The oil mist lubrication output pipe adopts flange connection, and the sealing method is sealing ring sealing. A flange short section is added to the upper connection method, making the installation on the switching valve more convenient and stable, avoiding oil leakage and seepage, and being easy to repair.

[0005] To achieve the above object, the specific technical solution of the utility model is as follows:

[0006] An oil mist output pipe in an oil mist lubrication system includes a switching valve and an output pipe device. An oil mist output port is provided on the switching valve. The lower end of the output pipe device is fixedly connected with a lower flange. Vertically downwardly arranged first locking bolts are circumferentially arranged and clamped on the lower flange. The lower flange is locked and fixed in the oil mist output port through the first locking bolts. The upper end of the output pipe device is fixedly connected with an upper flange. Vertically upwardly arranged second locking bolts are circumferentially arranged and clamped on the upper flange.

[0007] As a further setting of the above solution, the output pipe device includes an output pipe, and a corrugated pipe is arranged in the middle of the output pipe. The corrugated pipe can bend and contract freely.

[0008] As a further setting of the above solution, the lower flange includes a lower flange disc. First through holes are circumferentially arranged on the outer edge of the lower flange disc. A lower sealing installation boss is arranged at the center of the lower end face of the lower flange disc. A first sealing ring is clamped on the outer cylindrical surface of the lower sealing installation boss. The lower flange is clamped on the oil mist output port through the lower sealing installation boss. The first locking bolts are threadedly connected with the switching valve through the first through holes. Rotate the first locking bolts to fixedly connect the lower flange to the switching valve, and ensure the sealing effect through the first sealing ring.

[0009] As a further setting of the above solution, the upper flange includes an upper flange plate. The outer edge of the upper flange plate is provided with second through holes arranged in a circumferential pattern. The center of the upper end face of the upper flange plate is provided with an upper sealing installation boss. A second sealing ring is clamped on the outer cylindrical surface of the upper sealing installation boss. The second locking bolt is threadedly connected to the top cover through the second through hole, and the upper flange is fixedly connected to the top cover by rotating the second locking bolt.
