Description

Oil drain device

Technical Field

The utility model relates to an oil field oil recovery apparatus technical field specifically is an oil drainer.

Background

When crude oil is produced, the oil pipe is connected with an oil pump and is lowered into an oil well. After the production is finished, when the oil pipe is taken out of the oil well, liquid in the oil pipe is easy to spill onto the ground of the wellhead, and the well site environment pollution is caused. In order to solve the problem, an oil drain device is usually connected to the oil well pump, an oil drainage channel on the oil drain device is communicated with an oil pipe and an annular space between the oil pipe and the sleeve, and liquid in the oil pipe can be discharged into the annular space through the oil drainage channel.

In the oil drain device described in the publication No. CN 204552686U, the movable central tube moves inside the outer sleeve, the outer sleeve has poor sealing effect on the movable central tube, and the poor sealing performance can cause oil leakage.
