The utility model discloses be applied to chemical equipment and want the orificial shutoff problem of shutoff, consequently mainly play the shutoff effect through baffle, inner tube and the internal stay on this component. The plugging element mainly comprises a handle and a pull rod which are integrally connected, wherein threads are arranged on the pull rod, then the lower end of the pull rod is in threaded connection with an inner support after the pull rod penetrates through a baffle, a nut is further in threaded connection with the pull rod and is positioned between the baffle and the handle, and a gap of 0.1-0.5 mm is arranged between the pull rod and the baffle, so that the handle and the pull rod can pull up the inner support during operation; the inner support can lean on the inner tube after being pulled up, because evenly processing has square notch on the section of thick bamboo wall of inner tube, and the tip establishes to the bevel shape under the inner tube, the bevel face at bevel angle is inwards, consequently the inner support can prop inner tube bar edge for the back taper, extrudees mutually with shutoff mouth of pipe inner wall, in order to prevent the inner support decline, consequently utilizes the nut fastening on the pull rod, makes its position of inner support fixed, can prevent that the shutoff component is not hard up to drop this moment, and effectual prevention equipment is depositing, inside the transportation in debris entering equipment. The utility model discloses the specific operation does: the plugging element is placed at the plugging pipe orifice, the inner barrel and the inner support stretch into the pipe orifice, the baffle is pressed against the pipe orifice, the pull rod and the inner support are pulled up by the handle, the inner support abuts against the inner barrel after being pulled up, the strip-shaped edge of the inner barrel is supported into an inverted cone shape and is extruded with the inner wall of the plugging pipe orifice, then the inner support is fastened by screwing a nut, the position of the inner support is fixed, the inner support is prevented from descending, the plugging element is prevented from loosening and falling, and the plugging of the plugging pipe orifice is finished at the moment.

Preferably, the parts in the plugging element are made of steel materials.

Compared with the prior art the utility model discloses following beneficial effect has: the utility model provides a chemical industry equipment welding seam shutoff component adopts steel shutoff component, utilizes the locking of back taper inner tube and utilizes the nut to prevent that the internal stay from dropping, convenient operation, stable in structure, effectual carries out the shutoff to the welding seam, prevents inside equipment is depositing, transportation in debris entering equipment, pollution equipment has also prevented simultaneously that the shutoff component is not hard up to drop.
