된 액체이산화탄소는 도시된 도 3과 같이 압력 7bar와 -55의 온도 이상이 되면 액체화물 및 액?증기 혼합물을 발생하여 연결배관(40) 및 차단밸브(50)를 따라 이동하게 되는 것이다. That is, the liquid carbon dioxide accommodated in the connection pipe 40 generates a liquid cargo and a liquid-vapor mixture when the pressure is 7 bar and the temperature of -55 or more as shown in FIG. 3, thereby connecting the connection pipe 40 and the shutoff valve ( 50).

다음으로 상기 연결배관(40) 및 차단밸브(50)를 따라 이동하는 액체화물 및 액?증기 혼합물은, 상기 차단밸브(50)와 차단밸브(50)의 사이에 연결장착되는 압력도출밸브 배관(70)을 따라 압력도출밸브(60)에 전달된 후, 상기 압력도출밸브(60)와 연결된 압력도출밸브의 배관장치가이드(80)를 따라 외부로 안전하게 배출하게 되는 것이다. Next, the liquid cargo and the liquid-vapor mixture moving along the connecting pipe 40 and the shutoff valve 50 are connected to the pressure relief valve pipe between the shutoff valve 50 and the shutoff valve 50. After being delivered to the pressure relief valve 60 along 70, it is safely discharged to the outside along the piping device guide 80 of the pressure relief valve connected to the pressure relief valve 60.

그리고 상기 연결배관(40)의 압력이 규정 이하로 되면 상기 압력도출밸브(60)는 작동을 멈추고 내부를 밀폐하여 처음 상태를 유지하는 과정을 연속적으로 거치게 되는 것이다. And when the pressure of the connection pipe 40 is less than the specified, the pressure relief valve 60 is to go through the process of stopping the operation and sealing the inside to maintain the initial state.

이상에서 첨부된 도면을 참조하여 본 발명인 액체이산화탄소 운반선의 화물 관장치 및 관장치 요소용 압력도출밸브의 배출 배관장치를 설명함에 있어 특정형상 및 방향을 위주로 설명하였으나, 본 발명은 당업자에 의하여 다양한 변형 및 변경이 가능하고, 이러한 변형 및 변경은 본 발명의 권리범위에 포함되는 것으로 해석되어야 한다.
