Description

Integrated Leak Tester {LEAKAGE TESTER}

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.

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.

1 is a conceptual diagram showing a leak test apparatus according to the prior art.

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.

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.

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.

Republic of Korea Utility Model Registration No. 20-0382978 (Notification Date; 2005.04.29)

The present invention has been invented to solve the problems of the prior art as described above, and an object thereof is to provide an integrated leak test apparatus configured to apply pressure by driving a pump while connected to a ship's piping line.

Integrated leakage test apparatus according to the present invention for achieving the above object is an integrated pipe formed with branch pipes connected to the ship's piping line, the inlet pipe is formed on the side of the integrated pipe is connected to the external fluid supply line, and the inflow Technical features include a pump conveying pipe branched from the pipe extending to the pump, and a pressure pipe extending from the pump to the integrated pipe.

In addition, according to a preferred embodiment of the present invention, the inlet pipe, the pump transfer pipe, the pressure pipe and the branch pipe is equipped with a valve.

In addition, according to a preferred embodiment of the present invention, the integration pipe is equipped with a vent valve.

In addition, according to a preferred embodiment of the present invention, the branch pipe is equipped with a pressure gauge for measuring the pressure of the pipe line.

As described above, in the integrated leak test apparatus according to the present invention, a part of the fluid supplied while the ship's piping line is connected to each branch pipe flows into the pipe line and the other part flows into the pump to apply pressure to the pipe line. Can be. Therefore, there is an advantage that the leak test can be performed quickly because the pressure can be applied at the same time while filling the pipe line with fluid.

1 is a conceptual diagram showing a leak test apparatus according to the prior art.
2 is a perspective view showing an integrated leak test apparatus according to the present invention,
3 is a conceptual diagram showing the fluid flow of the integrated leak test apparatus shown in FIG.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the integrated leak test apparatus according to the present invention will be described in detail.

2 is a perspective view showing an integrated leak test apparatus according to the present invention, Figure 3 is a conceptual diagram showing the fluid flow of the integrated leak test apparatus shown in FIG.

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.

Hereinafter, the integrated leak test apparatus configured as described above will be described in detail.

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).

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.

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.

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.

Therefore, the fluid supplied through the external fluid supply line is filled in the piping line (1) of the ship and the pressure is applied to the piping line (1) by the operation of the pump 140 to pressurize the leak of the piping line (1) 180).

On the other hand, after the leak test is completed, the pump 140 is stopped, the vent valve 190 is opened to release the pressure, and then the pipe line 1 connected to the branch pipe 110 is dismantled.
