Abstract
The present disclosure relates to a differential pressure driven burst-pipeline emergency blocking system. The system includes a valve body with flanges on opposite axial ends, a cylindrical valve sleeve connected with the inner wall of a flange end and having a through-hole in the valve sleeve wall. The wall of the valve sleeve is in movable fit with a valve spool having a U-shaped section. The working fluid through-hole in the valve sleeve is communicated with the inner chamber of the valve body and can be closed by a cylindrical surface of the valve spool. A horizontal push rod is in movable fit with a central hole at the left end of the valve spool, and opposite ends of the horizontal push rod are in movable fit with axial orifices of left and right support seats in the valve body respectively.
