The specific technical scheme is as follows:

a pipeline oil drain device comprises a sealing part and a sewage discharge part, and is characterized in that the sealing part is directly fixed and communicated with a pipeline, the sewage discharge part vertically penetrates through the middle part of the sealing part and is positioned below the sealing part, the sewage discharge part is in a hollow column shape, one end of the sealing part is a circular oil inlet matched with the pipeline, and the other end of the sealing part is a buffer surface with an included angle of 45 degrees with the horizontal plane of the sewage discharge part; install sealed apron in the middle of the buffering face, it has the through-hole to open in the middle of the sealed apron, the through-hole is provided with the cone to the inside extension of seal part, the inside coiling of sealed apron has the sealing washer.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
