FIXTURE FOR SAFE HANDLING AND TRANSPORT OF EMERGENCY STOP VALVE AND CONTROL VALVE ( ESV-CV) OF 660MW STEAM TURBINE OF A THERMAL POWER PLANT

摘要

A fixture for safe handling and transport of emergency valve and control valve (ESV-CV) of 660MW steam turbine consists of a base made of I-section beams, ten in numbers out of which five are parallel in horizontal plane and remaining five intersecting them at right angle and are also horizontal. These I-sections beams (1,2) are connected to three vertical columns (3) whose height is kept in between 385 to 685 mm when each column contains three vertical beams (4). A horizontal beam is disposed at the top of these vertical columns (3). Bottom 10 beams (1, 2) are adjusted in such away that they fall just below the columns (3) to support them. A wooden block (6) is fastened with the horizontal channel (5) and ESV-CV (7) sits over this wooden block (6). Stiffeners (8) are provided to arrest the transverse movement of vertical columns (3).
