How to operate the high-pressure reactor 2

(3) Installation and sealing of the cauldron body and cauldron cover: The cauldron body and cauldron cover use line contact between the gasket or the conical surface and the arc surface. By tightening the main nut, they press each other to achieve a good sealing effect. Tighten the nut. When tightening, it must be tightened diagonally and symmetrically multiple times and gradually, with uniform force. The kettle lid is not allowed to tilt to one side to achieve a good sealing effect. When tightening the main nut, the specified tightening torque range of 40~120NM must not be exceeded to prevent the sealing surface from being damaged. If it is squeezed or overloaded, the sealing surface should be specially taken care of. Before each installation, wipe the upper and lower sealing surfaces clean with soft paper or cloth. Pay special attention not to scratch the sealing surfaces of the cauldron body and cauldron lid. If reasonable, The operation can be used more than tens of thousands of times. After the sealing surface is damaged, it needs to be reprocessed and repaired to achieve good sealing performance. When disassembling the cauldron cover, the cauldron cover should be slowly lifted up and down to prevent the sealing surfaces between the cauldron body and the cauldron cover from interacting with each other. collision. If the seal uses a gasket seal (PTFE, aluminum pad, copper pad, asbestos pad, etc.), a good sealing effect can be achieved by tightening the main nut.
