[0026] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the control member 5 is composed of a control ring 501, a control rod 502 and a sealing gasket 503, and the inner wall of the control ring 501 is fixedly welded to the outer wall at the top of the control rod 502, the outer wall of the control rod 502 near the center is fixedly connected to the inner wall of the sealing gasket 503, and the outer wall of the control rod 502 near the bottom is threadedly connected to the inner wall of the first blocking column 401, and the outer wall of the sealing gasket 503 is rotatably connected to the inner wall of the main pipeline 101.

At this time, the valve is in a fully closed state. The control rod 502 is driven to rotate by rotating the control ring 501. The first blocking column 401 cannot rotate to make vertical linear motion under the action of the sliding block 402, and the first blocking column 401, the second blocking column 404 and the third blocking column 406 all move upward.

[0027] The use method and advantages of the utility model: When the lubricating oil pipeline valve with bypass function is working, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the valve is in a fully closed state by default. The control rod 502 is rotated by rotating the control ring 501. The first blocking column 401 cannot rotate and make vertical linear motion under the action of the sliding block 402. The first blocking column 401, the second blocking column 404 and the third blocking column 406 all move upward. After moving to a certain distance, a gap appears between the second blocking column 404 and the main channel 302, allowing the lubricating oil to flow out through the main channel 302. After continuing to rotate the control ring 501, the third blocking column 406 closes the main channel 302. At this time, the first blocking column 401 and the bypass channel 304 are separated. A gap appears between the two channels, and the lubricating oil enters the bypass channel 304 through the shunt channel 303. When the main channel 302 is blocked, the oil can be guided to the bypass channel 304 by rotating the control ring 501, thereby protecting the system from damage. The pressure sensor 202 monitors the pressure in the main pipeline 101 in real time. The rotating control ring 501 can adjust the opening and closing angles between the channels, accurately control the flow of the oil, reduce unnecessary energy waste, and improve the overall operating efficiency of the system.
