A top column 504 is fixedly connected to the middle of the upper end of the circular closing plate 5, and a slot 405 is connected to the upper end of the circular movable groove 403. A monitoring alarm device 6 is connected to the upper end of the circular automatic closing component 4, and a connecting column 601 is fixedly connected to the lower end of the monitoring alarm device 6. A pressure sensor 603 is fixedly connected to the lower end of the connecting column 601, and a connecting pipe 7 is connected to the outer side of the connecting column 601.

[0024] Furthermore, one end of the chemical pipe 2 and both ends of the monitoring pipe 1 are fixedly connected with a connecting plate 3 , and the connecting plate 3 on the chemical pipe 2 and the connecting plate 3 on the monitoring pipe 1 are fixedly connected by bolts 301 .

The lower end of the pressure pipe 502 passes through the circular socket 101 and extends to the inside of the monitoring tube 1. When the chemical pipe 2 transports liquid through the pressure pipe 502, the liquid part enters the pressure chamber 503 and lifts the circular closing plate 5 by the liquid transport pressure.

[0026] Furthermore, four guide rods 404 pass through four circular holes 501 on the circular closing plate 5 respectively, and the upper end of the top column 504 is inserted into the slot 405.

When the monitoring alarm device 6 or its accessories fail, the connecting pipe 7 is rotated in the opposite direction to remove the connecting column 601 from the inside of the slot 405 to repair the monitoring alarm device 6 or its accessories. At the same time, when the connecting column 601 is removed, the liquid delivery pressure will continue to lift the circular closing plate 5, so that the circular closing plate 5 rises and fits with the sealing gasket 407 to achieve sealing. At the same time, the sealing ring 402 seals the circular socket 101 and the pressure pipe 502, thereby realizing the automatic closure of the circular automatic closure 4 without stopping the transportation operation of the chemical pipe 2.
