At this time, pulling the limit rod 11 can make the discharge hole 2 open, so that the corrosion inhibitor enters the feed barrel 4 to complete the quantitative measurement of the corrosion inhibitor. A conduit 7 is fixedly connected to one side of the feed barrel 4, and one end of the conduit 7 is fixedly connected to the discharge pipe 8. A through hole 9 is opened on one side of the feed barrel 4 and the feed barrel 4 is fixedly connected to a sealing sleeve 10 on the side of the through hole 9. A limit rod 11 is inserted in the sealing sleeve 10, and the limit rod 11 is located in the sealing sleeve 10 and is sleeved with a spring. The limit rod 11 is located in the sealing sleeve 10 and is fixedly connected to a limit plate 12.

[0018] The air plate contacts the stopper 13 , and the stopper 13 is fixedly connected to the limiting rod 11 . The stopper 13 can block the closing plate 3 .
