Methylsulfonamide production detection sampling device

The utility model relates to the technical field of methyl sulfonamide production, in particular to a detection sampling device for methyl sulfonamide production. According to the technical scheme, the device comprises a movable rod, an adjusting barrel and a sampling pipe, the movable rod is movably installed at the top of the adjusting barrel, an operation disc is fixedly installed at the top of the movable rod, a threaded rod extending into the adjusting barrel is fixedly installed at the bottom of the movable rod, a piston frame is rotatably installed at the bottom of the threaded rod, and a threaded sleeve is installed on the outer side of the threaded rod in a threaded mode; the bottom of the adjusting cylinder is in threaded connection with a sampling pipe. The movable column, the threaded rod and the piston frame are matched with one another, so that the moving distance of the piston frame can be controlled, methanesulfonamide can be conveniently and quantitatively sucked into the sampling pipe, and t
