본 발명은 벨로우즈가 설치된 LNG 벙커링 장치에 관한 것으로, 선박에 극저온인 LNG가스를 주유하는 벙커링 장치(100)에 벨로우즈(140)를 설치하여 파도에 의한 흔들림 및 외부의 충격으로 인해 경화된 호스(150)가 파괴되는 것을 막을 수 있는 것이다.The present invention relates to an LNG bunkering device in which bellows are installed. The bellows 140 is installed in the bunkering device 100 for supplying cryogenic LNG gas to a vessel, and thus, the hose 150 hardened due to shaking due to waves and external impact. ) Can be destroyed.

상기 벙커링 장치는 선박 외부의 연료탱크에서 선박의 연료탱크로 LNG가스를 주입하는 장치이다.The bunkering device is a device for injecting LNG gas into the fuel tank of the vessel from the fuel tank outside the vessel.

상기 LNG가스는 -162℃인 극저온 액화가스이다.The LNG gas is a cryogenic liquefied gas of -162 ℃.

상기 호스는 극저온용 호스를 사용하는 것으로, 스테인레스 재질이며, 호스내부로 LNG가스가 유입되면 호스는 경화된다.The hose uses a cryogenic hose, which is made of stainless steel, and hardens when the LNG gas is introduced into the hose.

상기 벙커링 장치(100)는 선박 외부의 연료탱크에 저장되어 있는 LNG가스를 선박의 연료탱크로 주유하는 것으로서, 상기 연료탱크의 주입구와 선박 외부의 연료탱크 배출구에 각각 설치되는 것이다.The bunkering device 100 is to supply LNG gas stored in a fuel tank outside a ship to a fuel tank of a ship, and is installed at an injection port of the fuel tank and a discharge port of a fuel tank outside the ship, respectively.

즉, 상기 선박 외부의 연료탱크에 저장되어 있는 LNG가스는 별도로 설치된 연료공급펌프에 의해 선박 외부의 연료탱크에서 선박의 연료탱크로 주유되되, 상기 선박 외부의 연료탱크와 선박의 연료탱크에는 각각 벨로우즈가 설치된 벙커링 장치(100)가 설치되어 있어, LNG가스 주유중 경화된 호스가 파도에 의한 흔들림 및 외부의 충격으로 인해 파괴되는 것을 막을 수 있는 것이다.That is, the LNG gas stored in the fuel tank outside the vessel is supplied to the fuel tank of the vessel from the fuel tank outside the vessel by a fuel supply pump installed separately, the bellows to the fuel tank and the fuel tank of the vessel, respectively Is installed bunkering device 100 is installed, it is possible to prevent the hose hardened in LNG gas oil is destroyed by the shaking due to waves and external impact.

상기 벙커링 장치(100)는 호스(150), 벨로우즈(140), 응급릴리스커플링(110), 퀵커넥터(120), 디스커넥터(130), 벨로우즈(140), 호스(150) 순으로 이루어진다.The bunkering device 100 includes a hose 150, a bellows 140, an emergency release coupling 110, a quick connector 120, a disconnector 130, a bellows 140, and a hose 150.

그리고 LMG가스는 응급릴리스커플링(110)에서 퀵커넥터(120), 디스커넥터(130)이 설치된 방향으로 주유된다.The LMG gas is lubricated in the direction in which the quick connector 120 and the disconnect connector 130 are installed in the emergency release coupling 110.

Emergency release coupling is generally located between the manifold and the hose of the receiving vessel, and emergency release coupling operates at cryogenic temperatures.

상기 퀵커넥터(120), 디스커넥터(130)는 서로결합되는 것으로, QCDC라고 하며, LNG터미널이라고도 한다. 비상상황에서 LNG가스를 차단하기 위한 장치이다. 즉, 상기 LNG가스를 하역하고 있는 중에 바로 분리되면 위험하므로, LNG가스를 차단한 후에 분리가 되는 것으로, 선박의 연료탱크와 선박외부의 연료탱크 사이의 배관을 볼밸브로 차단하는 것이다.The quick connector 120 and the disconnect connector 130 are coupled to each other, referred to as QCDC, also referred to as an LNG terminal. It is a device to block LNG gas in emergency situation. In other words, if the LNG gas is immediately unloaded while being unloaded, it is dangerous. After the LNG gas is shut off, the gas is separated and the pipe between the fuel tank of the ship and the fuel tank outside the ship is blocked by a ball valve.

상기 LNG가스가 차단된 후에 가운데 부분이 분리되면서 한쪽은 선박에 매달려 있고 한쪽은 선박 외부의 연료탱크에 매달리게 된다.After the LNG gas is blocked, the middle part is separated and one side is suspended from the vessel and one side is suspended from the fuel tank outside the vessel.

그리고 상기 LNG가스를 차단하여 분리하는 시스템은 이미 널리 알려진 관용의 것으로서, 등록특허공보 등록번호 제10-0445323호의 선박용 비상정지시스템에 기재되어 있으므로 자세한 설명은 생략한다.In addition, the system for blocking and separating the LNG gas is already well known, and is described in the emergency stop system for ships in Korean Patent Publication No. 10-0445323, detailed description thereof will be omitted.
