Description

Technical Field

[0001] This utility model relates to the field of sampling technology for ballast water treatment systems, and specifically to a convenient sampling and testing device for ballast water treatment systems. Background Technology

[0002] The 2020 Trial Guidelines for Ballast Water Sampling and Analysis require ballast water to be sampled and analyzed. However, due to the varying forms and sizes of sampling devices provided by different ballast water treatment system manufacturers, installation on board is carried out according to each manufacturer's requirements. Since ballast water sampling and analysis are performed by third parties, their sampling may not meet the connection requirements of each manufacturer's sampling device. Therefore, designing a portable sampling connector suitable for sampling devices from various ballast water manufacturers would facilitate rapid sampling for all ship types.

[0003] Therefore, a convenient sampling and testing device for ballast water treatment systems is needed. Utility Model Content

Both ends of the main delivery pipe are connected to the delivery pipeline of the ballast water treatment system via flanges. A branch pipe is connected to the middle section of the main delivery pipe. The flange joint includes a third flange and a first fixed pipe. The end of the branch pipe away from the main delivery pipe is connected to the third flange via a second flange. The end face of the third flange away from the second flange is fixedly connected to the first fixed pipe. The surface of the first fixed pipe near the third flange is provided with a threaded layer, and a sealing groove is formed on the surface of the first fixed pipe near the threaded layer. A sealing groove is formed on the end face of the first fixed pipe away from the second flange. The hose joint includes a second fixed pipe, a first hose, and an anti-loosening nut.

When the flange joint and hose joint are installed, the sealing groove 1 and the sealing groove 3 are matched and connected, and a sealing ring 1 is provided between them. The sealing groove 2 and the sealing groove 4 are matched and connected, and a sealing ring 2 is provided between them. After the connection is completed, the thread layer 1 and the thread layer 2 are tightened by the anti-loosening nut sleeve. At the same time, the anti-loosening nut sleeve is installed in contact with the right angle groove to reinforce the installation of the fixed pipe 1 and the fixed pipe 2.

[0006] Preferably, a third fixing tube is provided inside the first fixing tube, and the third fixing tube abuts against the inner end face of the first insertion groove.
