The embodiment of the application provides a pipeline 100. The conduit 100 is used to transport fluids. The fluid may be a liquid or a gas.

The pipe 100 comprises a pipe wall 10 and a one-way flow-through device 30 arranged in the pipe wall 10. The pipe wall 10 is used for transporting fluids. The flow-through device 30 is used to restrict the flow direction of the fluid in the pipe wall 10 to prevent the fluid from flowing backwards.

In the illustrated embodiment, the tube wall 10 is rectangular parallelepiped (channel-shaped). It will be appreciated that in other embodiments, the tube wall 10 may also be circular or other shapes.

The pipe wall 10 surrounds a channel 101 formed to convey fluid. The channel 101 has at least one inlet 1012 and at least one outlet 1014 for fluid to enter and exit, respectively.

The pipe wall 10 includes a first wall 12 and a second wall 14 disposed in parallel and opposite to each other.

The one-way flow device 30 includes a plurality of first baffles 31 and a plurality of second baffles 32. The length of the first baffle 31 is greater than the length of the second baffle 32. The first baffles 31 and the second baffles 32 are disposed on the tube wall 10 at intervals.

Specifically, the first flow deflectors 31 are connected and fixed to the pipe wall 10 by bolts, and the two ends of the bolts are clamped by clamp springs.

Both ends of each first baffle 31 are in contact with the bottom and the top of the tube wall 10, respectively. Each second baffle 32 is spaced from the bottom and top of the tube wall 10.

In the illustrated embodiment, the first baffles 31 and the second baffles 32 are disposed on the first wall 12 and the second wall 14, respectively. It is understood that, in other embodiments, the plurality of first deflectors 31 and the plurality of second deflectors 32 may also be disposed on one of the first wall 12 and the second wall 14.

The plurality of first baffles 31 and the plurality of second baffles 32 separate the channel 101 to form a first channel 1016 and a second channel 1018. The first channel 1016 is a region where the plurality of first baffles 31 are offset from the plurality of second baffles 32, i.e., a middle region in the figure. Second passage 1018 is an area where a plurality of first baffles 31 and a plurality of second baffles 32 are located.

In the illustrated embodiment, the first baffle 31 is rotatably mounted to the pipe wall 10. Preferably, the included angle between the first guide plate 31 and the pipe wall 10 can be adjusted between 30 degrees and 45 degrees.
