FIELD: gas and oil production. ^ SUBSTANCE: device for shutoff of emergency hole of pipeline corresponds to plug including rod made of rigid solid or flexible material at one end of which there is located cylinder brush. Bristle or nap of the cylinder brush are made of flexible elastic material, for example, sections of metal wire secured radially around surface of the rod. Also, the rod of the plug can be solid or hollow in form of a pipe with a through orifice. On opposite from the cylinder brush side the through orifice of the rod is equipped with a shut-off device functioning as a gate of slide. ^ EFFECT: simple design of device, increased reliability of emergency pipeline shutoff facilitating collection of flowing out fluid; reduced time for assembly of device both on earth surface and in deep water regions difficult to access. ^ 3 cl, 8 dwg |
