Specifically, the side wall of the middle tube 3 is provided with an opening 10 adapted to the valve plate 8, and the opening 10 transversely penetrates through the inner hole of the middle tube 3. Further, the valve plate 8 is made of corrosion-resistant rubber. The corrosion-resistant rubber material has certain hardness and can keep the rectangular shape. The other reason for adopting the corrosion-resistant rubber material is to maintain the tightness between the valve plate 8 and the opening 10, and the corrosion of crude oil is resisted, so that the service life is prolonged. An output shaft of the driver 9 is fixedly connected with the valve plate 8, and the driver 9 drives the valve plate 8 to be inserted into the middle pipe 3 so as to block the middle pipe 3; the driver 9 and the valve plate 8 are both close to one end of the middle pipe 3 connected with the oil storage container 1, and the liquid inlet pipe 6 is close to one end of the middle pipe 3 connected with the hollow pipe 2.

the first flushing method is as follows: the control panel 12 is provided with a forward flushing button, a backward flushing button and a stop button, and the control panel 12 realizes one-key decontamination, so that time and labor are saved. The specific operation is as follows: if the forward flushing button is pressed, the valve plate 8 of the upper hollow pipe 2 is closed, meanwhile, the valve plate 8 of the lower hollow pipe 2 does not act and remains open, and high-pressure clean water or high-pressure steam of an external cleaning pipeline is introduced into the liquid inlet pipe 6 of the upper hollow pipe 2, so that forward flushing decontamination from top to bottom is formed. If the back flushing button is used, the valve plate 8 of the lower hollow pipe 2 is closed, meanwhile, the valve plate 8 of the upper hollow pipe 2 is not actuated and kept open, and high-pressure clean water or high-pressure steam of an external cleaning pipeline is introduced into the liquid inlet pipe 6 of the lower hollow pipe 2, so that back flushing decontamination from bottom to top is formed. The forward flushing decontamination and the reverse flushing decontamination are combined, so that the flushing effect is improved, the possibility of dirt blockage is further reduced, and the liquid level meter can more accurately reflect the liquid level in the oil storage container 1.
The second flushing method: the control panel 12 is provided with an automatic flushing button, the automatic flushing button is pressed, the flow detector 14 automatically detects the current flow in the hollow tube, if the flow is zero or smaller than a set value, the control panel 12 alarms and automatically executes the forward flushing decontamination and the reverse flushing operation, thereby realizing automatic decontamination. In addition, since the flow rate may be small in the case of stable liquid level, it is difficult to determine whether the liquid is clogged, the control panel 12 may set the periodic flushing mode, thereby avoiding the problem.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description.
