In the process of crude oil transmission, since the density of water is greater than that of crude oil, when the water and oil in the oil pipeline are separated, the water is in the lower layer of the oil pipeline, and the crude oil is in the upper layer of the oil pipeline. When the liquid (water-oil mixture) in the oil pipeline ) flows through the first connecting pipe 12, the water in the oil pipeline flows preferentially from the first connecting pipe 12 to the liquid collecting container 11, after the water flows into the liquid collecting container 11, if there is still free capacity in the liquid collecting container 11, Then part of the crude oil in the oil pipeline also flows into the liquid collection container 11 . Since the density of water is greater than that of crude oil, the water and crude oil in the liquid collection container 11 will form layers, with water in the lower layer and crude oil in the upper layer. Since the liquid outlet B is located at the bottom of the liquid collection container 11, when the first control valve 13 is opened, the water is preferentially discharged from the liquid collection container 11 because the water is in the lower layer.

The heating device 19 is arranged on the outer wall of the second connecting pipe 14 .

Specifically, the safety device 17 can be sleeved on the second control valve 13, and optionally, the safety device 17 can be a safety lock. When the first control valve 13 needs to be controlled, the safety device first needs to be opened, and the first control valve 13 can be controlled only after the safety device is opened. In this way, the situation that the crude oil in the oil pipeline is stolen can be effectively avoided. For example, when the safety device is a safety lock, the operator needs a key of the safety lock to open the safety lock and control the first control valve 13 .

In practical application, when the pressure of crude oil in the oil pipeline is low, the accumulated water in the liquid collection container 11 may not be discharged from the first control valve 13 through the second connecting pipe 14 smoothly.
