[0029] Please refer to Figures 1-3 , a petrochemical mechanical seal flushing system, including a water tank 1, please refer to Figure 1 and Figure 2, on one side of the water tank 1, a flushing cylinder 11 is installed, which can be sleeved at the sealing position for flushing. The waste water is collected from the outlet at the bottom for reflux, which is safe, stable and convenient for operation. On one side surface of the flushing cylinder 11, a partition 12 is fixedly connected. On one side surface of the partition 12, a flushing pipe 13 is fixedly connected. At one end of the flushing pipe 13, a single nozzle 14 is fixedly installed, which can spray water for flushing at a single position, for local key cleaning and is convenient for adjustment. The single nozzle 14 is located at the central position inside the flushing cylinder 11. On one side surface of the flushing cylinder 11, a flushing ring 15 is fixedly installed. Inside the flushing ring 15, there is an annular cavity 16. On one side surface of the annular cavity 16, an annular nozzle 17 is fixedly installed, which can spray water in an annular direction, is beneficial for global flushing, convenient for detection, safe and efficient, and convenient for adjustment and use. The annular nozzle 17 is fixedly installed on the side surface of the flushing ring 15. On one side surface of the annular cavity 16, a connecting pipe 18 is fixedly connected. One end of the connecting pipe 18 is fixedly connected to the side surface of the partition 12. On the other end surface of the flushing cylinder 11, an adjusting pipe 2 is slidably installed, which can slide and adjust the position for alignment water supply, is convenient and stable. One end of the adjusting pipe 2 is fixedly connected to a docking plate 21.

[0030] Please refer to Figure 1 and Figure 2 , on both side surfaces of the adjusting pipe 2, adjusting screws 22 are threadedly connected. One end of the adjusting screws 22 is rotatably installed on the side surface of one end of the flushing cylinder 11. By connecting the adjusting pipe 2 with the adjusting screws 22, the position can be adjusted by threading for switching, which is convenient and stable. On one side surface of the flushing cylinder 11, there is a sealing hole 23. The side surface of the sealing hole 23 is slidably connected to the surface of the adjusting pipe 2. By connecting the adjusting pipe 2 through the sealing hole 23, sealing can be ensured while sliding adjustment, avoiding leakage. The other end of the adjusting pipe 2 is fixedly connected to a hose 24. One end of the hose 24 is fixedly installed with a water pump 25. By installing the water pump 25 through the hose 24, continuous water supply is facilitated, interference is avoided, and adjustment and use are convenient.

[0031] Please refer to 1 and Figure 3 , at one end of the flushing pipe 13, there is a connecting cylinder 26. The connecting cylinder 26 is fixedly connected to the other side surface of the partition 12. On one side surface of the connecting cylinder 26, a sealing plate 27 is slidably installed. On one side surface of the sealing plate 27, a push rod 28 is fixedly connected. By installing the sealing plate 27 and the push rod 28 through the connecting cylinder 26, alignment water supply can be adjusted during adjustment, avoiding confusion, being safe and stable. One end of the push rod 28 tightly abuts against the side surface of the docking plate 21. On the other side surface of the sealing plate 27, a tightening spring 29 is slidably installed. By connecting the sealing plate 27 with the tightening spring 29, it can tightly assist in sealing and avoid backflow leakage, being safe and efficient. At one end of the flushing cylinder 11, there is a connecting flange 3. On the surface of the connecting flange 3, a sealing ring 31 is fixedly connected. By installing the sealing ring 31 through the connecting flange 3, alignment installation is facilitated, and the safety and stability of flushing are ensured.

[0032] During use, the connecting flange 31 can be installed on the petrochemical machinery, and then the flushing cylinder 11 can be aligned to the sealing position. Start the water pump 25 to supply water into the inside of the hose 24. At this time, the adjusting screw 22 can be rotated to push the adjusting pipe 22 to move. When the docking plate 21 is located on one side of the partition plate 12, the water flow can enter one side of the partition plate 12, and then enter the inside of the annular cavity 16 through the connecting pipe 18, and then evenly spray out from the annular nozzles 17 arranged on the side, so as to perform large-area flushing on the sealing position to ensure cleanliness. At the same time, when the adjusting pipe 2 is pushed inward, the docking plate 21 is aligned to the surface of the connecting cylinder 26, and the sealing plate 27 is pushed open by the push rod 28 to open the flushing pipe 13. The water flow does not enter the side of the partition plate 12, but directly sprays out from the single nozzle 14, so as to directly perform high-pressure flushing on the key central part, and then check the sealing performance of the sealing position, which is beneficial to adjustment and use, safe and efficient, and has high adaptability.
