The first end of the fourth pipeline 5 is located between the first end of the third pipeline 4 and the suction inlet. The second end of the fourth pipeline 5 is located between the second end of the third pipeline 4 and the second inlet and outlet interface 7. Meanwhile, valves are respectively arranged on the first pipeline 2, the second pipeline 3, the third pipeline 4 and the fourth pipeline 5 to realize the on-off of each pipeline. Specifically, when the pipeline system is in forward conveying, the first pipeline 2 and the second pipeline 3 are controlled to be turned on, and the third pipeline 4 and the fourth pipeline 5 are controlled to be turned off. The medium enters from the first inlet and outlet interface 6 and flows out from the second inlet and outlet interface 7. When the pipeline system is in reverse conveying, the third pipeline 4 and the fourth pipeline 5 are controlled to be turned on, and the first pipeline 2 and the second pipeline 3 are controlled to be turned off. The medium enters from the second inlet and outlet interface 7 and flows out from the first inlet and outlet interface 6.

[0041] The valves on the pipeline are controlled according to the needs of the conveying direction of the pipeline system; when the first pipeline 2 and the second pipeline 3 are conducted, the third pipeline 4 and the fourth pipeline 5 are cut off, the medium enters from the first inlet-outlet interface 6 and flows out from the second inlet-outlet interface 7, and the pipeline system is in forward conveying; when the third pipeline 4 and the fourth pipeline 5 are conducted, the first pipeline 2 and the second pipeline 3 are cut off, the medium enters from the second inlet-outlet interface 7 and flows out from the first inlet-outlet interface 6; by setting the above pipelines and valves, the forward conveying and reverse conveying of the pipeline system can be realized according to needs, the system requirements can be met, and the system versatility is improved.
