Description

통합 누수시험장치{LEAKAGE TESTER}Integrated Leak Tester {LEAKAGE TESTER}

본 발명은 선박에 설치된 각종 배관라인의 누수를 시험하기 위한 누수시험장치에 관한 것으로서, 특히 복수의 배관라인들을 통합하여 신속하게 시험할 수 있게 구성한 것이다.
The present invention relates to a leak test apparatus for testing leaks of various piping lines installed in a ship, and is particularly configured to be able to quickly test by integrating a plurality of piping lines.

선박에는 많은 배관라인이 위치하며 배관라인을 통해 유체 즉 기체 또는 액체가 이송된다. 이와 같이 배관라인을 통해 유체를 이송하기 위해서는 배관라인의 누수시험이 수행되어야 한다.There are many pipelines on the ship, and fluids, such as gases or liquids, are transferred through the pipelines. Thus, in order to transfer the fluid through the pipe line, the leak test of the pipe line should be performed.

도면에서 도 1은 종래 기술에 따른 누수시험장치를 나타낸 개념도이다.1 is a conceptual diagram showing a leak test apparatus according to the prior art.

도 1에 도시된 바와 같이, 누수시험장치(10)의 각 분기관(11)에 선박의 배관라인(1)을 연결하고, 분기관(11)에 장착된 밸브(11V)를 개방한다. 또한 배관라인(1)에 유체를 채우기 위해 누수시험장치(10)를 탱크(20)에 연결한 후 누수시험장치(10)의 통합 밸브(13V)를 개방한다. 그러면 탱크(20)에 채워진 유체가 누수시험장치(10)를 통해 선박의 배관라인(1)에 채워진다. 이 상태에서 누수시험장치(10)에서 탱크(20)로 연결된 연결라인(15)을 탱크(20)에서 해체한 후 해체된 연결라인(15)을 펌프(30)에 연결한다.As shown in FIG. 1, the pipe line 1 of the ship is connected to each branch pipe 11 of the leak test apparatus 10, and the valve 11V mounted on the branch pipe 11 is opened. In addition, after the leak test apparatus 10 is connected to the tank 20 to fill the pipe line 1, the integrated valve 13V of the leak test apparatus 10 is opened. Then, the fluid filled in the tank 20 is filled in the ship's pipe line 1 through the leak test apparatus (10). In this state, the connection line 15 connected to the tank 20 in the leak test apparatus 10 is dismantled in the tank 20, and then the disconnected connection line 15 is connected to the pump 30.

그리고 펌프(30)를 가동시키면 누수시험장치(10) 및 선박의 배관라인(1)에 압력이 가해지면서 누수시험이 진행된다.When the pump 30 is operated, a leak test is performed while pressure is applied to the leak test apparatus 10 and the ship's pipe line 1.

이와 같이 종래에는 누수시험장치(10)를 통해 배관라인(1)에 유체를 채운 후에 누수시험장치(10)를 펌프(30)에 연결하여야 하는 불편함이 있다. 또한, 유체가 탱크(20)에서 배관라인(1)으로 이송됨에 있어 높이에 따른 수압차에 의해 이송되기 때문에 누수시험장치(10) 및 탱크(20)의 위치를 배관라인(1)보다 높게 위치하여야 하는 위치적 제한이 따른다.
As such, there is a inconvenience in that the leak test apparatus 10 should be connected to the pump 30 after the fluid is filled in the pipe line 1 through the leak test apparatus 10. In addition, since the fluid is transferred from the tank 20 to the piping line 1 by the pressure difference according to the height, the position of the leak test apparatus 10 and the tank 20 is positioned higher than the piping line 1. The positional restrictions that must be followed.

도 2에 도시된 바와 같이, 통합 누수시험장치(100)는 선박의 배관라인(1)에 각각 연결되는 분기관(110)들과, 분기관(110)들이 연결된 통합관(120)과, 통합관(120)에 형성되며 외부 유체공급라인과 연결되는 유입관(130)과, 유입관(130)을 통해 유입된 유체를 펌프(140)로 이송하는 펌프이송관(150)과, 펌프(140)에서 통합관(120)으로 연결된 가압관(160)을 포함하며, 분기관(110), 유입관(130), 펌프이송관(150), 가압관(160)에는 밸브가 장착되며 각 분기관(110)에는 압력게이지(180)가 장착된다.As shown in FIG. 2, the integrated leak test apparatus 100 is integrated with branch pipes 110 connected to the pipe line 1 of the ship, and the integrated pipe 120 to which the branch pipes 110 are connected. An inlet pipe 130 formed in the pipe 120 and connected to an external fluid supply line, a pump transfer pipe 150 for transferring the fluid introduced through the inlet pipe 130 to the pump 140, and the pump 140. Including the pressure pipe 160 connected to the integrated pipe 120, the branch pipe 110, inlet pipe 130, pump transfer pipe 150, the pressure pipe 160 is equipped with a valve and each branch pipe (110) ) Is equipped with a pressure gauge 180.

아래에서는 이와 같이 구성된 통합 누수시험장치에 대해 구체적으로 설명한다.Hereinafter, the integrated leak test apparatus configured as described above will be described in detail.

통합관(120)의 일측에는 분기관(110)들이 정렬되어 형성되고, 분기관(110)에는 선박의 배관라인(1)이 각각 연결된다. 그리고 통합관(120)에는 벤트 밸브(190)가 장착된다.Branch pipes 110 are arranged on one side of the integrated pipe 120, the pipe line 1 of the vessel is connected to the branch pipe 110, respectively. And the vent valve 190 is mounted to the integrated pipe (120).

한편, 통합관(120)의 타측으로는 유입관(130)이 연결되며, 유입관(130)은 외부 유체공급라인이 연결된다. 그리고 유입관(130)에는 펌프이송관(150)이 연결되는데, 펌프이송관(150)으로는 외부 유체공급라인을 통해 유입된 유체의 일부가 펌프이송관(150)을 통해 펌프(140)로 공급된다.On the other hand, the inlet pipe 130 is connected to the other side of the integrated pipe 120, the inlet pipe 130 is connected to the external fluid supply line. In addition, a pump transfer pipe 150 is connected to the inlet pipe 130, and a part of the fluid introduced through the external fluid supply line to the pump transfer pipe 150 is supplied to the pump 140 through the pump transfer pipe 150.

그리고 펌프(140)에서 통합관(120)으로 연결된 가압관(160)으로는 펌프(140)에서 강제 이송된 유체가 통합관(120)으로 유입되면서 통합관(120)에서 배관라인(1)으로 유체가 신속하게 유입되어 배관라인(1)에 유체를 채운다. 이와 같이 펌프(140)에서 이송된 유체가 배관라인(1)으로 유입되면서 압력이 높아지게 되고, 배관라인(1)에 가해지는 압력은 각 분기관(110)에 장착된 압력게이지(180)를 통해 확인할 수 있다.And the pressurized pipe 160 connected to the integrated pipe 120 in the pump 140, the fluid forcibly transported from the pump 140 flows into the integrated pipe 120, from the integrated pipe 120 to the pipe line (1) The fluid flows in quickly and fills the fluid in the pipe line (1). As the fluid transferred from the pump 140 flows into the pipe line 1 as described above, the pressure is increased, and the pressure applied to the pipe line 1 is provided through the pressure gauge 180 mounted to each branch pipe 110. You can check it.

한편, 이와 같은 유체의 흐름을 제어하는 밸브들이 통합 누수시험장치(100)의 각 관에 설치되며, 배관라인(1)과 연결되지 않은 분기관(110)의 밸브는 닫는다.On the other hand, the valves for controlling the flow of the fluid is installed in each pipe of the integrated leak test apparatus 100, the valve of the branch pipe 110 is not connected to the pipe line (1) is closed.
