However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] In the field of ship engine equipment, water quality testing of ballast water treatment devices is a key link, which is directly related to the safety of marine ecosystems and human health. Therefore, it is necessary to configure a sampling short tube on the ballast water treatment system pipeline. The setting of the sampling short tube enables the testers to easily obtain water samples from different positions of the ballast water treatment system, and then conduct a comprehensive and accurate test of the water quality.

[0025] During the voyage, the quality of ballast water needs to be continuously monitored to ensure that it complies with environmental regulations and the requirements of the International Maritime Organization (IMO). The sampling short pipe allows crew members or testers to regularly extract water samples from the ballast water system for chemical, biological and other analysis, so as to promptly detect and deal with water quality problems.

[0026] With respect to the above-mentioned related technologies, the inventors believe that the current design of the sampling short tube of the ballast water treatment system is relatively complicated and difficult to install and replace.

[0027] In order to facilitate the installation and use of the sampling short tube and to better meet the requirements of water quality inspection sampling, the present application provides a ballast water treatment system sampling short tube.

[0028] The following is combined with Figure 1 This application is described in further detail.

[0029] The present application embodiment discloses a ballast water treatment system sampling short tube. Figure 1 A ballast water treatment system sampling short tube includes a liquid inlet connecting pipeline 1, a sampling component 2 is arranged at the bottom end of the liquid inlet connecting pipeline 1, and a liquid outlet connecting pipeline 3 is arranged on the side of the sampling component 2 away from the liquid inlet connecting pipeline 1, the inner diameter of the liquid inlet connecting pipeline 1 is larger than the inner diameter of the liquid outlet connecting pipeline 3, the sampling component 2 separates the liquid inlet connecting pipeline 1 and the liquid outlet connecting pipeline 3, so that the medium from the inside of the liquid inlet connecting pipeline 1 passes through the filtration of the sampling component 2 and enters the inside of the liquid outlet connecting pipeline 3 for discharge, thereby intercepting the sampling impurities located inside the medium through the sampling component 2.

[0030] The liquid inlet connecting pipeline 1 is a tubular structure. In some embodiments, the liquid inlet connecting pipeline 1 is made of a stainless steel pipe. An elbow joint 11 is fixedly connected to the top of the liquid inlet connecting pipeline 1. The elbow joint 11 is a curved structure, and the interior of the elbow joint 11 is relatively connected to the interior of the liquid inlet connecting pipeline 1.

[0031] One end of the elbow joint 11 is fixedly connected to the liquid inlet pipeline, and the liquid inlet end of the elbow joint 11 is located at the end away from the liquid inlet connecting pipeline 1, and the liquid outlet end of the elbow joint 11 is located at the end close to the liquid inlet connecting pipeline 1, so that the medium enters the interior of the elbow joint 11 from the liquid inlet end of the elbow joint 11, and enters the interior of the liquid inlet connecting pipeline 1 from the liquid outlet end of the elbow joint 11 through the guidance of the elbow joint 11.

[0032] The axis of the liquid inlet end of the elbow joint 11 is staggered with the axis of the liquid inlet connecting pipeline 1, and the axis of the liquid outlet end of the elbow joint 11 is relatively coaxial with the axis of the liquid inlet connecting pipeline 1, so that the medium inside the pipeline at different angles is guided into the interior of the liquid inlet connecting pipeline 1 through the elbow joint 11.

[0033] The outer wall of the inlet connecting pipeline 1 is sleeved with a first connecting flange 12, which is coaxially arranged with the inlet connecting pipeline 1. The sealing surface of the first connecting flange 12 faces away from the outlet connecting pipeline 3.

[0034] The outer wall of the liquid outlet connecting pipeline 3 is sleeved with a second connecting flange 31, which is coaxially arranged with the liquid outlet connecting pipeline 3. The sealing surface of the second connecting flange 31 faces the side away from the liquid inlet connecting pipeline 1.

[0035] The sampling assembly 2 includes a top fixing flange 21 located near the liquid inlet connecting pipeline 1, and a bottom fixing flange 22 is provided on the side of the top fixing flange 21 near the liquid outlet connecting pipeline 3. The top fixing flange 21 is fixedly connected to the liquid inlet connecting pipeline 1, and the bottom fixing flange 22 is fixedly connected to the liquid outlet connecting pipeline 3.

[0036] A filter gasket 23 is provided between the top fixing flange 21 and the bottom fixing flange 22, and the filter gasket 23 separates the top fixing flange 21 and the bottom fixing flange 22. A gasket is coaxially fixedly connected to the outer wall of the filter gasket 23, and the top of the gasket is opposite to the top fixing flange 21, the bottom of the gasket is opposite to the bottom fixing flange 22, and the filter gasket 23 is opposite to the hollow part of the top fixing flange 21. A retention hole is provided on the filter gasket 23, and the diameter of the retention hole is smaller than the diameter of the sampled material to be retained, so that the sampled material is retained and sampled through the retention hole.

[0037] The position on the sampling component 2 where the filter screen gasket 23 is provided is the working surface of the sampling component 2. The medium is sampled and intercepted through the filter screen gasket 23, and the area of the working surface inside the sampling component 2 is larger than the inner diameter area of the liquid inlet connecting pipeline 1, so that the medium inside the liquid inlet connecting pipeline 1 can be completely sampled through the working surface inside the sampling component 2.

[0038] In some embodiments, the filter screen gasket 23 is a copper wire mesh gasket, and the outer gasket is made of nitrile rubber.
